Review of #268 turned up two defects, both verified against a real shell
session on an isolated instance.
1. A tap spent the modifier. The onData hook consumed every chunk while
armed, but not every chunk is a keystroke: a shell session keeps the
narrow scrollback strip, so mouse DECSETs reach the browser, and with
vim/htop running a tap arrives as `\x1b[<0;31;23M`. Measured in the
real app: armed, one tap, disarmed, and the Ctrl button read as dead.
The hook now skips mouse and focus reports via a new
`CodemanTerminalInput.isTerminalFocusOrMouseReport()`; they still reach
the PTY, they just no longer stand in for the next key. Focus reports
are covered for the same reason even though FOCUS_ESCAPE_FILTER in
session.ts strips DECSET 1004 today, since the bar refocuses the
terminal after every key and would spend the modifier on its own
`\x1b[I` the moment that filter changed.
2. The armed style did not land on the four light skins. The competing
rule is (0,3,1), not (0,2,1) as the comments claimed: `:is()` takes the
specificity of its most specific argument and that list holds
`.btn-toolbar.btn-shell`, so it outranked the (0,3,0) armed rules in
both stylesheets. Measured across all seven skins at 390px, armed and
resting backgrounds were byte-identical on paper-gray, solarized-light,
catppuccin-latte and rose-pine-dawn. The light-skin rule now excludes
the state as `.accessory-btn:not(.armed)`, which fixes phone and tablet
at once; adding another class to the armed rules would only have moved
the tie.
Tests: 20 more cases in test/mobile-shell-keyboard.test.ts (the report
classifier, the gate's effect on the modifier, and a static guard on the
light-skin selector, since the existing E2E background assertion passes on
a light skin and the browser suite runs the dark default), plus a browser
regression that taps the terminal with mouse reporting on.

The mobile accessory bar was built around coding-agent commands, so a shell
session had no way to send Ctrl chords at all.
A shell-mode session now gets its own bar automatically: Ctrl, Esc, Tab,
four arrows, paste, dismiss. Agent sessions (claude, codex, opencode,
gemini, antigravity) keep the existing bar unchanged.
Ctrl is a one-shot modifier: tap it and it lights up, the next character
typed on the system keyboard is sent as its control byte, and Ctrl disarms.
Tapping it again cancels. That puts Ctrl+C/D/Z/R/L/A/E/W/U/K on a
nine-button bar without a button per chord.
Implementation notes:
* The interception lives in terminal.onData, not a keydown handler: a
virtual keyboard reports no usable key events, so the character only
exists as onData text. It sits after shouldSuppressTerminalQueryResponse
(xterm answers DA/CPR queries through onData too, and letting one of those
spend the modifier would silently eat the user's Ctrl) and before every
send path, so the control byte follows the normal control-char route.
* ctrlByteFor() maps `code & 0x1f` over @A-Z[\]^_ and a-z, plus
Ctrl+Space = NUL and Ctrl+? = DEL. Characters with no control equivalent
pass through unchanged, like a hardware keyboard.
* The bar now separates the base layout (the extendedKeyboardBar setting)
from the effective one, resolved per session by refreshForActiveSession().
A settings save during a shell session cannot yank the bar away, and
switching back to an agent tab restores the user's choice.
* Ctrl disarms on use, a second tap, any other accessory key, a session
switch, keyboard dismissal and a layout swap.
* Ctrl joins the refocus set, so tapping it keeps the terminal focused and
the keyboard open.
* The armed style needs three classes to outrank mobile.css's light-skin
.accessory-btn rule at (0,2,1).
Verified end to end against a real shell session on an isolated instance:
tapping Ctrl then typing c interrupted a running `sleep 300` (^C in the
pane), the modifier disarmed, plain typing stayed literal, Ctrl+L cleared,
and a cancelled Ctrl typed a literal c.
Tests: test/mobile-shell-keyboard.test.ts (new, runs in CI) covers the
mapping table, layout selection per session mode, base-mode memory and every
disarm path; test/mobile/keyboard.test.ts adds nine browser regressions that
drive the real xterm with page.keyboard.type() and assert on the bytes that
would go out.
Closes#262

selectSession() ends with scrollToLastNonEmptyLine(), which parks the viewport
one row ABOVE the bottom for any session whose buffer is taller than the screen
and ends in blank rows, so that is the normal state after a tab switch. Nothing
pinned that a tap there still leaves the keyboard reachable.
The blocker reduced in #173 came back through exactly that gap in #244: a tap
classifier that treats "viewport is scrolled up" as a reason to blur, paired
with touchstart preventDefault cancelling the compatibility click, closes both
routes to focus on the same gesture and strands document.activeElement on
<body> with no way to type. The prompt row is no exception.
Measured on a 390x844 viewport, claude-mode session, dispatched touch gesture:
master leaves focus on textarea.xterm-helper-textarea, PR #244's terminal-ui.js
leaves it on body. Green here, red against that branch.
The test also pins the half that IS correct: SGR coordinates are meaningless
off-bottom, so the tap must send no mouse report.
It has to be a dispatched gesture. Calling the touchend handler directly
bypasses touchstart's preventDefault, which is half of what closes the focus
path, so a direct call reports the right intent and still misses the bug.
test/mobile/keyboard.test.ts: 4 failed | 32 passed (36), against 4 failed |
31 passed (35) without it. Same four pre-existing failures either way.

