- Add acquire_lock/release_lock to prevent daemon vs manual conflicts
- Check cmd_start/cmd_continue success before updating state to 'notified'
- Set state to 'error' if command fails
- Track actual session_id from session file after cmd_start completes
- Release lock when task completes (success or error)
- Use load_agent_env 'pm-agent' for GITEA_TOKEN

+# Fix: Queue daemon spawning excess agents due to race condition
+
+## Problem
+
+When enqueueing multiple tasks (e.g., 6 tasks), the queue daemon was spawning many more subagents than expected, eventually exhausting container memory.
+
+**Root Cause:** The combination of:
+1. `process_queue()` calling `opencode run` directly instead of `kugetsu start`, bypassing all concurrency logic
+2. `count_active_dev_sessions()` counting `pm-agent.json` toward `MAX_CONCURRENT_AGENTS`, reducing effective dev agent slots
+3. No atomic locking around session count check + session file creation (TOCTOU race condition)
+4. Background spawning of multiple concurrent processes in `process_queue()`
+
+**Expected behavior:** With `MAX_CONCURRENT_AGENTS=3` and 6 tasks:
+- Tasks should be processed sequentially via `kugetsu start`
+- Only 3 dev agents should run at a time
+- Tasks should queue and wait for slots to free up
+
+## Solution
+
+### 1. `count_active_dev_sessions()` - Exclude pm-agent
+Only count actual dev agent session files (exclude `pm-agent.json`).
+
+### 2. `process_queue()` - Call `kugetsu start` directly + retry logic
+- Call `kugetsu start` directly (foreground, sequential) instead of spawning `opencode run` background process
+- Dynamic batch size = available slots (removes need for `QUEUE_DAEMON_BATCH_SIZE`)
+- Retry logic (max 3 attempts) on failure
+- On failure: cleanup worktree/session and revert to `pending` state
+- Save `fork_pid` to queue item for timeout handling
+
+### 3. `cmd_start()` - Add flock
+- Add flock around critical section (count check + fork)
+- Track `fork_pid` for queue item timeout handling
+
+### 4. Notification System
+New notification types:
+| Event | Type |
+|-------|------|
+| Task enqueued | `task_queued` |
+| Task dequeued | `task_dequeued` |
+| Task started | `task_started` |
+| Task completed | `task_completed` |
+| Task error | `task_error` |
+
+### 5. Config
+- Remove `QUEUE_DAEMON_BATCH_SIZE` (no longer needed - batch size is now dynamic)
+
+## Notification Flow
+
+| Event | Location | Type |
+|-------|----------|------|
+| Task enqueued | `enqueue_task()` | `task_queued` |
+| Task dequeued | `process_queue()` after state change to `notified` | `task_dequeued` |
+| Task started | `cmd_start()` after session file created | `task_started` |
+| Task completed | `update_queue_item_state()` | `task_completed` |
+| Task error | `update_queue_item_state()` | `task_error` |
+
+## Out of Scope
+
+- Re-check loop in cmd_start (checking if session DB is reliable) - deferred to separate research issue
+- Buffer mechanism for excess forking (safety failsafe only)

+# Versioning Policy
+
+## Branch Strategy
+
+Kugetsu uses a dual-branch model:
+
+| Branch | Purpose | Version | Stability |
+|--------|---------|---------|-----------|
+| `main` | Stable releases | 0.1.x | Production-ready |
+| `develop` | Experimental work | 0.2.x | Active development |
+
+### Branch Definitions
+
+- **`main`**: Contains the latest stable 0.1.x releases. All changes here should be production-ready and backport-compatible when possible.
+
+- **`develop`**: Contains work for the next major version (0.2.x). This branch may contain experimental features that could change or be removed.
