+
+**First Run:**
+1. Visit `http://localhost:3000` (or your configured domain)
+2. Complete the first-run wizard to create your admin account
+3. Configure applications and invite users
+
+**Upgrading:**
+
+```bash
+# Pull latest image
+docker compose pull
+
+# Restart with new image (migrations run automatically)
+docker compose up -d
+```

+
+```bash
+# View logs
+docker compose logs -f clinch
+
+# View last 100 lines
+docker compose logs --tail=100 clinch
+```
+
+### Backup & Restore
+
+Clinch stores all persistent data in the `storage/` directory (or `/rails/storage` in Docker):
+- SQLite database (`production.sqlite3`)
+- Uploaded files via ActiveStorage (application icons)
+
+**Database Backup:**
+
+Use SQLite's `VACUUM INTO` command for safe, atomic backups of a running database:
+
+```bash
+# Local development
+sqlite3 storage/production.sqlite3 "VACUUM INTO 'backup.sqlite3';"
+```
+
+This creates an optimized copy of the database that's safe to make even while Clinch is running.
+
+**Full Backup (Database + Uploads):**
+
+For complete backups including uploaded files, backup the database and uploads separately:
+
+```bash
+# 1. Backup database (safe while running)
+sqlite3 storage/production.sqlite3 "VACUUM INTO 'backup-$(date +%Y%m%d).sqlite3';"
+
+# 2. Backup uploaded files (ActiveStorage files are immutable)
+tar -czf uploads-backup-$(date +%Y%m%d).tar.gz storage/uploads/
+
+# Docker Compose equivalent
+docker compose exec clinch sqlite3 /rails/storage/production.sqlite3 "VACUUM INTO '/rails/storage/backup-$(date +%Y%m%d).sqlite3';"
+docker compose exec clinch tar -czf /rails/storage/uploads-backup-$(date +%Y%m%d).tar.gz /rails/storage/uploads/
+```
+
+**Restore:**
+
+```bash
+# Stop Clinch first
+# Then restore database
+cp backup-YYYYMMDD.sqlite3 storage/production.sqlite3
+
+# Restore uploads
+tar -xzf uploads-backup-YYYYMMDD.tar.gz -C storage/
+```
+
+**Docker Volume Backup:**
+
+**Option 1: While Running (Online Backup)**
+
+a) **Mapped volumes** (recommended, e.g., `-v /host/path:/rails/storage`):
+```bash
+# Database backup (safe while running)
+sqlite3 /host/path/production.sqlite3 "VACUUM INTO '/host/path/backup-$(date +%Y%m%d).sqlite3';"
+
+# Then sync to off-server storage
+rsync -av /host/path/backup-*.sqlite3 /host/path/uploads/ remote:/backups/clinch/
+```
+
+b) **Docker volumes** (e.g., using named volumes in compose):
+```bash
+# Database backup (safe while running)
+docker compose exec clinch sqlite3 /rails/storage/production.sqlite3 "VACUUM INTO '/rails/storage/backup.sqlite3';"
+
+# Copy out of container
+docker compose cp clinch:/rails/storage/backup.sqlite3 ./backup-$(date +%Y%m%d).sqlite3
+```
+
+**Option 2: While Stopped (Offline Backup)**
+
+If Docker is stopped, you can copy the entire storage:
+```bash
+docker compose down
+
+# For mapped volumes
+tar -czf clinch-backup-$(date +%Y%m%d).tar.gz /host/path/
+
+# For docker volumes
+docker run --rm -v clinch_storage:/data -v $(pwd):/backup ubuntu \
+  tar czf /backup/clinch-backup-$(date +%Y%m%d).tar.gz /data
+
+docker compose up -d
+```
+
+**Important:** Do not use tar/snapshots on a running database - use `VACUUM INTO` instead or stop the container first.
+

