The audit found the new machinery could do more harm than the bugs it prevents.
- apply.sh reused the 'nothing left to do' exit -- which touches the PERMANENT
kill switch, cleared only by install.sh, never by update.sh -- for the
incompatible case. On TrueNAS 26 (providers ok, nested opt-out) both modules go
quiet, so the switch would fire and the release that fixed 26 could never
re-enable itself. Retirement and incompatibility now take different exits.
- A network blip, a re-export, or a conditional def all read as BROKEN. Each is
now 'unknown', which changes nothing, rather than evidence strong enough to
disable a module.
- 'native' outranked BROKEN everywhere but apply.sh, so a TrueNAS that reworded
the guard AND reshaped the functions rendered as good news.
- compat.py --tree read B2_BLOCK's own 'restic = True' as native support, so the
documented way to check a live box lied on every patched machine.
- The signature check was a name-subset test. It passed reorders, kw-only
conversions, and added required params -- and it had already passed a real bug:
restic_backup takes 4 args on 24.10/25.04, and the wrapper forwarded 5. Nested
backups have been raising TypeError on those releases the whole time. The
wrapper now forwards *args/**kwargs.
- release.sh --promote was unreachable: it died if the tag existed, the gate died
if it did not. The tests hid it by always tagging first.
The matrix is regenerated daily by CI rather than typed once and forgotten — a
support table that quietly goes stale is a false promise to someone deciding
whether to trust this with their backups.
