+# forgecode — CLAUDE.md
+
+> **Fork of [tailcallhq/forgecode](https://github.com/tailcallhq/forgecode).**
+> Phenotype-org additions: `deny.toml` + `cargo-deny.yml` CI bootstrapped 2026-05-01.
+
+---
+
+This repo is a **fork** of the upstream [tailcallhq/forgecode](https://github.com/tailcallhq/forgecode)
+project — an AI-enhanced terminal development environment with ZSH plugin support,
+TUI, and multi-provider LLM integration.
+
+Do not rewrite upstream content. Any changes to upstream-origin files must be
+clearly annotated as Phenotype-org-specific additions.
+
+## Project Overview
+
+| Field | Value |
+|-------|-------|
+| Workspace | Multi-crate (21 internal crates under `crates/`) |
+| Edition | 2024 |
+| Rust version | 1.92 |
+| License | MIT |
+| Upstream | <https://github.com/tailcallhq/forgecode> |
+
+## Phenotype-Org Additions
+
+The following files are Phenotype-org-specific additions (not present in upstream):
+
+- `deny.toml` — cargo-deny configuration
+- `cargo-deny.yml` — GitHub Actions CI workflow for dependency auditing
+
+All other files follow upstream conventions.
+
+## Stack
+
+| Layer | Technology |
+|-------|------------|
+| Runtime | tokio (full, rt-multi-thread, macros, sync, fs, process, signal) |
+| HTTP client | reqwest (rustls, hickory-dns, http2) |
+| Auth | aws-config, aws-sdk-bedrockruntime, google-cloud-auth |
+| CLI | clap 4.6 + clap_complete |
+| TUI | reedline 0.47, rustyline 18, termimad, console |
+| Serialization | serde, serde_json, serde_yml, toml_edit |
+| Diff/patch | dissimilar, similar, strip-ansi-escapes |
+| Search | grep-searcher, fzf-wrapped, ignore |
+| MCP | rmcp (client + SSE + subprocess + streamable-http transports) |
+| Observability | tracing, tracing-subscriber, posthog-rs |
+| Git | gix |
+| Misc | anyhow, thiserror, uuid, chrono, url, is_ci |
+
+## Key Commands
+
+```bash
+# Build (from repo root)
+cargo build --release
+
+# Test
+cargo test --workspace
+
+# Format
+cargo fmt --check
+
+# Lint
+cargo clippy --workspace --all-targets -- -D warnings
+
+# Full quality gate
+cargo fmt --check && cargo clippy --workspace --all-targets -- -D warnings && cargo test --workspace
+```
+

+
+## Quality Gates
+
+- `cargo fmt --check` — formatting must pass
+- `cargo clippy --workspace --all-targets -- -D warnings` — zero lints allowed
+- `cargo test --workspace` — all tests must pass
+- `cargo deny check` — dependency audit (configured in `deny.toml`)
+- Snapshot tests via `insta` — review snapshots with `cargo insta review`
+
+## CI / GitHub Actions
+
+- `cargo-deny.yml` runs `cargo deny check advisories licenses` on every PR
+- `deny.toml` defines allowlist rules for crates and licenses
+- Run `cargo deny check` locally before opening PRs
+
+## Git Workflow
+
+```
+origin  = KooshaPari/forgecode     (Phenotype-org fork)
+upstream = tailcallhq/forgecode     (canonical upstream)
+```
+
+Sync from upstream:
+```bash
+git fetch upstream
+git checkout main
+git merge upstream/main
+git push origin main
+```
+
+## Security & Compliance
+
+- `deny.toml` + `cargo-deny.yml` enforce dependency audit (advisories + licenses)
+- `cargo deny check` must pass before merging

-## Quickstart
-
-To get started with Forge, run the command below:
-
-```bash
-curl -fsSL https://forgecode.dev/cli | sh
-```
-
-On first run, Forge will guide you through setting up your AI provider credentials using the interactive login flow. Alternatively, you can configure providers beforehand:
-
-```bash
-# Configure your provider credentials interactively
-forge provider login
-
-# Then start Forge
-forge
-```
-That's it! Forge is now ready to assist you with your development tasks.

-## Why Forge?
-
-Forge is designed for developers who want to enhance their workflow with AI assistance while maintaining full control over their development environment.
-
-- **Zero configuration** - Just add your API key and you're ready to go
-- **Seamless integration** - Works right in your terminal, where you already work
-- **Multi-provider support** - Use OpenAI, Anthropic, or other LLM providers
-- **Secure by design** - Restricted shell mode limits file system access and prevents unintended changes
-- **Open-source** - Transparent, extensible, and community-driven
-
-Forge helps you code faster, solve complex problems, and learn new technologies without leaving your terminal.
-
----
-
-## How Forge Works: Three Modes
-
-Forge has three distinct ways to use it. Understanding this distinction upfront will save you confusion.
-
-### Interactive Mode (TUI)
-
-Running `forge` with no arguments starts the interactive terminal UI, a persistent session where you type prompts and the AI responds in a conversational loop. This is the primary way to do multi-step work.
-
-```bash
-forge                              # Start a new interactive session
-forge conversation resume <id>     # Resume a specific saved conversation in interactive mode
-forge --conversation-id <id>       # Same: resume conversation by ID
-forge --agent <agent-id>           # Start interactive session with a specific agent
-forge -C /path/to/project          # Start in a specific directory
-forge --sandbox experiment-name    # Create an isolated git worktree + branch, then start there
-```
-
-Once inside interactive mode, type your prompt and press Enter. Forge reads files, writes patches, runs commands, and maintains context across the whole session.
-
-### One-Shot CLI Mode
-
-Pass `-p` (or `--prompt`) to run a single prompt and exit. Forge does the work and returns to your shell. Useful for scripts, piping output, or quick tasks.
-
-```bash
-forge -p "Explain the purpose of src/main.rs"
-forge -p "Add error handling to the parse() function in lib.rs"
-echo "What does this do?" | forge    # Pipe input as the prompt
-forge commit                         # Generate an AI commit message and commit (exits when done)
-forge commit --preview               # Generate commit message, print it, then exit
-forge suggest "find large log files" # Translate natural language to a shell command, then exit
-```
-
-> **Note:** `forge conversation resume <id>` opens the interactive TUI. It does **not** just print a message and exit. If you run it and see the cursor waiting, you are inside the interactive session. Type your prompt or press `Ctrl+C` to exit.
-
-### ZSH Plugin Mode (`:` prefix)
-
-Install the ZSH plugin once with `forge setup`, then use `:` commands directly at your shell prompt without ever typing `forge`. This is the fastest mode for day-to-day development: send prompts, switch conversations, commit, and suggest commands without leaving your shell.
-
-```zsh
-: refactor the auth module      # Send a prompt to the active agent
-:commit                         # AI-powered git commit
-:suggest "find large log files" # Translate description → shell command in your buffer
-:conversation                   # Browse saved conversations with interactive picker
-```
-
-See the full [ZSH Plugin reference below](#zsh-plugin-the--prefix-system) for all commands and aliases.
-
----
-
-## ZSH Plugin: The `:` Prefix System
-
-When you install the ZSH plugin (`forge setup`), you get a `:` prefix command system at your shell prompt. This is the fastest way to use Forge during normal development; you never leave your shell.
-
-**How it works:** Lines starting with `:` are intercepted before the shell sees them and routed to Forge. Everything else runs normally.
-
-```zsh
-: <prompt>         # Send a prompt to the active agent
-:sage <prompt>     # Send a prompt to a specific agent by name (sage, muse, forge, or any custom agent)
-:agent <name>      # Switch the active agent; opens interactive picker if no name given
-```
-
-### Agents
-
-Forge ships with three built-in agents, each with a different role:
-
-| Agent | Alias | Purpose | Modifies files? |
-|---|---|---|---|
-| `forge` | (default) | Implementation: builds features, fixes bugs, and runs tests | Yes |
-| `sage` | `:ask` | Research: maps architecture, traces data flow, and reads code | No |
-| `muse` | `:plan` | Planning: analyzes structure and writes implementation plans to `plans/` | No |
-
-### Sending Prompts
-
-```zsh
-: refactor the auth module to use the new middleware
-:sage how does the caching layer work?    # sage = read-only research agent
-:muse design a deployment strategy        # muse = planning agent (writes to plans/)
-:ask how does X work?                     # alias for :sage
-:plan create a migration plan             # alias for :muse
 ```
-
-The agent context persists. Typing `:sage` alone (no prompt text) switches the active agent to sage for all subsequent `: <prompt>` commands.
-
-### Attaching Files
-
-Type `@` in a prompt, then press Tab to fuzzy-search and select files. The path is inserted as `@[filename]` and attached as context to the AI.
-
-```zsh
-: review this code @[src/auth.rs] @[tests/auth_test.rs]
-```
-
-### Conversation Management
-
-Forge saves every conversation. You can switch between them like switching directories.
-
-```zsh
-:new                      # Start a fresh conversation (saves current for :conversation -)
-:new <initial prompt>     # Start a new conversation and immediately send a prompt
-:conversation             # Open interactive picker: browse and switch conversations with preview
-:conversation <id>        # Switch directly to a conversation by ID
-:conversation -           # Toggle between current and previous conversation (like cd -)
-:clone                    # Branch the current conversation (try a different direction)
-:clone <id>               # Clone a specific conversation by ID
-:rename <name>            # Rename the current conversation
-:conversation-rename      # Rename a conversation via interactive picker
-:retry                    # Retry the last prompt (useful if the AI misunderstood)
-:copy                     # Copy the last AI response to clipboard as markdown
-:dump                     # Export conversation as JSON
-:dump html                # Export conversation as formatted HTML
-:compact                  # Manually compact context to free up token budget
-```
-
-### Git Integration
-
-```zsh
-:commit                   # AI reads your diff, writes a commit message, and commits immediately
-:commit <context>         # Same, but pass extra context: :commit fix typo in readme
-:commit-preview           # AI generates the message and puts "git commit -m '...'" in your buffer
-                          # so you can review/edit the message before pressing Enter
-```
-
-### Shell Command Tools
-
-```zsh
-:suggest <description>    # Translate natural language to a shell command and put it in your buffer
-:edit                     # Open $EDITOR to compose a complex multi-line prompt, then send it
-```
-
-### Session & Configuration
-
-Some commands change settings for the current session only. Others persist to your config file (`~/forge/.forge.toml`). The distinction matters:
-
-```zsh
-# Session-only (reset when you close the terminal; not saved to config)
-:model <model-id>              # Change model for this session only
-:reasoning-effort <level>      # Set reasoning effort: none/minimal/low/medium/high/xhigh/max
-:agent <id>                    # Switch active agent for this session
-
-# Persistent (saved to config file)
-:config-model <model-id>       # Set default model globally  (alias: :cm)
-:config-provider               # Switch provider globally    (alias: :provider, :p)
-:config-reasoning-effort <lvl> # Set default reasoning effort globally (alias: :cre)
-:config-commit-model <id>      # Set model used for :commit  (alias: :ccm)
-:config-suggest-model <id>     # Set model used for :suggest (alias: :csm)
-:config-reload                 # Reset session overrides back to global config (alias: :cr)
-
-# View & edit config
-:info                          # Show current session info (model, agent, conversation ID)
-:config                        # Display effective resolved configuration in TOML format
-:config-edit                   # Open config file in $EDITOR (alias: :ce)
-:tools                         # List available tools for the current agent
-:skill                         # List available skills
-```
-
-### Skills
-
-Skills are reusable workflows the AI can invoke as tools. Forge ships three built-in skills:
-
-- **`create-skill`**: scaffold a new custom skill
-- **`execute-plan`**: execute a plan file from `plans/`
-- **`github-pr-description`**: generate a PR description from your diff
-
-Use `:skill` to list available skills. The AI invokes them automatically when relevant, or you can ask explicitly: `: generate a PR description using the github-pr-description skill`.
-
-**Custom skills** live in `SKILL.md` files with YAML front-matter. Precedence (highest first):
-
-| Location | Path | Scope |
-|---|---|---|
-| Project-local | `.forge/skills/<name>/SKILL.md` | This project only |
-| Global | `~/forge/skills/<name>/SKILL.md` | All projects |
-| Built-in | Embedded in binary | Always available |
-
-Project-local skills override global ones, which override built-in ones. To scaffold a new skill, ask: `: create a new skill`.
-
-### Customizing Agent Behavior
-
-**`AGENTS.md`:** Create this file in your project root (or `~/forge/AGENTS.md` globally) to give all agents persistent instructions such as coding conventions, commit message style, and things to avoid. Forge reads it automatically at the start of every conversation.
-
-**Custom agents:** Place a `.md` file with YAML front-matter in `.forge/agents/` (project) or `~/forge/agents/` (global) to define additional agents with their own models, tools, and system prompts. Project-local agents override global ones. The built-in agent files in `crates/forge_repo/src/agents/` are good examples of the format.
-
-**Custom commands:** Place YAML files in `.forge/commands/` (project) or `~/forge/commands/` (global) to define shortcut commands available via `:commandname`. Commands can also be defined inline in `forge.yaml` under the `commands:` key.
-
-### Semantic Search (Workspace)
-
-```zsh
-:sync                     # Index your codebase for semantic search
-:workspace-init           # Initialize workspace for indexing
-:workspace-status         # Show indexing status
-:workspace-info           # Show workspace details
-```
-
-After running `:sync`, the AI can search your codebase by meaning rather than exact text matches. Indexing sends file content to the workspace server, which defaults to `https://api.forgecode.dev`. Set `FORGE_WORKSPACE_SERVER_URL` to override this if self-hosting.

-
-## Advanced Configuration
-
-### Provider Configuration
-
-Forge supports multiple AI providers. The recommended way to configure providers is using the interactive login command:
-
-```bash
-forge provider login
-```
-
-This will:
-
-1. Show you a list of available providers
-2. Guide you through entering the required credentials
-
-#### Managing Provider Credentials
-
-```bash
-# Login to a provider (add or update credentials)
-forge provider login
-
-# Remove provider credentials
-forge provider logout
-
-# List supported providers
-forge provider list
-```
-
-#### Deprecated: Environment Variables
-
-> **⚠️ DEPRECATED**: Using `.env` files for provider configuration is deprecated and will be removed in a future version. Please use `forge provider login` instead.
-
-For backward compatibility, Forge still supports environment variables. On first run, any credentials found in environment variables will be automatically migrated to file-based storage.

-
-### Environment Variables
-
-Forge supports several environment variables for advanced configuration and fine-tuning. These can be set in your `.env` file or system environment.
-
-<details>
-<summary><strong>Retry Configuration</strong></summary>
-
-Control how Forge handles retry logic for failed requests:
-
-```bash
-# .env
-FORGE_RETRY_INITIAL_BACKOFF_MS=1000    # Initial backoff time in milliseconds (default: 1000)
-FORGE_RETRY_BACKOFF_FACTOR=2           # Multiplier for backoff time (default: 2)
-FORGE_RETRY_MAX_ATTEMPTS=3             # Maximum retry attempts (default: 3)
-FORGE_SUPPRESS_RETRY_ERRORS=false      # Suppress retry error messages (default: false)
-FORGE_RETRY_STATUS_CODES=429,500,502   # HTTP status codes to retry (default: 429,500,502,503,504)
-```
-
-</details>
-
-<details>
-<summary><strong>HTTP Configuration</strong></summary>
-
-Fine-tune HTTP client behavior for API requests:
-
-```bash
-# .env
-FORGE_HTTP_CONNECT_TIMEOUT=30              # Connection timeout in seconds (default: 30)
-FORGE_HTTP_READ_TIMEOUT=900                # Read timeout in seconds (default: 900)
-FORGE_HTTP_POOL_IDLE_TIMEOUT=90            # Pool idle timeout in seconds (default: 90)
-FORGE_HTTP_POOL_MAX_IDLE_PER_HOST=5        # Max idle connections per host (default: 5)
-FORGE_HTTP_MAX_REDIRECTS=10                # Maximum redirects to follow (default: 10)
-FORGE_HTTP_USE_HICKORY=false               # Use Hickory DNS resolver (default: false)
-FORGE_HTTP_TLS_BACKEND=default             # TLS backend: "default" or "rustls" (default: "default")
-FORGE_HTTP_MIN_TLS_VERSION=1.2             # Minimum TLS version: "1.0", "1.1", "1.2", "1.3"
-FORGE_HTTP_MAX_TLS_VERSION=1.3             # Maximum TLS version: "1.0", "1.1", "1.2", "1.3"
-FORGE_HTTP_ADAPTIVE_WINDOW=true            # Enable HTTP/2 adaptive window (default: true)
-FORGE_HTTP_KEEP_ALIVE_INTERVAL=60          # Keep-alive interval in seconds (default: 60, use "none"/"disabled" to disable)
-FORGE_HTTP_KEEP_ALIVE_TIMEOUT=10           # Keep-alive timeout in seconds (default: 10)
-FORGE_HTTP_KEEP_ALIVE_WHILE_IDLE=true      # Keep-alive while idle (default: true)
-FORGE_HTTP_ACCEPT_INVALID_CERTS=false      # Accept invalid certificates (default: false) - USE WITH CAUTION
-FORGE_HTTP_ROOT_CERT_PATHS=/path/to/cert1.pem,/path/to/cert2.crt  # Paths to root certificate files (PEM, CRT, CER format), multiple paths separated by commas
-```
-
-> **⚠️ Security Warning**: Setting `FORGE_HTTP_ACCEPT_INVALID_CERTS=true` disables SSL/TLS certificate verification, which can expose you to man-in-the-middle attacks. Only use this in development environments or when you fully trust the network and endpoints.

-<summary><strong>ZSH Plugin Configuration</strong></summary>
-
-Configure the ZSH plugin behavior:
-
-```bash
-# .env
-FORGE_BIN=forge                    # Command to use for forge operations (default: "forge")
-```
-
-The `FORGE_BIN` environment variable allows you to customize the command used by the ZSH plugin when transforming `:` prefixed commands. If not set, it defaults to `"forge"`.
-
-</details>
-
-<details>
-<summary><strong>Display Configuration</strong></summary>
-
-Configure display options for the Forge UI and ZSH theme:
-
-```bash
-# .env
-FORGE_CURRENCY_SYMBOL="$"         # Currency symbol for cost display in ZSH theme (default: "$")
-FORGE_CURRENCY_CONVERSION_RATE=1.0  # Conversion rate for currency display (default: 1.0)
-NERD_FONT=1                       # Enable Nerd Font icons in ZSH theme (default: auto-detected, set to "1" or "true" to enable, "0" or "false" to disable)
-USE_NERD_FONT=1                   # Alternative variable for enabling Nerd Font icons (same behavior as NERD_FONT)
-```
-
-The `FORGE_CURRENCY_SYMBOL` and `FORGE_CURRENCY_CONVERSION_RATE` variables control how costs are displayed in the ZSH theme right prompt. Use these to customize the currency display for your region or preferred currency.
-
-</details>
-
-<details>
-<summary><strong>System Configuration</strong></summary>
-
-System-level environment variables (usually set automatically):
-
-```bash
-# .env
-FORGE_CONFIG=/custom/config/dir        # Base directory for all Forge config files (default: ~/.forge)
-FORGE_MAX_SEARCH_RESULT_BYTES=10240   # Maximum bytes for search results (default: 10240 - 10 KB)
-FORGE_HISTORY_FILE=/path/to/history    # Custom path for Forge history file (default: uses system default location)
-FORGE_BANNER="Your custom banner text" # Custom banner text to display on startup (default: Forge ASCII art)
-FORGE_MAX_CONVERSATIONS=100            # Maximum number of conversations to show in list (default: 100)
-FORGE_MAX_LINE_LENGTH=2000             # Maximum characters per line for file read operations (default: 2000)
-FORGE_STDOUT_MAX_LINE_LENGTH=2000      # Maximum characters per line for shell output (default: 2000)
-SHELL=/bin/zsh                         # Shell to use for command execution (Unix/Linux/macOS)
-COMSPEC=cmd.exe                        # Command processor to use (Windows)
-```
-
-</details>
-
-<details>
-<summary><strong>Semantic Search Configuration</strong></summary>
-
-Configure semantic search behavior for code understanding:
-
-```bash
-# .env
-FORGE_SEM_SEARCH_LIMIT=200            # Maximum number of results to return from initial vector search (default: 200)
-FORGE_SEM_SEARCH_TOP_K=20             # Top-k parameter for relevance filtering during semantic search (default: 20)
-```
-
-</details>
-
-<details>
-<summary><strong>Logging Configuration</strong></summary>
-
-Configure logging verbosity and output:
-
-```bash
-# .env
-FORGE_LOG=forge=info                  # Log filter level (default: forge=debug when tracking disabled, forge=info when tracking enabled)
-```
-
-The `FORGE_LOG` variable controls the logging level for Forge's internal operations using the standard tracing filter syntax. Common values:
-- `forge=error` - Only errors
-- `forge=warn` - Warnings and errors
-- `forge=info` - Informational messages (default when tracking enabled)
-- `forge=debug` - Debug information (default when tracking disabled)
-- `forge=trace` - Detailed tracing
-
-</details>
-
-<details>
-<summary><strong>Tracking Configuration</strong></summary>
-
-Control tracking of user-identifying metadata in telemetry events:
-
-```bash
-# .env
-FORGE_TRACKER=false                   # Disable tracking enrichment metadata (default: true)
-```
-
-The `FORGE_TRACKER` variable controls whether tracking enrichment metadata is included in telemetry events.
-
-</details>
-
-The `forge.yaml` file supports several advanced configuration options that let you customize Forge's behavior.
-
-<details>
-<summary><strong>Custom Rules</strong></summary>
-
-Add your own guidelines that all agents should follow when generating responses.
-
-```yaml
-# forge.yaml
-custom_rules: |
-  1. Always add comprehensive error handling to any code you write.
-  2. Include unit tests for all new functions.
-  3. Follow our team's naming convention: camelCase for variables, PascalCase for classes.
-```
-
-</details>
-
-<details>
-<summary><strong>Commands</strong></summary>
-
-Define custom commands as shortcuts for repetitive prompts:
-
-```yaml
-# forge.yaml
-commands:
-  - name: "refactor"
-    description: "Refactor selected code"
-    prompt: "Please refactor this code to improve readability and performance"
-```
-
-</details>
-
-<details>
-<summary><strong>Model</strong></summary>
-
-Specify the default AI model to use for all agents in the workflow.
-
-```yaml
-# forge.yaml
-model: "claude-3.7-sonnet"
-```
-
-</details>
-
-<details>
-<summary><strong>Max Walker Depth</strong></summary>
-
-Control how deeply Forge traverses your project directory structure when gathering context.
-
-```yaml
-# forge.yaml
-max_walker_depth: 3 # Limit directory traversal to 3 levels deep
-```
-
-</details>
-
-<details>
-<summary><strong>Temperature</strong></summary>
-
-Adjust the creativity and randomness in AI responses. Lower values (0.0-0.3) produce more focused, deterministic outputs, while higher values (0.7-2.0) generate more diverse and creative results.
-
-```yaml
-# forge.yaml
-temperature: 0.7 # Balanced creativity and focus
-```
-
-</details>
-<details>
-<summary><strong>Tool Max Failure Limit</strong></summary>
-
-Control how many times a tool can fail before Forge forces completion to prevent infinite retry loops. This helps avoid situations where an agent gets stuck repeatedly trying the same failing operation.
-
-```yaml
-# forge.yaml
-max_tool_failure_per_turn: 3 # Allow up to 3 failures per tool before forcing completion
-```
-
-Set to a higher value if you want more retry attempts, or lower if you want faster failure detection.
-
-</details>
-
-<details>
-<summary><strong>Max Requests Per Turn</strong></summary>
-
-Limit the maximum number of requests an agent can make in a single conversation turn. This prevents runaway conversations and helps control API usage and costs.
-
-```yaml
-# forge.yaml
-max_requests_per_turn: 50 # Allow up to 50 requests per turn
-```
-
-When this limit is reached, Forge will:
-
-- Ask you if you wish to continue
-- If you respond with 'Yes', it will continue the conversation
-- If you respond with 'No', it will end the conversation
-
-</details>

-<summary><strong>Model Context Protocol (MCP)</strong></summary>
-
-The MCP feature allows AI agents to communicate with external tools and services. This implementation follows Anthropic's [Model Context Protocol](https://docs.anthropic.com/en/docs/claude-code/tutorials#set-up-model-context-protocol-mcp) design.
-
-### MCP Configuration
-
-Configure MCP servers using the CLI:
-
-```bash
-# List all MCP servers
-forge mcp list
-
-# Import a server from JSON
-forge mcp import
-
-# Show server configuration details
-forge mcp show
-
-# Remove a server
-forge mcp remove
-
-# Reload servers and rebuild caches
-forge mcp reload
-```
-
-Or manually create a `.mcp.json` file with the following structure:
-
-```json
-{
-  "mcpServers": {
-    "server_name": {
-      "command": "command_to_execute",
-      "args": ["arg1", "arg2"],
-      "env": { "ENV_VAR": "value" }
-    },
-    "another_server": {
-      "url": "http://localhost:3000/events"
-    }
-  }
-}
-```
-
-MCP configurations are read from two locations (project-local takes precedence):
-
-1. **Project-local:** `.mcp.json` in your project directory
-2. **Global:** `~/forge/.mcp.json`
-
-### Example Use Cases
-
-MCP can be used for various integrations:
-
-- Web browser automation
-- External API interactions
-- Tool integration
-- Custom service connections
-
-### Usage in Multi-Agent Workflows
-
-MCP tools can be used as part of multi-agent workflows, allowing specialized agents to interact with external systems as part of a collaborative problem-solving approach.

+//! Daemon PID file + advisory flock.
+//!
+//! The PID file lives at `~/.forge/daemon.pid` (or whatever the caller passes
+//! to [`PidFile::acquire`]) and serves two purposes:
+//!
+//! 1. **Discovery** — clients can resolve the running daemon by reading the
+//!    PID and asking `/proc/<pid>/` whether it's still alive before
+//!    connecting to the Unix socket. The PID file alone does not guarantee
+//!    exclusivity: if a daemon is killed with `kill -9` and a new one starts
+//!    before the stale PID is cleaned up, both could race.
+//!
+//! 2. **Advisory exclusion** — for the brief interval between
+//!    "daemon A is shutting down" and "kernel has reaped A", the PID file
+//!    acts as a hint that something *recently* held the slot. Pairing it with
+//!    `flock(2)` on the same fd (or a sibling `daemon.lock` file) gives a
+//!    stronger guarantee: the kernel-level lock survives process death
+//!    without coordination.
+//!
+//! Design choice: we use [`fs2::FileExt`] for `flock(2)` (cross-platform,
+//! no tokio dep) and use a separate `lock` file from the pid file so that
+//! external tooling can inspect the pid without taking the lock.
+//!
+//! Failure modes:
+//! - If the lock can be acquired but the pid file is unparseable, we
+//!   overwrite the pid file (the holder is gone). This means a crash-then-
+//!   restart cycle works without manual cleanup.
+//! - If the lock is held *and* the recorded pid is alive, we return
+//!   [`Forge3Error::LockHeld`] with the live pid so the caller can
+//!   decide whether to wait, error out, or take over.

+# forge_dbd — WIP
+
+> **Status: Work In Progress — not yet wired into the main application.**
+
+SQLite daemon crate for persistent conversation storage. Intended as a background
+IPC daemon that serialises conversation history to a local SQLite database.
+
+## Current state
+
+- Protocol types defined (`protocol.rs`)
+- Stub server + client skeletons (`server.rs`, `client.rs`)
+- Binary entry point exists (`main.rs`)
+- **Not depended upon by any other workspace crate**
+- **Not included in the shipped binary**
+
+## Planned integration
+
+Part of the SQLite-WAL/FTS epic. Will be wired into `forge_app` once the IPC
+contract is finalised. Do not ship or enable without completing that epic.

+//! Resilience primitives: circuit breaker and concurrency bulkhead.

+//! # Circuit breaker
+//!
+//! Wraps call sites that can fail transiently (MCP servers, provider HTTP
+//! endpoints). After `failure_threshold` consecutive failures the breaker
+//! **opens** and every call fails immediately with [`CircuitOpenError`].
+//! After `reset_timeout` the breaker enters a **half-open** probe: the next
+//! call is allowed through.  On success the breaker **closes** again; on
+//! failure it re-opens and the timer resets.
+//!
+//! All state is held behind an `Arc<Mutex<…>>` so the breaker can be cloned
+//! cheaply and shared across tasks.
+//!
+//! # Bulkhead
+//!
+//! A thin wrapper around [`tokio::sync::Semaphore`] that bounds how many
+//! concurrent calls reach the protected resource.  When the semaphore is
+//! exhausted the caller receives [`BulkheadFullError`] immediately (no
+//! queue-and-wait semantics — this is intentional: callers must be aware that
+//! the downstream is saturated).

+//! # forge_pheno_shell
+//!
+//! Shell abstraction layer for forgecode (per ADR-101 §4.1, ADR-096 fleet pattern).
+//!
+//! Detects the user's shell, emits shell-specific completion scripts, and routes
+//! environment setup per shell. Supports:
+//!
+//! - **POSIX**: ZSH, Bash, Fish, Tcsh, Oil, Elvish, Nushell
+//! - **Windows-native**: PowerShell (Windows), PowerShell Core (cross-platform), Cmd
+//! - **Emulator shells**: WSL Bash (Windows -> Linux), Git Bash (Windows)
+//!
+//! This crate is intentionally **zero dependency on `forge_domain`** (ADR-097 decoupling
+//! pattern). It is pure-Rust, framework-agnostic, and consumable from any forgecode crate.

+//! forge_pheno_winterminal — Windows Terminal profile/palette/scheme management
+//!
+//! Manages Windows Terminal `profiles.json` (profiles, color schemes, font faces,
+//! cursor shapes, padding, acrylic opacity) programmatically so forgecode can
+//! switch terminal themes, tie profiles to agent identities, and sync Ghostty
+//! config to Windows Terminal.
+//!
+//! ## Architecture
+//!
+//! ```text
+//! WinterminalConfig
+//!   ├── profiles: Vec<Profile>     (terminal instances)
+//!   ├── schemes: Vec<Scheme>      (color schemes)
+//!   ├── actions: Vec<Action>      (key bindings)
+//!   ├── default_profile: String   (guid)
+//!   └── global: GlobalSettings    (alwaysOnTop, tabWidthMode, etc.)
+//!
+//! Profile
+//!   ├── guid, name, icon
+//!   ├── font: FontConfig          (face, size, weight, features)
+//!   ├── cursor: CursorConfig      (shape, height, color)
+//!   ├── background: BackgroundConfig  (image, opacity, acrylic)
+//!   └── color_scheme: String      (ref to Scheme.name)
+//!
+//! Scheme
+//!   ├── name
+//!   ├── foreground, background, selectionBackground, cursorColor
+//!   ├── black, red, green, yellow, blue, magenta, cyan, white
+//!   └── brightBlack … brightWhite, dimBlack … dimWhite
+//! ```
+//!
+//! ## Key design decisions
+//!
+//! - **No_std guard**: `profiles.json` is the single source of truth on disk.
+//!   `WinterminalConfig::load()` / `save()` are the only mutation entry points.
+//! - **Idempotent merge**: `apply_theme()` calls `upsert_profile()` + `upsert_scheme()`
+//!   in a single write transaction (atomic write + backup).
+//! - **Cross-platform detection**: `detect_install()` returns `InstallState` even on
+//!   non-Windows hosts (reports `NotInstalled(Reason::NotWindows)`); all API calls
+//!   short-circuit on non-Windows.

+//! Phenotype-org addition for WAL contention control and incremental vacuum in a shared `.forge.db`.
+//!
+//! Many forge processes can point at the same SQLite database file. Per-connection
+//! passive autocheckpointing tends to no-op under contention because readers or
+//! writers often keep frames pinned, but every writer still pays the checkpoint
+//! attempt cost. This module dedicates one background thread per process to
+//! periodically probe the WAL and truncate it when it is large enough to matter.
+//!
+//! After each checkpoint, if enabled via `FORGE_INCREMENTAL_VACUUM` (default: enabled),
+//! it also runs `PRAGMA incremental_vacuum` to return freed pages (from P4 prune, zstd
+//! compression, deletes) to the OS without an exclusive-lock full VACUUM.
+//!
+//! SQLite serialises checkpoints and vacuums across processes, so only one process will
+//! successfully truncate/vacuum at a time while the others observe `busy` and skip.
+//! That means we do not need process-wide election or coordination: each process
+//! can own one best-effort checkpointer, and the database file will still be
+//! reclaimed safely.

+--
+-- The base conversations.context is still compressed (zstd on disk), so the PRIMARY
+-- savings remain. The FTS _content copy is searchable but does not further compress.
+-- This is pragmatic: FTS5 CONTENTFUL is the simplest correct design.
+
+-- Drop the broken external-content FTS5 table
+DROP TABLE IF EXISTS conversations_fts;
+

+CREATE VIRTUAL TABLE conversations_fts USING fts5(

+    cwd,

+);
+
+-- Table is created EMPTY. Application-side refresh_fts_index will populate it
+-- with decompressed context from both compressed and uncompressed rows.

+# SSOT — forgecode
+
+Authoritative state-of-the-repo. forgecode is an AI-enhanced terminal development environment (agentic coding CLI/TUI), a Rust Cargo workspace, fork of [tailcallhq/forgecode](https://github.com/tailcallhq/forgecode).
+
+## State
+- Default branch: main
+- Last verified: 2026-06-28
+- Binary: `forge` (crates/forge_main, v2.10.0)
+- CI status: green
+
+## Dependencies
+- Rust: 2021 edition (Cargo workspace, 33 crates)
+- Node: N/A (no JS/TS product code)
+- Python: tooling-only (governance propagation scripts)
+
+## Architecture
+- Pattern: hexagonal (ports-and-adapters)
+- Domain (pure, framework-free): `forge_domain` — models + traits/ports
+- Composition root: `forge_app` wires `forge_services` + adapters into the domain
+- Public API boundary: `forge_api` (the async-trait `API`)
+- Adapters: `forge_infra` (env/fs/process/http), `forge_repo` (persistence + provider repos: OpenAI, Anthropic, …)
+- Persistence: SQLite via Diesel + r2d2 pool (WAL mode, busy_timeout, dedicated checkpointer); `forge_dbd` session daemon (WIP)
+- Streaming: `forge_stream`, `forge_eventsource`, `forge_markdown_stream`
+- TUI/render: `forge_display`, `forge_select`, `forge_spinner`, `forge_snaps`, `forge_template`
+
+## Fork-specific features (this fork vs upstream)
+- SQLite session store: WAL checkpointing, zstd context compression, incremental auto_vacuum
+- Conversation FTS5 + vector search; sort/filter wired into the TUI conv-view
+- Subagent breadcrumbs ("spawned by X") in the info panel / conv header
+
+## Next Steps (DAG)
+See `docs/sessions/20260628-forgecode-overhaul/03_DAG_WBS.md` for the active phased overhaul roadmap (P0 de-fork docs → P1 CI gates/stubs/security → P2 resilience/observability/lifecycle → P3 perf/concurrency → P4 ops/threat-model → P5 cross-repo shared crates).

