TestCodexAppServerActivityWindowLogicnever calls the hooks source's activity-window logic.The test writes a file and compares
time.Since(stat.ModTime())to fixed values in the test itself. It never callscodexAppServerHooksActivitySource.scanCandidateor any other production helper, so a regression in the hooks source's mtime-vs-ActivityWindowcheck still passes.The second subtest has the name "old mtime is outside a very short activity window". It only asserts that elapsed time is not negative, so its name does not match what it checks.
CLI-WATCHER.mdpresents these tests as coverage for the codex sources. The test gives false confidence in that coverage.To fix this, move the window comparison into a small pure helper, for example
codexStatusFileRecentlyActive(mtime, now time.Time, window time.Duration) bool. Call that helper fromscanCandidate. Then test the helper with a fixednowon both sides of the window boundary.♻️ Sketch of a deterministic test

Ok, I can confirm this works. Tested with : Connecting to the workspace with Codex and launching a chat will detect activity. It's enough to stop chatting and this will be detected as lacking activity. The activity window can be used to accept a longer period of thread inactivity. Once that is met, the seconds of inactivity prior to idling will control when the workspace gets shut off. 👍 |

Review comments at @timeout/codex_app_server_api_test.go:
- Line 206: Replace the test-name-derived directory from t.TempDir() in the
socket setup with a short path created using os.MkdirTemp, matching the approach
used by the default-socket test so the fake server’s Unix socket path stays
within Linux’s pathname limit.
- Around line 617-619: In the test around `scanCandidate`, avoid inspecting the
child’s environment immediately after `cmd.Start()`: start it with a sentinel
environment variable and wait until that variable appears in
`/proc/<pid>/environ` before scanning. Keep `HOME` and `CODEX_HOME` absent so
the test does not select or connect to an existing server.
Review comments at @timeout/codex_app_server_protocol_compat_test.go:
- Around line 54-55: Update the `cmd.CombinedOutput()` error handling in the
compatibility test to skip only when the Codex CLI explicitly reports that
`generate-json-schema` is unsupported; fail the test for all other command
errors so protocol inspection failures are reported.

…I (CRW-12626)
Extends CLI Watcher with a pluggable ActivitySource architecture and a new
codex-app-server source, so workspaces stay alive while a user is actively
working through Codex Desktop / the Codex VS Code extension / any other
codex app-server client - not just via a TTY-attached shell.
- ActivitySource interface + admin-controlled source selection
(CLI_ACTIVITY_TRACKER_ACTIVITY_SOURCES), with the existing TTY-based
detection unchanged as the tty source (on by default).
- New codex-app-server source (opt-in): connects to a running codex
app-server's own JSON-RPC control socket and polls thread/loaded/list +
thread/read, gating activity on how recently the most-recently-updated
loaded thread's updatedAt timestamp was touched. No managed hooks, no
/etc/codex provisioning, and no root/image-build-time step - only that
the app-server's --listen unix://... socket is reachable, found via
/proc comm+cmdline discovery (codex_app_server_discovery.go). Falls
back to resolving the daemon-assigned default socket path
(${CODEX_HOME:-$HOME/.codex}/app-server-control/app-server-control.sock)
via the target process's own environment when codex was started with a
bare --listen unix:// (no explicit path) - confirmed live this is
exactly how a real production container starts it.
- Gates activity on updatedAt freshness rather than the thread's status
field, after live testing with a real authenticated session showed
status is not a usable signal: polled every 5 seconds across three full
real completed interactions, it reported idle on every single poll,
never once observed as active. updatedAt, by contrast, was cross-checked
against the thread's own turn history and found to track each turn's
real completion time exactly. status/activeFlags are kept only for
verbose diagnostic logging, not for the decision. This also fixes a
second, related gap: a thread sitting on an unanswered prompt no longer
looks indefinitely active just because its status claims so - it ages
out via the same updatedAt/activityWindow comparison once the window
elapses. Does not honor gracePeriod/maxProcessAge.
- The JSON-RPC client sets both read and write deadlines (5s) so a hung
app-server cannot stall the watcher's scan loop; a transport-level
thread/read failure drops the cached connection and stops the scan
(next tick dials fresh), while JSON-RPC error responses (e.g. a thread
that just disappeared) are logged and the scan continues.
- Logs the full scan reasoning at verbose level - loaded-thread IDs, each
thread's status/activeFlags/updatedAt as it's checked, per-thread read
failures, and the freshness decision either way - so an admin can tell
the source is actually reaching the app-server, not just whether it
found something.
- Covers the decision logic with unit tests and integration-style tests
against a fake codex app-server served over a real Unix socket. Adds a
protocol-compatibility test that runs against whatever codex CLI is
actually installed (skipped if none is found) and checks that the
Thread/ThreadStatus schema and the method names this client depends on
still match, so a future codex protocol change fails this test loudly
instead of breaking detection silently at runtime.
Enable with CLI_ACTIVITY_TRACKER_ACTIVITY_SOURCES=tty,codex-app-server
(or just codex-app-server, since tty stays on by default unless
explicitly disabled) on the workspace container. See CLI-WATCHER.md's new
"Activity Sources" section for the full syntax and admin/.noidle split.
