If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Summary by CodeRabbit
WalkthroughChangesModule B contract documentation
Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🟡 Moderate · up to The docs define Module B’s integration contracts and runbook, but the current text leaves unresolved handling for duplicate content, source validation, SQLite claim behavior, and retry idempotency, while the UNCERTAIN path remains inconsistent with the stated consumer filter. These gaps could cause failed local or CI execution, lost or duplicated data, or stranded queue rows, so merge should wait for clarification or explicit owner acceptance. Possibly related PRs

In `@docs/gsoc_2026_module_b/module_a_contract.md`:
- Around line 186-188: Update the fenced code blocks in module_a_contract.md
around the referenced sections to specify the text language identifier on both
opening fences, resolving the MD040 markdownlint violations without changing
their contents.
- Around line 38-39: Align the run-scoping contract across Module A and Module
B: require the top-level harvest_input.pipeline_run_id and the payload
record.pipeline_run_id to contain identical values, or make Module B reject rows
when they differ. Update the relevant delivery documentation and validation flow
referenced by the module_b_runbook and queue_writer behavior, preserving
processing only for matching run identifiers.
- Around line 90-96: Update the Required locator payload contract to document
the URL field required for the reserved feed_item kind, including its mapping to
the RSS source’s feed_url value. Ensure the documented feed_item shape matches
the schema validation, or explicitly mark the RSS locator shape incomplete until
the model and contract are aligned.
In `@docs/gsoc_2026_module_b/module_b_runbook.md`:
- Line 55: Update docs/gsoc_2026_module_b/module_b_runbook.md:55 to reference
ChangeRecord v0.4 and link the current Module A input contract. Update
docs/gsoc_2026_module_b/module_c_contract.md:18 to reference Module A contract
v0.4 and document the database hand-off and feed_item changes.
- Around line 114-116: Update the “Recall-first” guarantee in the runbook to
apply only to valid, successfully parsed records, explicitly excluding rows
marked error from the claim. Document how error rows are retried or reconciled
so they can eventually be reprocessed.
- Around line 34-35: Add blank lines before and after each Markdown table near
the “Environment variables” sections and the other referenced table blocks, and
annotate the code fence near the runbook’s final section with an appropriate
language such as text. Keep the table and fenced content unchanged aside from
these lint fixes.
In `@docs/gsoc_2026_module_b/module_c_contract.md`:
- Around line 11-12: Update Module C’s shipped C0 consumer filter to select both
KNOWLEDGE and UNCERTAIN labels, matching the contract’s canonical read query and
the retention behavior in B. Ensure the documentation does not claim the modules
are synchronized until this consumer change is applied; otherwise mark it
explicitly as a required follow-up.
- Line 12: The “column-for-column” parity claim for KnowledgeQueueItem is
unsupported by the current read-side projection. Update the documentation to
describe the actual schema/query fields, including source_path and the canonical
{source, text, confidence} projection, or first align the consumer and tests
before retaining the parity claim.
- Around line 110-118: Update the Module C contract to define a single
schema-supported atomic claim protocol: either require one transaction to hold
SELECT ... FOR UPDATE SKIP LOCKED through mapping and the consumed_at update, or
explicitly add claim fields with claim, completion, and timeout-reset SQL.
Remove the alternative claim-token wording unless its fields and recovery
queries are fully specified, ensuring concurrent consumers cannot duplicate work
or leave rows permanently in progress.

| - **Module C consumes both `KNOWLEDGE` and `UNCERTAIN`.** The canonical read query now selects `llm_label IN ('KNOWLEDGE', 'UNCERTAIN')` (was `= 'KNOWLEDGE'`). B's `llm_label` is a confidence signal, not a routing directive: C consumes every non-NOISE row and decides internally which chunks need Module D's HITL review. This keeps recall-first intact end to end — no security chunk is stranded in the queue for a label that has no downstream consumer. | ||
| - **Verified against Module C's shipped consumer (PR #1011).** C's `KnowledgeQueueItem` now mirrors this table column-for-column (all 23 columns, both `github` and `rss` provenance branches), and stamps `consumed_at` as its only write. (#1011 as shipped filters `llm_label = 'KNOWLEDGE'`; per the bullet above, its C0 read filter should be updated to `IN ('KNOWLEDGE', 'UNCERTAIN')`.) |

Do not publish the UNCERTAIN guarantee before C consumes it.
The contract requires C to select KNOWLEDGE and UNCERTAIN, but Line 12 states that the shipped C0 filter still uses llm_label = 'KNOWLEDGE'. B retains UNCERTAIN rows, as shown by application/tests/noise_filter/queue_writer_test.py Lines 56-69. Update C0 in the same change, or mark this as a required follow-up and do not describe v0.3 as synchronized.

- Line 40: Update the Module C contract’s duplicate-handling and provenance
sections to define behavior for UNIQUE(content_hash) conflicts, including how
Module B handles repeated inserts without aborting or silently dropping records.
Specify and preserve a many-to-one provenance representation so every Module A
origin remains traceable, including the related fields around the
provenance/traceability definition.
- Line 118: Align the documented claim protocol with the supported database
backends: in the contract’s concurrent-consumer guidance, define a
SQLite-compatible claim and timestamp flow without FOR UPDATE SKIP LOCKED or
NOW(), and add coverage for it, or explicitly require PostgreSQL for every
claim-protocol test. Keep the existing PostgreSQL transaction semantics
documented unchanged.

Clean re-raise of the Module B integration docs (supersedes #1018, which carried a noisy merge commit from a mid-review branch update). Same docs-only change, branched off latest
main, with CodeRabbit's #1018 review folded in.These three integration docs for Module B (Noise/Relevance Filter) were kept local / Slack-shared during Weeks 1–5. Committing them so the contract surface lives in-repo alongside the code, reviewable by the maintainer and sister-module contributors. Reconciled against the current merged code and Module C's consumer (#1011):
module_a_contract.md, v0.4): delivery is the orchestrated hand-off — A writes toharvest_input(JSONB payload +pipeline_run_id+status); B reads viacre.py --run_noise_filter --run_id. rsslocator.kindreserved value aligned tofeed_item(matches C's consumer in week_8: Module C (The Librarian) — live B→C integration, docs, and the regression gate #1011).module_c_contract.md, v0.3): mirrors B's shippedknowledge_queuetable column-for-column (verified against week_8: Module C (The Librarian) — live B→C integration, docs, and the regression gate #1011). Module C consumes bothKNOWLEDGEandUNCERTAIN—llm_labelis a confidence signal, not a routing directive; C decides Module D escalation itself. Concurrent consumers claim rows viaFOR UPDATE SKIP LOCKED; canonical read orders bycreated_at, id.module_b_runbook.md, v0.2): setup (withmake alembic-guardrailbeforeflask db upgrade), invocation, completion signal, guarantees..gitignoregets three!negations (the repo blanket-ignores*.md) — same pattern already used formodule_B_mideval_blog.md. Docs-only; no code or schema changes.CodeRabbit (#1018) addressed: version metadata synced across headers/footers/cross-refs; Alembic guardrail added before the documented upgrade;
ORDER BY created_at, idtiebreaker; concurrent-consumer claiming hardened (FOR UPDATE SKIP LOCKED+ abandoned-claim recovery). One item intentionally held: Module C consumingUNCERTAINis a deliberate, coordinated contract change (recall-first — without it, UNCERTAIN rows strand in the queue since Module D doesn't exist yet; C's C0 filter is to be updated in #1011), not a revert toKNOWLEDGE-only.
