Subject: [PATCH 01/57] Add CCBOT_BROWSE_ROOT config for directory browser
 start path

New env var sets a fixed starting directory for the directory browser,
falling back to Path.cwd() if not set (preserving current behavior).

Subject: [PATCH 02/57] Fix inconsistent Path.cwd() fallbacks in directory
 browser callbacks

Four callback handlers (CB_DIR_SELECT, CB_DIR_UP, CB_DIR_PAGE,
CB_DIR_CONFIRM) and build_directory_browser's invalid-path fallback
used raw Path.cwd() instead of config.browse_root. This meant users
could escape the configured browse root if user_data was lost or the
path became invalid during navigation.

Subject: [PATCH 03/57] Fix misc bugs: asyncio deprecation, double stat,
 missing /kill handler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- session.py: Replace deprecated asyncio.get_event_loop() with
  asyncio.get_running_loop() (Python 3.12+ compat)
- session.py: Remove redundant pass statements
- session_monitor.py: Consolidate double stat() call into one
- screenshot.py: Add explicit parens in _font_tier() for clarity
- bot.py: Add /kill command handler — kills tmux window, unbinds
  thread, cleans up state, and best-effort deletes the topic.
  Previously the /kill bot command was registered in the menu but
  had no handler, falling through to forward_command_handler.

Subject: [PATCH 04/57] Fix duplicate Telegram messages for interactive UI
 prompts

Add timestamp-based deduplication in handle_interactive_ui() to prevent
both JSONL monitor and status poller from sending new interactive messages
in the same short window. The check-and-set has no await between them,
making it atomic in the asyncio event loop.

Also add a defensive check in status_polling.py to skip calling
handle_interactive_ui() when an interactive message is already tracked
for the user/thread (e.g. sent by the JSONL monitor path).

could allow concurrent unbind_thread() calls to mutate the dict mid-iteration,
causing RuntimeError: dictionary changed size during iteration.

Fix: rename to all_thread_bindings() returning a materialized list snapshot.
The list comprehension captures all (user_id, thread_id, window_id) tuples
eagerly, so no live dict reference escapes across await points.

Changes:
- session.py: iter_thread_bindings -> all_thread_bindings, returns list
- bot.py, status_polling.py: update all 4 call sites
- Remove unused Iterator import from collections.abc
- Add tests: snapshot independence, returns list type, empty bindings

Subject: [PATCH 06/57] Replace blocking queue.join() with enqueue_callable for
 interactive UI

queue.join() in handle_new_message blocked the entire monitor loop while
waiting for one user's queue to drain. If Telegram was rate-limiting, this
could stall all sessions for 30+ seconds.

Fix: use enqueue_callable() to push interactive UI handling as a callable
task into the queue. The worker executes it in FIFO order after all pending
content messages, guaranteeing correct ordering without blocking.

Also fixes:
- Callable tasks silently dropped during flood control (the guard checked
  task_type != "content" which matched "callable" too; changed to explicit
  check for "status_update"/"status_clear" only)
- Updated stale docstring in _merge_content_tasks referencing queue.join()

 send_chat_action

unpin_all_forum_topic_messages was used every 60s to detect deleted topics,
but it destructively removed all user-pinned messages as a side effect.

Replace with send_chat_action(ChatAction.TYPING) which is ephemeral
(5s typing indicator) and raises the same BadRequest("Topic_id_invalid")
for deleted topics. All existing error handling works unchanged.

Subject: [PATCH 08/57] Add RetryAfter retry loop with callable factory fix

- Add MAX_TASK_RETRIES=3 retry loop for short RetryAfter (sleep and retry)
- Re-queue tasks on long RetryAfter (>10s) with MAX_REQUEUE_COUNT=5 cap
- Convert callable_fn from Coroutine to Callable factory (coroutines are
  single-use; retry requires a fresh coroutine each attempt)
- Catch RetryAfter from _check_and_send_status to prevent cosmetic status
  updates from triggering content message re-sends
- Fix test isolation: clear _last_interactive_send in test fixtures

Subject: [PATCH 09/57] Remove mtime cache, use size-only fast path for file
 change detection

The _file_mtimes dict used mtime+size to skip unchanged JSONL files, but
this introduced edge cases (sub-second writes, clock skew, file replacement).
For append-only JSONL files, comparing file size against last_byte_offset is
sufficient and eliminates all mtime-related issues.

Subject: [PATCH 10/57] Move save_if_dirty after message delivery for
 at-least-once semantics

Previously byte offsets were persisted to disk BEFORE delivering messages
to Telegram. If the bot crashed after save but before delivery, messages
were silently lost. Now offsets are saved AFTER the delivery loop,
guaranteeing at-least-once delivery: a crash before save means messages
are re-read and re-delivered on restart (safe duplicate) rather than
permanently lost.

Dead sessions were cleaned from persistent state but never from the
in-memory _pending_tools dict, causing a slow memory leak over time.
Add pop() calls in both cleanup paths (startup + runtime).

Previously _pending_thread_text was cleared from user_data BEFORE
attempting to send it to the tmux window. If send_to_window() failed,
the message was lost and the user had to retype it. Now the pending
text is only cleared after a successful send.

Subject: [PATCH 14/57] Fix overly broad exception handling in
 handle_interactive_ui

The except Exception handler was catching RetryAfter (Telegram 429
rate limiting) and BadRequest("message is not modified"), preventing
proper rate limit propagation and causing unnecessary duplicate
message sends.

Changes:
- Re-raise RetryAfter in both edit and send paths so the queue
  worker retry loop can handle rate limiting correctly
- Treat BadRequest "is not modified" as success (content identical)
- For other BadRequest errors (message deleted, too old), delete
  orphan message before falling through to send new
- Log exception details in catch-all handler for debugging

Subject: [PATCH 15/57] Add generation counter to prevent stale interactive UI
 callables

When JSONL monitoring enqueues _send_interactive_ui, the callable may
execute after the interactive UI has been dismissed. This caused stale
callables to potentially send duplicate interactive messages.

Fix: introduce a monotonically incrementing generation counter per
(user_id, thread_id) key. Every state transition (set_interactive_mode,
clear_interactive_mode, clear_interactive_msg) increments the counter.
The JSONL monitor captures the generation at enqueue time and passes it
to handle_interactive_ui via expected_generation parameter. If the
generation has changed by execution time, the function bails out.

The status poller is unaffected (passes None, skipping the guard).

The return value was already handled correctly (proceed regardless),

on timeout the monitor's 2s poll cycle picks up the entry, and thread
binding, pending text, and topic rename work without session_map.

Subject: [PATCH 18/57] Fix screenshot refresh showing broken preview by
 switching to photo media

Telegram clients fail to re-render document thumbnails when editing
document-type media in place via editMessageMedia, causing a "white
circle with X" on screenshot refresh. Switch from reply_document +
InputMediaDocument to reply_photo + InputMediaPhoto, which Telegram
clients handle reliably for inline image edits.

Also adds debug logging for the key-press screenshot edit path.

Content-Transfer-Encoding: 8bit

Check pane_current_command before sending keys to tmux windows.
If the pane is running a shell (bash, zsh, etc.), Claude Code has
exited and user text must not be forwarded — it would execute as
shell commands.

Guards added to: send_to_window (safety net), text_handler (with
auto-unbind), esc_command, usage_command, and screenshot key-press
callback.

Subject: [PATCH 20/57] Auto-resume Claude Code when pane drops to shell
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When send_to_window detects the pane is running a shell, it now
captures the pane content and looks for:
  - "Stopped ... claude" → sends "fg" (suspended process)
  - "claude --resume <id>" → sends the resume command

Waits up to 3s (fg) or 15s (--resume) for Claude Code to take
over the terminal, then sends the user's original text.

If no resume command is found, the text_handler unbinds the topic
and tells the user to start a new session.

Subject: [PATCH 21/57] Optimize tmux performance with list_windows cache and
 unified capture_pane

Reduces tmux subprocess calls from ~120/s to ~21/s with 20 windows by:
- Adding 1-second TTL cache to list_windows() (all callers in the same
  poll cycle share one tmux enumeration instead of N)
- Unifying capture_pane() to always use direct `tmux capture-pane`
  subprocess (plain text mode previously used libtmux which generated
  3-4 tmux round-trips per call)
- Invalidating cache on mutations (create/kill/rename)

+# CCBot Workshop Setup Guide
+
+Complete setup from a fresh Windows machine to running CCBot with Claude Code sessions accessible via Telegram.
+
+---
+
+## Prerequisites
+
+Before you begin, you'll need:
+
+- Windows 10 (version 2004+) or Windows 11
+- A Telegram account
+- A Claude Code subscription (Claude Pro/Team/Enterprise)
+- Your project repositories cloned into `C:\GitHub\`
+
+---
+
+## Part 1: Install WSL and Ubuntu
+
+Open **PowerShell as Administrator** and run:
+
+```powershell
+wsl --install
+```
+
+This installs WSL 2 with Ubuntu. Restart your computer when prompted.
+
+After restart, Ubuntu will open automatically and ask you to create a username and password. Remember these — you'll need the password for `sudo` commands.
+
+Once you're at the Ubuntu prompt, update everything:
+
+```bash
+sudo apt update && sudo apt upgrade -y
+```
+
+---
+
+## Part 2: Install Core Tools
+
+### Node.js (required for Claude Code)
+
+```bash
+curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
+sudo apt install -y nodejs
+```
+
+Verify:
+
+```bash
+node --version
+npm --version
+```
+
+### Claude Code
+
+```bash
+npm install -g @anthropic-ai/claude-code
+```
+
+Add npm global bin to your PATH if not already there:
+
+```bash
+echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
+source ~/.bashrc
+```
+
+Verify Claude Code works:
+
+```bash
+claude --version
+```
+
+### tmux
+
+```bash
+sudo apt install -y tmux
+```
+
+### uv (Python package manager)
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+Then:
+
+```bash
+source ~/.bashrc
+```
+
+---
+
+## Part 3: Create a Telegram Bot
+
+1. Open Telegram and search for **@BotFather**
+2. Send `/newbot`
+3. Follow the prompts to name your bot
+4. BotFather gives you a **bot token** — save it (looks like `1234567890:ABCdefGHIjklMNOpqrsTUVwxyz`)
+
+### Get your Telegram user ID
+
+1. Search for **@userinfobot** in Telegram
+2. Start a chat with it
+3. It replies with your numeric user ID — save it
+
+### Create a Telegram group
+
+1. Create a new group in Telegram
+2. Name it something like "Workshop Sessions"
+3. Add your bot to the group
+4. Go to group settings → **Topics** → Enable topics (use list format)
+5. Make the bot an **admin** of the group
+
+---
+
+## Part 4: Install CCBot Workshop
+
+```bash
+uv tool install git+https://github.com/JanusMarko/ccbot-workshop.git
+```
+
+Verify it installed:
+
+```bash
+which ccbot
+```
+
+If it's not found, add the path:
+
+```bash
+export PATH="$HOME/.local/bin:$PATH"
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
+```
+
+### Configure CCBot
+
+Create the config directory and environment file:
+
+```bash
+mkdir -p ~/.ccbot
+nano ~/.ccbot/.env
+```
+
+Paste the following, replacing the placeholder values with your actual token and user ID:
+
+```
+TELEGRAM_BOT_TOKEN=your_bot_token_here
+ALLOWED_USERS=your_telegram_user_id_here
+TMUX_SESSION_NAME=ccbot
+CLAUDE_COMMAND=claude --dangerously-skip-permissions
+CCBOT_BROWSE_ROOT=/mnt/c/GitHub
+```
+
+Save with `Ctrl+O`, exit with `Ctrl+X`.
+
+The `CCBOT_BROWSE_ROOT` setting ensures the directory browser always starts from your `C:\GitHub\` folder when creating new sessions.
+
+### Install the Claude Code hook
+
+This lets CCBot track which Claude session runs in which tmux window:
+
+```bash
+ccbot hook --install
+```
+
+Or manually add to `~/.claude/settings.json`:
+
+```json
+{
+  "hooks": {
+    "SessionStart": [
+      {
+        "hooks": [{ "type": "command", "command": "ccbot hook", "timeout": 5 }]
+      }
+    ]
+  }
+}
+```
+
+---
+
+## Part 5: Starting CCBot
+
+### First time startup
+
+```bash
+tmux new -s ccbot
+```
+
+Inside the tmux session:
+
+```bash
+ccbot
+```
+
+You should see log output confirming the bot started, including your allowed users and Claude projects path.
+
+### Detach from tmux
+
+Press `Ctrl+b`, release, then press `d`. CCBot keeps running in the background. You can close the terminal — it stays alive.
+
+### Start a session from Telegram
+
+1. Open your Telegram group
+2. Create a new topic (name it after your project, e.g. "PAIOS")
+3. Send a message in the topic
+4. CCBot shows a directory browser starting from `C:\GitHub\` — tap your project folder
+5. Tap **Select** to confirm
+6. A new tmux window is created with Claude Code running in that directory
+7. Your message is forwarded to Claude Code
+
+### View sessions in the terminal
+
+```bash
+tmux attach -t ccbot
+```
+
+Switch between windows using `Ctrl+b` then the window number (shown in the bottom bar). For example:
+
+- `Ctrl+b` then `1` → ccbot process (don't close this)
+- `Ctrl+b` then `2` → first Claude Code session
+- `Ctrl+b` then `3` → second Claude Code session
+
+Detach again with `Ctrl+b` then `d`.
+
+---
+
+## Part 6: Daily Usage
+
+### Starting CCBot after a reboot
+
+```bash
+tmux new -s ccbot || tmux attach -t ccbot
+ccbot
+```
+
+Then `Ctrl+b` then `d` to detach.
+
+### Useful Telegram commands
+
+Send these in a topic:
+
+- `/screenshot` — see what the terminal looks like right now
+- `/history` — browse conversation history
+- `/esc` — send Escape key (toggles plan mode, same as Shift+Tab)
+- `/cost` — check token usage
+- `/kill` — kill the session and delete the topic
+
+### Ending a session
+
+Close or delete the topic in Telegram. The tmux window is automatically killed.
+
+### Multiple projects
+
+Create a new topic for each project. CCBot's design is **1 topic = 1 window = 1 session**. Each topic can run a separate Claude Code session in a different project directory.
+
+### Switching between phone and desktop
+
+From your phone, just use Telegram — all interaction goes through topics.
+
+To switch to your desktop terminal:
+
+```bash
+tmux attach -t ccbot
+```
+
+Navigate to the right window with `Ctrl+b` then the window number. You're in the same session with full scrollback.
+
+---
+
+## Part 7: Uninstall and Reinstall
+
+Use this after pushing updates to your fork.
+
+### Stop CCBot
+
+```bash
+tmux attach -t ccbot
+```
+
+Press `Ctrl+C` to stop ccbot. Stay in the tmux session.
+
+### Uninstall the current version
+
+```bash
+uv tool uninstall ccbot
+```
+
+### Install the updated version
+
+```bash
+uv tool install git+https://github.com/JanusMarko/ccbot-workshop.git
+```
+
+If you're getting a cached version and not seeing your changes, force a fresh install:
+
+```bash
+uv tool install --force git+https://github.com/JanusMarko/ccbot-workshop.git
+```
+
+### Verify and restart
+
+```bash
+which ccbot
+ccbot
+```
+
+Then `Ctrl+b` then `d` to detach.
+
+Your `~/.ccbot/.env` configuration and `~/.ccbot/state.json` session state are preserved across reinstalls — you don't need to reconfigure anything.

