The brief required no change at 8182aed, but the branch had already moved to 7788717 (the v16 cache bump and keeping the baseline when an older snapshot is rejected), and CodeRabbit had one open Major finding on that commit: a rejected snapshot stamped with the baseline's own time and lower counters still replaced the baseline, so the replay of the next snapshot reconciled against it and was billed again. The finding was right; I added its sequence as a row in the existing regression table and it failed (36 tokens billed on the replay). Commit be9b8f6 fixes it in codexUsage.ts: a rejected snapshot is now treated as a replay, leaving the baseline and pending anonymous requests untouched, when it is older than the baseline or when it has the baseline's time with lower, non-zero counters. I did not apply CodeRabbit's suggested plain <=: it broke two existing tests where a same-time snapshot legitimately becomes the next baseline (an inconsistent pair whose counters advance, and a malformed pair that resets the counters to zero), so the equal-time case is narrowed to lowered non-zero counters. After the push all checks on be9b8f6 passed, Macroscope approved at be9b8f6, and CodeRabbit marked both of its Major findings as addressed and raised nothing new. No merge with main was needed (the pull request was mergeable and clean).

Supersedes #35536. The change is @rihanaws's; their commits are kept.

Reproduction on main

Not executed. In an isolated environment, create a synthetic Codex rollout under its configured sessions directory with session metadata and a model turn context. Use zero cached, cache-write and reasoning counters, and total_tokens=input+output throughout. Add a token_count at 10:00:00 with last and cumulative both (100 input,20 output); anonymous token_usage_record entries at 10:00:05 for (40,8) and 10:00:06 for (20,4); then a token_count at 10:00:07 with last=(20,4), cumulative=(60,12), followed at 10:00:08 by last=(10,2), cumulative=(70,14). Open Usage for that environment and date. Both versions count 156 tokens, but main silently loses the pending 48-token request; this PR reports one skipped malformed or inconsistent record.

Evidence

Proven in the real web app, Chromium 1280×800, light theme, fresh databases and synthetic provider data.

Steps: seed the last-only guard, bridged-request guard, rejected-baseline replay, and grown-v15-cache cases; open Usage → Tokens and refresh. Then add the reported anonymous-request rewind rollout and refresh again. Wait for refresh completion before captures.

The four guard/cache cases total 828 tokens before and 720 after; each correctly bills 180 after. Adding the reported rollout contributes 156 tokens on both sides. Its discarded request leaves the base warning count unchanged at 1, while head increases from 4 to 5. Final totals are 984 before and 876 after.

Timestamp and cache overview Before: 828 tokens and one skipped record After: 720 tokens and four skipped records

After adding the discarded anonymous request Before: 984 tokens, warning count remains one After: 876 tokens, warning count increases to five

Scenario and synthetic seed · Before recording · After recording

Tests

In apps/server: vp test run src/provider/Drivers/codexUsage.test.ts failed on the new equal-timestamp row before the fix (expected 0, billed 36) and passed after. vp test run src/provider/Drivers/codexUsage.test.ts src/usage: 9 files, 233 tests passed. vp run check:changed: format, lint, knip, graphql, typecheck (3 packages) and tests (4 files, 120 tests) all passed. CI on be9b8f6: all 8 required checks passed, no failing check runs.

Not in this change

  • Anonymous requests pending when the counters restart at the request itself (cumulative equals last) are still dropped without a warning; only the rewind case named in the brief was changed.
  • A delayed replay of an older normal snapshot that carries a fresh timestamp is still indistinguishable from a rewind in the fields Codex writes and is billed again, as on main.
  • Scan states cached by the current v15 parser whose baseline came only from requests without cumulative counters have no baseline time; a genuine rewind right after resuming one is reported as a skipped record rather than billed. No cache bump was added for this narrow case.
  • Anonymous requests pending when the counters restart at the request itself (cumulative equals last) are still dropped without a warning; only the rewind case was changed.
  • A rejected same-time snapshot whose counters advance (not lower) still becomes the next baseline; existing tests depend on that recovery behaviour, so it was left as is.

…ter rewind

A rewind is told from a stale snapshot by comparing its time with the
baseline's. Three paths left that comparison open:

- A request billed without cumulative counters moved the baseline but
  not its time, so an older snapshot re-emitted afterwards was billed
  again. Every move of the baseline now dates it.
- A baseline of unknown age accepted any rewind, and an ignored restart
  replay gave it the replay's time. It now accepts none and stays
  undated.
- A rewound snapshot dropped the anonymous requests read before it
  without a trace. They now count as skipped records, so the usage
  warning shows.

…hen its file grows

Requests without cumulative counters used to move the baseline without
dating it, and the v15 cache resumes such a state. The parser cannot
order a later snapshot against it, so a genuine rewind after the
upgrade was skipped. The cache now serves that entry while the file is
unchanged and re-parses it whole once it grows, which dates the
baseline.

