The prior wording claimed the no-op stub was kept so SSE idle/working
handlers could call it without guards, but there are no callers anywhere.
Reword to reflect that it's a vestigial, intentionally-retained guard
documenting why Ctrl+L must not be auto-sent. Comment-only; minified
build output is unchanged.

Claude Code 2.x treats Ctrl+L (\x0c) as a two-step "clear conversation"
command (first press shows the confirmation prompt, second press
clears). The frontend previously fired \x0c from three places to force
Ink to redraw stale CUP-positioned frames in the tailed buffer; if a
page refresh or SSE reconnect ran the same path twice within Claude's
confirmation window the second \x0c silently nuked the user's
conversation.
Removed the \x0c sends from:
- selectSession() — main offender, runs on every tab switch & page reload
- restoreTerminalSize() — manual "restore size" button
- sendPendingCtrlL() — dead code path (pendingCtrlL was never populated)
Trade-off: occasional stale Ink frames immediately after refresh; the
user's first keypress causes Ink to redraw and the artifact vanishes.
Losing the conversation silently is far worse than a brief cosmetic
glitch.

Drill into a single project's complete history when the homepage's
3-per-project dedup hides older conversations.
- Backend: /api/history/sessions accepts projectKey/offset/limit;
single-folder mode bypasses the 50-cap and returns { sessions, total }.
projectKey is validated against ^[A-Za-z0-9_-]+$ to prevent traversal.
- Frontend: detail panel adds "View all in this folder" button that
opens a modal listing 20 sessions per page with Show more pagination.
- Modal items reuse _buildHistoryItem with showViewAll:false to avoid
recursive entry points.

Previously the client cached open session tabs in localStorage and resurrected
any that the server no longer knew about as grayed-out "ended" stubs. On
multi-device use (close tab on mobile, open desktop) this left stale phantom
tabs the user had to manually dismiss.
Remove _restoreEndedTabs / _saveTabMetadata, the session._ended branch in
selectSession, the data-ended render attribute, and the matching CSS rule.
Clear the legacy localStorage key on init to purge stale entries.

Closes#89.
- _disposeWebGLObserver() called from both trip path and onContextLoss (fixes the leak)
- Thresholds (200ms/3/30s/5s/7d) hoisted to WEBGL_FALLBACK in constants.js
- Pure evaluateWebGLLongTaskTrip() helper + 9 Playwright tests (test/webgl-fallback.test.ts, port 3166)
* feat: add image paste and drag-and-drop support
Clipboard paste (Ctrl+V) and drag-and-drop of image files into the
terminal. Images are saved to {workdir}/.claude-images/ and the
absolute path is inserted into the terminal input for Claude to read.
- POST /api/sessions/:id/paste-image endpoint (hand-parsed multipart)
- image-input.js mixin with paste trap technique (works on HTTP)
- Ctrl+V intercepted at xterm keyboard level, routes through hidden
contenteditable div to capture both image and text clipboard data
- Drag-and-drop on terminal container with visual overlay
- Session cleanup deletes .claude-images/ on destroy

* security: remove SVG from paste-image allowlist
Drops .svg / image/svg+xml from the paste-image endpoint. SVGs are
served as image/svg+xml via /api/sessions/:id/file-raw, same-origin,
under a CSP that permits inline scripts — which would execute on view.

The xterm WebGL renderer can stall the main thread for hundreds of ms
under GPU pressure (driver hiccup, integrated-GPU memory pressure,
hardware-accelerated browser layers contending for the GPU). Symptom:
the page becomes intermittently unresponsive and Chrome eventually
shows the "Page Unresponsive" dialog. Today the only mitigation is
?nowebgl, which the user has to remember and re-apply on every load.
This patch installs a PerformanceObserver after WebGL init that
watches for sustained main-thread stalls and falls back to the DOM
renderer automatically:
- Threshold: 3 long tasks of >=200ms each within a 30-second window.
- 5-second grace period after init skips the noisy initial-load
stalls so a slow first paint does not trip the guard.
- On trigger: dispose the WebGL addon, write a sticky disable to
localStorage with a reason and timestamp, and refresh the terminal
so the canvas renderer takes over without a page reload.
- Subsequent loads honor the sticky disable for 7 days, then auto-
expire so users retry after a driver/Chrome update.
- Force re-enable any time with ?webgl=force (also clears the
sticky entry).
- Existing ?nowebgl behaviour is unchanged.
- The same disable path is reused by the existing onContextLoss
callback so a hard context loss also persists across reloads.
Files:
- src/web/public/app.js: _initWebGL onContextLoss now persists +
schedules the watchdog; new _installWebGLLongTaskGuard and
_disableWebGLSticky helpers.
- src/web/public/terminal-ui.js: WebGL init checks the sticky entry
with 7-day expiry, honors ?webgl=force, threads sticky into
skipWebGL alongside the existing mobile + ?nowebgl gates.
PerformanceObserver longtask is widely supported (Chromium, Edge);
the try/catch around .observe() makes Firefox/Safari (which lack the
longtask entry type) silently no-op and just keep WebGL.

