End a session on its own server once its agent process is gone - #1684
Conversation
The claim records which server the session reports to, so the end is only ever sent there; a session recorded under another profile is left to that server. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 263-269: Filter exited sessions by origin before reaping them:
update the AgentSessions.ReapExited method to accept an optional server and skip
records whose ReadOrigin server does not match it, preserving those records for
the correct drain. Pass Url from the SpoolEnds call, compare normalized server
values case-insensitively via a SameServer helper, and retain the recorded
server when constructing ExitedSession.

Closes #1253 — AI-3392
What & why
When an agent dies without the server hearing about it, its session stays
activein the app for about 30 minutes, until the server's cleanup sweep closes it. This happens to a private daemon agent, or to a daemon that can't reach its server.AgentSessions.Reapalready kept a local exit record when a claimed agent process was gone. That record now also drives aSessionEnd.agent-sessions/<pid>.origin), so the two-line note other readers parse is unchanged.session-end/<vendor>entry withreason: parent_exited. This happens only if it was recorded against the server this process posts to. The drain then delivers it with the usual retries.The issue's open problem, a session recorded under another profile or server, is answered by not posting there at all. That server's own sweep still closes it.
Where to look
A session the server already ended gets this end too, for example one the watcher or daemon closed. The server's session-end handler treats an already-ended session as a no-op.
Verification
AgentSessionsTests(20): a reaped claim returns its recorded vendor and server and drops the sidecar; a dead claim without an origin returns its session alone.SessionEndSpoolTests(3):parent_exitedend on the vendor's route;GitHookTests,PreviousSessionTests,UnusableUrlGuardTestsandLiveWatchHardeningAcceptanceTestspass.🤖 Generated with Claude Code