+
+## Version Format
+
+Versions follow [Semantic Versioning](https://semver.org/):
+```
+MAJOR.MINOR.PATCH
+```
+
+- **MAJOR**: Incompatible API/behavior changes
+- **MINOR**: New functionality (backward-compatible)
+- **PATCH**: Bug fixes (backward-compatible)
+
+## Backport Compatibility
+
+### Backport-Compatible Changes (0.1.x)
+- Bug fixes
+- Documentation updates
+- Performance improvements
+- Adding new inputs/options (must have sensible defaults)
+- Changes that only affect 0.2.x-specific features
+
+### NOT Backport-Compatible
+- Removing or renaming existing options
+- Changing default values of existing options
+- Changing behavior of existing commands
+- Introducing breaking changes to the API/shell interface
+
+## Deprecation Policy
+
+When introducing breaking changes:
+
+1. **Deprecate in minor X**: Add warning messages, document the change
+2. **Remove in major X+1**: The breaking change is removed in the next major version
+
+Example:
+- Option `--old-flag` deprecated in v0.1.5
+- Option `--old-flag` removed in v1.0.0 (not v0.2.0)
+
+## What Constitutes a Version Bump
+
+| Change Type | Version Bump |
+|-------------|--------------|
+| Add new command/option | MINOR |
+| Bug fix | PATCH |
+| Change default value | MINOR (may warrant PATCH) |
+| Add new required input | MAJOR |
+| Remove deprecated feature | MAJOR |
+| Change behavior of existing command | MINOR (needs deprecation first) |
+
+## Release Process
+
+1. Changes are developed on feature branches
+2. PRs are opened against `main` for 0.1.x changes, or `develop` for 0.2.x
+3. After review and approval, changes are squash-merged
+4. Releases are tagged from `main` after significant changes

+# OpenCode Session Internals
+
+This document contains findings about how OpenCode manages sessions, based on direct database investigation. Use this when debugging session-related issues in kugetsu.
+
+## Database Location
+
+```bash
+opencode db path
+# Returns: ~/.local/share/opencode/opencode.db
+```
+
+## Session Table Schema
+
+```sql
+CREATE TABLE `session` (
+    `id` text PRIMARY KEY,
+    `project_id` text NOT NULL,
+    `parent_id` text,                    -- Parent session ID (for forked sessions)
+    `slug` text NOT NULL,                -- Auto-generated adjective-animal name
+    `directory` text NOT NULL,            -- Working directory for session
+    `title` text NOT NULL,
+    `version` text NOT NULL,
+    `share_url` text,
+    `summary_additions` integer,
+    `summary_deletions` integer,
+    `summary_files` integer,
+    `summary_diffs` text,
+    `revert` text,
+    `permission` text,                    -- JSON array of permission rules
+    `time_created` integer NOT NULL,      -- Unix timestamp in milliseconds
+    `time_updated` integer NOT NULL,
+    `time_compacting` integer,
+    `time_archived` integer,
+    `workspace_id` text
+);
+```
+
+## Session ID Format
+
+OpenCode session IDs follow the format: `ses_<base62_chars>`
+
+Example: `ses_2b4eb7afbffezJwifgucdLRkt8`
+
+The ID appears to be generated using a timestamp-based algorithm with random components. Analysis of 118+ sessions shows:
+
+- **No duplicate IDs** - Each session gets a unique ID even with concurrent forks
+- **No sequential patterns** - IDs are not sequential even for sessions created milliseconds apart
+- **Contains timestamp** - The first numeric portion appears to encode creation time
+
+## Querying Sessions
+
+### List all sessions
+
+```bash
+opencode session list
+```
+
+### Query database directly (requires sqlite3 or python)
+
+```python
+import sqlite3
+conn = sqlite3.connect('/home/shoko/.local/share/opencode/opencode.db')
+cursor = conn.cursor()
+
+# Get all sessions
+cursor.execute('SELECT id, parent_id, slug, directory FROM session')
+
+# Get forked sessions (sessions with a parent)
+cursor.execute('SELECT id, parent_id FROM session WHERE parent_id IS NOT NULL')
+
+# Get sessions by directory
+cursor.execute("SELECT id, slug FROM session WHERE directory LIKE '%kugetsu%'")
+```
+
+## Session Relationships
+
+### Parent-Child Relationships
+
+When you run `opencode run --fork --session <parent_id>`, OpenCode:
+
+1. Creates a NEW session with a unique ID
+2. Sets the `parent_id` field to reference the parent session
+3. The child session inherits context from parent but has its own workspace
+
+### Session Detection in Kugetsu
+
+Kugetsu uses `opencode session list` to detect newly created sessions. The output format is:
+
+```
+ses_abc123def456
+ses_xyz789...
