fix(server): replayed Claude wake no longer resurrects expired usage limits - #36592
Claude can emit a rejected background wake while no T3 turn is active. T3 buffers that wake's 429 frames; after the limit resets and a later turn completes normally, replaying those old frames incorrectly fails the queued continuation as usage-limited again, with a reset timestamp already in the past. The continuation makes no new upstream request.
Fix
In the existing Claude adapter replay path:
Identify a buffered 429 result and its corresponding rejected-rate-limit frames. Prefer the standalone rate_limit_event reset over a conflicting embedded assistant reset.
Only treat the rejection as expired when the result arrived before its reported reset and replay happens at or after that reset. A new 429 arriving after an old advertised reset is still a real rejection. Unavailable or future resets follow existing handling.
Suppress the obsolete rate-limit/assistant frames when replaying that expired failure, settle the stale continuation as completed, and retain the buffered result for token-usage accounting. Leave unrelated buffered frames and real active-limit handling alone.
No contract, authentication, provider-selection, or client changes. The fix stays inside the Claude backend adapter and its existing test file.
Reproduction and verification
Red on original main: The regression from the issue replays an old buffered rejection after reset; the continuation finishes failed instead of completed (expected 'completed', received 'failed'). A second red case caught an unsafe initial implementation that hid a fresh 429 arriving after its stated reset.
Green with the correction: The existing background-wake test table now covers 18 cases: standalone vs. embedded reset reporting, an intervening successful turn, a fresh 429 that must remain a failure, a separate still-active seven-day limit alongside an expired five-hour limit, two expired buffered wakes, an earlier expired wake followed by a genuinely active later wake, and four overage-allowed metadata cases (all three supported overage indicators plus an embedded-only 429). Expired cases assert no stale usage-limit notice and retain nonzero token accounting. The two-wake regression failed before the follow-up correction (an obsolete usage-limit notice survived) and passes afterward. The four overage cases also failed before the follow-up correction and now pass; overage-allowed metadata does not prevent expiry of an independent exhausted window, while an embedded-only 429 remains a real failure when no blocking reset is available. The newest regression also fails on the previous PR head when an expired 429 is replayed while a newer root wake is still running. The correction leaves that root active, settles it only on its own result, and carries forward the old 429 result's token and ledger usage. Tests cover this both with and without an intervening empty task-lifecycle result. A further red-green review pass confirmed that an absorbed newer root must settle immediately (even with that empty lifecycle result), and that every expired buffered result's billed usage is retained exactly once. Three new regression rows cover these scenarios, including distinct token counts across two expired wakes and a final active root.
After incorporating the maintainer's commits (including the independent active-limit fix) and fetching the current upstream base, vp run check:changed --concurrency 2 passed formatting, lint, both Knip checks, GraphQL generation check, typechecking 3 affected packages, and 434 selected tests across 2 files. git diff --check is clean.
Related work:#22998 also changes Claude's replay settlement, but targets older buffered results settling newer wakes. This fix addresses a rejected wake replayed after its quota reset. That PR is currently labelled needs-rebase and touches the same adapter; if it lands first, this branch will need an integration rebase and regression rerun. No unrelated changes from it are included here.
Limit: Validation uses deterministic Claude SDK frames and Effect's test clock; I did not run an authenticated live Claude subscription session or assert screen-reader/browser behavior (the change is server-only).

Macroscope's review found this PR approvable — Claude wake replay now discards explicitly expired rate-limit rejections instead of restoring stale errors, while retaining usage accounting. Live or unknown-reset limits keep their existing handling, and the change is confined to buffered replay.

Claude wake replay now detects buffered rate-limit rejections whose reset times have passed. It skips expired frames and completes eligible continuations while retaining results for usage accounting. Tests cover reset timing, intervening turns, weekly limits, overage indicators, and multiple wakes.
The adapter checks buffered 429 results for rejected rate-limit evidence with finite, positive reset times that fall after result arrival and at or before replay.

Replay skips expired rejection frames and completes eligible continuations with results retained for usage accounting. Tests cover reset timing, intervening turns, weekly limits, overage indicators, and multiple wakes.
Replay of an expired Claude wake no longer surfaces a stale usage-limit failure in the common case. In one edge case, where a later user turn absorbs a still-open wake, the continuation can stay active indefinitely. Token usage from earlier expired wakes can also be under-reported. Fix the absorbed-root completion before merging.

