New SSE event orchestrator:planProgress streams phase/detail updates
from the planner to the frontend in real-time. The panel now shows
a scrollable log of planning steps instead of just "Generating plan..."

1. Post-phase verify timer leak — setTimeout for verifyCurrentPhase was
never stored, so pause() couldn't cancel it. Timer now tracked in
postPhaseTimer field and cleared in clearPhasePoll().
2. Event forwarding flag survives loop replacement — boolean
eventForwardingAttached stayed true when a new loop was created,
so the new loop never got SSE forwarding. Now tracks the loop
instance reference instead of a boolean.
3. Replan stuck when no sessions — replanPhase() returned without
setting up task handlers or polling when no idle sessions were
available. Now starts polling so the queued task gets picked up
when a session becomes idle.

Covers full lifecycle: start → plan → approve → execute → verify → complete.
Tests state transitions, event emissions, persistence/recovery, pause/resume,
skip/retry, team phase execution, error handling, and edge cases.
Also fixes bugs found during review:
- Route context snapshot: use getter for orchestratorLoop (was null forever)
- Event listener stacking: guard setupEventForwarding with boolean flag
- Replan completion: create tracked TaskQueue task instead of raw sendInput
- Pause cleanup: call cleanupTaskHandlers() on pause
- Phase timeout: add phaseTimeoutTimer enforcement

Adds a new autonomous loop that accepts high-level goals, generates
phased execution plans via AI, and executes them step-by-step with
verification gates between phases.
Core components:
- OrchestratorLoop: state machine (idle→planning→approval→executing→verifying→completed)
- OrchestratorPlanner: plan generation via PlanOrchestrator, Kahn's algorithm phase grouping
- OrchestratorVerifier: phase verification (strict/moderate/lenient modes)
- Prompt templates for phase execution, team delegation, verification, replanning
API (10 endpoints):
- POST start/approve/reject/pause/resume/stop
- GET status/plan
- POST phase/:id/skip, phase/:id/retry
Frontend: orchestrator-panel.js with SSE-driven state, phase progress, task tracking
Tests: 22 tests (18 route + 4 unit), all passing. Typecheck/lint/format clean.

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

iOS Safari scrolls the document to bring xterm's hidden textarea into
view when the user types, pushing the entire UI off-screen. Fix with:
- CSS position:fixed on .app when keyboard is visible
- window.scroll listener to reset scroll position as safety net
- scroll reset in onKeyboardShow before and after fit/resize

During long thinking phases, Ink's TUI rewrites the spinner/status bar
thousands of times via absolute cursor positioning (VPA/CUP). These
500KB+ of redraw frames pushed real content out of the 128KB tail
window, making the terminal appear empty when switching tabs.

- resolveCasePath now checks linked cases first (matching original behavior
of /api/cases/:name and /api/cases/:name/fix-plan handlers)
- readLinkedCases only warns on real I/O errors, not JSON parse errors
(SyntaxError has no .code property, so check for .code existence first)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Extract readLinkedCases() helper and resolveCasePath() to eliminate 6x duplicated
linked-cases.json path construction and 5x duplicated file read/parse logic
- Replace O(n) .some() duplicate check with O(1) Set.has() in case listing
- Un-export isError() in types/api.ts (only used internally by getErrorMessage)
- Standardize reply.status() → reply.code() in system-routes (Fastify canonical API)
- Update CLAUDE.md: accurate frontend module listing, SSE event count (~106)

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.

- Enable NODE_COMPILE_CACHE in systemd service and npm start for 10-20% faster cold starts
- Lazy-load xterm-addon-webgl.min.js (244KB) only on desktop — mobile never downloads it
- Add <link rel="preload"> hints for critical scripts (xterm, constants, app) in <head>
- Replace per-session tmux subprocess calls with single batch `list-panes -a` call
(N*2+1+M execSync calls → 1 for reconcileSessions)
- Fix CLAUDE.md frontend module count (10 → 11)