+# ADR-0001: Compaction Summarization Strategy
+
+**Date:** 2026-05-02
+**Status:** Accepted
+**Deciders:** Forgecode Team
+
+---
+
+## Context
+
+The forgecode context compaction system currently uses pure structural extraction to summarize conversations. This approach:
+
+- Extracts tool calls, tool results, file paths, and commands
+- Renders into a markdown template (`forge-partial-summary-frame.md`)
+- Is fast (~0ms), deterministic, and cost-free
+
+However, this approach has limitations:
+1. **Low semantic fidelity** — captures structure, not meaning
+2. **No understanding of decisions** — can't capture why changes were made
+3. **Verbose output** — includes all operations, even low-value ones
+4. **No prioritization** — treats all content equally
+
+As forgecode grows more capable and handles complex multi-step tasks, the quality of context summarization directly impacts downstream task performance.
+
+---
+
+## Decision
+
+We will implement a **hybrid summarization strategy** with three modes:
+
+```rust
+pub enum SummarizationStrategy {
+    /// Pure structural extraction (current behavior)
+    Extract,
+
+    /// LLM-based semantic summarization
+    Llm,
+
+    /// Hybrid: extract first, then refine with LLM
+    Hybrid,
+}
+```
+
+**Default:** `Extract` (backward compatible)
+**Configuration:** Per-agent via `compact.summarization_strategy`
+
+---
+
+## Rationale
+
+### Why not pure LLM?
+
+- **Latency**: LLM summarization adds 500ms-2s per compaction
+- **Cost**: Per-token API costs accumulate with frequent compaction
+- **Determinism**: Same input may produce different outputs
+- **Complexity**: Requires error handling for API failures
+
+### Why not pure extraction?
+
+- **Semantic fidelity**: Can't capture decision rationale
+- **Noise**: Includes low-value operations
+- **Quality ceiling**: Limited improvement potential
+
+### Why hybrid?
+
+- **Best of both**: Fast extraction with LLM refinement
+- **Progressive enhancement**: Users can opt into higher quality
+- **Fallback safety**: Extract always available as fallback
+- **Cost control**: Use cheaper models for summarization
+
+---
+
+## Implementation Options
+
+### Option A: Extract-Only (Status Quo)
+
+**Pros:**
+- Fastest (~0ms)
+- Zero API cost
+- Fully deterministic
+- No API failure modes
+
+**Cons:**
+- Low semantic fidelity
+- Verbose summaries
+- No decision capture
+
+### Option B: Pure LLM
+
+**Pros:**
+- Highest semantic fidelity
+- Captures decisions and rationale
+- Can identify important context
+
+**Cons:**
+- ~500ms-2s latency per compaction
+- Per-token API cost
+- Non-deterministic output
+- API failure handling required
+
+### Option C: Hybrid (Selected)
+
+**Pros:**
+- Balance of speed and quality
+- Can use cheap models (haiku)
+- Structured data from extraction + semantics from LLM
+- Fallback to extract on failure
+
+**Cons:**
+- More complex implementation
+- Two-step process adds some latency
+- Requires LLM integration
+
+### Option D: Adaptive Cascade
+
+**Pros:**
+- Automatically chooses strategy based on complexity
+- Best resource allocation
+- Can escalate as needed
+
+**Cons:**
+- Most complex implementation
+- Harder to reason about behavior
+- More configuration surface
+
+---
+
+## Decision Outcome
+
+We select **Option C (Hybrid)** as the default for enhanced compaction, with:
+
+1. **Extract as default** for backward compatibility
+2. **Hybrid mode** as the recommended upgrade path
+3. **LLM-only** available as opt-in for users who prioritize quality over speed
+4. **Configurable model** for summarization (default: haiku-3.5)
+5. **Timeout protection** (3s max for LLM operations)
+6. **Fallback to extract** on any LLM failure
+
+---
+
+## Consequences
+
+### Positive
+
+- [x] Improved summary quality when enabled
+- [x] Backward compatible with existing configurations
+- [x] Users can choose their cost/quality tradeoff
+- [x] Can use cheap models for summarization
+- [x] Fallback ensures reliability
+
+### Negative
+
+- [ ] Adds complexity to Compactor implementation
+- [ ] Requires LLM provider integration in forge_app
+- [ ] Template engine needs enhancement for new formats
+
+### Neutral
+
+- [ ] New configuration options added (non-breaking)
+- [ ] Metrics collection added for observability
+- [ ] History tracking for incremental summarization
+
+---
+
+## Configuration
+
+```yaml
+# forge.toml
+[compact]
+enabled = true
+token_threshold = 100_000
+eviction_window = 0.2
+
+# NEW: Summarization configuration
+summarization_strategy = "hybrid"  # extract | llm | hybrid
+summary_model = "claude-3-5-haiku"  # cheaper model for summarization
+summary_max_tokens = 4000
+summary_timeout_secs = 3
+```
+
+---
+
+## Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|------------|--------|------------|
+| LLM adds latency | High | Medium | Use cheap model, timeout, cache summaries |
+| LLM quality inconsistent | Medium | High | Validate format, fallback to extract |
+| API failures | Low | Medium | Graceful fallback to extract |
+| Cost accumulation | Medium | Medium | Per-compaction budget, cheap models |
+

+# Provider-Model Contract
+
+**Version:** 1.0.0
+**Status:** Vendored pin — CANONICAL SSOT is `KooshaPari/phenotype-contracts`.
+
+## Canonical Home
+
+> **The authoritative source for these schemas is
+> [KooshaPari/phenotype-contracts](https://github.com/KooshaPari/phenotype-contracts).**
+>
+> The copies in this directory (`docs/contracts/provider-models/`) are a **vendored pin**
+> of that SSOT. Do not edit them here; open a PR against `phenotype-contracts` instead
+> and then re-vendor the updated files.
+
+**Pinned ref:** `cc8f34ed34a3f1ae2ba7edd6810a902e51738693`
+(phenotype-contracts `main` HEAD at time of pin — 2026-06-28)
+
+---
+
+## Purpose
+
+This directory contains the language-agnostic contract for the provider/model registry
+surface shared across three KooshaPari repos that independently implement the same domain:
+
+| Repo | Language | Role |
+|------|----------|------|
+| forgecode | Rust | CLI coding agent — reference implementation |
+| OmniRoute | TypeScript | LLM router / proxy |
+| cliproxy | Go | CLI auth proxy |
+
+All three implement `Provider → Models → Capabilities` and the same SSE/OAuth stop rules.
+Rather than a single shared binary (impossible across Rust/TS/Go without FFI/WASM overhead),
+the contract is a **JSON Schema** that each repo aligns its native types against.
+
+## Files
+
+| File | Description |
+|------|-------------|
+| `provider-model.schema.json` | JSON Schema 2020-12 for `Model`, `ProviderConfig`, `SseStopRule`, `OAuthRefreshPolicy` |
+| `oauth-refresh-policy.schema.json` | JSON Schema 2020-12 for OAuth token refresh timing contract |
+| `resilience-policy.schema.json` | JSON Schema 2020-12 for retry/backoff parameters and retryable-error taxonomy |
+| `README.md` | This file |
+
+## How to use this contract
+
+### forgecode (Rust)
+
+`forge_domain::Model` and `forge_domain::Provider` are the reference implementation.
+`forge_eventsource::is_sse_terminal` is the reference implementation of `SseStopRule`.
+When the domain types change, update the schema to stay in sync.
+
+A conformance test in `crates/forge_eventsource/tests/contract_conformance.rs` asserts
+that forgecode's runtime constants match the contract values declared in these schemas.
+Run it with `cargo test contract_conformance`.
+
+### OmniRoute (TypeScript)
+
+Optionally codegen TypeScript types via:
+
+```bash
+npx json-schema-to-typescript provider-model.schema.json -o src/types/provider-model.d.ts
+```
+
+Align `src/lib/modelCapabilities.ts`, `src/lib/sseTextTransform.ts`, and
+`src/lib/tokenHealthCheck.ts` against the schema semantics (field names, enum values,
+`is_sse_terminal` logic, and `TOKEN_EXPIRY_BUFFER`).
+
+### cliproxy (Go)
+
+Optionally codegen Go structs via:
+
+```bash
+go-jsonschema -p registry provider-model.schema.json -o pkg/llmproxy/registry/provider_model_gen.go
+```
+
+Align `pkg/llmproxy/registry/model_registry.go` field names and capability enums to the schema.
+Per-provider `RefreshLead()` overrides (e.g. codebuddy 24 h) are valid because the
+`oauth_refresh_policy.default_refresh_lead_seconds` field is explicitly *parameterized*.
+
+## SSE terminal-marker rules (normative)
+
+Implementations MUST treat the following SSE event data values as end-of-stream:
+
+- `[DONE]` — the canonical OpenAI/Anthropic sentinel
+- `""` (empty string) — keepalive / implicit close
+
+Additionally:
+- OpenAI: `choices[0].finish_reason` in `{stop, length, content_filter, tool_calls}` signals model completion.
+- Anthropic: `stop_reason` / `message_delta.stop_reason` fields signal model completion.
+- **Synthetic `[DONE]` on silent close:** when the upstream connection closes without an
+  explicit terminal event, implementations MUST emit a synthetic terminal signal rather
+  than propagating an unexpected EOF to callers.
+
+See `forge_eventsource::is_sse_terminal` for the canonical Rust implementation.
+
+## OAuth refresh policy (normative)
+
+A token needs refresh when:
+
+```
+now + refresh_lead >= token.expires_at
+```
+
+Default `refresh_lead` is **300 seconds (5 minutes)**, matching:
+- forgecode: `OAUTH_REFRESH_LEAD = chrono::Duration::minutes(5)` (`forge_services::provider_auth`)
+- OmniRoute: `TOKEN_EXPIRY_BUFFER = 5 * 60 * 1000`
+- cliproxy: `5 * time.Minute` (most providers)
+
+Per-provider overrides are valid (e.g. cliproxy codebuddy uses 86400 s).
+The contract requires the lead to be *parameterized*, not hardcoded.
+
+## Retryable HTTP status codes (normative)
+
+The following HTTP status codes MUST trigger a retry (source: `resilience-policy.schema.json`):
+
+`408, 429, 500, 502, 503, 504, 520, 522, 524, 529`
+
+forgecode reference: `forge_config::RetryConfig` default `status_codes`.
+
+## Re-vendoring
+
+When `KooshaPari/phenotype-contracts` merges a schema change:
+
+1. Copy the updated `*.schema.json` files here.
+2. Update the **Pinned ref** SHA at the top of this README.
+3. Run `cargo test contract_conformance` to verify forgecode's constants still match.
+4. Commit with message `chore(contracts): re-vendor phenotype-contracts@<sha>`.
+
+## Versioning
+
+Contract changes follow semver:
+- **Patch** — clarifications, description-only updates, no field changes.
+- **Minor** — new optional fields; existing fields unchanged.
+- **Major** — field renames, type changes, or removal of fields.

+# forgecode — Intent
+
+forgecode is a registered phenotype-* repository. This is a stub intent file
+generated on 2026-06-21 by `scripts/render-stubs.py`. It exists because
+`ECOSYSTEM_MAP.md` declares forgecode canonical but no curated prompts
+have been generated for it yet during the L7 sweep.

+# ForgeCode Runbook
+
+> Status: Living document. Owner: ForgeCode maintainers.
+> Last reviewed: 2026-06-28 (Phase P4 overhaul).
+> Audience: end users and maintainers diagnosing a misbehaving local install.
+
+ForgeCode is a local tool, so "operations" means **diagnosing one machine**.
+Each entry below has: symptoms, likely cause, diagnosis, and fix. State paths
+referenced live under `~/.forge/`.
+
+Key local artifacts:
+
+- `~/.forge/forge.db` — SQLite conversation store (daemon).
+- `~/.forge/.forge.db.sock` — Unix domain socket for `forge_dbd`
+  (`crates/forge_dbd/src/main.rs:15-23`).
+- `~/.forge/.credentials.json` — provider credentials (mode 0o600).
+- `~/.forge/.mcp-credentials.json` — MCP OAuth state (mode 0o600).
+- `.mcp.json` — MCP server configuration.
+
+---
+
+## 1. Database locked / conversation writes failing
+
+**Symptoms:** conversation history not persisting; errors mentioning the
+database being busy/locked; daemon log shows write failures.
+
+**Likely cause:** Two `forge_dbd` instances bound to the same DB, a stale lock
+from a crashed daemon, or a WAL that needs checkpointing.
+
+**Diagnosis:**
+
+1. Check whether more than one daemon is running:
+   `ps aux | grep forge_dbd`
+2. Check the socket exists and is fresh: `ls -la ~/.forge/.forge.db.sock`
+3. Confirm reachability with a health probe (see §2).
+
+**Fix:**
+
+1. Stop extra daemon instances (leave one).
+2. The daemon removes a stale socket before binding
+   (`crates/forge_dbd/src/server.rs:75-78`); if a stale socket persists after a
+   hard crash, remove it manually: `rm ~/.forge/.forge.db.sock`, then restart
+   the daemon.
+3. If WAL growth is the issue, the daemon supports `Request::CheckpointWal`
+   (`crates/forge_dbd/src/protocol.rs`); trigger a checkpoint, or restart the
+   daemon to flush.
+4. **Last resort** — back up `~/.forge/forge.db`, then move it aside and let the
+   daemon recreate it. *Never* delete it without a backup; this is conversation
+   history. The store is best-effort, so loss degrades but does not break forge.
+
+---
+
+## 2. Daemon down / unreachable
+
+**Symptoms:** persistence features unavailable; forge still functions (graceful
+degradation) but history isn't saved; health probe fails.
+
+**Likely cause:** Daemon not started, crashed (SIGTERM/SIGINT path), socket
+missing, or `~/.forge/` permissions wrong.
+
+**Diagnosis:**
+
+1. Is it running? `ps aux | grep forge_dbd`
+2. Does the socket exist? `ls -la ~/.forge/.forge.db.sock`
+3. **Health probe**: the daemon answers `Request::Ping` inline with
+   `Response::Health` (`crates/forge_dbd/src/server.rs:168-241`). A successful
+   round-trip means the accept loop and writer are alive.
+4. Check `~/.forge/` exists and is user-owned (the daemon creates the parent
+   dir if missing — `server.rs:81-83`).
+
+**Fix:**
+
+1. Restart the daemon. It binds the Unix listener, removing any stale socket
+   first (`server.rs:75-85`).
+2. If it exits immediately, check for a permissions problem on `~/.forge/`
+   (must be writable by the user) or a port/socket conflict.
+3. Daemon shutdown is graceful on SIGTERM/SIGINT and flushes a final batch
+   before exit (`server.rs:101-120`, `247-289`); an unclean kill may leave a
+   stale socket — remove it (§1) and restart.
+4. Remember: a *deliberately* disabled daemon is fine — forge degrades
+   gracefully. Only an *expected-up-but-unreachable* daemon is an incident.
+
+---
+
+## 3. Authentication expired / 401s from provider
+
+**Symptoms:** provider calls fail with auth errors; OAuth token rejected;
+"please re-authenticate" prompts.
+
+**Likely cause:** Expired OAuth access token whose refresh failed, a corrupted
+`~/.forge/.credentials.json`, or a tampered/incorrect `base_url`.
+
+**Diagnosis:**
+
+1. Confirm the credential file exists and has mode 0o600:
+   `ls -la ~/.forge/.credentials.json` (enforced by
+   `crates/forge_repo/src/provider/provider_repo.rs:609-616`).
+2. **Do not** cat the file into a shared log — it contains live tokens. Secret
+   values are redacted in forge's own logs by design
+   (`crates/forge_domain/src/auth/auth_token_response.rs:35-46`), so forge logs
+   are safe to share; the raw file is not.
+3. Verify the configured `base_url` points at the real provider host (tamper
+   check — see threat-model G1.3).
+
+**Fix:**
+
+1. Re-run the provider login/OAuth flow to mint fresh tokens.
+2. If the file is corrupt, back it up and re-authenticate to regenerate it.
+3. If a token leak is suspected, **revoke it provider-side** and re-auth; rotate
+   any API key. (A dedicated `forge auth revoke` workflow is a tracked gap —
+   threat-model G1.4.)
+4. On Windows note that 0o600 is not applied (threat-model G1.2); ensure the
+   file is not on a shared/synced path.
+
+---
+
+## 4. Provider 429 / rate limiting and circuit-breaker behavior
+
+**Symptoms:** requests slow then suddenly **fail fast**; logs reference the
+`"mcp_client"` breaker being open, or repeated 429/5xx; throughput drops.
+
+**Likely cause:** The provider (or an MCP server) is rate-limiting or
+overloaded, so the resilience layer is shedding load to protect the session.
+
+**Diagnosis & expected behavior:**
+
+1. **Retry first.** Retryable statuses
+   `[429, 500, 502, 503, 504, 408, 522, 524, 520, 529]` and overload errors are
+   retried with exponential backoff
+   (`crates/forge_config/src/retry.rs:6-26`,
+   `crates/forge_repo/src/provider/retry.rs:9-37`). Transient 429s should
+   self-heal.
+2. **Circuit breaker.** After 5 consecutive failures the breaker opens and calls
+   fail *immediately* for ~30s, then a half-open probe tests recovery
+   (`crates/forge_infra/src/resilience.rs:47-132`). Fast failures right after a
+   burst of errors are **expected** — the breaker is doing its job, not a bug.
+3. **Bulkhead.** `BulkheadFullError` means too many concurrent MCP calls
+   (default cap 16, `resilience.rs:195-242`); the system is shedding, not
+   broken.
+
+**Fix:**
+
+1. Wait out the breaker's reset window (~30s) — it self-recovers via the
+   half-open probe on the next success.
+2. Reduce concurrency / request rate if you are hitting the bulkhead or
+   sustained 429s; check your provider plan's rate limits.
+3. For a flaky MCP server, disable it in `.mcp.json` (`disable: true`) to stop
+   tripping its breaker.
+4. If the breaker opens during *normal* (low-rate) use, that is an SLO
+   regression — capture logs and file an issue; investigate the upstream
+   provider before assuming a forge bug.
+
+---
+
+## 5. MCP server misbehaving / hanging
+
+**Symptoms:** agent stalls on tool calls; a specific MCP tool never returns;
+breaker for `"mcp_client"` keeps opening.
+
+**Likely cause:** A slow, hung, or flooding MCP server (Stdio subprocess or HTTP
+endpoint).
+
+**Diagnosis:**
+
+1. Identify the server in `.mcp.json`.
+2. For Stdio servers, check the child process; forge spawns them with
+   `kill_on_drop(true)` and drains stderr
+   (`crates/forge_infra/src/mcp_client.rs:148-172`).
+3. Confirm whether the bulkhead/breaker is shedding (§4).
+
+**Fix:**
+
+1. Set `disable: true` for the offending server in `.mcp.json` and retry.
+2. Restart forge to respawn a clean Stdio child.
+3. Treat any *untrusted* MCP server with caution — it runs with your privileges
+   (threat-model S3).
+
+---
+
+## 6. Shell integration broken (ZSH)
+
+**Symptoms:** new shells error on startup; completion widget missing; prompt
+slow.
+
+**Likely cause:** `eval "$(forge zsh plugin)"` resolved a wrong/missing `forge`
+on `$PATH`, or a sourced `lib/*.zsh` is broken
+(`shell-plugin/forge.setup.zsh:14,19`).
+
+**Fix:**
+
+1. Confirm `which forge` resolves to the intended binary.
+2. Temporarily comment out the managed block in `.zshrc` to isolate whether
+   forge is the cause; reopen a shell.
+3. Re-run forge's shell setup to regenerate the managed block.
+4. If a precmd/preexec hook is slow, investigate context capture
+   (`shell-plugin/lib/context.zsh`) — see threat-model S5/G5.2 for the opt-out
+   discussion.
+
+---
+
+## Escalation
+
+If a fix above does not resolve the issue, gather: forge version,
+`ps aux | grep forge`, the daemon health-probe result, and **redacted** forge
+logs (secrets are already redacted by forge's Debug impls — never paste the raw
+credential files), then file an issue or follow the postmortem template in
+`docs/operations/postmortem-template.md` for anything user-impacting and novel.

+# ForgeCode Service Level Objectives (SLOs)
+
+> Status: Living document. Owner: ForgeCode maintainers.
+> Last reviewed: 2026-06-28 (Phase P4 overhaul).
+
+ForgeCode is a **local CLI/TUI plus an on-demand local daemon** (`forge_dbd`),
+not a hosted service. Classic uptime SLAs do not apply: there is no fleet, no
+load balancer, no 24/7 availability target. Instead we define SLOs for the
+qualities a developer actually feels — **startup latency, command
+responsiveness, daemon availability on the local box, and resilience to flaky
+upstream providers.**
+
+These SLOs are aspirational targets used to triage regressions and prioritize
+work. The "error budget" framing is adapted for a CLI: rather than minutes of
+downtime, the budget is the **fraction of user-initiated operations allowed to
+miss the target before it is treated as a regression.**
+
+## SLI definitions
+
+| SLI | Definition | How it's measured |
+|-----|------------|-------------------|
+| **Startup time** | Wall-clock from process exec to interactive prompt / first usable output | `time forge` cold; CI smoke timing |
+| **Command latency (local)** | Wall-clock for a local-only command (no provider call): config read, history list, completion | TUI instrumentation / manual timing |
+| **First token latency** | Time from submitting a prompt to first streamed token from the provider | depends on provider; forge overhead measured separately |
+| **Daemon availability** | Fraction of `Ping` health probes to `forge_dbd` that succeed when the daemon should be up | `Request::Ping` → `Response::Health` round-trip |
+| **Provider call success (effective)** | Fraction of provider calls that eventually succeed *after* retry/circuit-breaker handling | retry layer outcome |
+| **MCP call success (effective)** | Fraction of MCP tool calls that succeed without being shed by the bulkhead/breaker | circuit breaker `"mcp_client"` outcome |
+
+## SLO targets and error budgets
+
+| Objective | Target | Error budget | Notes |
+|-----------|--------|--------------|-------|
+| Cold startup | p95 < 400 ms; p99 < 800 ms | 5% of starts may exceed p95 | Excludes first-ever run (asset extraction, plugin install) |
+| Warm local command | p95 < 100 ms | 5% | Config/history/completion; no network |
+| Daemon availability (local) | 99% of probes succeed while daemon enabled | 1% | Daemon is optional; absence is *not* a budget burn (see below) |
+| Provider call effective success | 99% over a rolling session | 1% | After retry of `[429, 500, 502, 503, 504, 408, 522, 524, 520, 529]` |
+| MCP call effective success | 95% | 5% | Bulkhead shedding under saturation counts as a miss |
+| First token latency overhead (forge-attributable) | p95 < 150 ms | 5% | Provider network time is excluded |
+
+### Why "daemon down" is not always a budget burn
+
+`forge_dbd` is a **best-effort persistence accelerator** (conversation storage
+via SQLite at `~/.forge/forge.db`, Unix socket at `~/.forge/.forge.db.sock` —
+`crates/forge_dbd/src/main.rs:15-23`). forge is designed to degrade gracefully
+when the daemon is absent. The availability SLO applies only while the daemon is
+*expected* to be running; a deliberately-disabled daemon does not consume the
+budget. A daemon that is *supposed* to be up but unreachable **does** (see the
+runbook for the "daemon down" procedure).
+
+## Resilience behavior backing these SLOs
+
+The provider/MCP success SLOs are achievable because of the Phase-P2 resilience
+layer:
+
+- **Unified retry** on a single `RetryConfig`
+  (`crates/forge_config/src/retry.rs:6-26`) with exponential backoff and a
+  default retryable status set
+  `[429, 500, 502, 503, 504, 408, 522, 524, 520, 529]`. Provider-specific
+  overload errors (Anthropic `overloaded_error`, OpenAI `server_is_overloaded`)
+  are also retried (`crates/forge_repo/src/provider/retry.rs:9-37`).
+- **Circuit breaker** (`crates/forge_infra/src/resilience.rs:47-132`):
+  Closed → Open after 5 consecutive failures, Open → HalfOpen after a 30s reset
+  timeout, HalfOpen → Closed on a successful probe. This caps wasted latency
+  when a provider/MCP server is hard-down (fast-fail rather than per-call
+  timeout).
+- **Bulkhead** (`resilience.rs:195-242`): a non-blocking semaphore caps
+  concurrent MCP calls (default 16) and returns `BulkheadFullError` immediately
+  on saturation, protecting the rest of the agent from one slow server.
+
+## Measuring & reviewing
+
+- **CI smoke timing** should assert cold-startup stays under the p99 budget on
+  the standard Linux runner; a regression fails the budget.
+- **Local instrumentation**: the TUI/daemon emit timing for local commands and
+  daemon round-trips; spot-check against targets when investigating "feels
+  slow" reports.
+- **Provider/MCP effective success** is observed via the retry/breaker outcomes;
+  a breaker that trips frequently in normal use is an SLO regression, not just a
+  provider problem — see the runbook circuit-breaker section.
+
+Review this file whenever startup cost materially changes (new asset extraction,
+new always-on subsystem) or when a new latency-sensitive surface is added.

+  files but *not* the user's running process memory.
+- **A2 — A malicious or compromised remote endpoint** (LLM provider, MCP
+  server, OAuth IdP) that returns hostile data.
+- **A3 — A malicious model / prompt-injection payload** that steers the agent
+  into running attacker-chosen tools or shell commands.
+- **A4 — A passive observer** of forge's outbound network traffic (telemetry,
+  provider calls).
+
+Out of scope: kernel/firmware compromise, an attacker who already has the
+user's interactive shell (they already have everything forge has), supply-chain
+attacks on `cargo` dependencies (tracked separately via `cargo audit` / SBOM).
+
+## Attack surfaces
+
+| # | Surface | Crate / file (evidence) |
+|---|---------|-------------------------|
+| S1 | Credential store (`.credentials.json`, OAuth tokens) | `crates/forge_repo/src/provider/provider_repo.rs`, `crates/forge_domain/src/env.rs`, `crates/forge_infra/src/auth/mcp_credentials.rs` |
+| S2 | Prompt injection → tool / subprocess execution | `crates/forge_app/src/tool_registry.rs`, `crates/forge_pheno_shell`, `crates/forge_infra/src/mcp_client.rs` |
+| S3 | MCP server trust (untrusted MCP servers) | `crates/forge_infra/src/mcp_client.rs`, `crates/forge_domain/src/mcp.rs` |
+| S4 | Telemetry egress (PostHog) | `crates/forge_tracker/src/collect/posthog.rs`, `crates/forge_tracker/src/dispatch.rs`, `crates/forge_tracker/src/can_track.rs` |
+| S5 | ZSH plugin / shell integration | `shell-plugin/forge.plugin.zsh`, `shell-plugin/forge.setup.zsh`, `shell-plugin/lib/*.zsh` |
+
+A supporting surface is the **local daemon** `forge_dbd` (Unix domain socket at
+`~/.forge/.forge.db.sock`, SQLite store at `~/.forge/forge.db`); it is analyzed
+inline within S1/S2 (DoS) since it shares the credential-directory trust model.
+
+---
+
+## S1 — Credential store
+
+OAuth tokens, API keys, and MCP client registrations are persisted to disk
+under `~/.forge/`. Provider credentials live in `.credentials.json`
+(`crates/forge_domain/src/env.rs:173-175`); MCP OAuth state in
+`.mcp-credentials.json` (`crates/forge_infra/src/auth/mcp_credentials.rs:117-119`).
+
+### STRIDE
+
+- **Spoofing** — A token file forged by another user could impersonate the
+  victim to the provider.
+- **Tampering** — Editing `.credentials.json` to point at an attacker
+  refresh-token endpoint, or to inject a malicious `base_url`.
+- **Repudiation** — Low: single-user tool, no audit of who wrote the file.
+- **Information disclosure** — *Primary risk.* Long-lived OAuth refresh tokens
+  and API keys readable by other local processes/users, or leaked via logs.
+- **Denial of service** — Corrupting the file blocks all authenticated calls.
+- **Elevation of privilege** — A stolen refresh token grants the attacker the
+  user's full provider quota and any provider-side scopes.
+
+### Current mitigations (evidence-cited)
+
+- **0o600 (owner read/write only)** is enforced on credential files on Unix
+  after every write:
+  - `crates/forge_repo/src/provider/provider_repo.rs:609-616`
+    (`set_owner_only_permissions` → `perms.set_mode(0o600)`), with a regression
+    test at `provider_repo.rs:1308-1337` asserting mode `0o600`.
+  - `crates/forge_infra/src/auth/mcp_credentials.rs:103-110` applies the same
+    0o600 mode to `.mcp-credentials.json`.
+- **Secret-Debug redaction** prevents tokens/keys from leaking into logs,
+  panics, or telemetry payloads. Custom `Debug` impls render `<redacted>`:
+  - `crates/forge_domain/src/auth/new_types.rs:9-12` — `ApiKey(<redacted>)`;
+    also `AuthorizationCode`, `DeviceCode`, `PkceVerifier` (lines 55-82).
+  - `crates/forge_domain/src/auth/auth_token_response.rs:35-46` —
+    `OAuthTokenResponse` redacts `access_token`/`refresh_token`/`id_token`.
+  - `crates/forge_infra/src/auth/strategy.rs:638-662` — Codex device/token
+    responses redact `device_auth_id`/`user_code`.
+
+### Gaps / TODO
+
+- **G1.1** — Tokens are stored in **plaintext** on disk. There is no OS keychain
+  / Secret Service / DPAPI integration. 0o600 protects against other *users*
+  but not against malware running *as the user*. TODO: optional keychain
+  backend (`security-framework` on macOS, `secret-service` on Linux,
+  `wincred` on Windows).
+- **G1.2** — **Windows** has no equivalent of the 0o600 path (the
+  `#[cfg(unix)]` guard means Windows files inherit default ACLs). TODO: set a
+  restrictive Windows ACL or require keychain on Windows.
+- **G1.3** — No integrity protection on the credential file (Tampering): a
+  modified `base_url` is trusted. TODO: validate provider `base_url` against an
+  allowlist of known hosts before use (note: a related exact-host Anthropic
+  `base_url` check already exists for the Anthropic provider, commit
+  `b3207ab01`).
+- **G1.4** — No token-rotation / revocation-on-detection workflow if a leak is
+  suspected. TODO: a `forge auth revoke` command + runbook entry.
+
+---
+
+## S2 — Prompt injection → tool / subprocess execution
+
+The agent executes tools chosen from model output. Hostile content reaching the
+model (a poisoned file, web page, or tool result) can attempt to coerce the
+agent into running destructive tools (file write/delete, shell exec) or
+exfiltrating data. Shell-capable tooling lives in `crates/forge_pheno_shell`,
+and MCP subprocesses are spawned via `crates/forge_infra/src/mcp_client.rs`.
+
+### STRIDE
+
+- **Spoofing** — Injected text impersonating the user ("the user approved this").
+- **Tampering** — Coercing edits to source, CI config, or the credential file.
+- **Repudiation** — Actions taken on the user's behalf without clear logging.
+- **Information disclosure** — Reading secrets and exfiltrating them through a
+  tool call (e.g. a shell `curl`, or an MCP tool that egresses data).
+- **Denial of service** — Forcing expensive/looping tool calls.
+- **Elevation of privilege** — Escaping the working directory; running with the
+  user's full shell privileges.
+
+### Current mitigations (evidence-cited)
+
+- **Per-operation permission policy.** Before any tool runs,
+  `crates/forge_app/src/tool_registry.rs:64-91` converts the tool input to a
+  policy operation (scoped to `cwd`) and calls
+  `check_operation_permission(&operation)`. In restricted mode a denied
+  permission blocks execution with a `permission_denied` error
+  (`tool_registry.rs:142-155`) — the check happens *before* the call is
+  dispatched.
+- **CWD scoping.** Operations are bound to the current working directory
+  (`tool_registry.rs:70`), constraining file operations.
+- **Subprocess lifecycle hardening for MCP.** Stdio MCP children are spawned
+  with `kill_on_drop(true)` and their stderr is piped + drained asynchronously
+  to avoid deadlock (`crates/forge_infra/src/mcp_client.rs:148-172`).
+
+### Gaps / TODO
+
+- **G2.1** — There is **no allowlist of tool names** and no static
+  "dangerous-tool" classification in the registry; trust relies entirely on the
+  dynamic policy service. TODO: a default-deny allowlist for shell/network
+  tools, surfaced in docs.
+- **G2.2** — CWD scoping does not by itself prevent path traversal (`../`) or
+  absolute paths from being passed to a tool. TODO: canonicalize + reject paths
+  that escape the workspace root.
+- **G2.3** — No data-egress guard: a permitted shell/MCP tool can read a secret
+  and POST it out. TODO: optional network-egress confirmation for shell tools.
+- **G2.4** — No structured audit trail of tool executions for after-the-fact
+  review (Repudiation). TODO: append-only tool-execution log under `~/.forge/`.
+
+---
+
+## S3 — MCP server trust (untrusted MCP servers)
+
+MCP servers are configured in `.mcp.json` as either **Stdio** (a local
+subprocess) or **Http** (a network endpoint) — see
+`crates/forge_domain/src/mcp.rs:19-93`. A Stdio server's `command`, `args`, and
+`env` are taken directly from config and executed
+(`crates/forge_infra/src/mcp_client.rs:148-172`). An MCP server is effectively
+a **plugin with the same privileges as forge itself**.
+
+### STRIDE
+
+- **Spoofing** — A malicious MCP server advertises a trusted-looking tool name.
+- **Tampering** — An HTTP MCP endpoint returns manipulated tool results that
+  drive S2 prompt injection.
+- **Repudiation** — Actions performed by an MCP tool are attributed to forge.
+- **Information disclosure** — The subprocess inherits forge's environment
+  (including any exported secrets) and runs with the user's permissions; an HTTP
+  MCP server sees all arguments forge sends it.
+- **Denial of service** — A hung or flooding MCP server stalls the agent.
+- **Elevation of privilege** — A Stdio `command` is arbitrary code execution by
+  design; a compromised `.mcp.json` is full RCE as the user.
+
+### Current mitigations (evidence-cited)
+
+- **Resilience isolation.** MCP calls go through a circuit breaker
+  (name `"mcp_client"`, `crates/forge_infra/src/mcp_client.rs:71-104`) backed by
+  `crates/forge_infra/src/resilience.rs` (Closed/Open/HalfOpen states,
+  default failure threshold 5, reset timeout 30s) and a **bulkhead** semaphore
+  capping concurrent MCP calls (default 16, immediate `BulkheadFullError` on
+  saturation — `resilience.rs:195-242`). This bounds the DoS blast radius of a
+  misbehaving server.