When the data-pacing path (chunkedTerminalWrite + deferred path of
flushPendingWrites) schedules its next chunk via requestAnimationFrame
alone, terminal output stalls indefinitely if rAF is starved. Three
real-world scenarios reproduce this in Chromium:
1. Window is occluded (fully covered by another window, or on a
monitor that has gone to sleep). rAF drops to ~0Hz.
2. Tab is idle-throttled (no user interaction for ~5 min). Chromium
intensive-throttling clamps setTimeout to 1Hz too.
3. Tab is in a background window. Both rAF and setTimeout slow to a
crawl.
Replace the rAF-only scheduling with a _safeYield helper that races
three primitives in parallel:
- requestAnimationFrame (primary, fires at compositor rate).
- setTimeout(50) (fallback for visible-but-occluded windows).
- Worker postMessage tick (fallback for idle-throttled and
background tabs; Workers are not subject to main-thread throttling
— this is the React Scheduler trick).
The first one to fire wins via a `done` guard; the others become
no-ops. The Worker is built lazily on first call (4 lines of inline
JS via Blob URL); if Worker construction throws we silently fall
back to the other two primitives.
Replaces 6 requestAnimationFrame callsites that participate in data
pacing:
- 3 flushPendingWrites scheduling sites (live + deferred paths).
- 3 chunkedTerminalWrite sites (initial chunk, next-chunk loop,
final finish-callback).
True animation use cases (scroll loop in scrollToBottom, fit-addon
reflow) stay on plain requestAnimationFrame — they are correctly
throttled when the user is not looking, by design.
File: src/web/public/terminal-ui.js (+70/-8).

Default layout was a single nowrap row with path + date + size, which on
narrow screens truncated both the first prompt and the directory suffix
(where project names actually live). The /Users/ home shorthand was also
never applied on macOS.
Changes:
- Title now uses 2-line clamp so more of the first prompt is visible.
- Subtitle resolves workingDir against known cases: exact match shows
"#caseName", subpath shows "#caseName/sub", otherwise falls back to
basename. Case labels are styled distinctly.
- Normalize both /home/<user>/ and /Users/<user>/ prefixes to "~/".
- Each history item gets a "..." toggle that expands an in-place detail
panel with the full prompt, full path, timestamp, size, and short
session id. Collapses back on second click; clicking the card body
still triggers resume.

