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.
Abnormal PAM error increments failedAttempts twice (onError and onCompleted both run handlePasswordFailure)
Low-severity issue, currently open.
Description
The issue as recorded.
Quickshell's PamContext documents error as followed by completed(PamResult.Error). Service.qml wires onError -> handlePasswordFailure (436-437) AND onCompleted's else branch -> handlePasswordFailure (432). The failedAttempts += 1 at 283 has no per-transaction latch, so one abnormal PAM failure counts as two. The failure message then rewrites itself (Authentication failed (n) then (n+1)). Normal wrong passwords take only the completed path and count once.

What protects you, and the fix
What limits your exposure today, and the planned remediation.
What protects you now
cosmetic: counter and message; no auth-bypass
The fix
Handle the failure in onCompleted only (it receives the Error result), or latch the transaction so the error/completed pair increments once
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.
