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.
Non-positive sleep-lock budget for logind windows <= 1s: suspend proceeds with no lock attempt
Medium-severity issue, currently open.
Description
The issue as recorded.
derive_budget_ms reserves max(window/5, 1000ms) with no floor (bin/omarchy-system-sleep-lock:37-40): a 1s InhibitDelayMaxUSec yields budget 0 and any sub-second window yields a NEGATIVE budget. The line-45 heal guard re-derives instead of flooring - a second identical busctl read that reinstalls the same illegal value. With budget <= 0 the deadline is already past, so every lock_ipc hits the remaining<=0 guard and returns 1 with empty stdout. request_lock's case then silently falls through. The machine suspends with the lock NEVER attempted - only a 'within 0ms' notification marks it.

What protects you, and the fix
What limits your exposure today, and the planned remediation.
What protects you now
default 5s window stays unaffected; only logind drop-ins with windows <= 1s hit the chain
The fix
Floor the derived budget at 1ms (or clamp the reserve to window-1ms). Make the heal guard substitute a safe constant instead of re-deriving. Surface lock_ipc's refusal instead of swallowing it
Blast radius
If you touch this issue, what else may need re-checking — the requirements it affects and the code and tests that hang off them. Historical view: authored trace links only — automatically derived links aren't reconstructible for past runs.
No authoredcode links reach these requirements in this historical reconstruction. Automatically derived code links aren't reconstructible for past runs, so implementing code may have existed without an authored trace.
