Integrated into release/v3.6.5. Added CHANGELOG breaking change entry for the removed /api/settings/codex-service-tier endpoint and deduplicated getCodexRequestDefaults in page.tsx (now imports from requestDefaults.ts).
Keep the original combo and budget exhaustion errors when global or
emergency fallbacks also fail so callers see the real upstream cause.
Also preserve translated responses for memory extraction before output
post-processing, track pending rate-limit async work for deterministic
test resets, and expose usage helpers needed for deeper branch
coverage.
Expand unit coverage across moderation, media generation, streaming,
response logging, usage helpers, and fallback proxy error handling.
Move chat pipeline validation, circuit breaker execution, proxy
resolution, logging, and session header handling into dedicated
helpers to keep the SSE handler smaller and easier to verify.
Also fix shared API option precedence, rebuild skill version caches
after deletions, ignore api.trycloudflare.com false positives, and
add rate-limit manager test flush/reset hooks for deterministic
coverage.
Expand integration and unit coverage across chat routing, auth,
cloud sync, skills, executors, streaming, DB helpers, proxy handling,
and provider/model utilities.
