fix(usage): bill the Codex request a compaction's counter rewind drops - #35536
Codex can rewind total_token_usage below the previous token_count snapshot without starting a
new sequence: a later turn continues from a snapshot taken earlier in the same rollout. The parser
requires cumulative - previous === last_token_usage (or an exact restart where cumulative === last), so that snapshot is counted as malformed and the request it reports is
dropped. Usage then shows "N malformed or inconsistent usage record(s) were skipped", and the
dropped request is missing from the totals and cost estimate.
This is the case reported in #29363. #22376 / #22558 fixed counters that restart at the request
itself (cumulative === last); this change covers the same rewind where the cumulative total stays
above last_token_usage but below the previous snapshot. No issue was filed for the two sessions
below before I found #29363.
Change
apps/server/src/provider/Drivers/codexUsage.ts: add isRewoundBaseline beside the existing
fresh-counter branch. A rewind becomes the new baseline and bills its request only when the
timestamp did not go back, the cumulative total went back, and every component still covers last_token_usage. Otherwise the existing duplicate, cumulative-delta and unreported-request checks
run unchanged. The last cumulative timestamp is kept in scan state (optional, so older cached scan
states stay valid).
apps/server/src/usage/usageScanCache.ts: bump USAGE_SCAN_CACHE_VERSION to 15 so cached Codex
entries with malformedRecords > 0 re-parse once and pick the dropped request up. Entries with no
malformed records stay warm.
Scope
Fixes#29363. One parser bug and the cache bump it needs to repair existing scans; no behavior change
outside Codex token_count handling.
Verification
Real sessions (both event_msg / token_count lines; each snapshot still contains the request it
reports, but the counter is below the previous snapshot):
2026-08-31T16:29:23.990Z, previous snapshot 47,762,208 total, rewinds to 29,451,231 and reports
222,335: a compacted event follows two minutes later.
In both files the next token_count reconciles against the rewound baseline (e.g.
3,699,551 - 3,621,978 = 77,573 = last). End to end over both rollouts: 0 malformed records and
exactly 299,669 more tokens than before (222,335 + 77,334); every other record parses identically.
Tests:
codexUsage.test.ts: both real snapshots plus their next event, a second rewind in the same
session, a rescan of the same lines, [Bug]: Codex usage skips a request whose cumulative counters rewind to an earlier snapshot #29363's synthetic fixture (four requests, 1,910 tokens, no
skipped record), a snapshot that does not contain its request, and a stale snapshot whose
timestamp goes back. Rewind tests fail without the new branch and pass with it.
usageScanCache.test.ts: a v14 entry with malformedRecords: 1 re-parses; the repaired entry
written under the current version keeps its position.
UsageService.test.ts: a warm v11 cache left with one dropped request by the old parser is
repaired on the first run (3 records, 27 output tokens, 0 malformed), and the repaired cache is
reused on the next start without reading the file.
Three tests in UsageService.test.ts fail on clean main (63d5c6d) on macOS before and after this
change, for reasons unrelated to it:
discovers Pi history in its default home and directory overrides and returns other providers' usage while Muse home discovery is still pending compare an expected /var/... path against the resolved /private/var/... path.
retains Codex reconciliation and partial coverage through persisted restart, append and repair
spies on NodeFSP.open and compares the raw path, the same /var vs /private/var mismatch.
Known limitation: a delayed replay of an older normal snapshot that carries a fresh timestamp is
indistinguishable from a rewind in the fields Codex writes, so it is billed again. Today that record
is dropped as malformed instead. Exact duplicates and restart-shaped replays are unaffected.
Fixtures contain only token counters and timestamps; no session IDs, paths or transcripts.
Model: github-copilot/auto. Harness: T3 Code through OpenCode.
Replaying an older restart snapshot can emit the same usage again, causing duplicate billing. rebaseCodexUsage advances lastCumulativeTimestampMs before the replay check, but the restart-replay branch restores only lastCumulativeUsage, so the counter baseline and timestamp no longer describe the same snapshot and the next old snapshot passes the rewind guard. Restore lastCumulativeTimestampMs alongside the counters when ignoring the replay.

Macroscope's review found this PR requires human approval — This restores Codex requests omitted after counter rewinds and refreshes affected cached usage. An unresolved finding reports that restart replays can instead duplicate usage accounting; that replay-handling concern needs resolution.

