#541 fixed Android autocorrect duplicating the typed line in the primary
pane: xterm's keyCode-229 textarea diff is append-only, so an autocorrect on
space (delete a word, insert the corrected one) sent the whole line again.
The fix, an edit-based diff that sends one DEL per deleted code point and
then the inserted text, lives in terminal-keycode229-recovery.js together
with #441's next-keydown drain (a character committed in the same task as
Enter goes out ahead of the \r) and the original orphaned-insertText
recovery. Only the primary pane created that controller, so a grid tile or
the split's Pane B still ran xterm's stock behaviour. Both are gated on
width alone (1180 CSS px), which a wide Android tablet clears.
TerminalTile now creates its own controller in connect(), after the xterm
opens and before the first await, handed this tile's textarea, this tile's
CompositionHelper and _onTerminalData as the send path, so recovered bytes
go to the tile's own session through the exactly-once queue. As in the
primary pane, handleKeyEvent runs first in the custom key handler, above the
keyCode-229 early return, and notifyCanonicalData sits in the onData lambda,
gated on the same two CodemanTerminalInput predicates, never in
_onTerminalData, which the recovered bytes also take. destroy() tears the
controller down before disposing the xterm, which restores xterm's own diff
and removes the capture listeners. No mode or device gate, matching the
primary. The module itself is unchanged apart from its header; terminal-ui.js
gains only a comment naming the twin.
Tests: test/terminal-tile-input.test.ts now loads the real module into its
vm harness (with window timers, without which create() would silently throw
and every test would run against no controller) and drives a fake
CompositionHelper carrying xterm's own append-only diff. It covers install
and restore on the tile's own helper and textarea, autocorrect sent as an
edit (with a control reproducing the device-log duplicate), the last
character and an autocorrect each followed by Enter in one task, a
self-rescued 229 key delivered once, the onData gate ignoring query replies
and focus reports, two refused inserts after one keydown both recovered,
robustness when the controller throws, per-tile controllers, and a source pin
keeping the call above the early return. Removing the create, the
handleKeyEvent call, the notify, its gate, or the destroy each turns at least
one of them red, as does moving the notify into _onTerminalData. The browser
suite gains a TerminalTile block in
test/terminal-keycode229-recovery.browser.test.ts (real xterm, trusted
execCommand input, chunks asserted to address the tile's session, with a
destroyed-controller control).

terminal-tile-input defined FakeSocket, FakeFit and FakeTerminal inline;
they move unchanged to test/mocks/terminal-tile-fakes.ts so the grid's
load-queue test can drive a real TerminalTile on the same fakes instead of
its own near-copies. No assertion changed (a tile that never registers its
input socket still fails six cases).

TerminalTile carried its own copy of the smart-copy branch (clean the
selection with this session's gutter, copy, clear, toast). PR 1 gave
cleanedTerminalSelection and copyTerminalSelection a `{ terminal, sessionId }`
target for exactly this, and nothing passed it. The tile now calls both with
its own terminal and session, and its copy code is gone.
Two things change for a tile, both to the primary pane's rule: a clipboard
write that fails keeps the selection (nothing was copied, so it stays for a
retry) instead of clearing it, and focus returns to the tile's xterm after
the copy, which matters when the execCommand fallback focused a temporary
textarea. Pinned in terminal-tile-input with the write failing and
succeeding, and the no-selection Ctrl+C / Ctrl+Shift+C split.

A session Run makes while the grid is open joins as a tile right away, so
the tile connects and sends its size before Run starts the pane. The
server only records a resize for a session with no PTY and spawns the pane
at 120x40, and Run's own resize step measures the parked main terminal
(display: none, so nothing). Measured live for Shell and Claude: a 97x17
tile over a 120x40 pane, for good (#464).
The chrome refresh now remembers each tile's last-seen pid and calls
TerminalTile.paneStarted() when it appears or changes. paneStarted()
forgets the sent size and sends it; a hidden tile (a zoomed neighbour)
sends nothing and keeps it forgotten, so its next fit() sends it, which a
plain fit({ force: true }) would lose. Keyed on the sessions map, so a
handleInit after an SSE drop counts too.