Co-Authored-By: Claude Fable 5.2 <[email protected]>
A v14 Codex entry migrates to an entry with no scan state and is saved
that way under v15. The undated-baseline check read that missing state
and threw, which stopped the whole cache from loading. An entry without
a state is now left as it was.

Approvability

Verdict: Approved at be9b8f6

Macroscope's review found this PR approvable — Corrects Codex usage reporting so older snapshots are not counted as counter rewinds, and makes skipped requests visible. The cache migration preserves historical records while reparsing incompatible incremental state; actual payment behavior is unchanged.

Walkthrough

Codex usage parsing now dates cumulative baselines and adjusts replay and rewind handling. The scan cache advances to version 16 and resets scan positions for older Codex entries. Regression tests cover parsing behavior and cache decoding.

Changes: Codex usage and scan cache

Layer / File(s) Summary
Baseline dating and rewind handling
apps/server/src/provider/Drivers/codexUsage.ts, apps/server/src/provider/Drivers/codexUsage.test.ts
Codex parsing dates cumulative baselines as usage advances. Rewind detection requires a known baseline timestamp. Rejected snapshots restore prior usage and pending requests in specified cases, and unaccounted requests contribute to malformed-record counts. Tests cover replay and rewind scenarios.
Version 16 cache resumability
apps/server/src/usage/usageScanCache.ts, apps/server/src/usage/usageScanCache.test.ts, apps/server/src/usage/UsageService.test.ts
The cache filename and version advance to v16, with v15 recognized as legacy. Codex entries from earlier versions retain cached records but reset their scan position. Tests cover migration, decoding, and the updated filename.

Merge Risk: Minimal · up to be9b8

Codex usage accounting no longer lets a rejected older or replayed snapshot overwrite the cumulative baseline, so replays should not be billed twice. Older cached Codex entries are re-parsed from the start under the new cache version. No actionable merge-blocking risk remains.

Explanation

The title names the main change: a re-emitted Codex snapshot is no longer billed as a counter rewind. The raw summary and objectives confirm that rewind detection now requires a strictly later timestamp, and that re-emitted older snapshots are rejected rather than billed. The title also follows the conventional commit format the template asks for. It does not mention the cache version bump or the null-state crash fix, but those are secondary.

Full details: Description check

Explanation

The description follows the repository template closely. It covers the problem (a rejected same-time snapshot replaced the Codex usage baseline, so the next snapshot was billed twice), the change (commit be9b8f6 treats an older or same-time, lower-counter rejected snapshot as a replay), and scope (a bug fix that supersedes #35536 and references the original author). Verification is detailed: a focused test that failed before the fix and passed after, package test counts, a check run, CI results, and a browser proof with before/after captures. The reproduction on main was not executed, and the description states this. It also lists known limitations. The description has no explicit issue link in the Scope section, but it names the superseded PR and the review finding that motivated the change. The agent attribution is present at the end. Minor gaps: the Scope section does not link an issue, and the description repeats two 'not in this change' bullets. These do not block review.

Major · Data Integrity & Integration · Heavy lift

Keep the cumulative baseline unchanged when an older snapshot is rejected.

rebaseCodexUsage runs before the snapshot is validated. An older replay that is later rejected therefore still replaces lastCumulativeUsage.

For example, take baseline (150, 30) at 10:00:10. A replay at 10:00:05 with cumulative (120, 24) is rejected, because its cumulative delta from the baseline is negative and unreportedRequests returns null. The baseline has already moved to (120, 24). The next snapshot with cumulative (150, 30) and last (30, 6) then passes delta reconciliation and emits 36 tokens that were already counted.

The timestamp guard does not reject this replay. 10:00:05 is not after 10:00:10, so rewound is false, and the snapshot takes the bridge path.

Keep the early rebase for a valid snapshot whose paired request is malformed, as the comment at that line requires. Do not apply it to a snapshot rejected as an older replay. For that replay, leave both lastCumulativeUsage and latestCumulativeAtMs unchanged. Add the replay and the following snapshot to the existing parser table case, and assert that the following snapshot does not emit the already-counted 36 tokens.

A replayed snapshot from before the baseline's time was rejected but
still replaced the baseline, so the replay of the next snapshot
reconciled against it and was billed again. The baseline and the
requests pending against it now stay as they were.

A v15 cache can also hold a baseline whose time is older than its
totals, not only one with no time, and nothing in the state tells the
two apart. The cache moves to v16: a v15 Codex entry is served while its
file is unchanged and re-parses whole once it grows. That replaces the
check for an undated baseline.

… longer becomes the baseline

A rejected snapshot stamped with the same time as the baseline, with
lower counters, still replaced the baseline, so the replay of the next
snapshot reconciled against it and was billed again. It is now treated
as a replay like an older one. A same-time snapshot whose counters
advance or reset to zero is still the next baseline.