+```
+
+Kugetsu's `cmd_start` workflow:
+
+1. **Before fork**: List all sessions, store in array
+2. **Fork**: Run `opencode run --fork --session <parent>`
+3. **After fork**: List sessions again
+4. **Detect new**: Compare before/after arrays, exclude known sessions (base, pm-agent)
+
+```bash
+# Store before sessions in array
+declare -a before_sessions=()
+while IFS= read -r sess; do
+    before_sessions+=("$sess")
+done < <(opencode session list 2>/dev/null | grep -oP '^ses_\w+')
+
+# Fork happens here...
+
+# Find sessions not in before array
+while IFS= read -r sess; do
+    # Skip base and pm-agent sessions
+    [ "$sess" = "$base_session_id"" ] && continue
+    [ "$sess" = "$pm_agent_session_id" ] && continue
+    
+    # Check if session existed before
+    local existed_before=false
+    for before_sess in "${before_sessions[@]}"; do
+        if [ "$sess" = "$before_sess" ]; then
+            existed_before=true
+            break
+        fi
+    done
+    
+    if [ "$existed_before" = false ]; then
+        new_session_id="$sess"
+        break
+    fi
+done < <(opencode session list 2>/dev/null | grep -oP '^ses_\w+')
+```
+
+## Session Directories
+
+Each session has a `directory` field indicating its working directory:
+
+| Directory | Purpose |
+|-----------|---------|
+| `/home/shoko` | Base session, PM agent |
+| `/home/shoko/repositories/kugetsu` | Project sessions |
+| `~/.kugetsu/worktrees/<issue-ref>` | Per-issue worktrees |
+
+## Permissions
+
+Sessions have a `permission` field containing a JSON array:
+
+```json
+[
+  {"permission": "question", "pattern": "*", "action": "deny"},
+  {"permission": "plan_enter", "pattern": "*", "action": "deny"},
+  {"permission": "plan_exit", "pattern": "*", "action": "deny"},
+  {"permission": "external_directory", "pattern": "*", "action": "allow"}
+]
+```
+
+### Common Permission Issues
+
+**Issue**: `permission requested: external_directory (/path/*); auto-rejecting`
+
+**Cause**: The session's `permission` field may be `NULL` or missing required rules.
+
+**Fix**: Update via SQLite:
+
+```python
+import sqlite3
+conn = sqlite3.connect('/home/shoko/.local/share/opencode/opencode.db')
+cursor = conn.cursor()
+
+PERMISSION_JSON = '[{"permission":"question","pattern":"*","action":"deny"},{"permission":"plan_enter","pattern":"*","action":"deny"},{"permission":"plan_exit","pattern":"*","action":"deny"},{"permission":"external_directory","pattern":"*","action":"allow"}]'
+
+cursor.execute("UPDATE session SET permission = ? WHERE id = ?", 
+               (PERMISSION_JSON, session_id))
+conn.commit()
+```
+
+## Known Issues & Solutions
+
+### Session ID Collision (Issue #81)
+
+**Problem**: Forked sessions showing same ID as PM agent.
+
+**Investigation Results**: 
+- OpenCode does NOT generate duplicate IDs (verified with 118+ sessions)
+- Database shows unique IDs even for concurrent forks
+- Issue is in kugetsu's session detection logic, not opencode
+
+**Solution**: Use array-based session detection (see above) instead of string/regex matching.
+
+### Stale Permission NULL (Issue #36)
+
+**Problem**: PM agent cannot access directories despite permissions.
+
+**Root Cause**: Session created with `permission = NULL` in database.