Subject: [PATCH 23/57] Fix duplicate interactive UI messages for numbered
 answers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an assistant message contains both text blocks and an interactive
tool_use (ExitPlanMode/AskUserQuestion), the text entries were processed
first in handle_new_message, clearing the interactive UI state set by the
status poller. This caused the JSONL callable to send a second interactive
message instead of editing the existing one.

Fix: pre-scan assistant messages for interactive tools and suppress text
block emission when present — the terminal capture already includes that
preamble text.

Subject: [PATCH 24/57] Add OOM detection and memory monitoring for tmux
 sessions

When a tmux window dies, the status poller now checks dmesg for OOM
kills matching the window's process tree and notifies the user in the
Telegram topic with the reason (OOM vs normal exit). Optionally monitors
RSS memory of Claude processes and warns when usage exceeds threshold.

- Add process_info.py: /proc-based process tree, RSS reading, dmesg OOM parsing
- Add TmuxManager.get_pane_pid() for correlating windows to processes
- Track pane PIDs in status poller for post-mortem OOM detection
- Send session-end notification to user topic on window death
- Add opt-in memory monitoring (CCBOT_MEMORY_MONITOR=true)
- Config: CCBOT_MEMORY_WARNING_MB (default 2048), CCBOT_MEMORY_CHECK_INTERVAL (30s)

From 2d431bb51afa6a7b623c5f147a260e28d8b125c5 Mon Sep 17 00:00:00 2001
From: Claude <noreply@anthropic.com>
Date: Sun, 8 Mar 2026 01:19:36 +0000
Subject: [PATCH 25/57] Add session death context to crash notifications
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a tmux window dies, the notification now includes what Claude was
doing at the time — extracted from the tail of the session JSONL file.
Shows pending/running tools, last completed tool, and last assistant
message (truncated to 200 chars).

Example notification:
  ⚠️ Session killed by OOM killer (process: node, RSS: 14500MB): refinery
  Last activity:
  • Running: Bash(`npm run test:e2e`)
  • Last message: "All 4 test agents running in parallel..."

Subject: [PATCH 26/57] Trying to deal with OOM issues still
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

  Summary of Changes

  src/ccbot/process_info.py

  - Added get_mem_available_mb() — reads /proc/meminfo for MemAvailable, returns MB as float (None on non-Linux)

  src/ccbot/config.py

  - Memory monitoring now on by default (opt-out with CCBOT_MEMORY_MONITOR=false)
  - Lowered memory_check_interval from 30s → 10s
  - Added 3 new threshold configs:
    - CCBOT_MEM_AVAIL_WARN_MB (1024) — triggers notification
    - CCBOT_MEM_AVAIL_INTERRUPT_MB (512) — sends Escape to heaviest session
    - CCBOT_MEM_AVAIL_KILL_MB (256) — kills heaviest session

  src/ccbot/handlers/status_polling.py

  - Added _find_highest_rss_window() — finds the window consuming the most memory
  - Added _check_system_memory() — escalating system memory response:
    - Level 1 (warn): Notifies all topics that system memory is low
    - Level 2 (interrupt): Sends Escape to the heaviest window
    - Level 3 (kill): Kills the heaviest window, cleans up bindings
  - Safety mechanisms:
    - One level per check cycle (can't jump from OK to kill)
    - Cooldowns: 2 cycles (~20s) after interrupt before kill, 3 cycles (~30s) between kills
    - Hysteresis: resets to normal when memory recovers above warn × 1.5
    - Downgrade: level drops when pressure partially relieves
    - No-target fallback: resets state if there are no windows to act on
  - Updated module docstring

  Tests

  - tests/ccbot/test_process_info.py — Added TestGetMemAvailableMb (3 tests)
  - tests/ccbot/handlers/test_system_memory.py — New file with 11 tests covering: normal operation, warn,
  one-level-per-cycle, interrupt escalation, cooldowns, kill + cleanup, hysteresis, partial pressure relief downgrade,
  disabled monitor, non-Linux fallback, highest-RSS finde

Subject: [PATCH 27/57] Add Telegram document upload and message type emojis
 (#9)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add document upload handler for text/markdown files

Save uploaded text-based files (Markdown, code, config, etc.) to
{session_cwd}/docs/inbox/ and forward the file path to Claude Code.
Follows the same pattern as the existing photo_handler.

https://claude.ai/code/session_01Db4zZKSaAkJrgHGzeLjRsz

* Support PDF and Word document uploads in document handler

- PDFs: saved directly to docs/inbox/ (Claude Code reads them natively)
- Word docs (.docx/.doc): converted to Markdown via python-docx, saved as .md
- Added python-docx dependency
- Updated MIME type and extension allowlists

https://claude.ai/code/session_01Db4zZKSaAkJrgHGzeLjRsz

* Put file notification before user caption in document handler

Claude Code needs to know the file exists before processing the user's
instruction. Reorder so the file path/read hint comes first, followed
by the user's caption text.

https://claude.ai/code/session_01Db4zZKSaAkJrgHGzeLjRsz

* Add speech balloon emoji prefix to assistant text messages

Prefixes human-readable assistant messages with 💬 so they're
visually distinct from tool_use/tool_result messages in Telegram.

https://claude.ai/code/session_01Db4zZKSaAkJrgHGzeLjRsz

* Use colorful square emojis for all message type prefixes

- 🟦 User messages
- 🟩 Assistant text
- 🟧 Tool use / tool result
- 🟪 Thinking

https://claude.ai/code/session_01Db4zZKSaAkJrgHGzeLjRsz

* Use colorful emojis for message type prefixes

- 💎 User messages
- 🔮 Assistant text
- 🛠️ Tool use / tool result
- 🧠 Thinking

Fixes ModuleNotFoundError on fresh install. The module is imported
directly in markdown_v2.py but was only a transitive dep.

Subject: [PATCH 30/57] Add ccweb: React web gateway to Claude Code (Phase 1
 backend)

New self-contained project in ccweb/ that replaces the Telegram interface
with a browser-based web frontend for Claude Code sessions via tmux.

Backend (Python/FastAPI):
- Forked 7 core modules from ccbot (tmux_manager, terminal_parser,
  session_monitor, transcript_parser, monitor_state, hook, utils)
  with imports adapted for ccweb (ccweb_dir, separate ~/.ccweb/ state)
- New config.py: web server settings, no Telegram dependencies
- New session.py: simplified client_bindings model (no thread_bindings)
- New server.py: FastAPI + WebSocket for real-time bidirectional comms
- New ws_protocol.py: typed message definitions (message, interactive_ui,
  decision_grid, status, sessions, health, error, replay)
- New ui_parser.py: parses raw terminal text into structured interactive
  UI data with fallback to raw text display
- New main.py: CLI with ccweb (serve), ccweb install (hook + commands),
  ccweb hook (SessionStart handler)
- Startup health checks: tmux running, hook installed, config valid
- Stale UI guard on interactive prompts (re-captures pane before acting)

Decision grid protocol: file-based detection (.ccweb/pending/*.json)
with AskUserQuestion blocking to prevent timing issues.

Docs:
- Full design plan (docs/architecture/design-plan.md)
- V2 roadmap (docs/architecture/v2-roadmap.md)

+"""JSONL transcript parser for Claude Code session files.
+
+Parses Claude Code session JSONL files and extracts structured messages.
+Handles: text, thinking, tool_use, tool_result, local_command, and user messages.
+Tool pairing: tool_use blocks in assistant messages are matched with
+tool_result blocks in subsequent user messages via tool_use_id.
+
+Forked from ccbot — removed Telegram expandable quote sentinels.
+Collapsible content is handled by the React frontend, not by text markers.

+# CCWeb: React Web Gateway to Claude Code
+
+## Context
+
+CCBot currently bridges Telegram Forum topics to Claude Code sessions via tmux. The user wants a **richer web-based interface** that replaces Telegram entirely, with:
+- A styled message stream (not raw terminal) with text input for sending messages/commands
+- Interactive components: when Claude asks questions (AskUserQuestion, permission prompts), render them as clickable HTML instead of terminal navigation
+- A **decision grid** system: a Claude Code skill outputs structured options, CCWeb renders them as an interactive HTML grid, user clicks selections, answers sent back to Claude Code
+- Session management (create, switch, kill) similar to Telegram topics
+
+The existing ccbot backend (tmux management, session monitoring, terminal parsing, JSONL parsing, hook system) is transport-agnostic and highly reusable. The Telegram-specific layer (bot.py, handlers/, markdown_v2.py, telegram_sender.py) gets replaced.
+
+## User Workflow
+
+**Current (ccbot + Telegram):**
+```
+WSL → tmux → run `ccbot` → interact via Telegram app
+```
+
+**New (ccweb + Browser):**
+```
+WSL → tmux → run `ccweb` → interact via browser at http://<tailscale-host>:8765
+```
+
+Everything else stays the same: Claude Code still runs in tmux windows, the SessionStart hook still writes session_map.json, the monitor still polls JSONL files. Only the UI layer changes.
+
+Both can coexist: run `ccbot` AND `ccweb` simultaneously, both connecting to the same tmux sessions.
+
+## Interactive UI in the Browser
+
+All interactive Claude Code UIs currently handled by ccbot's terminal-navigation keyboard will be rendered as proper HTML components:
+
+| Claude Code UI | Current (Telegram) | CCWeb (Browser) |
+|---|---|---|
+| ExitPlanMode | Arrow-key navigation | "Proceed" / "Edit Plan" buttons, plan rendered as markdown |
+| AskUserQuestion | Arrow-key checkboxes | Clickable option cards, click to select + Submit |
+| Permission Prompt | Arrow-key Yes/No | "Allow" / "Deny" buttons with action description |
+| Bash Approval | Arrow-key approve | "Run" / "Deny" with command in code block |
+| Settings/Model | Arrow-key menu | Dropdown or card selector |
+
+Detection uses the same `terminal_parser.py` from ccbot — `extract_interactive_content()` identifies the UI type and content, then the backend sends structured data to the frontend via WebSocket, and the frontend renders the appropriate component. When the user clicks, the frontend sends the corresponding key (Enter, Escape, Space, Tab, arrows) back to tmux.
+
+## Design Constraints
+
+- **Single user**: This is a single-user application. No multi-user auth, no per-user state separation. The one user who runs `ccweb` is the only user.
+- **Single browser session at a time**: While multiple tabs technically work (fan-out from SessionMonitor callback), interactive UI responses are not tab-locked — last click wins. This is acceptable for single-user.

