- Cache layer: LRU cache + TTL untuk non-streaming LLM responses (CACHE_TTL, env: CACHE_TTL, CACHE_MAX_SIZE) - Retries: turunkan default dari pool.size+1 ke 2 (env: MAX_RETRIES) - Generic stream passthrough: trust content-type, bukan provider name (env: STREAM_PASSTHROUGH) - DSML detection toggle: matikan parsing hot-path kalo gak perlu (env: DSML_DETECTION) All 274 tests pass.