- Close WebSocket when session exits (exit event listener) to prevent
orphaned listeners and stale writes to dead PTY
- Add readyState guard in onTerminal to stop buffering after socket closes
- Simplify heartbeat: remove redundant alive flag, use pongTimeout only
- Add exponential backoff reconnection on unexpected WS close (skip for
server rejections 4004/4008/4009)
- Clear CJK textarea on session switch to prevent wrong-session input
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
WebSocket route: add socket error handler to prevent process crashes, enforce
per-session connection limit (max 5), track/decrement counts on close.
CJK input: add destroy() method with proper listener cleanup, guard against
double-init, add maxlength/aria-label to textarea, use language-neutral
placeholder, explicitly clear cjkActive on hide.
install.sh: fix update() to use $BRANCH and $REPO_URL instead of hardcoded
origin/master — fork users were silently switched back to master on update.
README: fix broken markdown table (paragraph concatenated into last cell),
add CODEMAN_NODE_VERSION to env var table.
Tests: add 8 new test cases for batch coalescing, flush threshold, unknown
message types, connection limit, heartbeat, readyState guards. Import
MAX_INPUT_LENGTH from config, add connectWs timeout, replace setTimeout
with vi.waitFor in cleanup test.

Detect stale connections that TCP keepalive won't catch for minutes,
especially through tunnels and proxies. Pings every 30s with a 10s
pong timeout — if the client doesn't respond, the socket is terminated
and all timers cleaned up.

The HTTP resize route validates via ResizeSchema (cols: 1-500, rows:
1-200, integers only). The WS handler only checked typeof === 'number',
allowing floats, negatives, and extreme values through to ptyProcess.

Add a dedicated textarea below the terminal for CJK (Korean/Japanese/Chinese)
IME input. xterm.js intercepts IME composition events, preventing composed
characters from displaying correctly. This textarea bypasses xterm entirely
by using native browser IME handling — text accumulates until Enter, then
sends to PTY in one shot.
- Always-visible textarea below terminal (inside .terminal-wrap flex column)
- focus/blur sets window.cjkActive flag to block xterm onData
- Enter sends textarea.value + \r to PTY, Escape clears
- Arrow keys, Ctrl+C/D/L/Z, Tab, Backspace pass through to PTY when empty
- attachCustomKeyEventHandler suppresses xterm key handling during composition
- INPUT_CJK_FORM=ON|OFF env var toggle (default: off, passed via SSE init)

Replace per-keystroke HTTP POST + SSE terminal output with a single
bidirectional WebSocket connection for dramatically lower input latency.
The existing SSE+POST paths remain fully functional as fallback.
Server-side: ws-routes.ts provides /ws/sessions/:id/terminal with 8ms
micro-batching and 16KB flush threshold. Each batch is wrapped in
DEC 2026 synchronized update markers so xterm.js renders atomically —
Ink's DA capability negotiation fails through the PTY→server→WS proxy
chain, so without server-injected markers, cursor-up redraws flicker.
Frontend: _connectWs/_disconnectWs manage per-session WS lifecycle.
Input and resize use WS fast path with HTTP POST fallback. SSE terminal
events are suppressed when WS is active to prevent double rendering.

Change showSubagents default from true to false so the subagent
panel doesn't auto-show on page load. Users can still enable it

Use resumeSessionId for Claude conversation ID when resuming sessions,
increase default font size to 14, extract shared history fetch logic,
and remove unused DEC 2026 sync constants/functions (xterm.js 6.0 handles natively).

- Scope toolbar bottom-offset to phone breakpoint only (position:fixed);
prevents double-correction on iPad where toolbar is position:relative
- Extract keyboard accessory bar styles to top-level mobile.css so
/init, /clear, /compact buttons render correctly on iPad
- Use desktop-style toolbar sizing on tablet (430-768px): smaller font,
no forced min-height, proper gap between buttons
- Show voice/mic button on tablet (was hidden at <1023px with no
mobile replacement above 430px)
- Bump CSS cache-bust version to 0.1633

