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.
When the stranded-lock probe exits 0, the service holds no lock, and password PAM exists, the lock service shall take the session lock once.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When the stranded-lock probe exits 0, the service holds no lock, and password PAM exists, the lock service shall take the session lock once. It shall log a lock-stranded recovery event.
when stranded_lock_detected & password_pam_configured the lock_service shall eventually satisfy stranded_lock_recovered_once & recovery_logged

ext-session-lock outlives its client. Without recovery, a shell restart leaves an orphan lock that only the Hyprland failsafe covers and nobody can unlock.

Hazard review
- scenarioreviewederror_handlingconcurrentboundaryconcurrency_scale
Worst case: a shell restart leaves an orphan ext-session-lock nobody can unlock, or the recovery itself flaps, taking the lock repeatedly. error_handling: an undetermined probe answer (exit 2) leaves the strand unresolved instead of acting, and recovery refuses without passwordPamConfigured, deferring to the J8SX fail-closed denial. concurrent: checkStrandedLock refuses to probe while locked or lockRequested, and the probe onExited verdict re-checks the same flags, closing the probe-in-flight versus lock-taken race. boundary: recovered-once is the strandedLock plus strandedLockResolved latch. Catalog 1.11.0 re-review: input_domain not applicable, it reads no external text input. concurrency_scale applied, the recovery must take the session lock exactly once under repeated probe ticks.
- propertyreviewedidempotency
recoverStrandedLock is idempotent per strand: the flag pair plus the probe running guard make every repeated trigger, whether the screens-changed re-arm, the retry timer, or the PAM reload, converge on at most one beginLock and one journal line.
- structuralnot applicable
QML flags plus one guarded beginLock call; no memory, encoding, or numeric surface.
- domainnot applicable
In-process recovery plus a local probe process; no external call, transport, or trust boundary.

Re-recorded after the MC/DC annotation campaign shifted lines (checkStrandedLock 101->105, recoverStrandedLock 114->118). checkStrandedLock runs the probe once until resolved and short-circuits when the shell holds or requested a lock; recoverStrandedLock takes the session lock exactly once - the strandedLock=false reset guards re-entry - and only when the probe found no own lock and password PAM is configured, logging lock-stranded: recovering via logEvent before beginLock. Matches stranded_lock_recovered_once & recovery_logged.

Stranded-lock path matches: probe exit 0 + no own lock + password PAM configured takes the session lock exactly once and writes the lock-stranded recovery journal entry; the once-only guard prevents re-entry, matching stranded_lock_recovered_once & recovery_logged.

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.