-## Three Options Explained (Very Brief)
-
-### Option A: Keep Your Implementation
- **Time:** Ongoing (add features incrementally)
- **Effort:** 4-6 months to reach feature parity
- **Maintenance:** 8-10 hours/month
- **Best if:** Auth Code + PKCE is sufficient forever
-
-### Option B: Switch to Rodauth-OAuth
- **Time:** 5-9 weeks (one-time migration)
- **Learning:** 1-2 weeks (Roda framework)
- **Maintenance:** 1-2 hours/month
- **Best if:** Need enterprise features, want low maintenance
-
-### Option C: Hybrid Approach (Microservices)
- **Time:** 3-5 weeks (independent setup)
- **Learning:** Low (Roda is isolated)
- **Maintenance:** 2-3 hours/month
- **Best if:** Want Option B benefits without full Rails→Roda migration

-
-## Key Findings
-
-**What Rodauth-OAuth Provides That You Don't Have:**
- Refresh tokens
- Token revocation (RFC 7009)
- Token introspection (RFC 7662)
- Client Credentials grant (machine-to-machine)
- Device Code flow (IoT/smart TV)
- JWT Access Tokens (stateless)
- Session Management
- Front & Back-Channel Logout
- Token hashing (bcrypt security)
- DPoP support (token binding)
- TLS mutual authentication
- Dynamic Client Registration
- 20+ more optional features
-
-**Security Differences:**
- Your impl: Tokens stored in plaintext (DB breach = token theft)
- Rodauth: Tokens hashed with bcrypt (secure even if DB breached)
-
-**Maintenance Burden:**
- Your impl: YOU maintain everything
- Rodauth: Community maintains, you maintain config only

-# Rodauth-OAuth Decision Guide
-
-## TL;DR - Make Your Choice Here
-
-### Option A: Keep Your Rails Implementation
-**Best if:** Authorization Code + PKCE is all you need, forever
- Keep your current 450 lines of OIDC controller code
- Maintain incrementally as needs change
- Stay 100% in Rails ecosystem
- Time investment: Ongoing (2-3 months to feature parity)
- Learning curve: None (already know Rails)
-
-### Option B: Switch to Rodauth-OAuth
-**Best if:** You need enterprise features, standards compliance, low maintenance
- Replace 450 lines with plugin config
- Get 34 optional features on demand
- OpenID Certified, production-hardened
- Time investment: 4-8 weeks (one-time)
- Learning curve: Medium (learn Roda/Rodauth)
-
-### Option C: Hybrid (Recommended if Option B appeals you)
-**Best if:** You want rodauth-oauth benefits without framework change
- Run Rodauth-OAuth as separate microservice
- Keep your Rails app unchanged
- Services talk via HTTP APIs
- Time investment: 2-3 weeks (independent services)
- Learning curve: Low (Roda is isolated)

-## Real-World Questions to Ask Your Team
-
-### Question 1: Feature Needs
- "Do we need refresh tokens?"
- "Will clients ask for token revocation?"
- "Do we support service-to-service auth (client credentials)?"
- "Will we ever need device code flow (IoT)?"
-
-If YES to any: **Option B or C makes sense**
-
-### Question 2: Maintenance Philosophy
- "Do we want to own the OAuth code?"
- "Can we afford to maintain OAuth compliance?"
- "Do we have experts in OAuth/OIDC?"
-
-If NO to all: **Option B or C is better**
-
-### Question 3: Framework Flexibility
- "Is Rails non-negotiable for this company?"
- "Can our team learn a new framework?"
- "Can we run microservices?"
-
-If Rails is required: **Option C (hybrid)**
-
-### Question 4: Time Constraints
- "Do we have 4-8 weeks for a migration?"
- "Can we maintain OAuth for years?"
- "What if specs change?"
-
-If time-constrained: **Option B is fastest path to full features**
-

