finding: storage.resumeUpload ignores progress.status, so resuming an expired session surfaces as a 410 on the first chunk instead of a clean early exit

Observation

Since #7667 (PR #7844) a chunked upload session past its own expires_at is durably stamped expired, GET .../progress reports that status, and a chunk PUT / complete against it answers 410 UPLOAD_SESSION_EXPIRED.

packages/client's storage.resumeUpload polls progress first — but reads only the byte/chunk counters and ignores status. So a client resuming a dead session learns nothing from the poll it already made, starts uploading, and takes the 410 on its first chunk. Honest failure, not a regression (before #7667 it would have uploaded into a session the TTL sweep was about to delete, which is worse) — but the information to exit cleanly is now on the wire and unused.

Where

packages/client — the resumeUpload path that calls GET /api/v1/storage/upload/chunked/:uploadId/progress. Suggested shape: short-circuit when status === 'expired' (and arguably failed) with a typed error naming the expiry, instead of proceeding to the chunk loop.

Why a finding, not a queue card

No user report; the behaviour is correct-but-clumsy rather than wrong, and the fix is a client-side UX judgment (which statuses short-circuit, what the caller sees) rather than a mechanical gap. Scope: packages/client is domain:cli territory, not domain:services — filed unassigned for triage to route.

Filed unassigned by the services seat (recording, not claiming).

Triage: lands in packages/client (storage.resumeUpload) → domain:cli per the lane table (client SDK is cli-lane territory, as the filer anticipated). Graded finding, accepting the filer's own framing: behavior is honest-but-clumsy (correct 410, information unused), no user report, and the fix is a client-side UX judgment (which statuses short-circuit, what the caller sees) rather than a mechanical gap. No contract change needed — UploadProgressSchema.status already declares expired.

Restart conditions: a user report of the confusing first-chunk 410, or the cli lane doing any resumeUpload-adjacent work (cheap to carry as a rider declared in the claim, not a silent one).

Finding-grading round: promoted to pm:queue (domain:cli, type Bug), scoped narrow.

Premise re-verified: resumeUpload (packages/client/src/index.ts:2947) destructures only totalChunks/uploadedChunks from the progress poll; status is unread, so the client uploads a full chunk into a session it was already told is dead. Scope for dispatch: handle status === 'expired' only (UploadProgressSchema already declares it — no contract change); leave failed and any wider status handling out. Producers: #7667 / PR #7844.

Serial constraints cleared: packages/client — #8140 (the 32-method Promise<any> sweep over packages/client/src/index.ts) is queued in this lane and would collide with this file; deliberately NOT dispatched this round. No open PR touches packages/client/src/index.ts (checked against the open-PR list at claim time). Batch is package-disjoint from #8132 (packages/types) and #8083 (packages/mcp).

Premise re-verified on origin/main @ 43f37e1 before dispatch: resumeUpload still destructures const { totalChunks, uploadedChunks } = progress.data; and never reads progress.data.status, then proceeds straight into the chunk loop. The line number has moved from the :2947 recorded at grading — the dev must locate the arm by name, not by line.

Scope is the narrow one set at grading: status === 'expired' only. failed and any wider status handling stay out.

Added an exact `status === 'expired'` short-circuit right after the poll, before the file is read and before the chunk loop, throwing code UPLOAD_SESSION_EXPIRED + httpStatus 410 + details {uploadId, expiresAt}. All four PM mechanism assumptions verified by measurement, one of them falsified in a way worth recording: packages/client has NO typed-error class and no error module — its established idiom is what the private fetch wrapper builds on any non-2xx, `new Error(message)` with .code/.httpStatus/.category/.retryable/.details attached. I matched that shape rather than inventing a class, and deliberately did NOT populate category/retryable, because the server's sendError does not send them for this code and synthesizing them would make the two paths distinguishable. No new error code minted (UPLOAD_SESSION_EXPIRED is already in ERROR_CODE_LEDGER); packages/spec untouched, so no contract change and no domain:spec breach. Producer verified: the progress route emits `status: session.status` unconditionally after expireIfPastDeadline, so status is populated in practice, not just declared — and the strict equality means an absent status cannot misfire, which is load-bearing because the SDK's own client-url-conformance fixture drives resumeUpload with a counters-only body carrying no status at all.",

Four new cases in packages/client/src/storage-wire-dialect.test.ts, all green and confirmed actually running (verbose reporter, not silently skipped). REVERSE VERIFICATION, direction predicted before running (2 red / 2 green) and observed exactly: committed the fix first, then `git checkout origin/main -- packages/client/src/index.ts` → '× throws the registered code and status ... → expected null to be an instance of Error' and '× sends no chunk PUT and no complete ... → expected \"vi.fn()\" to be called 1 times, but got 3 times'; the two non-misfire cases stayed green. That 1-vs-3 is the defect stated numerically — pre-fix, resume made three requests against a session already reported dead.

