Cmd-P opens a modal transient palette over the writing column: a bare
fuzzy-search input, the ranked file list, and the selected row in reverse
video. A pure host-testable fuzzy_score (subsequence + word-boundary and
consecutive-run bonuses) ranks results; an in-core MRU floats recently
opened files first and is shared with :e (both route through open_path).
The host feeds the file list once at boot (enumerate_files over /sd/repo
and /sd/local). Ctrl-n/Ctrl-p navigate the list; Enter opens via the same
park/evict path as :e; Esc closes.
Ctrl-n/Ctrl-p also become down/up line motions in Normal and View (vim
CTRL-N/CTRL-P, count-aware), which is why the palette opener is Cmd-P
alone. No `>` prefix on the file input — `>` is reserved for the command
palette (slice 4).
112 editor + 28 keymap tests; the no-git firmware binary builds clean.

load-bearing choices, or the v0.1 specs for what the
first release actually does.
