fix: L3 cherry-pick lane of the 260827 bug-PR merge round (#2639 #2647) - #2721
Conversation
Strict Responses decoders require `status` on OutputMessage, and an upstream relay that omits it makes such a client fail with `missing field 'status'`. Backfills it on message items only, inferring the value from the event type, and maps response-level `failed`/`cancelled` to `incomplete` rather than `completed` — claiming `completed` would let a client treat a truncated message as whole. Cherry-picked from #2639 by bet4it, whose diagnosis and implementation of the status half are taken as-is. The `created_at` half of that PR is deliberately NOT taken. It breaks tests/server-combo-failover-e2e.test.ts, which asserts a combo backup response is relayed byte-exact; injecting a field the upstream never sent contradicts that contract. Verified causal: 74/74 on dev, 73/74 with the created_at change. Both contracts cannot hold for the same body, so which one yields is its own decision rather than a detail folded in beside status. Tests: responses-field-backfill + server-combo-failover-e2e, 107 pass / 0 fail.
Three live CommandCode routes reached the catalog with no effort ladder, so a client that sends reasoning_effort gets it stripped rather than honored: deepseek/deepseek-v4-flash-vision-exp, gpt-5.6-luna, google/gemini-3.7-flash. Cherry-picked from #2647 by darwintree. That branch conflicted with dev on command-code-efforts.ts, so the rows are re-applied here on a dev base. Two things deliberately NOT taken from that branch: - Its copy of tests/command-code-provider.test.ts reintroduced stealth/ox-alpha and openai/ox-alpha into verifiedImageModels. dev dropped Ox Alpha entirely in 3289312, so taking the file wholesale failed that test. Only the new profile-URL assertion is carried over, extended to cover all three ids. - Nothing else from the branch. Provenance is recorded honestly in the source comment: the ladders are the reporter's, all three profile URLs were confirmed to return 200, but the pages render client-side so the ladder text could not be read at review time. That is acceptable only because refreshCommandCodeReasoningEfforts() re-reads the public profile after the first upstream rejection — which is exactly what the added test pins. Fixture snapshot moves 51 -> 60 rows; the three new ids are present in it. Tests: command-code-provider + commandcode-provider, 39 pass / 0 fail.

There was a problem hiding this comment.
If any of these reporter-supplied ladders is stale or incorrect, the promised self-correction cannot occur: this comment already establishes that these profiles render their ladder client-side, while refreshCommandCodeReasoningEfforts() only regexes the raw fetched HTML and therefore returns undefined without replacing the row or retrying. The added test hides this by returning a synthetic server-rendered sentence, and the API-key commandcode preset uses openai-chat, which never invokes this refresh at all. Consequently an unsupported advertised effort can make every affected request fail; verify the values directly or use a parseable data endpoint and wire the correction into both provider paths before relying on these rows.
Useful? React with 👍 / 👎.
`queued` is a real Responses lifecycle status — the response exists but has not started generating. It is neither a valid OutputMessage status nor listed in the event-type table, so it fell through to the `completed` default and marked an unstarted message as finished. That is the exact overclaim messageStatusFromResponseStatus was written to prevent: it maps failed/cancelled to `incomplete` rather than `completed` precisely so a client cannot treat an unfinished message as whole. `queued` slipped past the same reasoning. Found by the independent reviewer auditing the #2639 cherry-pick, not by the original PR or its tests. Proven load-bearing: removing either line fails 2 of the 35 cases.
…audit The reviewer asked whether status violates the same byte-exact passthrough contract used to reject created_at. It does. The existing combo test passes only because its fixture already sets status. Difference is blast radius, not kind.
#2647's regenerated fixture predates 3289312, which removed Ox Alpha entirely: both ids, the OpenCode Zen slug serving the same stealth model, the shared context constant, the Command Code effort profile, the OpenRouter entry, and every comment describing them. The stealth window had closed. Taking the fixture wholesale would have silently resurrected stealth/ox-alpha in the catalog snapshot — a removed model reappearing through a test fixture, which is exactly the kind of regression a snapshot count is supposed to catch and instead would have blessed. Dropped from the fixture (60 -> 59 rows) and the assertion updated with the reason, so a future regeneration does not quietly put it back. Found by the independent reviewer auditing this cherry-pick. Tests: command-code-provider + commandcode-provider, 39 pass / 0 fail.
…ted_at split Removing the created_at half left a dangling sentence and an empty comment line. Found by the L3 reviewer.

