Membership in this set does not guarantee that the previous upstream conversation can be addressed after local state is missing. Kiro is still rejected later in core.ts with invalid_request_error, which Codex does not handle by replaying its history; a headerless Responses request to Cursor falls back to a newly generated conversation ID; and Devin's cascadeIds map belongs to an adapter instance newly constructed for each request, so it also allocates a fresh ID. Consequently Cursor and Devin can still send only the latest delta while Kiro terminates the resumed task. Exempt these wires only when a usable provider continuation or stable client-thread identity is actually available; otherwise return previous_response_not_found.
Useful? React with 👍 / 👎.

For a noncanonical openai-responses provider configured with authMode: "forward", this branch considers a replay miss safe unless statelessResponses is set. However, createResponsesPassthroughAdapter unconditionally calls stripPreviousResponseId when forward is true, so the destination receives neither the missing response ID nor the omitted history—only the current delta. Include forward-auth routes in this refusal predicate, or preserve the ID for destinations that genuinely support it.

Qualify the 24-hour retention statement.
RESPONSE_TTL_MS defines the maximum age. Existing storage limits and eviction policies can remove replay state earlier. The current wording incorrectly guarantees 24-hour retention and successful resumption after an ordinary idle gap.

…y misses A Codex client chained by previous_response_id sends only the new turn and expects the proxy to hold everything before it. When local replay state was gone, a routed destination received that delta alone under a normal 200: the conversation was replaced by one user line with nothing reporting it. Only the canonical ChatGPT forward route and stateless Responses destinations failed closed. Refuse with previous_response_not_found for every destination that cannot see the omitted prefix, so the client resends complete history. That is every destination except the native Responses passthrough, which forwards the id to a backend that stored the chain. The three wires that look stateful do not qualify, and continuation-ownership.ts records why: devin re-sends the whole conversation each turn, cursor reads its checkpointRef out of the same expired store and otherwise falls back to full-replay, and kiro rebuilds conversationState.history from the turns it was handed. This also replaces kiro's former invalid_request_error, which told the client to start a new session and so skipped the recovery Codex performs on the structured code. Retention moves from 1 hour to 24 hours so an ordinary idle gap resumes by expansion instead of a replay round trip. The store is already bounded by its resident cap, spill ceiling and entry count, all oldest-first, so this shifts eviction from the clock to those budgets rather than raising them.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Describe replay retention as a maximum age in both guides.
RESPONSE_TTL_MS allows retention for 24 hours, but pruneResponses and enforceSpilledResponseBudget() can evict state earlier when entry, memory, or disk ceilings apply. The current English wording, “retained for 24 hours,” and Korean wording, “24시간 보존하며,” can imply a guaranteed 24-hour retention period.
At docs-site/src/content/docs/guides/codex-integration.md:368-369, state that replayed state is retained for up to 24 hours and may be evicted earlier by the memory, disk, or entry ceilings. Apply the equivalent wording at docs-site/src/content/docs/ko/guides/codex-integration.md:209-210.

Neither is in any of the twelve god-file decompositions the audit spent most of its budget on. The generic-OAuth 429 ladder reserves a hop before it knows whether a rotation is possible, and the reservation is the charge. Its two explicit early-outs released the permit; its catch did not, so a throw from the snapshot fetch or from credential application spent an allowance on a send that never left the process, and a later recovery in the same request was refused because of it. adapter-dispatch now confirms with use() immediately before the rebuild that spends the permit and releases in its catch -- release() is a no-op once used, so one catch covers both halves. adapter-continuation only releases, because its replay is the next loop iteration and confirming before continue would charge a hop that never ran. run-turn-execution already had this shape. The pool refresh cooldown is learned about a credential but keyed by account id alone, so a successful reauthentication inherited the dead credential's 15-60s quarantine: selection kept excluding an account that had just been authenticated, and with a healthy sibling the thread detoured and lost its warm cache and continuation. login-flow now clears the refresh-failure record where it replaces the credential, beside the quota and needs-reauth clears already there. Generation-fenced keying stays open and is noted. The file-size ratchet also gets its six former god-files back at their current sizes. They were dropped from the cap list when they fell under the 2,000-line threshold, which left the files the decomposition programme exists to shrink as the only ones free to grow back.
