Summary

omacast setup hyprland rejects Alt+Space even after a user removes the default dictation binding with hl.unbind("ALT + SPACE"). Its recursive search matches both the unbind call and the disabled default.

 setup hyprland
-  scan config files for Alt+Space text
+  query active bindings with hyprctl -j binds
+  reject active conflicts before writing config

The check recognizes key names and keycodes, ignores unrelated modifiers and submaps, and allows reruns with an existing omacast or legacy oma-cast shortcut. If Hyprland cannot return a JSON binding array, setup exits without changing config.

Evidence

• Before the fix, the regression fixture with a default dictation binding and a user unbind failed with Alt+Space is already bound.
• After the fix, all 14 setup regression tests pass. They cover real conflicts, universal submaps, repeated setup, legacy migration, and unavailable or malformed binding output.
• node --test tests/*.test.js reports 152 passing tests, zero failures, and three skips.
• bash -n bin/omacast, omarchy plugin validate ., and git diff --check pass.

Merge danger

Door: two-way. Reverting restores the previous conflict check.

Blast radius: setup. Hotkey setup now requires a running Hyprland session. The README documents that requirement. Existing launcher behavior does not change.