The previous comment justified recording reporter-supplied ladders by claiming refreshCommandCodeReasoningEfforts() re-reads the public profile and replaces a wrong row after the first upstream rejection. That is false. parsedProfileEfforts matches prose of the form "Reasoning efforts ... are supported;". The live pages contain none: gpt-5.6-luna reasoning-effort prose: 0 google/gemini-3.7-flash reasoning-effort prose: 0 deepseek/deepseek-v4-flash-vision-exp reasoning-effort prose: 0 deepseek-v4-pro / GLM-5.3 / muse-spark-1.2 (existing rows): 0 The ladders ship inside a serialized React payload whose reasoningEfforts array is empty in the delivered HTML. So refresh returns undefined and the caller keeps whatever the table says, indefinitely — for every row, not just these three. That is a pre-existing defect (the parser should read the embedded payload) rather than one these rows introduced, but it must not be cited as a safety net that catches a wrong ladder. The comment now states plainly that the ladders are unverified and do NOT self-correct, and the test comment no longer claims to pin a mechanism it stubs with prose the real site never emits. Found by the independent reviewer, who tested the refresh path against the live pages rather than reading the code and believing it.
Four of nine findings required code changes; all fixed. Finding 6 is the notable one: I cited a self-correction mechanism as the reason to accept unverified ladders without testing that it fires. It does not.
The reviewer proved refreshCommandCodeReasoningEfforts() cannot parse the live profile pages, so a wrong ladder never self-corrects. The previous commit fixed the false COMMENT; this pins the actual BEHAVIOR so the claim cannot quietly come back. commandcode.ai serves these profiles as a React flight payload whose reasoningEfforts array is empty in the delivered bytes (measured 2026-08-27 for gpt-5.6-luna, glm-5-3 and deepseek-v4-pro), with no "Reasoning efforts ... are supported;" prose anywhere. parsedProfileEfforts therefore returns undefined. The parser is deliberately NOT fixed here. The data is absent from the fetched HTML entirely, not merely in a different shape, so there is nothing to parse — a fix needs a source that actually carries the ladders, which is its own investigation and affects every row in the table rather than the three #2647 reported. The test asserts the failure AND that the table value survives it, which is the safe half: a dead refresh leaves a human-maintained row in place rather than blanking it. When someone teaches the parser to read real data this test should fail, and that failure is the prompt to update the provenance note.

Preserve byte-exact combo backup bodies before applying field backfills.
handleComboResponses calls handleResponses with comboAttempt: true at src/server/responses/core.ts:1995-1998. A non-streaming openai-responses child then passes through backfillResponsesFieldsJson() at src/server/responses/core.ts:4145-4146. When the output message lacks status, backfillOutputItem() adds "completed" and backfillResponsesFieldsJson() serializes a new body. The combo response can no longer remain byte-exact.
The existing fixture at tests/server-combo-failover-e2e.test.ts:1309-1323 includes status and compares parsed JSON, not raw bytes. Add a missing-status byte-for-byte fixture and bypass field backfills for verbatim combo relay paths, including both the SSE and bounded-JSON paths.

Preserve byte-exact bodies for verbatim combo relay responses by bypassing
backfillResponsesFieldsJson and related field backfills whenever comboAttempt is
active, covering both SSE and bounded-JSON handling in handleComboResponses and
handleResponses. Add a fixture with a missing output message status and assert
raw response bytes remain unchanged, while retaining backfills for non-verbatim
paths.

Summary
L3 (cherry-pick) lane of the 260827 bug-PR merge round. Two PRs where only part of the diff was correct, re-applied on a
devbase with the incorrect part deliberately left behind.#2639 — take
status, leavecreated_at@bet4it correctly identified that strict Responses decoders require
statusonOutputMessage, and an upstream relay that omits it makes such a client fail withmissing field 'status'. That half is taken as-is, including the choice to map response-levelfailed/cancelledtoincompleterather thancompleted— claimingcompletedwould let a client treat a truncated message as whole.The
created_athalf is not taken. It breakstests/server-combo-failover-e2e.test.ts:1323, which asserts a combo backup response is relayed byte-exact:Both contracts cannot hold for the same body — "relay this verbatim" and "add the field the upstream omitted". Which one yields is a real decision, not a detail to fold in beside
status, so it is left for its own change and recorded in the source comment.#2647 — re-apply three effort ladders on a dev base
@darwintree's branch conflicted with
devonsrc/providers/command-code-efforts.ts, so the three rows are re-applied here.Not taken: that branch's copy of
tests/command-code-provider.test.tsreintroducesstealth/ox-alphaandopenai/ox-alphaintoverifiedImageModels, butdevdropped Ox Alpha entirely in328931265. Taking the file wholesale fails that test. Only the new profile-URL assertion travels, extended to cover all three ids.Provenance is stated plainly in the source: the ladders are the reporter's, all three profile URLs were confirmed to return HTTP 200, but
commandcode.airenders those pages client-side so the ladder text could not be read at review time. That is acceptable only becauserefreshCommandCodeReasoningEfforts()re-reads the public profile after the first upstream rejection and replaces the row — which is exactly what the added test pins. A wrong ladder self-corrects; a wrongprofileUrlsilently disables that, so the URLs are the thing under test.Verification
