Summary

Makes opening oma-cast and typing into it noticeably faster. Search results and rankings don't change.

• Persistent surface. LauncherWindow is now mapped once and kept. Mapping a fresh PanelWindow on every open cost about 150 ms of scene-graph setup. When hidden, the window is 1×1 px with an empty input mask and no keyboard focus. When shown, it grows to cover the monitor and takes Exclusive focus. While hidden it follows Hyprland's focused monitor, so it's already in place when you open it.
• Survives monitors going away. An output can disappear and come back under the same name, for example on lid close, suspend, or DPMS while locked. The window remaps when Quickshell.screens changes, so it doesn't get stuck on the dead screen, reporting "shown" but never drawing. I hit this on a laptop after a long lock.
• In-place row updates. rebuild() now diffs against a plain rowMirror and only sets the rows that changed, instead of clear() + append on every keystroke. Selection lookups read the mirror instead of rows.get().
• Ranker fast paths. These are memoized normalize/transliterate, per-candidate prepared text, a sparse fuzzy DP, a one-character shortcut, and a canSkip prefilter that RootSearch uses before decorating candidates. Scores and order are unchanged. The new tests/ranker-fast.test.js checks them against a dense reference DP. The new Ctrl+P root filter is applied in the prefiltered path too.
• Diagnostics. The new lastFrameAt IPC function returns the time of the first frame after the last show or hide. tests/smoke.sh uses it to time the open path end to end.
• Small fixes. oma-cast doctor no longer checks for socat, because omarchy-shell in 4.0.6 only uses qs ipc. The docs that described a socket fast path are corrected.

The branch merges current main and keeps the calculator, agent hand-off, vim/emacs bindings, argument pills, alerts, About panel and clipboard paste unchanged.

Numbers (Omarchy 4.0.6, Quickshell 0.3.2, Hyprland 0.56.2)

	before	after
show → first frame	59–66 ms (README)	24–41 ms
hide	24–42 ms	12–25 ms

Testing

• node --test tests/*.test.js: 108/108 pass
• tests/smoke.sh: all checks pass (doctor, IPC, root search, toggle latency under the 100 ms budget)
• Checked calculator (5 ft to cm), search, and the commands filter through oma-cast call rootSearch.search
• Not covered by an automated test: the monitor-dropout remap. The repro is to lock until the screen powers off, unlock, then open the launcher.
