+# PicPeak POSTs event/photo lifecycle notifications to URLs you configure

+# per-webhook secret in the X-PicPeak-Signature header.
+#
+# WEBHOOK_ALLOW_PRIVATE_URLS (default: false)

+# WEBHOOK_DELIVERY_INTERVAL_MS (default: 5000)
+#   How often the worker polls webhook_deliveries for pending rows.
+# WEBHOOK_DELIVERY_INTERVAL_MS=5000
+#
+# WEBHOOK_DELIVERY_CONCURRENCY (default: 5)
+#   Maximum in-flight deliveries per worker tick. One slow consumer can
+#   monopolize all 5 slots — bump this if your receivers are slow OR ship
+#   a separate webhook-only deployment.
+# WEBHOOK_DELIVERY_CONCURRENCY=5
+#
+# WEBHOOK_HTTP_TIMEOUT_MS (default: 10000)
+#   Per-request timeout. Beyond this, the delivery is recorded as a
+#   network error and retried.
+# WEBHOOK_HTTP_TIMEOUT_MS=10000
+#
+# WEBHOOK_MAX_ATTEMPTS (default: 5)
+#   Total attempts before a delivery is marked failed. Backoff between
+#   attempts is exponential: 1m, 5m, 30m, 2h, 12h.

+# Verifies that `migrate:safe` can recover a DB that's been seeded only
+# by `initializeDatabase()` — the recovery scenario where the migrations
+# tracking table is empty but the schema already has the modern bootstrap.
+#
+# This is NOT how production reaches its state on normal installs or
+# upgrades. The scenario only fires when:
+#   - A backup was restored that captured tables but not the migrations
+#     table (manifest divergence),
+#   - Someone manually invoked initializeDatabase() outside the migration
+#     runner (recovery / debugging),
+#   - The DB was moved between systems and the migrations table was not
+#     copied along.
+#
+# When `detectExistingSchema()` sees the modern-bootstrap fingerprint
+# (photo_categories + cms_pages tables) but an empty migrations table,
+# it treats it as an "existing deployment" — which runs the legacy
+# chain first. Legacy/008 renames email_templates.subject → subject_en,
+# but core/029 (which runs later in this chain) inserts email templates
+# referencing the pre-rename column name. The chain dies with a
+# "column subject does not exist" error.
+#
+# Fix (in the same PR as this workflow): when the modern-bootstrap
+# fingerprint is detected, mark all legacy migrations as applied so the
+# chain matches what a fresh install runs — only core/*, in order.

+# What's New highlights — GitHub Models release step (reusable)
+#
+# Called by the release-please workflows AFTER a release is created
+# (release-please.yml for `stable`, release-please-beta.yml for `main`). It runs
+# as a job in the SAME workflow run rather than on its own `release: published`
+# trigger, because release-please creates the release with the default
+# GITHUB_TOKEN and GitHub does not start new workflow runs from token-generated
+# events — a standalone `release:` workflow would simply never fire.
+#
+# What it does: condenses the new release's "### Features" into <=8 short
+# bullets via GitHub Models (free tier, `models: read`) and injects a
+# `<!-- whatsnew -->` block at the top of the release notes. The app reads that
+# block (backend utils/whatsNew.parseWhatsNew) and falls back to the raw
+# Features list for releases without it — so this is purely a quality upgrade,
+# never a hard dependency. Failure is isolated by `continue-on-error` + the
+# deterministic fallback below, so it can never break a release.
+#
+# GitHub Models is OPTIONAL. If it is disabled/unavailable for the org the AI
+# step fails soft (continue-on-error) and the deterministic fallback produces
+# the bullets instead — the feature works either way, Models just polishes them.
+#
+# Validated end-to-end on a fork (extract -> openai/gpt-4o-mini -> inject into

-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Product Overview
-
-A secure photo sharing platform designed for weddings and events, enabling photographers to share time-limited, password-protected galleries. The platform features automatic expiration, archiving, and a scrappbook.de-inspired modern, minimalist UI.
-
-## Architecture Overview
-
-- **Backend**: Node.js/Express API with SQLite/PostgreSQL, file-based photo storage
-- **Frontend**: React SPA with scrappbook.de-style design (requires implementation)
-- **Storage**: File-based with active/archived separation
-- **Services**: Background workers for email, archiving, file watching, and expiration monitoring
-- **Analytics**: Umami integration for engagement tracking
-
-## Essential Commands
-
-### Backend Development
-```bash
-cd backend
-npm install               # Install dependencies
-npm run migrate          # Initialize database schema
-npm run dev              # Start with hot-reload (port 3001)
-npm test                 # Run Jest tests
-npm run lint             # ESLint checks
-```
-
-### Running a Single Test
-```bash
-cd backend
-npm test -- path/to/test.test.js
-npm test -- --testNamePattern="test name"
-```
-
-### Production Deployment
-See [DEPLOYMENT_GUIDE.md](./DEPLOYMENT_GUIDE.md) for comprehensive deployment instructions including:
-- Docker Compose deployment
-- PM2 deployment
-- Manual installation
-- Non-nginx deployment options
-- SSL/HTTPS setup
-- Troubleshooting guide
-
-**⚠️ CRITICAL PRODUCTION NOTICE:**
-- Production runs on a SEPARATE SERVER - never assume local changes affect production
-- ALWAYS request production server details before any troubleshooting
-- NO trial-and-error approaches in production - data loss is unacceptable
-- Every change must be thoroughly analyzed and tested locally first
-
-## Key Product Requirements (from PRD)
-
-### Core Features
-1. **File-Based System**: Drop photos in folders → automatic gallery creation
-2. **Automatic Expiration**: Default 30 days, with 7-day warning emails
-3. **Password Protection**: Secure access with customizable passwords
-4. **Automatic Archiving**: ZIP compression and storage after expiration
-5. **Email Notifications**: Creation, warning, and expiration notifications
-6. **Analytics**: Umami tracking for views, downloads, and engagement

-
-## Frontend Implementation Requirements
-
-### Design Style (scrappbook.de-inspired)
-- **Color Palette**: Primary green (#5C8762), neutral backgrounds
-- **Typography**: Clean, modern sans-serif (Noto Sans or similar)
-- **Layout**: Minimalist, modular sections with grid-based photo displays
-- **Aesthetic**: Professional yet approachable, photographer-focused
-
-### Key Frontend Components to Build
-1. **Landing Page**: Password entry with event preview
-2. **Gallery View**: 
-   - Responsive photo grid with lazy loading
-   - Toggle between collages/individual photos
-   - Prominent expiration banner
-   - Download urgency indicators
-3. **Photo Lightbox**: Full-screen viewing with zoom
-4. **Mobile-First**: Responsive design with touch gestures
-5. **Personalization**: Dynamic theming per event type
-
-### User Experience Priorities
-- Clear expiration warnings (sticky banner)
-- One-click "Download All" for urgent galleries
-- Smooth image loading with skeleton screens
-- Intuitive navigation between photo categories
-- Professional presentation matching photographer branding
-
-## Key Architecture Patterns
-
-### Authentication Flow
-- JWT-based with separate tokens for admin and gallery access
-- Gallery tokens include event-specific claims
-- Auth middleware: `backend/src/middleware/auth.js`
-  - `adminAuth` - Admin panel protection
-  - `photoAuth` - Protected photo access  
-  - `verifyGalleryAccess` - Gallery-specific validation
-
-### Database Schema (Knex/SQLite)
-Main tables:
-- `events` - Gallery metadata with expiration, custom messages, themes
-- `photos` - Photo records linked to events
-- `access_logs` - IP-based usage tracking
-- `email_queue` - Async email processing
-- `admin_users` - Admin authentication
-
-### Service Architecture
-Background services run as separate processes:
-- **emailService**: Processes email queue with retry logic
-- **archiveService**: Creates ZIP archives of expired events
-- **expirationChecker**: Cron job for expiration warnings
-- **fileWatcher**: Monitors for new photo uploads
-- **backupService**: Scheduled backups with checksum-based change detection
-
-### API Structure
-- `/api/admin/*` - Admin panel endpoints (requires adminAuth)
-- `/api/gallery/*` - Public gallery endpoints  
-- `/api/auth/*` - Authentication endpoints
-- Rate limiting: 100 req/15min (general), 5 req/15min (auth)
-
-## Critical Implementation Notes
-
-1. **Security**: All gallery access requires valid JWT with event-specific claims
-2. **Expiration**: Events auto-expire based on `expires_at`, with 7-day email warnings
-3. **Email Queue**: Async processing with retry logic, check `email_queue` table
-4. **File Processing**: Sharp library for thumbnail generation (300x300)
-5. **Frontend Status**: Only skeleton exists - requires full implementation based on PRD
-6. **Umami Analytics**: Track password entries, downloads, views, expiration warnings
-
-## Troubleshooting Guidelines
-
-### Before ANY Production Troubleshooting:
-1. **ALWAYS request specific details**:
-   - Production server URL/IP
-   - Current error messages/logs
-   - Recent changes or deployments
-   - Affected users/galleries
-   - Time of issue occurrence
-
-2. **Thorough Analysis Required**:
-   - Use detailed thinking/analysis for EVERY troubleshooting task
-   - Review all related code before suggesting changes
-   - Consider all potential side effects
-   - Never make assumptions about production environment
-
-3. **Safe Troubleshooting Steps**:
-   - First, reproduce issue in local/dev environment
-   - Analyze logs without modifying production
-   - Create detailed action plan before any changes
-   - Always have rollback strategy ready
-   - Document every step taken
-
-### Common Issues & Safe Approaches:
-- **Email not sending**: Check email_queue table, SMTP settings, service status
-- **Photos not loading**: Verify file permissions, storage paths, nginx config
-- **Gallery access issues**: Check JWT tokens, expiration dates, access_logs
-- **Performance problems**: Analyze with monitoring tools first, never experiment
-
-### Data Safety Rules:
-- NEVER delete or modify production data without explicit backup confirmation
-- ALWAYS verify backups exist before any data operations
-- NO direct database modifications without transaction safety
-- Log all actions for audit trail
-
-## Environment Variables
-
-### Backend (.env)
-- `JWT_SECRET` - Token signing
-- `ADMIN_URL`, `FRONTEND_URL` - CORS origins
-- `SMTP_*` - Email configuration
-- `DB_*` - PostgreSQL credentials (production)
-- `UMAMI_URL` - Umami instance URL (for server-side tracking)
-- `UMAMI_WEBSITE_ID` - Website ID from Umami
-
-### Frontend (.env)

