# NaviDocs Launch Checklist System

**IF.TTT Citation:** `if://doc/navidocs/launch-checklist-system/v1.0`
**Created:** 2025-11-13
**Purpose:** Bulletproof launch verification system for zero-failure demos

---

## Overview

This system provides **four automated scripts** that ensure NaviDocs always launches correctly and catches issues before they cause demo failures. Based on comprehensive analysis of Agent reports 1-5, these scripts address all known failure modes.

### Scripts

1. **`pre-launch-checklist.sh`** - Run BEFORE starting services
2. **`verify-running.sh`** - Run AFTER starting services
3. **`debug-logs.sh`** - Aggregate all logs for rapid debugging
4. **`version-check.sh`** - Verify exact running version

---

## Quick Start

```bash
# 1. Pre-flight check (MUST RUN FIRST)
./pre-launch-checklist.sh

# 2. Start services (only if pre-check passes)
./start-all.sh

# 3. Verify everything is working (within 30 seconds)
./verify-running.sh

# 4. If issues detected, debug
./debug-logs.sh
```

---

## Script 1: Pre-Launch Checklist (`pre-launch-checklist.sh`)

### Purpose
Verify system state BEFORE starting services to catch issues early.

### What It Checks

**IF.TTT Citations:**
- `if://agent/1/findings/backend-health` - Backend API health
- `if://agent/2/findings/port-fallback` - Vite port fallback behavior
- `if://agent/3/findings/database-size` - Database integrity
- `if://agent/5/findings/meilisearch-index-missing` - Search index status

#### 1. Git Repository State
- Current commit hash and branch
- Uncommitted changes detection
- Recent commits (helps identify version)

#### 2. Port Availability
- **Port 8001** - Backend API (will be killed if occupied)
- **Port 8080** - Frontend Vite primary (will be killed if occupied)
- **Port 8081** - Frontend Vite fallback (warning only)
- **Port 7700** - Meilisearch (can be running)
- **Port 6379** - Redis (can be running)

**Critical Finding (Agent 2):** Vite automatically falls back to 8081 if 8080 is occupied. The script detects this and warns accordingly.

#### 3. Node.js Version
- **Required:** `v20.19.5`
- **Acceptable:** Any v20.x (warns on minor version mismatch)
- **Fails:** Any other major version

#### 4. Database Integrity
- File exists at `/home/setup/navidocs/server/db/navidocs.db`
- Readable and not locked
- Document count verification
- **IF.TTT:** `if://agent/3/findings/documents-count/[N]`

#### 5. Redis Connectivity
- Redis server responding to `PING`
- **Critical for:** Job queue (OCR processing)

#### 6. Meilisearch Status
- Docker container running
- HTTP health endpoint responding
- **Critical Check:** `navidocs-pages` index exists
  - **Agent 5 Finding:** Index missing causes OCR to fail silently
  - **IF.TTT:** `if://agent/5/findings/meilisearch-index-missing`

#### 7. Dependencies Installed
- Server `node_modules` exists (package count)
- Client `node_modules` exists (package count)

#### 8. Zombie Process Detection
- Existing backend processes (will be killed)
- Existing frontend processes (will be killed)
- Existing OCR worker processes (will be killed)

#### 9. Log Files Accessible
- `/tmp` directory writable
- Previous log files detected (size and age)

#### 10. Environment Configuration
- `.env` file exists (optional)
- **Agent 1 Warning:** `SETTINGS_ENCRYPTION_KEY` not set
  - **Impact:** Settings won't persist across restarts
  - **Fix:** Generate with `node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"`
  - **IF.TTT:** `if://agent/1/findings/settings-encryption-key`

#### 11. Docker Status
- Docker daemon running
- Meilisearch container status (running/stopped/missing)

#### 12. Uploads Directory
- Directory exists at `/home/setup/navidocs/uploads`
- Writable by current user
- **IF.TTT:** `if://agent/5/findings/uploads-directory`

### Exit Codes
- **0** - All checks passed (safe to launch)
- **0** - Warnings only (safe to launch with degraded features)
- **1** - Critical failures (DO NOT LAUNCH)