-# Rodauth-OAuth Analysis: Comprehensive Comparison with Clinch's Custom Implementation
-
-## Executive Summary
-
-**Rodauth-OAuth** is a production-ready Ruby gem that implements the OAuth 2.0 framework and OpenID Connect on top of the `rodauth` authentication library. It's architected as a modular feature-based system that integrates with Roda (a routing library) and provides extensive OAuth/OIDC capabilities.
-
-Your current Clinch implementation is a **custom, minimalist Rails-based OIDC provider** focusing on the authorization code grant with PKCE support. Switching to rodauth-oauth would provide significantly more features and standards compliance but requires architectural changes.
-
---
-
-## 1. What Rodauth-OAuth Is
-
-### Core Identity
- **Type**: Ruby gem providing OAuth 2.0 & OpenID Connect implementation
- **Framework**: Built on top of `rodauth` (a dedicated authentication library)
- **Web Framework**: Designed for Roda framework (lightweight, routing-focused)
- **Rails Support**: Available via `rodauth-rails` wrapper
- **Maturity**: Production-ready, OpenID-Certified for multiple profiles
- **Author**: Tiago Cardoso (tiago.cardoso@gmail.com)
- **License**: Apache 2.0
-
-### Architecture Philosophy
- **Feature-based**: Modular "features" that can be enabled/disabled
- **Database-agnostic**: Uses Sequel ORM, works with any SQL database
- **Highly configurable**: Override methods to customize behavior
- **Standards-focused**: Implements RFCs and OpenID specs strictly

-## 4. Architecture: How It Works
-
-### As a Plugin System
-
-Rodauth-OAuth integrates with Roda as a **plugin**:
-
-```ruby
-# This is how you configure it
-class AuthServer < Roda
-  plugin :rodauth do
-    db database_connection
-    
-    # Enable features
-    enable :login, :logout, :create_account, :oidc, :oidc_session_management,
-           :oauth_pkce, :oauth_authorization_code_grant
-    
-    # Configure
-    oauth_application_scopes %w[openid email profile]
-    oauth_require_pkce true
-    hmac_secret "SECRET"
-    
-    # Customize with blocks
-    oauth_jwt_keys("RS256" => [private_key])
-    oauth_jwt_public_keys("RS256" => [public_key])
-  end
-end
-```
-
-### Request Flow Architecture
-
-```
-1. Authorization Request
-   ↓
-   rodauth validates params
-   ↓
-   (if not auth'd) user logs in via rodauth
-   ↓
-   (if first use) consent page rendered
-   ↓
-   create oauth_grant (code, nonce, PKCE challenge, etc.)
-   ↓
-   redirect with auth code
-
-2. Token Exchange
-   ↓
-   rodauth validates client (Basic/POST auth)
-   ↓
-   validates code, redirect_uri, PKCE verifier
-   ↓
-   creates access token (plain or JWT)
-   ↓
-   creates refresh token
-   ↓
-   returns JSON with tokens
-
-3. UserInfo
-   ↓
-   validate access token
-   ↓
-   lookup grant/account
-   ↓
-   return claims as JSON
-```
-
-### Feature Composition
-
-Features depend on each other. For example:
- `oidc` depends on: `active_sessions`, `oauth_jwt`, `oauth_jwt_jwks`, `oauth_authorization_code_grant`, `oauth_implicit_grant`
- `oauth_pkce` depends on: `oauth_authorization_code_grant`
- `oidc_rp_initiated_logout` depends on: `oidc`
-
-This is a **strong dependency injection pattern**.