-
-## Testing Approach
-- Jest with Supertest for API testing
-- Test files in `__tests__` directories
-- Database migrations run before tests
-- Mock email sending in tests
-
-## Umami Analytics Integration
-
-The frontend includes comprehensive Umami analytics integration for tracking user behavior and gallery performance.
-
-### Tracked Events:

-
-## Backup Service
-
-### Overview
-The backup service provides automated, scheduled backups of all photo data with checksum-based change detection to minimize transfer overhead.
-
-### Features
-- **Multiple Destinations**: Local directory, remote server (rsync), S3-compatible storage
-- **Change Detection**: SHA256 checksums track file changes, only modified files are backed up
-- **Scheduled Execution**: Configurable cron-based scheduling (default: 2 AM daily)
-- **Email Notifications**: Alerts on backup failure, optional success notifications
-- **Retention Management**: Automatic cleanup of old backup runs based on retention policy
-- **Progress Tracking**: Database storage of backup history, file states, and statistics
-
-### Configuration
-Backup settings are stored in `app_settings` table with `backup_` prefix:
-- `backup_enabled`: Enable/disable the service
-- `backup_schedule`: Cron expression (e.g., '0 2 * * *')
-- `backup_destination_type`: 'local', 'rsync', or 's3'
-- `backup_retention_days`: How long to keep backup history
-- `backup_include_archived`: Whether to backup archived events
-- `backup_exclude_patterns`: File patterns to exclude
-
-### API Endpoints
-- `GET /api/admin/backup/config` - Get current configuration
-- `PUT /api/admin/backup/config` - Update configuration
-- `GET /api/admin/backup/status` - Get backup status and history
-- `POST /api/admin/backup/run` - Trigger manual backup
-- `POST /api/admin/backup/test-connection` - Test destination connectivity
-
-### Testing
-Run backup service test: `npm run test-backup`
-
-### Database Tables
-- `backup_runs`: Tracks each backup execution with statistics
-- `backup_file_states`: Stores file checksums for change detection
-
-## Thumbnail Generation
-
-### Square Thumbnail Implementation (Issue #12 Fix)
-The system now generates **square 300x300px thumbnails** to prevent blurry/stretched images in the gallery grid:
-
-- **Problem**: Previously generated 300px width with proportional height (e.g., 300x200 for 3:2 photos), but CSS forced square display causing distortion
-- **Solution**: Thumbnails now use `cover` fit mode to crop to exact 300x300px dimensions with center positioning
-- **Configuration**: Settings stored in `app_settings` table with keys: `thumbnail_width`, `thumbnail_height`, `thumbnail_fit`, `thumbnail_quality`, `thumbnail_format`
-- **Migration**: Run `040_add_thumbnail_settings.js` to add default square thumbnail settings
-- **Regeneration Script**: Use `scripts/regenerate-square-thumbnails.js` to update existing thumbnails
-
-### Thumbnail Settings API
-- `GET /api/admin/thumbnails/settings` - Get current thumbnail configuration
-- `PUT /api/admin/thumbnails/settings` - Update thumbnail settings (requires regeneration)
-- `POST /api/admin/thumbnails/regenerate` - Regenerate all thumbnails with new settings
-- `GET /api/admin/thumbnails/regenerate/status` - Check regeneration progress
-
-## Success Metrics (from PRD)
-- Time to generate gallery: <2 minutes
-- Guest satisfaction: >90%
-- System uptime: 99.9%
-- Email delivery rate: >98%
-- Successful archiving: 100%
-
-## Documentation & Development Practices
-
-### Documentation Guidelines:
-- **NEVER create new documentation files for simple tasks**
-- **ALWAYS update existing documentation (like this CLAUDE.md)**
-- Only create new .md files when explicitly requested
-- Avoid creating temporary scripts for one-off tasks
-
-### Development Best Practices:
-- Test all changes thoroughly in local environment first
-- Use version control for all changes
-- Keep commits atomic and well-described
-- Review impact on all integrated services
-- Consider backward compatibility
-- Update tests when changing functionality
-
-### Production Deployment Checklist:
-- [ ] All tests passing locally
-- [ ] Linting and type checks pass
-- [ ] Database migrations tested with rollback plan
-- [ ] Environment variables documented
-- [ ] Backup strategy confirmed
-- [ ] Monitoring alerts configured
-- [ ] Rollback procedure documented
-- [ ] Stakeholders notified of maintenance window
-- always use docker deployment for testing

+## 🌿 Branch model
+
+PicPeak runs on two long-lived branches:
+
+| Branch | Role | What targets it |
+|---|---|---|
+| **`main`** | Active development. The next release is being assembled here. | Feature PRs. Most bugfix PRs. |
+| **`stable`** | Curated release channel. Production-recommended. | Urgent bugfix backports only — small, surgical PRs that land cleanly without dragging in unrelated changes. |
+
+### Which branch should my PR target?
+
+- **New feature** → target `main`.
+- **Bugfix that ONLY affects active dev** → target `main`.
+- **Bugfix that current stable users need** → open a small PR against `main`, AND a separate small PR against `stable` with the same change. Keep both surgical so each lands cleanly.
+
+**Hard rule on PR scope**: bugfix PRs against `stable` must be small enough to backport without conflict. Omnibus PRs (e.g. five unrelated sub-features) are fine for `main`, but never for `stable` — they make the next `main → stable` merge painful and break the "stable is always shippable" invariant.
+
+If you're not sure which branch to target, default to `main` and a maintainer will retarget during review.
+
 ## 🔄 Release Process
 
-1. Update version numbers in package.json files
-2. Update CHANGELOG.md
-3. Create a new release on GitHub
-4. Docker images are automatically built and published
+Releases are cut independently from `main` (pre-release versions for the active channel) and `stable` (semver releases for the curated channel). `release-please` handles version bumps, changelog generation, and Docker image publication automatically — contributors don't update `package.json` or `CHANGELOG.md` by hand.
+
+Periodic `main → stable` merges promote a batch of `main` work to the stable channel. The maintainer chooses when (typically every ~4 weeks, sooner if a hot bug demands it).
+
+See [RELEASING.md](RELEASING.md) for the full operational doc (promotion criteria, conflict-resolution checklist for the `main → stable` merge, hotfix backport path, versioning rules).

