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.

Known issueKI-MENU-CLI-EXIT-CODE-WRITE-RACES

Contracted exit codes lost when the usage/diagnostic write fails: unknown verb exits 1, help exits 1

OpenOpenLow

Low-severity issue, currently open.

Description

The issue as recorded.

Under set -e, the unknown-verb diagnostic (bin/omarchy-menu:50-52) and the help heredoc (34-35) abort the script when their write fails. With fd 2 closed an unknown verb exits 1 without reaching the canonical exit 2. With fd 1 closed help exits 1 and never reaches exit 0. Callers that distinguish usage errors (2) from generic failure (1) misclassify, and help loses its promised success.

The fix

Guard the writes (echo ... >&2 || true; exit 2; and cat >&1 || true; exit 0) so the contracted exit status survives a failed write