### Example Output
```

## Common Failure Modes & Recovery

Based on Agent reports 1-5, here are the most common issues and how the scripts detect/fix them:

### 1. Meilisearch Index Missing
**Agent 5 Finding:** `if://agent/5/findings/meilisearch-index-missing`

**Symptom:** OCR completes but search doesn't work
**Detected by:** `pre-launch-checklist.sh` (warns), `verify-running.sh` (checks index stats)
**Fix:**
```bash
curl -X POST http://localhost:7700/indexes \
  -H 'Authorization: Bearer 5T66jrwQ8F8cOk4dUlFY0Vp59fMnCsIfi4O6JZl9wzU=' \
  -d '{"uid":"navidocs-pages"}'
```

### 2. Port 8080 Occupied (Vite Fallback)
**Agent 2 Finding:** `if://agent/2/findings/port-fallback`

**Symptom:** Frontend runs on port 8081 instead of 8080
**Detected by:** `pre-launch-checklist.sh` (warns about both 8080 and 8081)
**Fix:** Kill process on port 8080 before running `start-all.sh`

### 3. Settings Encryption Key Missing
**Agent 1 Finding:** `if://agent/1/findings/settings-encryption-key`

**Symptom:** Settings don't persist across restarts
**Detected by:** `pre-launch-checklist.sh` (warns)
**Fix:**
```bash
# Generate key
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

# Add to server/.env
echo "SETTINGS_ENCRYPTION_KEY=<generated-key>" >> server/.env
```

### 4. Zombie Backend Processes
**Symptom:** Backend fails to start (port already in use)
**Detected by:** `pre-launch-checklist.sh` (warns, shows PIDs)
**Fix:** `start-all.sh` kills existing processes automatically

### 5. Database Locked
**Symptom:** API returns 500 errors on database queries
**Detected by:** `pre-launch-checklist.sh` (tries test query), `verify-running.sh` (database access check)
**Fix:** Stop all services, ensure no SQLite processes, restart

### 6. OCR Worker Not Processing
**Symptom:** Documents stuck in "processing" status
**Detected by:** `verify-running.sh` (checks worker process + E2E test), `debug-logs.sh` (OCR queue stats)
**Fix:** Check OCR worker logs, ensure Redis queue accessible

### 7. Frontend Returns 404
**Symptom:** Blank page or "Cannot GET /"
**Detected by:** `verify-running.sh` (checks for Vue app div in HTML)
**Fix:** Check frontend logs for Vite compilation errors

## Integration with Existing Scripts

### Before Demo Workflow
```bash
# 1. Stop any running services
./stop-all.sh

# 2. Pre-flight check
./pre-launch-checklist.sh
# Exit code 0 = safe to launch
# Exit code 1 = fix failures first

# 3. Start services
./start-all.sh

# 4. Verify everything works
./verify-running.sh
# Exit code 0 = demo ready
# Exit code 1 = check debug logs

# 5. Optional: Check logs if issues
./debug-logs.sh
```

### Version Documentation Workflow
```bash
# Before demo, document exact version
./version-check.sh > /tmp/navidocs-version-$(date +%Y%m%d).txt

# Save fingerprint for reproducibility
grep "Version Fingerprint" /tmp/navidocs-version-*.txt
```

---

## Troubleshooting

### Script Won't Run
```bash
# Make executable
chmod +x pre-launch-checklist.sh verify-running.sh debug-logs.sh version-check.sh

# Check for DOS line endings (if copied from Windows)
dos2unix *.sh
```

### False Positives
Some warnings are expected in development:
- `SETTINGS_ENCRYPTION_KEY not set` - Non-critical for local dev
- `Port 8081 occupied` - Informational (Vite will use 8082)
- `Uncommitted changes detected` - Normal during development

### Script Hangs
If a script appears to hang:
- **Check:** Network timeouts (Meilisearch, Redis)
- **Fix:** Increase timeout in script (default: 3-5s)
- **Kill:** `Ctrl+C` (scripts use `set -e`, safe to interrupt)

---

## Maintenance

### When to Update Scripts

1. **New service added** - Add to pre-launch and verify-running checks
2. **Port changes** - Update port numbers in all scripts
3. **New critical dependency** - Add to pre-launch dependencies check
4. **New failure mode discovered** - Add detection logic and IF.TTT citation

### Testing Scripts

After modifications, test with:
```bash
# Test pre-launch with services stopped
./stop-all.sh
./pre-launch-checklist.sh
# Should show warnings for stopped services

# Test verify-running with services running
./start-all.sh
./verify-running.sh
# Should pass all checks

# Test debug-logs
./debug-logs.sh 50  # Show last 50 lines
```

---

## Performance

### Script Execution Times
- `pre-launch-checklist.sh`: 5-10 seconds (comprehensive)
- `verify-running.sh`: 20-30 seconds (includes E2E test)
- `debug-logs.sh`: 2-5 seconds (depends on log size)
- `version-check.sh`: 3-5 seconds

### Optimization Tips
- Run `pre-launch-checklist.sh` only once before startup
- Run `verify-running.sh` after startup and before demos
- Use `debug-logs.sh 100` (default) for quick checks, `500+` for deep debugging
