Follow-up to #22558 / #22376
#22558 fixed #22376 on main: a snapshot whose cumulative counters equal its own request now starts a new counter sequence. One case is still wrong on main. If Codex re-emits the first snapshot of the current sequence, that replay also has cumulative equal to its request, so it is treated as another restart. The request is billed a second time, the baseline moves back, and the next real request fails the delta check. It is dropped and counted as a skipped record.
On main, the sequence request 100+20 (cumulative 100+20), then cumulative 200+40, then a replay of the first snapshot, then cumulative 300+60 bills [120, 120, 120, 0] with 1 skipped record. The expected result is [120, 120, 0, 120] with 0 skipped.
apps/server/src/provider/Drivers/codexUsage.ts: when a snapshot starts a sequence, the scan state remembers it in a new optional sequenceStartUsage field. A later restart-shaped snapshot that is identical to it is dropped as a replay. The baseline stays where it was and nothing is counted as skipped. Everything else is #22558's logic, unchanged.
The field is optional, so scan states cached before it existed still decode. A cache written before this change has no recorded sequence start, so the replay guard only applies from that file's next restart or re-parse. I didn't bump the cache version, because that would force a full re-scan of every Codex history for a rare case.
Limit: a genuine restart whose first snapshot is identical to the current sequence's first snapshot would also be dropped as a replay.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This is a narrowly scoped server usage-parser fix with regression coverage, but it changes which Codex requests become UsageRecords and therefore affects token and cost aggregation. Human review is warranted for this metering-sensitive runtime behavior.

Do not treat an older re-emitted snapshot as a counter restart.
After snapshots (100, 20) and (200, 40), a re-emission of the first request with last=(100, 20) meets restarted. The parser emits that request again and replaces the baseline with (100, 20). The equal-snapshot check does not stop it because the current baseline is (200, 40). Require evidence that the event starts a new sequence, or reject an already-seen event before accepting the reset. Add a replay case to the tests.

Fixed in ee93d23772: a restart candidate that matches the snapshot that started the current counter sequence is now ignored as a stale replay, so it isn't counted again and the baseline doesn't move back. Covered by ignores a replay of the current sequence's first request without moving the baseline back.
@fixfon Thanks for fixing this. The guard ignores the replay and preserves the cumulative baseline. This addresses the reported case.

Clear sequenceStartUsage when a compaction marker resets the counter.
The zero-component branch can set lastCumulativeUsage to zero but leaves sequenceStartUsage unchanged. If the first request after the reset has the same usage fields as that stale sequence start, the replay guard drops it and restores the zero baseline. Later cumulative deltas can then be rejected as malformed.
Clear sequenceStartUsage only when the marker's cumulative snapshot is all zero. Preserve it for markers that do not reset the counter.

Clear sequenceStartUsage when fork-copy suppression consumes a zero cumulative marker.
A restarted cumulative record can set sequenceStartUsage before the first accepted fork session_meta. While fork-copy suppression is active, a zero cumulative record updates lastCumulativeUsage and returns before the normal zero-marker branch clears that baseline. The next genuine request matching the remembered start is then treated as a replay and skipped. Its following delta can also fail validation against the restored baseline.

Use total_tokens to identify a zero baseline.
The parser accepts context estimates with zero input_tokens and output_tokens but a positive total_tokens. rebaseCodexUsage clears sequenceStartUsage before it validates the paired record. A later replay of the original first request can therefore be billed again.

Thanks, I checked this with a test. An estimate followed by a replay of the sequence's first request is byte-identical to an estimate followed by a genuine restart with the same counters, so switching to total_tokens === 0 would only move the miss to the other case. The clear deliberately follows the input+output rule the parser already uses for zero-component records. On main every such replay is billed twice anyway, so I'm leaving this as is.
@fixfon Thanks for the clarification. The snapshots cannot distinguish a replay from a genuine restart with identical counters. Switching to total_tokens === 0 would change which case is misclassified, not remove the ambiguity.
The current condition also matches the parser’s zero-component rule. I withdraw the suggested change.

