Desktop click-to-position-cursor died under the server's mouse-DECSET strip
(same root cause as the mobile touchend tap regression): xterm's native mouse
encoder only emits SGR while mouseTrackingMode is ON, but the server strips the
enabling DECSETs from claude/codex/gemini output. Hand-encode the report for
plain left-clicks (_handleDesktopTerminalClick), skipping every click that
already means something else (synthetic/compat, modified, double/triple,
drag-selection, off-grid, xterm encoder live).
Also widen forwarding to the wheel: Claude Code 2.1.187+ scrolls its own
transcript on SGR wheel reports and no longer captures wheel as select-menu
navigation (verified against 2.1.202), so forward the wheel to the TUI for
strip-mode sessions at the buffer bottom (40ms-coalesced to avoid a tmux
send-keys storm). Shift+wheel and any scrolled-up viewport stay on xterm's
local scrollback. Guard synthetic taps/clicks on viewport-at-bottom so a
scrolled-up report can't hit-test the wrong row.
Tests: 12 cases in test/terminal-touch-tap.test.ts. Verified E2E via Playwright
against the live instance (wheel up/down forward, Shift+wheel local, click).
v1.1.7 (3172bef, arrived via the master merge) strips mouse-tracking DECSET
sequences from claude/codex/gemini output so the wheel keeps scrolling
scrollback. Side effect: the browser xterm's mouseTrackingMode is permanently
'none' for those sessions, and the mobile touchend tap branch gates its
synthetic click on exactly that mode — so tap-to-position-cursor silently died.
Fix: when tracking reads 'none' but the session mode is one the server strips
(claude/codex/gemini — the PTY-side TUI still has tracking ON), encode the SGR
press+release report directly from the touch point and send it to the PTY,
bypassing xterm's mouse encoder. No DOM click is dispatched, so xterm's local
selection cannot trigger either.
Tests: 3 new cases in test/terminal-touch-tap.test.ts (SGR encoding, grid
clamping, shell-mode exclusion); verified E2E via Playwright iPhone emulation
against both a stripped-stream instance and the production bundle.
Three independent root causes of intermittent Chinese character loss
(English was unaffected because it bypasses the composition path):
1. input-cjk.js state machine: stuck _composing when compositionend never
fires (WeChat/Sogou IMEs) silently swallowed all input; the deferred
compositionend flush could reset the textarea mid-next-composition
(cancels the live IME composition on iOS); the 100ms keydown-echo
window discarded ANY input regardless of content.
2. Focus stealing: session-select / SSE-reconnect paths call
terminal.focus() (15+ call sites), landing focus on xterm's hidden
textarea; with the CJK onData gate active, everything typed there was
swallowed. Fix: focus router in initTerminal routes ALL
terminal.focus() calls to the CJK field while it is visible, plus a
self-healing onData gate that reclaims focus when it swallows input.
3. Android InputConnection wedge (9-key IMEs + Chromium): the keyboard
composes in its own UI but delivers zero DOM events. Fix: skip
redundant textarea value/selection writes (they race IME session
setup), and re-tapping the focused empty field forces a blur→focus
cycle that restarts the input session.
Diagnostics: input-cjk.js now traces every IME event/flush decision into
the crash-diag breadcrumbs; /api/crash-diag stores beacons per page-load
id (iOS PWA reloads no longer wipe the trail, concurrent clients no
longer clobber each other) and flushes on visibilitychange.
Tests: test/input-cjk.test.ts (vm-sandbox, 9 cases incl. regression
guards for all three root causes).
The mobile media query only overrode .response-viewer-body with a flat
font-size: 12px / padding: 12px, leaving the desktop response-viewer
typography system (--rv-content-max, .rv-text pre, heading scale) with no
mobile tuning. Bump body text to 14.5px/1.65, give code blocks phone-sized
padding and 11.5px code, scale headings (h1 1.35em / h2 1.2em / h3 1.08em),
let content span full width, and cap the panel at 92vh.
Layers cleanly on top of the existing response-viewer selectors in
styles.css; desktop rendering is unchanged.
touchmove fires on any 1px finger drift, marking didScroll=true and
skipping the tap handler (which refocuses terminal/CJK input). On
iPad's large touch surface and phones with imprecise taps, this makes
terminal tap unreliable — cjkActive gets stuck true, blocking all
input (CJK and paste).
Add 8px TAP_THRESHOLD: finger movement under 8px is still a tap.
Also add touch-action:none on .touch-device .terminal-container
so the browser doesn't consume touch events before our JS handler.
touch-action: none was only set inside @media (max-width: 430px),
so iPad's browser consumed touch events before the JS scroll/tap
handler could preventDefault. Move to .touch-device class in
styles.css so it applies at any screen width.