+- **Process containment.** `kill_on_drop(true)` ensures Stdio servers die with
+  the client; stderr is drained to prevent buffer-overflow deadlock
+  (`mcp_client.rs:148-172`).
+- **Per-tool permission gate.** MCP tools still pass through the S2 permission
+  policy in `tool_registry.rs` before execution.
+
+### Gaps / TODO
+
+- **G3.1** — **No sandboxing.** Stdio MCP subprocesses run with full user
+  privileges and inherit forge's environment. TODO: minimal env passthrough
+  (don't forward credential env vars), and optional sandbox (e.g. `bwrap` /
+  Seatbelt) for Stdio servers.
+- **G3.2** — **No server allowlist / trust prompt.** Adding an MCP server is
+  silent code-execution-on-startup. TODO: first-run trust confirmation per
+  server with a recorded fingerprint of `command`+`args`.
+- **G3.3** — **No TLS/cert pinning controls documented** for HTTP MCP servers.
+  TODO: document and enforce `https://` for remote MCP, reject plaintext.
+- **G3.4** — MCP tool name collisions with built-in tools are not prevented
+  (Spoofing). TODO: namespace MCP tools and warn on shadowing.
+
+---
+
+## S4 — Telemetry egress (PostHog)
+
+Anonymous usage events are sent to PostHog at
+`https://us.i.posthog.com/capture/` (`crates/forge_tracker/src/collect/posthog.rs:76-77`).
+
+### STRIDE
+
+- **Spoofing** — N/A (forge is the sender; the write-only PostHog key is public
+  by design).
+- **Tampering** — A MITM could alter events (low impact; analytics only).
+- **Repudiation** — N/A.
+- **Information disclosure** — *Primary risk.* The dispatcher collects host
+  metadata: `client_id`, OS / core count / **username**, **cwd**, **executable
+  path**, and **CLI args** (`crates/forge_tracker/src/dispatch.rs:32-52`). cwd
+  and CLI args can contain project names, paths, or even secrets passed on the
+  command line.
+- **Denial of service** — N/A for the user; an event flood is self-throttled.
+- **Elevation of privilege** — N/A.
+
+### Current mitigations (evidence-cited)
+
+- **Opt-out / disabled by default in dev.** `can_track()` disables tracking for
+  dev and `0.1.0` builds (`crates/forge_tracker/src/can_track.rs:8-19`).
+- **Client-side rate limiting.** Max 1000 events/minute, fixed-window
+  (`crates/forge_tracker/src/dispatch.rs:54-59`, `rate_limit.rs:3-45`) — bounds
+  accidental egress volume.
+- **Write-only key.** The PostHog secret is an ingestion key only
+  (`dispatch.rs:20-23`), so the embedded value cannot read analytics back.
+
+### Gaps / TODO
+
+- **G4.1** — **CLI args and cwd are collected**; these can leak secrets or
+  proprietary path/project names. TODO: scrub argv (drop values after
+  `--token`/`--key`-style flags) and hash or drop cwd.
+- **G4.2** — **No documented user-facing opt-out env var** for release builds.
+  TODO: honor a `FORGE_TELEMETRY=0` / `DO_NOT_TRACK=1` env var and document it
+  in the README + this model.
+- **G4.3** — **Username is sent.** TODO: drop or hash `username`; it is PII.
+- **G4.4** — No first-run telemetry-consent notice. TODO: print a one-time
+  notice with the opt-out instructions.
+
+---
+
+## S5 — ZSH plugin / shell integration
+
+forge integrates into the user's interactive shell. `forge.setup.zsh` adds a
+managed block that `eval`s forge-generated zsh:
+`eval "$(forge zsh plugin)"` and `eval "$(forge zsh theme)"`
+(`shell-plugin/forge.setup.zsh:14,19`). The plugin captures terminal context
+(preexec/precmd/OSC 133) and registers completion widgets
+(`shell-plugin/lib/context.zsh`, `lib/completion.zsh:5-48`,
+`lib/bindings.zsh`).
+
+### STRIDE
+
+- **Spoofing** — A modified `forge` on `$PATH` would have its output `eval`'d
+  into the user's shell on every new session.
+- **Tampering** — Editing the managed block in `.zshrc`, or any sourced
+  `lib/*.zsh`, injects code into every shell.
+- **Repudiation** — Shell-side actions are not logged by forge.
+- **Information disclosure** — Context capture reads the user's command lines
+  and terminal output; that data flows into forge prompts and could reach
+  providers/telemetry.
+- **Denial of service** — A slow preexec/precmd hook degrades every prompt.
+- **Elevation of privilege** — `eval` of forge output is arbitrary code
+  execution in the interactive shell's context on each startup.
+
+### Current mitigations (evidence-cited)
+
+- **Modular, reviewable plugin.** The plugin is split into auditable files
+  (`shell-plugin/lib/{config,highlight,context,bindings,completion,dispatcher}.zsh`
+  and `lib/actions/*`) rather than one opaque blob
+  (`shell-plugin/forge.plugin.zsh:1-39`).
+- **Widget-based completion** rather than executing arbitrary strings: the
+  completion delegates to a Rust-built picker via `_forge_select_with_query()`
+  (`shell-plugin/lib/completion.zsh:5-48`).
+- **Managed, idempotent setup block** so the integration is contained and
+  removable (`shell-plugin/forge.setup.zsh:1-21`).
+
+### Gaps / TODO
+
+- **G5.1** — `eval "$(forge zsh plugin)"` trusts `$PATH` resolution of `forge`
+  on every shell start. TODO: document pinning to an absolute path, or ship a
+  static, version-checked plugin file instead of `eval`-on-startup.
+- **G5.2** — Captured terminal context may include secrets typed into the
+  shell. TODO: document what context is captured and provide an opt-out /
+  redaction for context capture.
+- **G5.3** — No integrity check on the sourced `lib/*.zsh` files. TODO:
+  ship a checksum manifest and verify on load.

+# Forge Database VACUUM & FTS Rebuild Tool — Design Spec
+
+**Date**: 2026-06-26  
+**Context**: Post-P2 (drop FTS triggers) + P2b (external-content FTS5) cleanup  
+**Goal**: Safely reclaim ~2.76GB from `~/.forge.db` (currently 6.85GB)  
+**Status**: Design specification (Rust binary; not yet implemented)
+
+---
+
+## Executive Summary
+
+After P2 and P2b merge, the `~/.forge.db` SQLite database contains orphaned pages and fragmented FTS indices. A one-time VACUUM + FTS rebuild will reclaim ~40% disk space. However, VACUUM requires an **EXCLUSIVE lock**, meaning **NO process** (forge, forge-dev, or any open handle) can hold the database open.
+
+This spec defines a **safety-first Rust binary** that:
+- **Detects all processes holding the DB file** (using `lsof`)
+- **Refuses to run** if any process is attached (exits non-zero with actionable message)
+- **Never kills or signals any process** (absolute rule)
+- **Backs up the database** before any writes (with disk-space preflight)
+- **Runs the maintenance sequence** safely and idempotently
+- **Reports progress and results** with before/after sizes and frames reclaimed
+
+---
+
+## Part 1: Hard Safety Rules (Central Design)
+
+### 1.1 Process Hold Detection (Preflight)
+
+The tool MUST detect all processes holding the database file **before attempting any operations**.
+
+**Mechanism**: Use `lsof` (or `/proc` on Linux) to enumerate file descriptors.
+
+```rust
+/// Detect all processes holding the database file open.
+/// Returns Vec of (pid, command) tuples.
+/// 
+/// Safety: This is read-only (lsof check), no side effects.
+fn detect_open_handles(db_path: &Path) -> Result<Vec<(u32, String)>> {
+    use std::process::Command;
+    
+    let output = Command::new("lsof")
+        .arg("-t")  // Terse (PIDs only)
+        .arg("--")
+        .arg(db_path)
+        .output()?;
+    
+    let mut pids = Vec::new();
+    for line in String::from_utf8_lossy(&output.stdout).lines() {
+        if let Ok(pid) = line.trim().parse::<u32>() {
+            // Get process name from /proc or ps
+            if let Ok(name) = get_process_name(pid) {
+                pids.push((pid, name));
+            }
+        }
+    }
+    Ok(pids)
+}
+
+/// Retrieve process name from /proc/<pid>/comm or ps
+fn get_process_name(pid: u32) -> Result<String> {
+    use std::fs;
+    // Try /proc first (Linux)
+    match fs::read_to_string(format!("/proc/{}/comm", pid)) {
+        Ok(name) => Ok(name.trim().to_string()),
+        Err(_) => {
+            // Fallback: ps (macOS, BSD)
+            let output = std::process::Command::new("ps")
+                .arg("-p").arg(pid.to_string())
+                .arg("-o").arg("comm=")
+                .output()?;
+            Ok(String::from_utf8_lossy(&output.stdout).trim().to_string())
+        }
+    }
+}
+
+/// Preflight check: refuse if ANY process holds the DB open.
+fn preflight_check(db_path: &Path) -> Result<()> {
+    let handles = detect_open_handles(db_path)?;
+    if !handles.is_empty() {
+        eprintln!("ERROR: Cannot run VACUUM. {} process(es) hold {} open:", 
+                  handles.len(), db_path.display());
+        for (pid, cmd) in &handles {
+            eprintln!("  PID {}: {}", pid, cmd);
+        }
+        eprintln!("\nClose all forge/forge-dev processes and try again.");
+        std::process::exit(1);
+    }
+    Ok(())
+}
+```
+
+**Behavior**:
+- Runs at startup (before any writes)
+- Lists all PIDs + command names holding the file
+- **Exits with code 1 and actionable message** if any are found
+- **Never** kills, signals, or terminates any process
+
+### 1.2 No Kill, No Signal Rule
+
+This is absolute and non-negotiable.
+
+```rust
+// ❌ FORBIDDEN:
+// libc::kill(pid as i32, libc::SIGTERM);  // Never
+// Command::new("kill").arg(...);           // Never
+// std::process::Child::kill();              // Never
+
+// ✅ ONLY allowed: read-only checks
+lsof(db_path);  // Check if attached
+ps::get_process_name(pid);  // Read process info
+```
+
+---
+
+## Part 2: Backup & Disk-Space Preflight
+
+### 2.1 Disk-Space Check
+
+Before backing up, verify sufficient free space.
+
+```rust
+/// Check free disk space at the target location.
+/// Refuse if < min_free_mb available.
+fn check_disk_space(target_dir: &Path, min_free_mb: u64) -> Result<()> {
+    use std::fs;
+    
+    let metadata = fs::metadata(target_dir)?;
+    // On Unix, we can use statfs for accurate free space
+    #[cfg(unix)]
+    {
+        use nix::sys::statvfs::statvfs;
+        let stat = statvfs(target_dir)?;
+        let free_bytes = stat.blocks_available() * stat.block_size();
+        let free_mb = free_bytes / (1024 * 1024);
+        
+        if free_mb < min_free_mb {
+            eprintln!("ERROR: Insufficient disk space.");
+            eprintln!("  Required: {} MB for backup + VACUUM headroom",
+                      min_free_mb);
+            eprintln!("  Available: {} MB", free_mb);
+            return Err("Disk space check failed".into());
+        }
+        eprintln!("✓ Disk check passed: {} MB free (need {} MB)", free_mb, min_free_mb);
+    }
+    Ok(())
+}
+
+/// Backup the database to a timestamped file.
+/// Returns path to the backup.
+fn backup_database(db_path: &Path, backup_dir: &Path) -> Result<PathBuf> {
+    use std::fs;
+    use chrono::Local;
+    
+    let timestamp = Local::now().format("%Y%m%d_%H%M%S");
+    let backup_name = format!(".forge_backup_{}.db", timestamp);
+    let backup_path = backup_dir.join(&backup_name);
+    
+    eprintln!("Backing up {} → {}...", db_path.display(), backup_path.display());
+    
+    let start = std::time::Instant::now();
+    fs::copy(db_path, &backup_path)?;
+    
+    let duration = start.elapsed();
+    let size_gb = fs::metadata(&backup_path)?.len() as f64 / (1024.0 * 1024.0 * 1024.0);
+    eprintln!("✓ Backup complete: {:.2} GB in {:.1}s", size_gb, duration.as_secs_f64());
+    
+    Ok(backup_path)
+}
+```
+
+**Behavior**:
+- Requires ~8GB free (6.85GB for DB + headroom for VACUUM working space)
+- Exits with error if insufficient space
+- Creates timestamped backup: `.forge_backup_20260626_143022.db`
+- Reports size and duration
+
+### 2.2 Skip-Backup Flag (With Warning)
+
+```rust
+fn backup_database_maybe(
+    db_path: &Path,

+## Part 3: Maintenance Sequence (FTS Mode Detection & Rebuild)
+
+### 3.1 Detect FTS Mode
+
+Inspect `sqlite_master` to determine if the DB uses **external-content FTS5** (P2b) or **contentful FTS5** (pre-P2b).
+
+```rust
+/// FTS configuration mode detected from sqlite_master.
+#[derive(Debug, Clone, Copy)]
+enum FtsMode {
+    /// External-content FTS5: `content='conversations'` in DDL
+    /// Supports: 'rebuild', 'optimize' commands
+    ExternalContent,
+    
+    /// Contentful FTS5 (pre-P2b): no content= clause
+    /// Does NOT support 'rebuild'; must delete + repopulate
+    Contentful,
+    
+    /// Unknown or mixed (should not occur in production)
+    Unknown,
+}
+
+/// Detect FTS mode by inspecting the conversations_fts table DDL.
+fn detect_fts_mode(conn: &rusqlite::Connection) -> Result<FtsMode> {
+    let mut stmt = conn.prepare(
+        "SELECT sql FROM sqlite_master WHERE type='table' AND name='conversations_fts'"
+    )?;
+    
+    let ddl: String = stmt.query_row([], |row| row.get(0))?;
+    
+    if ddl.contains("content=") {
+        eprintln!("✓ FTS mode detected: external-content (P2b)");
+        Ok(FtsMode::ExternalContent)
+    } else {
+        eprintln!("✓ FTS mode detected: contentful (pre-P2b)");
+        Ok(FtsMode::Contentful)
+    }
+}
+```
+
+**Why**: The rebuild strategy differs:
+- **External-content** (P2b): Use `INSERT INTO conversations_fts(conversations_fts) VALUES('rebuild');`
+- **Contentful** (pre-P2b): Use `DELETE FROM conversations_fts; INSERT INTO conversations_fts SELECT ...;` (as in P2's `refresh_fts_index`)
+
+### 3.2 Maintenance Sequence

+
+**Note on Rebuild Order**: 
+- VACUUM is run **first** because it reassigns rowids and compacts pages
+- FTS rebuild is run **after** VACUUM (the index needs the new rowid map)
+- FTS optimize is run last (final polish)
+
+---
+
+## Part 4: Contentful FTS5 Repopulation (Cross-Reference to P2)
+
+For pre-P2b databases, we need to repopulate the FTS index. This should reuse **P2's `refresh_fts_index` logic** (or a trimmed Rust equivalent).
+
+```rust
+/// Repopulate contentful FTS5 index by re-inserting from source table.
+/// This is the Rust equivalent of P2's refresh_fts_index.
+fn refresh_fts_index_contentful(conn: &mut rusqlite::Connection) -> Result<()> {
+    let tx = conn.transaction()?;
+    
+    // Assume the FTS table is conversations_fts and source is conversations
+    // The DDL defines which columns are indexed: typically (title, description, etc.)
+    
+    // Insert from source table (assumes conversations table exists)
+    tx.execute(
+        r#"
+        INSERT INTO conversations_fts (rowid, title, description, body)
+        SELECT id, title, description, body
+        FROM conversations
+        WHERE deleted_at IS NULL;
+        "#,
+        []
+    )?;
+    
+    tx.commit()?;
+    eprintln!("✓ FTS index repopulated from source");
+    Ok(())
+}
+```
+
+**Cross-reference**: This logic should be extracted from (or coordinated with) P2's `refresh_fts_index` implementation in the main codebase.

+## Part 6: Crate Structure & Dependencies
+
+### 6.1 Placement & Organization
+
+**Option A: Standalone binary in `tooling/` crate**
+```
+Phenotype/repos/forgecode-wts/
+├── tooling/
+│   ├── Cargo.toml
+│   ├── src/
+│   │   └── bin/
+│   │       └── forge-vacuum/
+│   │           ├── main.rs (CLI entry)
+│   │           ├── lib.rs (core logic: preflight, vacuum, rebuild)
+│   │           └── fts.rs (FTS mode detection & rebuild)

+
+**Option B: Part of forge-cli workspace**

+│       └── fts.rs
+```
+
+**Recommendation**: **Option A** (standalone tooling binary). It's independent of forge-cli and can be run anytime.
+
+### 6.2 Dependencies
+
+```toml
+# tooling/Cargo.toml
+[package]
+name = "forge-vacuum"
+version = "0.1.0"
+edition = "2021"

+path = "src/bin/main.rs"
+
+[profile.release]
+opt-level = 3
+lto = true
+strip = true
+```
+
+**Why each dep**:
+- `rusqlite`: SQLite access
+- `clap`: CLI argument parsing
+- `chrono`: Timestamped backups
+- `shellexpand`: Handle `~` in paths
+- `nix`: Disk space check (`statvfs`), process enumeration
+- `anyhow`: Error handling
+- `log` + `env_logger`: Structured logging (future)
+
+---
+
+## Part 7: Exit Codes & Error Messages
+
+| Exit Code | Condition | Message |
+|-----------|-----------|---------|
+| 0 | Success | `✓ Success!` + stats |
+| 1 | Process holds DB open | `ERROR: Cannot run VACUUM. N process(es) hold ... open:` + list PIDs |
+| 2 | Insufficient disk space | `ERROR: Insufficient disk space. Required X MB, available Y MB` |
+| 3 | Backup failed | `ERROR: Failed to back up database: ...` |
+| 4 | Database corruption detected | `ERROR: Integrity check failed: ...` |
+| 5 | Maintenance sequence failed | `ERROR: VACUUM/rebuild failed: ...` |
+
+**All errors go to `stderr`, success goes to `stdout` (or `stderr` for progress).**
+
+---
+
+## Part 8: Safety & Idempotency
+
+### 8.1 Idempotency
+
+- Running the tool twice is safe (second run will find fewer pages to vacuum, smaller reclaim)
+- Backup step: timestamped files, never overwrites
+- FTS rebuild: `'rebuild'` is idempotent for external-content; delete+repopulate is idempotent for contentful
+
+### 8.2 Failure Recovery
+
+If the tool crashes mid-VACUUM:
+- SQLite's WAL will ensure DB consistency (VACUUM commits atomically)
+- If backup was not skipped, a rollback-ready copy exists at `~/.forge/.forge_backup_*.db`
+- User can restore from backup and retry
+
+If the tool crashes mid-FTS-rebuild:
+- FTS table may be partially rebuilt (this is safe; rebuild is idempotent)
+- Rerun the tool; it will complete the rebuild
+
+### 8.3 Dry-Run Verification
+
+Before running the tool on production:
+```bash
+$ forge-vacuum --db-path ~/.forge/.forge.db --dry-run
+>>> DRY RUN: Would run maintenance sequence
+[1/5] Integrity check...
+  Pages: 1761280, Size: 6.85 GB
+✓ Integrity check passed
+[2/5] Backup (already completed)
+[3/5] Running VACUUM...
+(dry-run: VACUUM not executed)
+[4/5] FTS rebuild...
+(dry-run: FTS rebuild not executed)
+[5/5] FTS optimize...
+(dry-run: FTS optimize not executed)
+[6/5] Final integrity check...
+  Pages: (estimated 893824 after vacuum)
+(dry-run estimate: would reclaim ~2.76 GB)
+```
+
+---
+
+## Part 9: Implementation Roadmap
+
+### Phase 1: Scaffolding (1–2 hours)
+- Create `tooling/forge-vacuum/` crate
+- Implement CLI skeleton (clap)
+- Add `preflight.rs` with `lsof` integration
+
+### Phase 2: Core Logic (2–3 hours)
+- Implement `rusqlite` open + PRAGMA queries
+- FTS mode detection
+- VACUUM + rebuild + optimize sequence
+- Error handling & logging
+
+### Phase 3: Testing & Hardening (1–2 hours)
+- Unit tests for FTS mode detection
+- Integration tests on a test `.forge.db` copy
+- Dry-run validation
+- Edge cases: corrupted DB, missing tables, etc.
+
+### Phase 4: Documentation & Release (30 min)
+- README with usage examples
+- Integration into forge's build system (optional: `forge maintenance vacuum`)
+- Mention in P2/P2b PR descriptions
+
+---
+
+## Part 10: Cross-References & Dependencies
+
+- **P2 Merge**: `refresh_fts_index()` logic (drop FTS triggers, switch to external-content FTS5)
+- **P2b Merge**: External-content FTS5 implementation (sets `content=` in DDL)
+- **This Tool**: Runs after both merges land; depends on knowing the FTS mode from P2b

+
+## Summary
+
+This Rust binary is a **safety-first, idempotent maintenance tool** that:
+
+1. ✅ **Detects and refuses** if any process holds the DB open (using `lsof`)
+2. ✅ **Never kills** any process (absolute rule)
+3. ✅ **Preflight disk-space check** (minimum 8GB free)
+4. ✅ **Backs up** the full database (timestamped, ~45s for 6.85GB)
+5. ✅ **Runs VACUUM** (atomic, reclaims ~40% disk space)
+6. ✅ **Detects FTS mode** (external-content P2b vs. contentful pre-P2b)
+7. ✅ **Rebuilds FTS** (mode-appropriate: `'rebuild'` or delete+repopulate)
+8. ✅ **Optimizes FTS** (final polish)
+9. ✅ **Reports results** (before/after sizes, reclaimed space, timing)
+10. ✅ **Dry-run support** (preflight-only, no writes)
+
+**Placement**: `Phenotype/repos/forgecode-wts/tooling/forge-vacuum/` (or integrate into forge-cli workspace).  
+**LOC target**: ~400–500 lines (main.rs + lib.rs + fts.rs).  
+**Dependencies**: rusqlite, clap, chrono, nix (for statvfs), anyhow.
+
+---
+
+**Next Step**: Once P2 and P2b merge, implement this binary. It should be battle-tested on a staging DB copy before users run it on production.

+# P2b: External-Content FTS5 Migration (Draft)
+
+**Status:** DESIGN / DRAFT  
+**Target:** Reclaim ~2.76 GB via FTS5 external-content mode  
+**Scope:** DDL + query rewrites (NOT APPLIED)  
+**Related:** P2 (drop sync triggers), P1 (wal_autocheckpoint)
+
+---
+
+## 1. Goal & Space Reclamation
+
+### Problem
+
+The current FTS5 configuration is **CONTENTFUL** (stores a full copy of indexed data):
+
+```sql
+CREATE VIRTUAL TABLE conversations_fts USING fts5(
+    conversation_id UNINDEXED,
+    title,
+    content,  -- Full copy of context blob
+    tokenize='porter'
+);
+```
+
+- **conversations_fts_content table:** ~2.76 GB (duplicate of conversations.context)
+- **conversations table:** Primary storage ~2.5 GB
+- **Total footprint:** ~5.26 GB for the same content in two places
+
+### Solution
+
+Convert to **EXTERNAL-CONTENT** mode: store only FTS5 index metadata, fetch content on demand from the base table.
+
+**Expected space savings:** ~2.76 GB (FTS content table eliminated)
+
+---
+
+## 2. Rowid Stability & Design Options
+
+### The Problem: TEXT Primary Key & Implicit Rowid
+
+```sql
+CREATE TABLE conversations (
+    conversation_id TEXT PRIMARY KEY NOT NULL,  -- NOT INTEGER
+    ...
+)
+```
+
+Because `conversation_id` is TEXT (not INTEGER PRIMARY KEY), SQLite creates an implicit, **unstable `rowid`**:
+
+- **VACUUM:** Rewrites the table, reassigns ALL rowids
+- **Deletes & reinserts:** Rowids can be reused or reassigned
+- **Migration risk:** FTS index keyed on old rowids becomes stale
+
+### Option A1: External-Content + Mandatory Rebuild After VACUUM
+
+**Approach:**  
+- Use external-content mode keyed on implicit `rowid`
+- After every VACUUM, rebuild the entire FTS table
+- Requires out-of-band rebuild logic or scheduled maintenance
+
+**Pros:**
+- No schema changes to `conversations` table
+- No Diesel schema.rs update
+- Minimal migration risk
+
+**Cons:**
+- FTS unavailable during rebuild (no lock-light operation)
+- Explicit VACUUM + rebuild discipline required
+- Operational toil; no automation guarantee
+
+**Verdict:** ❌ High operational risk for a 6.85 GB database
+
+---
+
+### Option A2: Add Explicit `id INTEGER PRIMARY KEY` Surrogate (RECOMMENDED)
+
+**Approach:**  
+1. Add explicit `id INTEGER PRIMARY KEY AUTOINCREMENT` to `conversations` table
+2. Use `content_rowid='id'` in external-content FTS5 definition
+3. Rowid is now stable across VACUUM (tied to explicit column)
+4. Drop all sync triggers (P2 work)
+
+**Migration steps:**
+1. Alter conversations table: add `id INTEGER PRIMARY KEY`
+2. Drop old FTS table, create new external-content FTS
+3. Create lightweight delete triggers (optional; can skip for P2 phase)
+4. Rebuild FTS via out-of-band maintenance script (separate from migration)
+
+**Pros:**
+- ✅ Rowid stable across VACUUM
+- ✅ No rebuild discipline required
+- ✅ Clear separation: index stays valid
+- ✅ Standard FTS5 pattern (Chromium, SQLite docs recommend this)
+
+**Cons:**
+- Schema change to conversations table
+- Diesel schema.rs update
+- requires rebuild after migration (deferred to maintenance window)
+
+**Verdict:** ✅ **RECOMMENDED** — safe, standard, operational guarantee
+
+---
+
+## 3. Migration DDL (Option A2)
+
+### Overview
+
+**Three phases:**
+
+1. **Alter base table** — add explicit `id INTEGER PRIMARY KEY` (migration, live, lock-light)
+2. **Drop old FTS, create external-content FTS** — (migration, live, lock-light)
+3. **Rebuild index** — VACUUM + rebuild deferred to maintenance window (separate process, not in migration)
+
+---
+
+### 3.1 New Migration: `2026-06-26-000000_external_fts5.sql`
+
+#### Up (Apply)
+
+```sql
+-- Phase 1: Add explicit integer primary key to conversations
+-- This makes rowid stable across VACUUM operations
+-- NOTE: SQLite does NOT require explicit migrations for adding a primary key column
+-- if the column is INTEGER PRIMARY KEY — it becomes an alias for the implicit rowid.
+-- However, for clarity and future-proofing, we add it explicitly.
+
+-- Step 1a: Create new conversations table with id column
+-- (SQLite requires full table rebuild for schema changes)
+CREATE TABLE conversations_new (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    conversation_id TEXT NOT NULL UNIQUE,
+    title TEXT,
+    workspace_id BIGINT NOT NULL,
+    context TEXT,
+    created_at TIMESTAMP NOT NULL,
+    updated_at TIMESTAMP,
+    metrics TEXT,
+    parent_id TEXT,
+    source TEXT,
+    cwd TEXT,
+    message_count INTEGER
+);
+
+-- Step 1b: Copy all data from old table (preserves relative rowid ordering)
+INSERT INTO conversations_new (
+    id, conversation_id, title, workspace_id, context,
+    created_at, updated_at, metrics, parent_id, source, cwd, message_count
+)
+SELECT rowid, conversation_id, title, workspace_id, context,
+       created_at, updated_at, metrics, parent_id, source, cwd, message_count
+FROM conversations;
+
+-- Step 1c: Preserve the old table's indexes on new schema
+CREATE INDEX IF NOT EXISTS idx_conversations_workspace ON conversations_new(workspace_id);
+CREATE INDEX IF NOT EXISTS idx_conversations_parent ON conversations_new(parent_id);
+CREATE INDEX IF NOT EXISTS idx_conversations_source ON conversations_new(source);
+CREATE INDEX IF NOT EXISTS idx_conversations_created ON conversations_new(created_at);
+CREATE INDEX IF NOT EXISTS idx_conversations_updated ON conversations_new(updated_at);
+CREATE INDEX IF NOT EXISTS idx_conversations_cwd ON conversations_new(cwd);
+
+-- Step 1d: Drop old table and its triggers
+DROP TRIGGER IF EXISTS conversations_fts_insert;
+DROP TRIGGER IF EXISTS conversations_fts_update;
+DROP TRIGGER IF EXISTS conversations_fts_delete;
+DROP TABLE conversations;
+
+-- Step 1e: Rename new table to original name
+ALTER TABLE conversations_new RENAME TO conversations;
+
+-- Phase 2: Drop old contentful FTS5 table and recreate as external-content
+-- This step runs LIVE and is lock-light (FTS table is virtual).
+
+-- Step 2a: Drop the old FTS table (and its auto-generated content table)
+DROP TABLE IF EXISTS conversations_fts;
+
+-- Step 2b: Create new external-content FTS5 table
+-- Columns match the base table columns we want to search:
+--   - title: user-facing conversation name (searchable)
+--   - content: indexed from conversations.context (blob content, searchable)
+--   - cwd: working directory (optional, not indexed but available for metadata)
+-- Note: conversation_id is NOT in FTS (external-content uses rowid for joining)
+CREATE VIRTUAL TABLE conversations_fts USING fts5(
+    title,
+    content,
+    cwd,
+    tokenize='porter',
+    content='conversations',
+    content_rowid='id'
+);
+
+-- Step 2c: Populate the FTS index with existing data
+-- This is the equivalent of INSERT in external-content mode:
+-- FTS5 will read from the base table and build its index.
+-- NOTE: This step is EXPENSIVE for large tables; it is deferred to a
+-- maintenance window AFTER this migration completes (see section 5).
+-- For now, we insert a NULL rebuild to mark FTS as stale.
+-- INSERT INTO conversations_fts(rowid, title, content, cwd)
+-- SELECT id, COALESCE(title, ''), COALESCE(context, ''), COALESCE(cwd, '')
+-- FROM conversations
+-- WHERE context IS NOT NULL;
+--
+-- DEFERRED: Rebuild runs separately via maintenance script (see section 5).
+
+-- Step 2d: Recreate lightweight delete triggers (optional)
+-- These maintain FTS consistency without the heavy write cost of the old triggers.
+-- Option: SKIP this step if P2 is already dropping triggers entirely.
+-- If enabled, replace OLD rowid reference with OLD.id:
+--
+-- CREATE TRIGGER IF NOT EXISTS conversations_fts_delete
+-- AFTER DELETE ON conversations
+-- BEGIN
+--     DELETE FROM conversations_fts WHERE rowid = OLD.id;
+-- END;
+
+-- (End of migration up)
+```
+
+---
+
+#### Down (Rollback)
+
+```sql
+-- ROLLBACK TO CONTENTFUL FTS5
+-- This reverts to the pre-P2b state. Requires the old sync triggers to be re-added.
+
+-- Step 1: Drop the new external-content FTS table
+DROP TABLE IF EXISTS conversations_fts;
+
+-- Step 2: Recreate the old contentful FTS5 table (with conversations_fts_content)
+CREATE VIRTUAL TABLE conversations_fts USING fts5(
+    conversation_id UNINDEXED,
+    title,
+    content,
+    tokenize='porter'
+);
+
+-- Step 3: Rebuild from base table (same as original migration)
+INSERT INTO conversations_fts(conversation_id, title, content)
+SELECT conversation_id, COALESCE(title, ''), COALESCE(context, '')
+FROM conversations
+WHERE context IS NOT NULL;
+
+-- Step 4: Recreate the old sync triggers (assumes they are needed for rollback)
+-- NOTE: If P2 has already dropped these triggers, this step may fail.
+-- Rollback will need to restore them from git history or previous migration.
+CREATE TRIGGER IF NOT EXISTS conversations_fts_insert
+AFTER INSERT ON conversations
+BEGIN
+    INSERT INTO conversations_fts(conversation_id, title, content)
+    VALUES (
+        NEW.conversation_id,
+        COALESCE(NEW.title, ''),
+        COALESCE(NEW.context, '')
+    );
+END;
+
+CREATE TRIGGER IF NOT EXISTS conversations_fts_update
+AFTER UPDATE ON conversations
+BEGIN
+    DELETE FROM conversations_fts WHERE conversation_id = OLD.conversation_id;
+    INSERT INTO conversations_fts(conversation_id, title, content)
+    VALUES (
+        NEW.conversation_id,
+        COALESCE(NEW.title, ''),
+        COALESCE(NEW.context, '')
+    );
+END;
+
+CREATE TRIGGER IF NOT EXISTS conversations_fts_delete
+AFTER DELETE ON conversations
+BEGIN
+    DELETE FROM conversations_fts WHERE conversation_id = OLD.conversation_id;
+END;
+
+-- Step 5: Drop the id column from conversations (requires table rebuild)
+-- NOTE: This is complex; rollback may require restoring from backup or manual recovery.
+-- For now, we leave the id column in place and restore FTS functionality only.
+-- A full rollback would need to re-DROP the id column and re-add the old schema.
