Module cache 

Per-session tree snapshots.

Unix files are created mode 0600. XDG_CACHE_HOME wins on every OS so tests can point at a temp directory. Without it, Windows uses %LOCALAPPDATA%\computer-use\cache and other platforms use ~/.cache. dirs::cache_dir is not used: on macOS that is ~/Library/Caches, and the session path contract is ~/.cache.

Structs

PruneOptions

Options for prune_sessions.

PruneReport

Directories prune_sessions removed or left in place.

Snapshot

One saved observation. Secure-field values are already redacted in root.

Constants

DEFAULT_SESSION_TTL

Sessions older than this, whose owner process is not alive, are stale.

Functions

cache_dir

Cache root: foreground.lock and overlay.sock live here, next to sessions/.

clear_restores

Drop Electron edits after a successful restore so a second teardown is a no-op.

load

Read the snapshot for one app window, if a previous call stored one.

load_screenshot_map

Read the last screenshot map for this session, if one was stored.

pending_restores

Electron edits recorded for this session, one per pid.

pid_alive

True when pid is still running. Signal 0 does not deliver a signal.

prune_empty_sessions

Drop empty session directories under the real cache. Content is left alone.

prune_sessions

Remove empty session directories and stale ones under root.

session_dir

Directory for one session. Creates it, mode 0700, and writes owner.json once.

sessions_root

Directory that holds every session. This does not create it.

store

Write a snapshot. An older Electron edit is kept when the new one has none.

store_screenshot_map

Write the last screenshot map. This file is not a tree snapshot.

write_secret_bytes

Write bytes with mode 0600 on Unix.
