 - Agents/OpenAI Responses: add `models.providers.*.models.*.compat.supportsPromptCacheKey` so OpenAI-compatible proxies that forward `prompt_cache_key` can keep prompt caching enabled while incompatible endpoints can still force stripping. (#67427) Thanks @damselem.
 - Agents/context engines: keep loop-hook and final `afterTurn` prompt-cache touch metadata aligned with the current assistant turn so cache-aware context engines retain accurate cache TTL state during tool loops. (#67767) thanks @jalehman.
 - Memory/dreaming: strip AI-facing inbound metadata envelopes from session-corpus user turns before normalization so REM topic extraction sees the user's actual message text, including array-shaped split envelopes. (#66548) Thanks @zqchris.
+- Agents/errors: detect standalone Cloudflare/CDN HTML challenge pages before transport DNS classification so provider block pages no longer appear as local DNS lookup failures. (#67704) Thanks @chris-yyau.