-## 🐳 Docker Compose Deployment
-
-### Option 1: Using Pre-built Images (Recommended)
-
-PicPeak provides official Docker images via GitHub Container Registry for quick deployment without building:
-
-```bash
-# Clone repository for configuration files
-git clone https://github.com/the-luap/picpeak.git
-cd picpeak
-
-# Copy and configure environment
-cp .env.example .env
-nano .env  # Edit with your values
-
-# Use pre-built images deployment
-docker compose -f docker-compose.production.yml up -d
-```
-
-The production compose file uses:
-- **Backend**: `ghcr.io/the-luap/picpeak/backend:latest`
-- **Frontend**: `ghcr.io/the-luap/picpeak/frontend:latest`
-
-Available tags:
-- `latest` - Latest stable release
-- `main` - Latest main branch build
-- `develop` - Development branch (may be unstable)
-- `v1.0.0` - Specific version tags
-
-### Option 2: Building from Source
-
-If you need to customize the application or the pre-built images aren't available, you can build locally:

-   ```
-
-## External Media Library
-
-PicPeak can reference an existing, read‑only media library mounted into the backend container. This avoids copying originals into PicPeak storage.
-
-- Map your host library path to the container as read‑only in `docker-compose.production.yml`:
-  - Add volume under `backend`: `- ${EXTERNAL_MEDIA}:/external-media:ro`
-  - Add backend env: `EXTERNAL_MEDIA_ROOT=/external-media`
-- In `.env`, set:
-  - `EXTERNAL_MEDIA=/mnt/photos` (example host path)
-  - `EXTERNAL_MEDIA_ROOT=/external-media`
-
-Usage:
-- In Admin → Events, set “Source Mode” to “Reference (external folder)”, select a folder under `/external-media`, then import to index and generate thumbnails. Originals stay in your library.
-
-Backups and Archives:
-- Backups only include data under `STORAGE_PATH` and exclude external originals. The backup manifest includes `metadata.external_references = { excluded: true, events: N, photos: M }` and the Admin UI surfaces a warning.
-- Archiving reference events creates a manifest‑only ZIP and deletes thumbnails for that event. External originals are never moved or deleted.
-
-Local (npm) setup (no Docker):
-
-1. Create or choose a folder that contains your external originals, e.g. `/Users/you/Pictures/picpeak-external` (macOS/Linux) or `C:\\Pictures\\picpeak-external` (Windows).
-2. In `backend/.env` (or your shell), set:
-   - `EXTERNAL_MEDIA_ROOT=/absolute/path/to/picpeak-external`
-   - Ensure `STORAGE_PATH` points to your PicPeak storage (defaults to `./storage`).
-3. Start services from source:
-   - Backend: `cd backend && npm install && npm run migrate && JWT_SECRET=... npm start`
-   - Frontend: `cd frontend && npm install && npm run dev` (or build + serve)
-4. In Admin → Events:
-   - Create an event, set “Source Mode” to “Reference (external folder)”.
-   - Use the folder picker to browse under your `EXTERNAL_MEDIA_ROOT` and select the subfolder to reference.
-   - Click “Import from selected folder” to index files and generate thumbnails on demand.
-
-Notes:
-- PicPeak only reads from `EXTERNAL_MEDIA_ROOT`; it never modifies or deletes your originals there.
-- Thumbnails are generated under `STORAGE_PATH/thumbnails` and are included in backups; originals in `EXTERNAL_MEDIA_ROOT` are excluded.
-- On Windows, use absolute paths (e.g., `C:\\Photos\\Library`) for `EXTERNAL_MEDIA_ROOT`.
-
-### Method 2: Building from Source
-
-1. **Clone the repository**
-   ```bash
-   git clone https://github.com/the-luap/picpeak.git
-   cd picpeak
-   ```
-
-2. **Set up environment**
-   ```bash
-   cp .env.example .env
-   nano .env  # Edit with your values
-   ```
-
-3. **Create required directories**
-   ```bash
-   mkdir -p events/active events/archived data logs backup storage
-   chmod -R 755 events data logs backup storage
-   ```
-
-4. **Build and deploy**
-   ```bash
-   docker compose build
-   docker compose up -d
-   ```
-
-5. **Check logs**
-   ```bash
-   docker compose logs -f
-   ```
-
-## 🔧 Configuration
-
-### Essential Environment Variables
-
-Generate secure values:
-```bash
-# JWT Secret
-openssl rand -base64 64
-
-# Database Password (avoid $ character - see warning below)
-openssl rand -base64 32 | tr -d '$'
-
-# Redis Password (avoid $ character - see warning below)
-openssl rand -base64 32 | tr -d '$'
-```
-
-⚠️ **PASSWORD WARNING**: Docker Compose interprets `$` as variable substitution. Either:
-- Avoid `$` in passwords (recommended - use the commands above)
-- Escape `$` as `$$` (e.g., `Pass$$word` instead of `Pass$word`)
-- Quote the entire value: `DB_PASSWORD='Pass$word'` (less reliable)
-
-### Public Landing Page
-
-- `npm run migrate` now seeds three general settings: `general_public_site_enabled`, `general_public_site_html`, and `general_public_site_custom_css` so existing installs stay disabled by default.
-- Configure the feature from **Admin → CMS Pages**. The landing page panel exposes the toggle, HTML editor, optional CSS overrides, preview, and a reset-to-default action.
-- All HTML and CSS submitted through the UI is sanitized server-side. Scripts, inline event handlers, disallowed attributes, `@import` rules, and `javascript:` URLs are stripped before content is cached or rendered.
-- Resetting via the UI (or calling `POST /api/admin/settings/public-site/reset`) restores the bundled template and clears custom CSS.
-- The landing page response is cached in-memory. Override the default 60s cache window by setting `PUBLIC_SITE_CACHE_TTL_MS` (milliseconds) in your environment if you need faster cache busting.
-- When the toggle is off PicPeak continues to serve the SPA/login redirect at `/`, preserving legacy behaviour until you explicitly enable the feature.
-
-### Backend Configuration (.env)
-Update `.env` with:
-- `JWT_SECRET` - Authentication secret (REQUIRED - generate a secure random value)
-- `DB_PASSWORD` - PostgreSQL password
-- `REDIS_PASSWORD` - Redis password
-- `SMTP_*` - Email configuration
-- **URL Configuration** (for backend CORS):
-  - `FRONTEND_URL` - Frontend origin (use full URL with scheme, no trailing slash)
-    - Example (Docker): `http://localhost:3000`
-  - `ADMIN_URL` - Admin origin (same as `FRONTEND_URL` for Docker; full URL, no trailing slash)
-    - Example (Docker): `http://localhost:3000`
-  
-  Notes:
-  - Do not include trailing `/` (e.g., use `http://host:3000`, not `http://host:3000/`).
-  - Always include the scheme (`http://` or `https://`).
-  - The backend compares origins strictly for CORS; malformed values will cause login requests to fail with 500.
-
-#### External Database Example
-To use an external PostgreSQL instead of the bundled container, set the following in `.env` and ensure the `postgres` service is disabled or removed:
-
-```env
-DB_HOST=db.example.com
-DB_PORT=5432
-DB_USER=picpeak
-DB_PASSWORD=change_me
-DB_NAME=picpeak_prod
-```
-
-Compose uses these values via `env_file: .env`. The backend service also defaults `DB_HOST=${DB_HOST:-postgres}` so if you don’t set `DB_HOST` it will use the bundled `postgres` container.
-
-### Frontend Configuration (frontend/.env)
-Create `frontend/.env` from `frontend/.env.example`:
-```bash
-cp frontend/.env.example frontend/.env
-```
-
-Update `frontend/.env` with:
-- `VITE_API_URL` - Backend API URL
-  - Docker (pre-built images) and production behind reverse proxy: `/api` (recommended; avoids CORS and matches the frontend Nginx proxy in the image)
-  - Local dev (Vite): `http://localhost:3001` or `/api` if proxying through a dev proxy
-
-Note: When using pre-built frontend images, runtime container env does not change the already-built JS. Prefer the default `/api` and let the frontend Nginx proxy forward to the backend.
-
-⚠️ **IMPORTANT PORT CONFIGURATION**: 
-- The frontend runs on port **3000** in Docker (exposed via nginx)
-- The backend API runs on port **3001**
-- The frontend `.env` file MUST point to the correct backend port (3001)
-- Default `.env.example` is configured for Docker deployment
-
-### Email Configuration Examples
-
-#### Gmail
-```env
-SMTP_HOST=smtp.gmail.com
-SMTP_PORT=587
-SMTP_SECURE=false
-SMTP_USER=your-email@gmail.com
-SMTP_PASS=your-app-specific-password
-```
-
-#### SendGrid
-```env
-SMTP_HOST=smtp.sendgrid.net
-SMTP_PORT=587
-SMTP_SECURE=false
-SMTP_USER=apikey
-SMTP_PASS=your-sendgrid-api-key
-```
-
-## 📦 Deployment
-
-### Using Pre-built Images (Fastest)
-
-```bash
-# Pull latest images from GitHub Container Registry
-docker pull ghcr.io/the-luap/picpeak/backend:latest
-docker pull ghcr.io/the-luap/picpeak/frontend:latest
-
-# Start services using production compose file
-docker compose -f docker-compose.production.yml up -d
-
-# View running containers
-docker compose ps
-```
-
-### Building from Source (For Customization)
-
-```bash
-# Build images locally
-docker compose build
-
-# Or build with no cache for clean build
-docker compose build --no-cache
-
-# Start all services
-docker compose up -d
-
-# View running containers
-docker compose ps
-```
-
-### Access Points
-
-By default, services are exposed on:
-- Frontend (UI + Admin): http://localhost:3000 (admin at `/admin`)
-- Backend/API: http://localhost:3001 (API only; no UI routes)
-- PostgreSQL: localhost:5432 (if needed)
-- Redis: localhost:6379 (if needed)
-
-### Initial Admin Setup
-
-When deploying for the first time, an admin account is automatically created with a secure, randomly generated password. This password is displayed in the Docker logs during initialization and **must be changed** on first login.
-
-#### Finding the Auto-Generated Admin Password
-
-The admin password is automatically generated during the first startup and displayed in the backend container logs. Here's how to find it:
-
-**Option 1: Search Docker logs for admin password** (recommended)
-```bash
-# Find the auto-generated admin password in logs
-docker compose logs backend | grep "Admin password"
-```
-
-You should see output like:
-```
-✅ Admin password generated: BraveTiger6231!
-```
-
-**Option 2: View the complete initialization logs**
-```bash
-# View the complete admin setup logs
-docker compose logs backend | grep -A 10 "Admin user created"
-```
-
-**Option 3: Check the saved credentials file**
-```bash
-# The password is also saved in the backend container
-docker exec picpeak-backend cat data/ADMIN_CREDENTIALS.txt
-```
-
-**Option 4: Use the helper script**
-```bash
-# Show current admin username and email (password is hidden)
-docker exec picpeak-backend node scripts/show-admin-credentials.js
-
-# Reset the admin password to a new random password
-docker exec picpeak-backend node scripts/show-admin-credentials.js --reset
-```
-
-#### Important Security Notes
-
-- **Login requires the email address**, not username
-- The admin password is only displayed once during initial setup
-- **Password change is MANDATORY** on first login - the system will force you to change it
-- If you lose the password before first login, use the `--reset` option to generate a new one
-- New password requirements: minimum 12 characters, mixed case, numbers, and special characters
-
-## 🔐 First Login
-
-After deployment, you must complete the first login process which includes mandatory password change for security.
-
-### Step 1: Locate Your Admin Password
-
-1. **Find the auto-generated password** from the credentials file:
-   ```bash
-   # Docker deployment
-   docker compose exec backend cat /app/data/ADMIN_CREDENTIALS.txt
-   
-   # Or directly from the host (if you have access)
-   cat data/ADMIN_CREDENTIALS.txt
-   ```
-
-2. **Note the admin email** (default: `admin@example.com` unless customized)
-
-### Step 2: Access Admin Panel
-