Reverts eb83148 which removed the /compact button from both simple
and extended accessory bar modes. Restores double-tap confirmation
and refocus guard for the compact action.
backdrop-filter on the toolbar creates a stacking context that traps
the popover's z-index (1000) inside the toolbar. CJK input (z-index 52)
in the root stacking context always wins. Use :has() to raise the
toolbar above CJK only while the popover is visible.
Move keyboard accessory bar and paste dialog CSS from mobile.css
(gated behind max-width: 1023px) to styles.css (always loaded).
iPad landscape (≥1024px) was getting unstyled white buttons.
- Add position:fixed via .touch-device class for accessory bar
- Fix dismiss button: gray-blue → blue, matching phone styling
- JS: position accessory bar above keyboard on iPad via direct bottom
- JS: position CJK above accessory bar (bottom: keyboardHeight + 44)
- Clear accessory bar bottom in resetLayout()
Phones use translateY(-keyboardOffset) — CSS bottom is relative to layout
viewport and keyboardOffset reliably lifts it above the keyboard (iOS
doesn't auto-scroll the visual viewport for the CJK textarea on phones).
iPad uses direct bottom positioning from keyboard height — translateY
broke because iOS auto-scrolls the visual viewport when the CJK textarea
receives focus, making keyboardOffset approach 0.
Three iPad-specific issues fixed:
1. CJK input hidden behind keyboard: updateLayoutForKeyboard() gate changed
from screen-size to touch-device detection. On iPad, CJK textarea (always
position:fixed) gets bottom offset computed from keyboard HEIGHT directly
instead of keyboardOffset (which depends on visualViewport.offsetTop that
iOS adjusts when the CJK textarea receives focus). Toolbar/accessory bar
transforms remain phone-only (they're normal-flow on iPad).
2. Paste dialog invisible on iPad: paste overlay CSS was inside
@media (max-width: 430px) phone breakpoint — iPad (≥768px) had no styling.
Extracted to universal section alongside keyboard accessory bar styles.
3. Voice dictation character duplication (Doubao/third-party IME):
iOS voice dictation does NOT fire composition events (WebKit Bug 261764).
Text arrives as bare input events; refinement is a delete→reinsert cycle.
Rewrote CJK input handler with two-tier debounce:
- Keyboard typing (no delete/replacement events): 150ms debounce
- Dictation mode (deleteContentBackward or insertReplacementText detected):
1500ms debounce, persists 3s to cover multi-word dictation
- Composition path (compositionend): immediate flush, unchanged
- Keydown singles/Enter/Esc/Ctrl: immediate, unchanged
Also: keep cjkActive=true on blur while CJK is visible (prevents xterm
from processing duplicate input when iOS dictation UI steals focus);
keydown single-char sends tracked via timestamp to suppress the echo
input event that third-party IMEs fire despite preventDefault.
Programmatic _textarea.value = '' during compositionstart cancels the
active IME composition on iOS Safari, breaking Chinese character input.
The phantom (U+200B) is invisible and _strip() already removes it
before sending to PTY — no need to clear it manually.
Root cause: the mobile-composer mode (02fa3f3) routed CJK text through
local-echo buffering, which accumulated characters until Enter instead
of sending each composed word to the PTY immediately. Additionally,
xtermFocusRedirect hijacked all terminal taps, preventing cursor
positioning and scroll interaction.
Changes:
- Remove mobile-composer accumulation mode from input-cjk.js — all
platforms now use the same immediate-flush path (compositionend →
flush → PTY)
- Bypass local-echo buffering in _handleCjkInput (terminal-ui.js) —
the CJK textarea already provides visual feedback
- Remove xtermFocusRedirect so terminal taps work normally again
- Reduce CJK textarea height (34px min, 6px padding) for less
screen intrusion
- Paste dialog now sends Enter after text so pasted content submits
- Hide CJK textarea on welcome screen (no active session)
- Add Opus 4.6 model options to selector
- Guard `_updateCjkInputState()` with `activeSessionId` check so the
`position: fixed` CJK textarea doesn't float over the welcome overlay
- Call `_updateCjkInputState()` in `showWelcome()`/`hideWelcome()` to
sync CJK visibility on session enter/leave
- Add `padding: 12px 10px` to `.cjk-input-visible textarea` for proper
vertical centering of input text
The header-right tray (02fa3f3) was reworked into a position:fixed
collapsible panel with a hamburger toggle, but the toggle button, its
JS, and CSS were later reverted on master while the container kept a
static `mobile-collapsed` class. With no expand mechanism left, the
header-right stayed display:none on mobile, so the response-viewer eye
icon was unreachable even with "Response Viewer" enabled — desktop was
fine because the media-query rule doesn't apply there.
Restore the simple inline always-visible header-right layout (dev's
known-good state). The showResponseViewer setting still controls the
eye's --hidden marker class.
Verified on iPhone viewport: eye visible (26x26) with setting on, hidden
with setting off, tap opens the viewer; desktop eye unaffected.
