2026-07-10struct editor: C-style CRUD for local types (Ctrl+T)blasty
New StructEditor overlay: left is the list of local structs/unions, right is an editable C definition. Enter loads a struct (reconstructed as C from its member layout via type_inspect), Ctrl+S declares it (create or update via declare_type), Ctrl+N starts a new one, Del deletes, Esc returns to the list then closes. Domain: Struct model + Program.list_structs / struct_source / declare_type / delete_type (anonymous $-types filtered). Delete needs a 'del_type' tool the ida-pro-mcp server doesn't currently expose; delete_type detects its absence and reports a clear message instead of failing. Create/read/update work fully. Pilot checks: open, list, view C, create, update-in-place, delete(-or-report), close. full suite 84/84.
2026-07-09keep idle workers alive: bump_idle_ttl + KeepAlive heartbeatblasty
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.
2026-07-09domain/paging layer: FunctionIndex, block-cached DisasmModel, decompile, resolveblasty
- 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)