-1. Navigate to your frontend domain and open the admin section:
-   - `http://your-domain.com/admin` (behind reverse proxy)
-   - `http://localhost:3000/admin` (Docker local)
-   
-   The backend at `:3001` serves API only and does not serve the admin UI.
-2. Login using:
-   - **Email**: `admin@example.com` (or your custom admin email)
-   - **Password**: The auto-generated password from the logs
-
-### Step 3: Mandatory Password Change
-
-Upon first login, the system will **automatically redirect** you to change your password:
-
-1. **You cannot skip this step** - it's enforced for security
-2. Enter the current auto-generated password
-3. Create a new secure password meeting these requirements:
-   - Minimum 12 characters
-   - At least one uppercase letter
-   - At least one lowercase letter
-   - At least one number
-   - At least one special character (!@#$%^&*)
-
-### Security Best Practices for New Password
-
-- **Use a unique password** not used elsewhere
-- **Consider a password manager** for generation and storage
-- **Include mixed characters**: `MySecureP@ssw0rd2024!`
-- **Avoid personal information** (names, dates, etc.)
-- **Save securely** - you cannot recover this password easily
-
-### If You Lose Access
-
-If you lose your admin credentials after the first login, you'll need to manually reset the password in the database or create a new admin user through the database.
-
-**Note**: The credentials file (`ADMIN_CREDENTIALS.txt`) is only created during initial deployment and contains the first admin password. After changing the password, this file becomes outdated but is kept for reference.
-
-#### Configuring Admin Email
-
-By default, the admin email is `admin@example.com`. To use a different email address, set it in your `.env` file before first deployment:
-
-```env
-# .env
-ADMIN_EMAIL=your-email@yourdomain.com
-```
-
-**Note**: This only works on first deployment. To change the admin email after deployment, you'll need to update it in the database or create a new admin user through the admin panel.
-
-## 🔒 Reverse Proxy Setup
-
-For production deployments, you should use a reverse proxy for SSL/HTTPS. The application exposes ports directly, allowing you to use any reverse proxy solution.
-
-### Option 1: Nginx
-
-Install nginx and create `/etc/nginx/sites-available/picpeak`:
-
-```nginx
-server {
-    listen 80;
-    server_name your-domain.com;
-    return 301 https://$server_name$request_uri;
-}
-
-server {
-    listen 443 ssl http2;
-    server_name your-domain.com;
-
-    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
-    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
-
-    # Frontend
-    location / {
-        proxy_pass http://localhost:3000;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-
-    # Frontend (serves UI and /admin/*)
-    location / {
-        proxy_pass http://localhost:3000;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-
-    # Backend API and protected resources
-    location /api {
-        proxy_pass http://localhost:3001;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-    location ~ ^/(photos|thumbnails|uploads) {
-        proxy_pass http://localhost:3001;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-}
-```
-
-Enable the site:
-```bash
-sudo ln -s /etc/nginx/sites-available/picpeak /etc/nginx/sites-enabled/
-sudo nginx -t
-sudo systemctl reload nginx
-```
-
-### Option 2: Traefik
-
-Add labels to `docker-compose.override.yml`:
-
-```yaml
-version: '3.8'
-
-services:
-  frontend:
-    labels:
-      - "traefik.enable=true"
-      - "traefik.http.routers.picpeak.rule=Host(`your-domain.com`)"
-      - "traefik.http.routers.picpeak.entrypoints=websecure"
-      - "traefik.http.routers.picpeak.tls.certresolver=letsencrypt"
-      - "traefik.http.services.picpeak.loadbalancer.server.port=80"
-
-  backend:
-    labels:
-      - "traefik.enable=true"
-      - "traefik.http.routers.picpeak-api.rule=Host(`your-domain.com`) && PathPrefix(`/api`)"
-      - "traefik.http.routers.picpeak-api.entrypoints=websecure"
-      - "traefik.http.routers.picpeak-api.tls.certresolver=letsencrypt"
-      - "traefik.http.services.picpeak-api.loadbalancer.server.port=3001"
-```
-
-### Option 3: Caddy
-
-Create a `Caddyfile`:
-
-```caddyfile
-your-domain.com {
-    # Frontend
-    handle /* {
-        reverse_proxy localhost:3000
-    }
-
-    # Backend API and admin
-    handle /api/* {
-        reverse_proxy localhost:3001
-    }
-    
-    handle /admin/* {
-        reverse_proxy localhost:3001
-    }
-
-    # Protected resources
-    handle /photos/* {
-        reverse_proxy localhost:3001
-    }
-
-    handle /thumbnails/* {
-        reverse_proxy localhost:3001
-    }
-
-    handle /uploads/* {
-        reverse_proxy localhost:3001
-    }
-}
-```
-
-### SSL Certificates
-
-For any reverse proxy, you can use Let's Encrypt:
-
-```bash
-# With Certbot

-
-# Or use your reverse proxy's built-in ACME support
-```
-
-## 🔧 Maintenance
-
-### Viewing Logs
-
-```bash
-# All services
-docker compose logs -f
-
-# Specific service
-docker compose logs -f backend
-docker compose logs -f frontend
-```
-
-### Backup
-
-#### Manual Backup
-```bash
-# Database backup
-docker exec picpeak-postgres pg_dump -U picpeak picpeak_prod > backup/db_$(date +%Y%m%d_%H%M%S).sql
-
-# Files backup
-tar -czf backup/photos_$(date +%Y%m%d_%H%M%S).tar.gz events/
-```
-
-#### Automated Backup
-The application includes a built-in backup service. Configure it in the admin panel:
-1. Login to admin panel
-2. Go to Settings → Backup
-3. Configure destination and schedule
-4. Enable backup service
-
-### Updates
-
-#### Method 1: Using Pre-built Images (Recommended)
-
-```bash
-# Pull latest changes (for configuration updates)
-git pull
-
-# Pull latest images from GitHub Container Registry
-docker compose -f docker-compose.production.yml pull
-
-# Restart with new images
-docker compose -f docker-compose.production.yml down
-docker compose -f docker-compose.production.yml up -d
-
-# Verify services are healthy
-docker compose -f docker-compose.production.yml ps
-```
-
-#### Method 2: Building from Source
-
-```bash
-# Pull latest changes
-git pull
-
-# Rebuild and restart
-docker compose down
-docker compose build --no-cache
-docker compose up -d
-
-# Verify services are healthy
-docker compose ps
-```
-
-#### Specific Version Updates
-
-To use a specific version of the images:
-
-```bash
-# Edit docker-compose.production.yml to specify version tags
-# Change: ghcr.io/the-luap/picpeak/backend:latest
-# To:     ghcr.io/the-luap/picpeak/backend:v1.0.0
-
-# Then pull and restart
-docker compose -f docker-compose.production.yml pull
-docker compose -f docker-compose.production.yml up -d
-```
-
-### Database Migrations
-
-Migrations run automatically on startup, but you can run them manually:
-
-```bash
-docker exec picpeak-backend npm run migrate
-```
-
-## 🚨 Troubleshooting
-
-### Common Issues
-
-#### 502 Bad Gateway / Login Failures
-**This is the most common deployment issue!** Usually caused by misconfigured URLs or network problems:
-
-1. **CORS Configuration Errors**:
-   ```bash
-   # WRONG - Missing port will cause CORS errors
-   FRONTEND_URL=http://10.0.252.12
-   
-   # CORRECT - Include the port you're accessing from
-   FRONTEND_URL=http://10.0.252.12:3000
-   ```
-   
-   The backend validates Origin headers against `FRONTEND_URL` for CORS. If they don't match exactly, you'll get 500 errors on login.
-
-2. **After Container Restarts**:
-   - Nginx may have cached old container IPs
-   - Solution: `docker restart picpeak-frontend`
-   - Always wait 30-60 seconds for health checks
-
-3. **Backend Not Starting After Migrations**:
-   - The logs may only show migrations completed
-   - Check if server is actually running: `docker exec picpeak-backend ps aux | grep node`
-   - Should see `node server.js` process
-
-4. **Login After Fresh Install**:
-   - Check backend logs for auto-generated admin password: `docker compose logs backend | grep "Admin password"`
-   - Email: `admin@example.com` (or your custom admin email from .env)
-   - Password: Auto-generated and shown in logs (e.g., `BraveTiger6231!`)
-   - Remember: Password MUST be changed on first login
-
-5. **Complete Fix Sequence**:
-   ```bash
-   # 1. Fix your .env file URLs
-   # 2. Full restart
-   docker-compose down
-   docker-compose up -d
-   
-   # 3. Wait for healthy status
-   sleep 60
-   docker ps  # All should show (healthy)
-   
-   # 4. Test backend directly
-   curl http://localhost:3001/health
-   
-   # 5. Test through frontend
-   curl http://localhost:3000/api/public/settings
-   ```
-
-#### Port Already in Use
-```bash
-# Check what's using the port
-sudo lsof -i :3000
-sudo lsof -i :3001
-
-# Change ports in .env
-FRONTEND_PORT=3002
-BACKEND_PORT=3003
-```
-
-#### Docker Compose Variable Substitution Errors
-If you see warnings like:
-```
-WARN[0000] The "fgbf" variable is not set. Defaulting to a blank string.
-```
-
-This means your password contains `$` which Docker Compose interprets as a variable. Solutions:
-1. **Best**: Generate passwords without `$`: `openssl rand -base64 32 | tr -d '$'`
-2. **Alternative**: Escape `$` as `$$` in your .env file
-3. **Example**: `DB_PASSWORD=Pass@#$$fgbf` instead of `DB_PASSWORD=Pass@#$fgbf`
-
-#### Permission Errors
-```bash
-# Fix ownership
-sudo chown -R 1000:1000 events data logs backup storage
-chmod -R 755 events data logs backup storage
-```
-
-#### Database Connection Issues
-```bash
-# Check if database is running
-docker compose ps
-docker compose logs postgres
-
-# Test connection
-docker exec picpeak-postgres pg_isready
-```
-
-#### Email Not Sending
-- Verify SMTP settings in .env
-- Check email queue: `docker exec picpeak-backend psql -U picpeak -d picpeak_prod -c "SELECT * FROM email_queue ORDER BY created_at DESC LIMIT 10;"`
-- For Gmail, use app-specific password
-- Check logs: `docker compose logs backend | grep email`
-
-### Health Checks
-
-```bash
-# Backend health
-curl http://localhost:3001/api/health
-
-# Frontend health
-curl http://localhost:3000
-
-# Database health
-docker exec picpeak-postgres pg_isready
-```
-
-### Useful Commands
-
-```bash
-# Enter backend container
-docker exec -it picpeak-backend sh
-
-# Enter database
-docker exec -it picpeak-postgres psql -U picpeak picpeak_prod
-
-# Reset admin password
-docker exec picpeak-backend node scripts/show-admin-credentials.js --reset
-
-# Check disk usage
-df -h
-du -sh events/ storage/ backup/
-
-# View running processes
-docker compose top
-```
-
-## Security Recommendations
-
-1. **Use HTTPS**: Always use a reverse proxy with SSL in production
-2. **Firewall**: Only expose necessary ports (80, 443)
-3. **Secure passwords**: Use strong, unique passwords for all services
-4. **Regular updates**: Keep Docker images and system packages updated
-5. **Backup strategy**: Set up automated backups and test restoration
-6. **Monitor logs**: Regularly check logs for suspicious activity
-7. **Rate limiting**: The app includes built-in rate limiting, configure as needed
-
-## Support

-git clone https://github.com/the-luap/picpeak.git
+git clone https://github.com/PicPeak/picpeak.git
 cd picpeak
 
-# Copy environment template
+# Copy the environment template — the defaults work out of the box.
+# Machine secrets (JWT, DB, Redis) are auto-generated on first run, and the
+# admin account is created in the browser (see below). Edit .env only to

 cp .env.example .env
 
-# Edit configuration (required: JWT_SECRET)
-nano .env
-
 # Start with Docker Compose
-docker-compose up -d
+docker compose up -d
 
-# Access at http://localhost:3005
+# Access at http://localhost:3000
 ```
 