Codex rewinds total_token_usage when compaction rewrites a long session's
history. The cumulative-delta check treated the snapshot that carries the
rewind as malformed and dropped the request it reports, so Usage showed
"N malformed or inconsistent usage record(s) were skipped" and lost one
request per rewind.
A rewind whose snapshot still contains the request (cumulative total went
back, every component covers last_token_usage, timestamp did not go back)
now becomes the new baseline and bills that request once. Duplicates,
snapshots behind their request, and stale records keep failing the
existing checks.
Bump the scan cache version so Codex entries that cached malformedRecords
re-parse once; clean entries stay warm.
No actionable comments were generated in the recent review.
Walkthrough
Codex usage scanning now tracks cumulative snapshot timestamps and accepts qualifying counter rewinds as new baselines. The scan cache advances to version 15 and marks eligible malformed version 14 Codex entries for a cold rescan.
The parser tracks the latest cumulative snapshot timestamp. It accepts a lower cumulative baseline when its timestamp is not older and each counter covers the reported request. Tests cover billing across rewinds, restart replays, rejected snapshots, and discarded pending requests.
The cache advances to version 15 and retains version 14 as a legacy input. Version 14 Codex entries with malformed records are marked for a cold rescan. Tests verify that malformed entries are reset and clean entries remain cached.
The change now bills Codex requests dropped by counter rewinds. The earlier risks of double-billing from stale or replayed snapshots and of silently lost pending usage appear addressed, so no actionable merge-blocking risk remains.

Explanation
Directly linked issue #29363 requires three coding outcomes. (1) A Codex snapshot whose cumulative total falls below the previous snapshot, but still contains its reported request, must bill that request. (2) Later requests must reconcile against the lower baseline. (3) The synthetic rollout must yield 1,910 tokens with no skipped-record warning.
The reviewed head adds isRewoundBaseline in codexUsage.ts. It accepts a rewind only when a prior baseline and prior timestamp exist, the snapshot timestamp did not go back, the cumulative total decreased, and every component covers last_token_usage. The previous review traced the issue's third snapshot (total 1,670 to 1,560, request 240, timestamp 12:00 after stored 10:00:02) through this branch. It bills the request and rebases to 1,560. Later snapshots reconcile against that baseline. The author reports codexUsage.test.ts coverage of the synthetic fixture (four requests, 1,910 tokens, no skipped record).
Since the previous review, the head changed to restore the baseline timestamp on restart-replay paths and to count unreported pending anonymous requests as malformed when a rewind is accepted. These changes are described in the summary and commit messages. I did not open the changed hunks for this review. The #29363 synthetic case has no pending anonymous requests, so the pending-request change does not alter its expected result. The reported test results support the verdict, but the head delta itself rests on the summary.
The fresh-timestamp replay limitation in the PR description is not a #29363 requirement.
Full details: Out of Scope Changes check
Explanation
Changes from the merge base are limited to Codex token_count handling and usage scan cache repair:
(a) codexUsage.ts: the isRewoundBaseline branch, the optional lastCumulativeTimestampMs field in scan state, timestamp advancement on rebase, fork-copy, request-ledger and restart-replay paths, and malformed-marking of unreported pending requests when a rewind is accepted. These serve the counter-rewind case in #29363 and the replay handling raised in review.
(b) codexUsage.test.ts, usageScanCache.test.ts and UsageService.test.ts: tests for the rewind, stale timestamps, cache repair and the v15 cache file name. These verify the change.
(c) usageScanCache.ts: USAGE_SCAN_CACHE_VERSION and SCAN_CACHE_FILE_NAME move to 15, v14 is kept as a legacy filename, and v14 Codex entries with malformedRecords > 0 are rescanned. The cached warning in #29363 persists until re-parse, so this bump is needed for the fix to reach existing scans. Clean entries stay warm.
No change unrelated to Codex token_count handling or cache repair was found in the summarized paths. The three macOS /var versus /private/var test failures are reported as pre-existing on main and are not caused by this change.

Advance the timestamp when advancing legacy counters.
Legacy requests update lastCumulativeUsage here but leave its new timestamp field unchanged. This allows a cumulative re-emission to bill an already counted request.
For example, use zero cached and reasoning counters:
Establish cumulative (100,20) at t1.
Bill legacy (20,4) at t2.
Bill legacy (30,6) at t3.
Re-emit the t2 request with cumulative (120,24).
The current baseline is (150,30), but its timestamp remains t1. The re-emission therefore passes the rewind check and emits the same 24 tokens again.
Update the timestamp alongside legacy counter advances. Apply the same synchronization to the fork-copy advance path at Line 295. Add this sequence to the legacy/cumulative reconciliation coverage.

