• 🟡 (03:51) Immutable correctness review task ses_f76943a43ffeN6sOGKQvjeI3sQ initially completed with an empty report; assistant deemed the report invalid and resumed the same reviewer once with an explicit evidence-or-blocker requirement while leaving security review ses_f7693f650ffeOc12prCbNEwO6Z active and unduplicated.
• 🔴 [enforced-workflow] (03:51) User reiterated that PR #1569 review tasks must be awaited through notifications only: never poll or duplicate their work.
• 🔴 [enforced-workflow] (03:51) User required checking CI, Warden, and review threads for exact head f1c10a6cb1a753b8c4b8c613cd78735c3f12cba6; merging only after substantive MERGE reports and all gates; and then verifying the immutable commit’s parents and tree.
• 🟡 (03:51) PR #1569 remained OPEN, MERGEABLE, but merge state BLOCKED, with base ec83887a16f780f32fba4b7d710bad262dba3a22 and head f1c10a6cb1a753b8c4b8c613cd78735c3f12cba6.
• 🟡 (03:51) Exact-head checks succeeded for Detect Changes, CodeQL Analyze (actions), CodeQL Analyze (javascript-typescript), CodeQL Analyze (python), dependency-review, Secret Scan, Validate generated files, Lint & Typecheck, Unit Tests, Eval SKILL.md, Build Binary (linux-x64), Build Binary (darwin-arm64), Build npm Package (smoke Node 20), Build npm Package (smoke Node 22), Build npm Package (smoke Node 24), Build Docs, Cursor Bugbot, Seer Code Review, both Socket Security checks, Vercel – cli, Vercel – sentry-local, and semgrep-cloud-platform/scan.
• 🟡 (03:51) Exact-head checks still in progress were warden and E2E Tests; Codemod tests, Run skill eval, Generate Delta Patches, and Publish Nightly to GHCR were skipped.
• 🟡 (03:51) A standalone CodeQL summary check failed with 1 new high-severity security alert even though all three language-specific CodeQL jobs passed.
• 🟡 (03:51) Review-thread inspection found six resolved threads and one unresolved, non-outdated thread PRRT_kwDOQm6jAs6g66tk at packages/cli/test/commands/cli/upgrade.test.ts:1293.
• 🔴 (03:51) User-provided review evidence stated the shell installer’s Toolkit latest-release parser accepts the first matching cli@X.Y.Z tag_name and never inspects GitHub prerelease or draft flags, unlike the TypeScript resolver; therefore a prerelease with a stable-looking cli@ tag can be installed as the latest stable CLI.
• 🔴 (03:51) User-provided regression contract stated an MCP-only HTTP 200 must make exactly one Toolkit request and never contact getsentry/cli.
• 🔴 (03:51) User-provided regression contract stated terminal HTTP 403 handling must never contact the legacy repository; only a genuine HTTP 404 permits compatibility fallback/not-found classification.
• 🟡 (03:51) Assistant determined the CodeQL high alert at packages/cli/test/commands/cli/upgrade.test.ts:1293 was valid because request.includes("api.github.com") did not prove that no GitHub API request occurred; chosen fix was parsed URL-origin comparison rather than substring matching.
• 🟡 (03:52) Updated packages/cli/test/commands/cli/upgrade.test.ts for exact parsed-origin checking. Biome checked the file in 1419ms with no fixes; focused Vitest v4.1.10 passed 1 test with 41 skipped out of 42 in 7.52s (5.39s transform, 70ms setup, 7.19s import, 54ms tests), while repeating the test.poolOptions removal deprecation.
• 🟡 (03:52) After the CodeQL-test correction, the worktree differed from origin/feat/toolkit-bridge-upgrade only in packages/cli/test/commands/cli/upgrade.test.ts, with 5 insertions and 3 deletions; the correction had not yet been committed or pushed.
• 🟡 (03:53) Resumed immutable correctness review ses_f76943a43ffeN6sOGKQvjeI3sQ returned DO-NOT-MERGE with one MUST-FIX: arbitrary caller abort reasons were preserved for direct/redirected blobs but not across GitHub source probes or GHCR token, manifest, and tag requests.
• 🔴 (03:53) User-provided correctness requirement stated caller cancellation reasons must always propagate unchanged; otherwise they can be misclassified as network failures or retried, delaying shutdown.
• 🟡 (03:53) Correctness root cause in packages/cli/src/lib/ghcr.ts:135-140: fetchWithRetry() converts every non-Error rejection into new Error(String(error)) before comparing it with externalSignal.reason, so primitive/object abort-reason identity cannot match and cancellation may be retried or ultimately wrapped as UpgradeError.
• 🟡 (03:53) Correctness root cause in packages/cli/src/lib/binary.ts:317-327: fetchUpgradeProbe() preserves only caught Error objects named AbortError; an external abort carrying Error("cancelled"), a string, or an object is wrapped as an UpgradeError("network_error", ...).
• 🟡 (03:53) Correctness root cause in packages/cli/src/lib/upgrade.ts:594-596: fetchLatestNightlyVersionWithSource() replaces an already-aborted signal’s original reason with new AbortError().
• 🟡 (03:53) Correctness reviewer confirmed direct and redirected blob paths already handle the invariant correctly by calling rethrowExternalAbort() before error conversion at packages/cli/src/lib/ghcr.ts:400-405 and packages/cli/src/lib/ghcr.ts:442-448.
• 🟡 (03:53) Required abort fix: before normalizing any caught value, check externalSignal?.aborted and throw externalSignal.reason unchanged; apply the same rule in fetchUpgradeProbe(); and for an already-aborted signal throw signal.reason instead of constructing AbortError.
