Omarchy
ProbeLabsviewing a historical runA proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.
fingerprintPam.start() returning false disables fingerprint auth for the rest of the lock with no retry
Low-severity issue, currently open.
Description
The issue as recorded.
startFingerprint (shell/plugins/lock/Service.qml:294-295) clears fingerprintAuthenticating when fingerprintPam.start() returns false but arms no timer. Only handleFingerprintFinished and the PAM onError path restart fingerprintRetryTimer; neither runs when a conversation never began. The per-event callers (onSecureStateChanged, fingerprintCheckProc.onExited) fire once - so a transient start failure leaves fingerprint dead until some unrelated event re-runs startFingerprint.

The fix
Arm fingerprintRetryTimer in the start()-false arm so the offer comes back on the same lock
Blast radius
If you touch this issue, what else may need re-checking — the requirements it affects and the code and tests that hang off them. Historical view: authored trace links only — automatically derived links aren't reconstructible for past runs.
No authoredcode links reach these requirements in this historical reconstruction. Automatically derived code links aren't reconstructible for past runs, so implementing code may have existed without an authored trace.