+
+**Detection**:
+```python
+cursor.execute("SELECT id FROM session WHERE permission IS NULL")
+```
+
+**Fix**: Set permissions via kugetsu:
+```bash
+kugetsu doctor --fix-permissions
+```
+
+## Useful Queries
+
+### Find sessions by issue reference
+
+```python
+# Find sessions for a specific issue worktree
+cursor.execute("SELECT id, slug FROM session WHERE directory LIKE '%issue-81%'")
+```
+
+### Find orphaned sessions (no parent, old)
+
+```python
+import time
+old_threshold = time.time() - (30 * 24 * 60 * 60)  # 30 days ago
+
+cursor.execute("""SELECT id, slug, directory, time_created 
+                 FROM session 
+                 WHERE parent_id IS NULL 
+                 AND time_created < ?
+                 ORDER BY time_created""", (old_threshold * 1000,))
+```
+
+### Count sessions per project
+
+```python
+cursor.execute("""SELECT project_id, COUNT(*) as cnt 
+                 FROM session 
+                 GROUP BY project_id 
+                 ORDER BY cnt DESC""")
+```
+
+## Debugging Tips
+
+1. **Check current sessions**: `opencode session list`
+2. **Check database**: `opencode db "SELECT id, parent_id, slug FROM session ORDER BY time_created DESC LIMIT 10"`
+3. **Verify permissions**: Check if `permission` field is NULL or valid JSON
+4. **Check directory**: Ensure session directory exists and is accessible
+5. **Compare before/after**: When debugging detection, log both before and after session lists

+## Configuration
+
+User overrides can be set in `~/.kugetsu/config`. This file is sourced on each kugetsu command call, so changes take effect immediately without re-initialization.
+
+A default config file is created during `kugetsu init` with commented examples:
+
+```bash
+# User configuration overrides
+# Values set here take precedence over defaults
+# Changes take effect immediately (no re-init needed)
+
+# Max concurrent dev agents (default: 3)
+# MAX_CONCURRENT_AGENTS=5
+```
+
+### Available Config Options
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `MAX_CONCURRENT_AGENTS` | 3 | Maximum number of concurrent dev agents |
+| `KUGETSU_TEMP_DIR` | `~/.local/share/opencode/tool-output` | Temp directory for subagent tool output (useful in headless environments where /tmp is restricted) |
+| `KUGETSU_VERBOSITY` | `default` | PM agent verbosity level: `verbose`, `default`, or `quiet` |
+| `QUEUE_DAEMON_INTERVAL_MINUTES` | 5 | How often daemon polls queue (in minutes) |
+| `QUEUE_CLEANUP_AGE_DAYS` | 7 | Auto-cleanup completed/error items older than N days |
+
+### Environment Variables for Agents
+
+Agents receive environment variables through env files, not command-line injection. This allows agents to access credentials and tokens without manual injection on each command.
+
+**Files created during `kugetsu init`:**
+- `~/.kugetsu/env/default.env` - Variables for all agents
+- `~/.kugetsu/env/pm-agent.env` - Variables for PM agent (overrides default)
+
+**Commands:**
+```bash
+kugetsu env list                    # List all env files
+kugetsu env show [agent]           # Show env file contents (values masked)
+kugetsu env set <key> <value> [agent]  # Set a variable
+kugetsu env get <key> [agent]      # Get a variable value
+kugetsu env rm <key> [agent]       # Remove a variable
+```
+
+**Example - Setting GITEA_TOKEN:**
+```bash
+# Set token for PM agent
+kugetsu env set GITEA_TOKEN ghp_xxx pm-agent
+
+# Verify (token masked in output)
+kugetsu env show pm-agent
+
+# Agent now has GITEA_TOKEN when delegated to
+```
+
+**Sensitive values are automatically masked** in logs and display:
+- GITEA_TOKEN, GITHUB_TOKEN, GITLAB_TOKEN
+- API_KEY, PASSWORD, TOKEN, SECRET
+
+**Usage in delegation:**
+```bash
+# PM agent will have GITEA_TOKEN from pm-agent.env
+kugetsu delegate "post comment on #69"
+```