-Note on Docker file permissions (PUID/PGID)
-- When using bind mounts (e.g., `./storage`, `./data`, `./logs`, `./events`), ensure the container user can write to these host folders. The backend runs as a non‑root user by default.
-- Set `PUID` and `PGID` in your `.env` to match your host user’s UID/GID (run `id -u` and `id -g` on the host). Compose maps the container user to these values.
-- Example in `.env`:
-  - `PUID=1000`
-  - `PGID=1000`
-- Without this, creating events, uploads, thumbnails, or logs can fail with “Permission denied”.
+### First run — create your admin account
+
+On first start with no `ADMIN_PASSWORD` set, PicPeak has **no admin account yet** and greets you with an in-browser setup screen — no credentials in `.env`:
+
+1. Open **http://localhost:3000/admin** — you'll be redirected to `/setup`.
+2. Grab the **one-time setup token** from the backend logs (it's also saved to `data/SETUP_TOKEN`):
+   ```bash
+   docker compose logs backend | grep -i "setup token"
+   ```
+3. Paste the token, set your admin **email + password**, and you're in. The token is single-use, and the setup screen closes permanently once an admin exists.
+
+> Prefer the old behaviour? Set `ADMIN_PASSWORD` in `.env` and PicPeak auto-creates the admin on first boot instead (credentials written to `data/ADMIN_CREDENTIALS.txt`).
+
+Note on Docker file permissions
+- The backend container starts as root, chowns bind-mounted host directories (`./storage`, `./data`, `./logs`) to UID 1001 (`nodejs`), then drops privileges via `su-exec` before running the app. No host-side setup needed for fresh installs.
+- If you pin `user:` in a compose override (e.g. to map a specific host UID), the self-chown is skipped and you must pre-chown the host directories to that UID — see [docs.picpeak.app/deployment/docker#permissions](https://docs.picpeak.app/deployment/docker#permissions).
+
+**ARM64 (aarch64) systems:** Pre-built images include native `linux/arm64`, no platform flags or emulation needed. If you're on an older image tag that's still amd64-only, see [docker-compose.amd64.override.yml](docker-compose.amd64.override.yml) for a transitional fallback.
+
+## 🔄 Release Channels
+
+PicPeak offers two release channels for different needs. Stable promotions are cut from a known-good beta point every 4–6 weeks — see [RELEASING.md](RELEASING.md) for the maintainer's promotion criteria and cadence policy.
+
+### Stable Channel (Recommended)
+- Production-ready releases
+- Thoroughly tested before release
+- Docker tags: `stable`, `latest`, or specific version like `v2.3.0`
+
+### Beta Channel
+- Early access to new features
+- May contain bugs or incomplete functionality
+- Docker tags: `beta` or specific version like `v2.3.0-beta.1`
+
+### Switching Channels
+
+Set the `PICPEAK_CHANNEL` environment variable in your `.env` file:
+
+```bash
+# For stable releases (default)
+PICPEAK_CHANNEL=stable
+
+# For beta releases
+PICPEAK_CHANNEL=beta
+
+# For a specific version
+PICPEAK_CHANNEL=v2.3.0
+```
+
+Then update your containers:
+
+```bash
+docker compose -f docker-compose.production.yml pull
+docker compose -f docker-compose.production.yml up -d
+```
+
+### Update Notifications
+
+The admin dashboard automatically notifies you when updates are available for your channel. To disable update checks, set:
+
+```bash
+UPDATE_CHECK_ENABLED=false
+```