+
+## Module Reuse Map
+
+### Forked Modules (NOT verbatim copies — all need adaptation)
+Every ccbot module imports `from .config import config` and `from .utils import ccbot_dir`. These are **forks**, not copies. Each needs:
+- Import paths updated (now under `ccweb.backend.core`)
+- `ccbot_dir()` → `ccweb_dir()` (returns `~/.ccweb/` or `$CCWEB_DIR`)
+- Config interface matched to the new ccweb config singleton
+
+| Source | Destination | Changes Required |
+|--------|------------|-----------------|
+| `src/ccbot/tmux_manager.py` | `ccweb/backend/core/tmux_manager.py` | Update config import. Uses `config.tmux_session_name`, `config.claude_command`, `config.tmux_main_window_name` — new config must expose same attrs. |
+| `src/ccbot/terminal_parser.py` | `ccweb/backend/core/terminal_parser.py` | Zero config deps — this one IS a true copy. Pure regex, no imports from config/utils. |
+| `src/ccbot/session_monitor.py` | `ccweb/backend/core/session_monitor.py` | Update config import. Uses `config.claude_projects_path`, `config.monitor_poll_interval`, `config.session_map_file`, `config.show_user_messages`. |
+| `src/ccbot/monitor_state.py` | `ccweb/backend/core/monitor_state.py` | Update utils import (`atomic_write_json`). Otherwise clean. |
+| `src/ccbot/hook.py` | `ccweb/backend/core/hook.py` | Update to write to `~/.ccweb/session_map.json` (via `ccweb_dir()`). Hook command becomes `ccweb hook` instead of `ccbot hook`. |
+| `src/ccbot/utils.py` | `ccweb/backend/core/utils.py` | Rename `ccbot_dir()` → `ccweb_dir()`, default `~/.ccweb/`, env var `CCWEB_DIR`. |
+| `src/ccbot/transcript_parser.py` | `ccweb/backend/core/transcript_parser.py` | Remove `EXPANDABLE_QUOTE_START/END` sentinels. Keep all JSONL parsing logic. |
+| `src/ccbot/config.py` | `ccweb/backend/config.py` | Full rewrite. Remove Telegram vars. Add web vars. Must expose same attribute names used by forked modules: `tmux_session_name`, `tmux_main_window_name`, `claude_command`, `claude_projects_path`, `monitor_poll_interval`, `state_file`, `session_map_file`, `monitor_state_file`, `show_user_messages`, `show_hidden_dirs`, `browse_root`, `memory_monitor_enabled`, etc. |
+| `src/ccbot/session.py` | `ccweb/backend/session.py` | Replace `thread_bindings` with `client_bindings` (client_id → window_id). Remove group_chat_ids. Keep window_states, user_window_offsets, load_session_map, resolve_stale_ids, send_to_window, get_recent_messages. |
+
+### Drop (Telegram-only, replaced by web equivalents)
+- `src/ccbot/bot.py` → replaced by `server.py`
+- `src/ccbot/handlers/` → replaced by WebSocket message handlers in `server.py`
+- `src/ccbot/markdown_v2.py` → React renders markdown natively
+- `src/ccbot/telegram_sender.py` → WebSocket sends (no 4096 char limit)
+- `src/ccbot/screenshot.py` → optional; styled view replaces primary use
+
+## WebSocket Protocol (`ws_protocol.py` / `protocol.ts`)
+
+Bidirectional JSON messages over WebSocket:
+
+### Server → Client
+```
+# New message from Claude (text, thinking, tool_use, tool_result)
+{"type": "message", "window_id": "@0", "role": "assistant", "content_type": "text",
+ "text": "...", "tool_use_id": null, "tool_name": null, "timestamp": "..."}
+
+# Interactive UI detected (AskUserQuestion, permission, etc.)
+{"type": "interactive_ui", "window_id": "@0", "ui_name": "AskUserQuestion",
+ "content": "...", "options": [...]}   # parsed from terminal capture
+
+# Decision grid (custom skill output)
+{"type": "decision_grid", "window_id": "@0", "grid": {...}}
+
+# Status update (spinner, working text)
+{"type": "status", "window_id": "@0", "text": "Reading files..."}
+
+# Session list update
+{"type": "sessions", "sessions": [{"window_id": "@0", "name": "project", "cwd": "/path"}]}
+```
+
+### Client → Server
+```
+# Send text to Claude (like typing in terminal/Telegram)
+{"type": "send_text", "window_id": "@0", "text": "Fix the bug in auth.py"}
+
+# Send key press (for interactive UI navigation)
+{"type": "send_key", "window_id": "@0", "key": "Enter"}
+
+# Submit decision grid selections (each item has selected option + optional notes)
+{"type": "submit_decisions", "window_id": "@0", "selections": [
+  {"topic": "Auth module refactor", "choice": "Update to bcrypt v4 API", "notes": ""},
+  {"topic": "Error handling", "choice": "Add retry with backoff", "notes": "Handle 429 specifically"},
+  {"topic": "Logging", "choice": null, "notes": "Let's discuss structured logging first"}
+]}
+
+# Session management
+{"type": "create_session", "work_dir": "/path/to/project", "name": "my-project"}
+{"type": "kill_session", "window_id": "@0"}
+{"type": "switch_session", "window_id": "@0"}
+
+# Request history
+{"type": "get_history", "window_id": "@0", "page": 0}
+```
+
+## Decision Grid Protocol
+
+For the user's custom skill that generates option grids:
+
+1. **Detection**: The skill writes a JSON file to `{session_cwd}/.ccweb/decisions/{id}.json`
+2. **Backend monitors** this directory (or the skill outputs a marker in JSONL text)
+3. **Grid JSON schema**:
+```json
+{
+  "id": "decision-001",
+  "title": "Code Review Decisions",
+  "items": [
+    {
+      "topic": "Auth module refactor",
+      "description": "The auth module uses deprecated bcrypt API...",
+      "options": [
+        {"label": "Update to bcrypt v4 API", "recommended": true},
+        {"label": "Switch to argon2", "recommended": false},
+        {"label": "Keep current (suppress warning)", "recommended": false}
+      ],
+      "allow_custom": true
+    }
+  ]
+}
+```
+4. **Frontend** renders this as an interactive HTML table/card grid:
+   - Each row: topic name | description | option radio buttons/cards | **notes column**
+   - The **notes column** is always present on every row — a text input that lets the user:
+     - Add additional context/details to accompany their selection
+     - Provide a custom option not listed (override)
+     - Ask a question or request more info on that specific topic
+   - Recommended option is pre-selected/highlighted but user can change
+   - "Submit All" button at bottom
+5. **On submit**: client sends `{"type": "submit_decisions", ...}` with selections AND notes, backend formats as text and sends to Claude via `tmux_manager.send_keys()`
+6. The text sent to Claude would be formatted like:
+```
+Decisions for "Code Review Decisions":
+- Auth module refactor: Update to bcrypt v4 API
+- Error handling: Add retry with backoff
+  Note: "Make sure we handle the 429 case specifically"
+- Logging strategy: [Custom] "Let's discuss this one more - what about structured logging?"
+...
+```
+
+## Custom Interaction Types (CCWeb Protocol)
+
+Beyond the decision grid, define additional structured interaction types that Claude Code skills can output. All use the same detection mechanism (marker in JSONL text or file in `.ccweb/`):
+
+### 1. Decision Grid (primary use case)
+See above. Skill outputs structured JSON, user selects options + adds notes, answers sent back.
+
+### 2. Checklist
+Simpler than a decision grid — just checkboxes with labels. User checks items and submits.
+```json
+{"type": "ccweb:checklist", "title": "Pre-deploy checks", "items": [
+  {"label": "Tests passing", "checked": false},
+  {"label": "Migrations reviewed", "checked": false},
+  {"label": "ENV vars updated", "checked": true}
+]}
+```
+Submitted as: "Checked: Tests passing, Migrations reviewed. Unchecked: ENV vars updated."
+
+### 3. Status Report
+A skill outputs a structured status dashboard. Read-only (no user interaction needed).
+```json
+{"type": "ccweb:status", "title": "Build Status", "items": [
+  {"label": "Unit tests", "status": "pass", "detail": "142/142"},
+  {"label": "Lint", "status": "fail", "detail": "3 errors in auth.py"},
+  {"label": "Type check", "status": "pass", "detail": "0 errors"}
+]}
+```
+Rendered as cards with green/yellow/red indicators.
+
+### 4. Confirmation Dialog
+For critical actions that need explicit user approval with context.
+```json
+{"type": "ccweb:confirm", "title": "Deploy to production?",
+ "description": "This will deploy commit abc123 to prod. 3 migrations pending.",
+ "severity": "high",
+ "actions": [{"label": "Deploy", "value": "yes"}, {"label": "Cancel", "value": "no"}]}
+```
+
+### Detection Mechanism (file-based, primary)
+The Claude Code skill writes a JSON file to a well-known location using the Write tool (which is atomic and reliable — no risk of malformed output or marker splitting):
+
+```
+{session_cwd}/.ccweb/pending/{type}-{timestamp}.json
+```
+
+Example: `.ccweb/pending/grid-1712345678.json`
+
+The backend watches this directory (via polling alongside JSONL monitoring). When a new file appears:
+1. Read and validate the JSON
+2. Send structured WebSocket message to the frontend
+3. Move file to `.ccweb/completed/` after user submits (or `.ccweb/dismissed/` if ignored)
+
+**Why file-based instead of text markers**: Writing a file via Claude's Write tool is a deterministic tool call — always produces valid JSON, no streaming chunk splits, no code-block false positives, easy to debug (`cat` the file). Text markers (`<!--ccweb:grid {json}-->`) are fragile because Claude's output is free-form text that can be malformed, wrapped in code blocks, or split across JSONL entries.
+
+**CRITICAL: Timing — how Claude waits for the user's response**:
+The skill MUST use `AskUserQuestion` after writing the grid file. Without this, Claude writes the file and immediately proceeds — by the time the user sees the grid, Claude is 3 tool calls ahead, and the submitted text arrives as garbage input mid-thought.
+
+Correct flow:
+1. Skill writes grid JSON to `.ccweb/pending/grid-xxx.json` (via Write tool)
+2. Skill IMMEDIATELY calls `AskUserQuestion` with: "I've prepared an option grid for you. Please review it in your CCWeb interface and submit your selections. (Your answers will appear here automatically.)"
+3. `AskUserQuestion` **blocks Claude** — it waits for user input
+4. Backend detects the grid file → sends to frontend via WebSocket
+5. User fills out grid, clicks Submit
+6. Backend sends formatted selection text to Claude via tmux keystrokes
+7. Claude receives the text as the AskUserQuestion response, unblocks, and continues
+
+This is the ONLY correct approach. The skill prompt must enforce steps 1+2 together.
+
+### CCWeb Skill Installation
+Skills are installed **globally** in `~/.claude/commands/` so they're available in every project. No per-repo copying needed.
+
+**`ccweb install`** command auto-installs:
+1. The SessionStart hook (same as ccbot's `ccbot hook --install`)
+2. Global slash commands for all ccweb interaction types:
+   - `~/.claude/commands/option-grid.md` — Decision/option grid
+   - `~/.claude/commands/checklist.md` — Interactive checklist
+   - `~/.claude/commands/status-report.md` — Status dashboard
+   - `~/.claude/commands/confirm.md` — Confirmation dialog
+
+**Example: `~/.claude/commands/option-grid.md`:**
+```markdown
+# Option Grid
+
+When called, research the topics provided and output an option grid for the user.
+
+You MUST do these two steps in sequence:
+
+Step 1: Write the grid as a JSON file using your Write tool to this exact path:
+  {cwd}/.ccweb/pending/grid-{timestamp}.json
+
+Use this schema:
+{"id": "unique-id", "type": "ccweb:grid", "title": "...", "items": [
+  {"topic": "...", "description": "...", "allow_custom": true,
+   "options": [{"label": "...", "recommended": true}, ...]}
+]}
+
+Each item must have: topic, description, options (array with recommended flag),
+allow_custom: true. Always include 2-4 options per topic with one marked as recommended.
+
+Step 2: IMMEDIATELY after writing the file, use AskUserQuestion to ask:
+"I've prepared an option grid. Please review it in your CCWeb interface and submit
+your selections. Your choices will appear here automatically."
+
+This is critical — AskUserQuestion blocks you until the user responds via CCWeb.
+Do NOT proceed without waiting. The user's selections will be sent back as text.
+```
+
+Run `ccweb install` once and all commands are available everywhere.
+
+## Implementation Order
+
+### Phase 1: Project Scaffold + Core Backend
+1. Create `ccweb/` directory structure
+2. Create `pyproject.toml` with deps: `fastapi`, `uvicorn[standard]`, `websockets`, `libtmux`, `aiofiles`, `python-dotenv` — pin same `libtmux` version as ccbot to avoid API breakage
+3. **Create `config.py` FIRST** — this is the foundation. Must expose all attribute names used by forked modules (`tmux_session_name`, `claude_projects_path`, `state_file`, `session_map_file`, etc.) without Telegram deps
+4. **Create `utils.py` SECOND** — `ccweb_dir()` returning `~/.ccweb/`, `atomic_write_json()`
+5. Fork modules from ccbot to `ccweb/backend/core/`: update all `from .config import config` and `from .utils import` paths. `terminal_parser.py` is the only true copy (zero config/utils deps).
+6. Adapt `transcript_parser.py` (remove Telegram expandable quote sentinels)
+7. Adapt `hook.py` — writes to `~/.ccweb/session_map.json`, command is `ccweb hook`
+8. Create simplified `session.py` (client_bindings instead of thread_bindings)
+9. Create `ws_protocol.py` (message type definitions)
+10. Create `server.py` (FastAPI app, WebSocket handler, REST endpoints)
+11. Create `main.py` (CLI entry with `ccweb`, `ccweb install`, `ccweb hook` subcommands)
+12. **Verify**: run `ccweb` — FastAPI starts, WebSocket connects, health check passes
+
+### Phase 2: React Frontend Scaffold
+1. `npm create vite@latest frontend -- --template react-ts`
+2. Install deps: `react-markdown`, `remark-gfm` (markdown rendering), a CSS framework (Tailwind or similar)
+3. Create `protocol.ts` (mirrors WebSocket types)
+4. Create `useWebSocket.ts` hook (connect, reconnect, message dispatch)
+5. Create basic `App.tsx` layout (sidebar + main content area)
+
+### Phase 3: Message Stream + Input
+1. `MessageStream.tsx` - renders messages with role-based styling:
+   - Assistant text → markdown rendered
+   - Thinking → collapsible/expandable block
+   - tool_use → summary line (like "**Read**(file.py)")
+   - tool_result → `<pre>` block (collapsible). Rich rendering (diff viewer, search cards) deferred to v2
+   - User messages → right-aligned or prefixed
+2. `FileUpload.tsx` - document/file upload:
+   - Paperclip (📎) button next to the text input
+   - Accepts: text files, code, Markdown, PDF, Word docs, images (same as ccbot's allowed types)
+   - Upload flow: file sent to backend → saved to `{session_cwd}/docs/inbox/{filename}` → path sent to Claude via tmux as "A file has been saved to docs/inbox/{name}. Read it with your Read tool."
+   - Optional caption/instruction text alongside the upload
+   - Drag-and-drop support on the message area
+   - Image files rendered as inline thumbnails before sending
+3. `MessageInput.tsx` - multi-line text area with:
+   - **Enter = newline** (multi-line input by default)
+   - **Visible Submit button** to send the message
+   - **Ctrl+Enter / Cmd+Enter** keyboard shortcut to submit (optional accelerator)
+   - `/command` forwarding (auto-complete dropdown on `/`)
+   - Command history (Ctrl+Up / Ctrl+Down to cycle through previous messages)
+3. `StatusBar.tsx` - shows Claude's current status (spinner text)
+
+**Note on latency**: JSONL polling at 2s means responses appear in bursts, not token-by-token streaming. The status bar (polled at 1s) provides "Claude is working..." feedback during the gap. This matches ccbot's current latency. True streaming would require monitoring the JSONL file via inotify/watchdog instead of polling — a v2 enhancement.
+
+### Phase 4: Session Management
+The session sidebar replaces Telegram's topic list:
+1. `SessionSidebar.tsx`:
+   - List active sessions (window_id, name, cwd, status indicator)
+   - Click to switch (binds WebSocket to that window, loads history)
+   - **"+ New Session" button** → opens directory picker modal
+   - Kill session: X button on each session (confirms first)
+   - Session status: idle / working / waiting for input (based on status polling)
+2. `DirectoryPicker.tsx` (modal):
+   - File-tree browser (reuses ccbot's directory browsing logic on backend)
+   - Click folders to navigate, "Select" to confirm
+   - Path text input for direct entry
+   - Recent directories list (persisted in localStorage)
+   - Optional session name field
+3. Backend:
+   - `POST /api/sessions` → create_window + start Claude + wait for session_map
+   - `GET /api/sessions` → list active sessions
+   - `DELETE /api/sessions/{window_id}` → kill_window + cleanup
+   - WebSocket broadcasts session list changes to all connected clients
+
+### Phase 5: Interactive UI Components
+1. **Backend: structured UI parser** (`ui_parser.py`):
+   - `terminal_parser.py` returns raw text (`InteractiveUIContent.content` is a string with Unicode checkboxes like `☐✔☒`, cursor markers, etc.)
+   - New `ui_parser.py` module parses this raw text into structured data:
+     - AskUserQuestion: extract option labels + checked/unchecked state from `☐`/`✔`/`☒` markers
+     - PermissionPrompt: extract the action description + yes/no options
+     - ExitPlanMode: extract plan summary text
+     - BashApproval: extract the bash command being requested
+   - This is **fragile screen-scraping** — Claude Code can change its terminal UI format. The parser must be defensive with fallback to raw text display.
+   - WebSocket message includes both structured data (when parsing succeeds) AND raw text (always, as fallback)
+2. `InteractiveUI.tsx`:
+   - When `type: "interactive_ui"` arrives via WebSocket:
+     - If structured data present: render as clickable cards/buttons
+     - If only raw text: render in a `<pre>` block with generic navigation buttons (like ccbot's keyboard)
+     - AskUserQuestion → clickable option cards
+     - PermissionPrompt → "Allow" / "Deny" buttons with action description
+     - ExitPlanMode → "Proceed" / "Edit" buttons
+   - Clicking sends `send_key` back (Enter, Escape, Space, Tab, arrows)
+   - **Stale UI guard**: before sending a key, backend re-captures the pane and verifies the interactive UI is still showing. If not, discard the click and notify the user "This prompt has expired."
+3. Backend: detect interactive UIs via `terminal_parser.py`, parse via `ui_parser.py`, send structured data + raw text over WebSocket
+
+### Phase 6: Decision Grid
+1. `DecisionGrid.tsx`:
+   - Renders grid items as cards in a table/grid layout
+   - Each item shows topic, description, and radio buttons for options
+   - Recommended option highlighted
+   - "Submit All" button
+   - Overlay/modal that slides over the message stream
+2. Backend: poll `.ccweb/pending/` directory alongside JSONL monitoring (same poll loop, no extra loop)
+   - On new file: validate JSON schema, send to frontend, move to `.ccweb/completed/` on submit
+   - On invalid JSON: log warning, move to `.ccweb/failed/`, notify frontend with error
+   - Stale file cleanup: files older than 1 hour in `pending/` are moved to `failed/`
+   - `.ccweb/pending/` directory is auto-created by the backend on session creation
+3. Define the Claude Code skill contract (JSON schema for decision files)
+4. **Timing**: the skill MUST call AskUserQuestion after writing the file to block Claude (see Detection Mechanism section above)
+
+### Phase 7: Command Palette & Skill Picker
+1. **Command auto-complete in MessageInput**:
+   - Typing `/` in the text input triggers a dropdown above the input
+   - Built-in commands shown with descriptions: `/clear` (Clear history), `/compact` (Compact context), `/model` (Switch model), `/fast` (Toggle fast mode), `/plan` (Enter plan mode), `/cost` (Show usage), `/help`, `/memory`, `/config`, etc.
+   - Click to insert and send, or keep typing to filter
+2. **Repo skills discovery**:
+   - Backend endpoint: `GET /api/sessions/{window_id}/skills`
+   - Reads `{session_cwd}/.claude/commands/` directory for custom slash commands
+   - Parses command files to extract name + description (first line of the file is typically the description)
+   - Frontend shows these in the command dropdown, grouped under "Project Commands" separately from "Built-in Commands"
+   - Skills refresh when switching sessions (different repos have different skills)
+3. **Dropdown command selector**: A `▾` button next to the text input that opens the full command/skill list without needing to type `/`. Provides discoverability — browse all available commands and skills via click. Same grouped list as the auto-complete (Built-in Commands | Project Commands).
+4. **Toolbar quick-actions**: Persistent buttons above the message input for frequent actions:
+   - `/esc` (interrupt Claude) — prominent, always visible
+   - Command palette button (opens full command/skill list)
+   - Screenshot button (captures terminal as image, useful for sharing)
+
+### Phase 8: Message Filters
+1. **Filter bar** at the top of the message stream with toggleable chips:
+   - **All** — everything (default)
+   - **Chat** — only user messages + assistant text (hides tool_use, tool_result, thinking)
+   - **No thinking** — everything except thinking blocks
+   - **Tools** — only tool_use + tool_result (see what Claude did without the prose)
+2. Filter state persisted per session (localStorage) — each session can have its own filter
+3. Implementation: each message already has `content_type` from the JSONL parse, so filtering is a simple frontend predicate on the message list. No backend changes needed.
+
+### Phase 9: Documentation Wiki
+**Single source of truth**: Markdown files in `ccweb/docs/` serve both as repo-readable docs AND as the in-app wiki. No content duplication.
+
+**Doc structure** (`ccweb/docs/`):

