Reverts aa27eb5274 and leaves only the original guard: retire a stable pane's
owner solely when a provider authoritatively answers absent
(probePtyLiveness === false). `true` and `null` still refuse to authorize
destruction, and providers without a probe keep their refusal authoritative, so
their behavior is unchanged.
The follow-up bought too much surface for a P0, and two of its pieces did not
hold up:
- The `hasPty` owner scan added to DaemonPtyRouter.spawn and the degraded
fresh-spawn router is inert for the case it targeted. `hasPty` reads
`activeSessionIds`, which only spawn/attach populate — `listProcesses`
(daemon-pty-adapter.ts) never does. After a failed discovery the scan
therefore cannot find the owner it was written to find.
- Its two routing tests could not fail: the mocks backed `hasPty` and
`listProcesses` with one shared array, giving the fake adapter knowledge the
real DaemonPtyAdapter provably lacks.
Also dropped: the bounded 6s retry loop and its constants, the sentinel symbol,
the exported user-facing message, the `opts.deadlineMs` widening of
probePtyLiveness and its threading through the probe/routers, and the
ensureConnected change in DaemonPtyAdapter.
Kept from the follow-up: the flushOrThrow revert. flushPendingOrThrowAsync is
not a like-for-like twin (drain-to-stable-generation loop, sidecar writes,
per-iteration serialize, rejects when writes are frozen), so
retirePersistedStablePaneOwner stays synchronous.
One gap the strict one-shot gate does open is closed here. `getSize` landed in
daemon protocol v18, and legacy adapters are created for every version in
PREVIOUS_DAEMON_PROTOCOL_VERSIONS (1..30). A pre-v18 daemon error-replies
"Unknown request type", probePtyLiveness catches it as `null`, and one `null`
makes probePtyOwners unprovable forever — so a genuinely dead pane could never
retire. probePtyLiveness now version-gates getSize and asks such a daemon for
`listSessions` instead, the same inventory legacy discovery already routes by,
requested directly rather than through listProcesses (which swallows errors into
an empty list) so an unreachable socket still answers `null`. Unreachable never
means absent; only an owner that answered does.
