 Key invariants:
 - Every direct-provider `AgentRuntime::start_turn` performs exactly one model call; only `ProviderRun` may schedule another turn or retry
-- Direct-provider model calls allow 120 seconds for stream startup and 300 seconds between stream events; either timeout is a recoverable transport failure that enters the existing bounded retry lifecycle with the same work identity
+- Direct-provider model calls allow 120 seconds for stream startup and 90 seconds between stream events; either timeout is a recoverable transport failure that enters the existing bounded retry lifecycle with the same work identity
 - Direct-provider remote telemetry records requested, started, retry-scheduled, and finished model-turn phases with explicit `llm_finished` state; root `provider_run_finished` records distinguish clean completion from failure or cancellation and mark the response stream terminal
 - `use_rig` and provider selection may choose request/transport details but must never choose lifecycle ownership
 - Direct-provider output may be projected through `ResponseStream`, but provider progress must not depend on response-stream result draining or `AfterStreamFinished`