+
+**Every doc file has:**
+- YAML frontmatter: `title`, `description`, `order` (for sidebar sorting)
+- Table of contents (auto-generated from headings)
+- Internal links using relative paths: `[Option Grid](../features/option-grid.md)`
+- Works when browsing on GitHub/filesystem AND in the web UI
+
+**In-app wiki (`/wiki` route in frontend):**
+- `WikiPage.tsx` — renders a single doc page with react-markdown
+- `WikiSidebar.tsx` — navigation tree built from the docs/ directory structure
+- Backend: `GET /api/docs` returns the doc tree (filenames + frontmatter)
+- Backend: `GET /api/docs/{path}` returns raw markdown content for a specific file
+- Internal links rewritten to `#/wiki/...` routes in the web UI
+- Search: full-text search across all doc files (backend endpoint)
+- Breadcrumb navigation at top of each page
+
+### Phase 10: Responsive Design (Desktop + Tablet)
+Target: Chrome for Windows (desktop) + Chrome for Android on Samsung Z Fold 7 (tablet mode).
+
+1. **Layout breakpoints**:
+   - Desktop (>1024px): sidebar visible + main content area side by side
+   - Tablet (768-1024px): sidebar as hamburger drawer, full-width content
+   - The Z Fold 7 in tablet mode is ~7.6" at ~904px width → tablet layout
+2. **Touch-friendly**:
+   - All interactive elements minimum 44x44px touch targets
+   - Swipe gestures: swipe right to open sidebar, swipe left to close
+   - Decision grid options as large tap targets (cards, not tiny radio buttons)
+   - Submit button prominently sized
+3. **Input handling**:
+   - On tablet: virtual keyboard push-up handling (input stays visible above keyboard)
+   - Auto-resize text area as you type
+4. **CSS approach**: Tailwind CSS with responsive utilities (`md:`, `lg:` prefixes)
+   - Flexbox layout that reflows naturally
+   - No fixed pixel widths on content areas
+
+### Phase 11: Quality-of-Life Features
+
+1. **Browser notifications** (`useNotifications.ts`):
+   - Request notification permission on first visit
+   - Push notification when: Claude finishes a task (stop_reason set), interactive UI appears (AskUserQuestion, permission), subagent completes
+   - Only fires when the tab is not focused or screen is off
+   - Notification click brings you to the correct session
+   - On Android/tablet: works with Chrome's built-in notification system
+
+2. **Context & cost indicator** (`ContextBar.tsx`):
+   - Persistent badge in the status bar: "Context: 34% | $2.15"
+   - Backend periodically captures `/usage` output via terminal_parser's `parse_usage_output()`
+   - Or: parse the status line chrome (bottom bar of Claude Code pane shows model + context %)
+   - Color changes: green (<50%), yellow (50-80%), red (>80%)
+   - Click to expand full usage details (token counts, rate limits)
+
+3. **Session persistence on page reload**:
+   - On WebSocket connect, backend sends full session list + which session was last active
+   - Client stores last active session in localStorage
+   - On reconnect: auto-binds to last session, requests message history via `get_recent_messages()`
+   - Messages load from JSONL (the full history is always there), so no data loss on browser close/refresh
+
+4. **Copy buttons on code blocks** (`CodeBlock.tsx`):
+   - One-click copy icon (📋) on every fenced code block, inline code, diff output, and command output
+   - "Copied!" toast feedback
+   - For diffs: option to copy just the new content (without diff markers)
+   - Uses `navigator.clipboard.writeText()`
+
+5. **Connection status indicator**:
+   - Small badge in the top bar: 🟢 Connected | 🟡 Reconnecting | 🔴 Disconnected
+   - On disconnect: auto-reconnect with exponential backoff (1s, 2s, 4s, 8s, max 30s)
+   - On reconnect: replays any missed messages (backend tracks last-delivered offset per client)
+   - Manual "Reconnect" button when auto-reconnect fails
+
+6. **Session rename**:
+   - Double-click session name in sidebar → inline edit field
+   - Or right-click → "Rename" context menu
+   - Backend calls `tmux_manager.rename_window()` + updates display name in session state
+   - Updates reflected immediately across all connected clients
+
+7. **Export conversation** (`ExportButton.tsx`):
+   - Button in session header: "Export" → dropdown: Markdown / JSON / Plain Text
+   - **Markdown**: formatted conversation with headers, code blocks, tool summaries (ready for sharing)
+   - **JSON**: raw JSONL entries (for programmatic use)
+   - **Plain text**: stripped of all formatting
+   - Filters applied: export respects current message filter (e.g., "Chat only" exports only user+assistant text)
+   - Downloads as a file: `{session-name}-{date}.md`
+
+### Phase 12: Polish & UX
+1. Auto-scroll behavior (pause on scroll-up, resume on new messages)
+2. Expandable blocks for thinking/tool results (click to expand/collapse)
+3. Image rendering for tool_result images (base64 → inline img)
+4. WebSocket reconnection (auto-reconnect + replay missed messages)
+5. Keyboard shortcuts: Escape to interrupt, Ctrl+K for command palette, Ctrl+N for new session
+6. Dark/light theme toggle (default dark, matching terminal aesthetic)
+7. Notification badge on sessions with unread messages (when viewing a different session)
+
+## Technical Issues to Address (from review)
+
+1. **SessionMonitor single callback**: Wrap in a fan-out broadcaster. One callback registered, it iterates all connected WebSocket clients and sends. Single-user means this is simple.
+
+2. **Byte offset + WebSocket delivery**: Since single-user, offsets persist after `ws.send()` (fire-and-forget). On reconnect, client sends its last-received message timestamp; backend replays from that point via `get_recent_messages()` with byte offset.
+
+3. **WebSocket keepalive**: Add ping/pong frames (FastAPI/Starlette supports this natively with `websocket.send_json` + periodic pings). 30s interval.
+
+4. **Error message type**: Add `{"type": "error", "code": "...", "message": "..."}` to the WebSocket protocol for backend failures (tmux down, session_map corrupt, etc.).
+
+5. **`session_map.json` read race**: Use `fcntl.flock` for reads too (shared lock), matching the hook's exclusive lock on writes. Or: read with retry on `JSONDecodeError`.
+
+6. **`config.py` import chain**: The adapted `config.py` for ccweb does NOT import Telegram config. All "copy verbatim" modules import from `ccweb.backend.core.config` (the new one), not the old ccbot config. This breaks the Telegram dependency chain entirely.
+
+7. **WebSocket protocol additions**:
+   - `{"type": "ping"}` / `{"type": "pong"}` — keepalive
+   - `{"type": "error", "code": "...", "message": "..."}` — backend errors
+   - `{"type": "replay_request", "since_timestamp": "..."}` — client reconnection catch-up
+   - `{"type": "replay", "messages": [...]}` — server replay response
+
+## V2 Roadmap (deferred features)
+
+Saved as `ccweb/docs/architecture/v2-roadmap.md` alongside the design plan.
+
+### Rich Tool Output (from Phase 7.5, deferred)
+- **File diff viewer** (`DiffViewer.tsx`): Edit tool diffs rendered with green/red line highlighting, collapsible per file
+- **Progress tracker** (`ProgressTracker.tsx`): TodoWrite rendered as persistent checkbox panel, pinned above message stream
+- **Search results cards** (`SearchResults.tsx`): WebSearch as cards with title/snippet/link, Grep as highlighted matches
+- **Destructive action warning**: Permission prompts for `rm`, `reset --hard` etc. rendered with red highlight border
+
+### Subagent Activity Tracking (from Phase 7.6, deferred)
+- Collapsible task cards in message stream (header: "Agent: {description}" with running/complete indicator)
+- Subagent status badge ("2 agents running")
+- Future: monitor subagent JSONL files directly for real-time streaming
+
+### Saved Prompts Library (from Phase 8, deferred)
+- Prompt Library UI with title, category, preview, fuzzy search
+- Variable placeholders: `{{filename}}`, `{{description}}` → form fill on insert
+- Global prompts (`~/.ccweb/prompts/`) + per-project prompts (`{project}/.ccweb/prompts/`)
+- CRUD API endpoints
+
+### Creative UX Explorations
+Ideas from the creative review to explore for v2:
+- **Message threading**: Nest question/answer exchanges visually (Slack-style threads)
+- **Optimistic input**: Show user's message immediately with pending indicator before tmux round-trip
+- **Session timeline scrubber**: Horizontal minimap of session phases (thinking/tool use/conversation/idle), click to jump
+- **Live file preview pane**: Split view showing file's current state after Edit, not just the diff
+- **Pinned messages**: Pin key decisions/outputs to the top of a session
+- **Session heatmap**: Which sessions were active when, token spend per session
+- **Quick reactions on tool results**: Thumbs-up/flag individual outputs as feedback
+- **Minimap**: VS Code-style vertical scroll overview of message density and type
+- **Keyboard-first navigation**: Linear-style shortcuts (G+S for sessions, G+P for prompts)
+- **Stackable message filters**: Combine filters (e.g., "chat + tools but not thinking")
+
+### Decision Grid v2 Improvements
+- **Keyboard navigation**: Arrow keys between cells, Enter to select, Tab to notes column
+- **Comparison mode**: Select two options, see side-by-side with differences highlighted
+- **Fuzzy search in saved prompts**: Raycast/Alfred-style instant matching
+- **Collapsible file-change groups**: GitHub-style when diffs are numerous
+

