A full-height scrollable pager (the FloatBox analog) — porting it unlocks the
long-output slash commands (/status /logs /history /tools) at once (spec §2b).
- view/overlays/pager.tsx: bordered full-height overlay (title + scrollbox +
footer), scrolling driven explicitly via useKeyboard → scrollBy/scrollTo (no
reliance on scrollbox auto-focus), Esc/q/Ctrl+C close. §8 #2 scrollbox gotchas.
- store: pager state + openPager/closePager.
- view/App.tsx: content zone swaps to the Pager (replacing transcript+composer)
when store.state.pager is set; the close is deferred a tick so the closing key
can't leak into the remounting composer.
- logic/slash.ts: present() routes output to the pager when long (>180 chars or
>2 non-empty lines, Ink parity) else a system line; titled by command; /logs
always pages. New openPager on SlashContext.
Verified: bun run check green (41 tests / 7 files) — present() routing
(short→system, long→pager) + a pager frame test (renders title/content, replaces
the transcript/composer). LIVE tmux: /logs → pager (title "Logs", scroll via
PageDown, Esc closed → composer refocused, no key-leak); /version (5-line output)
→ pager titled "Version". Smoke P5a + parity matrix updated. Completions dropdown
+ pickers + chrome are the next slices.
