• 🟡 (03:56) Assistant defined the prefetched-release test strategy: raw prefetched arrays deliberately bypass the compile-time branded type solely to verify runtime rejection; same-source success uses fetchRecentReleases(); source-mismatch tests use branded data normalized for the opposite source.
• 🟡 (03:56) Test changes were applied to four files: packages/cli/test/lib/binary.test.ts, packages/cli/test/lib/ghcr.test.ts, packages/cli/test/lib/upgrade.test.ts, and packages/cli/test/lib/release-notes.test.ts.
• 🟡 (03:56) Assistant clarified the pinned-stable npm regression contract: when tracking nightly, a stable npm pin validates its version through npm, then fetches stable release notes from GitHub; the test must reject exact-tag/latest GitHub validation probes while requiring the stable GitHub changelog endpoint.
• 🟡 (03:56) Assistant added opposite-source branded-prefetch rejection coverage.
• 🟡 (03:57) Further test updates were applied to packages/cli/test/commands/cli/upgrade.test.ts and packages/cli/test/lib/release-notes.test.ts.
• 🟡 (03:57) Assistant reported cancellation and provenance regressions were implemented, including the split whereby stable npm pin validation uses npm while stable changelog provenance uses GitHub.
• 🟡 (03:57) Validation tooling checked 10 files in 5s and automatically fixed 5 files.
• 🟡 (03:57) Bridge test matrix passed completely: 9 test files passed and 505/505 tests passed under Vitest v4.1.10; duration was 11.81s with transform 9.17s, setup 319ms, import 16.59s, tests 10.00s, and environment 1ms.
• 🟡 (03:57) Test output included a Vitest 4 deprecation warning: test.poolOptions was removed and its prior options are now top-level configuration.
• 🟡 (03:57) Test output included the expected delta-upgrade fallback warning: Delta upgrade failed (Patch too small: 4 bytes (need at least 32)), falling back to full download.
• 🟡 (03:57) Assistant concluded all 505/505 bridge tests pass with arbitrary abort-reason propagation and strict branded release provenance, then proceeded toward generated typecheck, lint, policy checks, final diff review, and committing the final blocker fixes.
