📝 WalkthroughWalkthroughShort-window quota data is now recognized, persisted, included in Codex usage scoring, and used for routing headroom, exhaustion, and reset calculations. Tests cover K12, free plans, quota caching, and pool evidence. ChangesShort-window quota support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Cached quota routing can make incorrect availability decisions when short-window data is refreshed: stale long-window fields may be retained inconsistently, and reset times from parsed responses may be missed because of timestamp-unit differences. These bounded correctness issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

WHAM's reset_at values are Unix seconds, and parseUsageQuota stores that value unchanged in shortResetAt (for example, 2000000000). Adding it directly to this list compares it against millisecond-valued Date.now(), so every real burst reset is filtered out and cached route evidence omits resetAtMs; the new test masks this by constructing shortResetAt with Date.now(). Normalize second-valued Codex reset timestamps to milliseconds before filtering and emitting them.

When a WHAM refresh has cached shortPercent, any later response containing ordinary quota headers calls applyAccountQuotaFromUpstreamHeaders, but parseUpstreamQuotaHeaders never emits any short* fields. This block therefore skips the existing burst fields while rebuilding the cache entry, making routing and the dashboard lose the independently enforced burst limit until the next WHAM refresh. Preserve the existing burst fields for partial/header snapshots, or classify sub-day header windows into the short slot before replacing the entry.

Handle short-only snapshots consistently in setAccountQuotaFromParsed.
parseUsageQuota can return only the short-window fields when the primary window is sub-day and the other windows are absent. The merge then retains stale weekly fields but drops stale monthly fields. Choose one policy for short-only snapshots: preserve both long-window fields for partial updates, or clear both for authoritative snapshots. Add a regression test for this case.

Cover burst-field retention on a credits-only refresh.
The new copy path is not covered by the existing credits-only test in tests/rate-limit-reset-credits.test.ts, Lines 394-406. That test checks only weekly and monthly fields. Seed shortPercent, shortResetAt, and shortWindowSeconds before applying a credits-only response, then assert that all three fields remain.
As per path instructions, “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

Normalize Codex reset timestamps before routing
normalizeResetAt only validates values and preserves Unix-second reset_at values (src/codex/quota.ts:178-185). The filter in src/routing/quota.ts:50-55 compares weeklyResetAt, monthlyResetAt, and shortResetAt with millisecond Date.now(). Parsed reset values such as 2000000000 therefore fail the filter, and resetAtMs is omitted. The routing test uses Date.now() + 60_000 directly and does not cover the parsed path.
Store Codex reset timestamps in milliseconds at the parser/cache boundary, or use seconds consistently across the routing contract. Add a parsed-input routing test.
