mode is cycle/back/show or an explicit format. 'show' reports the current
format and the stops on offer without editing, which is what a driver
needs: the rendered text alone can't be trusted (a listing read before an
ARM/Thumb switch shows the old decoding). 'word' puts the cursor on a
token first, so a literal can be named instead of steered to.

Two bugs found driving a 65KB ARM firmware image (one flat 42k-line listing, no
ELF sections to break it up):
`note` did goto + `cursor line=0` before commenting. Line 0 is the top of the
function only in the DECOMPILER; in the listing it is the top of the SEGMENT, so
every note landed at address 0 -- and scrolling a 42k-line listing there took so
long the call timed out, which read as "comments are broken". goto already lands
on the function's first line, so the cursor call just goes; note now also
reports where it landed.
The client's 90s timeout was too tight for the same reason: comments on that
listing take 26-106s (the rebuild has no function boundary to stop at), so the
CLI reported "no response ... server busy or the op is hung" for edits that had
already been applied. Believing a successful edit failed is the worse error --
the driver redoes it, or "fixes" what was never broken. Default is now 300s;
IDATUI_RPC_TIMEOUT still overrides.

Opening a headerless blob was the one workflow that fell out of the driving
surface entirely, and each gap hid the next:
- `pane spawn` couldn't pass --processor/--base/--ida-args, so the pane came up
"ready" with zero functions (x86 at 0) and the only way through was to
hand-write a project file. It now forwards them to idatui.launch.
- c/p/t/T (code, function, ARM<->Thumb, vector scan) existed as listing
bindings with no verb, so a driver had to guess raw keys -- and raw keys are
swallowed by whatever modal happens to be up. `define {kind,target?}` goes
through the app's own edit worker and reports what IDA actually did.
- every name went through the typed rename prompt: a navigation (listing page +
decompile) plus two prompt round-trips each. A 427-symbol map took tens of
minutes of driving. `rename_many {items|file}` hands IDA's rename tool the
whole list in one call (371 symbols in 3s) and refreshes the caches and the
function table once.
drive gains `define <kind> [target...]` and `syms <file.json>`.
Verified live against a real pane (tests/test_rawimage_rpc.py, 13 checks:
spawn load options, define thumb/func + unknown-kind rejection, rename_many
from a file and inline, with resolve/functions readback).

Three things, all following from phase 3 making cross-binary jumps ordinary.
**A cross-binary jump was a one-way door.** Nav history is per-binary, so
arriving in another binary — a project search hit, or now following an import
into the library that implements it — landed you in an empty history with nothing
to take you back. _switch_then_goto records the binary it came FROM, and
action_back falls through to that hop once local history is spent: Esc walks back
through the function you were in, then the binary you were in. Manual Ctrl+O
switching records nothing, because that isn't navigation.
**Pre-warm follows the linkage graph, not list order.** _prewarm_provider warms
the binary providing the most of this one's imports — where a follow is most
likely to go, so its startup is paid before you ask for it. "Next in the list"
would have been arbitrary; phase 3 gave us something better to ask.
pool.prewarm() refuses rather than making room. Evicting a binary the user
visited to speculatively load one they haven't is a straight downgrade, and it
throws away that binary's caches as well; at a tight budget pre-warm just does
nothing. The cost of a worker that doesn't exist yet can only be estimated, so it
uses the largest resident one (same program, different database) — and if that
estimate proves wrong, the speculative worker is the one evicted, never a chosen
one.
**Driving a project.** pane spawn --project FILE [--open BIN]; `binaries` lists
the inventory (active / resident / indexed / where Esc returns to) and `switch
{binary,addr?}` makes another active — with an address it takes the search-hit
path, so it records a hop. state gains `binary` and `hops`, which it should have
had the moment project mode existed.
Verified on real sessions: drive binaries/switch against an echo+cat project
pane; Esc crossing back from a switch; and prewarm on echo+libc picking libc
(provider of echo's imports) and warming it after an evict.
tests: +5 pool (prewarm warms, no-ops when resident, refuses at budget, evicts
nothing when refusing, ignores unknown labels) and +4 project UI (jump records
the hop, Esc crosses back, hop consumed). Confirmed the Esc-back checks fail with
the branch removed. 195/0 scenarios, 27/0 project UI, 36/0 index, 27/0 pool,
33/0 project.
Left open: project-level persistence across sessions.

The pc command called only the read-only pseudocode RPC (runs off the UI
loop, never touches the screen), so LLM-driven sessions showed nothing on
the live pane. Compose goto + toggle_view + search so the real TUI
navigates to the function, makes the decomp pane the visibly-active view,
and jumps the cursor to the needle — then return the same text as before.

Round out idatui.drive with 'save' and 'retype <fn> <proto>' so the whole
common RE loop (orient/understand/act/persist) has a terse command. Update
docs/RPC.md and both skills (idatui, idatui-rpc) to recommend idatui.drive
as the day-to-day driving surface, with rpcclient/raw as the fallback for
unwrapped verbs.

Driving via rpcclient meant re-exporting the socket every fresh shell,
long invocations, and piping ~every call through python -c to pull one
field or grep pseudocode. idatui.drive fixes that: it auto-resolves the
socket (the single live pane from the registry), prints compact text
instead of JSON, and bundles the common gestures:
where | go | pc <fn> [substr] | dis <fn> [n] | callees/callers <fn> |
names <substr> | rename <old> <new> | mv old=new... | note <fn> <text> |
screen | raw <method> k=v
So 'goto+rename+parse' becomes 'drive rename old new', and 'pseudocode |
python -c grep' becomes 'drive pc fn needle'. rpcclient stays the raw
transport. rpc_smoke drives it end-to-end (29 green).