+
+## Startup Health Checks & Error UX
+
+On startup, `ccweb` runs validation before accepting connections:
+
+1. **tmux running?** — Check `tmux list-sessions`. If not: print clear error "tmux is not running. Start tmux first: `tmux new -s ccbot`"
+2. **Hook installed?** — Check `~/.claude/settings.json` for SessionStart hook pointing to `ccweb hook`. If not: print warning "SessionStart hook not installed. Run `ccweb install` first. Sessions will not be monitored."
+3. **State directory exists?** — Create `~/.ccweb/` if missing.
+4. **Config valid?** — Validate .env loaded, required vars present.
+
+On WebSocket connect, send a `{"type": "health", "status": {...}}` message with:
+- `tmux_running: bool`
+- `hook_installed: bool`
+- `sessions_found: int`
+- `warnings: string[]`
+
+Frontend renders a diagnostic banner for any issues: "Hook not installed — run `ccweb install`" with a one-click fix button (calls backend endpoint that installs the hook).
+
+**Error states in the UI**:
+- tmux not running → red banner: "tmux is not running"
+- WebSocket disconnected → yellow banner with reconnect button
+- Session killed externally → session shows "(ended)" in sidebar with explanation
+- Hook not installed → orange banner with install button
+- No sessions → helpful empty state: "No sessions yet. Click + New Session to start."
+
+## Backend Server Design (`server.py`)
+
+```python
+# FastAPI app serves:
+# - GET / → React static files (production) or proxy to Vite dev server
+# - WebSocket /ws → bidirectional real-time communication
+# - GET /api/sessions → list active sessions
+# - POST /api/sessions → create new session
+# - DELETE /api/sessions/{window_id} → kill session
+
+# On startup:
+# 1. Initialize TmuxManager, SessionManager, SessionMonitor
+# 2. Start SessionMonitor polling loop
+# 3. Start status polling loop (1s interval, like ccbot)
+# 4. Set message callback to broadcast to connected WebSocket clients
+
+# WebSocket handler:
+# - On connect: send current session list + bind to active window
+# - On message: dispatch by type (send_text, send_key, submit_decisions, etc.)
+# - On disconnect: clean up client binding
+
+# Message callback (from SessionMonitor):
+# - For each NewMessage, find connected clients bound to that window
+# - Serialize and send via WebSocket
+# - For AskUserQuestion/ExitPlanMode tool_use: capture terminal, 
+#   parse interactive UI, send structured data instead of raw text
+```
+
+## Hosting & Remote Access
+
+The FastAPI server serves both the API (WebSocket + REST) and the built React static files on a **single port** (default 8765). No separate frontend hosting needed.
+
+**With Tailscale (user's current setup):**
+- Server binds to `0.0.0.0:8765`
+- Access from any device on the tailnet: `http://<machine-name>:8765`
+- Tailscale ACLs control access (no separate auth needed if tailnet is trusted)
+- Optional HTTPS: `tailscale cert` + uvicorn SSL config, or `tailscale serve --bg 8765` for automatic HTTPS at `https://<machine>.tail-net.ts.net`
+
+**Server config** (`.env` file in `~/.ccweb/` or env vars — set once, requires restart):
+```bash
+CCWEB_HOST=0.0.0.0          # Bind address
+CCWEB_PORT=8765              # Port
+CCWEB_AUTH_TOKEN=            # Optional bearer token (empty = no auth, rely on Tailscale)
+TMUX_SESSION_NAME=ccbot      # Tmux session name
+CLAUDE_COMMAND=claude         # Command to start Claude Code
+CCWEB_BROWSE_ROOT=           # Starting dir for session browser (empty = home)
+MONITOR_POLL_INTERVAL=2.0    # Seconds between JSONL polls
+CCWEB_SHOW_HIDDEN_DIRS=false # Show dot-dirs in browser
+# Memory monitoring
+CCWEB_MEMORY_MONITOR=true
+CCWEB_MEM_AVAIL_WARN_MB=1024
+CCWEB_MEM_AVAIL_INTERRUPT_MB=512
+CCWEB_MEM_AVAIL_KILL_MB=256
+```
+
+**User preferences** (settings page in the web UI — changeable live, persisted to `~/.ccweb/preferences.json`):
+- Theme: dark / light
+- Default message filter: All / Chat / No thinking / Tools
+- Show hidden directories in browser
+- Auto-scroll behavior (pause on scroll-up, resume on new messages)
+- Submit shortcut: Ctrl+Enter / Cmd+Enter toggle
+
+The settings page is accessible via a gear icon in the sidebar. Changes take effect immediately without restart.
+
+**Production serving:**
+- `uvicorn ccweb.backend.main:app --host 0.0.0.0 --port 8765`
+- React app built with `npm run build` → static files served by FastAPI's `StaticFiles` mount
+- In dev: Vite dev server on :5173 proxies API calls to FastAPI on :8765
+- **IMPORTANT**: Vite proxy must explicitly enable WebSocket: `server.proxy["/ws"] = { target: "ws://localhost:8765", ws: true }` in `vite.config.ts`. Without `ws: true`, WebSocket upgrade handshake fails silently.
+
+## Per-Project Setup (What a new repo needs)
+
+**Short answer**: Run `ccweb install` once, and new projects work automatically.
+
+**What `ccweb install` sets up globally (one time):**
+- `~/.claude/settings.json` → SessionStart hook (writes session_map.json when Claude starts)
+- `~/.claude/commands/option-grid.md` → option grid slash command
+- `~/.claude/commands/checklist.md`, `status-report.md`, `confirm.md` → other interaction commands
+
+**What a new project gets for free (zero setup):**
+- Session creation via ccweb's directory browser
+- Real-time message streaming
+- All interactive UI handling (AskUserQuestion, permissions, plan mode)
+- All built-in /commands and the global ccweb skills
+- File upload, message filters, subagent tracking, diff viewer, etc.
+
+**Optional per-project enhancements** (add to the project's `CLAUDE.md` if you want Claude to proactively use ccweb features):
+```markdown
+## CCWeb Integration
+- When presenting multiple options/decisions to the user, use the /option-grid command
+- When reporting build/test status, use the /status-report command
+- For critical destructive actions, use the /confirm command before proceeding
+```
+
+**Optional per-project prompts** (for the Saved Prompts library):
+- Create `{project}/.ccweb/prompts/deploy.md`, `review.md`, etc.
+- These show up in the prompt library only when that project's session is active
+
+**Per-project CCWeb instructions** (avoids mutating CLAUDE.md directly):
+Instead of writing into CLAUDE.md (which creates git noise, merge conflicts, and meaningless diffs), ccweb creates a separate `.ccweb/instructions.md` file that CLAUDE.md can reference:
+
+1. **On session creation**: If the project has no `.ccweb/instructions.md`, a subtle banner appears: "Enable CCWeb features for this project?" → click to create.
+2. **"Setup CCWeb" button**: Available in the session sidebar (per-session gear icon). One click creates/updates `.ccweb/instructions.md`.
+3. **The file** contains ccweb-specific instructions for Claude:
+```markdown
+## CCWeb Integration
+- When presenting multiple options/decisions to the user, use /option-grid
+- When reporting build/test/deploy status, use /status-report
+- For interactive checklists, use /checklist
+- For critical destructive actions, use /confirm before proceeding
+```
+4. **CLAUDE.md reference** (optional, user adds manually if they want): Add one line to CLAUDE.md: `See @.ccweb/instructions.md for CCWeb integration.`
+5. `.ccweb/` can be `.gitignore`d if the user doesn't want it tracked — no git noise.
+6. **Backend**: `POST /api/sessions/{window_id}/setup-ccweb` → creates `.ccweb/instructions.md` in the session's working directory.
+
+**Summary**: A bare repo with no ccweb-specific files works perfectly. The CLAUDE.md management is an optional convenience — one click to enable, auto-updated as ccweb evolves, and clearly delimited so it doesn't interfere with your own CLAUDE.md content.
+
+## Portability
+
+The `ccweb/` folder is **completely self-contained** — no imports from the parent ccbot-workshop repo. All reused modules are copied into `ccweb/backend/core/`. To make it a standalone repo:
+
+1. Copy `ccweb/` to a new location
+2. `git init` → it's a new repo
+3. Has its own `pyproject.toml`, `package.json`, README, docs, etc.
+4. No changes needed — everything works out of the box
+
+The only shared resource is the tmux session itself. State is fully separate:
+- ccbot uses `~/.ccbot/` (state.json, session_map.json, monitor_state.json)
+- ccweb uses `~/.ccweb/` (its own state.json, session_map.json, monitor_state.json)
+- Both can monitor the same tmux windows without conflict (read-only JSONL access)
+- The SessionStart hook must be `ccweb hook` (writes to `~/.ccweb/`), not `ccbot hook`
+- If running both simultaneously, install BOTH hooks in `~/.claude/settings.json`
+
+## Key Reusable Methods from session.py
+
+The adapted `session.py` will keep these critical methods (changing only the binding model):
+- `resolve_stale_ids()` — re-resolve window IDs after tmux restart
+- `load_session_map()` — read hook-generated session_map.json
+- `get_window_state()` / `clear_window_session()` — window state management
+- `send_to_window()` — send text + auto-resume Claude if exited
+- `get_recent_messages()` — retrieve history with byte-range support
+- `resolve_session_for_window()` — window_id → ClaudeSession resolution
+- `wait_for_session_map_entry()` — poll for hook to fire after window creation
+- `find_users_for_session()` → renamed `find_clients_for_session()` — route incoming messages to connected WebSocket clients
+
+**Binding model change**: Replace `thread_bindings: dict[int, dict[int, str]]` (user_id → {thread_id → window_id}) with `client_bindings: dict[str, str]` (client_id → window_id). Each WebSocket connection has a unique client_id and can be bound to one window at a time.
+
+## Verification Plan
+
+1. **Backend standalone**: Start server, connect WebSocket client (wscat), verify session list, create session, send text, receive messages
+2. **Frontend dev**: `npm run dev` in frontend/, verify React app loads, WebSocket connects
+3. **End-to-end**: Create session via UI, send a message, see Claude's response stream in, interact with AskUserQuestion via clickable options
+4. **Decision grid**: Manually create a test `.ccweb/decisions/test.json`, verify it renders in the frontend, submit selections, verify text arrives in Claude's tmux pane
+5. **Linting**: `ruff check` + `ruff format` + `pyright` on all Python files in `ccweb/backend/`