+## 💾 Storage Backends
+
+PicPeak supports two storage backends for photos, thumbnails, hero images, watermarks, and archive zips. Both are configured via environment variables; no code change is required to switch.
+
+| Capability | `STORAGE_BACKEND=local` (default) | `STORAGE_BACKEND=s3` |
+|---|---|---|
+| Photo / thumbnail / hero storage | Local filesystem under `STORAGE_PATH` | Bucket on any S3-compatible service |
+| Admin UI upload | ✅ | ✅ |
+| Filesystem auto-import (chokidar watcher) | ✅ | ❌ — disabled (use the upload API) |
+| Watermarks, fingerprinting, fragmentation | ✅ | ✅ (materialized to a tmp file just-in-time) |
+| Bulk download zips (cached + on-the-fly) | ✅ | ✅ |
+| Backups | ✅ | ✅ |
+| External media reference mode (`EXTERNAL_MEDIA_ROOT`) | ✅ (always local) | ✅ (still local — not migrated) |
+
+### Switching to an S3-compatible backend
+
+1. Provision a bucket and credentials. The minimum IAM policy is documented in `.env.example`.
+2. Set `STORAGE_BACKEND=s3` plus `STORAGE_S3_BUCKET`, `STORAGE_S3_REGION`, `STORAGE_S3_ACCESS_KEY`, `STORAGE_S3_SECRET_KEY`. For non-AWS providers (MinIO, R2, B2, …) also set `STORAGE_S3_ENDPOINT`.
+3. If you have existing local content, copy it first: `node backend/scripts/migrate-storage.js --dry-run` then `node backend/scripts/migrate-storage.js`. The script is idempotent and writes a failures CSV.
+4. Restart the backend. The startup check pings the bucket and refuses to boot on misconfig.
+
+Note: presigned-URL serving (zero-bandwidth direct downloads from S3) is intentionally **not** in v1 — every request still streams through the backend so watermarks, devtools-detection, and access logging keep working.
+
+## 🔔 Webhooks
+
+PicPeak POSTs event/photo lifecycle notifications to URLs you configure under **Settings → Webhooks**. Each delivery is signed `HMAC-SHA256` with a per-webhook secret in the `X-PicPeak-Signature` header so receivers can verify the request really came from your PicPeak instance.
+
+### Event types
+
+| Event | Fires when |
+|---|---|
+| `event.created` | Gallery created (admin or API) |
+| `event.published` | Draft becomes live (`is_draft: true → false`) — also fires when an event is created with `is_draft=false` |
+| `event.archived` | Bulk-archive, manual archive, or auto-archive on expiry |
+| `event.expired` | Expiration checker marks the gallery inactive (fires before `event.archived` in the cascade) |
+| `photo.uploaded` | Admin upload, API upload, guest upload, or auto-import |
+| `photo.deleted` | Single delete, bulk delete (NOT fired per-photo when an event is archived — receivers infer from `event.archived` to avoid flooding) |
+
+### Payload shape
+
+```json
+{
+  "id": "delivery-uuid",
+  "type": "event.published",
+  "created_at": "2026-04-28T05:25:00.000Z",
+  "data": {
+    "event": { "id": 123, "slug": "wedding-smith", "share_url": "https://..." }
+  }
+}
+```
+
+Also sent on every request:
+- `X-PicPeak-Signature` — `HMAC-SHA256(secret, raw_body)` as hex
+- `X-PicPeak-Event` — the event type (handy for routing without parsing the body)
+- `X-PicPeak-Delivery` — UUID for idempotency on the receiver side
+- `User-Agent: PicPeak-Webhooks/1.0`
+
+### Verifying signatures
+
+**Node.js**
+```js
+const crypto = require('crypto');
+function verify(secret, rawBody, signature) {
+  const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
+  const a = Buffer.from(expected, 'hex');
+  const b = Buffer.from(signature, 'hex');
+  if (a.length !== b.length) return false;
+  return crypto.timingSafeEqual(a, b);
+}
+```
+
+**Python**
+```python
+import hmac, hashlib
+def verify(secret: str, raw_body: bytes, signature: str) -> bool:
+    expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest()
+    return hmac.compare_digest(expected, signature)
+```
+
+**curl + openssl** (one-liner for a quick replay)
+```sh
+SIG=$(printf '%s' "$BODY" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
+[ "$SIG" = "$RECEIVED_SIG" ] && echo OK || echo MISMATCH
+```
+
+### Retries + observability
+
+- `2xx` → success, recorded with latency
+- Non-`2xx` or network error → exponential backoff: `1m → 5m → 30m → 2h → 12h`, max 5 attempts
+- After max attempts: status `failed`, surfaces in **Settings → Webhooks → Deliveries** with a "Replay" button
+- Up to 5 deliveries in flight at once; one slow consumer can't block others (configurable via `WEBHOOK_DELIVERY_CONCURRENCY`)
+- Response body truncated to 1KB before storage so chatty receivers don't bloat the audit log
+
+The deliveries page (`/admin/webhooks/:id/deliveries`) shows every attempt with timestamp, status, HTTP code, latency, payload sent, signature, and response. Click "Send test event" to fire a synthetic delivery for any event type.
+
+### SSRF protection
+
+Webhook URLs are validated against the same private-IP blocklist used elsewhere in the app — loopback, private RFC1918 ranges, link-local, `.local`/`.internal` hostnames, cloud metadata endpoints. The check runs both at create time and per-delivery (DNS-rebinding mitigation).
+
+For local development with a receiver on the same machine or docker network, set `WEBHOOK_ALLOW_PRIVATE_URLS=true`. Production deployments must leave this OFF.
+
 ## 💻 System Requirements
 