• 🟡 (03:53) Correctness reviewer prescribed four deterministic regressions in order: 1. abort getAnonymousToken() with a primitive reason, make mocked fetch reject that exact reason, assert identity and exactly one request; 2. repeat for resolveUpgradeSource(); 3. call fetchLatestNightlyVersion() with an already-aborted signal carrying a non-Error object and assert rejection with that exact object; 4. repeat through fetchManifest() or listTags() to cover fetchWithRetry().
• 🟡 (03:53) Correctness reviewer verified exact pins bypass latest discovery: pinned resolution occurs first and the nullish expression does not invoke latest discovery when pinnedTarget exists at packages/cli/src/commands/cli/upgrade.ts:334-352; command coverage asserts no per_page=100 request at packages/cli/test/commands/cli/upgrade.test.ts:358-403.
• 🟡 (03:53) Correctness reviewer verified target-driven routing: nightly targets migrate every non-curl installation based on isNightlyVersion(target) at packages/cli/src/commands/cli/upgrade.ts:1076-1080, while stable targets retain npm/Homebrew behavior and stable Homebrew pins are rejected at :257-264.
• 🟡 (03:53) Correctness reviewer verified one-off pinned-nightly tracking: artifact channel derives from the target at packages/cli/src/commands/cli/upgrade.ts:276-281 and :1023-1043, while setup receives the existing tracking channel; the npm migration regression verifies --channel stable and unchanged persisted tracking at packages/cli/test/commands/cli/upgrade.test.ts:1128-1206.
• 🟡 (03:53) Correctness reviewer verified stable semantic-prerelease filtering: latest discovery excludes GitHub prerelease flags and semantic prerelease versions before semantic sorting at packages/cli/src/lib/upgrade.ts:488-514; delta/recent normalization uses the same filters at packages/cli/src/lib/delta-upgrade.ts:100-120; stable changelog input passes through that normalization at packages/cli/src/lib/release-notes.ts:594-646.
• 🟡 (03:53) Correctness reviewer verified branded normalized provenance: normalized release arrays carry a non-enumerable symbol whose structural source key includes GitHub repo, GHCR repo, and tag prefix at packages/cli/src/lib/delta-upgrade.ts:75-120.
• 🟡 (03:53) Correctness reviewer verified raw cross-source data handling: prefetched releases bypass normalization only when structural provenance matches; all other arrays are normalized against the requested source at packages/cli/src/lib/release-notes.ts:640-642; tests cover copied source objects, raw Toolkit data, and unprefixed cross-source rejection at packages/cli/test/lib/release-notes.test.ts:361-434.
• 🟡 (03:53) Correctness reviewer verified exact metadata: stable pins require the exact source-prefixed tag_name and reject malformed successful responses without fallback at packages/cli/src/lib/upgrade.ts:697-739; nightly annotations require exact numeric X.Y.Z-dev.TIMESTAMP SemVer at packages/cli/src/lib/ghcr.ts:322-336; pinned manifests must equal the requested version at packages/cli/src/lib/upgrade.ts:683-708.
• 🟡 (03:53) Correctness reviewer verified 404-only fallback: source probing advances only on HTTP 404 at packages/cli/src/lib/binary.ts:338-354; nightly GHCR fallback checks GhcrManifestHttpError.status === 404 at packages/cli/src/lib/upgrade.ts:604-633; transport errors, HTTP 403, malformed HTTP 200 responses, and matching message text do not trigger fallback.
• 🟡 (03:53) Correctness reviewer verified source affinity through changelog, delta, prefetch, token, manifest, blob, and full-download calls, including packages/cli/src/commands/cli/upgrade.ts:898-903, :1023-1043; packages/cli/src/lib/delta-upgrade.ts:176-224, :618+; and packages/cli/src/lib/upgrade.ts:623-624, :991-1005.
• 🟡 (03:53) Correctness reviewer verified pagination: next links must use HTTPS, host api.github.com, a release-list path, and a canonical positive page number; implementation discards supplied host/path/query, rebuilds the request from the selected source, and rejects cycles at packages/cli/src/lib/upgrade.ts:488-533.
• 🟡 (03:53) Correctness reviewer verified redirect authorization: GHCR receives the bearer token with manual redirects, while redirected storage receives only User-Agent, at packages/cli/src/lib/ghcr.ts:388-440.
• 🟡 (03:53) Correctness reviewer verified SHA/delta/cache/offline behavior: source forwarding leaves binpatch inline SHA verification, cache, and offline contracts unchanged; delta failures still return null for full-download fallback, while explicit offline misses fail without network access.
• 🟡 (03:53) Correctness reviewer verified API compatibility: existing argument order and public exports remain intact; source parameters were appended or implemented through a backward-compatible UpgradeSource | AbortSignal discriminator.
• 🟡 (03:53) Correctness review inspected all 16 changed source/test files exclusively through immutable Git objects and reported immutable diff SHA-256 f04818a2473a139b9ba1a0a0c94bb9fb80e9cc23788d06cf666c1deabd365f6e; it executed no tests because review scope was limited to immutable Git objects.
• 🟡 (03:53) Assistant chose one cancellation invariant across all affected paths: whenever the caller signal is aborted, catches must rethrow signal.reason unchanged before normalization or retry; planned deterministic primitive/object abort tests at the GHCR token, source-probe, and already-aborted nightly boundaries.
• 🟡 (03:54) Test discovery found resolveUpgradeSource coverage in packages/cli/test/lib/binary.test.ts and getAnonymousToken coverage in packages/cli/test/lib/ghcr.test.ts; the first attempted apply_patch to packages/cli/test/lib/ghcr.test.ts failed verification because the expected test text test("propagates caller cancellation without retry", async () => { was not present, so no abort fix from that patch was applied.
