The remediation grew beyond the original no-autobind fix, leaving
public docs and nearby comments describing connect-only discovery,
XDG-only socket paths, raw readiness probes, and old cleanup naming.
Document typed registrar probing, occupied-address rejection, Darwin's
short runtime directory, platform-aware socket cleanup, sentinel
readiness, and subprocess output draining. Add the GH #473 bugfix
fragment and update regression rationale without changing task states.

The discovery `daemon` fixture probed UDS readiness by connecting and
immediately closing. That entered Tractor's actor handshake without an
`Aid` payload and destabilized the remote registrar on macOS before
test roots attempted discovery.
Run the child through a small `open_root_actor()` wrapper and publish a
filesystem sentinel only after runtime startup completes. Poll that
sentinel with process-liveness checks and guaranteed setup-failure
cleanup, without touching the transport socket.
Cover transport-free readiness and deterministic polling backoff.
Caught-during: review remediation
Found-via: `/run-tests` discovery daemon fixture consumers
Cause: initial sentinel drafts mishandled `pytest.Testdir`, emitted
invalid `python -c` syntax, and misplaced return-code logging.
