The Unraid install path killed the running agent but never the wrapper
supervising it, then appended a second wrapper at the end of the install. The
survivor and the newcomer both loop trying to own the same agent id, and
because the old wrapper is a watchdog it respawns the agent mid-install with
the previous binary and arguments. Observed on a live Unraid host: a
supervisor from a July install was still running beside the one the reinstall
had just started.
Nothing reports this as a failure. It presents later as an agent that
restarts on its own or reverts to superseded arguments.
Stop the wrapper first, then the agent: killing a supervised agent while its
wrapper still loops only races the respawn. The pattern matches the trailing
path segment so a wrapper left at an older storage location is caught too,
with the dot escaped and the far end bounded so a co-installed agent's
supervisor (start-pulse-agent-prod.sh) is not.
The QNAP branch already stopped its wrapper, which is what made the Unraid
omission visible; the contracts now require every wrapper-writing branch to
own the same teardown.
Guarded by two tests: one pins that the Unraid branch stops the wrapper and
does so before the agent, the other pins that the wrapper pattern spares a
sibling supervisor, with a premise check that the loose pattern really does
match so neither assertion can pass vacuously.