 ### Minimum Requirements
 - **CPU**: 2 CPU cores
-- **RAM**: 2GB minimum
+- **RAM**: **4 GB minimum** for a normal photo-upload workload — sharp/libvips
+  decodes the full uncompressed frame before resize, and the default two
+  worker loops at sharp-concurrency 2 can push peak RSS past 1.5 GB on a
+  batch of 20-MP+ photos. On a 2 GB VPS that's enough to OOM-kill the
+  backend mid-batch (surfaces as 503s on thumbnails — see [Low-memory
+  hosts](#low-memory-hosts) below for the recipe to run on 2 GB).
 - **Storage**: 20GB minimum (plus photo storage needs)
 - **OS**: Linux (Ubuntu 20.04+), macOS, or Windows with WSL2
 - **Node.js**: v18.0.0 or higher
@@ -133,6 +338,51 @@ Perfect for:
 - **Docker**: v20.10.0+
 - **Docker Compose**: v2.0.0+
 
+### Low-memory hosts
+
+Running on 2 GB RAM (e.g. an entry-level VPS) is workable but requires
+tuning the upload-processor concurrency down. The backend auto-detects
+total RAM at startup via `os.totalmem()` — on a host that reports < 3 GB,
+it defaults `UPLOAD_PROCESSOR_CONCURRENCY` to **1** instead of 2 and logs
+a one-shot warning. You can pin the value explicitly in `.env`:
+
+```env
+# Single worker loop — slower batch processing, lower peak RSS
+UPLOAD_PROCESSOR_CONCURRENCY=1
+```
+
+The trade-off is throughput: a single worker processes one photo at a
+time, so a 100-photo batch takes ~2× as long but won't OOM. **Health-check
+note**: if the backend dies under memory pressure, the gallery serves
+`503 Service Unavailable` on thumbnails until Docker's
+`restart: unless-stopped` brings the container back. Persistent 503s
+during/after an upload batch on a low-memory host are almost always this.
+
+### Video Support Requirements
+When enabling video uploads, consider these additional resources:
+
+| Resource | Recommendation | Notes |
+|----------|----------------|-------|
+| **RAM** | 4GB+ recommended | FFmpeg processing requires more memory |
+| **Storage** | Plan for 10-100x more | Videos are significantly larger than images |
+| **CPU** | Additional cores help | Video thumbnail extraction is CPU-intensive |
+| **Bandwidth** | Higher throughput | Video streaming requires more bandwidth |
+
+**Technical Notes:**
+- FFmpeg is bundled via npm (`@ffmpeg-installer/ffmpeg`) - no system installation required
+- Maximum upload size: **10GB per video file**
+- Chunked upload support for files >100MB (resumable uploads)
+- Supported formats: MP4, WebM, MOV, AVI
+- Video thumbnails are automatically generated from the first few seconds
+
+**For Nginx/Reverse Proxy:**
+If using Nginx, increase the client max body size:
+```nginx
+client_max_body_size 10G;
+proxy_read_timeout 3600;
+proxy_send_timeout 3600;
+```

 PicPeak is inspired by the best features of commercial platforms while remaining completely open source. Special thanks to all contributors who make this project possible.
 
+### 👥 Contributors
+
+A huge thank you to the people whose code, reports, and feedback have shaped PicPeak:
+
+- [**@the-luap**](https://github.com/the-luap) — creator and lead maintainer. Started the project and built PicPeak's foundation and the entire gallery experience (events, galleries, uploads, sharing, download protection, templates), plus backup & restore, analytics, system health, branding/theming, and WhatsApp notifications — and the architecture every later feature builds on.
+- [**@Luca-Timo**](https://github.com/Luca-Timo) — native Apple Silicon multi-arch images, external-URL toggle for legal CMS pages, the lazy-loaded folder tree picker, the admin-email picker on event creation, the data-driven self-hosted webfont system, the gallery header/banner decoupling, several typed-API refactors, and the CRM + accounting suite (quotes/contracts/invoices, hours logging, calendar, tax report, inbound supplier-invoice capture, expenses, and the Treuhänder/Banana export). Consistently raises the bar with thoughtful PRs.
+- [**@Rekoo-PS**](https://github.com/Rekoo-PS) — sharp-eyed bug reporter and product feedback. Filed the issues that drove the login-loop fix, the gallery-loading skeleton work, the redirection cleanup, the mobile-lightbox overhaul, the admin-events search-counter fix, the photo-count column, and the bulk-delete workflow. Also a [BuyMeACoffee](https://buymeacoffee.com/theluap) supporter — the kind of feedback loop that keeps the project useful for real deployments.

RELEASING.md

+# Release Process
+
+This document describes how PicPeak releases are cut. It's the maintainer's reference, not user documentation — for the user-facing channel choice (stable vs pre-release) see the [Release Channels section in README.md](README.md#-release-channels).
+
+## TL;DR
+
+- **`main` branch** receives all merged work (active development). Every push triggers a `release-please` PR that proposes the next `vX.Y.Z-beta.N` pre-release. Merging that PR tags the pre-release and publishes Docker images under the `:main` rolling tag + the version-specific tag.
+- **`stable` branch** holds the curated stable channel. Stable releases are cut from a known-good `main` point via a `release/X.Y.Z-merge-from-main` branch and a manual PR to `stable`. Merging that PR triggers `release-please` to propose the stable release.
+- Target cadence: **a stable release every 4–6 weeks**, or sooner if `main` has been quiet and ready for promotion.
+
+> **Branch model background** — `main` (active dev) was previously called `beta`, and `stable` (curated channel) was previously called `main`. The rename happened with #669 to match the convention every other open-source project uses. The mechanics below all reference the post-rename names.
+
+## Cadence target
+
+4–6 weeks between stable releases is the working target. Reasoning:
+
+- Long enough that each stable carries meaningful changes worth the upgrade burden.
+- Short enough that pre-release users aren't carrying the "real" project alone for months — the stable channel should actually be usable as the recommended channel for new installs.
+- Aligns with how release-please surfaces pre-releases (multiple pre-release points usually accumulate inside a 4–6 week window, which gives natural promotion candidates).
+
+This is a target, not a hard rule. Cut sooner if `main` has been quiet and stable longer than usual. Cut later if `main` is in flux for security or migration reasons.
+
+## Promotion criteria
+
+A `main` tip is eligible for promotion to `stable` when **all** of the following hold:
+
+1. **CI green on the candidate `main` tip.** Specifically: `schema-drift` (`upgrade-from-bootstrap`), `fresh-install`, `Tests` (backend Jest + frontend Vitest), the four `Build and Push Docker Images` arch matrices, and `GitGuardian Security Checks`.
+2. **No open `bug`-labelled issues against the candidate for at least 7 days.** Issues fixed-but-not-yet-closed count as fixed; verify their PR is in the candidate `main` tip before closing them out.
+3. **An upgrade walk has been done on real production-shaped data** — apply the candidate's migration chain to a snapshot of the previous stable's DB and verify no manual intervention is required. CI proves fresh-install works; the upgrade walk is what proves the upgrade path works.
+4. **Operator-time smoke** on the candidate: log in, create event, upload photos, share gallery, open as a customer, log out. Catches binary-incompatibility regressions and UI-level breaks that unit tests don't see.
+
+If any of the four fail, the promotion waits. File any blockers as `bug`-labelled issues and let them bake on `main` before re-evaluating.
+
+## How a stable release is cut
+
+The actual mechanics, in order:
+
+1. **Pick the `main` tip.** Confirm it satisfies the four promotion criteria above. Note the exact SHA — that's what you're promoting.
+
+2. **Create the release branch from the `main` tip.**
+   ```bash
+   git push origin <main-tip-sha>:refs/heads/release/X.Y.Z-merge-from-main
+   ```
+   Naming convention: `release/X.Y.Z-merge-from-main`, where `X.Y.Z` is the stable version you intend to land. release-please will write the actual `X.Y.Z` on merge — the branch name is just a human label.
+
+3. **Open a PR to `stable`.** Title: `chore(release): promote main → stable as vX.Y.Z`. Body should summarise the major themes since the previous stable, the migration count, and any operator notes (e.g. "this release adds 22 migrations; existing installs should snapshot before upgrading"). See PR #568 as a worked example (predates the rename; the mechanics are unchanged).
+
+4. **Resolve conflicts.** `stable` almost always has commits `main` doesn't (security backports, release-please's stable-channel release commits, README rewrites). For each conflicting file, decide deliberately:
+   - **`backend/package.json` / `package-lock.json` + `frontend/package.json` / `package-lock.json`** — usually take `main`'s version (superset), but verify any security-pinned deps (`axios`, `nodemailer`, `i18next-http-backend`, `multer`, `tar`) on `main` are `>=` the pinned versions on `stable`. If `stable` has a newer pinned version (e.g. an emergency CVE backport `main` hasn't picked up), take `stable`'s pin.
+   - **`README.md`** — keep `stable`'s version if it has had a recent rewrite that `main` didn't pick up; otherwise take `main`'s.
+   - **`CHANGELOG.md`** — keep `stable`'s; release-please regenerates entries on its next stable cut from the commits going forward.
+   - **`.release-please-manifest.json`** — keep `stable`'s; release-please owns this file.
+   - Any other auto-merged file — spot-check that the auto-merge produced something sensible, especially for security-sensitive files (`backend/src/middleware/`, `backend/src/utils/tokenUtils.js`).
+
+5. **Wait for CI on the PR.** All ten checks (the original eight plus `merge-backend` and `merge-frontend`) must be green. If anything fails, fix on the release branch (NOT on `main` — `main` has already moved on).
+
+6. **Merge.** Standard merge commit, not squash — the PR's history (the individual feature commits) carries forward into `stable`'s log.
+
+7. **release-please picks it up.** Within minutes, release-please will open a new `chore(stable): release X.Y.Z` PR proposing the stable release. Review the auto-generated CHANGELOG.md entries for accuracy, edit if needed, and merge. That merge creates the `vX.Y.Z` git tag, publishes Docker images on the `:stable` and `:latest` tags, and creates the GitHub Release page.
+
+8. **Close the loop.** Bulk-close any `bug` issues that were fixed-but-not-closed and now appear in the released changelog. Reference the merge commit so reporters know which version contains the fix.
+
+## Hotfix path (backport to current stable)
+
+If a critical bug or security issue affects the current stable and `main` has moved too far for a full promotion to be appropriate, backport just the fix:
+
+1. Create a `security/cve-backport-X.Y.Z` or `fix/critical-X.Y.Z` branch off `stable`.
+2. Cherry-pick or hand-write the minimal fix.
+3. Open a PR to `stable` with the smallest possible diff.
+4. After merge, release-please will propose a patch-level stable release (e.g. `v3.55.1`).
+5. **Forward-port the fix to `main`** if it isn't already there. Otherwise the next full promotion will reintroduce the bug.
+
+PR #412 ("backport 18 dependency CVE patches from beta") is a worked example of this path (predates the rename; the mechanics are unchanged).
+
+## Versioning
+
+PicPeak follows [Semantic Versioning](https://semver.org/) with one project-specific convention:
+
+- **MAJOR** bumps are reserved for breaking schema changes that require operator action on upgrade (e.g. a migration that's not safe to auto-apply, an env-var rename that can't be auto-detected).
+- **MINOR** bumps for new features, additive schema changes, and any change to the public HTTP API surface.
+- **PATCH** bumps for bug fixes and operator-invisible internal changes.
+- **Pre-release suffix** (`-beta.N`) for every `main`-channel cut; the `N` counter resets on each new MINOR or MAJOR target. The suffix kept the historical `-beta` literal even after the branch rename — operators were already pinning to `v3.x.y-beta.N` and changing the literal would have broken those pins.
+
+release-please derives all of this from conventional commit prefixes (`feat:`, `fix:`, `BREAKING CHANGE:`, etc.) automatically.
+
+## Things that don't go through this process
+
+- **Documentation-only changes** can land on either `stable` or `main` directly (no release cut needed); release-please will pick them up on the next regular release.
+- **Test-only changes** — same.
+- **CI / workflow changes** — same, but be aware they take effect on the branch they land on, so a CI fix targeting `main` won't fix a broken stable-channel workflow until the next promotion.
+
+## When this doc is wrong
+
+If you find yourself working around something here, update the doc before doing the workaround. The point of a written process is that future-you doesn't have to remember the workaround.

