fix(quota): ignore Command Code epoch-zero reset timestamps

[yansigit]

Summary

• Command Code's unused 5-hour window sends resetAt: 0 as a sentinel, not a clock.
• OpenCodex treated that 0 as Unix seconds, so the provider overview showed Resets 31 Dec 1969, 17:00 while the weekly window still formatted correctly.
• normalizeResetAt() now drops non-positive timestamps, so the 5-hour bar still reports 0% used but no longer invents an epoch reset date.
• Signed numeric sentinels such as "-1" now go through epochMillis instead of Date.parse, which otherwise produces a historical date.

Verification

• Watched bun test tests/command-code-quota.test.ts -t "omits a zero Command Code window reset" fail first with fiveHourResetAt: 0.
• Watched bun test tests/command-code-quota.test.ts -t "omits a signed numeric Command Code window reset" fail first with fiveHourResetAt: 978307200000 from Date.parse("-1").
• After the follow-up: bun test tests/command-code-quota.test.ts tests/provider-quota.test.ts tests/opencode-go-quota.test.ts — 112 pass, 0 fail.
• bun run typecheck — clean.
• bun run privacy:scan — passed.

📝 Walkthrough

Walkthrough

The quota provider now rejects non-positive reset timestamps and centralizes seconds-to-milliseconds conversion through epochMillis. Regression tests cover zero and signed numeric resets while preserving valid weekly reset data.

Changes

Quota reset normalization

Layer / File(s)	Summary
Normalize and validate reset timestamps src/providers/quota.ts, tests/command-code-quota.test.ts	normalizeResetAt validates numeric strings and parsed dates, rejects non-positive timestamps, and uses epochMillis for unit conversion. Tests verify that zero and signed reset values are omitted while valid weekly reset data remains reported.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 1c838

This localized change stops epoch-zero and signed numeric sentinel values from rendering historical reset dates while preserving normal quota formatting. It is mergeable with explicit owner awareness that the provider test fixture still accepts unexpected requests, which could let some request-shape regressions pass unnoticed.

The epoch-zero bug is real and this is the right scope, but two correctness boundaries remain before merge:\n\n1. In , the numeric-string regex accepts only unsigned values. A sentinel such as therefore falls through to and can become a valid historical date instead of being rejected by . Accept an optional sign for numeric strings and let reject zero/negative values. Please add a focused signed-string regression.\n2. The new fetch mock returns the rolling-window payload for every URL that is not one of the three auxiliary endpoints. That can hide a future or accidental extra request. Match the exact rolling-window endpoint and throw or return an error for every unexpected URL.\n\nAfter those are fixed, re-run the focused quota tests, typecheck, privacy scan, and exact-head CI.

The epoch-zero bug is real and this is the right scope, but two correctness boundaries remain before merge:

1. In normalizeResetAt, the numeric-string regex accepts only unsigned values. A sentinel such as "-1" therefore falls through to Date.parse and can become a valid historical date instead of being rejected by epochMillis. Accept an optional sign for numeric strings and let epochMillis reject zero/negative values. Please add a focused signed-string regression.
2. The new fetch mock returns the rolling-window payload for every URL that is not one of the three auxiliary endpoints. That can hide a future or accidental extra request. Match the exact rolling-window endpoint and throw or return an error for every unexpected URL.

After those are fixed, re-run the focused quota tests, typecheck, privacy scan, and exact-head CI.

[yansigit]

Addressed the requested-changes review on 1c838d28f:

1. Signed numeric reset strings such as "-1" now go through epochMillis instead of Date.parse.
2. The new Command Code quota mocks accept only /alpha/billing/credits and throw on unexpected URLs.

Focused quota tests, bun run typecheck, and bun run privacy:scan are green on this head.

[Ingwannu]

The two requested correctness fixes are present on exact head 1c838d28f:

• signed numeric reset strings now enter epochMillis, so zero/negative sentinels cannot fall through to Date.parse;
• the quota mock accepts only the exact credits endpoint and rejects unexpected requests.

I reran the focused Command Code quota suite (13/13), typecheck, privacy scan, and diff check on this head. The Linux shards and other completed CI jobs are green; merge should wait for the remaining macOS job to finish successfully.

This is TypeScript provider-quota control-plane logic; there is no separate Go-native counterpart to port.

[Ingwannu]

The remaining macOS job failed after its only executed test printed OS keyring create/read/delete smoke passed. The step then sat until 00:23:32 with no test failure output; Linux shards, npm-global macOS, and the dedicated macOS keyring job are green. This does not intersect the two-file quota diff and is consistent with runner/orphan cleanup instability rather than a quota regression.

I am rerunning the failed job. Merge remains blocked until the rerun is green.
