- Add GetQuotaRemainingFraction() to Account: returns [0,1] fraction of
remaining quota; 1.0 when no limit is configured (unlimited accounts)
- Add Quota float64 weight field to GatewayOpenAIWSSchedulerScoreWeights
and EnableP2CScheduling bool to GatewayOpenAIWSConfig (both default off)
- Extend selectByLoadBalance scoring with quota factor (gated by Quota>0)
- Add selectByPowerOfTwo(): O(1) P2C selection — samples 2 random candidates,
tries the better-scored one first then the other, falls back to wait plan;
activated when EnableP2CScheduling=true
- Add openAIWSP2CEnabled() helper on OpenAIGatewayService
- Add 6 tests covering quota fraction edge cases, P2C toggle, weight defaults,
single-candidate P2C, two-candidate P2C selection, and quota score ordering
- Add 5th error filter switch IgnoreInsufficientBalanceErrors to suppress
upstream insufficient balance / insufficient_quota errors from ops log
- Extract hardcoded error strings into package-level constants for
shouldSkipOpsErrorLog, normalizeOpsErrorType, classifyOpsPhase, and
classifyOpsIsBusinessLimited
- Define ErrNoAvailableAccounts sentinel error and replace all
errors.New("no available accounts") call sites
- Update tests to use require.ErrorIs with the sentinel error
- Fix bulk edit: send 0 instead of null/NaN to clear load_factor
- Fix edit modal: explicit NaN check instead of implicit falsy
- Fix create modal: use ?? instead of || for load_factor
- Add load_factor upper limit validation (max 10000)
- Add //go:build unit tag and self-contained intPtrHelper in test
- Add design intent comments on WaitPlan.MaxConcurrency
