The 2026-10-10 server service discovery change lists the two historical
unit names with one pattern read and refuses to continue when that read
exits non-zero. systemctl list-unit-files exits 1, printing nothing on
stdout or stderr, when none of the named unit files exist. That is every
fresh host, so install.sh refused with "Cannot identify the Pulse systemd
service: unit inventory failed" before it did any work. The first beta's
install.sh smoke test caught it on a clean Debian 12 container; no
release carries it, and v6.5.0 listed the whole inventory and grepped it.
The tests could not see it. Their systemctl double reports "no units" as
exit 0, and test_partial_failed_inventory_is_not_absence asserted that an
empty inventory with exit 1 must be refused, which is the defect itself.
Add one inventory read shared by the installer and the unattended
updater, and use it for the auto-update mask check, which had the same
hazard. It accepts exactly the silent exit 1 as an empty inventory, and
only after a second read confirms there is still no output and no
message. A timeout, a signal, any other status, or an exit 1 that carries
output or a message stays a failed inventory, so a real failure still
cannot pass as absence.
Make the doubles model systemd: a failure now prints its message, silent
exit 1 is absence, and a new test runs real systemctl --root over an
empty unit root for both scripts. Run against the unfixed scripts, the
four new fresh-host tests fail; the rest of the suite is unchanged.
The registered runtime proofs for install.sh and the unattended updater,
which drive this suite, now require the fresh-host controls to have run
and passed, so they cannot be skipped or deleted unnoticed.
Refs: #2785
The complete installer package correctly stopped its old re-entry fixture at unavailable mask evidence. Admit exact unmasked fixture units and record the sole daemon-reload operation instead of depending on a real host manager. Exercise the actual CLI re-entry with both effective runtime masks as well; retain refusal and all assets unchanged.
Contract-Neutral: Confined test admission and CLI coverage only; no installer runtime or subsystem contract change.

Reconcile the returned timer-discovery repair: both exact units must have a successful bounded unmasked inventory before shared asset staging. Keep configured, runtime and off-destination persistent masks and all assets unchanged across every installer consumer, explicit setup and sandbox repair. Unknown or failed inventory stops replacement; enabled and disabled refresh remains consent-preserving.
Change-source: pulse-maintainer
Match complete systemctl inventory rows by exact unit field with bounded reads, so updates and reinstalls reach the existing helper refresh. Preserve deliberate timer and updater masks instead of replacing their symlinks. Exercise all five installer consumers, unchanged settings and enablement, failure/timeout controls and actual fixture-root systemctl inventory.