Ignoring a replay of the sequence's first request restored the cumulative
counters but left the replay's older timestamp, so a later stale snapshot
passed the rewind guard and billed its request again. Restore both.
Drop the rescan and service-level cache tests: the parser and decode-rule
tests already fail for those regressions.
AI-assisted; verified with the tests and tools listed above.
A rejected stale snapshot rebased the timestamp backward, and a billed
last-only request advanced the counters but not their timestamp. Either
let a later stale snapshot pass as a rewind and bill usage again. Keep the
timestamp as a high-water mark and advance it with the legacy counters;
that also covers the restart replay, so its separate restore goes.

Scan states cached before v15 resume without lastCumulativeTimestampMs,
and the rewind guard treated that as in order, so a stale snapshot
appended after upgrade billed an already counted request. Require a known
baseline timestamp; the next snapshot records one, so caches stay warm.

Count pending anonymous usage as malformed on the rewind path.
The rewind branch at codexUsage.ts:385 returns without reading pending, which holds the anonymous token_usage_record entries. These entries are not billed, and unlike the non-rewind path at lines 386-390, they do not increment state.malformedRecords. The rewound snapshot's last is billed, so the loss of pending usage is silent.
The original comment's statement that line 339 deletes the pending entries is inaccurate. Line 69 deletes state.unreportedRequests, but the local pending at line 337 still holds the array. The defect is that the rewind branch never reads it.
The pending tokens were not billed before this change either. The previous rewind path failed as malformed. The change here is that this loss is no longer reported. Whether the pending entries should instead be billed is not established by the design, so this review does not recommend billing them.

Restore the timestamp guard before resuming a clean v14 entry.
Clean v14 entries have no lastCumulativeTimestampMs. Keeping these entries resumable makes isRewoundBaseline accept an older snapshot because its timestamp check permits undefined.
For example, cache counters (100, 20) from 10:00:10, then append a snapshot at 10:00:08 with cumulative (50, 10) and last=(20, 4). The migrated state bills 24 tokens. A cold scan rejects the same snapshot as stale. The migrated entry then persists the incorrect total without a malformed-record warning.
Restore the baseline timestamp before incremental parsing. Alternatively, keep unchanged entries warm but require a cold scan when a timestamp-less entry grows.

[major] apps/server/src/provider/Drivers/codexUsage.ts:68: Worse than main: an ignored restart replay gives a timestamp to a resumed v14 baseline whose age is unknown. The replay branch restores lastCumulativeUsage but leaves this newly assigned timestamp. A following stale snapshot passes isRewoundBaseline and double-counts usage and estimated cost. Confirmed against origin/main: replay outputs are [0,0] on main and [0,24] on this head.
Fails with: A user resumes a clean v14 Codex cache after three snapshots: t=10:00:00 last=(100 input,20 output), cumulative=(100,20); t=10:00:05 last=(20,4), cumulative=(120,24); t=10:00:10 last=(30,6), cumulative=(150,30). Other counters are zero and total_tokens=input+output. The cached state has sequenceStartSignature but no lastCumulativeTimestampMs. Append exact replays of the first and second snapshots. The first is ignored but installs 10:00:00 as the timestamp for retained cumulative=(150,30); the second incorrectly emits its already-counted 24 tokens.
…estamp
The restart-replay branch restored the cumulative counters but kept the
timestamp the replay had just installed. For a warm v14 cache with no baseline
timestamp, replaying the first snapshot gave the newer counters an older time,
so replaying the second snapshot passed the rewind guard and billed 24 tokens
again. The replay now restores the timestamp too, removing the field when the
baseline had none.
An accepted counter rewind also discarded pending anonymous requests without a
warning. Requests the rewound snapshot does not report now count as malformed
records and stay unbilled.

This looks like a duplicate of #29366 (opened 2026-11-02), which also fixes #29363.
Both PRs change the same reconciliation in apps/server/src/provider/Drivers/codexUsage.ts: when a cumulative snapshot falls below the previous baseline, they treat it as a rewind, add a last-snapshot timestamp to the scan state to tell a rewind from a stale record, and bump usageScanCache.ts so cached scans are re-parsed. #29366 also updates UsageService.ts, and it already has a maintainer takeover and before/after evidence on it.

Problem
Codex can rewind
total_token_usagebelow the previoustoken_countsnapshot without starting anew sequence: a later turn continues from a snapshot taken earlier in the same rollout. The parser
requires

This is the case reported in #29363. #22376 / #22558 fixed counters that restart at the request