- Default terminal font 14px → 12px, min 10px → 8px
- Save tab metadata to localStorage on every render
- Restore ended sessions as dimmed tabs after page refresh
- Ended tabs show "Session ended" message on click
- Filter empty sessions from history API (check for conversation content)
- Add --resume fallback to new session if resume fails (prevents dead panes)
- Pass resumeSessionId through respawnPane for dead pane recovery
- Persist respawn presets and runMode to server settings (cross-device sync)
- Fix mobile touch handling for Recent Sessions dropdown (DOM API + touch CSS)
selectSession() was always calling /interactive for restored idle
sessions regardless of mode. Shell sessions now correctly call /shell.
Also add loadHistorySessions and resumeHistorySession to frontend.
Add GET /api/history/sessions endpoint that scans Claude conversation
files for resume. Add welcome overlay UI with clickable history items.
Path decoding validates existence via fs.access with HOME fallback.
Add resumeSessionId field throughout the session creation pipeline,
allowing sessions to resume previous Claude conversations via --resume
flag instead of --session-id.
On iPad Safari with the tab bar visible, `100vh` extends behind the
browser chrome, pushing the fixed-position toolbar out of view.
- Add `viewport-fit=cover` to viewport meta tag
- Use `100dvh` with `100vh` fallback for body/.app height
- Set `--app-height` CSS variable from `visualViewport.height` via JS
- Offset fixed toolbar on iOS Safari using the layout/visual viewport delta
Green pulsing dot in the desktop header shows when Cloudflare tunnel is active.
Clicking opens a dropdown panel with tunnel URL, remote client count, auth
sessions, and start/stop/QR/revoke controls. Detects tunnel clients via
Cf-Connecting-Ip header to exclude local connections from the count.

Two hardcoded `256 * 1024` tail sizes in app.js bypassed the
TERMINAL_TAIL_SIZE constant (128KB), causing stale cached browsers
to fetch 256KB buffers even after the constant was reduced to prevent
WebGL GPU stalls. Also adds a self-recovery timer that reloads the
terminal buffer after client-side data drops, preventing permanent
display corruption.

- Add SSE padding to backpressure drain write for tunnel clients
- Remove dead SessionTerminal from broadcast padding check
- Trim whitespace in SSE session filter query params
- Remove unused _bufferLazyTerminalData scaffolding code
- Skip WebGL on tablets too, not just phones (canvas fallback)

1. Session-scoped SSE subscriptions: server filters events by session ID,
clients can subscribe via ?sessions=id1,id2 (backwards-compatible)
2. Lazy xterm.js for subagent windows: terminals created on restore,
disposed on minimize — saves ~3.75MB DOM at 50 agents
3. Targeted badge updates: badge count changes update the <span> directly
instead of rebuilding the entire session tab sidebar (O(1) vs O(n))
4. Conditional SSE padding: 8KB Cloudflare padding only on session:terminal
and session:needsRefresh, not every event (~70% bandwidth reduction)
5. Canvas renderer on mobile: skip WebGL addon on mobile devices to reduce
GPU pressure and prevent context loss on weaker mobile GPUs
All 5 implemented in parallel via isolated git worktrees, merged conflict-free.

Add three layers of protection against oversized terminal.write() calls
that freeze Chrome's main thread:
1. SSE entry cap: _onSessionTerminal drops data when total queued bytes
(pendingWrites + flickerFilterBuffer) exceeds 128KB. Server sends
session:needsRefresh to recover dropped content.
2. Flush cap: flushPendingWrites splits at DEC 2026 sync segment
boundaries with 64KB per-frame budget. Excess segments deferred to
next requestAnimationFrame. Segment-level splitting preserves Ink
redraw atomicity (no flicker).
3. Reduced tail size: initial buffer fetch reduced to 128KB (from 256KB)
to limit data volume during tab switch.
Re-enable WebGL renderer — root cause was unbounded terminal.write()
volume, not the GPU renderer itself.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Root cause was NOT WebGL — breadcrumbs showed 141KB single-frame
terminal.write() calls freezing Chrome for 2+ minutes even with the
canvas renderer. During heavy Ink output, multiple SSE terminal events
accumulate between animation frames and flush all at once.
Fix: split flushPendingWrites at DEC 2026 sync segment boundaries with
a 48KB per-frame budget. Each segment is a complete Ink redraw, so
splitting between them preserves atomicity (no flicker). Excess
segments are deferred to the next requestAnimationFrame.
Also re-enable WebGL since it was not the cause — the flush cap
protects both renderers equally.
