Omarchy

ProbeLabsviewing a historical run

A 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.

Specification

The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.

Description

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.

FRETish formula
when fingerprint_enrollment_queried the apply_lock shall always satisfy fprintd_absolute_path_only

Rationale & tags

Why this requirement exists, and how it is categorised.

A PATH-resolved fprintd-list would run attacker-controlled code as root during install or upgrade.

  • 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.

Open known issues

Findings currently open against this requirement — issues its verification surfaced that are not resolved yet. Each links to the full finding.

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.