CLAUDE_CODE_EFFORT_LEVEL (and any CLAUDE_CODE_* / OPENCODE_* key) now flows:
UI dropdown → POST /api/sessions { envOverrides }
→ new Session({ envOverrides })
→ this._envOverrides
→ tmux-manager.buildEnvExports appends `export KEY=<shellescape(VALUE)>`
Previously the API wrote envOverrides to <case>/.claude/settings.local.json, which
created stale state (UI dropdown disagreeing with disk) and polluted user project
directories. Now envOverrides are ephemeral spawn-time state, preserved across
respawnPane cycles via this._envOverrides and across server restart via
SessionState.envOverrides in state.json.
Also removes the now-unused updateCaseEnvVars import from session-routes.ts.
On Android tablets, pressing Shift+A produces "AA" because the input
event listener re-sends characters that xterm already processed via
its keydown handler. Track keydown timestamps and skip input events
that fire within 50ms of a handled keydown.
Only affects touch devices (listener gated by isTouchDevice()).
- Show Codeman logo on mobile as compact home button (was hidden)
- Add "Show More" button for history sessions (initial 4, expand all)
- Deduplicate by projectKey instead of workingDir (lossy decode fix)
- Fix project key decoding: handle '_' encoded as '-' with look-ahead
- Pre-validate resumeSessionId before passing to Claude CLI
- Apply content validation to all session files regardless of size
Three fixes from the WIP flicker branch that were lost during master merges:
1. Move viewport clear (\x1b[3J\x1b[H\x1b[2J) inside the dimension-change
guard so it only fires when cols/rows actually change. Previously every
resize event cleared the screen even at identical dimensions, causing
visible flicker with no subsequent Ink redraw to repaint.
2. Sync _lastResizeDims in sendResize() so restoreTerminalSize() doesn't
trigger a redundant viewport clear on the next throttledResize tick.
3. Add didScroll tracking to touch events — tap (no scroll) now refocuses
xterm's hidden textarea, fixing mobile keyboard input routing after
tapping the terminal area.
Terminal flicker:
- Skip buffer-recovered/clear-terminal events during active buffer load
to prevent competing clear+rewrite cycles (app.js)
- Move viewport+scrollback clear inside dimension-change guard so resize
without actual SIGWINCH doesn't blank the terminal (terminal-ui.js)
- Sync _lastResizeDims on explicit resize to prevent redundant clears
CJK input rewrite (input-cjk.js):
- Use InputEvent.inputType to distinguish insertText (final) from
insertCompositionText (tentative) — fixes Chinese punctuation and
English text being swallowed during Android IME composition
- Remove isComposing guard on Enter so it always sends
- Phantom character (U+200B) keeps textarea non-empty so Android
long-press backspace generates continuous deleteContentBackward
events at the keyboard's native repeat rate
CJK input settings:
- Add "CJK Input" toggle in Settings > Input (index.html, settings-ui.js)
- Store as device-specific setting (cjkInputEnabled), not synced to server
- Replace INPUT_CJK_FORM env var dependency with user-controlled setting
(env var still works as server override)
Mobile layout:
- Fix welcome screen overflow on phones by constraining .welcome-content
to calc(100vw - 1.5rem) (mobile.css)
- Move xterm helper textarea on-screen for touch devices to fix iOS
keyboard input (styles.css)
- Focus terminal synchronously in user-gesture context for iOS Safari
keyboard activation (session-ui.js, app.js)
- Refocus terminal on tap (not scroll) in touch handler (terminal-ui.js)
Two fixes for the tab-switching corruption bug:
1. _finishBufferLoad() now discards queued SSE events instead of flushing
them. The loaded API buffer is the source of truth — queued events
overlap with it, and flushing them writes duplicate Ink cursor-up
redraws that corrupt the terminal display (garbled text, wrong cursor
positions).
2. Skip stale cache write for busy sessions. When a session is actively
working, the cache is always outdated — writing it first and then
rewriting with the fresh API buffer caused a jarring double-render
flash. Now busy sessions get a single clean clear+write transition.

chunkedTerminalWrite used requestAnimationFrame to write buffer chunks across
frames but had no cancellation. When switching tabs, old session's remaining
chunks continued writing stale data into the new session's terminal, causing
visual artifacts and garbled content.
- Add _chunkedWriteGen generation counter to abort in-flight chunked writes
- Bump gen early in selectSession() and SSE reconnect to immediately cancel
- Guard finish() so aborted writes don't flush SSE queue for wrong session
- Add fitAddon.fit() before buffer writes to sync terminal dimensions
- Add fitAddon.fit() in sendResize() to ensure local/server dim parity

xterm.js DOM renderer doesn't populate .xterm-viewport's scroll area (the div
is empty, scrollHeight === clientHeight), so native CSS scrolling via
touch-action:pan-y and overflow-y:scroll had nothing to scroll. Desktop worked
only because the wheel handler called terminal.scrollLines() directly.
- Replace split mobile/desktop touch handlers with unified JS-driven handler
that converts touch deltas to terminal.scrollLines() calls (with pixel
accumulation for slow swipes and momentum scrolling)
- Change touch-action from pan-y to none on terminal elements so browser
doesn't fight the JS handler
- Remove now-unnecessary xterm-viewport position/overflow/z-index overrides
and iOS -webkit-overflow-scrolling rules
- Fix _shrinkPaddingToFit() arithmetic (was adding gap instead of subtracting)
- Minor: add route-helpers.ts to CLAUDE.md, fix sse-events.ts comment count

Split the monolithic app.js (~12.5K lines) into 6 focused mixin modules
that extend CodemanApp.prototype via Object.assign:
- terminal-ui.js — terminal setup, rendering pipeline, controls
- respawn-ui.js — respawn banner, countdown, presets, run summary
- ralph-panel.js — Ralph state panel, fix_plan, plan versioning
- settings-ui.js — app settings, visibility, web push, tunnel/QR, help
- panels-ui.js — subagent panel, teams, insights, file browser, log viewer
- session-ui.js — quick start, session options, case settings
Fix deferred script init ordering: wrap CodemanApp instantiation in
DOMContentLoaded so all defer'd mixin modules execute their
Object.assign before the constructor runs. Without this, init() calls
methods like applyHeaderVisibilitySettings() that don't exist yet.
Guard missing cleanupWizardDragging() call in subagent-windows.js.
Update build.mjs to minify/hash all new modules. Update CLAUDE.md
with new frontend architecture and load order.
