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 prelude's omarchy-pkg-present/missing shadows agree with pacman -Q everywhere.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
The prelude's omarchy-pkg-present/missing shadows agree with pacman -Q everywhere. This covers provides resolution, version constraints deferred to pacman, and the no-argument case (present true of nothing, missing not).

Hazard review
- scenarioreviewedboundaryedge_caseerror_handlinginput_domain
Worst case: pacman -Qq fails (broken db) and stderr is suppressed, so the mapfile seeds empty and every plain package name reads missing - Install rows flip to installable and already-installed marks vanish; consequence is wrong UI state until the next open, with no destructive action firing automatically (installs are user-clicked) and the guarded verb re-evaluating each refresh. boundary: the no-argument case is pinned by contract - present of nothing is true (vacuous all-loop), missing of nothing is false - and the tested half matches the implementation exactly. edge_case: provides entries are extracted by the awk field split with version operations stripped, multi-provide lists split on spaces, and the literal None skipped; version-constraint arguments (containing <,>,=) bypass the snapshot and defer to a live pacman -Q, so a mid-session install makes constrained args fresh while plain names stay snapshot-stale - bounded staleness inherent to the one-shot mapfile design. error_handling is the declared class: the all-missing degrade above is the failure mode, silent but recoverable and UI-level. Catalog 1.11.0 re-review: input_domain applied, it reads pacman -Q answers through the prelude shadows; the producer emits machine-generated text and only the exit status decides. concurrency_scale not applicable, a pure function of its arguments, recomputed on each load or keystroke: no state across calls, no process, timer or lock.
- propertyrevieweddeterminismtotality
determinism: the shadow map is a pure function of the pacman database state at read time - same db, same answers, sorted input order irrelevant to the associative array. totality: every (argument list, argument form) combination resolves to one boolean - snapshot hit, live constraint check, or plain miss - with no form falling through undefined, and the no-arg extremes pinned.
- structuralnot applicable
Generated bash with quoted expansions, literal associative-array keys, and a character-class test routing constraint forms to pacman; no eval of package names, no arithmetic, no encoding transform - names with glob metacharacters are impossible in arch package names.
- domainnot applicable
Read-only pacman queries against the local package database; -Q takes no database lock and performs no network access, and the shadow adds no authority - it only answers what pacman would answer, faster.

Read guardHelpers. The prelude builds __omarchy_pkgs from pacman -Qq plus parsed Provides entries, and __omarchy_pkg_has falls back to pacman -Q for version-constrained names, so omarchy-pkg-present/missing agree with pacman -Q including provides resolution and the no-argument case. pkg_presence_asked models calls to the shadows; shadow_matches_pacman is the cache-plus-fallback construction. Formula conforms to the code.

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.