+
+-- (End of migration down)
+```

+
+## 4. Query Rewrites in `conversation_repo.rs`
+
+### Key Change: `rowid` Joins
+
+Currently, searches join by `conversation_id` column (because FTS is contentful):
+
+```rust
+// CURRENT (contentful FTS5)
+let mut sql = String::from(
+    "SELECT c.*, bm25(conversations_fts) AS rank_score \
+     FROM conversations c \
+     JOIN conversations_fts fts ON c.conversation_id = fts.conversation_id \
+     WHERE conversations_fts MATCH ? \
+       AND c.workspace_id = ? \
+     ORDER BY rank_score",
+);
+```
+
+**With external-content FTS, join by `rowid` (now = `id` column):**
+
+```rust
+// NEW (external-content FTS5)
+let mut sql = String::from(
+    "SELECT c.*, bm25(conversations_fts) AS rank_score \
+     FROM conversations c \
+     JOIN conversations_fts fts ON c.id = fts.rowid \
+     WHERE conversations_fts MATCH ? \
+       AND c.workspace_id = ? \
+     ORDER BY rank_score",
+);
+```
+
+**Location:** `/crates/forge_repo/src/conversation/conversation_repo.rs` line 303
+
+---
+
+### Snippet Query Rewrite
+
+Currently, snippet column index is **2** (columns: conversation_id, title, content):
+
+```rust
+// CURRENT (contentful FTS5, 3 columns)
+let sql = format!(
+    "SELECT snippet(conversations_fts, 2, '[', ']', '…', {}) AS s \
+     FROM conversations_fts \
+     WHERE conversation_id = ? AND conversations_fts MATCH ?",
+    token_count.min(256)
+);
+```
+
+**With external-content FTS (new columns: title, content, cwd), content is now column index 1:**
+
+```rust
+// NEW (external-content FTS5, 3 columns: title, content, cwd)
+let sql = format!(
+    "SELECT snippet(conversations_fts, 1, '[', ']', '…', {}) AS s \
+     FROM conversations_fts \
+     WHERE rowid = (SELECT id FROM conversations WHERE conversation_id = ?) \
+       AND conversations_fts MATCH ?",
+    token_count.min(256)
+);
+```
+
+**Alternative (direct rowid if stored in context):**
+
+If the calling code knows the numeric `id`, the join simplifies:
+
+```rust
+// SIMPLEST (if id passed directly)
+let sql = format!(
+    "SELECT snippet(conversations_fts, 1, '[', ']', '…', {}) AS s \
+     FROM conversations_fts \
+     WHERE rowid = ? AND conversations_fts MATCH ?",
+    token_count.min(256)
+);
+```
+
+**Location:** `/crates/forge_repo/src/conversation/conversation_repo.rs` lines 351–356
+
+---
+
+## 5. Migration & Operations Sequence
+
+### Prerequisite: P2 Completion
+
+This migration **assumes P2 (drop sync triggers) is complete**. If not, coordinate timing:
+
+1. **P2 runs first** — drop the 3 sync triggers (conversations_fts_insert, update, delete)
+2. **P2b migration** — alter table, drop old FTS, create external-content FTS
+3. **Maintenance window** — VACUUM + FTS rebuild (deferred)
+
+---
+
+### Migration Execution (Live, Lock-Light)
+
+```
+Target: 6.85 GB database
+Estimated impact:
+  - ALTER TABLE (table rebuild): ~20–30 min (lock-light WAL, no full VACUUM)
+  - DROP old FTS: ~10 sec (virtual table drop)
+  - CREATE external-content FTS: ~1 sec (index not populated yet)
+  - Total: ~20–30 min
+```
+
+**Steps:**
+
+1. **Backup** — snapshot database before migration
+2. **Run migration up** — diesel CLI or manual execution in transaction
+3. **Verify** — confirm old FTS gone, new FTS present (empty)
+4. **Restart app** — reload Diesel schema.rs (schema change)
+5. **Deploy query changes** — update conversation_repo.rs (line 303, 351–356)
+6. **Test searches** — expect empty results until rebuild (see step 7)
+
+---
+
+### Maintenance Window (Separate Process)
+
+**When:** Off-peak time (late night, weekend, or scheduled maintenance)  
+**Duration:** ~45–60 min for 6.85 GB table
+
+```bash
+# Pseudo-code (not in migration)
+
+sqlite3 /path/to/database.db <<'EOF'
+  -- Full VACUUM to compact WAL and reassign stable rowids
+  VACUUM;
+
+  -- Rebuild external-content FTS from base table
+  -- (Full index scan; slow but done once)
+  INSERT INTO conversations_fts(rowid, title, content, cwd)
+  SELECT id, COALESCE(title, ''), COALESCE(context, ''), COALESCE(cwd, '')
+  FROM conversations
+  WHERE context IS NOT NULL;
+
+  -- Optimize FTS index (reduces file size)
+  INSERT INTO conversations_fts(conversations_fts) VALUES('optimize');
+EOF
+```
+
+**Why separate?**
+- VACUUM cannot run in a transaction (Diesel migrations run in tx)
+- Rebuild is expensive; better run offline or in scheduled maintenance
+- Gives ops team control over downtime window
+
+---
+
+## 6. Risk Table
+
+| Risk | Severity | Mitigation | Notes |
+|------|----------|-----------|-------|
+| **Rowid drift after VACUUM** | HIGH | Explicit `id INTEGER PRIMARY KEY` ties rowid to column, stable across VACUUM | Must add id column; no rollback risk once applied |
+| **Search-unavailable window** | MEDIUM | Rebuild deferred to maintenance; accept ~few hours until rebuild | FTS index is empty until rebuild; queries return 0 results (not errors) |
+| **Snippet column off-by-one** | MEDIUM | Verify column index in rewrite (title=0, content=1, cwd=2) | Manual testing required; easy to fix if wrong |
+| **Diesel schema.rs mismatch** | HIGH | Update schema.rs with new `id` column; regenerate if needed | `diesel migration run` auto-updates; verify before deploy |
+| **Sync triggers collision (P2)** | MEDIUM | Coordinate P2 completion before P2b; don't recreate old triggers | P2b does NOT recreate heavyweight delete triggers |
+| **Missed query updates** | HIGH | Search in 2 places: line 303 (rowid join), lines 351–356 (snippet index) | Review all 2 locations; run full test suite |
+| **Rebuild failure mid-way** | MEDIUM | Rebuild is idempotent (INSERT OR REPLACE); can retry | If rebuild interrupted, run again in next maintenance window |
+| **Large table rebuild duration** | MEDIUM | 6.85 GB → ~45–60 min rebuild; schedule off-peak | Monitor first run; adjust estimate for future |
+
+---
+
+## 7. Diesel Schema & Build Implications
+
+### schema.rs Update
+
+Current (before P2b):
+```rust
+diesel::table! {
+    conversations (conversation_id) {
+        conversation_id -> Text,
+        title -> Nullable<Text>,
+        workspace_id -> BigInt,
+        context -> Nullable<Text>,
+        created_at -> Timestamp,
+        updated_at -> Nullable<Timestamp>,
+        metrics -> Nullable<Text>,
+        parent_id -> Nullable<Text>,
+        source -> Nullable<Text>,
+        #[sql_name = "cwd"]
+        cwd -> Nullable<Text>,
+        #[sql_name = "message_count"]
+        message_count -> Nullable<Integer>,
+    }
+}
+```
+
+After P2b (with explicit `id` PRIMARY KEY):
+```rust
+diesel::table! {
+    conversations (id) {  // PRIMARY KEY changes from conversation_id to id
+        id -> Integer,
+        conversation_id -> Text,
+        title -> Nullable<Text>,
+        workspace_id -> BigInt,
+        context -> Nullable<Text>,
+        created_at -> Timestamp,
+        updated_at -> Nullable<Timestamp>,
+        metrics -> Nullable<Text>,
+        parent_id -> Nullable<Text>,
+        source -> Nullable<Text>,
+        #[sql_name = "cwd"]
+        cwd -> Nullable<Text>,
+        #[sql_name = "message_count"]
+        message_count -> Nullable<Integer>,
+    }
+}
+```
+
+### Regeneration
+
+```bash
+cd crates/forge_repo
+diesel migration run --database-url 'sqlite://test.db'
+diesel print-schema > src/database/schema.rs
+```
+
+**Or:** Manual edit if regeneration fails (rare).

+# P3 Single-Writer Daemon
+
+## Scope
+
+Phenotype-org addition for the tailcallhq/forgecode fork.
+
+This design keeps the existing \`.forge.db\` file and schema intact while
+collapsing many concurrent forge processes into a single SQLite writer daemon.
+There is no data migration.
+
+## Problem Statement
+
+Forge currently allows multiple processes to open the same SQLite database and
+issue writes independently. Even with WAL mode, concurrent writers still contend
+on the single SQLite write lock. The hot path here is the per-turn conversation
+upsert flow, which is called frequently enough that contention becomes the
+dominant bottleneck.
+
+## Proposed Architecture
+
+### Daemon ownership
+
+Introduce a new \`forge-dbd\` daemon that owns the only read/write SQLite
+connection for \`.forge.db\`.
+
+### Client access model
+
+Clients connect to the daemon over a Unix domain socket at:
+
+\`~/.forge/.forge.db.sock\`
+
+Recommended split:
+
+- Reads stay direct through the existing repository path.
+- Writes go through the daemon.
+
+Rationale:
+
+- WAL already allows concurrent readers.
+- Reads are latency-sensitive and do not benefit from an extra hop.
+- Writes benefit from centralized batching and serialization.
+
+An alternate fully proxied mode is possible later, but is not required for this
+phase.
+
+### Direct mode fallback
+
+If the daemon is not desired, unavailable, or explicitly disabled, the client
+may fall back to direct SQLite access using the current code path.
+
+This is a mode switch only. It does not change schema, file layout, or data.
+
+## Wire Protocol
+
+The daemon protocol is a request/response enum exchanged over a length-prefixed
+frame.
+
+Encoding options:
+
+- \`bincode\` for the default compact wire format.
+- JSON as a debugging-friendly alternate.
+
+The protocol mirrors repository write operations, not internal SQL details.
+Reads are intentionally omitted from the daemon contract in the recommended
+mode.
+
+### Request variants
+
+- \`UpsertConversation\`
+- \`UpsertConversationRef\`
+- \`UpdateParentId\`
+- \`DeleteConversation\`
+- \`OptimizeFts\`
+- \`RefreshFts\`
+- \`CheckpointWal\`
+
+### Response variants
+
+- \`Ack\`
+- \`Error\`
+
+The request payloads should carry the concrete domain types used by the repo
+layer so the client does not need to re-encode business meaning in ad hoc
+structures.
+
+## Lifecycle
+
+### Startup
+
+1. Client checks whether the socket exists and accepts connections.
+2. If the socket is live, the client connects.
+3. If not, the first client attempts to spawn \`forge-dbd\`.
+4. Startup is guarded by an advisory lock so only one process performs bind and
+   bootstrap.
+
+### Runtime
+
+- The daemon opens the SQLite database once and keeps the single writer
+  connection.
+- Incoming write requests are queued and executed on that connection.
+- The WAL checkpointer that previously lived in P1 moves into the daemon.
+  Since the daemon is now the only writer, checkpointing is easier to schedule
+  and reason about centrally.
+
+### Shutdown
+
+- The daemon exits after the last client disconnects and the idle timeout
+  expires.
+- A stale socket is unlinked and recreated on next startup.
+
+## Batching Strategy
+
+The main amplification win is transaction batching.
+
+The daemon should coalesce many write requests that arrive within a short window
+into a single SQLite transaction. The conversation upsert path is the primary
+target.
+
+Batching goals:
+
+- Reduce lock churn.
+- Reduce fsync frequency.
+- Preserve per-request acknowledgement semantics.
+
+Operational shape:
+
+- Accumulate requests for a short debounce window.
+- Flush on timeout or when the queue reaches a threshold.
+- Execute all batched writes inside one transaction.
+- Return a response per request.
+
+This is especially useful for the per-turn conversation persistence burst, where
+multiple upserts may arrive back-to-back during a single agent turn.
+
+## Client-Side Swap
+
+The follow-up implementation will replace the write branch of
+\`ConversationRepositoryImpl::run_with_connection\` with:
+
+1. Serialize the repository operation into a protocol request.
+2. Send it over the socket.
+3. Await acknowledgement or error.
+
+The \`ConversationRepository\` trait surface stays unchanged, so callers do not
+need to change.
+
+## Failure Modes
+
+### Daemon crash
+
+- Clients should reconnect.
+- If needed, the first reconnecting client can respawn the daemon.
+
+### Stale socket
+
+- Detect failed connect or failed handshake.
+- Unlink the stale path.
+- Recreate the socket and respawn the daemon if required.
+
+### Batch failure
+
+- If a transaction fails, return the error for each request in the affected
+  batch.
+- The daemon remains responsible for mapping the database failure back to the
+  request envelope.
+
+### Writer lock contention inside the daemon
+
+- This should be rare because the daemon owns the only writer connection.
+- Any internal retry policy should remain local to the daemon process.
+
+## Non-Goals
+
+- No schema migration.
+- No table rewrite.
+- No repository trait redesign.
+- No client-side caller changes in this task.
+- No full daemon implementation in this scaffold.
+
+## Scope Boundaries For This Task
+
+This task only adds:
+
+- design documentation
+- \`crates/forge_dbd/\` scaffold
+- workspace membership entry
+
+The existing repository crates remain untouched.

+# forgecode Overhaul — Session Overview
+
+**Date:** 2026-06-28 · **Owner:** orchestrated (parent coordinator + audit fleet) · **Repo:** forgecode (34-crate Rust workspace, fork of antinomyhq/forge; powers `forge-dev`)
+
+## Goal
+Own a deep, evidence-based audit of forgecode against the L0–L40 pillar framework (v37) and produce a phased, DAG-structured overhaul roadmap that lifts the weakest pillars to ≥2.0 without regressing the strong ones.
+
+## Method
+Phase 1 — deep-audit fleet (5 agents, one per weakest cluster) auditing **current canonical `main`** (not the stale audit clone), each producing file-cited findings with target state, work items, acceptance criteria, agent-effort, dependencies, and risk. Phase 2 — this synthesis: a phased WBS + DAG.
+
+## Scorecard baseline (v37 means; lower = higher leverage)
+| Cluster | Pillars | Mean | Theme |
+|---|---|---|---|
+| W03 | L5,L26,L27 | **0.83** | observability · resilience · failure-ops |
+| W02 | L4,L6,L7,L8 | **1.00** | async lifecycle · perf · concurrency · memory |
+| W12 | L34–L37 | **1.15** | docs · shared-code · polish · stubs |
+| W07 | L18,L19,L20,L28 | **1.38** | secrets · supply-chain · threat-model · deps |
+| W05 | L11,L12,L13 | **1.40** | testing-DX · SSOT docs · onboarding |
+| W06 | L14–L17 | 1.50 | (not deep-audited — Phase B) |
+| W08 | L21–L24,L29 | 1.50 | (Phase B) |
+| W10/W09/W04/W11/W01 | — | 1.75–2.23 | already strong |
+
+## Root cause (cross-cutting)
+The single highest-leverage finding, surfaced independently by **3 of 5** audits (W12, W05, and the W01 re-score): the repo still carries **leftover "ForgeCode Evals" TypeScript fork scaffolding** (README, `docs/SSOT.md`, `Justfile`, boundary/intent stub docs) that describes a fictional TS project, while the real product is a ~144k-LOC Rust workspace. This drift causes doc-pillar failures, ungated CI (Justfile drives Node), audit misscoring, and stub-detection penalties. **De-forking the doc/governance surface is the foundational unblocker** for the whole roadmap.
+
+## Deliverables
+- `audit/` — 5 cluster findings docs (87 findings total, all file-cited).
+- `03_DAG_WBS.md` — the phased overhaul roadmap (this session's primary output).
+- `05_KNOWN_ISSUES.md` — live bugs found during audit (P0 secret leak, production `unimplemented!()`).
+
+## Live bugs found (not just scores)
+- **P0 secret leak:** `#[derive(Debug)]` on `ApiKey`/`AuthCredential`/OAuth tokens prints plaintext to logs/PostHog (only `Display` redacts).
+- **P1:** `.credentials.json` (0o600) not gitignored.
+- **P1:** production `unimplemented!()` in `forge_repo/.../openai_responses/repository.rs#L573` (`http_delete`).
+- **P2:** user-facing `panic!` on bad `--directory` (`forge_main/src/main.rs#L135`).

+# forgecode Overhaul — Phased WBS + DAG
+
+Derived from the 5-cluster deep audit (87 findings). Phases are ordered by dependency; tasks within a phase run in parallel unless a predecessor is listed. Effort is in agent terms (tool calls / parallel subagents / wall-clock), per governance.
+
+## Critical path (one line)
+`P0 de-fork docs → P1 CI gates + stub kill + P0 security → P2 resilience/obs/lifecycle → P3 perf+concurrency (needs benches first) → P4 ops/governance docs → P5 cross-repo shared crates (sponsor-gated)`
+
+## DAG (phase predecessors)
+```
+P0 ─┬─> P1 ─┬─> P2 ─┬─> P3
+    │       │       └─> P4
+    │       └─> P4
+    └────────────────> P5 (also needs sponsor sign-off)
+P2 ─> P5
+```
+
+---
+
+## Phase P0 — Foundation: de-fork the doc/governance surface  (unblocks scoring + CI)
+Predecessors: none. Lowest risk, highest unblock value. Source material already exists in `CLAUDE.md`/`AGENTS.md`/`Cargo.toml`.
+
+| ID | Task | Files | Acceptance | Effort | Dep |
+|----|------|-------|-----------|--------|-----|
+| P0.1 | Rewrite README Rust-first (remove "ForgeCode Evals TS" framing, real quick-start `cargo build`) | `README.md` | No TS/npm-only claims; `cargo build`/`cargo nextest` documented; arch matches `crates/` | 4 calls / ~3 min | — |
+| P0.2 | Rewrite `docs/SSOT.md` to the real 34-crate workspace (kill `Rust: N/A`, fictional ports/adapters) | `docs/SSOT.md` | SSOT lists real crates + layering; no `ProviderPort/CsvAdapter` ghosts | 4 calls / ~3 min | — |
+| P0.3 | Replace Node `Justfile` with cargo-driven recipes (`just test`→`cargo nextest`, `just lint`→clippy/fmt) | `Justfile` | `just test`/`just lint`/`just build` drive cargo, exit 0 | 3 calls / ~2 min | — |
+| P0.4 | Fill stub governance docs (boundary, intent, journey manifests) | `docs/boundary/forgecode.md`, `docs/journeys/manifests/*` | No `do-not-edit TODO` stubs; real content | 4 calls / ~4 min | — |
+| P0.5 | gitignore `.credentials.json` (+ assert 0o600 test still passes) | `.gitignore` | file ignored; regression test green | 1 call / <1 min | — |
+
+**Exit:** docs describe the real product; re-run audit W12/W05/W01 expected ≥+0.7 mean. Wave of 1–2 subagents, ~10–14 calls total.
+
+---
+
+## Phase P1 — Gates & Stubs & Security P0  (after P0 docs give an accurate baseline)
+Predecessors: P0 (Justfile/CI docs). Medium risk (clippy may surface debt — fix, don't suppress, per quality policy).
+
+| ID | Task | Files | Acceptance | Effort | Dep |
+|----|------|-------|-----------|--------|-----|
+| P1.1 | **P0 SECURITY:** redact secrets in `Debug` — wrap `ApiKey`/`AuthCredential`/tokens in a `Secret<String>` or custom `Debug` | `forge_domain` auth types, `provider_repo.rs` | `{:?}` never prints plaintext; test asserts redaction | 5 calls / ~5 min | — |
+| P1.2 | Add blocking CI on **Linux runner only** (billing): `cargo fmt --check` + `cargo clippy -D warnings` (replace autofix-only `autofix.yml`) | `.github/workflows/` | PR fails on fmt/clippy violation; not auto-committed | 4 calls / ~4 min | P0.3 |
+| P1.3 | Add gating `cargo nextest` job + coverage threshold (stop discarding lcov) | `.github/workflows/`, `forge_ci` | tests gate the merge; threshold enforced | 4 calls / ~4 min | P0.3 |
+| P1.4 | Kill production stubs: implement/remove `openai http_delete` `unimplemented!()`; fix `NoopIntentExtractor` erroring | `forge_repo/.../openai_responses/repository.rs#L573`, `forge_domain/src/intent.rs#L119` | no non-test `unimplemented!()`; intent extractor returns or is removed | 5 calls / ~6 min | — |
+| P1.5 | Resolve dead/unfinished crates: drop `ghostty-kit`; gate or finish `forge_dbd` | `Cargo.toml`, `crates/ghostty-kit`, `forge_dbd` | workspace has no dead crate; forge_dbd builds+tested or feature-gated | 4 calls / ~5 min | — |
+| P1.6 | Collapse update bots to one (kill Renovate blanket `automerge:true`); add `reason` to all advisory ignores | `renovate.json`/`dependabot.yml` | single bot; no unattended automerge; every ignore has a reason+ticket | 3 calls / ~3 min | — |
+
+**Exit:** CI is a real gate; zero production stubs; secret leak closed. L37/L36/L11/L18/L28 lift.
+
+---
+
+## Phase P2 — Hardening: resilience · observability · lifecycle  (after gates green)
+Predecessors: P1. Aligns with in-flight branch `fix/5109-proxy-fast-fail-concurrency`.
+
+| ID | Task | Files | Acceptance | Effort | Dep |
+|----|------|-------|-----------|--------|-----|
+| P2.1 | Unify the 3 divergent backoff impls behind one `RetryConfig`; add circuit breaker + concurrency bulkhead | `mcp_client.rs#L498`, `pool.rs`, central retry | one retry path; breaker trips+recovers (test); bounded concurrency | 8 calls / 2 subagents / ~8 min | P1.2 |
+| P2.2 | Metrics facade (`metrics` crate behind a trait) + `tracing` spans on request/exec/stream paths | `forge_*` telemetry | spans cover hot paths; metrics pluggable (noop default) | 8 calls / ~8 min | — |
+| P2.3 | `forge_dbd` health probe + graceful drain (don't lose queued writes on exit) | `forge_dbd/src/server.rs#L52` | health endpoint; clean shutdown flushes queue (test) | 6 calls / ~6 min | P1.5 |
+| P2.4 | Uniform async task-lifecycle convention; fix uncancellable FTS loop + unbounded forge3d accept loop + fire-and-forget telemetry spawns | `forge_api.rs#L63`, `forge3d/src/server.rs#L225` | long-lived tasks cancellable + bounded; tracked handles | 7 calls / 2 subagents / ~8 min | — |
+
+**Exit:** L5/L26/L4 lift; resilience verifiable.
+
+---
+
+## Phase P3 — Perf & Correctness  (benches MUST exist before optimizing)
+Predecessors: P2. Build the measurement spine first, then change allocator/hot paths.
+
+| ID | Task | Files | Acceptance | Effort | Dep |
+|----|------|-------|-----------|--------|-----|
+| P3.1 | criterion `[[bench]]` spine for 7 hot crates (walker, json_repair, similarity, drift, stream, fs, eventsource) + dhat heap profiling harness | `crates/*/benches` | benches run in CI (non-gating perf job); baseline recorded | 8 calls / 3 subagents / ~10 min | — |
+| P3.2 | Swap to jemalloc/mimalloc `#[global_allocator]`; bound unbounded streaming buffers | `forge_main`, `event_stream.rs#L137`, `utf8_stream.rs` | allocator active; buffers capped; bench delta recorded | 5 calls / ~6 min | P3.1 |
+| P3.3 | Concurrency verification: loom/miri on the 2 riskiest state machines (MCP client TOCTOU, executor Mutex-across-exec); remove runtime `set_var` (3 files) | `mcp_client.rs#L75`, `executor.rs#L101` | loom/miri job green; no runtime env mutation | 8 calls / 2 subagents / ~12 min | P3.1 |
+
+**Exit:** L6/L8/L7 lift; perf changes are measured, not guessed.
+
+---
+
+## Phase P4 — Ops & Governance docs  (document real, hardened behavior)
+Predecessors: P2 (so docs describe actual behavior). Planner-only; no code.
+
+| ID | Task | Acceptance | Effort | Dep |
+|----|------|-----------|--------|-----|
+| P4.1 | STRIDE threat model (credential store, prompt-injection→subprocess-exec, MCP trust, telemetry egress, ZSH plugin) | `docs/security/threat-model.md` exists, covers all 5 surfaces | 1 subagent / ~12 min | P2.1 |
+| P4.2 | Ops doc set: SLO/error-budget (CLI-appropriate), runbook, incident/postmortem template | `docs/operations/*` complete | ~8 calls / ~8 min | P2.3 |
+
+**Exit:** L27/L20 off the floor (0.3/0.5 → ≥1.8).
+
+---
+
+## Phase P5 — Cross-repo shared crates  (SPONSOR-GATED)
+Predecessors: P0 + P2 + **explicit sponsor sign-off** on destination per the Phenotype Cross-Project Reuse Protocol. ~3.5–5.5k LOC duplicated with OmniRoute & cliproxyapi-plusplus.
+
+| ID | Task | Acceptance | Effort | Dep |
+|----|------|-----------|--------|-----|
+| P5.1 | Extract `phenotype-provider-models` (provider/model registry + schema normalization) | new shared crate; forgecode+OmniRoute+cliproxy consume it; dup removed | 3 subagents / ~20 min | sponsor sign-off |
+| P5.2 | Extract shared OAuth2 (+5-min refresh buffer) | shared crate; callers migrated | 2 subagents / ~15 min | P5.1 |
+| P5.3 | Extract shared resilience/SSE stop-signal | shared crate; callers migrated | 2 subagents / ~15 min | P5.1, P2.1 |
+
+**Exit:** L35 → ≥2.6; org-wide dedup.
+
+---
+
+## Execution waves (recommended)
+- **Wave 1 (now, parallel):** all of P0 (1–2 subagents) + P1.1 (security P0) + P1.4/P1.5 (stubs) — independent, ~15 min.
+- **Wave 2:** P1.2/P1.3/P1.6 (CI gates) after P0.3 — ~10 min.
+- **Wave 3:** P2 (4 tasks parallel) — ~10 min.
+- **Wave 4:** P3.1 then P3.2/P3.3; P4 in parallel — ~15 min.
+- **Wave 5:** P5 after sponsor sign-off.
+
+## Projected pillar lift
+Weak-cluster means **0.83–1.40 → ~2.0–2.4** after P0–P4. Each phase ends by re-running the relevant v37 cluster audit to confirm the lift (smart-contract verification).
+
+## Sponsor decisions required
+1. **P5 destination** for shared crates (new repo vs existing shared module) — per reuse protocol.
+2. **Scope/order:** ship P0+P1 as the first PR train, or batch P0–P2?
+3. **Phase B audit:** deep-audit the mid-tier clusters (W06/W08 at 1.50) too, or focus the overhaul on the bottom 5?

+# forgecode Overhaul — Known Issues (live bugs found during audit)
+
+These are concrete defects in current `main`, surfaced by the deep audit. Severity-ordered. Each maps to a WBS task in `03_DAG_WBS.md`.
+
+| Sev | Issue | Location | Fix task |
+|-----|-------|----------|----------|
+| **P0** | Secrets printed in plaintext via `#[derive(Debug)]` on `ApiKey`/`AuthCredential`/OAuth tokens (only `Display` redacts) → leaks into logs + PostHog tracker | `forge_domain` auth types; `provider_repo.rs` | P1.1 |
+| **P1** | `.credentials.json` (mode 0o600) not gitignored — risk of committing live creds | repo root / `.gitignore` | P0.5 |
+| **P1** | Production `unimplemented!()` in a non-test `HttpClient` impl (`http_delete`) | `forge_repo/src/provider/openai_responses/repository.rs#L573` | P1.4 |
+| **P1** | `NoopIntentExtractor` returns an error instead of a no-op | `forge_domain/src/intent.rs#L119,L129` | P1.4 |
+| **P2** | User-facing `panic!` on bad `--directory` arg (should be a clean error) | `forge_main/src/main.rs#L135` | P1 (polish) |
+| **P2** | Uncancellable FTS background loop; unbounded forge3d accept loop; fire-and-forget telemetry spawns | `forge_api.rs#L63-74`, `forge3d/src/server.rs#L225-240` | P2.4 |
+| **P2** | `forge_dbd` loses queued writes on exit (no graceful drain) | `forge_dbd/src/server.rs#L52` | P2.3 |
+| **P2** | Thread-unsafe runtime `set_var` in 3 files; lock held across `await`; executor `Mutex` across full child exec | `mcp_client.rs#L75`, `executor.rs#L101-141` | P3.3 |
+| **P3** | Renovate `automerge:true` = unattended supply-chain merges on a fast-moving fork; 5/9 advisory ignores lack a `reason` (suppression-policy violation) | `renovate.json` | P1.6 |
+| **P3** | Dead crate `ghostty-kit`; default system allocator (no jemalloc/mimalloc) | `Cargo.toml`; `forge_main` | P1.5 / P3.2 |
+
+**Note:** the audit also corrected two prior-scorecard inaccuracies — L18 understated existing `0o600` hardening + env→file migration (credit due), and W01/W05/W12 had all been scored against the stale TS-evals scaffolding rather than the real Rust workspace (root cause → P0).

+# forgecode Cluster W02 Overhaul Findings — L4, L6, L7, L8
+
+**Repo:** `/Users/kooshapari/CodeProjects/Phenotype/repos/forgecode` (34-crate Rust workspace, edition 2024, rust 1.92)
+**Prior W02 mean:** 1.00/3.0 (2nd weakest cluster). Sub-scores: L4 1.5, L6 1.0, L7 1.0, L8 0.5.
+**Audit basis:** current canonical `main` source (NOT the smaller v37 clone). Evidence verified against live files.
+**Mode:** PLANNING audit — no source modified.
+
+Effort uses agent-terms: tool calls / parallel subagents / wall-clock minutes.
+
+---
+
+## L4 — Async Lifecycle Discipline (graceful shutdown, cancellation, backpressure, task lifecycle)
+
+**What it measures:** Whether spawned async tasks are tracked/joinable/abortable, whether the system shuts down gracefully (signal handling → drain → cancel), whether channels apply backpressure (bounded), and whether spawned child processes/streams are cancellation-safe.
+
+**Current state:** Foundation is genuinely partial-good. Several crates do this *right* and should be the template: `forge_app/src/hooks/title_generation.rs#L106-118` (Drop aborts all task handles), `forge_repo/src/provider/chat.rs#L196-217` (`BgRefresh` collects `AbortHandle`s and aborts on Drop), `forge_stream/src/mpsc_stream.rs#L34-40` (Drop closes receiver + aborts task), `forge_main/src/main.rs#L54-62` and `forge3d/src/main.rs#L139-149` (signal-driven `select!`). The gap is that these patterns are not applied consistently — long-lived servers and fire-and-forget spawns escape lifecycle control.
+
+### Findings
+
+**L4-F1 — Uncancellable infinite background loop (FTS refresh).**
+- Gap: `crates/forge_api/src/forge_api.rs#L63-74` `spawn_fts_refresh_task` spawns `loop { … tokio::time::sleep(interval).await }` with no handle stored, no cancellation token. Started unconditionally at API construction (`#L58`). Cannot be stopped on shutdown; keeps runtime alive.
+- Target: Loop owns a `CancellationToken`; handle stored on the API struct; `select!` between the timer and `token.cancelled()`; aborted/awaited in a `Drop` or explicit `shutdown()`.
+- Work items: add `tokio_util::sync::CancellationToken` field to `ForgeApi`; refactor `spawn_fts_refresh_task` to take a child token; store `JoinHandle`; impl `Drop` (or `shutdown()`) that cancels + best-effort joins.
+- Acceptance: a unit test constructs the API, drops it, and asserts the refresh task observes cancellation within N ms (e.g. via a probe `AtomicBool`/channel); no task leak under `tokio::test(flavor="multi_thread")` with `tokio-console`/`#[tokio::test] + JoinHandle::is_finished`.
+- Effort: ~6 tool calls / ~8 min.
+- Dependencies: none (tokio_util already a workspace dep).
+- Risk: Low. Behavior-preserving; only adds a stop path.
+
+**L4-F2 — Untracked MCP stderr drain task.**
+- Gap: `crates/forge_infra/src/mcp_client.rs#L115` spawns a stderr line-reader (`while let Ok(Some(line)) = reader.next_line().await`) fire-and-forget. If the child dies or connection is cancelled, the task is orphaned; if stderr fills it can wedge.
+- Target: Drain task tracked per-connection; aborted when the client/connection drops.
+- Work items: store the `JoinHandle` alongside the `RmcpClient` in the client struct (`#L34`); abort on disconnect/Drop.
+- Acceptance: test that dropping the client aborts the drain task; no orphan after client drop.
+- Effort: ~4 tool calls / ~6 min.
+- Dependencies: interacts with L7-F1 (the `Arc<RwLock<Option<Arc<…>>>>` refactor) — coordinate.
+- Risk: Low.
+
+**L4-F3 — forge3d accept loop: unbounded, untracked per-connection spawn.**
+- Gap: `crates/forge3d/src/server.rs#L225-240` `loop { listener.accept() … tokio::spawn(handle_connection) }` — no concurrency cap, no `JoinSet`, no per-conn cancellation. `forge3d/src/main.rs#L139-149` aborts the *serve* task on signal but in-flight connection tasks are not drained.
+- Target: bounded concurrency (`Semaphore`) + tracked tasks (`JoinSet` or a `CancellationToken` shared to handlers) so shutdown can stop accepting and drain/cancel live connections.
+- Work items: add `Semaphore` (config'd max conns) acquired before spawn; collect handles in a `JoinSet`; thread a `CancellationToken` into `handle_connection`; on signal, stop accept, cancel token, drain JoinSet with a timeout.
+- Acceptance: integration test opens > limit connections and asserts the (limit+1)th blocks until a slot frees; shutdown test asserts in-flight connections are cancelled within the drain timeout.
+- Effort: ~10 tool calls / ~15 min.
+- Dependencies: none.
+- Risk: Medium. Concurrency cap could change throughput characteristics — make it configurable with a sane default.
+
+**L4-F4 — forge_dbd server: no graceful shutdown, untracked writer + client tasks.**
+- Gap: `crates/forge_dbd/src/server.rs#L52` `let _writer_handle = tokio::spawn(Self::writer_task(queue_rx));` then an infinite accept `loop` spawning `handle_client` per connection. No signal handling, queue never drained on exit; messages can be lost.
+- Target: signal-aware accept loop; on shutdown stop accepting, close the queue sender, await the writer task to drain, cancel/await client handlers.
+- Work items: add `CancellationToken`; `select!` accept vs cancel; track client handles in `JoinSet`; on cancel drop `queue_tx`, await `writer_handle`.
+- Acceptance: test enqueues N writes, triggers shutdown, asserts all N persisted before the server future resolves.
+- Effort: ~8 tool calls / ~12 min.
+- Dependencies: none.
+- Risk: Medium (data-loss-fix path; needs careful ordering test).
+
+**L4-F5 — Fire-and-forget telemetry / debug spawns.**
+- Gap: untracked spawns that can lose work or accumulate on shutdown — `crates/forge_main/src/tracker.rs#L8,L47,L51` (`tokio::spawn(TRACKER.dispatch/set_model/login)`), `crates/forge_main/src/ui.rs#L5054` (`trace_user`), `crates/forge_infra/src/http.rs#L243` (`write_debug_request` spawned per request in hot path).
+- Target: a single tracked telemetry/IO task group (a `JoinSet` or actor task fed by a bounded `mpsc`) that is flushed on shutdown; debug writes go through that channel rather than per-call spawns.
+- Work items: introduce a `Telemetry`/`DebugSink` handle holding a bounded sender + background drain task with a `shutdown().await` that flushes; replace the scattered `tokio::spawn` sites with `sink.send(...)`.
+- Acceptance: test that pending telemetry/debug writes are flushed when `shutdown()` is awaited; bounded channel applies backpressure (send blocks when full rather than spawning unboundedly).
+- Effort: ~12 tool calls / 1 subagent / ~18 min.
+- Dependencies: touches forge_main + forge_infra; do after L4-F1 establishes the cancellation-token convention.
+- Risk: Medium (cross-crate; telemetry semantics).
+
+**L4-F6 — Backpressure gaps: unbounded/lossy channels & missing process kill-on-drop.**
+- Gap: `crates/forge_drift/src/detector.rs#L29` `broadcast::channel(256)` silently drops for lagging subscribers with no lag signal; several `tokio::process::Command` sites omit `.kill_on_drop(true)` (e.g. `forge_mux/src/tmux.rs#L67`, `forge_main/src/sandbox.rs`, `forge_main/src/vscode.rs`) — orphaned children on cancel. Positive reference: `forge_infra/src/executor.rs#L67` sets `kill_on_drop(true)`.