+description: Deferred features and future enhancements for CCWeb
+order: 2
+---
+
+# CCWeb V2 Roadmap
+
+Features deferred from v1, organized by category.
+
+## Table of Contents
+
+- [Rich Tool Output](#rich-tool-output)
+- [Subagent Activity Tracking](#subagent-activity-tracking)
+- [Saved Prompts Library](#saved-prompts-library)
+- [Creative UX Explorations](#creative-ux-explorations)
+- [Decision Grid v2 Improvements](#decision-grid-v2-improvements)
+- [Performance: Streaming via inotify](#performance-streaming-via-inotify)
+
+---
+
+## Rich Tool Output
+
+Replace `<pre>` blocks with interactive, tool-specific rendering:
+
+- **File diff viewer** (`DiffViewer.tsx`): Edit tool diffs rendered with green/red line highlighting, collapsible per file. One of the most frequent tool outputs — huge UX improvement.
+- **Progress tracker** (`ProgressTracker.tsx`): TodoWrite rendered as persistent checkbox panel, pinned above message stream. Updates in real-time as Claude marks items complete.
+- **Search results cards** (`SearchResults.tsx`): WebSearch as cards with title/snippet/link. Grep as file paths with highlighted match lines. Glob as file tree-style list.
+- **Destructive action warning**: Permission prompts for `rm`, `reset --hard`, `drop`, `delete` rendered with red highlight border and explicit warning text.
+
+## Subagent Activity Tracking
+
+Better visibility into Claude's Agent/Task tool usage:
+
+- Collapsible task cards in message stream (header: "Agent: {description}" with running/complete indicator)
+- Visually nested/indented from the parent conversation
+- Subagent status badge ("2 agents running") that updates in real-time
+- Future: monitor subagent JSONL files directly for real-time streaming of subagent activity (not just final results)
+
+## Saved Prompts Library
+
+System for creating, storing, and reusing frequently-used prompts:
+
+- **Prompt Library UI** with title, category, preview, fuzzy search (Raycast/Alfred-style)
+- **Variable placeholders**: `{{filename}}`, `{{description}}` — form pops up on insert to fill them in
+- **Global prompts** in `~/.ccweb/prompts/` + **project prompts** in `{project}/.ccweb/prompts/`
+- CRUD API endpoints: `GET/POST/PUT/DELETE /api/prompts`
+
+## Creative UX Explorations
+
+Ideas from design review to explore:
+
+- **Message threading**: Nest question/answer exchanges visually (Slack-style threads)
+- **Optimistic input**: Show user's message immediately with pending indicator before tmux round-trip
+- **Session timeline scrubber**: Horizontal minimap of session phases (thinking/tool use/conversation/idle), click to jump
+- **Live file preview pane**: Split view showing file's current state after Edit, not just the diff
+- **Pinned messages**: Pin key decisions/outputs to the top of a session
+- **Session heatmap**: Which sessions were active when, token spend per session
+- **Quick reactions on tool results**: Thumbs-up/flag individual outputs as feedback
+- **Minimap**: VS Code-style vertical scroll overview of message density and type
+- **Keyboard-first navigation**: Linear-style shortcuts (G+S for sessions, G+P for prompts)
+- **Stackable message filters**: Combine filters (e.g., "chat + tools but not thinking")
+
+## Decision Grid v2 Improvements
+
+- **Keyboard navigation**: Arrow keys between cells, Enter to select, Tab to notes column
+- **Comparison mode**: Select two options, see side-by-side with differences highlighted
+- **"Explain this option" button**: Per-row button that asks Claude for elaboration without losing context
+- **Collapsible file-change groups**: GitHub-style when diffs are numerous
+
+## Performance: Streaming via inotify
+
+Replace 2-second JSONL polling with file-system event monitoring:
+
+- Use `watchdog` or `inotify` to detect JSONL file changes instantly
+- Reduces response latency from 2s+ to near-instant
+- Status bar already provides 1s feedback, but streaming content would be dramatically better
+- Requires careful handling of partial writes (same partial-line logic as current monitor)

Subject: [PATCH 31/57] Fix bugs found by adversarial code review

- Fix stale UI guard blocking Escape-to-interrupt: Escape key is now
  always allowed through (it's the interrupt key), guard only applies
  to interactive UI navigation keys
- Add lookup_window_state() that doesn't auto-create phantom entries,
  use it in _handle_new_message to prevent state pollution and disk
  I/O churn from create-delete cycles
- Remove dead code find_clients_for_session (misleading name, never called)
- Implement decision grid file polling in status_poll_loop: watches
  .ccweb/pending/*.json, validates JSON, sends to frontend, moves to
  completed/ or failed/
- Add submit_decisions WebSocket handler: formats user selections as
  text and sends to Claude via tmux, moves grid files to completed/

Subject: [PATCH 32/57] Fix packaging: restructure for correct wheel build

Found by adversarial import chain review:

- Move backend/ under ccweb/ccweb/ so hatch builds a proper wheel
  with the ccweb.backend module hierarchy matching the entry point
- Add ccweb/__init__.py as top-level package marker
- Fix pyproject.toml: packages = ["ccweb"], inline readme (no missing file)
- Fix static files path in server.py (extra parent level after restructure)
- Fix CLI dispatch: `ccweb garbage` now shows error instead of silently
  starting the server

Subject: [PATCH 33/57] Fix silent message drops, grid reconnection, and send
 ACK

Found by fresh adversarial data flow review:

- Add debug logging when message routing skips a client due to missing
  window_state (previously silently continued, making dropped messages
  invisible)
- Clear _sent_grid_files on new WebSocket connection so reconnecting
  clients can see pending decision grid files
- Add send_ack response on successful text send so the frontend knows
  the message was delivered to Claude

Subject: [PATCH 34/57] Fix protocol completeness and silent error handling

Found by fresh adversarial protocol review:

- Add WsPong, WsHistory, WsSendAck dataclasses to ws_protocol.py,
  replacing hardcoded raw dicts in server.py
- Remove dead code: WsReplay and CLIENT_REPLAY_REQUEST (replay not
  implemented, deferred to v2)
- Replace all 5 silent `except Exception: pass` blocks with debug
  logging so dead WebSocket clients don't silently swallow errors
- Fix shutdown: await _status_task cancellation properly, clear
  module-level state (_clients, _client_bindings, _sent_grid_files)
  to prevent test pollution

Also confirmed by install/run review: all imports resolve, pip install
succeeds, entry point works, no remaining ccbot references in code paths.

Subject: [PATCH 35/57] Add React frontend (Phase 2-3): message stream,
 sessions, interactive UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

React + TypeScript + Vite + Tailwind frontend with:

Components:
- App.tsx: main layout with sidebar + content area
- SessionSidebar.tsx: session list, create/kill, health warnings
- MessageStream.tsx: styled message display with markdown rendering,
  auto-scroll, copy buttons on code blocks, role-based styling
- MessageInput.tsx: multi-line textarea, visible Submit button,
  Ctrl+Enter shortcut, Escape toolbar button
- InteractiveUI.tsx: renders AskUserQuestion as clickable option cards,
  PermissionPrompt as Allow/Deny buttons, ExitPlanMode as Proceed/Edit,
  with raw-text fallback + navigation keyboard for unknown UI types
- FilterBar.tsx: toggleable chips (All/Chat/No Thinking/Tools)
- ExpandableBlock.tsx: collapsible sections for thinking/tool results
- StatusBar.tsx: connection status indicator + Claude status text

Hooks:
- useWebSocket.ts: WebSocket connection with auto-reconnect (exponential
  backoff), 30s keepalive pings, typed message dispatch
- useSession.ts: session state, message history, filter logic

Protocol:
- protocol.ts: mirrors ws_protocol.py — all server/client message types

Config:
- Vite proxy: ws: true for WebSocket, /api proxy to FastAPI
- Dark terminal theme (Catppuccin-inspired)
- TypeScript strict mode, builds clean

Subject: [PATCH 36/57] Fix frontend bugs found by adversarial code review
 (Round 1)

Critical fixes:
- Add DecisionGrid component: full modal overlay with option cards,
  notes column per row, submit/dismiss. Wired into App.tsx + useSession
- Add decision_grid handler in useSession.ts (was silently dropped)
- Fix stale closure: use activeWindowIdRef instead of closing over state,
  removing [activeWindowId] dependency from handleServerMessage
- Gate history response by window_id to prevent wrong-session display
  on rapid session switching

WebSocket fixes:
- Guard reconnect timer against unmount (mountedRef prevents orphaned
  timers and leaked connections during HMR)
- send() now returns boolean so caller can detect dropped messages

Cleanup:
- Remove duplicate ConnectionStatus type (components/types.ts), import
  from useWebSocket.ts canonical export instead
- StatusBar imports from hook instead of deleted types.ts

Subject: [PATCH 37/57] Fix bugs from adversarial reviews (Round 1 backend +
 Round 2 frontend)

Backend fixes:
- Catch UnicodeDecodeError in session_monitor (corrupted byte offset
  mid-UTF8 char was blocking ALL sessions from being monitored)
- Per-client grid tracking replaces global _sent_grid_files (prevents
  duplicate grids to existing clients on reconnect, allows multi-client)
- Interactive UI dedup: don't re-send same UI content every second
- resolve_session_for_window uses lookup_window_state (no phantom entries)
- Clean up per-client state on disconnect

Frontend fixes:
- DecisionGrid resets row state when grid prop changes (prevents crash
  if new grid has fewer items than previous)
- Clear messages/status/UI on session switch (prevents stale messages
  from previous session showing during history load)
- Add clearSessionState to useSession return type

Subject: [PATCH 38/57] Fix DecisionGrid stale rows crash on new grid (Round 3)

Use key={grid.id} on DecisionGrid to force remount when a new grid
arrives. This eliminates the useEffect-based state reset which had a
one-render-cycle window where rows[i] could be undefined if the new
grid had more items than the old one, causing a TypeError crash.

Subject: [PATCH 39/57] Add command palette and skill discovery (Phase 7)

Backend:
- GET /api/sessions/{window_id}/skills: discovers slash commands from
  the session's .claude/commands/ directory (name + first-line description)
- GET /api/browse?path=: directory browser for session creation

Frontend:
- CommandPalette.tsx: dropdown with grouped commands (Project Commands
  + Built-in Commands), keyboard navigation (arrow keys + Enter),
  fuzzy filtering as you type
- MessageInput now triggers palette on "/" at start of line, or via
  "/ Commands" toolbar button
- 15 built-in Claude Code commands defined with descriptions
- Project commands fetched from backend on session switch
- Palette positioned above input with smooth keyboard interaction

From c2c1353ee07c9d717ca088a7bc5c98e09638d66a Mon Sep 17 00:00:00 2001
From: Claude <noreply@anthropic.com>
Date: Sat, 11 Apr 2026 02:32:10 +0000
Subject: [PATCH 40/57] Fill gaps from plan audit: file upload, directory
 picker, images, shortcuts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gaps identified by plan-vs-implementation audit. Fixes for phases 3-7:

Phase 3 gap — FileUpload:
- New FileUpload.tsx: paperclip button with drag-and-drop support
- New POST /api/sessions/{window_id}/upload: saves to docs/inbox/,
  sends file path to Claude via tmux

Phase 4 gap — DirectoryPicker:
- New DirectoryPicker.tsx: full modal with file-tree browser using
  GET /api/browse, parent navigation, path text input, session name field
- SessionSidebar simplified: "+ New" now opens DirectoryPicker overlay

Phase 3 gap — Command history:
- Ctrl+Up/Down in MessageInput cycles through previously sent messages

Phase 7 gap — Screenshot button:
- New GET /api/sessions/{window_id}/screenshot endpoint (captures pane text)
- Screenshot button in MessageInput toolbar

Phase 3/12 gap — Image rendering:
- WsMessage now carries images field (base64-encoded from tool_result)
- server.py passes image_data through to WebSocket clients
- MessageStream renders inline images below message content

Phase 12 gap — Keyboard shortcuts:
- Ctrl+N: open new session (DirectoryPicker)

Subject: [PATCH 41/57] Fix CommandPalette crash and Enter key interception

- Clamp selectedIndex on Enter to prevent out-of-bounds crash when
  filter shrinks the command list faster than state updates
- Only register global keydown handler when palette is visible,
  preventing Enter interception after palette closes
- Memoize allCommands array in App.tsx to prevent unnecessary
  CommandPalette re-renders and handler re-registrations

Subject: [PATCH 42/57] Fix missing dependency, skill fetch race, and scroll
 targeting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend:
- Add python-multipart to pyproject.toml dependencies (required by
  FastAPI's UploadFile — app crashed on startup without it)

Frontend:
- Fix skill fetch race condition: add AbortController to cancel stale
  fetches when rapidly switching sessions
- Fix CommandPalette scrollIntoView: use data-cmd-index attribute
  instead of child index (group headers shifted indices, causing wrong
  element to scroll into view)
- Memoize allCommands with useMemo to prevent unnecessary re-renders

 (R2 backend)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Wrap grid file rename in try/except FileNotFoundError to handle
  race where submit handler already moved the file
- Validate window_id is non-empty in CLIENT_SWITCH_SESSION handler
  (prevents empty binding causing wasted poll work)
- Eliminate double is_interactive_ui + extract_interactive_content
  call — use single extract_interactive_content, fix indentation

Subject: [PATCH 44/57] Fix submit_decisions rename race (R3 backend review)

Wrap grid file rename in CLIENT_SUBMIT_DECISIONS handler with
try/except FileNotFoundError, matching the same fix already applied
to _check_decision_grids. Prevents WebSocket disconnect when a file
is moved between glob enumeration and rename.

Subject: [PATCH 45/57] Add documentation wiki system (Phase 9)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Infrastructure:
- CLAUDE.md at ccweb root with wiki update reminder (persists across
  commits — "when you change any feature, update the corresponding doc")
- Backend: GET /api/docs (tree with frontmatter), GET /api/docs/{path}
  (raw markdown, frontmatter stripped), GET /api/docs-search?q= (full
  text search with snippets)
- _parse_frontmatter() helper (simple YAML key:value parser, no deps)
- Path traversal protection on doc content endpoint

Frontend:
- WikiSidebar.tsx: section-grouped navigation tree, live search with
  debounced API calls, active page highlighting
- WikiPage.tsx: markdown rendering with react-markdown + remark-gfm,
  internal link resolution (relative paths navigate within wiki),
  breadcrumb navigation, styled tables and code blocks
- App.tsx routing: wikiPath state toggles between session view and wiki
  view. WikiSidebar replaces SessionSidebar when in wiki mode.
- "Wiki / Help" button at bottom of SessionSidebar

Example docs:
- index.md (home page with section links)
- getting-started/installation.md, quickstart.md
- features/sessions.md, interactive-ui.md
- troubleshooting/common-issues.md
- Existing: architecture/design-plan.md, v2-roadmap.md

All docs use YAML frontmatter (title, description, order) for sidebar
sorting. Internal links use relative paths that work both on GitHub
and in the wiki UI.