The working dot is the one glance-state a phone needs: busy tabs now get a
9px pulsing dot with a green glow (idle stays 4px). The glow needs !important
because the skin block's no-halo rule outranks mobile.css.
The simple keyboard accessory bar swaps /clear for Tab (/clear and /compact
stay in the extended bar with their double-tap confirm). The tab action now
flushes locally-buffered prompt text to the PTY before sending \t, so
completion applies to what was just typed instead of an empty composer.

terminal-ui.js: _localEchoPolicy ('buffer'|'predict'|'off') computed at the
end of _updateLocalEchoState with _localEchoEnabled keeping its exact 1.12.2
values; _predictHookOnData called as a plain statement between the buffer
block and Normal Mode (visual-only, try/catch, never returns, never touches
_pendingInput); classifyPredictInput + isCodexComposerRow (baseY-based,
measured /^> /-signature gate) on CodemanTerminalInput; construction beside
the LocalEchoOverlay from the separate bundle with graceful absence;
insertTerminalText/clearTerminalInput/setFontSize/applyTerminalSkin clear or
refresh predictions. app.js: fields + tab-switch and SSE-reconnect clears.
voice-input '\r' branch and keyboard-accessory sendKey clear predictions
(both bypass onData). sendEnterKey needs no change: codex falls through to
the immediate-flush branch.
Layer 4 vm tests: classify truth table (20 cases), composer-row gate incl.
the baseY pin, policy matrix with the 1.12.2 invariants untouched, wire
neutrality + throwing-predictor pins. Stale mobile keyboard codex-buffering
tests repointed at claude; new codex twin asserts write-through streaming,
prediction spans and TTL self-heal.

A visualViewport resize event without a pending show/hide transition now
only pushes a pending settle back (_deferViewportSettle) instead of arming
fit + PTY-resize work of its own. Keyboard detection can miss a
fine-grained OS animation entirely (each step under 150px, with the
baseline chasing the animation down), while MobileDetection's own listener
still shrinks --app-height, so the per-event settle fitted xterm against a
mid-animation container with no keyboard CSS compensation and resized the
PTY to transient dims. The resulting SIGWINCH thrash (58 -> 10 -> 50 rows)
duplicated prompts and left tmux dot filler in the transcript on keyboard
close. Reproduced with a faked visualViewport driving the real handler;
master is unaffected because it never resized the PTY from this path.

The suite never selects a session, so initTerminal() does not run and both
`app.terminal` and `app.fitAddon` are null at rest. `_scheduleViewportSettle`
returns early on a falsy terminal, so the coalescing assertions could not
reach the behavior they claimed to cover -- the test errored on
`Cannot read properties of null` rather than measuring anything.
Installs the minimum surface the settle callback touches and restores it
afterwards, so the coalescing path executes for real.
Adds a behavioral counterpart driven through the PUBLIC entry point
(`onKeyboardShow`) instead of the internal scheduler: three viewport steps
in quick succession must produce exactly ONE refit. On master that returns
3 (each show arms its own uncoalesced 150ms timeout), so this fails by
COUNT rather than by a missing method -- which is the failure mode that
actually demonstrates the bug.
Verified: `expected 3 to be 1` on unmodified master; passes here. The
remaining 8 failures in this file are pre-existing on master and unrelated
(same null-initialization limitation of the headless harness).
The PR gates CJK textarea visibility on an active session
(`showCjk = cjkUserEnabled && !!activeSessionId`) so the fixed-position textarea no
longer floats over the welcome overlay. That intentionally changes the behavior the
existing `shows the CJK textarea on mobile only for server override` test asserted —
it set `_serverCjkOverride = true` on a fresh page (no active session) and expected the
textarea visible, which now (correctly) resolves to hidden. The test lives in
test/mobile/** (excluded from CI), so it wasn't caught by the PR's green CI.
Update the test to verify the new, intended behavior: with the server override on it
stays hidden on the welcome screen (no active session) and is revealed once a session
is active. This is a co-authored review fix; the original change is TeigenZhang's.
Verified: tsc, check:frontend-syntax, check:public-assets, prettier all clean.

Mobile-focused fixes for the web UI: keyboard-accessory layout and
overlap, native input visibility above the keyboard, CJK input handling,
terminal touch scrolling, tab-menu tap targets, mic-recording glow
containment, and mobile resize/keyboard-state handling on tab switch,
plus mobile visual-regression test coverage and snapshots.
