fix(quota): record main-login responses under the observed main credential - #6830
Conversation
…ntial (#6800) Upstream quota headers were recorded only for pool and main-pool auth contexts, so a request served with the main login as a plain main context (the caller's own ChatGPT bearer, or the stored main substituted for an admission bearer) never refreshed __main__ in codex-quota-cache.json while pool rows refreshed on every response. Materialization now captures a process-local dispatch proof when the bearer actually sent upstream is the main credential the proxy already observed from its own read. HTTP delivery and the WebSocket observer record the response headers under __main__ only if that proof is still live (same identity and credential generation) at write time, and only for the canonical OpenAI forward provider. Pool health, failover and quarantine are unchanged.

When an upstream-rewriter plugin is enabled, this proof describes the headers before the physical send rather than the credential actually dispatched. sendWithConnectionPolicy subsequently calls rewriteUpstream, whose plugin contract permits replacing the URL and changing authorization or chatgpt-account-id; the WebSocket dial has the same rewrite facility. A plugin that swaps either the destination or credential therefore leaves this proof live, allowing quota headers from a non-main dispatch to update __main__ and potentially trigger its hard lock. Capture or revalidate the proof against the post-rewrite destination and headers at the physical dispatch boundary, and bind the HTTP/WS observer to that result.

Fence main quota dispatches on the current configuration generation.
When the canonical OpenAI provider is active, __main__ remains a live quota account. A configuration reconciliation can advance the generation after dispatch capture. isMainQuotaDispatchLive still approves the dispatch because it checks only identity and credential generations. The quota writer then accepts the old generation for this live account and commits the delayed response-derived snapshot under __main__.

…refusals Review follow-up for #6800: - the dispatch proof also captures the process-wide credential mutation epoch, so a native refresh or same-account reauth commit between dispatch and response drops the main quota update; - a WebSocket exchange publishes plain-main quota only through its observer; the HTTP path skips WS upstream responses and precommit refusal projections, whose headers replay the prelude snapshot; - the async materializer clears a reused context's proof before Reserve delegation.
…cation Review follow-up for #6800: a pre-response 502/504 from a WebSocket exchange carries the prelude snapshot just like a precommit refusal, so delivery could replay stale main quota over a newer reading. Both projections now carry one prelude-projection marker that the plain-main HTTP branch skips; real HTTP fallbacks after a failed upgrade still publish.
Review follow-up for #6800: response wrappers such as the combo stream preflight replace the committed WebSocket Response, so a response-object marker cannot be the only guard. The plain-main WS observer now claims its dispatch before publishing, and HTTP delivery skips any claimed dispatch. A real HTTP fallback that never saw a WebSocket quota frame still publishes.

Assert the exchange response before delivery.
quotaResponse() creates a separate, unmarked Response, so the assertion at tests/responses/responses-main-quota-observation.test.ts:381 does not test the response returned by codexWsExchange. Assert the prelude marker on refusal before deliver. Keep the expected value as true: the exchange must mark refusal responses before returning them. The later assertion alone would not detect a regression that moves this marking into delivery.

Review follow-up for #6800: the ambiguous-reset HTTP replacement reused the dispatch a failed WebSocket attempt had already claimed, so its fresh quota could not publish. The replacement now renews the dispatch into a new, unclaimed object that copies every captured fence unchanged; the failed attempt keeps the claimed one.
Review follow-up for #6800: a recovery send after a failed WebSocket attempt reused the dispatch that attempt had claimed, suppressing fresh HTTP evidence. Each plain-main WebSocket observer now renews the context's dispatch into its own copy and closes over it, so ownership belongs to one physical attempt while every captured credential fence stays unchanged.

Delivery now captures the arrival proof before its first await and uses it for the claim check, the liveness re-check and the write.

Summary
Fixes #6800. With the main ChatGPT login,
__main__incodex-quota-cache.jsonstopped updating during normal traffic while pool accounts refreshed on every response. Quota headers from upstream responses were recorded only forpoolandmain-poolauth contexts. A request served with the main login as a plainmaincontext never recorded its headers. That covers both the caller's own Codex bearer and the stored main credential substituted for an admission bearer.__main__kept whatever the last WHAM probe saw.The fix records those headers only when it is safe to attribute them to the main account:
matchesMainQuotaCredential). Identity never comes from request claims. A caller credential for another account, or the same account under another workspace, gets no proof.__main__only if the proof is still live when the response arrives. Live means the same identity generation and the same credential generation, so token rotation, credential replacement and A→B→A changes are rejected. HTTP re-checks after its awaited import. The WebSocket observer captures the proof once and re-checks it per frame.__main__; a customopenai-responsesprovider pointed elsewhere never does.usesCodexForwardPoolAuthis unchanged, so pool health, failover and quarantine do not apply to caller-owned requests. Nothing credential-derived is persisted.Out-of-range header values follow the existing consumer contract shared with
main-pool: the display reading is clamped, and policy evidence is withheld.Plan and audit record:
devlog/_plan/261009_n4_responses_quota/020_main_quota_observation.md, which lands with #6829.Verification
