- action_toggle_functions: collapse/restore left pane, disasm takes full width;
focus follows (disasm when hidden, table when shown)
- pilot test covers the toggle (11/11)

- 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

Root cause: idalib workers run an idle watchdog (worker_lifecycle.py) that
self-exits after idle_ttl_sec (default 600s) of no requests -- deliberate
resource hygiene for a shared/ephemeral supervisor, wrong for an interactive
TUI. CLI-opened startup binary always gets 600s (no flag).
Fix (both verified against a 12s-TTL session):
- IDAClient.bump_idle_ttl(1e9): re-open (idempotent) re-applies TTL, no upper
cap -> effectively immortal. Primary fix, call once at startup.
- IDAClient.keepalive()/KeepAlive: background server_health heartbeat resets the
watchdog; covers adopted sessions too. Safety net.
tests/test_keepalive.py: 4/4 (heartbeat + bump both keep a short-TTL worker
alive past 2x TTL). docs updated with why + fix.

- Program: model registry + small prefetch pool; cache invalidation hooks
- FunctionIndex: lazy pagination (advance by len, clamp page=500), filter globs,
viewport windows; full 10,092-func enumerate matches survey in ~3.1s
- DisasmModel: block-cached windowed disasm (256/block), forward+back prefetch,
cached instruction totals; deep window revisit 196ms -> 0ms (cache proven)
- Decompilation: truncation-aware, hard-failure surfaced as data (monster funcs)
- resolve(): int/hex/symbol via lookup_funcs (string-array query shape)
- tests/test_domain.py: 17/17 on both ls (~290 funcs) and libcrypto (10k+52k-insn)
- smoke_client no longer assumes 'main' exists (works on libraries)
- doc: idle_ttl worker self-exit finding ("not reachable" needs re-open)

- auto-recover stale db ("Session not found" after server restart): drop pin,
re-resolve sole session, retry once. Only when db was auto-injected; never
silently switches an explicitly-pinned db (auto_recover_session gate).
- tests/serverctl.sh: start/stop/kill9/ready control over spawn.sh
- tests/stress_client.py: 6 adversarial scenarios, 24 assertions:
dead-port fail-fast, tight-timeout recovery, worker crash, full restart
(naive auto-recovery + no-autoswitch), 300/16 concurrency, kill-under-churn.
All clean: no hangs, no deadlocks, no non-IDAError leaks.