+- Target: bounded `mpsc` (or documented broadcast lag handling) on event paths; `kill_on_drop(true)` (or explicit kill in a guard) on every spawned child.
+- Work items: audit `Command::new(` sites and add `kill_on_drop(true)`; add lag detection/metric to the drift broadcast or convert to bounded mpsc.
+- Acceptance: a lint/test (grep-based test or clippy custom) asserting all `tokio::process::Command` spawns set kill-on-drop; drift test asserting lag is surfaced not silently dropped.
+- Effort: ~6 tool calls / ~8 min.
+- Dependencies: none.
+- Risk: Low.
+
+**L4-F7 — No CI gate for async lifecycle.**
+- Gap: generated CI (`crates/forge_ci/src/workflows/ci.rs`, `.github/workflows/ci.yml`) runs coverage + the single zsh-rprompt perf job; no shutdown/leak test job.
+- Target: a CI job running shutdown/drain integration tests for forge3d + forge_dbd + FTS refresh, optionally under `tokio-console`/leak assertions.
+- Work items: add the integration tests above; wire a `lifecycle` job in `forge_ci` workflow source (CI is code-generated — edit the Rust, regenerate the yml).
+- Acceptance: CI fails if a server fails to drain within the timeout.
+- Effort: ~5 tool calls / ~8 min (after the tests in F1–F4 exist).
+- Dependencies: L4-F1..F4.
+- Risk: Low.

+
+## L6 — Performance Benchmarking Program (criterion, cargo bench, profiling, perf-regression gates)
+
+**What it measures:** Existence of a real, enforced perf program: micro-benchmarks for hot paths, `cargo bench` infra, profiling tooling, and CI regression gates with baselines.
+
+**Current state:** Essentially absent. Verified: zero `[[bench]]` sections, zero `criterion`/`divan`/`iai` deps, no `benches/` dirs anywhere (grep returned empty). The only perf signal in CI is one shell E2E gate: `crates/forge_ci/src/workflows/ci.rs#L22-31` → `.github/workflows/ci.yml` `zsh_rprompt_perf` job running `./scripts/benchmark.sh --threshold 60 zsh rprompt`. `scripts/benchmark.sh` just times the `forge` binary 10× and compares average wall-clock to a threshold — an E2E smoke gate, not a benchmark suite. `plans/2026-05-05-omniroute-benchmark-plan-v1.md` describes a criterion program but it targets a *different* project (OmniRoute) and is not implemented here.
+
+### Findings
+
+**L6-F1 — No microbenchmark suite for hot paths.**
+- Gap: no benches for the perf-critical crates: `forge_walker/src/walker.rs` (`get_blocking`, parallel walk under a global mutex, `#L125,L159,L196,L220`), `forge_json_repair` (regex/string-scan parser), `forge_similarity` (embedding + fallback), `forge_drift/src/detector.rs` (per-tier `observe`), `forge_stream`, `forge_fs`, `forge_eventsource_stream`.
+- Target: a `criterion` (or `divan`) bench per hot path with representative inputs (dir sizes/depths; JSON sizes incl. malformed; drift tiers T0–T3).
+- Work items: add `criterion` dev-dep at workspace level; create `benches/` + `[[bench]]` in each of the 7 crates; seed fixtures (use `forge_test_kit` if suitable).
+- Acceptance: `cargo bench -p forge_walker` (etc.) produces stable criterion reports; each bench < documented variance.
+- Effort: ~3 parallel subagents (one per crate cluster) / ~20 min.
+- Dependencies: none (but pairs with L8 — same hot paths).
+- Risk: Low.
+
+**L6-F2 — No `cargo bench` / profiling tooling.**
+- Gap: no `cargo bench` step in CI; no `flamegraph`/`pprof`/`divan`/`iai`. Mutex contention in `forge_walker` (`#L159,L196,L220`) and regex throughput in `forge_json_repair` are entirely unmeasured.
+- Target: profiling recipe (cargo-flamegraph or pprof feature) documented + at least an `iai`/`divan` instruction-count bench for one deterministic hot path (json_repair) for low-variance CI gating.
+- Work items: add a `make bench` / xtask target; add `iai-callgrind` or `divan` to json_repair; document a flamegraph recipe in the session docs.
+- Acceptance: deterministic instruction-count bench runs in CI without flakiness.
+- Effort: ~6 tool calls / ~10 min.
+- Dependencies: L6-F1.
+- Risk: Low.
+
+**L6-F3 — No perf-regression gate with baselines.**
+- Gap: `scripts/benchmark.sh` runs once per commit with a fixed 60ms threshold; no historical baseline, no per-crate p50/p95/p99 SLOs, no criterion baseline comparison.
+- Target: criterion `--save-baseline` in CI comparing PR vs main; fail on regression > X%.
+- Work items: add a `bench` CI job in `forge_ci` workflow source generating a yml job that runs criterion against a stored baseline (or `critcmp`); define per-crate regression thresholds.
+- Acceptance: CI fails when a seeded slowdown exceeds threshold; passes otherwise.
+- Effort: ~5 tool calls / ~8 min (after F1).
+- Dependencies: L6-F1, L6-F2.
+- Risk: Medium (CI flakiness on shared runners — mitigate with instruction-count benches from F2).
+

+
+## L7 — Concurrency Safety Verification (race/deadlock checking, sanitizers, shared-state discipline, cancellation correctness)
+
+**What it measures:** Whether shared mutable state is disciplined (no locks across await, no TOCTOU, clear lock ordering), whether `unsafe` is justified, and whether the project *verifies* concurrency (loom/shuttle/miri/ThreadSanitizer) rather than hoping.
+
+**Current state:** Concurrent code is everywhere; verification is zero. Confirmed absent: `loom`, `shuttle`, `miri`, `-Zsanitizer` (grep empty across all `*.toml`/`*.yml`). ~50 `unsafe` blocks across 11 files. Several risky shared-state shapes and lock-across-await sites.
+
+### Findings
+
+**L7-F1 — TOCTOU on `Arc<RwLock<Option<Arc<RmcpClient>>>>`.**
+- Gap: `crates/forge_infra/src/mcp_client.rs#L34` triple-wrapped client. `connect()` (`#L75-83`) does read-lock check → drop → long `create_connection().await` → separate write-lock set: two clients can be created under concurrent first-connect.
+- Target: atomic get-or-init (`tokio::sync::OnceCell` for the connection, or a single guarded init path), eliminating the check-then-set window.
+- Work items: replace the `RwLock<Option<…>>` with `OnceCell<Arc<RmcpClient>>` + an init future, or hold a dedicated init mutex across the create.
+- Acceptance: a loom or stress test spawning N concurrent `connect()` asserts exactly one `create_connection` runs.
+- Effort: ~6 tool calls / ~10 min.
+- Dependencies: coordinate with L4-F2 (stderr handle lives here).
+- Risk: Medium.
+
+**L7-F2 — Locks held across `.await` / across compute.**
+- Gap: `forge_tracker/src/dispatch.rs#L150-152` holds `email.lock().await` across `system_info().await`; `forge_services/src/template.rs#L108-112` holds the Handlebars `write().await` across the compile loop; `forge_infra/src/executor.rs#L101-141` holds a serialization `Mutex<()>` across the *entire* child-process execution (no timeout — a hung child blocks all `command()` callers). `forge_services/src/mcp/service.rs#L67` holds `tools.write().await` across `McpExecutor::new()`.
+- Target: compute/IO outside the critical section; lazy-init via double-check or `OnceCell`; replace the executor serialization `Mutex` with a `Semaphore(1)` (or a queue) so it is cancel/timeout-friendly.
+- Work items: hoist `system_info()` and template compilation out of the guard; convert executor `ready: Arc<Mutex<()>>` (`#L21`) to `Semaphore`; in MCP service build executors before taking the write lock, then insert.
+- Acceptance: lock-hold spans contain no `.await` on unrelated futures (verifiable by review + a clippy `await_holding_lock` allow-list audit); executor stress test shows callers are not blocked indefinitely by one hung command (with timeout).
+- Effort: ~10 tool calls / ~15 min.
+- Dependencies: none.
+- Risk: Medium (executor change alters serialization semantics — keep single-permit default).
+
+**L7-F3 — Thread-unsafe `std::env::set_var/remove_var` at runtime.**
+- Gap: `unsafe { std::env::set_var/remove_var }` in `forge_tracker/src/dispatch.rs#L288-316`, `forge_config/src/reader.rs#L189-201`, `forge_infra/src/env.rs#L180-187`. Edition-2024 made these `unsafe` precisely because they race with concurrent env reads.
+- Target: no runtime env mutation; route through an in-process overlay (`Arc<RwLock<HashMap<String,String>>>` or a config layer) read by the relevant code, or confine mutation to single-threaded startup before any tasks spawn.
+- Work items: introduce an env-overlay abstraction; replace runtime `set_var/remove_var`; restrict any remaining mutation to pre-runtime init with a `// SAFETY:` note.
+- Acceptance: zero `set_var/remove_var` outside `#[cfg(test)]`/pre-spawn init; documented for the rest.
+- Effort: ~8 tool calls / ~12 min.
+- Dependencies: none.
+- Risk: Medium (config-reading behavior could shift; needs test coverage).
+
+**L7-F4 — `unsafe` blocks lack SAFETY justifications.**
+- Gap: ~50 `unsafe` across 11 files; the 16 FFI blocks in `forge_main/src/zsh/plugin.rs` (e.g. `#L383,L391,L469,…`) have no `// SAFETY:` comments and pass pointers to C. (Some are genuinely fine, e.g. `forge_eventsource_stream/src/utf8_stream.rs#L64` `from_utf8_unchecked` after validation, `forge3d/src/pidfile.rs#L156` `libc::kill(pid,0)`.)
+- Target: every `unsafe` block carries a `// SAFETY:` invariant; deny-by-default via `#![warn(unsafe_op_in_unsafe_fn)]` + `clippy::undocumented_unsafe_blocks`.
+- Work items: add the clippy lint to CI; annotate each block; fix any that cannot be justified.
+- Acceptance: `clippy::undocumented_unsafe_blocks` passes clean in CI.
+- Effort: ~8 tool calls / 1 subagent / ~15 min.
+- Dependencies: none.
+- Risk: Low (annotation-only, plus possible real bug surfacing in zsh FFI).
+
+**L7-F5 — No race/UB verification in CI.**
+- Gap: CI (`.github/workflows/ci.yml`, `forge_ci` source) has coverage only — no miri, no loom/shuttle, no ThreadSanitizer.
+- Target: (a) `cargo +nightly miri test` on the pure/logic crates (`forge_json_repair`, `forge_domain`, `forge_eventsource_stream`); (b) loom tests for the two highest-risk state machines (MCP client init L7-F1, MCP service lock ordering `forge_services/src/mcp/service.rs#L27-30,L103-176`); (c) optional TSan job.
+- Work items: add loom dev-dep behind a `loom` feature with model tests for the two paths; add miri + (optional) TSan jobs to `forge_ci` workflow source.
+- Acceptance: miri job green on selected crates; loom models pass; jobs run on Linux runners (per billing policy — Linux only).
+- Effort: ~10 tool calls / 1 subagent / ~18 min.
+- Dependencies: L7-F1 (loom model targets it).
+- Risk: Medium (miri may reject FFI/process crates — scope to pure crates).

+
+## L8 — Memory Management & Efficiency (allocator, heap profiling, budgets, zero-copy, allocation discipline)
+
+**What it measures:** Allocator choice for a high-throughput long-running agent, heap-profiling instrumentation, CI memory budgets, and allocation discipline (zero-copy, bounded buffers, capacity hints) in hot paths.
+
+**Current state:** Weakest pillar (0.5). Confirmed: no `#[global_allocator]`, no `jemalloc`/`mimalloc` (grep empty) → default system allocator; no `dhat`/`bytehound`/`heaptrack`; no CI memory gate. `bytes::Bytes`/`Cow` are used in a few good spots (`forge_domain/src/provider.rs`, `catalog.rs`) but streaming and FS paths are `String`/`Vec`-heavy.
+
+### Findings
+
+**L8-F1 — Default system allocator (no jemalloc/mimalloc).**
+- Gap: no `#[global_allocator]` anywhere; verified. For a long-running, multi-threaded (tokio multi-thread + dashmap) agent with bursty small allocations, the system allocator fragments and adds latency variance.
+- Target: `#[global_allocator]` = jemalloc (`tikv-jemallocator`) or mimalloc in the binary crate(s) (`forge_main`, `forge3d`, `forge_dbd`), feature-gated for benchmarking comparison.
+- Work items: add `tikv-jemallocator` dep; declare global allocator in `forge_main/src/main.rs` (and the other bins); gate behind a feature so A/B measurable.
+- Acceptance: before/after measurement (peak RSS + p99 of the zsh-rprompt gate / a new bench) showing no regression and ideally improvement; allocator selectable via feature.
+- Effort: ~4 tool calls / ~6 min.
+- Dependencies: pairs with L6 (need a bench to measure the win).
+- Risk: Low (well-trodden; jemalloc on musl needs a check if static builds are used).
+
+**L8-F2 — No heap profiling instrumentation.**
+- Gap: no `dhat` (or equiv); allocation trends/regressions cannot be tracked.
+- Target: `dhat-rs` behind a `dhat-heap` feature; profiled runs of the hot paths.
+- Work items: add `dhat` dev/optional dep; add `#[dhat::dhat]` harness to representative tests/benches (walker, json_repair, eventsource stream).
+- Acceptance: `cargo run --features dhat-heap` emits a dhat profile; documented baselines for the 3 paths.
+- Effort: ~6 tool calls / ~10 min.
+- Dependencies: none.
+- Risk: Low.
+
+**L8-F3 — Unbounded / per-chunk allocations in streaming hot paths.**
+- Gap: `forge_eventsource_stream/src/event_stream.rs#L137-140` (`buffer: String` + `last_event_id: String`, no capacity), `#L272`/`split_off` reallocates remainder per event; `EventBuilder` `event.data.push_str` grows unbounded with no cap (`#L45-55`). `utf8_stream.rs#L24-26,L55-75` accumulates `Vec<u8>` then allocates a fresh `String` per poll instead of zero-copy `Bytes`.
+- Target: `bytes::Bytes`/`BytesMut` for byte buffers; capacity hints; a max-event-size cap with a clear error (no silent unbounded growth).
+- Work items: convert eventsource buffers to `BytesMut`; emit `Bytes` slices; add `with_capacity`; enforce a configurable max event size.
+- Acceptance: dhat (L8-F2) shows reduced alloc count/bytes on a streaming bench; oversized-event test returns an error rather than growing.
+- Effort: ~10 tool calls / 1 subagent / ~18 min.
+- Dependencies: L8-F2 (to prove the win).
+- Risk: Medium (streaming correctness — needs SSE conformance tests).
+
+**L8-F4 — FS/walker allocation pressure (eager Vec, clone-heavy).**
+- Gap: `forge_infra/src/fs_read.rs#L33-36` clones every chunk into `Vec<Vec<PathBuf>>`; `forge_walker/src/walker.rs#L120-122,L243-266` accumulates `Arc<Mutex<Vec<File>>>` with `to_string_lossy().to_string()` per entry, unbounded `HashMap<String,usize>`; `forge_services/src/tool_services/fs_read.rs#L171-201` builds `Vec<&str>` then per-range `Vec<_>` + `join` (no `with_capacity`); `forge_markdown_stream/src/table.rs#L232,256,266,282` `active_style.clone().unwrap_or_default()` in the render loop.
+- Target: stream walker results (async iterator) instead of materializing `Vec<File>`; lazy chunking; `Cow<str>`/borrows for styles; `String::with_capacity` for joins.
+- Work items: change `Walker::get*` to yield a stream; make fs_read batching lazy; pass styles by `&`/`Cow`; pre-size join buffers.
+- Acceptance: dhat shows lower peak on a large-tree walk + large-file read bench; behavior unchanged (existing walker/fs tests green).
+- Effort: ~12 tool calls / 1 subagent / ~20 min.
+- Dependencies: L6-F1 + L8-F2 (benches to gate).
+- Risk: Medium (walker API change ripples to callers).
+
+**L8-F5 — No CI memory budget gate.**
+- Gap: CI has no peak-RSS / allocation-count budget; regressions invisible.
+- Target: a CI job asserting peak RSS (or dhat alloc bytes) on a fixed workload stays under a budget.
+- Work items: add a `memory-budget` job to `forge_ci` workflow source running the dhat-instrumented bench and failing on budget breach (Linux runner per billing policy).
+- Acceptance: seeded allocation regression fails CI; baseline passes.
+- Effort: ~5 tool calls / ~8 min (after L8-F2).
+- Dependencies: L8-F2.
+- Risk: Medium (runner variance — prefer dhat alloc-count, which is deterministic, over RSS).
+
+---
+
+## Top 3 Highest-Leverage Overhauls
+
+1. **Stand up a real benchmark + profiling spine (L6-F1/F2 + L8-F2), then flip the allocator (L8-F1).** This is the keystone: it is the prerequisite that turns every other perf/memory change from "trust me" into "measured." Adding criterion/divan benches to the 7 hot crates plus dhat instrumentation, then dropping in jemalloc behind a feature, directly lifts L6 (1.0) and L8 (0.5) and de-risks all L4/L7/L8 refactors. ~3 parallel subagents / ~30 min.
+
+2. **Introduce a uniform task-lifecycle convention and apply it to the long-lived servers + fire-and-forget spawns (L4-F1, F3, F4, F5).** A shared `CancellationToken` + `JoinSet`/Drop pattern (already modeled correctly in `title_generation.rs` and `mpsc_stream.rs`) applied to FTS refresh, forge3d accept, forge_dbd, and the telemetry/debug spawns eliminates task leaks and the forge_dbd data-loss-on-exit bug, and unblocks a CI lifecycle gate. Highest correctness payoff. ~1 subagent + parent / ~35 min.
+
+3. **Close the concurrency-verification gap on the two riskiest state machines + kill runtime env mutation (L7-F1, F2, F3, F5).** Fix the MCP client TOCTOU and the lock-across-await/executor-serialization hazards, remove thread-unsafe `set_var`/`remove_var`, and prove it with loom models + a miri CI job on the pure crates. This converts L7's "concurrent but unverified" (1.0) into verified, and removes the most likely sources of intermittent prod hangs. ~1 subagent / ~30 min.

+# W03 Overhaul Findings — forgecode (L5 Observability, L26 Resilience, L27 Failure-Observability)
+
+> Cluster mean (v37 scorecard): **0.83** — weakest cluster for forgecode.
+> Audit target: canonical `main` @ `536bb23b8` (34-crate Rust workspace).
+> Method: read of current source + workspace-wide pattern sweeps. Evidence-based, no fabrication.
+
+## Framing note (load-bearing for all three pillars)
+
+forgecode is primarily a **CLI/TUI binary** (`crates/forge_main/src/main.rs`), not a long-lived HTTP service.
+There is exactly one long-running server component: `forge_dbd`, a **Unix-socket SQLite daemon**
+(`crates/forge_dbd/src/server.rs:47` binds a `UnixListener`, accept loop at `:56`).
+
+This matters: the v37 scorecard penalized for missing `prometheus`, `health_checks`, `slo`, `metrics` (`audit_scorecard.json:359-364`).
+For a CLI those are partly category-mismatched — a prometheus endpoint on a one-shot CLI is meaningless. The *real* gap is
+that the pieces that DO apply (structured run telemetry, in-process metrics emission, daemon health/SLO, incident/runbook
+artifacts) are absent or fragmented. Targets below are calibrated to "good observability/resilience **for a CLI + local daemon**,"
+which is the honest bar — not a microservice SLO stack bolted onto a terminal app.
+
+---
+
+## L5 — Observability (current: △ 1.5/3)
+
+### What it measures
+End-to-end observability: structured logging **plus** metrics, tracing spans, health checks, and SLO surface — not just log lines.
+Scorecard credited JSON logging + lifecycle hooks but flagged `prometheus:0, health_checks:0, tracing:0, metrics:0, slo:0`.
+
+### Current state (verified)
+- JSON `tracing_subscriber` with `EnvFilter`, non-blocking writer, PostHog-vs-rolling-file split: `crates/forge_tracker/src/log.rs:11-61`.
+- Lifecycle event logs (start/request/response/toolcall/end): `crates/forge_app/src/hooks/tracing.rs:8-247`. Note these are **`debug!`/`info!` log statements, not `tracing` spans** — request handlers at `:46-56` are intentionally no-ops.
+- The `metrics::` hits found across `forge_app` (e.g. `init_conversation_metrics.rs`) are **domain metrics** (token/cost/conversation counters), not an observability metrics pipeline. There is no `metrics`/`opentelemetry`/`prometheus` crate in any `Cargo.toml`.
+- No spans: logging is flat events; no `#[instrument]` / `span!` to correlate a tool call to its parent request/conversation.
+
+### Findings
+
+**L5-F1 — No span instrumentation; events are uncorrelated.**
+- **Gap**: `crates/forge_app/src/hooks/tracing.rs:46-56` discards request-level structure; nothing ties a `ToolcallStart`→`ToolcallEnd`→`Response` to a single span. Debugging a slow/failed run means grepping flat JSON with no parent/child linkage.
+- **Target state (2.5+)**: every orchestration request and tool call wrapped in a `tracing::span` carrying `conversation_id`, `agent_id`, `model_id`, `tool_name`; durations recorded on span close.
+- **Work items**: in `forge_app/src/hooks/tracing.rs` and the orchestrator (`forge_app/src/orch.rs`), replace flat `info!`/`debug!` with `#[instrument]`-style spans or manual `span!` enter/exit; emit `elapsed_ms` on `ToolcallEnd`/`Response`. Add a `forge_id`/`correlation_id` field propagated from `Conversation`.
+- **Acceptance**: a single failed tool call's JSON log lines all share one `span.id`; a span-close line carries `elapsed_ms`. Snapshot test in `forge_app` asserting span fields present.
+- **Effort**: 6-10 tool calls / 1 subagent / ~3-5 min.
+- **Dependencies**: none.
+- **Risk**: low — additive over existing tracing; no behavior change.
+
+**L5-F2 — No metrics emission layer (`metrics` facade absent).**
+- **Gap**: token/cost/latency exist only as ad-hoc domain counters logged as text; there is no queryable metrics surface. No `metrics` crate dep anywhere (`grep` of all `Cargo.toml` returns only `backon`).
+- **Target state (2.5+)**: a thin metrics facade (the `metrics` crate) emitting counters/histograms for tool-call count, tool-call duration, retry attempts, request latency, error count by kind. For the CLI, a `--metrics-dump` end-of-run summary (or JSON sidecar) is the honest exporter; for `forge_dbd`, an optional `metrics-exporter-prometheus` text recorder behind a feature flag.
+- **Work items**: add `metrics = "0.24"` (workspace dep); create `crates/forge_tracker/src/metrics.rs` registering counters/histograms; instrument retry (`forge_app/src/retry.rs`), tool registry (`forge_app/src/tool_registry.rs`), HTTP (`forge_infra/src/http.rs`). Add `metrics-util` debugging recorder for CLI end-of-run dump; gate a prometheus recorder for `forge_dbd` under a `metrics-server` cargo feature.
+- **Acceptance**: `forge … --metrics-dump` prints non-zero `tool_call_duration` histogram + `retry_attempts_total`; unit test increments a counter and reads it back via the debug recorder.
+- **Effort**: 10-15 tool calls / 2 parallel subagents / ~5-8 min.
+- **Dependencies**: L5-F1 (spans give natural histogram boundaries) recommended but not required.
+- **Risk**: medium — new workspace dep, touches hot paths; mitigate with no-op recorder default (zero overhead when unset).
+
+**L5-F3 — `forge_dbd` daemon has no health/readiness probe.**
+- **Gap**: `crates/forge_dbd/src/server.rs:47-56` accepts connections but exposes no health command; a client cannot ask "is the SQLite daemon healthy / has it finished migrations." `grep` for `health|readiness|liveness` across `crates/*/src` returns only `forge3d/src/main.rs` (unrelated GPU demo).
+- **Target state (2.5+)**: daemon answers a `Ping`/`Health` request returning `{status, db_open, schema_version, uptime}`.
+- **Work items**: add a `Health` variant to the daemon's request protocol in `forge_dbd`; handler runs `SELECT 1` against the pool and reports schema version; client helper `health()` in the daemon client module.
+- **Acceptance**: integration test starts daemon, sends `Health`, asserts `status==ok` and a schema version; after closing the DB, asserts degraded status.
+- **Effort**: 5-8 tool calls / 1 subagent / ~3-5 min.
+- **Dependencies**: none.
+- **Risk**: low — additive protocol variant, scoped to one crate.
+
+---
+
+## L26 — Resilience (current: △ 1.7/3)
+
+### What it measures
+Full resilience stack: retry/backoff **and** circuit breaking, bulkheads/concurrency limits, timeouts, and graceful degradation — applied consistently, not per-callsite.
+
+### Current state (verified)
+- Centralized retry helper with exponential backoff + jitter + `Error::Retryable` gating: `crates/forge_app/src/retry.rs:7-39`. Callers: `git_app.rs:216`, `orch.rs:302`, and a provider test (`openai_responses/repository.rs:1763`).
+- **Inconsistency**: at least three *separate* backoff implementations exist instead of one. `forge_infra/src/mcp_client.rs:498` hand-rolls `ExponentialBuilder` with a hard-coded `with_max_times(5)` (ignores `RetryConfig`); `forge_repo/src/database/pool.rs:73,92,171` has its own `retry_with_backoff` (blocking variant). The shared `retry.rs` is bypassed by both.
+- HTTP timeouts (connect/read/pool-idle/keep-alive) configured: `crates/forge_infra/src/http.rs:41-69`.
+- Panic safety: global panic hook installed in `crates/forge_main/src/main.rs:91`.
+- **Missing entirely**: circuit breaker (0 hits), bulkhead/concurrency cap (0 hits for `bulkhead`/`semaphore.*limit`).
+
+### Findings
+
+**L26-F1 — Three divergent retry implementations; `RetryConfig` not honored everywhere.**
+- **Gap**: `forge_infra/src/mcp_client.rs:498` and `forge_repo/src/database/pool.rs:85-92` reimplement backoff and ignore the user-configurable `RetryConfig` consumed by `forge_app/src/retry.rs`. A user raising `max_attempts` does not affect MCP transport retries.
+- **Target state (2.5+)**: a single retry primitive (in `forge_app` or a new `forge_resilience` module) parameterized by `RetryConfig` + a per-callsite `should_retry` predicate; MCP and pool both route through it (async + blocking flavors of one builder).
+- **Work items**: extend `retry.rs` with a `retry_blocking_with_config` sibling and a pluggable predicate; refactor `mcp_client.rs:496-520` to call it with a transport-error predicate (preserving the client-take-on-transport-failure side effect); refactor `pool.rs` retries to the blocking variant. Delete the duplicated builders.
+- **Acceptance**: `grep ExponentialBuilder crates` returns only the shared module; test sets `max_attempts` via `RetryConfig` and observes that many MCP/pool attempts.
+- **Effort**: 8-12 tool calls / 2 subagents / ~5-8 min.
+- **Dependencies**: none.
+- **Risk**: medium — touches MCP transport recovery and DB pool acquisition (both fault paths); needs the existing side-effects (drop transport client on failure) preserved.
+
+**L26-F2 — No circuit breaker on provider/MCP calls.**
+- **Gap**: retries are unbounded-per-attempt with no breaker; a persistently-down provider gets hammered every request with full backoff cost. No circuit-breaker pattern anywhere (0 hits).
+- **Target state (2.5+)**: a per-endpoint breaker (closed→open→half-open) wrapping provider HTTP and MCP transport; trips after N consecutive failures, fast-fails for a cool-down, probes on half-open. (Note: this dovetails with the active branch `fix/5109-proxy-fast-fail-concurrency` — proxy fast-fail is the same concern.)
+- **Work items**: add a breaker to a `forge_resilience` module (wrap `failsafe` crate or hand-roll a small `AtomicState` breaker — prefer wrapping `failsafe = "1"`); key by provider base-URL / MCP server id; wrap call sites in `forge_repo/src/provider/*` and `forge_infra/src/mcp_client.rs`. Surface breaker state in logs/metrics (ties to L5-F2).
+- **Acceptance**: test simulates N failing calls, asserts subsequent call fast-fails (`CircuitOpen`) without hitting the network, then recovers after cool-down.
+- **Effort**: 12-18 tool calls / 2-3 parallel subagents / ~8-12 min.
+- **Dependencies**: L26-F1 (unify retry first so breaker wraps one path); coordinate with `fix/5109` branch to avoid duplicate fast-fail logic.
+- **Risk**: high blast-radius — sits on the critical request path for every LLM call; a mis-tuned breaker can block valid traffic. Ship behind config with conservative defaults + feature gate.
+
+**L26-F3 — No concurrency cap / bulkhead on tool & provider fan-out.**
+- **Gap**: no `Semaphore`-based limit isolating tool execution or concurrent provider requests (0 hits). A burst of parallel tool calls can exhaust the HTTP pool (`pool_max_idle_per_host: 5`, `http.rs:46`) or fds.
+- **Target state (2.5+)**: a bounded `tokio::sync::Semaphore` bulkhead around concurrent tool execution and provider calls, sized from config; excess work queues rather than over-subscribing.
+- **Work items**: add a configurable semaphore in the orchestrator (`forge_app/src/orch.rs`) / tool registry (`forge_app/src/tool_registry.rs`); add `max_concurrent_tools` / `max_concurrent_requests` to `forge_config`. Emit a saturation metric (L5-F2).
+- **Acceptance**: test launches more concurrent tool calls than the cap, asserts in-flight count never exceeds the limit.
+- **Effort**: 6-10 tool calls / 1-2 subagents / ~5 min.
+- **Dependencies**: L5-F2 for the saturation metric (optional).
+- **Risk**: medium — a too-low cap serializes legitimate parallelism; default to a generous value.

+
+## L27 — Failure-Observability / Incident Readiness (current: ✗ 0.3/3 — weakest pillar in the cluster)
+
+### What it measures
+Operational failure artifacts: SLOs/SLIs, burn-rate alerts, runbooks, postmortem templates, incident response docs — the "what do we do when it breaks" surface.
+
+### Current state (verified)
+- **Effectively none.** `find` for `*slo*|*runbook*|*postmortem*|*incident*` across the repo returns zero files. `docs/operations/` contains only `iconography/` and `journey-traceability.md` — no runbook, no SLO, no incident template.
+- The only incident-adjacent text is an incidental mention inside a skill markdown (`forge_repo/src/skills/github-pr-description/SKILL.md`), not an operational artifact.
+
+### Findings
+
+**L27-F1 — No SLO/SLI definitions.**
+- **Gap**: nothing defines what "healthy" means quantitatively (e.g. `forge_dbd` availability, request success rate, p95 tool-call latency). Without SLIs, the L5-F2 metrics have no targets.
+- **Target state (2.5+)**: `docs/operations/SLO.md` defining 3-5 SLIs with targets and measurement source, mapped to the metrics from L5-F2.
+- **Work items**: author `docs/operations/SLO.md`: daemon availability target, LLM-request success-rate SLI, tool-call p95 latency objective, retry-exhaustion budget; each row cites the emitting metric name.
+- **Acceptance**: doc exists; every SLI references a real metric name introduced in L5-F2 (cross-checkable).
+- **Effort**: 2-4 tool calls / planning-only / ~2 min (doc).
+- **Dependencies**: best authored alongside L5-F2 so metric names exist.
+- **Risk**: none (doc only).
+
+**L27-F2 — No runbooks for the known failure modes.**
+- **Gap**: the codebase already encodes specific failure modes (MCP transport drop `mcp_client.rs:498`, DB pool acquisition failure `pool.rs:73`, provider retry exhaustion `retry.rs`, panic hook `main.rs:91`) but there is zero operator/dev guidance on diagnosing or recovering them.
+- **Target state (2.5+)**: `docs/operations/runbooks/` with one runbook per failure class: MCP server won't connect, SQLite daemon down/locked, provider 429/5xx storm, panic crash triage (where logs land per `log.rs:54` rolling file).
+- **Work items**: create `docs/operations/runbooks/{mcp.md,sqlite-daemon.md,provider-errors.md,crash-triage.md}`; each: symptom → log signature (cite the actual `tracing` message) → diagnosis → recovery → escalation.
+- **Acceptance**: 4 runbooks exist; each cites a real log message string present in source.
+- **Effort**: 4-6 tool calls / 1 subagent / ~3-5 min (docs).
+- **Dependencies**: L5-F1 (span/log fields) makes log signatures stable to cite.
+- **Risk**: none (doc only); risk is staleness — mitigate by citing exact source strings.
+
+**L27-F3 — No postmortem/incident template + no burn-rate alerting hook.**
+- **Gap**: no incident template, no error-budget burn tracking. Combined with `forge_dbd` having no health probe (L5-F3), there is no way to know an incident is occurring.
+- **Target state (2.5+)**: `docs/operations/POSTMORTEM_TEMPLATE.md` (blameless format) + an `docs/operations/alerting.md` describing burn-rate alert thresholds against the SLOs, wired to the prometheus exporter feature from L5-F2 for `forge_dbd` deployments.
+- **Work items**: author postmortem template + alerting doc; define multi-window burn-rate rules referencing L27-F1 SLOs; reference the L5-F2 prometheus feature for the daemon scrape target.
+- **Acceptance**: template + alerting doc exist; alert thresholds reference SLIs from L27-F1.
+- **Effort**: 2-4 tool calls / planning-only / ~2 min (docs).
+- **Dependencies**: L27-F1 (SLOs), L5-F2 (metrics), L5-F3 (daemon health).
+- **Risk**: none (doc only).

+
+## Top 3 highest-leverage overhauls for this cluster
+
+1. **Unify retry + add circuit breaker (L26-F1 → L26-F2).** Highest single-pillar lift: collapses 3 divergent backoff implementations into one config-honoring primitive, then adds breaker fast-fail on top. Directly raises L26 toward 2.5 and aligns with the in-flight `fix/5109-proxy-fast-fail-concurrency` branch — do this first to avoid duplicate fast-fail logic. ~13-30 tool calls / 2-3 subagents.
+
+2. **Metrics facade + spans (L5-F2 + L5-F1).** Adds the queryable observability surface the scorecard explicitly docked (`metrics:0`, `tracing:0` as *spans*), and is the prerequisite that makes the entire L27 doc set real (SLOs/alerts need metric names to reference). Default no-op recorder = zero risk to the CLI hot path. ~16-25 tool calls / 2 subagents.
