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.
The system shall install the PAM password stack for the lock screen.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
The system shall install the PAM password stack for the lock screen. The system shall install the PAM fingerprint stack only when the target user has an enrolled fingerprint, and shall remove it otherwise. When started as root, the helper shall restrict PATH to trusted system directories and shall invoke fprintd-list only by its packaged absolute path.
when lock_auth_config_run the apply_lock shall always satisfy password_pam_installed & (fingerprint_pam_installed | fingerprint_pam_removed) & !(fingerprint_pam_installed & fingerprint_pam_removed)

Install and upgrade callers start this helper as root. A user-writable PATH entry or a PATH-resolved fprintd-list would run attacker-controlled code with root privileges.

PAM installation matches: password stack installed always; fingerprint stack installed only when fprintd-list (absolute /usr/bin path, PATH restricted under EUID 0) reports an enrolled print, removed otherwise.

Obligations
What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.
The tests that discharge each obligation aren't available for a historical run
The evidence matrix behind each obligation comes from the live audit index, which can't be rebuilt for a past commit. Nothing here means unknown — not that the requirement has no obligations.
Formula evidence
The formal formula behind this requirement, the variables it is written over, and the tests that exercise it (each term is explained inline).

Each row assigns the formula's conditions (T/F) and shows the Result— the formula's value for that input row, not a test pass/fail. A row proves a condition when flipping only that condition flips the outcome. The test that covers each row is linked.