Explanation
The title names the primary change: replayed Claude wake no longer resurrects expired usage limits. It matches the changeset summary, which suppresses expired 429 frames during buffered-wake replay. It follows the conventional commit form and uses plain language. It omits detail such as overage handling, but that detail is not required.
Full details: Linked Issues check
Explanation
[#36405] requires that a buffered Claude wake rejection, whose reset has passed by replay time, does not fail the queued continuation as a usage limit and does not restore the limited state. The reviewed adapter change in ClaudeAdapterV2.ts adds expiry detection for buffered 429 results. A result counts as expired only when every applicable blocking reset is finite, positive, later than the frame arrival time, and at or before replay time. Standalone rate_limit_event resets take precedence over embedded assistant resets for the same limit type. During replay, the expired rejected rate_limit_event and blocked assistant frames are skipped. The expired continuation settles as completed, and the buffered result is kept for token-usage accounting. This matches the issue timeline. The 429 arrived at 20:41 UTC, and the reset was after that time and before the replay at 21:31 UTC, so the expiry condition holds. A fresh rejection that arrives before its reset keeps existing failure handling. The test file (ClaudeAdapterV2.test.ts, +262/-21 per the change summary) was not read directly. Its coverage is established only from the change summary and PR description, so the test evidence is not independently confirmed here.
Full details: Out of Scope Changes check
Explanation
The changes in ClaudeAdapterV2.ts are limited to the buffered-wake expiry helper, its call site in the replay path, and the completed-settlement handling for expired selected results. Each branch serves the #36405 scenario. Active-limit handling for non-expired results is described as unchanged. The PR description and change summary report no changes to contracts, authentication, provider selection, or clients. The test file changes are described as a scenario matrix for the same wake-rate-limit path. The test file diff was not read directly, so its content was not independently checked for unrelated edits. This does not show a concrete out-of-scope change.
Full details: Description check
Explanation
The description covers the problem, the fix, scope, and verification, and it links the issue (#36405). The Problem and Change sections follow the template. The Verification section is detailed, with red-green results, check results, and a stated limitation. The Scope section links the issue, and the bug-fix scope is clear. The model/harness line is present as the template asks. Minor gaps: the description is long and includes a related-work section, and it does not clearly state the test-count discrepancy with the objectives (13 vs 18 cases; 429 vs 434 tests), which reviewers may want reconciled. The template's 'one underlying problem' guidance appears satisfied, since the fix addresses one replay bug.

Keep the expired buffered rejection from failing the continuation while a newer root turn is open.
When lastResultExpired and newerRootStillOpen are both true, the expired-result branch is skipped. The next branch then calls handleSdkMessage with the expired 429 lastResult. When the result is not gated, it reaches the result path, where terminalStatusFromResult returns "failed" for a 429 success result. The continuation can then finalize as failed with a usage-limit failure, which the expired-result branch is meant to prevent.
The gate at lines 11540-11600 can drop or re-buffer the result when the prompt echo is unconfirmed. The failure therefore depends on the echo state. The non-expired dispatch at this position already exists on the base revision, so this ordering predates the PR.
Define the handling for this buffered result before changing the dispatch at line 12931. Do not complete the continuation while the newer root turn is open, because the newer root frames are already dispatched into the same active context. Do not let the expired result settle the newer turn. Keep the result's usage accounting (result: lastResult), since a skipped dispatch would bypass the accounting in the result path.

Fixes #36405.
Bug
Claude can emit a rejected background wake while no T3 turn is active. T3 buffers that wake's 429 frames; after the limit resets and a later turn completes normally, replaying those old frames incorrectly fails the queued continuation as usage-limited again, with a reset timestamp already in the past. The continuation makes no new upstream request.
Fix
In the existing Claude adapter replay path:
rate_limit_eventreset over a conflicting embedded assistant reset.No contract, authentication, provider-selection, or client changes. The fix stays inside the Claude backend adapter and its existing test file.
Reproduction and verification
Red on original
main: The regression from the issue replays an old buffered rejection after reset; the continuation finishesfailedinstead ofcompleted(expected 'completed', received 'failed'). A second red case caught an unsafe initial implementation that hid a fresh 429 arriving after its stated reset.Green with the correction: The existing background-wake test table now covers 18 cases: standalone vs. embedded reset reporting, an intervening successful turn, a fresh 429 that must remain a failure, a separate still-active seven-day limit alongside an expired five-hour limit, two expired buffered wakes, an earlier expired wake followed by a genuinely active later wake, and four overage-allowed metadata cases (all three supported overage indicators plus an embedded-only 429). Expired cases assert no stale usage-limit notice and retain nonzero token accounting. The two-wake regression failed before the follow-up correction (an obsolete usage-limit notice survived) and passes afterward. The four overage cases also failed before the follow-up correction and now pass; overage-allowed metadata does not prevent expiry of an independent exhausted window, while an embedded-only 429 remains a real failure when no blocking reset is available. The newest regression also fails on the previous PR head when an expired 429 is replayed while a newer root wake is still running. The correction leaves that root active, settles it only on its own result, and carries forward the old 429 result's token and ledger usage. Tests cover this both with and without an intervening empty task-lifecycle result. A further red-green review pass confirmed that an absorbed newer root must settle immediately (even with that empty lifecycle result), and that every expired buffered result's billed usage is retained exactly once. Three new regression rows cover these scenarios, including distinct token counts across two expired wakes and a final active root.
