Summary

The Docker container runs uvicorn synthorg.api.app:create_app --factory which calls create_app() with no arguments. Only persistence is auto-wired from SYNTHORG_DB_PATH. All other services are None, causing 503 errors on most endpoints.

Current State

server.py documents this: "Backend services not passed -- intended for development/demo use. For production, call create_app() directly with all services."

The app logs this at startup:

[warning] create_app called without persistence, message_bus, cost_tracker,
task_engine, and/or settings_service -- controllers accessing missing services
will return 503.

Services Audit

All implementations exist and can be auto-created from config + persistence:

Affected Dashboard Pages

Without these services, the dashboard shows errors on:

Proposed Approach

Add auto-wiring in create_app() following the existing persistence pattern:

# After persistence is wired:
if message_bus is None:
    message_bus = InMemoryMessageBus(config=effective_config.communication.message_bus)

if cost_tracker is None:
    cost_tracker = CostTracker(budget_config=effective_config.budget)

if task_engine is None and persistence is not None:
    task_engine = TaskEngine(persistence=persistence, message_bus=message_bus)

# After _init_persistence in on_startup:
if settings_service is None and persistence is not None:
    settings_service = SettingsService(
        repository=SettingsRepository(persistence),
        registry=build_settings_registry(),
        config=effective_config,
    )

Services with more complex dependencies (coordinator, meeting_orchestrator, etc.) can be wired incrementally.

Dependency Order

persistence (already done)
  -> message_bus (no deps beyond config)
  -> cost_tracker (no deps beyond config)
  -> settings_service (needs persistence + registry)
    -> settings_dispatcher (needs message_bus + subscribers)
    -> config_resolver (needs settings_service)
  -> task_engine (needs persistence, optional message_bus)
  -> provider_registry (needs config)
  -> agent_registry (needs persistence)
  -> coordinator (needs provider_registry + task_engine)
  -> meeting_orchestrator (needs message_bus + provider)
  -> meeting_scheduler (needs orchestrator + config)
  -> performance_tracker (needs persistence)

Acceptance Criteria

• create_app() with no arguments auto-creates all services that have existing implementations
• Dashboard loads without 503 errors (budget, tasks, analytics, company, settings pages)
• Services are created in correct dependency order
• Startup warning removed (or changed to only warn about genuinely missing services)
• Tests verify auto-wiring works
