- mark Codex bearer/refresh failures as terminal auth-expired states
- sync refreshed session auth back to rotation slots and revive refreshed dead_auth slots
- stop paired arbiter retry loops when Codex accounts are unavailable
- add regression coverage for rotation leases, follow-up suppression, and arbiter closure
- Remove OPENAI_API_KEY from .env and Codex child process env to prevent
API billing when subscription quota is exhausted
- Remove writeCodexApiKeyAuth entirely — Codex now uses OAuth only
- Add 9-pattern secret redaction in formatOutbound() to prevent key leaks
- Fix Codex usage bucket aggregation: use 'codex' bucket only instead of
max across all buckets (bengalfox = Codex Spark, not needed)
- Add d7≥100% auto-rotation in updateCodexAccountUsage to skip exhausted
accounts and prevent API billing fallback
- Add findNextCodexAvailable that checks both rate-limits and d7 usage
- Clean stale apikey auth.json files from all session directories
- Update tests: OAuth-only auth, d7 auto-skip (3 new tests), dashboard
