대용량 CI 로그(최대 2MB)를 스캔할 때 테스트 실패를 포함하지 않는 경우,
불필요한 정규표현식(`FAIL_SUMMARY_RE.findall`) 탐색을 방지하여 스캔 속도를 개선했습니다.
단순 문자열 존재 여부 검사(`"Error: Test failures" not in text`)를 정규표현식보다 앞서 실행하도록 순서를 변경하였습니다.

 ## 2026-06-25 - Avoid N+1 API blocking in PR checks
 **Learning:** In backend processing scripts, synchronous iterations calling an external service, such as fetching `restMergeableState` per PR, cause N+1 API bottlenecks and stall pipeline execution linearly. This matters for PR schedulers handling multiple PRs.
 **Action:** Use `concurrent.futures.ThreadPoolExecutor` for independent network calls in a loop when there are multiple items, keep empty and single-item inputs on the cheaper serial path, and bound `max_workers` to avoid API rate limits.

 ## 2024-05-19 - Pre-compile Regex Patterns in Loop-called Functions
 **Learning:** In `scripts/ci/pr_review_merge_scheduler.py`, the `scrub_sensitive_data` function was repeatedly compiling multiple regex patterns via `re.sub` for every log line or text scrubbed. This incurs measurable overhead due to cache lookups and object recreation in tightly looped string processing.
 **Action:** When using multiple regex replacements inside functions that are called frequently or process large amounts of text, define and pre-compile the regex objects at the module level (e.g., `SENSITIVE_DATA_SCRUB_PATTERNS`) and iterate over them using `pattern.sub()`.

 ## 2026-07-09 - Avoid N+1 API blocking in SBOM aggregator
 **Learning:** The `collect_inventories` function in `scripts/ci/sbom_inventory_aggregator.py` was fetching SBOMs from the GitHub dependency graph synchronously for every repository in the organization. For large organizations (up to 500 repos), this N+1 network/CLI bottleneck significantly stalled the aggregation workflow.
 **Action:** Use `concurrent.futures.ThreadPoolExecutor` to fetch SBOMs concurrently when multiple repositories are provided, bounded by a `max_workers` limit (e.g., 10) to avoid overwhelming the CLI/API, while preserving the fast serial path for single-item inputs.

+## 2024-05-24 - [대용량 로그 스캔 시 정규표현식 실행 전 O(N) 서브스트링 검증 선행]
+**Learning:** `classify_testthat_failure`에서 테스트 실패 내역이 없는 2MB 로그 파일을 대상으로 정규표현식을 실행하면 약 20ms가 소요되지만, 단순 문자열 검색은 약 1ms만 소요됩니다. 문자열 존재 여부가 정규표현식 매칭의 전제 조건일 때, 콜드 패스(Cold Path)에서 순서 최적화는 매우 큰 성능 차이를 만듭니다.

 ## [Unreleased]
-
-### Added
-
-- Added a trusted pull-request comment router for `@cwl-noema-review` and review-only `@opencode-agent` dispatches, with an organization sweep, exact-head receipts, repository allowlisting, fixed runners, immutable checkout pins, and a permanent 100% statement/branch/docstring quality gate.
-- Added exact-base `uv.lock` materialization that reconstructs standalone nested projects with a checksum-pinned official `uv` exporter, isolated frozen/offline execution, strict exact-pin and SHA-256 output validation, and complete Python 3.10/3.14 quality evidence.
-
-### Fixed
-
-- Bounded the Strix quality self-test's deterministic timeout fixtures to 3-second process and 5-second fake-sleep budgets so exact-head policy evidence completes inside the existing job limit without changing production Strix scanner timeouts, providers, credentials, or review semantics.
-- Allowed commas and ASCII parentheses in the bounded Strix changed-file path policy so legal tracked Packrat fixtures can receive exact-head security analysis, while rejecting raw `..` components before normalization and keeping controls, backslashes, whitespace ambiguity, and shell punctuation fail-closed.
-- Bound each review-agent invocation key to the wrapper's complete canonical payload, including the base branch and requesting actor; altered fields with a valid-format key now fail before durable-leader election or forwarding, and wrapper write permission is job-scoped.
-- Bound both trusted-uv quality jobs to `github.event.pull_request.head.sha` and added a permanent two-checkout regression contract so exact-head compatibility, coverage, docstring, and compilation claims cannot silently measure GitHub's generated pull-request merge revision.
-- Made Strix treat only a single LiteLLM provider-error line containing NVIDIA NIM context and model-catalog 404 evidence as cross-model fallback evidence, rejecting cross-line signal assembly and provider-like target source literals; moved the public default to Nemotron 3 Super 120B and added a second NVIDIA hosted candidate before GitHub Models without neutralizing reported vulnerabilities.