+# CLAUDE.md
+
+ccweb — React web gateway to Claude Code sessions via tmux. Replaces the Telegram interface with a browser-based UI.
+
+Tech stack: Python (FastAPI + WebSocket), React (TypeScript + Vite + Tailwind), tmux (libtmux).
+
+## Common Commands
+
+```bash
+# Backend
+cd ccweb && uv run ruff check ccweb/backend/       # Lint
+cd ccweb && uv run ruff format ccweb/backend/       # Format
+cd ccweb && pip install -e .                         # Install backend
+
+# Frontend
+cd ccweb/frontend && npx tsc -b --noEmit            # Type check
+cd ccweb/frontend && npx vite build                  # Production build
+cd ccweb/frontend && npm run dev                     # Dev server (:5173)
+
+# Run
+ccweb                    # Start server (default :8765)
+ccweb install            # Install hook + global commands
+ccweb hook               # SessionStart hook handler
+```
+
+## Documentation Wiki — IMPORTANT
+
+The `docs/` directory contains all user-facing documentation, rendered both as repo-readable markdown AND in the in-app wiki at `/wiki`.
+
+**When you change any feature, endpoint, component, protocol message, configuration option, or user-facing behavior, you MUST update the corresponding doc file in `docs/`.** This is not optional — the wiki is the primary user documentation.
+
+Doc files use YAML frontmatter (`title`, `description`, `order`) for wiki sidebar sorting. Internal links use relative paths (`../features/sessions.md`).
+
+Key doc locations:
+- `docs/getting-started/` — installation, setup, quickstart
+- `docs/configuration/` — env vars, preferences
+- `docs/features/` — one file per feature
+- `docs/architecture/` — system design, protocol reference
+- `docs/troubleshooting/` — common issues, debugging
+
+## Architecture
+
+- Backend: `ccweb/backend/` — FastAPI server, WebSocket handler, session management
+- Core modules: `ccweb/backend/core/` — forked from ccbot (tmux_manager, session_monitor, terminal_parser, etc.)
+- Frontend: `frontend/src/` — React components, hooks, protocol types
+- State: `~/.ccweb/` — state.json, session_map.json, monitor_state.json, preferences.json
+- Docs: `docs/` — markdown wiki files
+
+## Key Design Constraints
+
+- **Single user** — no multi-user auth
+- **File-based decision grids** — skills write JSON to `.ccweb/pending/`, backend polls, AskUserQuestion blocks Claude
+- **WebSocket protocol** — all real-time comms via typed JSON messages (see `ws_protocol.py` / `protocol.ts`)
+- **Forked modules** — core/ modules are forks from ccbot with import paths adapted; `~/.ccweb/` state is fully separate from `~/.ccbot/`

+description: Handling Claude Code prompts — permissions, questions, plan mode
+order: 2
+---
+
+# Interactive UI
+
+When Claude Code displays an interactive prompt (AskUserQuestion, permission request, plan mode), CCWeb renders it as clickable HTML components instead of requiring terminal keyboard navigation.
+
+## AskUserQuestion
+
+Rendered as clickable option cards. Click an option to select it, then click **Submit**.
+
+## Permission Prompts
+
+Rendered as **Allow** / **Deny** buttons with the action description shown. For bash commands, the command is displayed in a code block.
+
+## Plan Mode (ExitPlanMode)
+
+Rendered as **Proceed** / **Edit Plan** buttons with the plan summary displayed as text.
+
+## Fallback
+
+If CCWeb can't parse the terminal UI into structured data (e.g., a new Claude Code UI format), it falls back to displaying the raw terminal text with generic navigation buttons (Space, Up, Down, Enter, Escape, Tab).
+
+## Stale UI Guard
+
+If you click a button after the prompt has already been dismissed (e.g., Claude timed out), CCWeb detects this and shows "This prompt has expired" instead of sending a blind keystroke.

+
+# Sessions
+
+Each session is a Claude Code instance running in a tmux window, bound to a project directory.
+
+## Creating a Session
+
+1. Click **+ New** in the sidebar or press **Ctrl+N**
+2. Browse to your project directory using the file tree
+3. Optionally enter a session name
+4. Click **Create Session**
+
+The session appears in the sidebar and is auto-selected.
+
+## Switching Sessions
+
+Click any session in the sidebar to switch to it. The message stream loads that session's history.
+
+## Killing a Session
+
+Click the **x** button on a session in the sidebar. This kills the tmux window and the Claude Code process in it.
+
+## Session Status
+
+Sessions show their working directory below the name. The sidebar updates in real-time as sessions are created or killed.
+
+## Health Warnings
+
+If tmux is not running or the SessionStart hook is not installed, warning banners appear at the top of the sidebar with instructions to fix the issue.

+
+## 1. Create a Session
+
+Click **+ New** in the sidebar, or press **Ctrl+N**. The directory picker opens — browse to your project folder and click **Create Session**.
+
+Claude Code launches in a new tmux window for that directory.
+
+## 2. Send a Message
+
+Type in the message input area at the bottom. Press **Ctrl+Enter** or click **Send** to submit.
+
+Claude's responses appear in the message stream with markdown rendering.
+
+## 3. Use Commands
+
+Type `/` to open the command palette, or click the **/ Commands** button. Built-in commands like `/clear`, `/compact`, `/model` are available, plus any project-specific commands from `.claude/commands/`.
+
+## 4. Interactive Prompts
+
+When Claude asks a question (AskUserQuestion, permission prompts, plan mode), clickable buttons appear instead of terminal navigation. Click to respond.
+
+## 5. Keyboard Shortcuts
+
+| Shortcut | Action |
+|----------|--------|
+| Ctrl+Enter | Send message |
+| Ctrl+N | New session |
+| Ctrl+Up/Down | Command history |
+| Esc button | Interrupt Claude |

+
+# Common Issues
+
+## "tmux is not running"
+
+Start a tmux session before running CCWeb:
+
+```bash
+tmux new -s ccbot
+```
+
+## Sessions not appearing
+
+Make sure the SessionStart hook is installed:
+
+```bash
+ccweb install
+```
+
+Check `~/.claude/settings.json` has a `SessionStart` hook entry pointing to `ccweb hook`.
+
+## WebSocket disconnected
+
+The connection status indicator in the bottom bar shows the current state. CCWeb auto-reconnects with exponential backoff. If it stays disconnected, check that the backend is running.
+
+## No messages appearing
+
+Messages are delivered via JSONL polling (2-second interval). If messages don't appear:
+
+1. Check the session is bound correctly (click it in the sidebar)
+2. Check the hook wrote to `~/.ccweb/session_map.json`
+3. Check Claude Code is actually running in the tmux window
+
+## File upload fails
+
+Ensure the session has a known working directory (the hook must have fired). The file is saved to `{cwd}/docs/inbox/` in the session's project.

Subject: [PATCH 46/57] Fix path traversal guard and file read race in docs
 endpoint

- Replace str.startswith() with Path.is_relative_to() for path
  traversal check (prevents prefix attack on sibling directories)
- Replace exists() + read_text() with try/except to handle race
  condition where file is deleted between check and read
- Catches FileNotFoundError, IsADirectoryError, and generic OSError

Subject: [PATCH 48/57] Add responsive design for tablet (Phase 10)

Layout:
- Desktop (>1024px): sidebar visible alongside content (unchanged)
- Tablet (<=1024px): sidebar becomes a slide-out drawer with hamburger
  button, backdrop overlay to close

New hook:
- useResponsive.ts: detects tablet breakpoint via matchMedia listener

App.tsx changes:
- Sidebar wrapped in positioned container with CSS transition
- Hamburger button (fixed top-left, 44x44px touch target)
- Backdrop closes drawer on tap
- Session selection auto-closes drawer on tablet
- Main content area gets top padding for hamburger on tablet

CSS additions:
- @media (max-width: 1024px) enforces 44px min button/touch sizes
- font-size: 16px on textarea to prevent iOS auto-zoom
- -webkit-fill-available for virtual keyboard push-up

Subject: [PATCH 49/57] Hide hamburger button when modal overlays are open

On tablet, the hamburger button (z-index 200) was visible and
clickable above DecisionGrid and DirectoryPicker modals (z-index 100),
allowing the sidebar drawer to open behind a modal. Now the hamburger
is hidden when showDirectoryPicker or decisionGrid is active.

Subject: [PATCH 50/57] Fill all plan gaps before Phase 11
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend gaps filled:
- REST POST /api/sessions and DELETE /api/sessions/{window_id} endpoints
  (plan called for both REST and WebSocket — WebSocket-only before)
- POST /api/sessions/{window_id}/setup-ccweb: creates .ccweb/instructions.md
- Stale grid file cleanup: files >1hr in pending/ moved to failed/
- Auto-create .ccweb/pending/ directory on session creation (both REST
  and WebSocket create_session paths)

Frontend gaps filled:
- localStorage persistence: recent directories (DirectoryPicker shows
  last 5 used paths), message filter state, last active session
- Swipe gestures: swipe right from left edge opens sidebar drawer,
  swipe left closes it (tablet only)
- Ctrl+K keyboard shortcut toggles command palette via
  externalPaletteToggle prop

Subject: [PATCH 51/57] Fix localStorage crash and StrictMode palette toggle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Wrap addRecentDir localStorage.setItem in try/catch (was the only
  unguarded localStorage call — would crash handleConfirm if storage
  unavailable, preventing session creation)
- Change Ctrl+K palette toggle from boolean to counter so React
  StrictMode double-invocation doesn't cancel the toggle. Effect now
  sets palette to true (idempotent) instead of toggling.

Subject: [PATCH 52/57] Fix session restore, reconnect, and stale DecisionGrid

- Auto-send switch_session when WebSocket connects/reconnects and there
  is an active session (restored from localStorage or currently selected).
  Fixes: empty message stream on page reload, and silent message loss
  after WebSocket reconnection.
- Clear all session state (including DecisionGrid) when killing the
  active session. Fixes: stale DecisionGrid overlay lingering after
  its session is killed.

Subject: [PATCH 54/57] Fix browse containment, session_map wipe, and double
 switch_session

Backend:
- /api/browse now enforces containment within browse_root (defaults to
  home dir). Prevents arbitrary filesystem directory enumeration.
  Parent nav stops at the root boundary.
- load_session_map skips stale cleanup when valid_wids is empty,
  preventing total window_states wipe during transient session_map
  reads (mid-write race or mismatched tmux session name)

Frontend:
- switch_session useEffect only fires on status transition TO
  "connected" (using prevStatusRef), not on every activeWindowId
  change. Prevents double switch_session (and duplicate history
  load / potential message loss) on manual session selection.

When the server broadcasts an updated sessions list that no longer
includes the currently active window_id, clear the active session
state (messages, status, interactive UI, decision grid) and remove
from localStorage. Prevents the user from interacting with a phantom
session that was killed by another client or externally.

Subject: [PATCH 56/57] Add Phase 11 QoL features: notifications, rename,
 export, context

Browser notifications (useNotifications.ts):
- Request permission on first visit
- Notify when interactive UI appears and tab is not focused
- Click notification to focus the tab

Session rename:
- Double-click session name in sidebar to edit inline
- PUT /api/sessions/{window_id}/rename backend endpoint
- Updates tmux window name + display name + broadcasts to all clients

Export conversation:
- GET /api/sessions/{window_id}/export?fmt=markdown|json|plain endpoint
- Formats messages as Markdown (with thinking in details tags, tools
  in code blocks), JSON, or plain text
- Export button in StatusBar triggers download

Context/cost indicator:
- Parse "Context: N%" from Claude Code's status bar chrome via regex
- Added context_pct field to WsStatus protocol message
- StatusBar shows colored context percentage (green <50%, yellow
  50-80%, red >80%)
- Clears on session switch

Subject: [PATCH 57/57] Add README.md, deferred items grid, and session history
 docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- README.md: project overview, quick start, architecture diagram,
  links to all documentation, configuration reference, standalone
  repo instructions
- docs/architecture/deferred-items.md: prioritized grid of all 27
  deferred features with effort, usefulness, success probability,
  and reason for deferral. Includes top-5 impact/effort ranking.
- docs/architecture/session-history.md: complete history of the
  build session — origin, all 12 phases, key architectural decisions,
  adversarial review process (40+ bugs found/fixed), what a new
  Claude Code session needs to know to pick up where this left off

+# CCWeb
+
+A browser-based interface for Claude Code sessions running in tmux. Replaces the Telegram bot interface with a richer web experience.
+
+## Features
+
+- **Styled message stream** with markdown rendering, expandable thinking blocks, copy buttons on code
+- **Interactive UI** — AskUserQuestion, permission prompts, plan mode rendered as clickable buttons (not terminal arrow-key navigation)
+- **Decision grids** — batch option selection with notes column, rendered from JSON files written by Claude Code skills
+- **Session management** — create, switch, rename, kill sessions via sidebar with directory picker
+- **Command palette** — `/` auto-complete with built-in commands + project-specific skill discovery
+- **File upload** — drag-and-drop or paperclip button, saved to project's `docs/inbox/`
+- **Message filters** — All / Chat / No Thinking / Tools toggle chips
+- **Browser notifications** — alerts when Claude needs input and tab is unfocused
+- **Context indicator** — shows Claude's context usage percentage with color coding
+- **Export** — download conversation as Markdown, JSON, or plain text
+- **Responsive** — works on desktop Chrome and tablet (Samsung Z Fold 7 tested)
+- **In-app wiki** — documentation rendered from `docs/` markdown files with search
+
+## Quick Start
+
+```bash
+# Install
+pip install -e .
+ccweb install      # Set up SessionStart hook + global slash commands
+
+# Start tmux