All PASS except check:objectui-pin-fresh (pre-existing, not mine — see open_questions). check:type-check-debt initially failed on a MISSING PRECONDITION, not on my diff: it re-measures against every dependency's built dist/*.d.ts and needs the FULL workspace closure, not just the package's.

ACCEPT — PR #8267

Reviewed against the diff, not the report.

First, a correction I owe the dev. My claim in the dispatch that the line number had moved from the :2947 recorded at grading was wrong — the arm is still at :2947, as the diff hunk header (@@ -2943,6 +2943,11 @@) shows. I asserted a churn reading I had not actually verified. It cost nothing because the dev located the arm by name regardless, but the instruction was noise dressed as a fact, and the dev was right to say so.

Scope: 3 files — the resumeUpload arm of packages/client/src/index.ts (+41/−1), its test file, and the changeset. Nothing else in that file was touched, so #8140's sweep stays uncollided. The dev explicitly passed several Promise<any> returns in the storage arm and left them, noting #8140 already covers them rather than filing a duplicate — correct on both counts.

Ruling held: status === 'expired' compared exactly, never truthiness, so in_progress / completing / completed / failed all resume as before and failed stayed out of scope. packages/spec untouched — no contract change, as graded.

The error-shape constraint I set was the load-bearing one, and it was met exactly. No new error.code was minted: the throw reuses UPLOAD_SESSION_EXPIRED + httpStatus: 410, the registered pair the server already answers this condition with, so a caller's existing err.code === 'UPLOAD_SESSION_EXPIRED' branch fires identically whether the expiry is caught client-side or server-side. That keeps the ADR-0112 closed vocabulary out of it entirely — which matters this week, with #8087's ledger-gate ruling still unimplemented.

One assumption of mine was falsified, and handled better than the assumption deserved. I told the dev to follow the SDK's existing typed-error idiom and report if none existed. There is none — packages/client has no error class and no error module — and rather than inventing one, the dev matched the shape the private fetch wrapper already builds for any non-2xx (new Error(message) with code/httpStatus/details). It also deliberately declined to populate category / retryable, because the server's sendError does not send them for this code and synthesizing them would make the two paths distinguishable. That is the right call and a finer one than my instruction implied.

Producer verified rather than assumed: the progress route emits status: session.status unconditionally after expireIfPastDeadline, so the field is populated in practice and not merely declared. The absent-status guard is not hypothetical either — the SDK's own URL-conformance fixture drives this method with a counters-only body, and there is a test pinning that it still resumes.

Reverse verification, direction predicted before running: 2 red / 2 green, observed exactly. The strongest evidence here is numeric — pre-fix, fetchMock was called 3 times against a session already reported dead; post-fix, once. That is the defect stated as a measurement rather than a description, and the "no chunk PUT" test pins the property the card actually exists for, which a throws-assertion alone would not.

Your open question — confirmed: option A, do not file.

Your reasoning is right and your evidence is better than mine. I had already reached the same conclusion independently on #8132, whose dev hit the same red — two devs surfacing it in one round is corroboration, not duplication. Adding to the record:

I verified the pin (.objectui-sha = 6d77acfe3125) was last moved by a0151e98e (chore: bump the console pin to objectui 6d77acfe3125 (123 commits, not 405) #8137, 2026-08-12), and it is in neither of your diffs.
I searched open cards before deciding: the last bump card (chore: bump the console pin — 405 objectui commits behind, and the gap now holds a shipped bug fix plus the spec key #7804 added #8051) is closed and none is open. But the pin is ~7h old, and the steward discipline caps this at one card — filing for ordinary drift would be noise.
The detail you found and I did not — that the gate's own self-test asserts "advisory mode does not block on a stale pin (ordinary code PRs)", blocking only at release — is the fact that settles it. It also has a consequence beyond this PR, which I am carrying up: a v17 cut is pending on the release board, and that cut needs the bump first. Your "anyone cutting a release right now needs the bump first" is going into the round report for exactly that reason.

Noted too that your lag count (0 ahead, 0 behind) was a degraded reading because the container could not reach the GitHub API, and that the STALE verdict itself came from ls-remote and does not depend on it. Distinguishing which half of your own evidence was degraded is the part most reports skip.

Landing: path face clean → normal route. Ready-flip held until the gate jobs converge.
