`src/managers.rs` — `LoopManagers`, the component bundle

One struct holding every optional engine component; built by you, consumed by the engine, accessed through the capability traits.

Key items

  • Always present: FallbackManager, DetectionManager, ObserverHost. Optional (Option): context manager, stream handler [streaming], hook executor [hooks], pipeline, health registry [tool_health], memory.
  • Builders with_observer (appends!), with_fallback, with_detection, with_pipeline, with_context_manager, with_memory, with_stream_handler, with_hook_executor, with_health_registry.
  • Setters: the set_* mirrors + register_observer.
  • reset_all() — fallback + detection + observer reset; memory and the rest keep their state; never called automatically.
  • notify_detected_pattern(pattern, turn) — observer fan-out for detection events (deciding stays with the engine).

Behavior notes

  • BareLoop::new_with_managers seeds a default ContextManager (truncating compactor, synced from SessionConfig) when the bundle has none; your own is never overridden.
  • Not Clone — moved into the engine; share the Arc-wrapped parts before building.
  • The default fallback manager has an empty chain — trips without changing the routed model until you configure backups.