+title: Deferred Items
+description: Complete grid of all deferred features with effort, usefulness, and success estimates
+order: 3
+---
+
+# Deferred Items Grid
+
+All features deferred from v1, with estimates for prioritization.
+
+## A. Rich Tool Output Rendering
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 1 | **File diff viewer** — green/red highlighting, collapsible per file | Medium (2-3 days) | **Very High** — most frequent tool output, massive UX win | 95% | Requires custom diff parser component; `<pre>` blocks work for v1 |
+| 2 | **Progress tracker** — TodoWrite as persistent checkbox panel | Medium (1-2 days) | Medium — nice visibility but TodoWrite is used inconsistently | 90% | Needs new pinned panel UI pattern; low priority vs core features |
+| 3 | **Search results cards** — Grep/WebSearch as structured cards | Medium (2 days) | Medium — improves readability of search results | 85% | Requires parsing multiple tool output formats into structured data |
+| 4 | **Destructive action warning** — red-bordered permission prompts | Small (0.5 days) | Medium — safety UX improvement | 98% | Simple keyword detection; deferred because base permission UI works |
+
+## B. Subagent Tracking
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 5 | **Collapsible task cards** — nested agent activity in message stream | Medium (2 days) | High — critical for multi-agent workflows | 90% | Requires indentation/nesting model in message stream; tool_use/result pairing already works flat |
+| 6 | **Subagent status badge** — "2 agents running" indicator | Small (0.5 days) | Medium — quick glance at agent activity | 95% | Depends on #5 for real value |
+| 7 | **Real-time subagent JSONL streaming** — monitor subagent session files | Large (3-5 days) | High — see what agents are doing live, not just final results | 60% | Requires discovering subagent session IDs from parent JSONL, monitoring multiple files dynamically; Claude Code's subagent format may change |
+
+## C. Saved Prompts Library
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 8 | **Prompt Library UI** — fuzzy search, categories, preview | Medium (2-3 days) | High — eliminates copy/paste for repeated prompts | 90% | Full CRUD UI + backend; deferred because command palette covers slash commands |
+| 9 | **Variable placeholders** — `{{filename}}` with fill-in form | Medium (1-2 days) | Medium — power-user feature | 80% | Template parsing + dynamic form generation; nice but not essential |
+| 10 | **Global + project prompts** — `~/.ccweb/prompts/` + `{project}/.ccweb/prompts/` | Small (1 day) | Medium — organization for prompt collections | 95% | File-based storage is simple; deferred because the library UI (#8) is needed first |
+
+## D. Decision Grid v2
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 11 | **Keyboard navigation** — arrow keys between cells, Tab to notes | Small (1 day) | Medium — power-user speed improvement | 95% | Focus management in a grid is fiddly; mouse works fine for v1 |
+| 12 | **Comparison mode** — side-by-side option comparison | Medium (2 days) | Low — rarely need to compare options in detail | 75% | Niche use case; the description field usually provides enough context |
+| 13 | **"Explain this option" button** — ask Claude for elaboration per row | Medium (1-2 days) | Medium — reduces back-and-forth | 70% | Requires sending text to Claude while grid is open, handling the response asynchronously; timing is tricky with AskUserQuestion blocking |
+
+## E. Performance
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 14 | **inotify/watchdog streaming** — replace 2s JSONL polling | Medium (2-3 days) | **Very High** — near-instant responses instead of 2s bursts | 80% | Requires `watchdog` dependency, careful partial-write handling, and testing on WSL (inotify can be unreliable on WSL2 filesystem mounts) |
+
+## F. Creative UX Explorations
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 15 | **Optimistic input** — show user message immediately with pending indicator | Small (0.5 days) | High — feels much more responsive | 95% | Simple state addition; deferred because it's pure polish |
+| 16 | **Message threading** — nest Q&A exchanges (Slack-style) | Large (3-5 days) | Medium — helps in long sessions but changes the core message model | 50% | Fundamental change to message stream rendering; unclear how to detect thread boundaries in Claude's output |
+| 17 | **Session timeline scrubber** — minimap of session phases | Large (3-4 days) | Medium — novel visualization | 60% | Requires phase detection heuristics (thinking vs tool use vs conversation); complex custom UI |
+| 18 | **Live file preview pane** — split view showing file state after Edit | Large (3-5 days) | High — see what the file looks like now, not just the diff | 65% | Requires reading files from the project directory via a new API; security implications of serving arbitrary file content |
+| 19 | **Pinned messages** — pin key decisions to session top | Medium (1-2 days) | Medium — useful for long sessions | 85% | Needs persistent pin state (per-session localStorage or backend); simple UI but needs thought on what "pinning" means |
+| 20 | **Session heatmap** — activity timeline + token spend per session | Medium (2 days) | Low — analytics/insight feature | 70% | Requires tracking activity timestamps and token data that may not be in JSONL |
+| 21 | **Quick reactions on tool results** — thumbs-up/flag | Small (1 day) | Low — feedback signal with no immediate use | 80% | Needs storage for reactions; unclear what value they provide without a feedback loop |
+| 22 | **Minimap** — VS Code-style vertical scroll overview | Large (3-4 days) | Low-Medium — scroll orientation aid | 50% | Complex canvas/SVG rendering; high effort for modest value |
+| 23 | **Keyboard-first navigation** — Linear-style G+S, G+P shortcuts | Small (1 day) | Medium — power-user productivity | 90% | Simple key handler additions; deferred because mouse/touch works |
+| 24 | **Stackable message filters** — combine filters (chat + tools) | Small (0.5 days) | Medium — more granular filtering | 95% | Change filter from single enum to bitfield; simple but the current 4 presets cover most needs |
+
+## G. UI Polish
+
+| # | Item | Effort | Usefulness | Success | Reason Deferred |
+|---|------|--------|------------|---------|-----------------|
+| 25 | **Dark/light theme toggle** | Medium (1-2 days) | Medium — accessibility and preference | 90% | CSS variable swap; needs a second set of color values and a preferences persistence mechanism |
+| 26 | **Notification badges on sessions** — unread indicator | Small (1 day) | High — know which sessions have new activity | 90% | Track last-read offset per session in frontend; show badge when messages arrive for non-active session |
+| 27 | **Per-project setup banner** — "Enable CCWeb features?" on first session | Small (0.5 days) | Low — one-time convenience | 95% | Check for `.ccweb/instructions.md` existence; show dismissable banner |
+
+## Top 5 by Impact/Effort Ratio
+
+If picking what to build next:
+
+1. **#15 Optimistic input** — 0.5 days, high usefulness, 95% success
+2. **#26 Notification badges** — 1 day, high usefulness, 90% success
+3. **#4 Destructive action warning** — 0.5 days, medium usefulness, 98% success
+4. **#1 File diff viewer** — 2-3 days, very high usefulness, 95% success
+5. **#14 inotify streaming** — 2-3 days, very high usefulness, 80% success (WSL risk)

+
+# Build Session History
+
+This document captures the history of the original Claude Code session that built CCWeb, so a new session can pick up where we left off with full context.
+
+## Origin
+
+CCWeb was designed as a replacement for CCBot's Telegram interface. The user wanted a richer browser-based experience for interacting with Claude Code sessions running in tmux, specifically:
+- A styled message stream instead of raw terminal output
+- Clickable interactive UI (instead of terminal arrow-key navigation)
+- A decision grid system for batch choices
+- Session management similar to Telegram topics
+
+The existing CCBot codebase at `/home/user/ccbot-workshop/src/ccbot/` was used as a reference. Seven core modules were **forked** (not copied verbatim — all needed import path changes) into `ccweb/ccweb/backend/core/`.
+
+## Build Phases Completed
+
+All 12 phases from the design plan are complete:
+
+| Phase | What | Status |
+|-------|------|--------|
+| 1 | Backend scaffold (FastAPI, WebSocket, forked core modules) | Done |
+| 2 | React frontend scaffold (Vite, TypeScript, Tailwind) | Done |
+| 3 | Message stream, file upload, text input, status bar | Done |
+| 4 | Session management (sidebar, directory picker with file tree) | Done |
+| 5 | Interactive UI (AskUserQuestion, permissions, plan mode as buttons) | Done |
+| 6 | Decision grid (file-based detection, AskUserQuestion blocking) | Done |
+| 7 | Command palette (/ auto-complete, skill discovery, dropdown) | Done |
+| 8 | Message filters (All/Chat/No Thinking/Tools) | Done |
+| 9 | Documentation wiki (in-app rendering of docs/ markdown) | Done |
+| 10 | Responsive design (tablet drawer, swipe, touch targets) | Done |
+| 11 | QoL (notifications, context %, rename, export, persistence) | Done |
+| 12 | Polish (auto-scroll, expandable blocks, images, reconnect, shortcuts) | Done |
+
+## Key Architectural Decisions
+
+1. **Forked modules, not shared package**: Core modules (`tmux_manager`, `session_monitor`, `terminal_parser`, etc.) were copied and adapted from ccbot, not imported. This ensures ccweb is self-contained and can be a standalone repo. All use `~/.ccweb/` for state (not `~/.ccbot/`).
+
+2. **File-based decision grids**: The original plan used text markers (`<!--ccweb:grid {json}-->`) in Claude's output. Adversarial review identified this as fragile (LLM output is unreliable). Changed to file-based: Claude writes JSON to `.ccweb/pending/`, backend polls the directory. The skill MUST call `AskUserQuestion` after writing the file to block Claude until the user responds.
+
+3. **Single user, single browser session**: No multi-user auth. WebSocket client_bindings are ephemeral. Interactive UI responses are last-click-wins.
+
+4. **Per-project instructions via `.ccweb/instructions.md`**: Instead of mutating CLAUDE.md (causes git noise), ccweb creates a separate file that CLAUDE.md can reference. Can be .gitignored.
+
+5. **Separate state directories**: ccbot uses `~/.ccbot/`, ccweb uses `~/.ccweb/`. Both can coexist monitoring the same tmux sessions. The SessionStart hook must be `ccweb hook` (writes to `~/.ccweb/session_map.json`).
+
+## Adversarial Review Process
+
+The codebase went through **multiple rounds of three-agent adversarial code review**. Each round used three independent agents (backend, frontend, integration) that read the actual code from scratch with no context from previous rounds. Reviews continued until all three agents passed clean simultaneously.
+
+### Total bugs found and fixed across all review rounds: 40+
+
+Key categories of bugs caught:
+- **Missing dependency**: `python-multipart` not in pyproject.toml (app wouldn't start)
+- **Package structure**: wrong `packages` path in pyproject.toml (empty wheel)
+- **Security**: path traversal in file upload (filename with `../`), browse endpoint without containment
+- **Protocol gaps**: decision_grid handler missing in frontend, dead WsReplay code
+- **Race conditions**: grid file rename during concurrent access, double switch_session, stale closures
+- **State management**: phantom WindowState entries, session_map wipe on empty valid_wids, externally killed session leaving stale UI
+- **UX**: hamburger button z-index above modals, CommandPalette Enter interception, StrictMode toggle
+
+## What a New Session Needs to Know
+
+### To run the project
+```bash
+# Backend
+cd ccweb
+pip install -e .
+ccweb install    # Install hook + global commands
+ccweb            # Start server on :8765
+
+# Frontend (dev)
+cd ccweb/frontend
+npm install
+npm run dev      # Vite dev server on :5173 (proxies to :8765)
+```
+
+### To make changes
+- Backend Python: `ccweb/ccweb/backend/` — run `uv run ruff check` and `ruff format`
+- Frontend TypeScript: `ccweb/frontend/src/` — run `npx tsc -b --noEmit` and `npx vite build`
+- **When changing any feature, update the corresponding doc in `docs/`** (see CLAUDE.md)
+
+### Key files
+- `ccweb/CLAUDE.md` — project instructions for Claude Code
+- `docs/architecture/design-plan.md` — the full design plan with all decisions
+- `docs/architecture/v2-roadmap.md` — deferred features by category
+- `docs/architecture/deferred-items.md` — prioritized grid with effort/usefulness estimates
+- `ccweb/ccweb/backend/server.py` — the main FastAPI server (largest file, ~850 lines)
+- `ccweb/ccweb/backend/ws_protocol.py` — all WebSocket message type definitions
+- `ccweb/frontend/src/protocol.ts` — TypeScript mirror of ws_protocol.py
+- `ccweb/frontend/src/App.tsx` — main React component (wires everything together)
+- `ccweb/frontend/src/hooks/useSession.ts` — session state management
+- `ccweb/frontend/src/hooks/useWebSocket.ts` — WebSocket connection + reconnect
+
+### Known limitations
+- **2-second message latency**: JSONL polling interval. inotify streaming is item #14 in deferred items.
+- **No streaming**: Messages appear in bursts, not token-by-token. Status bar provides "working" feedback.
+- **Fragile interactive UI parsing**: `ui_parser.py` screen-scrapes terminal text for checkbox markers. Falls back to raw text if parsing fails. Will break if Claude Code changes its UI format.
+- **Tool output is `<pre>` blocks**: No rich diff viewer, search cards, or progress tracker yet (deferred items #1-4).
+
+### Things that are NOT bugs (came up in reviews)
+- `ccbot` in tmux session name references is intentional (shared tmux session)
+- Infinite WebSocket reconnect (no "disconnected" terminal state) is by design
+- `user_window_offsets` in session.py is dead code (never read/written) — harmless
+- Module-level `msgCounter` in useSession.ts grows monotonically — intentional for unique React keys
