create_task.py:
- Remove dead make_client() call before the verify branch; it was called
unconditionally with host=None/key=None, creating a broken client that was
immediately discarded or overwritten.
- Remove "verify" from the dispatch dict; it was never reached through dispatch
(the if/cmd==verify branch above it handled it). Dispatch now only contains
commands that actually use a client.
- Wrap json.load() in try/except (OSError, JSONDecodeError) so a corrupt or
partially-written status file produces a useful message instead of a traceback.
sitecustomize.py:
- Call _record_status() on the early-return paths in both _patch_b2 and
_patch_restic. Without this, if TrueNAS natively supports B2 or the patch
is already applied, the status file was never written and `verify` always
reported failure even when everything was fine.
- Add idempotency guard to _record_status(): first call wins; duplicate calls
for the same module are ignored so the entry count stays accurate.
- Make B2 get_restic_config a @staticmethod. The method never used self; the
noqa comment was suppressing the evidence of a design mismatch. Removing the
unused parameter makes the intent explicit.
- Add NamedTuple._replace() fallback after dataclasses.replace() in the restic
wrapper. If ResticConfig is ever refactored to a NamedTuple, the TypeError
from dataclasses.replace() would have surfaced as a backup job failure rather
than a graceful recovery.