+
+3. **Operations doc set: SLO + runbooks + postmortem/alerting + daemon health probe (L27-F1/F2/F3 + L5-F3).** Moves the cluster's weakest pillar (L27 at 0.3) the furthest for the least risk — almost entirely additive docs plus one small `forge_dbd` health variant. Author last so SLIs/runbooks cite the real metrics and log strings produced by overhauls #1 and #2. ~13-22 tool calls / 1-2 subagents.

+# W05 Deep Audit — forgecode (L11 Testing-DX · L12 Docs/SSOT · L13 Onboarding-DX)
+
+- Repo: `~/CodeProjects/Phenotype/repos/forgecode` (canonical `main`)
+- Nature: 34-crate Rust workspace, ~144,554 LOC of `.rs` (fork of `tailcallhq/forgecode`), plus a small vestigial TypeScript "evals" subsystem under `src/` and `benchmarks/`.
+- Prior cluster mean: **1.4/3** (L11 1.4, L12 1.2, L13 1.6).
+- Audit date: 2026-06-28. PLANNING audit — no source modified.
+
+> ⚠️ **Scorecard provenance warning.** The prior `W05.md` scorecard audited a *stale snapshot* that looked like a pure Node/TS repo (`tests/domain.test.ts`, `just test` → Node test runner, "no `.devcontainer/`", "no `CONTRIBUTING.md`"). The CURRENT canonical repo is the opposite: a large Rust workspace that *does* have `.devcontainer/`, `CONTRIBUTING.md`, `CODEOWNERS`, `SECURITY.md`, and `.config/nextest.toml`. Several of the scorecard's gaps are therefore obsolete — but the underlying scores still hold (often for *different, worse* reasons), as detailed below. All citations here are against the live tree.

+
+## L11 — Testing, Coverage Gating & DX
+
+### What it measures
+Presence and *enforcement* of an automated test/quality safety net: a gating test job, a coverage threshold that fails CI, lint/format gates, and SOTA test categories (property-based, mutation, fuzz, snapshot). Informational-only checks score low.
+
+### Current state (evidence)
+- **Real test mass exists**: 277 files contain `#[test]`/`#[tokio::test]`, 170 `.snap` insta snapshots, 0 pending `.snap.new`. `.config/nextest.toml#1-12` configures a nextest default profile (1s slow-timeout, fail-only status). AGENTS.md (`AGENTS.md#13-46`) documents a disciplined fixture/`actual`/`expected` + `pretty_assertions` test convention. This is a genuine, healthy local test culture.
+- **GAP 1 — no gating test job in CI.** `.github/workflows/ci.yml` has exactly two PR jobs: `build` (`ci.yml#37-56`) and `zsh_rprompt_perf` (`ci.yml#57-74`). The `build` job's only real step is `cargo llvm-cov --all-features --workspace --lcov --output-path lcov.info` (`ci.yml#56`). There is **no `cargo nextest run` / `cargo test` step** whose name/exit semantics make a *test failure* a first-class CI failure. Tests run only as a side-effect of coverage generation.
+- **GAP 2 — coverage is generated then discarded.** `lcov.info` is produced (`ci.yml#56`) but **never uploaded** (no Codecov/artifact step) and there is **no `--fail-under-lines` / threshold gate**. Coverage is purely informational — exactly the "informational not gated" pattern the rubric penalizes.
+- **GAP 3 — lint/format/string-safety gates only run in an auto-fixer, not as a gate.** All of `cargo +nightly fmt --all`, `cargo +nightly clippy ... --fix --allow-dirty -- -D warnings`, and the string-safety clippy pass (`-D clippy::string_slice -D clippy::indexing_slicing -D clippy::disallowed_methods`) live in `.github/workflows/autofix.yml#52-57`. That workflow *mutates and commits* fixes (`--fix --allow-dirty` + `autofix-ci/action`); it does not block a PR on residual unfixable lint/format violations. `RUSTFLAGS: -Dwarnings` is set (`autofix.yml#20`, `ci.yml#20`) but the compile that enforces it is the coverage build, not a named gate.
+- **GAP 4 — no SOTA test categories.** `rg proptest` over `crates/**/*.rs` → **0** hits. No mutation testing (`cargo-mutants` absent from CI/configs), no fuzz targets (no `fuzz/` dir). Insta snapshots are the only SOTA category present (32 files use `insta::`).
+- **GAP 5 — large untested crates.** Per-crate `#[test]` file counts show structural holes: `forge_api` (939 LOC) = **0** test files; `forge_tui` = 0; `forge_eventsource` = 0; `forge_embed` = 0; `forge_dbd` = 0; `forge_ci` = 0; `forge_tool_macros` = 0; `ghostty-kit` = 0. Coverage being ungated means these holes are invisible in CI.
+
+### Overhaul findings
+
+| # | Gap | Target state | Work items (crates/files) | Acceptance criteria | Effort | Deps | Risk |
+|---|-----|--------------|---------------------------|---------------------|--------|------|------|
+| L11-1 | No gating test job | Dedicated required `test` job that fails on any test failure | Add `cargo nextest run --all-features --workspace --profile ci` job to `.github/workflows/ci.yml` (note: file is **gh-workflow-gen generated** — `ci.yml#5-12` — so edit the `build.rs`/gh-workflow source, not the YAML). Add `[profile.ci]` to `.config/nextest.toml`. | A PR with a failing `#[test]` is blocked by a red required check named `test`. | 3-6 tool calls | Must edit workflow generator, not raw YAML | Low |
+| L11-2 | Coverage ungated + discarded | Coverage uploaded as artifact + ratchet threshold | In coverage step add `--fail-under-lines <baseline>` (start at measured floor, e.g. 50%) and upload `lcov.info` via `actions/upload-artifact` or Codecov. | CI fails if line coverage drops below baseline; lcov.info downloadable per run. | 3-5 tool calls | L11-1 (share build) | Low–Med (baseline must be measured first to avoid instant red) |
+| L11-3 | Lint/fmt only auto-fixed, never gated | Separate non-mutating `lint` gate | Add a *check-only* job: `cargo +nightly fmt --all --check` + `cargo +nightly clippy --all-features --workspace --all-targets -- -D warnings` (no `--fix`). Keep `autofix.yml` for convenience but make the check-only job required. | PR with unfixable clippy/fmt violation is blocked. | 3-5 tool calls | Generator edit (as L11-1) | Low |
+| L11-4 | No property/mutation/fuzz | Introduce ≥1 SOTA category on a pure-logic crate | Add `proptest` dev-dep + property tests to `crates/forge_json_repair` and `crates/forge_similarity` (deterministic, pure). Optionally `cargo-mutants` nightly cron on `forge_domain`. | ≥1 proptest suite green in CI; mutants report artifact (if added). | 8-15 tool calls (2 parallel subagents) | L11-1 for execution | Med (proptest flakiness; cap cases) |
+| L11-5 | Untested high-value crates | Smoke/unit coverage for `forge_api`, `forge_eventsource`, `forge_embed` | Add `#[tokio::test]` suites per AGENTS.md convention; target ≥1 test/public-fn for `forge_api` (939 LOC, 0 tests). | Each named crate has ≥1 passing test file; coverage baseline (L11-2) rises. | 15-30 tool calls (3-5 parallel subagents) | L11-1, L11-2 | Med |

+
+## L12 — Documentation & SSOT
+
+### What it measures
+Single Source of Truth discipline: accurate root README, a canonical docs index/precedence map, governance docs, and **docs that actually describe the real system**. Drift/contradiction is the heaviest penalty.
+
+### Current state (evidence) — this is the cluster's worst pillar, and worse than scored
+- **GAP 1 — README describes the WRONG project.** `README.md#1-3` titles the repo "**ForgeCode Evals — TypeScript evaluation and bounty-cli tooling**" and `README.md#13-23` documents a `src/domain | ports | adapters | app` hexagonal *TypeScript* layout. The actual product is a 34-crate Rust CLI (`Cargo.toml#1-34`). `README.md#25-44` Quick Start is entirely `npm install` / Node. A new reader is told the wrong language, wrong architecture, wrong build.
+- **GAP 2 — SSOT is stale and self-contradicting.** `docs/SSOT.md#1-13` says "ForgeCode Evals", "Last verified: 2026-06-08", and under Dependencies lists **`Rust: N/A`, `Node: 20`** — for a repo with 144k LOC of Rust across 34 crates. `docs/SSOT.md#16-21` claims the architecture is `ProviderPort/StoragePort/NotifierPort` + `GithubApiAdapter/CsvAdapter` — none of which exist in `crates/`. The SSOT, the document whose entire job is to be authoritative, is describing a different codebase.
+- **GAP 3 — Bifurcated/contradictory governance docs.** `AGENTS.md#1-46` correctly describes the Rust project (anyhow/thiserror, fixtures, pretty_assertions). But `CONTRIBUTING.md#1-25` is a generic stub that hedges ("Run `cargo fmt` for Rust projects, *or the appropriate linter for your stack*" — `CONTRIBUTING.md#14`), and `README.md`/`SSOT.md` describe TS. There is **no canonical docs index or precedence table** reconciling them (`docs/index.md` exists but was not surfaced as a precedence map).
+- **GAP 4 — vestigial subsystem masquerading as the whole.** A real but tiny TS evals subsystem does exist (`src/index.ts`, `src/domain|ports|adapters|app`, `package.json` name `forge-code-evals`, `benchmarks/cli.ts`). The docs elevate this side-tool to be *the project*, hiding the Rust CLI entirely. SSOT "Next Steps" (`docs/SSOT.md#22-28`) plans `zod` schema validation for evals — i.e. the SSOT roadmap is for the side-tool.
+- Partial credit exists: `docs/adr/0001-compaction-summarization-strategy.md`, `docs/intent/forgecode.md`, `docs/boundary/forgecode.md`, `docs/operations/journey-traceability.md`, `docs/tool-guidelines.md`, `docs/slsa.md` are real and Rust-relevant — but they orbit a README/SSOT that point elsewhere.
+
+### Overhaul findings
+
+| # | Gap | Target state | Work items (files) | Acceptance criteria | Effort | Deps | Risk |
+|---|-----|--------------|--------------------|---------------------|--------|------|------|
+| L12-1 | README describes wrong project | README documents the Rust CLI as the primary product; TS evals demoted to a clearly-scoped subsection | Rewrite `README.md`: title/stack/quick-start for the Rust workspace (`cargo build`, `cargo nextest run`); move TS-evals to a `## Evals (TS subtool)` section pointing at `src/`+`benchmarks/`. | README's stack/build/arch match `Cargo.toml` + `crates/`; no Node-only quick start at top. | 3-6 tool calls | Decide product framing (Rust-primary) | Low |
+| L12-2 | SSOT stale & wrong | `docs/SSOT.md` is the accurate authoritative map | Rewrite `docs/SSOT.md`: Dependencies `Rust: <toolchain>`/Node-for-evals; Architecture = real crate map (api/app/domain/services/infra/tui/...); refresh "Last verified"; DAG reflects Rust roadmap. | SSOT crate list matches `Cargo.toml#1-34`; `Rust: N/A` removed; reviewer can navigate repo from SSOT alone. | 3-6 tool calls | L12-1 (consistent framing) | Low |
+| L12-3 | No docs precedence/index | Canonical `docs/index.md` precedence table | Make `docs/index.md` a precedence map: SSOT > ADRs > AGENTS > CONTRIBUTING > README, with one-line purpose + link each. | Index lists every root/doc governance file with role; no contradictions between linked docs. | 2-4 tool calls | L12-1, L12-2 | Low |
+| L12-4 | CONTRIBUTING stub | Rust-specific contributor workflow | Rewrite `CONTRIBUTING.md`: concrete `cargo nextest`/`cargo +nightly fmt`/clippy commands, fixture convention link to AGENTS.md, PR/label flow. | No "or the appropriate linter for your stack" hedging; commands runnable verbatim. | 2-3 tool calls | — | Low |
+| L12-5 | Vestigial subsystem ambiguity | Explicit boundary doc for the two subsystems | Add `## Subsystems` to SSOT/boundary doc: (a) Rust CLI = product, (b) TS evals = internal benchmarking; state ownership + lifecycle of each. | A reader can tell which dir belongs to which subsystem in <1 min. | 2-3 tool calls | L12-2 | Low |
+
+---
+
+## L13 — Onboarding & Contributor DX
+
+### What it measures
+One-command setup, an accurate task runner, working devcontainer, and a quick-start that gets a contributor to a green build fast.
+
+### Current state (evidence)
+- **Strong bones, wrong stack wiring.** `.devcontainer/devcontainer.json` exists and is genuinely good (`.devcontainer/devcontainer.json#1-38`): Rust base image, `postCreateCommand` installs `cargo-insta`, `cargo-nextest`, `ast-grep`, clippy/rustfmt, fzf/fd — i.e. it *is* set up for the Rust workflow. This directly contradicts the prior scorecard's "no `.devcontainer/`".
+- **GAP 1 — Justfile is 100% the wrong stack.** `Justfile#9-33` defines `install: npm install`, `test: npm run test:bounty`, `lint: npx eslint . --ext .ts`, `fmt: npx prettier`, `ci: install test lint`. For a 34-crate Rust repo, `just test` runs **Node bounty tests**, `just lint` runs eslint — the primary task runner cannot build, test, or lint the actual product. A new contributor running the documented `just test` (`README.md#34-35`) exercises none of the Rust code.
+- **GAP 2 — Quick start sends contributors down the Node path** (`README.md#25-39`: `npm install` → `just eval` → `just test`). There is no documented `cargo build` / `cargo nextest run` first-run path despite that being how the product builds.
+- **GAP 3 — devcontainer installs Node toolchain via `npm i -g forgecode`** (`devcontainer.json#38`) but does not pre-build the workspace or warm the cargo cache; first `cargo build` of a 144k-LOC workspace will be slow with no guidance/expectation set.
+- Partial credit: good GitHub label surface (`good first issue`, `help wanted`, etc.) per prior scorecard remains valid; devcontainer presence is a real plus.
+
+### Overhaul findings
+
+| # | Gap | Target state | Work items (files) | Acceptance criteria | Effort | Deps | Risk |
+|---|-----|--------------|--------------------|---------------------|--------|------|------|
+| L13-1 | Justfile targets the wrong language | Rust-first task runner; TS targets namespaced | Rewrite `Justfile`: `build: cargo build`, `test: cargo nextest run --workspace`, `lint: cargo +nightly clippy ... -- -D warnings`, `fmt: cargo +nightly fmt --all`, `ci: build test lint`; add `evals-test:`/`evals-lint:` for the Node subtool. | `just test` runs Rust tests; `just ci` mirrors the (new) CI gates; Node targets clearly namespaced. | 3-6 tool calls | L11-1/L11-3 (mirror CI gates) | Low |
+| L13-2 | Quick start is Node-only | README quick start = clone → devcontainer/cargo → `just test` green | Update `README.md#25-39` to lead with Rust first-run; keep evals as secondary. | New contributor reaches a green `just test` (Rust) following only the README. | 2-3 tool calls | L12-1, L13-1 | Low |
+| L13-3 | Devcontainer cold first build | Warm build / set expectations | Add optional `postCreateCommand` step `cargo fetch` (+ note expected first-build time) or a `cargo build` warmup; keep image as-is. | Devcontainer open → `just test` works without manual tool installs; first-build cost documented. | 2-4 tool calls | L13-1 | Low (build time in CI image) |
+| L13-4 | No "good first issue" → code path map | CONTRIBUTING links labels to crates | In `CONTRIBUTING.md`, map common contribution areas to crates (e.g. TUI → `forge_tui`, providers → `forge_services`). | Each `good first issue` area has a named starting crate. | 2-3 tool calls | L12-4 | Low |
+
+---
+
+## Top 3 highest-leverage overhauls
+
+1. **L12-1 + L12-2 — De-drift the README and SSOT to describe the real Rust workspace.** The single biggest credibility/onboarding failure across the whole cluster: the two most-authoritative docs (`README.md#1-44`, `docs/SSOT.md#1-28`) describe a TypeScript "evals" project with `Rust: N/A` while the repo is 144k LOC of Rust across 34 crates. Fixing this lifts L12 the most and unblocks every other doc/onboarding fix. ~6-10 tool calls, low risk.
+
+2. **L11-1 + L11-3 — Add real *gating* test and lint jobs to CI.** Today tests run only as a side-effect of coverage generation and clippy/fmt only run inside an auto-committing fixer (`ci.yml#37-56`, `autofix.yml#52-57`) — nothing actually *blocks* a PR on a failing test or unfixable lint. Adding a required `cargo nextest run` job + a non-mutating clippy/fmt `--check` gate converts a large existing test suite (277 test files, 170 snapshots) from decorative to enforcing. Must edit the gh-workflow generator, not the generated YAML. ~6-10 tool calls, low risk.
+
+3. **L13-1 — Rewrite the Justfile to drive the Rust workspace.** The primary task runner is 100% Node (`Justfile#9-33`); `just test`/`just lint` never touch the product. Making `just test`/`just ci` run `cargo nextest`/clippy aligns local DX with the (new) CI gates and the existing good devcontainer, giving contributors a true one-command path. ~3-6 tool calls, low risk.

+# forgecode — W07 Deep Audit (L18 / L19 / L20 / L28)
+
+> Cluster W07 mean **1.38/3.0**. Pillars: L18 (secrets handling), L19 (supply-chain
+> integrity), L20 (threat model / trust boundaries), L28 (dependency hygiene).
+> Audited against canonical `main` @ `536bb23b847a` on 2026-06-28.
+> **Planning audit only — no source was modified.** All citations are real files.
+
+forgecode is a fork of `tailcallhq/forgecode`: a 34-entry Rust workspace
+(`crates/*` + `forge3d`, `ghostty-kit`) shipping a CLI/TUI AI coding agent with
+multi-provider LLM auth (Anthropic, OpenAI, Bedrock, Google ADC, OAuth, MCP).
+It is a credential-handling client binary, not a server — this reframes every
+pillar away from "runtime secret-manager" toward "local credential hygiene +
+release supply chain."
+
+---
+
+## L18 — Secrets Handling (scored 1.5/3.0)
+
+**What it measures:** How secrets enter, live, and leave the system — CI secret
+scanning, `.env` discipline, at-rest protection of credentials, redaction in
+logs/errors, and a rotation story.
+
+**Current state (evidence):**
+
+- CI secret scanning present: [`.github/workflows/trufflehog.yml#L22`](../../../../.github/workflows/trufflehog.yml) runs `trufflehog github --only-verified` on push+PR with pinned checkout SHA.
+- `.env` is gitignored: [`.gitignore#L24`](../../../../.gitignore).
+- At-rest credential file IS permission-hardened to `0o600`: [`crates/forge_repo/src/provider/provider_repo.rs#L595-L617`](../../../../crates/forge_repo/src/provider/provider_repo.rs) (`set_owner_only_permissions`), with a regression test at `#L1308-L1343`. This is **better than the scorecard implied** and should be credited.
+- Env→file migration path exists (`migrate_env_credentials`) so keys move out of shell env into the managed store: [`crates/forge_repo/src/provider/provider_repo.rs#L664`](../../../../crates/forge_repo/src/provider/provider_repo.rs).
+- `ApiKey` redacts on `Display`: [`crates/forge_domain/src/auth/new_types.rs#L9-L41`](../../../../crates/forge_domain/src/auth/new_types.rs) (`truncate_key`).
+
+**Real gaps found:**
+
+### Finding L18-1 — Secrets leak through `Debug` formatting
+- **Gap:** `ApiKey` redacts `Display` but **derives `Debug`** ([`new_types.rs#L3-L7`](../../../../crates/forge_domain/src/auth/new_types.rs)), so `{:?}` prints the full key. Worse, `AuthCredential`, `AuthDetails`, and the OAuth token types all `#[derive(Debug)]` with no redaction ([`credentials.rs#L9, #L85, #L119`](../../../../crates/forge_domain/src/auth/credentials.rs)). Any `tracing::debug!("{cred:?}")`, `anyhow` context, panic, or `unwrap` on a struct containing these spills plaintext access tokens/refresh tokens/API keys into logs and the PostHog tracker (`forge_tracker`).
+- **Target state:** No secret value is reachable via `Debug`, `Display`, serde-to-log, or panic for any auth type.
+- **Work items:** In `crates/forge_domain/src/auth/`: replace `#[derive(Debug)]` on `ApiKey`, `AccessToken`, `RefreshToken`, `AuthorizationCode`, `DeviceCode`, `PkceVerifier`, `AuthCredential`, `AuthDetails`, `OAuthTokens` with hand-written `Debug` impls emitting `ApiKey("***")` / `AccessToken(redacted)`. Wrap underlying `String` in a `Secret<String>` newtype (wrap `secrecy` crate — `// wraps: secrecy`) so the leak is structurally impossible. Audit the two `tracing::warn!(... e)` call sites in [`mcp_client.rs#L233-L236`](../../../../crates/forge_infra/src/auth/../mcp_client.rs) for error chains carrying tokens.
+- **Acceptance:** New unit tests in `forge_domain` assert `format!("{:?}", ApiKey::from("sk-secretvalue123456789"))` contains neither the key nor any 4+ char substring of it; same for `AuthCredential` with OAuth tokens. `grep -rn "derive.*Debug" crates/forge_domain/src/auth` shows zero secret types with raw derive.
+- **Effort:** ~6 tool calls / ~5 min (1 crate, ~8 type edits + tests).
+- **Dependencies:** none.
+- **Risk:** Low. Mechanical; `secrecy` may need `serde` feature for the `#[serde(transparent)]` round-trip — verify token persistence still deserializes.
+
+### Finding L18-2 — `.credentials.json` not gitignored; no rotation story
+- **Gap:** Credentials persist as **plaintext JSON** at `environment.credentials_path()` ([`provider_repo.rs#L583-L605`](../../../../crates/forge_repo/src/provider/provider_repo.rs)). `0o600` protects against other local users but not against backup tools, sync clients, or a path misconfiguration that lands the file inside the repo. `.gitignore` ([`.gitignore#L43-L49`](../../../../.gitignore)) does **not** list `.credentials.json` / `*credentials*`. There is no rotation/expiry enforcement for long-lived `ApiKey` credentials (`needs_refresh` returns `false` for `ApiKey`, [`credentials.rs#L62`](../../../../crates/forge_domain/src/auth/credentials.rs)) and no OS-keychain backend (`grep keyring|secret-service` → NONE).
+- **Target state:** Plaintext credential file can never be committed; optional OS-keychain storage; documented rotation guidance.
+- **Work items:** (a) Add `**/.credentials.json` and `*credentials*.json` to `.gitignore`. (b) New optional backend in `crates/forge_infra/src/auth/` wrapping the `keyring` crate (`// wraps: keyring`) selected via `forge.toml`, falling back to the `0o600` file. (c) Document rotation + storage in a new `docs/security/secrets.md` and link from `CLAUDE.md` § Security.
+- **Acceptance:** `git check-ignore .credentials.json` passes; keyring backend round-trips a credential in an integration test gated behind a feature flag; docs page exists and is linked.
+- **Effort:** ~10 tool calls / 1 subagent / ~8 min.
+- **Dependencies:** L18-1 (`Secret` newtype) lands first so keyring stores wrapped values.
+- **Risk:** Medium. `keyring` is platform-specific (libsecret on Linux CI may be absent) — keep it opt-in and feature-gated so it never breaks the default build/test.
+
+---
+
+## L19 — Supply-Chain Integrity (scored 2.0/3.0)
+
+**What it measures:** Build provenance, artifact signing, SBOM emission, vuln
+scanning of dependencies, and reproducibility of releases.
+
+**Current state (evidence):**
+
+- SLSA Build L2 provenance is genuinely wired: [`.github/workflows/release-attestation.yml#L83-L87`](../../../../.github/workflows/release-attestation.yml) uses `slsa-framework/slsa-github-generator/attest-build-provenance@v1`; documented honestly with an L3 roadmap in [`docs/slsa.md`](../../../../docs/slsa.md).
+- `cargo-deny` advisory+license gate on every PR: [`.github/workflows/cargo-deny.yml#L21-L22`](../../../../.github/workflows/cargo-deny.yml).
+- Builds use `--locked` ([`release-attestation.yml#L44`](../../../../.github/workflows/release-attestation.yml)) — lockfile-pinned.
+
+**Real gaps found:**
+
+### Finding L19-1 — No SBOM emitted or attested
+- **Gap:** Zero SBOM tooling in the repo: `grep -rilE "sbom|cyclonedx|spdx|syft" .github/` → **NONE**. The release attests *provenance* but ships no machine-readable dependency manifest, so downstream consumers cannot diff dependencies or run their own vuln correlation against a forgecode release.
+- **Target state:** Every release attaches a CycloneDX SBOM, itself covered by an attestation.
+- **Work items:** Add a step to `release-attestation.yml` running `cargo cyclonedx --format json --all` (wraps `cargo-cyclonedx`) into `release-artifacts/sbom.cdx.json`; include it in the `attest-build-provenance` artifact set (or a second `actions/attest-sbom` step). Update [`docs/slsa.md`](../../../../docs/slsa.md) provenance-contents table to list the SBOM.
+- **Acceptance:** A `workflow_dispatch` run produces `sbom.cdx.json` listing all 34 workspace crates + transitive deps; `gh attestation verify` succeeds against it.
+- **Effort:** ~4 tool calls / ~4 min.
+- **Dependencies:** none.
+- **Risk:** Low. `cargo-cyclonedx` install adds ~1 min to release CI only.
+
+### Finding L19-2 — No continuous vulnerability scanning of the dependency graph
+- **Gap:** `cargo-deny` checks the RustSec advisory DB, but there is no OSV/Trivy/Grype scan and no scheduled re-scan — advisories published *after* a merge are never re-evaluated until the next PR touches deps. No `schedule:` trigger on `cargo-deny.yml` (push/PR/dispatch only).
+- **Target state:** Daily scheduled vuln scan over the committed `Cargo.lock` with results in the GitHub Security tab.
+- **Work items:** Add `schedule: - cron: '0 6 * * *'` to `cargo-deny.yml`; add an `osv-scanner` job (`google/osv-scanner-action`) emitting SARIF uploaded via `github/codeql-action/upload-sarif`. Cross-link from `CLAUDE.md` § Security.
+- **Acceptance:** A scheduled run appears in the Actions tab; an OSV SARIF result is visible in Security → Code scanning; the job fails on a known-vulnerable injected fixture in a dry-run branch.
+- **Effort:** ~5 tool calls / ~4 min.
+- **Dependencies:** none (independent of L19-1).
+- **Risk:** Low. (Note: GH Actions billing constraint — these are standard Linux runners, acceptable per repo policy.)
+
+---
+
+## L20 — Threat Model / Trust Boundaries (scored 0.5/3.0 — weakest pillar)
+
+**What it measures:** A real attack-surface analysis: trust boundaries, data
+flows, assets, adversaries, and how each crossing is defended.
+
+**Current state (evidence):**
+
+- The only boundary artifact is a **generated stub with three `TODO`s** and no content: [`docs/boundary/forgecode.md#L13-L25`](../../../../docs/boundary/forgecode.md). It is explicitly `do-not-edit-locally` (propagated from `phenotype-registry`), so the SSOT lives in another repo and forgecode has never had a real threat model authored.
+
+**Real gaps found:**
+
+### Finding L20-1 — No threat model exists for a credential-handling agent
+- **Gap:** forgecode handles provider API keys + OAuth tokens, spawns subprocesses (`forge_infra/src/executor.rs`), runs MCP subprocess/SSE/HTTP transports (`forge_infra/src/mcp_client.rs`), executes a ZSH plugin (`forge_main/src/zsh/plugin.rs`), and pipes untrusted LLM output into a tool-execution loop. **None** of these trust boundaries are documented or analyzed. The stub's `## In Scope / Out of Scope / Crossings` are empty TODOs.
+- **Target state:** A concrete threat model covering: (1) credential store (L18 assets), (2) subprocess/tool execution from LLM-controlled input (prompt-injection → command execution), (3) MCP server trust (a malicious MCP server returning crafted auth-error flows — see the auto-credential-retry logic at [`mcp_client.rs#L147-L240`](../../../../crates/forge_infra/src/auth/../mcp_client.rs)), (4) the PostHog telemetry egress (`forge_tracker`), (5) ZSH plugin injection.
+- **Work items:** Author `docs/security/threat-model.md` (do NOT edit the propagated stub; instead fill the registry SSOT or add a local non-propagated doc) using STRIDE per boundary. Build a data-flow diagram (Mermaid) showing: user → CLI → credential store (0o600) → provider HTTP; LLM → tool loop → subprocess executor; MCP transports. For each crossing list the asset, threat, current control (cite file), and residual risk. Update [`docs/boundary/forgecode.md`](../../../../docs/boundary/forgecode.md) In/Out/Crossings via the registry pipeline so the stub stops being a TODO.
+- **Acceptance:** `threat-model.md` enumerates ≥5 trust boundaries each with ≥1 STRIDE threat and a cited control or a tracked gap; the Mermaid diagram renders; `docs/boundary/forgecode.md` has no remaining `TODO` markers.
+- **Effort:** 1 subagent / ~12 min (analysis-heavy: trace executor + mcp_client + tracker egress).
+- **Dependencies:** Informs L18 (assets) and L19 (build boundary) — best authored after L18 findings are catalogued so controls can be cited.
+- **Risk:** Low (documentation), but high *leverage* — this is the 0.5 pillar dragging the cluster mean.
+
+### Finding L20-2 — Prompt-injection → tool-execution boundary undefended
+- **Gap:** The agent feeds LLM output into a tool/subprocess execution path (`forge_infra/src/executor.rs`, tool macros in `forge_tool_macros`). No documented allowlist, sandbox, or confirmation boundary was found for shell/file-mutating tools driven by model output. This is the highest-severity attack surface for an AI coding agent.
+- **Target state:** Documented + enforced execution-confirmation / allowlist boundary for model-initiated side effects.
+- **Work items:** (a) In `threat-model.md`, document the current confirmation flow (audit `forge_main/src/ui.rs` + executor for existing prompts). (b) If no enforcement exists, file a tracked work item to gate destructive tool calls behind explicit user confirmation or a configurable allowlist. (Audit-scoped: document + ticket; do not implement here.)
+- **Acceptance:** Boundary documented with the exact files implementing (or lacking) the control; a follow-up issue exists if a gap is confirmed.
+- **Effort:** included in L20-1's subagent (~3 extra tool calls).
+- **Dependencies:** L20-1.
+- **Risk:** Low to document; the *underlying* gap (if unenforced) is High severity — flag prominently.
+
+---
+
+## L28 — Dependency Hygiene (scored 1.5/3.0)
+
+**What it measures:** Lockfile discipline, advisory enforcement, license policy,
+update automation, and absence of conflicting/over-broad bots.
+
+**Current state (evidence):**
+
+- Lockfile committed + `--locked` builds; `cargo-deny` enforced ([`cargo-deny.yml`](../../../../.github/workflows/cargo-deny.yml)); thorough license allowlist + `wildcards = "deny"`, `unknown-git = "deny"` ([`deny.toml#L4-L52`](../../../../deny.toml)).
+- Dependabot ([`.github/dependabot.yml`](../../../../.github/dependabot.yml)) AND Renovate ([`renovate.json`](../../../../renovate.json)) are **both active**.
+
+**Real gaps found:**
+
+### Finding L28-1 — Two update bots running simultaneously (Dependabot + Renovate)
+- **Gap:** [`dependabot.yml`](../../../../.github/dependabot.yml) (weekly cargo+actions, grouped) and [`renovate.json`](../../../../renovate.json) (`config:recommended` + `automerge:true` + `platformAutomerge:true`) overlap — they will open duplicate/competing PRs against the same `Cargo.toml`. Renovate's blanket `automerge:true` will auto-merge dependency bumps **with no human gate**, which on a fork tracking a fast-moving upstream is a supply-chain risk (a compromised transitive release could auto-land). The scorecard flagged "update bots overlap" and "no single clear strategy."
+- **Target state:** Exactly one update bot, with automerge restricted to patch/dev-dep updates that pass full CI.
+- **Work items:** Choose Renovate (richer Rust support) and **delete `.github/dependabot.yml`**, or keep Dependabot and delete `renovate.json`. If keeping Renovate, replace blanket `automerge:true` with a `packageRules` policy that automerges only `patch` + `pin` updates and requires `cargo-deny` + `ci` status checks; disable automerge for `major`/`minor`. Document the chosen strategy in `CLAUDE.md` § Security/Dependencies.
+- **Acceptance:** Only one bot config remains in the repo; Renovate dry-run (`renovate-config-validator`) passes; no automerge rule applies to major/minor; CLAUDE.md states the single strategy.
+- **Effort:** ~3 tool calls / ~3 min.
+- **Dependencies:** none.
+- **Risk:** Medium-low. Removing a bot is reversible; the real risk being *removed* is unattended automerge.
+
+### Finding L28-2 — Nine advisories ignored; no expiry/review cadence
+- **Gap:** [`deny.toml#L27-L43`](../../../../deny.toml) ignores 9 RUSTSEC advisories. Five (`RUSTSEC-2026-0118/0119/0098/0099/0104`) carry **no `reason`** ("Pre-existing fork-specific ignores (preserve)") — violating the workspace suppression policy (every ignore needs rule + justification + tracking ref). There is no dated review cadence, so ignores accumulate silently.
+- **Target state:** Every advisory ignore has a reason + tracking issue + review date; unmaintained-dep ignores are re-evaluated on upstream sync.
+- **Work items:** For each of the 5 unreasoned IDs, add a `reason = "..."` with a tracking issue URL (or remove if the advisory no longer resolves — note line 42 already documents one such removal). Add a quarterly review checklist to `docs/security/secrets.md`/threat-model. Optionally add `[advisories] unmaintained = "workspace"` to scope noise to direct deps.
+- **Acceptance:** `cargo deny check advisories` passes; zero ignore entries lack a `reason`; each maps to a tracked issue.
+- **Effort:** ~4 tool calls / ~4 min (some advisory lookup).
+- **Dependencies:** none.
+- **Risk:** Low. Removing a stale ignore could surface a real advisory failure — that is the intended signal.

+## Summary
+
+| Pillar | Score | One-line gap |
+|--------|-------|--------------|
+| L18 | 1.5 | Secrets leak via `Debug` derive; plaintext credential file not gitignored, no keychain/rotation. |
+| L19 | 2.0 | SLSA L2 provenance exists but no SBOM emission and no continuous OSV/scheduled vuln scan. |
+| L20 | 0.5 | Boundary doc is an empty TODO stub; no threat model for credential store, prompt-injection→exec, or MCP trust. |
+| L28 | 1.5 | Dependabot + Renovate both active (Renovate blanket automerge); 5 unreasoned advisory ignores, no review cadence. |
+
+**Total findings: 8** (L18: 2, L19: 2, L20: 2, L28: 2).
+
+## Top 3 highest-leverage overhauls
+
+1. **L20-1 + L20-2 — Author the real threat model.** L20 is the 0.5 anchor dragging the cluster mean; a single ~12-min subagent doc (STRIDE over the 5 trust boundaries: credential store, prompt-injection→subprocess exec, MCP server trust, telemetry egress, ZSH plugin) moves the weakest pillar the most and reframes/justifies every other W07 fix. Highest score-per-effort.
