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.
omarchy-apply-lock shall test fingerprint enrollment by invoking /usr/bin/fprintd-list for the target user.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
omarchy-apply-lock shall test fingerprint enrollment by invoking /usr/bin/fprintd-list for the target user. The helper shall not resolve fprintd-list through PATH.
when fingerprint_enrollment_queried the apply_lock shall always satisfy fprintd_absolute_path_only

Hazard review
- scenarioreviewedaccess_deniederror_handlingboundary
Worst case: a PATH-resolved fprintd-list runs attacker-controlled code as root during install or upgrade. access_denied: invoking /usr/bin/fprintd-list by packaged absolute path refuses any PATH-supplied substitute; the requirement is the refusal. error_handling: a probe failure or nonzero exit is treated as not-enrolled and routes to the removal branch, the fail-safe direction. boundary: the executable-bit check on the absolute path is the present-but-not-executable edge feeding the same removal branch. Catalog 1.11.0 re-review: input_domain not applicable, it invokes fprintd-list by absolute path and reads only its exit status. concurrency_scale not applicable, one probe per apply-lock run.
- propertynot applicable
One probe feeding one branch; no algebraic or repeated-application surface.
- structuralnot applicable
Fixed literal path invocation; no encoding, memory, or format-string surface.
- domainnot applicable
Local exec of a packaged binary under a restricted PATH; name_resolution_pre_chroot evaluated and not applicable: there is no chroot or sandbox entry, and the absolute path leaves nothing to resolution.

Enrollment query invokes /usr/bin/fprintd-list by absolute path only; PATH resolution is never used, matching fprintd_absolute_path_only.

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.

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.