+
+#### Adding Photos via File System
+
+> **Important:** You must first create the event in the admin panel. The file watcher only detects new photos for events that already exist in the database. You cannot create a gallery by copying files alone.
+
+Once an event exists, you can add photos by copying them into the event's folder. PicPeak's built-in file watcher will automatically detect the new files, create database records, and generate thumbnails.
 
-#### Method 2: File System
 ```bash
-# Docker installation
-mkdir -p ~/picpeak/storage/events/active/wedding-smith-2024
-cp /path/to/photos/* ~/picpeak/storage/events/active/wedding-smith-2024/
+# Docker installation — copy photos into an existing event's folder

+sudo cp /path/to/photos/*.jpg /opt/picpeak/events/active/<event-slug>/
+sudo chown -R picpeak:picpeak /opt/picpeak/events/active/<event-slug>
 ```
 
+The event slug is visible in the admin panel URL or share link (e.g. `wedding-smith-2024`). Supported formats: `.jpg`, `.jpeg`, `.png`, `.webp`. The file watcher has a 2-second stability delay before processing new files.

+#   true   - always set Secure (HTTPS-only cookies; breaks plain-HTTP access —
+#            login appears to succeed but the browser silently drops the
+#            cookie, leaving you in a redirect loop. Only set this if you
+#            ALWAYS reach the site via HTTPS)
+#   false  - never set Secure (allows HTTP; cookies not protected on HTTPS)
+#   auto   - decide per request: Secure on HTTPS, not on HTTP. Reads
+#            req.secure from Express which respects X-Forwarded-Proto from a
+#            trusted reverse proxy. This is the default and is the right
+#            choice for most deployments.
+#
+# Why 'auto' is the default in production:
+#   - On real HTTPS (reverse proxy with X-Forwarded-Proto), req.secure is
+#     true → Secure flag is still emitted. No security regression vs. true.
+#   - On plain HTTP (LAN access, first-time install before reverse proxy is
+#     wired up), req.secure is false → Secure flag is omitted → login works
+#     instead of silently looping back to /admin/login.
+#
+# When you'd set this explicitly:
+#   - COOKIE_SECURE=true → strict HTTPS-only deployments where you want
+#     defense in depth against accidentally serving over HTTP.
+#   - COOKIE_SECURE=false → you intentionally only ever serve over HTTP and
+#     don't want the per-request check (rare).
+#
+# Requirements for 'auto' mode to detect HTTPS correctly:
+#   1. Your reverse proxy MUST send X-Forwarded-Proto: https on HTTPS
+#      requests. Standard configs for NPM/Traefik/Caddy do this by default.
+#   2. The proxy must be on a trusted IP range. By default PicPeak trusts
+#      loopback and private networks (127.0.0.1, 10.x, 172.16-31.x,
+#      192.168.x, link-local). Proxies outside those ranges need custom
+#      trust proxy configuration.
+# COOKIE_SECURE=auto

+/**
+ * Pins the fix for the PR #596 review blocker.
+ *
+ * **The bug**
+ *
+ *   `preservedMeta` was declared with `let` INSIDE the PostgreSQL
+ *   `else` branch of `performDatabaseRestore`, then read AFTER the
+ *   `else` block closed at the shared replay site (~L1030). On every
+ *   real PG restore:
+ *
+ *     ReferenceError: preservedMeta is not defined
+ *
+ *   would fire — psql had already completed the data restore, but
+ *   the operator-meta replay never ran, the trigger file was left
+ *   in place by `_installFromBackupBoot.js` because the restore
+ *   "failed", and `combined.log` got a loud FAILED line even though
+ *   the data was back. Caught on PR #596 review by the maintainer.
+ *
+ * **Why CI missed it**
+ *
+ *   The integration tests around `performFullRestore` only exercise
+ *   the SQLite branch via `this.dbType === 'sqlite'`. The PG branch
+ *   (~L827-984) requires a real PG connection + real `psql` binary,
+ *   neither of which are in the test environment. So the scope leak
+ *   sat untested until the maintainer ran a real DR cycle.
+ *
+ * **What this test does**
+ *
+ *   Reads the source of `restoreService.js` and asserts the scope
+ *   contract: the `preservedMeta` declaration sits ABOVE the
+ *   SQLite/PG branch split, so the replay block at the bottom of the
+ *   try{} can read it on either branch.
+ *
+ *   Source-inspection is uglier than a runtime test but it has two
+ *   advantages here: (a) it doesn't require a real PG cluster + psql
+ *   binary in CI, (b) it pins the EXACT contract — "the declaration
+ *   must be visible to the replay block" — which is the property
+ *   that broke, more directly than a runtime test would.
+ *
+ *   The follow-up "real-PG integration test in CI" (separate task)
+ *   would replace this with an end-to-end exercise, at which point
+ *   this can be deleted.

+ * Regression test for GHSA-4j34-x562-5vfq — broken access control in the legacy
+ * /api/events router.
+ *
+ * The legacy router exposed create/list/update/delete/extend guarded by
+ * adminAuth ALONE (no requirePermission, no requireEventOwnership), so any
+ * back-office account — down to a read-only viewer — could read every gallery's
+ * password_hash/share_token and take over any gallery. The fix removes that
+ * router entirely and migrates its one UI-used route (POST /:id/extend) to the
+ * canonical /api/admin/events mount, where it inherits the permission +
+ * ownership guards.
+ *
+ * This test pins two invariants:
+ *   1. The legacy source file is gone (nothing can re-mount it).
+ *   2. The migrated extend route enforces ownership — a non-owning editor gets
+ *      403, the owner succeeds.
