🔴 (04:58) Final complete bridge matrix passed under Vitest v4.1.10: 10/10 test files and 653/653 tests in 11.56s. A warning showed delta-upgrade fallback after Patch too small: 4 bytes (need at least 32), and Vitest warned that test.poolOptions was removed in Vitest 4 and its options must now be top-level.
🔴 (04:58) Full packages/cli verification passed: generated typecheck via pnpm run generate:docs && pnpm run generate:sdk && tsc --noEmit; Biome lint checked 1,030 files in 53s with no fixes; check:deps found no runtime dependencies in package.json; check:errors found no error-class anti-patterns; check:patches confirmed patched dependency versions match installed versions; and check:stale-refs found no stale package-manager references across 27 files with current package manager pnpm.
🔴 (04:58) Generation outputs included src/generated/banner-sixel.ts at 640×155 and 4,216 sixel bytes; src/generated/search-parser.js at 31.1 KB plus src/generated/search-parser.d.ts; 36 command documentation pages plus command index/configuration pages; plugins/sentry-cli/skills/sentry-cli/SKILL.md, 36 reference files, skills index JSON, and src/generated/skill-content.ts; and SDK artifacts src/sdk.generated.ts and src/sdk.generated.d.cts from 112 discovered commands.
🔴 (04:58) Pre-review working-tree diff comprised 6 files with 220 insertions and 24 deletions: packages/cli/src/lib/binary.ts, packages/cli/src/lib/ghcr.ts, packages/cli/src/lib/upgrade.ts, packages/cli/test/commands/cli/upgrade.test.ts, packages/cli/test/lib/ghcr.test.ts, and packages/cli/test/lib/upgrade.test.ts.
🟡 (04:58) Assistant reported the body-validation patch passed 653/653 bridge tests, generated typecheck, lint, and policy checks, then began a six-file diff review focused on validator strictness and unintended fixture changes before commit/push.
🟡 (04:59) Final diff review found a classification bug: validatePinnedGitHubRelease() broadly caught and rewrapped UpgradeTransportError, which would prevent automatic cache fallback when a pinned-response body truly terminates. Fix: remove that broad catch so transport typing propagates; also validate the actual runtime shape of GHCR tag-list responses.
🟡 (04:59) parseUpgradeJson(response, signal, invalidMessage) in packages/cli/src/lib/binary.ts was reviewed as preserving exact signal.reason when aborted, mapping SyntaxError to terminal UpgradeError("network_error", invalidMessage), and mapping other body-read failures to UpgradeTransportError with stringifyUnknown(error).
🟡 (05:00) Assistant added a direct parseUpgradeJson() regression triplet in packages/cli/test/lib/binary.test.ts to lock three distinctions: cancellation preserves reason identity, body termination remains a transport error, and malformed JSON is a terminal metadata error.
🟡 (05:00) First focused formatting/lint attempt failed with 8 errors because automated import insertion placed the literal parseUpgradeJson, at EOF line 974 rather than in the existing import from ../../src/lib/binary.js; resulting errors included unexpected EOF, unused expression/comma-operator diagnostics, and undeclared parseUpgradeJson usages at lines 514, 525, and 536. Assistant diagnosed this as a test-only import-edit error; production code was unaffected.
🟡 (05:01) Assistant repaired packages/cli/test/lib/binary.test.ts by moving parseUpgradeJson into the existing binary import list and deleting the stray EOF line, then committed to rerunning focused and full verification before any commit.
🔴 (05:02) Focused tests across test/lib/binary.test.ts, test/lib/ghcr.test.ts, and the associated upgrade suite ran 297 tests: 296 passed and 1 failed. The sole failure was test/lib/ghcr.test.ts > listTags > returns empty array when response has no tags field, which received UpgradeError: GHCR tag list returned invalid metadata from fetchTagPage() at src/lib/ghcr.ts:570.
🟡 (05:02) Assistant determined the failing GHCR test represented an established API contract: an object with no tags field is an empty page, whereas non-object payloads, present non-array tags, and non-string tag entries must still fail closed. packages/cli/src/lib/ghcr.ts was changed to restore missing-tags → [] while retaining strict validation for malformed present values.
🔴 (05:03) After the missing-tags behavior fix, TypeScript reported src/lib/ghcr.ts(577,27): error TS2322: Type 'unknown' is not assignable to type 'string[]'; the nested "tags" in data validation did not preserve narrowing through return "tags" in data ? data.tags : [].
🟡 (05:03) An initial patch for the TypeScript narrowing issue failed because Biome had reformatted the condition, so the expected patch context no longer matched lines 563-577. Assistant inspected the exact current source and then successfully split object validation from field validation, producing a concretely narrowed string[] return.
🟡 (05:03) Assistant started another focused and full verification cycle after the GHCR tag-list narrowing fix; no resulting test, typecheck, commit, or push outcome was available in this segment.
