* fix(native-chat): start Windows chats without reading process creation times
Native chat on Windows refused to start ("Orca can't run this agent in a chat
here") whenever the process-table addon could not report process creation
times. Chat never needed them; only the bookkeeping around stopping the agent
did.
Windows now follows the common pattern: Stop ends the agent's tree with
`taskkill /T /F` on the child Orca still holds, and reports the tree gone only
when taskkill exits 0. A saved pid is never signalled after a restart.
- Remove the Claude and Codex location gate and the Codex launch refusal.
- A start time that cannot be read is recorded as unknown instead of refusing
the session; recovery already releases such an owner without signalling it.
- Delete Claude's Windows creation-time descendant snapshot and its verifier.
- Codex's Windows teardown reports the real taskkill outcome.
- The renderer no longer waits on the capability flag; the host keeps
publishing it for older clients (temporary).
* fix(native-chat): treat a Windows Claude exit after stdin end as a proven close
On Windows an idle Claude leaves on its own once its stdin ends, so every Stop
and close read as unproven: live background work settled as unknown and the
trace logged a close that "did not finish cleanly". As with the Codex close,
that exit is now the close and Orca makes no claim about processes Claude
started; a forced close still rests on taskkill's own report.
Also drop the Settings clause about Windows needing process start times, and
fix comments and the tracked process-enumeration doc that still described the
removed start-time gate and descendant snapshot.
* fix(native-chat): renew a held child's lease without a PID probe
An owner recorded without a process start time could never renew: the renewer
re-proves every live owner by PID identity, and with no start time and no
spawn-token echo that probe is indeterminate. The lease's last renewal then
stayed at the spawn, so a turn cut by an Orca crash was dated to its own start,
and every tick logged a failed renewal and split the batch into one store
transaction per chat.
The runtime now renews a lease for a child it still holds at the record's
fence and whose exit it has not received, recorded as a `held-child` match.
Receipt of the exit ends that proof before the exit is settled, and a restart
holds no child, so a dead owner's lease still expires and restart adjudication
is unchanged. Records this runtime does not hold keep the PID probe.
Also correct the identity probe's comment about shipped addons and note that
recovery's stop ladder is POSIX-only.
* fix(native-chat): keep a failed Windows taskkill unproven across a retried close
A Windows close counts Claude leaving on its own after its stdin ends as the
close. That shortcut also caught a retried close whose first attempt forced a
taskkill that failed: once the root exited, the retry returned true and the
failure read as a proven close. The tree reaper now records whether a reap
ever reached the live root, here, on an earlier close or from a transport
failure, and the shortcut applies only when none did; otherwise taskkill's
verdict stands and no new taskkill runs against the exited root.
Pin the platform on the existing tests that assume the POSIX close, and say
what `exit-proven` means on Windows in the acquisition-failure docs.
* fix(native-chat): derive a held child's liveness from the adapter's own handle
Lease renewal trusted a held child until the host settled its exit, and the
host hears of an exit late: Claude runs its close ladder and a store write
first, unexpected exits wait on one delivery chain shared by every chat, and a
Claude close that cannot prove its tree publishes nothing at all. A dead root
could keep renewing through that window, so a crash in it dated the cut turn
late. Renewal now asks the adapter, which owns the process handle and sees the
exit first: a child is held only while it is on record at the lease's fence
and its adapter still runs that exact acquisition with no root exit seen. An
adapter that cannot answer falls back to the PID probe. The stored
exit-received mark is gone.
The held-child read is now required by the runtime state and the renewer, and
a host-level test drives renewal through the real host wiring.