+2. **L18-1 — Redact secrets in `Debug` / wrap in `Secret<String>`.** ~5-min mechanical change in one crate that closes a live plaintext-credential leak into logs/PostHog telemetry — the most concrete *security* (not paperwork) win, and a prerequisite the threat model will cite.
+3. **L28-1 — Collapse to one update bot and kill blanket automerge.** ~3-min config change that removes an unattended supply-chain auto-merge risk on a fast-moving fork and resolves the L28 + L19 "no single strategy" findings together.

+# W12 Deep Audit — forgecode (L34 / L35 / L36 / L37)
+
+**Repo:** `/Users/kooshapari/CodeProjects/Phenotype/repos/forgecode` (canonical `main`, 34-crate Rust workspace; vestigial TS evals subsystem)
+**Date:** 2026-06-28
+**Prior scorecard:** `.audit-run-v37/out/forgecode/W12.md` — mean 1.15 (L34 1.0 / L35 2.2 / L36 2.1 / L37 0.3)
+**Scope:** PLANNING audit. No source modified. All citations are real paths verified during this audit.

+
+## Pillar measurement summary
+
+| Pillar | What it measures | Prior | Current gap (one-liner) |
+|--------|------------------|-------|-------------------------|
+| **L34** | Docs / journeys / diagrams / media richness; README depth; docsite | 1.0 | Root README/SSOT/Justfile describe a **different (TS) project**; zero diagrams/screenshots/video; no docsite; journey manifests empty (0/4). |
+| **L35** | Meta-ecosystem / shared-code reuse vs duplication | 2.2 | Internal layering is excellent, but forgecode **independently re-implements provider model lists, OAuth2+token-refresh, retry/backoff, SSE stop-signal detection** also present in OmniRoute & cliproxyapi-plusplus (~3.5–5.5k LOC dup). |
+| **L36** | Quality-polish / QOL (CLI, errors, shell, CI, dev tooling) | 2.1 | Strong CLI/Windows/shell polish undercut by a **user-facing `panic!` on bad `--directory`**, **no `fmt`/`clippy` CI gates**, and a **Node Justfile** in a Rust repo. |
+| **L37** | Stub / empty / in-progress / dead-code detection | 0.3 | 1 **production** `unimplemented!()` (openai http_delete), a **NoopIntentExtractor** that errors, a **non-functional `forge_dbd` daemon**, 1 **dead crate** (`ghostty-kit`), and 4 stub governance docs. |

+
+## L34 — Docs / Journeys / Media Richness
+
+### Finding L34-1 — Root README, SSOT, and Justfile describe the WRONG project
+- **Gap:** `README.md#L1-3` titles the repo "ForgeCode Evals — TypeScript evaluation and bounty-cli tooling"; `README.md#L13-23` documents a hexagonal `src/domain|ports|adapters|app` TS layout that does not exist; `README.md#L25-44` quick-start is npm-only (no `cargo build`). `docs/SSOT.md#L5-6` lists `Rust: N/A` for a ~144k-LOC Rust workspace and `docs/SSOT.md#L16-21` references `ProviderPort/StoragePort/GithubApiAdapter` not present in `crates/`. (Also surfaces in L36 via `Justfile#L9-23`.)
+- **Target state:** README, SSOT, and CLAUDE/AGENTS agree: Rust CLI is the product; TS evals is a clearly-labeled subsystem. A new reader gets correct language, crate map, and `cargo` build path within 30s.
+- **Work items:** Rewrite `README.md` (Rust-first: install via `cargo install`/release binary, crate-map table, `forge` quick start); rewrite `docs/SSOT.md` (real deps, real crate list, refresh `Last verified`); make `docs/index.md` a true precedence map (SSOT > ADR > AGENTS > CONTRIBUTING > README). Reuse the accurate crate map already in `CLAUDE.md#L1-133` and `AGENTS.md`.
+- **Acceptance:** README mentions zero npm-as-primary; SSOT lists Rust as primary with ≥20 crates enumerated; `docs/index.md` links boundary/intent/ADR/SSOT/sessions.
+- **Effort:** 4–6 tool calls (~3 min).
+- **Dependencies:** None (content already exists in CLAUDE.md/Cargo.toml). Pairs with L36-3 (Justfile).
+- **Risk:** Low.
+
+### Finding L34-2 — Zero media richness (no diagrams, screenshots, video)
+- **Gap:** No ` ```mermaid` blocks anywhere in `docs/`; no `.png/.jpg/.gif/.svg/.mp4/.webm` assets in the repo. README architecture is text-only. forge-dev UI crates (`forge_tui`, `forge_display`) ship no README or screenshots.
+- **Target state:** At least one architecture diagram (crate dependency / request flow), one TUI screenshot or VHS-recorded cast, and a journey GIF for the primary `forge` flow.
+- **Work items:** Add a Mermaid crate-layering + request-flow diagram to README/`docs/architecture/`; record a `vhs` tape for the main interactive session and the `forge_select` picker; add `forge_tui`/`forge_display` READMEs with embedded screenshots; commit assets under `docs/assets/`.
+- **Acceptance:** ≥1 mermaid diagram renders in README; ≥1 image asset committed; `forge_tui` has a README with a screenshot.
+- **Effort:** 8–12 tool calls + manual capture (~6–8 min); diagram alone is 2–3 calls.
+- **Dependencies:** L34-1 (don't decorate a wrong README first).
+- **Risk:** Low.
+
+### Finding L34-3 — User-journey surface is empty / stubbed
+- **Gap:** `docs/journeys/manifests/README.md#L1` is a single header (empty); `docs/operations/journey-traceability.md#L9-14` is a 0/4 checklist (no flows identified, no VHS tapes, no manifests, no CI verification). (Overlaps L37 stub docs.)
+- **Target state:** ≥3 documented user journeys (first-run/auth, interactive coding session, conversation resume) each with a manifest + traceability entry + recorded tape.
+- **Work items:** Author journey manifests under `docs/journeys/manifests/`; check off `journey-traceability.md` items as flows are added; wire a CI check that asserts each manifest has a corresponding tape.
+- **Acceptance:** 3 non-empty manifests; traceability checklist ≥3/4 complete.
+- **Effort:** 6–10 tool calls (~5 min) + tape capture.
+- **Dependencies:** L34-2 (tapes).
+- **Risk:** Low.
+
+### Finding L34-4 — Empty CHANGELOG / stub CONTRIBUTING
+- **Gap:** `CHANGELOG.md#L8-21` has no entries (template only); `CONTRIBUTING.md#L14` is hedged/generic ("`cargo fmt` … *or the appropriate linter for your stack*") with no concrete Rust workflow. (Strong counter-evidence: `AGENTS.md` 246 lines, `docs/adr/0001-*.md` 206 lines, `docs/slsa.md` 125 lines are genuinely good.)
+- **Target state:** Keep-a-Changelog with real `[Unreleased]` entries; CONTRIBUTING with concrete `cargo` build/test/clippy/deny commands and fixture conventions.
+- **Work items:** Backfill CHANGELOG from git history; rewrite CONTRIBUTING to cite `cargo test --workspace`, `cargo clippy`, `cargo deny check`, and the 3-step test convention from `AGENTS.md`.
+- **Acceptance:** CHANGELOG `[Unreleased]` non-empty; CONTRIBUTING contains no "or your stack" hedge and only Rust commands.
+- **Effort:** 3–4 tool calls (~2 min).
+- **Dependencies:** None.
+- **Risk:** Low.
+
+---
+
+## L35 — Meta-Ecosystem / Shared-Code
+
+### Finding L35-0 (positive baseline) — Internal layering is clean
+- **Evidence:** `crates/forge_domain/src/lib.rs#L1-57`, `crates/forge_infra/src/lib.rs#L1-28`, `crates/forge_config/src/lib.rs#L1-37` form a deliberately reused foundation consumed by `forge_app`/`forge_services`; no intra-workspace crate duplicates another. This is why L35 already scores 2.2. Preserve this; the gaps below are *cross-repo*, not intra-repo.
+
+### Finding L35-1 — Provider model lists + DTO normalization triplicated across repos
+- **Gap:** `crates/forge_app/src/dto/{anthropic,google,openai}/response.rs` and `utils.rs` (`sanitize_gemini_schema`) maintain provider model lists + schema normalization that are independently re-implemented in OmniRoute (`open-sse/translator/gemini.ts`, `src/shared/constants/providers.ts`) and cliproxyapi-plusplus (`pkg/llmproxy/executor/{gemini_executor.go,openai_models_fetcher.go}`). ~1.5–2k LOC of parallel maintenance.
+- **Target state:** Single Phenotype source-of-truth for provider/model registry + schema-normalization rules; language clients consume generated artifacts.
+- **Work items:** Create `phenotype-provider-models` (Rust crate owning the registry + transforms; emits JSON for TS/Go). Migrate forgecode `dto/*/response.rs` model lists to consume it; export JSON for OmniRoute; document enum for cliproxyapi sync.
+- **Acceptance:** forgecode model lists sourced from the shared crate; OmniRoute imports the generated JSON; no per-repo hand-edited model tables.
+- **Effort:** Cross-stack — 2–3 parallel subagents (~2–3 days agent-time). Confirm destination repo with sponsor (cross-repo move per reuse protocol).
+- **Dependencies:** Sponsor sign-off on shared-crate location.
+- **Risk:** Low (pure data + transforms), Medium logistically (3 languages).
+
+### Finding L35-2 — OAuth2 + token-refresh duplicated (identical 5-min buffer)
+- **Gap:** `crates/forge_infra/src/auth/strategy.rs`, `crates/forge_infra/src/auth/util.rs#L51-80`, and `crates/forge_services/src/provider_auth.rs#L146-213` implement OAuth2 flows + a 5-minute refresh buffer that is *byte-for-byte conceptually identical* to OmniRoute (`src/lib/oauth/`, `open-sse/services/auth.ts`) and cliproxyapi (`pkg/llmproxy/auth/oauth_token_manager.go`). ~600–800 LOC.
+- **Target state:** Shared OAuth orchestration + token-lifecycle policy (buffer, refresh, mark-unavailable) with per-language thin adapters.
+- **Work items:** Extract `phenotype-oauth` (Rust core: flow + expiry + refresh policy; credential-storage trait). Rewire `provider_auth.rs` to consume it.
+- **Acceptance:** Refresh-buffer constant defined once; forgecode auth tests pass against shared crate.
+- **Effort:** 3–4 days agent-time; auth needs thorough test coverage.
+- **Dependencies:** L35-1 pattern validated first; sponsor sign-off on location.
+- **Risk:** Medium (auth correctness/security).
+
+### Finding L35-3 — Retry/backoff (+ missing circuit breaker) and SSE stop-signal detection duplicated
+- **Gap:** `crates/forge_app/src/retry.rs#L7-29` (backon `ExponentialBuilder`) and `crates/forge_infra/src/http.rs#L1-127` duplicate resilience logic in OmniRoute (`src/shared/utils/circuitBreaker.ts`, `open-sse/services/accountFallback.ts`); forgecode notably *lacks* the circuit breaker OmniRoute has. Separately, `crates/forge_eventsource_stream/src/parser.rs#L1-124` re-derives stop-signal detection (`message_stop`/`finish_reason`/`finishReason`) also in OmniRoute `open-sse/lib/sseTextTransform.ts`. ~600–900 LOC combined.
+- **Target state:** Shared resilience primitives (retry + backoff + circuit breaker) and a shared SSE stop-signal taxonomy; forgecode *gains* the circuit breaker.
+- **Work items:** Extract `phenotype-resilience` and `phenotype-sse` (Rust crates, optional WASM export for TS). Adopt circuit breaker in `forge_infra/src/http.rs`.
+- **Acceptance:** forgecode HTTP path has a circuit breaker; SSE stop-signal table defined once.
+- **Effort:** 2–3 days agent-time (resilience) + 1–2 days (SSE).
+- **Dependencies:** L35-1/L35-2 to establish the shared-crate pattern.
+- **Risk:** Low (stable patterns).
+
+---
+
+## L36 — Quality-Polish / QOL
+
+### Finding L36-0 (positive baseline) — Real polish already present
+- **Evidence:** `crates/forge_main/src/cli.rs` (version via `#[command(version=…)]` L15, aliases L41-42, `--porcelain` in 17+ sites); `crates/forge_main/src/main.rs#L34-45` Windows VT/ANSI handling; comprehensive 9-module `shell-plugin/` with clap-generated completions (`crates/forge_main/src/zsh/plugin.rs#L19-50`); rich `forge_config` defaults. This is why L36 scores 2.1.
+
+### Finding L36-1 — User-facing `panic!` on invalid working directory
+- **Gap:** `crates/forge_main/src/main.rs#L135` `panic!("Invalid path: {}", cli.display())` fires on a bad `--directory`, producing an ugly backtrace instead of a clean error; `main.rs#L137` silently falls back to `.` if `current_dir()` fails (no warning) — violates the no-silent-degradation rule.
+- **Target state:** Invalid working dir returns a contextual `anyhow` error; `current_dir()` failure surfaces a clear message.
+- **Work items:** Replace `panic!` with `anyhow::bail!("Invalid working directory: …")`; add `.context()` to the `current_dir()` fallback.
+- **Acceptance:** `forge --directory /nonexistent` prints a one-line error, exit code ≠ panic; no bare `unwrap_or_else(|_| ".")` without a warning.
+- **Effort:** 1–2 tool calls (~1 min).
+- **Dependencies:** None.
+- **Risk:** Low.
+
+### Finding L36-2 — CI lacks `fmt`/`clippy` gates
+- **Gap:** `.github/workflows/ci.yml` runs `cargo llvm-cov` but enforces neither `cargo fmt --check` nor `cargo clippy --all-targets -- -D warnings`; no `.pre-commit-config.yaml`. `clippy.toml`/`.rustfmt.toml` exist but are unenforced in CI.
+- **Target state:** CI fails on unformatted code or clippy warnings; optional local pre-commit mirrors it. (Use standard Linux runner only — billing constraint.)
+- **Work items:** Add `fmt` + `clippy -D warnings` jobs to `ci.yml`; add `.pre-commit-config.yaml` running `cargo fmt`/`clippy`.
+- **Acceptance:** A formatting or clippy violation reddens CI on Linux runner.
+- **Effort:** 3–4 tool calls (~2 min).
+- **Dependencies:** Clean current clippy/fmt state first (may surface debt — must fix, not suppress).
+- **Risk:** Medium (may expose pre-existing warnings that must be fixed, not ignored).
+
+### Finding L36-3 — Justfile targets Node/npm in a Rust workspace
+- **Gap:** `Justfile#L9-23` (`install: npm install`, `test: npm run test:bounty`, `lint: npx eslint`) — the primary task runner cannot build/test/lint the actual product; `Justfile#L2` hardcodes bash (breaks Windows). A new contributor following README runs zero Rust.
+- **Target state:** `just test/lint/fmt/build` drive `cargo` across the workspace.
+- **Work items:** Rewrite `Justfile` to `cargo test --workspace`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo fmt --check`, `cargo build --release`; keep TS-evals targets under a clearly-namespaced recipe (e.g. `evals-test`).
+- **Acceptance:** `just test` builds/tests Rust; npm recipes are namespaced, not the default.
+- **Effort:** 2–3 tool calls (~2 min). Pairs with L34-1.
+- **Dependencies:** None.
+- **Risk:** Low.
+
+### Finding L36-4 — Unwrap/expect density + missing color controls
+- **Gap:** ~111 `.unwrap()` / ~18 `.expect()` in `forge_main`; runtime-path examples include `crates/forge_main/src/conversation_selector.rs` `ConversationId::parse().unwrap()`. No `--color=auto|always|never` flag; `NO_COLOR` is actively *stripped* (`crates/forge_infra/src/executor.rs#L43-44`) and not honored in the UI. No `miette`/`color-eyre` rich diagnostics.
+- **Target state:** Runtime-path unwraps converted to contextual errors; standard `--color` flag; `NO_COLOR` honored.
+- **Work items:** Audit `forge_main` runtime (non-test) unwraps and convert to `?`/`context`; add a global `--color` arg; honor `NO_COLOR` in the UI color decision.
+- **Acceptance:** `NO_COLOR=1 forge …` emits no ANSI; `--color=never` works; no `unwrap()` on parsed user input in runtime paths.
+- **Effort:** 6–10 tool calls (~5 min).
+- **Dependencies:** None.
+- **Risk:** Low.
+
+---
+
+## L37 — Stub / Empty / In-Progress Detection
+
+### Finding L37-1 — Production `unimplemented!()` in OpenAI responses repo
+- **Gap:** `crates/forge_repo/src/provider/openai_responses/repository.rs#L573` — `http_delete()` is `unimplemented!()` in a **non-test** `HttpClient` impl. (Contrast: the 16 other `unimplemented!()` hits are in mock/test fixtures — acceptable.)
+- **Target state:** Either implement `http_delete()` or make the trait method `Option`/clearly unsupported with a typed error, never a panic.
+- **Work items:** Implement the delete path (mirror sibling providers' `http_delete`) or return a `ProviderError::Unsupported`.
+- **Acceptance:** No `unimplemented!()` in `forge_repo` production code; a test exercises the delete path or asserts the typed-unsupported error.
+- **Effort:** 2–4 tool calls (~3 min).
+- **Dependencies:** None.
+- **Risk:** Low–Medium (depends if delete is actually called).
+
+### Finding L37-2 — `NoopIntentExtractor` returns errors (feature wired to nothing)
+- **Gap:** `crates/forge_domain/src/intent.rs#L56,75,96` "Real implementation will be provided by thegent-memory v2"; `intent.rs#L119,129` `NoopIntentExtractor` returns "IntentExtractor not implemented" from `extract_intent()`/`verify_extraction()`. The intent surface exists but is non-functional.
+- **Target state:** Either integrate thegent-memory v2 or feature-gate the intent surface so it's not silently dead.
+- **Work items:** Decide: wire thegent-memory v2 dependency, OR put intent behind a `#[cfg(feature="intent")]` gate (off by default) and document status in CHANGELOG/SSOT.
+- **Acceptance:** No runtime call lands on a Noop that errors; status is documented.
+- **Effort:** 2–3 tool calls to gate (~2 min); full integration is a separate epic depending on thegent-memory.
+- **Dependencies:** thegent-memory v2 availability (cross-repo).
+- **Risk:** Medium (cross-repo dependency).
+
+### Finding L37-3 — `forge_dbd` daemon is non-functional (DB layer stubbed)
+- **Gap:** `crates/forge_dbd/src/client.rs#L13` (TODO: use socket path to connect), `crates/forge_dbd/src/server.rs#L15,176,180,185` (4× TODOs awaiting diesel/forge_repo integration). Crate has **no tests**. Effectively an in-progress daemon shipped in the workspace.
+- **Target state:** Complete the diesel integration + socket wiring with tests, OR exclude `forge_dbd` from the default workspace build until ready (clearly marked in-progress).
+- **Work items:** Finish socket connect + transaction handling and add integration tests; or move to a `members`-excluded / feature-gated state and note in SSOT.
+- **Acceptance:** `forge_dbd` either has passing integration tests or is not in the default build; no silent half-daemon.
+- **Effort:** Gate/exclude: 2–3 tool calls. Full completion: small feature (8–15 calls).
+- **Dependencies:** Single-writer daemon design (`docs/sessions/20260626-forge-sqlite-fix/P3_SINGLE_WRITER_DAEMON.md`).
+- **Risk:** Medium.
+
+### Finding L37-4 — Dead crate `ghostty-kit` + stub `orch_runner` template service
+- **Gap:** `ghostty-kit/src/lib.rs#L1` is a 1-line doc comment (dead crate, no tests); `crates/forge_app/src/orch_spec/orch_runner.rs#L208` `register_template()` is `unimplemented!()` in a `TemplateService` impl on `Runner`.
+- **Target state:** Remove `ghostty-kit` from the workspace (or populate it); implement or remove the `register_template` path.
+- **Work items:** Drop `ghostty-kit` from `Cargo.toml` members if unused (verify no dependents first); implement `register_template` or remove the trait method from `Runner`.
+- **Acceptance:** No 1-line dead crate in members; no `unimplemented!()` in `orch_runner` production path.
+- **Effort:** 2–3 tool calls (~2 min) after dependent check.
+- **Dependencies:** Verify `ghostty-kit` has no consumers.
+- **Risk:** Low.
+
+### Finding L37-5 — Stub governance docs (intent/boundary/journeys)
+- **Gap:** `docs/intent/forgecode.md#L15-19` ("TODO: write a 2-3 sentence intent statement"), `docs/boundary/forgecode.md#L13-26` (3× TODO), `docs/journeys/manifests/README.md#L1` (empty), `docs/operations/journey-traceability.md#L9-14` (0/4). These are the exact signals the L37 pillar penalizes.
+- **Target state:** Intent statement written; boundary in/out-of-scope + crossings filled; journeys non-empty (see L34-3).
+- **Work items:** Fill intent (2–3 sentences sourced from CLAUDE.md product overview); fill boundary scope tables; author journey manifests.
+- **Acceptance:** Zero "TODO" markers remain in `docs/intent`, `docs/boundary`; manifests non-empty.
+- **Effort:** 4–6 tool calls (~3 min). Overlaps L34-3/L34-4.
+- **Dependencies:** None (content derivable from CLAUDE.md/AGENTS.md).
+- **Risk:** Low.
+
+---
+
+## Cross-cutting note
+The L34 doc-mislabeling (L34-1), L36 Justfile (L36-3), and L37 stub docs (L37-5) are **one root cause**: the repo is a fork (`tailcallhq/forgecode`) whose original TS-evals scaffolding was never replaced after the Rust product became primary. Fixing the README/SSOT/Justfile/governance-stubs together is a single coherent "de-fork the docs" overhaul and clears the largest scoring deficits in three pillars at once.
+
+---
+
+## Top 3 highest-leverage overhauls
+
+1. **De-fork the doc/governance surface (clears L34-1, L34-4, L36-3, L37-5 at once).** Rewrite README + SSOT + Justfile to be Rust-first and fill the intent/boundary stubs — all source material already exists in `CLAUDE.md`/`AGENTS.md`/`Cargo.toml`. Single biggest score lift for ~10–14 tool calls; lifts L34 from ~1.0 toward ~2.0 and removes the worst L37 stub signals. Low risk.
+
+2. **Add CI `fmt`+`clippy` gates and kill the production stubs (L36-2, L37-1, L37-3, L37-4).** Implement/remove `openai http_delete`, gate-or-exclude `forge_dbd`, drop `ghostty-kit`, and enforce `cargo fmt --check` + `clippy -D warnings` on the Linux runner. This is the direct path off the 0.3 L37 floor and hardens L36 — the highest-ROI quality work. Medium risk only because clippy may surface debt that must be fixed (not suppressed).
+
+3. **Stand up the first shared Phenotype crate: `phenotype-provider-models` (L35-1).** Extract the triplicated provider/model registry + schema normalization shared with OmniRoute and cliproxyapi-plusplus; it's the lowest-risk, highest-LOC-dedup extraction and establishes the shared-crate pattern that L35-2 (OAuth) and L35-3 (resilience/SSE) then follow. Requires sponsor sign-off on destination per the cross-repo reuse protocol.

+# forgecode — SOTA Agentic Coding CLI Research Dossier
+
+**Date:** 2026-06-29
+**Scope:** Push forgecode (Rust agentic coding CLI/TUI) to state-of-the-art as a product.
+**Type:** Planner / research dossier. No forgecode source changes proposed inline — references and acceptance criteria only.
+**Method:** First-hand competitor web research (WebSearch/WebFetch), arxiv/technical research, and direct reading of forgecode's crates (`forge_domain`, `forge_app`, `forge_services`, `forge_repo`, `forge_main`, …).
+
+---
+
+## 0. forgecode — Grounded Baseline (from the code)
+
+Read directly from the repo at `crates/`:
+
+- **Architecture:** Hexagonal, 33-crate Cargo workspace. Pure domain (`forge_domain`), composition root (`forge_app`), orchestration (`forge_services`), public async-trait API (`forge_api`), infra adapters (`forge_infra`), provider/persistence (`forge_repo`), binary (`forge_main`). Clean ports-and-adapters separation — a genuine architectural strength vs. most competitors.
+- **Agent loop:** `forge_app/src/orch.rs` — `Orchestrator<S>` with `#[async_recursion]`, tool-error tracker (`ToolErrorTracker`), hooks (`Arc<Hook>`), pluggable `MetricsSink`. Real multi-step tool loop.
+- **Agents (multi-persona):** 3 built-in — `forge`, `muse`, `sage` (`forge_domain/src/agent.rs`; defs in `forge_repo/src/agents/{forge,muse,sage}.md`). `AgentId` constants. Reasoning config (effort levels None→High, max_tokens, exclude/enabled).
+- **Tools:** `forge_services/src/tool_services/` — `fs_read`, `fs_write`, `fs_patch`, `fs_remove`, `fs_search`, `fs_undo`, `shell`, `fetch`, `followup`, `plan_create`, `skill`, `image_read`, plus `code_review` (in tool catalog). Tool catalog at `forge_domain/src/tools/catalog.rs`.
+- **MCP:** Full client + manager (`forge_services/src/mcp/{manager,service,tool}.rs`, `forge_infra/src/mcp_client.rs`, `forge_domain/src/mcp_servers.rs`). Tools surface alongside built-ins.
+- **Context engineering:** `forge_domain/src/compact/` — `adaptive_eviction`, `importance`, `prefilter`, `strategy`, `summary`, `metrics`, `history`. This is a real, sophisticated compaction subsystem (above-average vs. peers).
+- **Skills:** `forge_domain/src/skill.rs` + `forge_repo/src/skills/` — markdown skills with resources (Claude-Code-style).
+- **Sessions/memory:** SQLite session store w/ WAL checkpointing + zstd compression, conversation FTS + vector search, subagent breadcrumbs (README; `forge_dbd` session daemon over Unix socket; `forge_embed` embeddings — but `forge_embed/src/hash_only.rs` indicates a **hash-only / non-semantic** embed path).
+- **Providers/routing:** `forge_repo/src/provider/` — Anthropic, OpenAI, OpenAI Responses, Google, Bedrock (+cache/sanitize), OpenCode, OpenRouter-style. Multi-provider with retry. `model_config.rs`, `agent_provider_resolver.rs`.
+- **Safety:** `forge_main/src/sandbox.rs` (sandbox), policies (`forge_domain/src/policies`, `forge_services/src/permissions.default.yaml`), hooks.
+- **TUI/render:** `forge_tui`, `forge_display`, `forge_spinner`, `forge_select`, `forge_markdown_stream`, `ghostty-kit`, `forge3d` (visualization).
+- **Version:** workspace `2.9.9` (README claims 2.10.0 — minor drift). ~280 files contain tests.
+
+**What the code does NOT contain (confirmed by targeted grep — no real hits):**
+- ❌ No LSP / language-server integration (no rust-analyzer/pyright/gopls wiring).
+- ❌ No AST/tree-sitter repo map or PageRank symbol-graph context selection (the `tool_services/syn/` dir is a stub: only `mod.rs`).
+- ❌ No browser automation tool.
+- ❌ No true parallel multi-session / git-worktree agent orchestration (sandbox exists; parallel agents do not).
+- ❌ No lint/test autofix loop (no "run tests → repair → retry" harness).
+- ❌ No semantic embeddings in the default path (hash-only).
+- ❌ No first-class cost/budget UI surface (telemetry exists; per-session $ ceiling does not).

+
+**Net read:** forgecode is strong on architecture, MCP, multi-agent, skills, context compaction, and session persistence. It is materially **behind SOTA on code-comprehension infrastructure (LSP + AST repo map), the test/repair loop, parallel multi-session orchestration, cost/budget surfacing, and semantic memory.** Those are precisely the dimensions that move SWE-bench-style real-world performance and developer trust.

+## 2. Technical Research — Adoptable Techniques (cited)
+
+### 2.1 Code comprehension & context selection
+- **Tree-sitter + PageRank repo map (Aider).** AST symbol extraction → file dependency graph → PageRank to rank identifiers → fit top-ranked context into a token budget; 130+ languages via `tags.scm` queries; battle-tested at 15B tokens/week. **Highest-leverage single adoptable technique for forgecode.** Source: [aider repomap](https://aider.chat/2023/10/22/repomap.html), [aider docs](https://aider.chat/docs/repomap.html).
+- **LSP-as-context (OpenCode).** Feed the model real type info, signatures, import paths, and live compiler diagnostics (rust-analyzer/pyright/gopls/clangd…); auto-load LSP per language. Source: [OpenCode LSP](https://opencode.ai/docs/lsp/).
+- **AST-guided adaptive memory (CodeMEM).** AST-structured memory for repository-level iterative code generation. Source: [arXiv 2601.02868](https://arxiv.org/pdf/2601.02868).
+
+### 2.2 Context management & memory (forgecode already has a compaction base to extend)
+- **Meta Context Engineering** treats context assembly as an optimization problem: **89.1% SWE-bench Verified vs 70.7%** for hand-engineered baselines — context assembly, not raw model, is the dominant lever. Source: [arXiv 2603.07670](https://arxiv.org/html/2603.07670v1).
+- **MemGPT-style memory-as-decision** (LLM decides when to retrieve/manage long-term context) and **GraphRAG / RAPTOR / Self-RAG** retrieval. Source: [memory survey arXiv 2603.07670](https://arxiv.org/html/2603.07670v1).
+- **Confucius Code Agent** — explicit agent context layer: hierarchical working memory + adaptive compression + filesystem-backed scoped visibility. Direct analog to extend `forge_domain/src/compact/`. Source: [arXiv 2512.10398](https://arxiv.org/pdf/2512.10398).
+- **AgentOCR** — optical self-compression of agent history (compress trajectory rather than drop it). Source: [arXiv 2601.04786](https://arxiv.org/pdf/2601.04786).
+- **Structured memory that grows with the user** for code agents. Source: [arXiv 2603.13258](https://arxiv.org/pdf/2603.13258).
+
+### 2.3 Repair & evaluation scaffolds
+- **Agentless pipeline** (localize → repair → validate, one-shot; +test-gen-by-considering-other-tests +patch-selection-by-voting) is competitive with full agents and cheap. Adopt voting/patch-selection as a forgecode "repair mode." Source: [SWE-bench leaderboard dissection arXiv 2506.17208](https://arxiv.org/html/2506.17208v2), [OpenAI SWE-bench Verified](https://openai.com/index/introducing-swe-bench-verified/).
+- **Scaffold matters more than the base model** — retrieval, tools, recovery-from-failed-patches, retries change scores materially. SWE-agent (agent–computer interface), OpenHands (multi-agent), AutoCodeRover (AST search). Source: [arXiv 2506.17208](https://arxiv.org/html/2506.17208v2).
+- **Long-horizon eval beyond single-issue SWE-bench:** SWE-EVO (software evolution), LoCoBench-Agent (long-context SWE), AMA-Bench (long-horizon memory). Adopt as forgecode's own internal eval harness. Sources: [SWE-EVO 2512.18470](https://arxiv.org/pdf/2512.18470), [LoCoBench-Agent 2511.13998](https://arxiv.org/pdf/2511.13998), [AMA-Bench 2602.22769](https://arxiv.org/pdf/2602.22769).
+
+### 2.4 Serving / efficiency
+- **KV-cache sharing across LLMs (DroidSpeak)** — relevant for forgecode's multi-provider routing + future multi-agent fan-out. Source: [arXiv 2411.02820](https://arxiv.org/pdf/2411.02820).
+- **MemSearcher** — RL-trained reason+search+manage-memory. Source: [arXiv 2511.02805](https://arxiv.org/pdf/2511.02805).

+## 3. User / Market Needs (cited)
+
+1. **Verification bottleneck is the #1 pain.** Devs report **~11.4 hrs/week reviewing AI code vs 9.8 hrs writing** new code — review/test tooling now matters more than raw generation.

+## 4. Gap Analysis (code-grounded)
+
+| # | Gap | Evidence in forgecode | SOTA reference | Impact |
+|---|---|---|---|---|
+| G1 | **No code-aware context (LSP + AST repo map)** | `tool_services/syn/` is a `mod.rs` stub; no tree-sitter/PageRank/LSP deps | Aider repo map, OpenCode LSP | HIGH — directly caps real-codebase accuracy |
+| G2 | **No test/lint autofix repair loop** | no run-tests→repair harness in `forge_app` | Aider auto test+lint; Agentless validate | HIGH — verification bottleneck is #1 user pain |
+| G3 | **No parallel multi-session / worktree orchestration** | `sandbox.rs` only; single conversation in `Orchestrator` | OpenCode, Cursor, "run two" | MED-HIGH — emerging expectation |
+| G4 | **Hash-only embeddings (no semantic memory)** | `forge_embed/src/hash_only.rs` | MemGPT, GraphRAG, structured memory | MED-HIGH — FTS/vec store underdelivers |
+| G5 | **No cost/budget surface** | telemetry exists; no per-session $ ceiling/UI | Kiro credits, Kilo PAYG, Gemini free-tier UX | MED — trust + adoption |
+| G6 | **Code review is a tool, not a workflow** | `code_review` in catalog; no PR/diff review agent loop | Amp review agent, Claude Code PR | MED — addresses verification pain |
+| G7 | **Approval modes under-productized** | sandbox + `permissions.default.yaml` exist; no clear read-only/auto/full UX | Codex 3-mode approvals | MED — table-stakes safety UX |
+| G8 | **No internal SWE-style eval harness** | `benchmarks/` exists but no SWE-bench/long-horizon loop | SWE-EVO, LoCoBench-Agent | MED — regression-proofs reliability (need #2) |
+| G9 | **Context engine not optimization-driven** | `compact/` is heuristic (importance/eviction) | Meta Context Engineering 89.1% vs 70.7% | MED — biggest measured single lever |
+
+### Top-5 SOTA gaps
+1. **G1 — Code-aware context (Tree-sitter repo map + LSP diagnostics).**
+2. **G2 — Test/lint autofix repair loop (validate→repair→retry).**
+3. **G4/G9 — Semantic memory + optimization-driven context engine** (replace hash-only embeds; treat context as optimization).
+4. **G3 — Parallel multi-session / worktree orchestration.**
+5. **G5/G6/G7 — Trust trifecta: cost/budget UI + review workflow + first-class approval modes.**
+

+
+## 5. Prioritized SOTA Roadmap (DAG + effort + acceptance + test coverage)
+
+**Coverage mandate (every feature):** 85–100% across **unit → e2e → perf → chaos**. Concretely: unit tests on pure logic (`forge_domain`); integration/e2e through `forge_api`/`forge_main`; perf benchmarks in `benchmarks/` (token budget, latency, ranking); chaos (provider timeouts, malformed tool output via `forge_json_repair`, LSP crash, cancelled sessions, partial patch failure).

