cache.py DOX

Purpose

• Own the cache.py helper module.
• This module provides in-process cache areas with optional global and area toggles.
• Keep this file-level DOX profile synchronized with cache.py because this directory is intentionally flat.

Ownership

• cache.py owns the runtime implementation.
• cache.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• CacheEntry (no explicit base class)
• Top-level functions:
• toggle_global(enabled: bool) -> None
• toggle_area(area: str, enabled: bool) -> None
• has(area: str, key: Any) -> bool
• add(area: str, key: Any, data: Any) -> None
• get(area: str, key: Any, default: Any=...) -> Any
• remove(area: str, key: Any) -> None
• clear(area: str) -> None
• trim_cache(area: str, seconds: float=...) -> None
• clear_all() -> None
• _is_enabled(area: str) -> bool
• _create_entry(value: Any) -> CacheEntry
• _touch_entry(entry: CacheEntry) -> None
• _get_matching_areas(area: str) -> list[str]
• determine_cache_key(agent, *additional)

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, plugin state, settings/state persistence.
• Imported dependency areas include: dataclasses, fnmatch, threading, time, typing.

Key Concepts

• Important called helpers/classes observed in the source: threading.RLock, dataclass, CacheEntry, time.time, _is_enabled, _touch_entry, _create_entry, _cache.pop, _get_matching_areas, _cache.clear, agent.context.get_data, area_cache.pop, fnmatch.fnmatch.
• 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_browser_agent_regressions.py
  • tests/test_file_tree_visualize.py
  • tests/test_office_canvas_setup.py
  • tests/test_office_document_store.py
  • tests/test_self_update_tag_filter.py
  • tests/test_time_travel.py
  • tests/test_webui_extension_surfaces.py
  • tests/test_whatsapp_bridge_manager.py
