Follow-up to the holistic review of the PIN-unification branch:
- /system/status now reads the real arm state from the arm_state_log
table via get_current_arm_state, instead of returning a hardcoded
'DISARMED' stub. Without this, polling after the new async 202
arm/disarm flow was a UX dead-end — clients never saw the state
change they just requested. DB read failures degrade gracefully.
- Operator guide: correct the claim that 'vigilar config set-pin'
populates recovery_passphrase_hash. It doesn't. recovery_passphrase
_hash has no CLI helper today; it must be set manually.
- Tests: add a fail-closed regression for verify_pin on malformed
stored hashes, and a companion test confirming the deprecation
warning stays silent on a fully migrated config.
All address specific review comments on the branch; no scope creep.

Describes the canonical [security] pin_hash key, the PBKDF2 format
emitted by 'vigilar config set-pin', and the deprecation warning for
the legacy [system] arm_pin_hash. Drops the three-way mismatch
known-limitation.