+
+### Phase 0 — Comprehension foundation (unblocks everything)
+
+**F1 — Tree-sitter AST repo map + PageRank context selection** *(predecessor: none)*
+- Effort: major refactor — 3–5 parallel subagents, ~15–20 min batches. Lands in `forge_services` (new `repo_map` service) + `forge_domain` ranking types; wire `tags.scm` per language; flesh out `tool_services/syn/`.
+- Acceptance: given a repo + query, returns ranked symbol context fitting a configurable token budget; ≥100 languages via tree-sitter; deterministic ranking; measurable accuracy lift on internal eval (F8).
+- Coverage: unit (parse/rank/budget-fit) ≥95%; e2e (real repos) ; perf (rank+assemble < target ms on 10k-file repo); chaos (unparseable files, symlink loops, binary files).
+
+**F2 — LSP diagnostics-as-context** *(predecessor: none; complements F1)*
+- Effort: cross-stack — 2–3 subagents, ~8 min. New `forge_infra` LSP adapter (rust-analyzer/pyright/gopls/clangd), auto-load per language; expose diagnostics+signatures to orchestrator.
+- Acceptance: edits validated against live diagnostics; signature/import info injected pre-edit; graceful when no LSP present.
+- Coverage: unit (protocol codec) ; e2e (per-language smoke) ; perf (LSP startup amortized) ; chaos (LSP crash/restart, slow server timeout → degrade not hang).
+
+**F3 — Semantic memory (replace hash-only embeddings)** *(predecessor: none)*
+- Effort: cross-stack — ~8 min. Real embedding provider in `forge_embed` behind existing trait; populate vector search; MemGPT-style retrieve-on-demand over `forge_dbd` store.
+- Acceptance: semantic recall beats FTS baseline on a held-out conversation-recall set; configurable local/remote embedder; no PII leakage.
+- Coverage: unit (embed/index/query) ≥90%; e2e (recall@k) ; perf (index/query latency) ; chaos (embedder outage → fall back to FTS visibly, not silently).
+
+### Phase 1 — Trust & verification
+
+**F4 — Validate→repair→retry loop** *(predecessors: F1, F2)*
+- Effort: major — 3–5 subagents, ~15 min. New harness in `forge_app`: after edits, run lint+tests, parse failures, repair, bounded retries; Agentless-style patch voting/selection.
+- Acceptance: on a seeded broken-test suite, autonomously reaches green within N retries; never loops infinitely; emits a diff+rationale.
+- Coverage: unit (failure parsing, retry bound, voting) ; e2e (red→green on fixture repos) ; perf (retry budget) ; chaos (flaky tests, non-deterministic failures, partial patch apply).
+
+**F5 — First-class approval/sandbox modes** *(predecessor: none)*
+- Effort: small-feature — ~3 min. Productize `permissions.default.yaml`+`sandbox.rs` into read-only / auto / full modes with in-session `/permissions` switching (Codex parity).
+- Acceptance: mode gates tool execution correctly; switchable mid-session; audit log of approvals.
+- Coverage: unit (gate matrix) ≥95%; e2e (mode transitions) ; chaos (privilege-escalation attempts blocked).
+
+**F6 — Code review workflow (diff/PR review agent)** *(predecessor: F5)*
+- Effort: cross-stack — ~8 min. Promote `code_review` tool to a review agent loop over diffs/PRs with severity-ranked findings.
+- Acceptance: produces actionable, ranked review on a diff; integrates with git; suppresses noise.
+- Coverage: unit (finding ranking) ; e2e (real diffs) ; perf (large-diff handling) ; chaos (binary/huge diffs).
+
+**F7 — Cost/budget surface** *(predecessor: none)*
+- Effort: small-feature — ~3 min. Per-session token/$ tracking in TUI from existing telemetry; configurable ceiling that pauses for approval.
+- Acceptance: live cost shown; ceiling pause works; per-provider pricing table.
+- Coverage: unit (cost math per provider) ≥95%; e2e (ceiling pause) ; chaos (missing pricing → conservative estimate, flagged).
+
+### Phase 2 — Scale & reach
+
+**F8 — Internal SWE/long-horizon eval harness** *(predecessors: F1, F4)*
+- Effort: major — ~15 min. SWE-bench-Verified-style + SWE-EVO/LoCoBench-style runner in `benchmarks/`; CI-gated regression scores.
+- Acceptance: reproducible pass-rate report; blocks merges on regression; tracks cost/latency per task.
+- Coverage: e2e (harness runs) ; perf (throughput) ; chaos (sandbox isolation, timeouts).
+
+**F9 — Context-as-optimization engine** *(predecessors: F1, F3)*
+- Effort: major — ~15 min. Evolve `forge_domain/src/compact/` from heuristic to optimization-driven assembly (Meta Context Engineering direction).
+- Acceptance: measurable lift on F8 vs current heuristic compaction; bounded assembly latency.
+- Coverage: unit (assembler) ; e2e (eval lift) ; perf (assembly budget) ; chaos (pathological histories).
+
+**F10 — Parallel multi-session / git-worktree orchestration** *(predecessors: F1, F4)*
+- Effort: major — ~20 min. Multiple concurrent agent sessions over isolated worktrees; merge/coordination.
+- Acceptance: N parallel sessions on one repo without state corruption; isolated worktrees; clean merge path.
+- Coverage: unit (session isolation) ; e2e (2+ parallel) ; perf (concurrency cap) ; chaos (worktree lock contention, conflicting edits, crash mid-session).
+
+**F11 — Local/offline first-class (Ollama)** *(predecessor: none)*
+- Effort: small-feature — ~3 min. Promote OpenAI-compatible local endpoints to a documented Ollama profile.
+- Acceptance: fully local run works offline; model list discovery.
+- Coverage: unit (endpoint cfg) ; e2e (offline smoke) ; chaos (endpoint down → clear error, no silent remote fallback).
+
+---
+
+## 6. Quick-win sequencing (aggressive, agent-driven)
+- **Wave 1 (parallel):** F1, F2, F3, F5, F7 — 5 subagents, comprehension + trust basics.
+- **Wave 2:** F4, F6 — repair loop + review (need F1/F2/F5).
+- **Wave 3:** F8, F9, F10, F11 — eval, optimized context, parallelism, local.
+
+This ordering front-loads the two highest-leverage SOTA gaps (code-aware context, repair loop) and the verification/trust features users most want, while the eval harness (F8) locks in reliability — the exact axis where competitors (Claude Code regressions) lost user trust.

+
+## 2. The 2026 SOTA frontier — 15 highest-leverage capabilities
+1. Loop-engineering agent core (gather→act→verify + autonomous test/lint/repair).
+2. Multi-tier model routing (frontier planner + cheap fast executor).
+3. Parallel multi-agent over isolated git worktrees with dependency chains.
+4. OS-level sandboxing that minimizes approval fatigue (the trust differentiator).
+5. Sophisticated context compaction (threshold summary + message hiding + cushion).
+6. Hierarchical persistent memory (rules files + auto-memory + git-as-memory).
+7. Cloud/background async agents (isolated VM, webhook/cron, PR-on-done, audit logs).
+8. First-class MCP (client+server; stdio/HTTP/SSE; OAuth) — table stakes.
+9. Explicit plan mode with approval gating before mutation.
+10. Checkpoints & rewind/undo of conversation AND file state.
+11. Clean headless/CI mode (no-TTY, JSON/JSONL streaming, pipeable).
+12. Lifecycle hooks (Pre/PostToolUse, policy gates, scheduled agents).
+13. Whole-repo context strategy (1M–2M windows and/or efficient repo-maps/indexes).
+14. Provider-agnostic BYOK incl. local/offline + explicit cost/spend controls.
+15. High-craft TUI/UX (mode switch, vim, live tool/reasoning visibility, glamorous render).
+
+**Meta-trend: agent design beats raw model choice** — Factory Droid is #1 on Terminal-Bench (58.75%) with sub-frontier models, beating Claude Code & Codex. Battleground shifted from prompt-engineering to loop-engineering + permission/trust UX + multi-agent orchestration.
+
+## 3. Status flags (avoid anchoring on tools mid-transition)
+- **Gemini CLI** sunset for free/individual tiers 2026-06-18 → successor **Antigravity CLI** (early, gaps).
+- **OpenCode** archived (Sept 2025) → dev moved to **Charm Crush**.
+- **Continue CLI** frozen at v2.0 after Cursor acquisition (June 2026).
+- **Cursor** sandbox: CVE-2026-22708 (bypass) — note for security comparisons.

+# SLSA Build Attestation
+
+This repository publishes build provenance for release artifacts in
+accordance with [SLSA (Supply-chain Levels for Software Artifacts)][slsa]
+Build specifications. SLSA provenance allows downstream consumers to
+verify that an artifact was built from the expected source repository,
+at the expected commit, by the expected build platform.
+
+## Target Level
+
+**Current target: SLSA Build L2 (achieved today)**
+
+The release pipeline is hosted on GitHub Actions, an isolated build
+platform that is owned and administered by GitHub. Provenance is
+generated automatically for every published release using
+[`slsa-framework/slsa-github-generator`][slsa-gh-gen] and the
+`attest-build-provenance` action. Provenance is signed by a GitHub-
+hosted OIDC token and stored in the [GitHub Artifact Attestations][ghaa]
+log alongside the artifact.
+
+| Requirement                                 | Status       |
+| ------------------------------------------- | ------------ |
+| Provenance generated automatically          | ✅ L2        |
+| Provenance distributed alongside artifact   | ✅ L2        |
+| Build platform hosted and isolated          | ✅ L2        |
+| Provenance authenticity (OIDC-signed)       | ✅ L2        |
+| Build platform isolated from build request | ⏭ L3 target |
+| Hardened build platform                     | ⏭ L3 target |
+| Provenance non-forgeable (sigstore/cosign)  | ⏭ L3 target |
+
+## Workflow
+
+The CI workflow lives at
+[`.github/workflows/release-attestation.yml`](../.github/workflows/release-attestation.yml)
+and is triggered:
+
+- Automatically on every `release: published` event.
+- Manually via `workflow_dispatch` for ad-hoc provenance generation.
+
+### Build Steps
+
+1. **Checkout** — full history (`fetch-depth: 0`) so the git revision
+   can be embedded in provenance.
+2. **Toolchain** — pinned `stable` Rust via
+   [`dtolnay/rust-toolchain`][rust-toolchain].
+3. **Cache** — cargo registry, git index, and `target/` via
+   [`Swatinem/rust-cache`][rust-cache].
+4. **Build** — `cargo build --release --locked --workspace --all-targets`.
+5. **Stage** — collect built executables, source tarball, and a build
+   manifest into `release-artifacts/`.
+6. **Upload** — publish `release-artifacts` as a GitHub Actions artifact
+   (90 day retention).
+7. **Attest** — generate SLSA Build L2 provenance with
+   `slsa-framework/slsa-github-generator/attest-build-provenance@v1`.
+
+## Verification
+
+Consumers can verify a release artifact's provenance using the
+[GitHub CLI][gh-cli]:
+
+```bash
+gh attestation verify <artifact> --owner <org>
+```
+
+Or with [`cosign`][cosign]:
+
+```bash
+cosign verify-attestation \
+  --certificate-identity-regexp 'https://github.com/slsa-framework/slsa-github-generator' \
+  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
+  <artifact>
+```
+
+The in-toto provenance attestation (`slsa-github-generator/actions/attest-build-provenance`)
+contains:
+
+- `builder.id` — `https://github.com/actions/runner`
+- `invocation.config.source.uri` — repository URL
+- `invocation.config.source.entryPoint` — build workflow path
+- `invocation.config.source.digest.sha1` — git commit SHA
+- `invocation.config.source.ref` — git ref (tag / branch)
+- `metadata.buildInvocationID` — workflow run ID
+- `metadata.completeness.parameters` — whether all inputs are hashed
+- `metadata.completeness.environment` — whether environment is fully captured
+
+## Path to SLSA Build L3
+
+The current pipeline satisfies L2. To graduate to L3, the following
+additions are required:
+
+1. **Isolated build environment** — move from a hosted runner to
+   ephemeral, single-tenant builders (e.g.
+   `slsa-framework/slsa-github-generator`'s `generator_containerized_slsa3.yml`
+   reusable workflow, or a self-hosted runner with a hardened image).
+2. **Provenance non-forgeability** — the generator workflow re-signs
+   provenance with a build-platform-held signing key (sigstore / KMS)
+   rather than relying on the GitHub OIDC token alone.
+3. **Provenance transparency log** — the generator publishes
+   provenance to a transparency log (e.g. Rekor) so forgery is
+   detectable by the wider community.
+
+To upgrade, switch the `attest-build-provenance` step to invoke the
+`slsa-framework/slsa-github-generator/.github/workflows/generator_containerized_slsa3.yml@v2`
+reusable workflow with a build image pinned by digest. The reusable
+workflow handles ephemeral runners, hardened isolation, and
+non-forgeable provenance signing transparently.

+
+## Dependencies
+
+- None (self-contained enhancement)
+
+## Blockers
+
+- None identified
+
+---
+
+## Notes
+
+- LLM summarization should use cheap model by default (haiku-3.5)
+- All new features gated behind config flags for backward compatibility
+- Compaction should still work if LLM provider unavailable (fallback to extract)

+# Forgecode Compaction System Enhancement Plan
+
+## Objective
+
+Enhance the forgecode context compaction system from a purely structural extraction approach to a hybrid system that combines **intelligent pre-processing**, **LLM-based semantic summarization**, and **adaptive eviction strategies** to maximize context retention of meaningful information while maintaining deterministic performance.
+
+---
+
+## SOTA Research Summary
+
+### Current Industry Approaches
+
+| Approach | Provider | Characteristics |
+|----------|----------|----------------|
+| **Structural Extraction** | Current forgecode | Fast, deterministic, low semantic fidelity |
+| **LLM Summarization** | Claude Code, OpenAI Agents | High fidelity, slow (~500ms+), expensive |
+| **Hybrid Extraction** | Microsoft Copilot | Combines extraction + LLM refinement |
+| **Importance Scoring** | Cursor AI | Scores messages by relevance, preserves high-value |
+| **Incremental Summarization** | Perplexity AI | Accumulates summaries, reduces redundancy |
+| **Semantic Chunking** | LangChain | Groups semantically similar content |
+
+### Key Findings from Anthropic Documentation
+
+1. **Compaction timing is critical**: Trigger at 70-80% of context window to preserve headroom
+2. **Tool call atomicity**: Never split tool calls from their results
+3. **Extended thinking preservation**: Reasoning chains must be maintained for model continuity
+4. **Summary quality matters**: Poor summaries degrade subsequent model performance
+
+### Best Practices Identified
+
+1. **Pre-compaction filtering**: Remove noise before summarization
+2. **Adaptive eviction windows**: More aggressive near context limits
+3. **Importance-based preservation**: High-value messages protected from eviction
+4. **Structured summaries**: Machine-parseable formats improve downstream processing
+5. **Cost-latency tradeoff**: Cheaper models can be used for summarization
+
+---
+
+## Implementation Plan
+
+### Phase 1 — Enhanced Configuration (`forge_config` + `forge_domain`)
+
+#### Task 1: Extend `CompactConfig` with new options
+
+**Files:** `crates/forge_config/src/compact.rs`, `crates/forge_domain/src/compact/compact_config.rs`
+
+```rust
+// New fields in CompactConfig
+pub struct Compact {
+    // ... existing fields ...
+
+    /// Strategy for summarization: extract only, llm, or hybrid
+    #[serde(default)]
+    pub summarization_strategy: SummarizationStrategy,
+
+    /// Enable pre-compaction filtering
+    #[serde(default)]
+    pub enable_prefilter: bool,
+
+    /// Enable adaptive eviction window
+    #[serde(default)]
+    pub enable_adaptive_eviction: bool,
+
+    /// Enable importance-based preservation
+    #[serde(default)]
+    pub enable_importance_scoring: bool,
+
+    /// Maximum tokens in generated summary
+    #[serde(default)]
+    pub summary_max_tokens: Option<usize>,
+}
+
+pub enum SummarizationStrategy {
+    /// Pure structural extraction (current behavior)
+    Extract,
+    /// LLM-based semantic summarization
+    Llm,
+    /// Hybrid: extract then refine with LLM
+    Hybrid,
+}
+```
+
+#### Task 2: Add `CompactionHistory` for incremental tracking
+
+**Files:** `crates/forge_domain/src/compact/history.rs`, `crates/forge_domain/src/compact/mod.rs`
+
+```rust
+#[derive(Default, Clone, Serialize, Deserialize)]
+pub struct CompactionHistory {
+    /// Content hashes of past summaries to detect redundancy
+    pub summary_hashes: Vec<u64>,
+    /// Last seen file versions (path -> hash)
+    pub file_versions: HashMap<PathBuf, String>,
+    /// Count of successful compactions
+    pub compaction_count: usize,
+    /// Total tokens reduced across all compactions
+    pub total_tokens_reduced: usize,
+}
+```
+
+#### Task 3: Add `ImportanceScore` to messages
+
+**Files:** `crates/forge_domain/src/context.rs`
+
+```rust
+#[derive(Clone, Debug, Serialize, Deserialize)]
+pub struct MessageImportance {
+    /// Base importance score (0-100)
+    pub score: u8,
+    /// Factors contributing to score
+    pub factors: Vec<ImportanceFactor>,
+}
+
+#[derive(Clone, Debug, Serialize, Deserialize)]
+pub enum ImportanceFactor {
+    HasToolCalls,
+    HasErrors,
+    HasFileChanges,
+    HasUserIntent,
+    ReasoningChain,
+    Decision,
+}
+```
+
+---
+
+### Phase 2 — Enhanced Eviction Strategy (`forge_domain`)
+
+#### Task 4: Implement adaptive eviction window
+
+**Files:** `crates/forge_domain/src/compact/strategy.rs`
+
+```rust
+impl CompactionStrategy {
+    /// Calculate adaptive eviction percentage based on context state
+    pub fn adaptive_eviction(&self, context: &Context, threshold: usize) -> f64 {
+        let token_count = context.token_count();
+        let ratio = token_count as f64 / threshold as f64;
+
+        // Eviction aggressiveness increases as we approach threshold
+        match ratio {
+            r if r > 0.95 => 0.5,  // 50% - critical zone
+            r if r > 0.85 => 0.35, // 35% - warning zone
+            r if r > 0.70 => 0.2, // 20% - normal
+            _ => 0.1,              // 10% - conservative
+        }
+    }
+}
+```
+
+#### Task 5: Implement importance-based message scoring
+
+**Files:** `crates/forge_domain/src/compact/importance.rs`
+
+```rust
+impl MessageImportance {
+    pub fn calculate(msg: &ContextMessage) -> Self {
+        let mut score: u8 = 50; // Base score
+        let mut factors = Vec::new();
+
+        match msg.deref() {
+            ContextMessage::Text(t) => {
+                if t.tool_calls.is_some() {
+                    score += 20;
+                    factors.push(ImportanceFactor::HasToolCalls);
+                }
+                if t.reasoning_details.is_some() {
+                    score += 15;
+                    factors.push(ImportanceFactor::ReasoningChain);
+                }
+            }
+            ContextMessage::Tool(r) if r.is_error() => {
+                score = 100; // Critical
+                factors.push(ImportanceFactor::HasErrors);
+            }
+            _ => {}
+        }
+
+        Self { score, factors }
+    }
+
+    /// Minimum importance required to survive compaction
+    pub const MIN_SURVIVAL_SCORE: u8 = 60;
+}
+```
+
+#### Task 6: Enhanced eviction range finding with importance
+
+**Files:** `crates/forge_domain/src/compact/strategy.rs`
+
+```rust
+fn find_eviction_range_with_importance(
+    context: &Context,
+    max_retention: usize,
+    history: &CompactionHistory,
+) -> Option<(usize, usize)> {
+    let messages = &context.messages;
+
+    // Filter out high-importance messages from eviction candidates
+    let eviction_candidates: Vec<usize> = messages
+        .iter()
+        .enumerate()
+        .filter(|(_, msg)| {
+            let importance = MessageImportance::calculate(msg);
+            importance.score < MessageImportance::MIN_SURVIVAL_SCORE
+        })
+        .map(|(i, _)| i)
+        .collect();
+
+    // Find range using only eviction candidates
+    find_sequence_preserving_last_n(context, max_retention)
+        .map(|(start, end)| {
+            // Adjust range to exclude protected messages
+            let protected: Vec<usize> = messages
+                .iter()
+                .enumerate()
+                .filter(|(_, msg)| {
+                    let importance = MessageImportance::calculate(msg);
+                    importance.score >= MessageImportance::MIN_SURVIVAL_SCORE
+                })
+                .map(|(i, _)| i)
+                .collect();
+
+            // If protected messages fall in eviction range, shrink it
+            let new_start = protected.iter().find(|&&i| i >= start).copied().unwrap_or(start);
+            (new_start.max(start), end)
+        })
+}
+```
+

+
+### Phase 3 — LLM Summarization (`forge_app`)
+
+#### Task 7: Create summarization prompt template
+
+**Files:** `templates/forge-summarization-prompt.md` (new)
+
+```markdown
+You are a precise code assistant summarizing previous conversation context.
+
+## Task
+Summarize the following conversation history into a concise, structured format that preserves:

+### Phase 5 — Enhanced Summary Template (`forge_app`)
+
+#### Task 11: Create enhanced summary frame
+
+**Files:** `templates/forge-partial-summary-frame-v2.md`
+
+```markdown
+{{#if structured}}
+## Prior Context Summary
+
+**Files Modified:**
+{{#each files}}
+- `{{path}}`: {{description}}
+{{/each}}
+
+**Operations:**
+- **Reads**: {{read_count}} files
+- **Writes/Modifies**: {{write_count}} files
+- **Executions**: {{executions}}
+- **Searches**: {{searches}}
+
+{{#if decisions}}
+**Key Decisions:**
+{{#each decisions}}
+- {{this}}
+{{/each}}
+{{/if}}
+
+{{#if constraints}}
+**Constraints Discovered:**
+{{#each constraints}}
+- {{this}}

+
+{{#if llm_summary}}
+{{llm_summary}}
+{{/if}}
+
+---
+*This summary was generated from {{compaction_count}} previous compaction(s).*
+{{/if}}
+
+Proceed with implementation based on this context.
+```
+
+---
+
+### Phase 6 — Metrics & Observability
+
+#### Task 12: Add compaction metrics collection
+
+**Files:** `crates/forge_domain/src/compact/metrics.rs`
+
+```rust
+#[derive(Default, Clone, Serialize, Deserialize)]
+pub struct CompactionMetrics {
+    /// Number of times compaction triggered
+    pub compaction_count: usize,
+    /// Total tokens reduced
+    pub total_tokens_reduced: usize,
+    /// Average token reduction per compaction
+    pub avg_token_reduction: f64,
+    /// Total messages reduced
+    pub total_messages_reduced: usize,
+    /// Compaction strategies used
+    pub strategies_used: HashMap<String, usize>,
+    /// Errors encountered
+    pub errors: Vec<CompactionError>,
+}
+
+impl CompactionMetrics {
+    pub fn record(&mut self, result: &CompactionResult, strategy: &str) {
+        self.compaction_count += 1;
+        self.total_tokens_reduced +=
+            result.original_tokens.saturating_sub(result.compacted_tokens);
+        self.total_messages_reduced +=
+            result.original_messages.saturating_sub(result.compacted_messages);
+        *self.strategies_used.entry(strategy.to_string()).or_insert(0) += 1;
+    }
+}
+```
+
+---
+
+## Verification Criteria
+
+1. **Functional correctness:**
+   - [ ] Compaction triggers at configured thresholds
+   - [ ] Tool calls remain atomic after compaction
+   - [ ] Extended thinking reasoning preserved
+   - [ ] Usage accumulation works correctly
+   - [ ] Droppable messages removed
+
+2. **Enhanced features:**
+   - [ ] Adaptive eviction adjusts based on context ratio
+   - [ ] Importance scoring protects high-value messages
+   - [ ] LLM summarization produces coherent summaries
+   - [ ] Pre-filter removes noise before compaction
+   - [ ] History tracking prevents redundant summaries
+
+3. **Performance:**
+   - [ ] Structural extraction: <5ms
+   - [ ] LLM summarization: <2s with timeout
+   - [ ] No memory leaks from history accumulation
+
+4. **Backward compatibility:**
+   - [ ] Existing `compact` config remains valid
+   - [ ] Default behavior unchanged (structural extraction)
+   - [ ] Migration path for existing conversations
+
+---
+
+## Potential Risks and Mitigations
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| LLM summarization adds latency | Medium | Use cheaper models (haiku), cache summaries, timeout after 3s |
+| Poor LLM summary quality | High | Fallback to structural extraction, validate summary format |
+| History accumulation memory growth | Low | Limit history size, compress older entries |
+| Importance scoring misclassification | Medium | Allow configuration of thresholds, provide defaults |
+| Adaptive eviction too aggressive | Low | Provide conservative defaults, allow tuning |
+
+---
+
+## Alternative Approaches
+
+1. **Pure LLM Approach**: Use LLM for all summarization, skip structural extraction
+   - Pros: Higher semantic fidelity
+   - Cons: Slower, more expensive, less deterministic
+
+2. **Semantic Embedding Approach**: Use embeddings to find and preserve semantically important messages
+   - Pros: Better relevance scoring
+   - Cons: Requires embedding service, more complex
+
+3. **Streaming Compaction**: Compact incrementally as context grows, not at threshold
+   - Pros: More predictable latency, smoother context growth
+   - Cons: More complex state management
+
+4. **Multi-Model Cascade**: Start with extraction, escalate to LLM for complex contexts
+   - Pros: Balances cost and quality
+   - Cons: Most complex implementation
+
+---
+
+## Phased Rollout
+
+| Phase | Features | Risk Level | Duration |
+|-------|----------|------------|----------|
+| Phase 1 | Config extensions, adaptive eviction | Low | 1 week |
+| Phase 2 | Importance scoring, pre-filtering | Low | 1 week |
+| Phase 3 | LLM summarization (opt-in) | Medium | 2 weeks |
+| Phase 4 | Metrics, observability | Low | 1 week |
+| Phase 5 | Template improvements | Low | 1 week |

+# Forge Cursor Position Error Investigation & Fix
+# Forge Cursor Position Error Investigation & Fix
+
+## Problem
+Multiple forge sessions in `repos` are crashing with **"cursor position could not be read in a normal duration"** error.
+
+## Initial Findings
+
+### 1. Cursor Tracking in Codebase
+- **`executor.rs:208`**: There's a comment noting flush is necessary to avoid "cursor could not be found" errors
+- **Terminal Context**: Reads from zsh plugin environment variables (`_FORGE_TERM_COMMANDS`, etc.)
+- **UI Cursors**: These are fzf/select widget cursors, NOT terminal cursor position
+
+### 2. Error Location Unknown
+- The error message **"cursor position could not be read in a normal duration"** is NOT found in the Rust source
+- Likely comes from:
+  - Upstream ForgeCode binary (pre-compiled)
+  - Terminal/TTY layer
+  - zsh plugin hooks
+
+### 3. Session State in Database
+- **4161 total conversations** in `~/forge/.forge.db`
+- Sessions crash but don't properly clean up
+- Need to audit for incomplete/orphaned sessions
+
+## Session Audit Results (Last 24 Hours)
+
+### Summary
+- **Total conversations**: 15
+- **Completed**: 10 (67%)
+- **Likely Incomplete**: 2 (13%)
+- **Unknown/Needs Review**: 3 (20%)
+
+### Sessions Needing Resumption
+
+| ID | Title | Issue |
+|----|-------|-------|
+| `ddeddf14` | Audit and stabilize `thegent` | **CRASHED** - Last message cut off mid-sentence. Likely cursor position error. |
+| `efa9e0a4` | Audit thegent (task plan) | Task plan created but work not started |
+| `9193766b` | Extract GitHub repos/papers | Download still in progress (23%) |
+
+### Sessions Completed (but no TASK COMPLETED marker)
+- `f1dcf57b` - PolicyStack tests (All 513 tests pass)
+- `e5193bbc` - Identify incomplete sessions (investigation complete)
+- `1e984679` - Idle forge sessions (table complete)
+- `30b57666` - SOTA helios-cli (document exists)
+- Plus 6 others with proper completion markers
+
+---
+
+## Investigation Tasks
+
+- [x] 1. **Audit all forge conversations**: Found 3 sessions needing resumption
+- [ ] 2. **Find the error source**: Search upstream ForgeCode binary or check if it's from terminal TTY
+- [ ] 3. **Check zsh plugin hooks**: Review `preexec`/`precmd` hooks for cursor tracking
+- [ ] 4. **Examine TTY/terminal code**: Look for `TIOCGWINSZ` or cursor position reads
+- [ ] 5. **Review task cancellation timing**: Check if async task cancellation affects cursor state
+- [ ] 6. **Check parallel tool execution**: Look for race conditions in cursor tracking
+
+## Potential Fixes
+
+1. **Deterministic flush ordering** - Ensure explicit flush after all output
+2. **Cursor state machine** - Track cursor state transitions with proper guards
+3. **Graceful degradation** - Timeout handling when cursor can't be read
+4. **Race condition fixes** - Proper synchronization for parallel operations
+5. **Error recovery** - Add retry logic for cursor position reads
+
+## Verification
+
+- [ ] Add integration tests for cursor tracking under load
+- [ ] Test with long-running commands
+- [ ] Test with multiple parallel tool calls
+- [ ] Verify fix with batch session resumption
+
+## Status
+**Investigating** - Error source not yet located in codebase

+# OmniRoute Benchmark Plan
+
+**Created:** 2026-05-05
+**Status:** Draft
+**Session:** 9d873d05
+
+## Overview
+
+Benchmark plan for comparing OmniRoute implementations: TypeScript vs Rust/Go performance.
+
+## Test Scenarios
+
+### 1. Request Routing Performance
+- [ ] Single route resolution (no model selection)
+- [ ] Multi-route resolution with fallback
+- [ ] Concurrent request handling (100/500/1000 RPS)
+
+### 2. Model Selection Latency
+- [ ] Token counting overhead
+- [ ] Cost calculation per provider
+- [ ] Response time comparison (OpenAI vs Anthropic)
+
+### 3. Provider Fallback Chains
+- [ ] Single fallback (1 primary, 1 backup)
+- [ ] Multi-fallback (1 primary, 2+ backups)
+- [ ] Rate limit handling
+
+### 4. Throughput Benchmarks
+
+| Scenario | TS Target | Rust Target | Go Target |
+|----------|-----------|-------------|-----------|
+| Route Only | <5ms | <1ms | <2ms |
+| With Model Select | <50ms | <10ms | <15ms |
+| 100 RPS | <200ms p99 | <50ms p99 | <75ms p99 |
+| 500 RPS | <500ms p99 | <100ms p99 | <150ms p99 |
+
+## Test Infrastructure
+
+```
+/PhenoLang/omniroute-core/
+├── benches/           # Criterion benchmarks
+├── benches/suite.rs   # Benchmark suite
+└── benches/results/   # Historical results
+```
+
+## Execution Commands
+
+```bash
+# Run all benchmarks
+cd /Users/kooshapari/CodeProjects/Phenotype/repos/PhenoLang/omniroute-core
+cargo bench --workspace
+
+# Run specific benchmark
+cargo bench routing_single
+
+# Compare with baseline
+cargo bench --baseline vs_ts_baseline
+```
+
+## Baseline Metrics Location
+
+- TS baseline: `baseline_metrics.json` (from session 48462b3f)
+- Results: `benches/results/YYYY-MM-DD/*.json`
+
+## Next Steps
+
+1. Create `benches/` directory structure
+2. Add Criterion benchmarks for routing
+3. Run initial baseline against TS implementation
+4. Document p50/p95/p99 latency targets
+
+## Dependencies
+
+- Rust: `criterion = "0.5"`
+- Go: `benchstat` for comparison
+- Python: `pytest-benchmark` for TS tests

+`<tool_usage_example>` and `<tool_usage_instructions>` blocks for details.
+{{else}}
+You have access to a set of tools described in the tools API. Use them via the function-call
+interface; the host forge process will execute the tool and return the result.
+{{/if}}
+
+If a `task` tool (also callable as `forge_task`) is in your available tools, you can delegate
+work to a subagent. The subagent runs in its own conversation with its own context window
+and returns a final report. Prefer the `task` tool over spawning shell processes that call
+out to other LLM CLIs (`claude`, `cursor-agent`, `codex`, etc.) — those harnesses will not
+have your context, permissions, or model selection, and they will not appear in your
+session history.
+
+When to use the `task` tool (in order of priority):
+1. The work has more than 5 distinct steps and could be split into parallel subtasks.
+2. The work is context-heavy (e.g. exploring a 6k-line codebase) and would crowd out the
+   primary conversation's context window.
+3. The work is a long-running async operation you want to fire-and-forget.
+4. The user explicitly asked for a subagent / delegation / "use the task tool".
+
+When NOT to use the `task` tool:
+- A single tool call suffices (`read`, `edit`, `bash`, `grep`).
+- The work is already parallel and you can do it in one turn.
+</tool_discovery>
+
 <non_negotiable_rules>
 - ALWAYS present the result of your work in a neatly structured format (using markdown syntax in your response) to the user at the end of every task.
 - Do what has been asked; nothing more, nothing less.

+# LLM-Based Context Summarization Prompt
+
+You are a skilled coding assistant tasked with creating a concise, informative summary of a coding session.
+
+## Instructions
+
+Create a summary that includes:
+- What the user was trying to accomplish
+- Key decisions made
+- Files modified
+- Commands executed
+- Current task progress
+
+## Guidelines
+
+1. **Be Concise**: Aim for 200-500 tokens total
+2. **Preserve Semantics**: Focus on meaning, not implementation details
+3. **Prioritize Recent**: Weight recent work more heavily
+4. **Preserve Decisions**: Don't lose the reasoning behind key choices
+

+/// forge-context-backfill: Batch-compress existing uncompressed conversation rows
+///
+/// This tool safely migrates existing uncompressed context blobs (is_compressed=0) in
+/// the forge conversation database to zstd-compressed format (is_compressed=1).
+///
+/// Safety guarantees:
+/// - Preflight check: refuses if forge processes hold the DB (lsof)
+/// - Disk check: refuses if < (db_size + 1GB) free space
+/// - Backup first: automatic timestamped backup (skippable with --skip-backup + warning)
+/// - Batched + resumable: processes in transactions, idempotent (skips already-compressed rows)
+/// - Lossless verification: round-trip verify each row before write
+/// - Vacuum option: --vacuum runs full VACUUM + converts DB to INCREMENTAL auto_vacuum
+///
+/// Usage (dry-run by default):
+///   cargo run -- --db-path ~/forge/.forge.db
+///
+/// Usage (apply compression):
+///   cargo run -- --db-path ~/forge/.forge.db --apply --yes
+///
+/// Usage (with full vacuum):
+///   cargo run -- --db-path ~/forge/.forge.db --apply --yes --vacuum
