Subject: [PATCH 01/11] Prioritize relevant crawl URLs without changing default
 BFS

Adds an opt-in best_first crawl strategy with deterministic URL scoring so targeted crawls spend page budget on more relevant URLs first while preserving legacy BFS behavior by default.\n\nConstraint: Must not duplicate open crawl-job/static-fetch PRs or change default crawl output.\nRejected: Content/LLM ranking | would expand scope and conflict with OpenChrome core boundaries.\nConfidence: high\nScope-risk: narrow\nDirective: Keep future scorer changes deterministic and fixture-gated; do not make public live-site ordering a CI gate.\nTested: npm run build -- --pretty false; npm test -- --runInBand tests/core/crawl/url-scorer.test.ts tests/core/tools/crawl.engine.test.ts; npm run lint:changed\nNot-tested: Full npm test suite; live OpenChrome crawl smoke.

Subject: [PATCH 03/11] Keep Cursor verification tolerant of Tier 1 growth

The Cursor smoke test should prove core tool visibility without failing every develop-based PR when additional Tier 1 tools graduate.

Constraint: Hosted CI currently reports 45 Tier 1 tools while the test hard-coded 39.

Rejected: Raising the exact expected count to 45 | that would recreate the same brittle failure on the next Tier 1 graduation.

Confidence: high

Scope-risk: narrow

Directive: Assert required core tools explicitly and avoid exact catalog-size checks in cross-client smoke tests.

Tested: npx jest --runInBand tests/cross-env/cursor-verification.test.ts

Not-tested: Linux Node 20/22 local execution; hosted CI pending after push.

Subject: [PATCH 04/11] Make console baseline portable across line endings

The console_capture regression should compare response shape, not fail Windows CI because checked-out JSON fixtures use CRLF line endings.

Constraint: Windows CI reads the baseline fixture with CRLF while JSON.stringify emits LF.

Rejected: Updating the fixture to Windows line endings | that would break Unix runners and still encode platform formatting into the assertion.

Confidence: high

Scope-risk: narrow

Directive: Normalize platform line endings before snapshot-style string comparisons.

Subject: [PATCH 05/11] Accept clean SIGTERM reports in health gating tests

The health endpoint integration test should treat both code=0 and signal=SIGTERM as clean shutdown outcomes after sending SIGTERM.

Constraint: CI can report SIGTERM exits as code=null even when teardown is graceful.

Rejected: Extending timeouts | the failure is the accepted exit shape, not startup or shutdown latency.

Confidence: high

Scope-risk: narrow

Directive: Avoid platform-specific assumptions for Node ChildProcess signal exit reporting.

The storage-size E2E should measure complete persisted JSON states rather than a zero-byte file observed while the async writer is truncating and rewriting.

Subject: [PATCH 09/11] Isolate HTTP auth ports across test workers

Make the HTTP bearer auth regression allocate its port range from the Jest process id before using per-case ports, avoiding collisions across parallel worktrees and CI shards.

Constraint: the best-first PR now includes the shared transport suite after develop merges and should not inherit fixed-port flakes.
Rejected: Relying on sequential suite order | the test must remain robust under parallel verification.
Confidence: high
Scope-risk: narrow
Directive: Keep transport tests independent of globally fixed loopback ports.
Tested: npx jest tests/transports/http-bearer-auth.test.ts --runInBand --forceExit

Subject: [PATCH 10/11] Parse admin key JSON through worker noise

Make the admin-keys JSON helper scan for a parseable JSON array instead of slicing from the first bracket, so Jest worker log prefixes cannot corrupt list --json assertions.

Constraint: Ubuntu 18 full-suite CI captured bracketed worker noise before the CLI JSON payload.
Rejected: Assuming stdout starts with JSON | the in-process harness intentionally shares stdout with Jest capture hooks.
Confidence: high
Scope-risk: narrow
Directive: CLI tests that tolerate worker noise should locate the actual machine-readable payload, not rely on stream position.
Tested: npx jest tests/cli/admin-keys.test.ts --runInBand --forceExit; git diff --check
Not-tested: Full multi-OS GitHub Actions matrix after this commit.

Subject: [PATCH 11/11] Preserve shallow best-first crawl candidates

Keep the shallower queued entry when best-first discovers the same URL at multiple depths, so an early deep discovery cannot cause a later in-scope discovery to be skipped by max_depth filtering. A depth tie-breaker also preserves shallow preference when scores match.\n\nConstraint: best_first sorting is score-based, so queue de-duplication must not discard a shallower path before max_depth checks run.\nRejected: Pure URL set de-duplication | can leave only an over-depth candidate for an otherwise crawlable URL.\nConfidence: high\nScope-risk: narrow\nDirective: Best-first queue bookkeeping should retain the minimum discovered depth for each queued URL.\nTested: npm run build; npx jest tests/core/tools/crawl.engine.test.ts tests/core/tools/crawl.legacy-snapshot.test.ts tests/core/crawl/url-scorer.test.ts --runInBand --forceExit; npm run lint:tool-schemas; git diff --check\nNot-tested: Full CI matrix locally.\n\nCo-authored-by: OmX <omx@oh-my-codex.dev>
