Merge pull request '[FIX] process_queue: add missing closing parentheses' (#143) from fix/issue-142-process-queue-missing-parens into main

Fixes #142 - process_queue silently skips all queue items because
issue_ref and message Python extraction commands were missing a closing
parenthesis. The error was silently swallowed by 2>/dev/null causing
both variables to be empty, so every queue item was skipped.

+# 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

+### 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)

+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
