state_monitor.py DOX

Purpose

• Own the state_monitor.py helper module.
• This module tracks dirty state and connection projections for WebUI sync.
• Keep this file-level DOX profile synchronized with state_monitor.py because this directory is intentionally flat.

Ownership

• state_monitor.py owns the runtime implementation.
• state_monitor.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• ConnectionProjection (no explicit base class)
• StateMonitor (no explicit base class)
  • bind_manager(self, manager: 'WsManager', handler_id: str | None=...) -> None
  • register_sid(self, namespace: str, sid: str) -> None
  • unregister_sid(self, namespace: str, sid: str) -> None
  • mark_dirty_all(self, reason: str | None=...) -> None
  • mark_dirty_for_context(self, context_id: str, reason: str | None=...) -> None
  • update_projection(self, namespace: str, sid: str, request: StateRequestV1, seq_base: int) -> None
  • mark_dirty(self, namespace: str, sid: str, reason: str | None=..., wave_id: str | None=...) -> None
• Top-level functions:
• get_state_monitor() -> StateMonitor
• _reset_state_monitor_for_testing() -> None
• Notable constants/configuration names: _STATE_MONITOR_HOLDER, _STATE_MONITOR_LOCK.

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem deletion, WebSocket state, settings/state persistence, scheduler state.
• Imported dependency areas include: __future__, asyncio, dataclasses, helpers, helpers.print_style, helpers.state_snapshot, helpers.ws, helpers.ws_manager, os, threading, time, typing.

Key Concepts

• Important called helpers/classes observed in the source: threading.RLock, field, ws_debug, _ws_debug_enabled, context_id.strip, loop.call_soon_threadsafe, self._schedule_debounce_on_loop, asyncio.get_running_loop, asyncio.current_task, loop.is_closed, self._debounce_handles.pop, self._push_tasks.pop, self._projections.pop, self.mark_dirty, self._mark_dirty_on_loop, runtime.is_development, loop.call_later, StateMonitor, ConnectionProjection, handle.cancel.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_model_config_api_keys.py
  • tests/test_multi_tab_isolation.py
  • tests/test_state_monitor.py
  • tests/test_state_sync_handler.py
  • tests/test_state_sync_welcome_screen.py
  • tests/test_ws_handlers.py