When SSE comes back after a server restart, handleInit's reconnect
branch already re-opens the primary pane's socket; it now also calls
the split pane tile's reconnectNow(), so Pane B no longer waits out its
backoff (up to 10 s between tries) after every deploy. Live: Pane B was
back 4.6 s after the server process respawned, i.e. as soon as it
listened.

With the split open, every app-level terminal action resolved against
Pane A: Ctrl+L typed into Pane B cleared Pane A's display while xterm
sent the ^L into Pane B's PTY, and Ctrl+Shift+R restored Pane A's size.
_focusedPane() now answers with the terminal focused LAST (a mic or
header click moves DOM focus but not the user's pane): Pane B claims it
from its own textarea's focus, the primary terminal's focus gives it
back, and a destroyed pane never holds it. Ctrl+L, Ctrl+Shift+R, voice
dictation and image paste act on the focused pane. Ctrl+W deliberately
still closes the active session: it kills with no confirm, so moving it
is an owner decision (docs/tile-grid-plan.md, decision 5).
Also destroys every tile after each terminal-tile-input test: a real
reconnect timer from one test opened a socket in a later one and flaked
under full-suite load.

- Pane B registers the primary pane's file-path/URL link provider on
its own terminal, so a path an agent prints there opens the file
preview or log viewer for Pane B's session (it was plain text).
- Ctrl+V/Cmd+V in Pane B goes through the primary pane's paste trap,
aimed at Pane B: a pasted image uploads to Pane B's session and its
path is typed there; text keeps its bracketed-paste markers. xterm's
default handled text only.
Tests pin both the tile wiring and the targeted link provider itself
(registered on the target terminal, opening against the target's
session at click time, the primary's tap-path provider untouched).

- Font size, family and weight changes refit Pane B AND tell its PTY.
They used to reflow the xterm only, leaving the CLI wrapping at the old
column count, the garbled-redraw class #464 fixed for the primary pane.
- The resize frame reports the size the xterm actually holds, with no
40x10 floor (the divider's 20% clamp leaves about 28 columns), skips
an unchanged size, and is always re-sent on a fresh socket so it
re-registers as a desktop viewer.
- The server's {t:'zc'} geometry report is handled: a different column
count is adopted, rows stay local, using the primary pane's own
reconcilePtyGeometry verdict.

A Codeman restart (every deploy) or a network blip used to leave Pane B
dead, with a marker asking the user to close and reopen the split.
TerminalTile now reconnects:
- A transient close reconnects on the primary pane's backoff ladder
(CodemanWsReconnect) plus jitter; the attempt count resets only on a
successful open. The redelivery sweep's forced close (1005) counts as
transient.
- On reopen the closed state is cleared before the buffer refresh that
closes the output gap, so no stale marker lands under a healthy pane.
- 4003/4004/4009/4010 stop the pane for good and report once through a
new onExit(code) callback; the marker says why.
- Sockets are replaced race-free: the old one is detached before a new
one opens, and every handler ignores events from a socket that is no
longer current. destroy() cancels a pending reconnect.
- reconnectNow() lets an owner skip the backoff.

TerminalTile used to send every xterm onData chunk as a bare {t:'i'}
frame: no seq, no ACK, silently dropped while its socket was down, and
typing never acknowledged the session's idle alert. Keystrokes and
pastes now go through app._sendInputAsync over the tile's own socket,
registered in the input-socket map while open (HTTP fallback while
not), so they are ACKed, persisted until delivered, redelivered after a
drop, and the ACK clears the idle alert.
What xterm generates on its own stays out of that persisted queue: a
query reply (DA/CPR/OSC) is dropped, as the primary pane drops it, and a
focus or mouse report goes out once via _sendInputEphemeral. The tile's
socket carries the tab identity with a :tile suffix so it can never
evict the primary pane's socket.