 **Note**: Destroying base also destroys PM agent since PM depends on base.
 
+### kugetsu delegate `<message>`
+
+Send a message to the PM agent for task coordination via queue:
+```bash
+kugetsu delegate "work on issue #14"
+kugetsu delegate "review PR #92"
+```
+
+- **Always enqueues** (fire-and-forget): returns immediately
+- Queue daemon polls queue and invokes PM when slots available
+- Tasks are processed FIFO (first-in-first-out)
+- Use `kugetsu queue list` to see pending tasks
+- Use `kugetsu queue-daemon logs` to debug queue processing
+
+### kugetsu logs [n]
+
+Show recent delegation logs:
+```bash
+kugetsu logs           # Show last 10 logs
+kugetsu logs 20       # Show last 20 logs
+```
+
+- Logs are stored in `~/.kugetsu/logs/`
+- Automatically deletes logs older than 7 days
+
+### kugetsu status
+
+Check if kugetsu is properly initialized:
+```bash
+kugetsu status
+```
+
+Output:
+- `kugetsu_not_initialized` - No index file
+- `base_session_missing` - Base session not found
+- `pm_agent_missing` - PM agent not found
+- `ok` - Everything is initialized
+
+### kugetsu doctor [--fix]
+
+Diagnose and fix kugetsu issues:
+```bash
+kugetsu doctor              # Show diagnostic info
+kugetsu doctor --fix        # Attempt automatic repairs
+```
+
+- Checks index file existence
+- Validates base and PM agent sessions
+- With `--fix`: recreates PM agent if missing
+- With `--fix-permissions`: fixes session permissions in opencode database
+
+### kugetsu notify [list|clear]
+
+Show or clear notifications from PM agent:
+```bash
+kugetsu notify list         # Show unread notifications (default)
+kugetsu notify clear       # Mark all as read
+```
+
+- PM agent writes task completion notifications to `~/.kugetsu/notifications.json`
+- Shows timestamp, type, message, and issue ref for each notification
+
+### kugetsu server <list|add|remove|default|get>
+
+Manage git server configurations:
+```bash
+kugetsu server list              # List all configured servers
+kugetsu server add github https://github.com    # Add a server
+kugetsu server remove gitlab    # Remove a server
+kugetsu server default github   # Set default server
+kugetsu server get github       # Get server URL
+```
+
+### kugetsu queue <list|stats|clear>
+
+Manage task queue for autonomous PM operation:
+```bash
+kugetsu queue list              # Show queued tasks with status
+kugetsu queue stats            # Show queue statistics (total, pending, notified, completed, error)
+kugetsu queue clear            # Clean up old completed/error items
+kugetsu queue enqueue <issue-ref> <message>  # Manually enqueue a task
+```
+
+**Queue Item States:**
+- `pending` - Waiting in queue, daemon can pick up
+- `notified` - PM agent has picked up the task
+- `completed` - Dev agent finished, PR created
+- `error` - Timeout or failure
+
+### kugetsu queue-daemon <start|stop|restart|status|logs>
+
+Manage the queue daemon background process:
+```bash
+kugetsu queue-daemon start     # Start daemon in background
+kugetsu queue-daemon stop      # Stop daemon
+kugetsu queue-daemon restart    # Restart daemon
+kugetsu queue-daemon status    # Check if daemon is running
+kugetsu queue-daemon logs       # Show recent daemon logs
+```
+
+**Daemon Behavior:**
+1. Runs at configurable interval (default: 5 minutes)
+2. Checks if active agents < MAX_CONCURRENT_AGENTS
+3. Picks 1-N pending items (configurable batch size)
+4. Forks PM session for each picked item
+5. PM decides whether to use `start` or `continue`
+
+**Queue Directory:**
+```
+~/.kugetsu/queue/
+├── items/                     # Queue item JSON files
+│   ├── q_1234567890.json    # One file per queued task

-# Creates: worktree at ~/.kugetsu/worktrees/github.com-shoko-kugetsu-14/
+```
 
-# Continue later
+### Normal Workflow
+```bash