| 5 | Learning: In apps/server/src/provider/Drivers/codexUsage.ts, zero-component Codex records use input_tokens + output_tokens === 0, even when total_tokens is positive. rebaseCodexUsage deliberately uses the same rule to clear sequenceStartUsage. After such a record, a replay of the sequence's first request and a genuine restart with identical counters are indistinguishable from the usage snapshots alone. Changing the clear condition to total_tokens === 0 does not resolve that ambiguity. |

thanks @fixfon. your first-snapshot guard, baseline preservation, and zero-reset regressions address the replay bug. i kept your commits and tests, merged current main, and pushed d3117a39d869f5ef5f70dd2cdcca48becf71b665 to this branch.
changed the remembered sequence start to a timestamp-and-counter signature. equal counters at a later timestamp now count as a genuine reset, while an exact replay leaves the current baseline intact. the production diff is four lines shorter than the original; only the existing parser and test files change.
verification:
[120,120,120,0], one skipped record. the original replay regression passes on this head: [120,120,0,120], none skipped.[120,120,0,0], one skipped record. this head yields [120,120,120,35], none skipped.vp run check:changed passes format, lint, both knip checks, generated graphql, affected server/scripts typechecks, and all 33 parser tests.rollout limits: existing cached historical totals are retained; this does not repair past overcounts. older cached state learns the replay signature at its next sequence start or a cold reparse. @fixfon, the rollout format has no unique request id here, so a replay rewritten with a new timestamp remains indistinguishable from a genuine reset. no live Codex-produced replay, upstream billing, installed desktop/mobile clients, macos/windows, or remote/relay/tunnel verification is claimed. all clients consume these shared server totals; no UI or wire contracts changed.

linux chrome, driven with the repo playwright and /usr/bin/google-chrome, against one background dev server at a time. main: 9ebca5f71c in ../main; pr: exact head d3117a39d869f5ef5f70dd2cdcca48becf71b665. ran vp i in both checkouts. created the project and threads through the app, then used real codex gpt-6.1-sol through the local proxy (codex 0.164.0). no mock provider, synthetic rollout, fixtures, or transcript edits.
main completed two turns, a fork continuation, a server restart/resume, and edit-from-here followed by another turn. the pr cold-scanned that unchanged history: both showed 100,841 processed tokens (101k in the ui). on the pr, two fresh turns, fork continuation, warm-cache restart, and a resumed turn worked. native provider records and the web client's actual server.getUsageSummary response agree:
| 1 | main real requests: 5, tokens: 100841 |
| 2 | pr cold scan of identical history: tokens 100841 |
| 3 | pr after two new turns: records 7, sessions 3, tokens 138727 |
| 4 | pr after fork continuation: records 8, sessions 4, tokens 158928 |
| 5 | pr after warm-cache restart: records 8, sessions 4, tokens 158928 |
| 6 | pr after resumed turn: records 9, sessions 4, tokens 179161 |
| 7 | final codex source: ok, scannedFiles 5, skippedFiles 0, malformedRecords 0 |
| 8 | independent sum of 9 unique native response usage records: 179161 |
| 9 | exact repeated token snapshots observed: 0 |
blacksmith ran the existing focused suites: 33 codex parser tests and 9 scan-cache tests passed. the head has 28 successful ci checks, none failing or pending. no source changes or pushes were needed.
main, real provider history:
pr, identical history:
real fork continuation and refresh; this shows neighboring behavior, not the rare replay:
final resumed-turn total:
the replay-specific fix remains unverified. these real sessions never emitted the required first-snapshot replay with its original timestamp after a later snapshot. i could not reproduce the original bug on main or exercise the new replay guard in the running pr. resume, fork, and edit actions do not let the client request that old event. matching screenshots prove unchanged ordinary accounting, not replay suppression. passing synthetic regression tests do not replace that missing live proof.
also unverified: zero-counter compaction resets, equal-counter genuine resets, historical cache repair, installed desktop/mobile clients, macos/windows, remote/relay/tunnel modes, and upstream billing. the local proxy usage-limit endpoint returned JSON-RPC -32600 on main, so limits are unverified. the pr initially hit a vite dynamic-import startup failure; reloading recovered and subsequent flows worked. no provider or app turn stalled for ten minutes.
result: partial runtime verification. the requested replay-specific proof is unavailable. code is unchanged; recording the target behavior as unverifiable rather than claiming it works as-is.
