Highlighting: Textual has NO C/C++ tree-sitter grammar (and the syntax extra
wasn't installed), so language='cpp' was a silent no-op. Replace TextArea with a
virtualized, Pygments-highlighted ScrollView:
- idatui/highlight.py: CLexer -> Rich styles, per-line Segment lists
- DecompView: lines highlighted ONCE at load, cached as Strips; O(1) scroll
Jank: profiling showed our code is ~3.6ms/move (render_line 0.018ms) -- the cost
was terminal repaint volume, since every cursor move refreshed the whole ~43-line
viewport. Now:
- cursor reactive repaint=False (no implicit full refresh)
- region-limited refresh: in-place moves repaint only the 2 changed rows
(measured 43 -> 2 render_line calls/move), full refresh only on scroll
Applied to both DisasmView and DecompView.
pilot suite 15/15 (adds highlighting assertion).

- idatui/app.py: keyboard-first Textual app
* FunctionsPanel: lazy-streamed function list (DataTable) with glob filter
* DisasmView: line-VIRTUALIZED ScrollView -- paints from domain block cache,
background-fetches misses, prefetches neighbors. Proven: 52,120-insn func,
jump-to-bottom in 0.31s with only ~6 blocks (~1.5k lines) ever materialized.
* address-history nav stack (Enter follow / Esc back); goto by name or 0xADDR
* bump_idle_ttl + KeepAlive on startup so the session never idles out
* all MCP work on Textual worker threads; UI never blocks
- idatui/tui.py: launcher (python -m idatui.tui / console script 'idatui')
- tests/test_tui.py: headless Pilot test, 9/9 (boot, load 10k funcs, open,
scroll, bg-cache, goto-bottom, filter)
- pyproject: textual extra + idatui script entry

thread-safe
- IDAClient: single handshake, ~7ms warm calls (vs ~60ms cold CLI)
- keep-alive connection pool over http.client; concurrent-safe (40 threads OK)
- grounded error taxonomy: IDAToolError on isError, soft per-item errors as data
- session-expiry recovery (404 -> re-handshake -> retry), bounded transport retries
- auto db-injection + resolve_db (ignores stale empty-id sessions)
- live smoke test: 13/13 pass
