 Status: QA PASS. Fresh controller recovery accepted for Network/Forks and ready for main merge.
 Evidence: make doctor healthy; make check passed; DB-backed package_detail_contract 4/4, projects_list_contract 1/1, and repository_network_contract 1/1 passed against localhost:55433; focused Network/Forks/API docs Vitest passed 9/9; focused system-Chrome repository-network Playwright passed setup + flow 2/2 in 21.0s.
 Fixes accepted: package settings camelCase serde IDs, project copy FOR UPDATE OF projects + workflow_key clone + org membership/base-role guard, corrected projects default-open expectation, repository_network_contract rate-limit identity isolation, and repository-network E2E now uses shared auth plus container-backed psql fallback instead of host psql.
+
+2026-05-24 - search-007 QA final lane
+- Fixed /api/repos/:owner/:repo/find to honor the PRD path-list contract: q is ignored for /find, default pageSize is 10000, and repository_ref_files is refreshed while legacy /file-finder filtering remains intact.
+- Updated the dedicated /<owner>/<repo>/find/<ref> page fetch to use the /find path-list contract for client-side fuzzy scoring.
+- Added focused DB-backed API/security coverage and focused Playwright UI/a11y/keyboard coverage; make check, focused Rust contract, and focused Playwright with /snap/bin/chromium passed.
+- QA remains blocked (qa_pass=false): full make test fails in unrelated web unit-test timeouts, and default make test-e2e cannot provision bundled Chromium on ubuntu26.04-x64 without executable override.