-### Via Rodauth-Rails Wrapper
-
-Rodauth-OAuth can be used in Rails through the `rodauth-rails` gem:
-
-```bash
-# Install generator
-gem 'rodauth-rails'
-bundle install
-rails generate rodauth:install
-rails generate rodauth:oauth:install  # Generates OIDC tables/migrations
-rails generate rodauth:oauth:views    # Generates templates
-```
-
-### Generated Components

-1. **Migration**: `db/migrate/*_create_rodauth_oauth.rb`
-   - Creates all OAuth tables
-   - Customizable column names via config
-
-2. **Models**: `app/models/`
-   - `RodauthApp` (configuration)
-   - `OauthApplication` (client app)
-   - `OauthGrant` (grants/tokens)
-   - Customizable!
-
-3. **Views**: `app/views/rodauth/`
-   - Authorization consent form
-   - Application management dashboard
-   - Grant management dashboard
-
-4. **Lib**: `lib/rodauth_app.rb`

-
-### Rails Controller Integration
-
-```ruby
-class BooksController < ApplicationController
-  before_action :require_oauth_authorization, only: %i[create update]
-  before_action :require_oauth_authorization_scopes, only: %i[create update]
-
-  private
-  
-  def require_oauth_authorization(scope = "books.read")
-    rodauth.require_oauth_authorization(scope)
-  end
-end
-```
-
-Or for route protection:
-
-```ruby
-# config/routes.rb

-## Code Examples
-
-### Rodauth-OAuth: Minimal OAuth Server
-```ruby
-# Gemfile
-gem 'roda'
-gem 'rodauth-oauth'
-gem 'sequel'
-
-# lib/auth_server.rb
-class AuthServer < Roda
-  plugin :sessions, secret: ENV['SESSION_SECRET']
-  plugin :rodauth do
-    db DB
-    enable :login, :logout, :create_account, 
-           :oidc, :oauth_pkce, :oauth_authorization_code_grant,
-           :oauth_token_revocation
-    
-    oauth_application_scopes %w[openid email profile]
-    oauth_require_pkce true
-  end
-  
-  route do |r|
-    r.rodauth  # All OAuth endpoints auto-mounted!
-    
-    # Your app logic here
-  end
-end
-```
-
-That's it! All these endpoints are automatically available:
- GET /.well-known/openid-configuration
- GET /.well-known/jwks.json
- GET /oauth/authorize
- POST /oauth/token
- POST /oauth/revoke
- GET /oauth/userinfo
- GET /logout
-
-### Your Current Approach
-```ruby
-# app/controllers/oidc_controller.rb
-class OidcController < ApplicationController
-  def authorize
-    # 150 lines of validation logic
-  end
-  
-  def token
-    # 100 lines of token generation logic
-  end
-  
-  def userinfo
-    # 50 lines of claims logic
-  end
-  
-  def logout
-    # 50 lines of logout logic
-  end
-  
-  private
-  
-  def validate_pkce(auth_code, code_verifier)
-    # 50 lines of PKCE validation
-  end
-end
-```
-
-## Integration Paths
-
-### Option 1: Stick with Your Implementation
- Keep building features incrementally
- Effort: 2-3 months to reach feature parity
- Pro: Rails native, full control
- Con: Continuous maintenance burden
-
-### Option 2: Switch to Rodauth-OAuth
- Learn Roda/Rodauth (1-2 weeks)
- Migrate database (1 week)
- Replace 450 lines of code with config (1 week)
- Testing & validation (2-3 weeks)
- Effort: 4-8 weeks total
- Pro: Production-ready, certified, maintained
- Con: Different framework (Roda)
-
-### Option 3: Hybrid Approach
- Keep your Rails app for business logic
- Use rodauth-oauth as separate OAuth/OIDC service
- Services communicate via HTTP/APIs
- Effort: 2-3 weeks (independent services)
- Pro: Best of both worlds
- Con: Operational complexity
-
-## Decision Matrix
-
-### Use Rodauth-OAuth If You Need...
- [x] Standards compliance (OpenID certified)
- [x] Multiple grant types (Client Credentials, Device Code, etc.)
- [x] Token revocation/introspection
- [x] Refresh tokens
- [x] Advanced logout (front/back-channel)
- [x] Session management
- [x] Token hashing/security best practices
- [x] Hands-off maintenance
- [x] Production-battle-tested code
-
-### Keep Your Implementation If You...
- [x] Only need Authorization Code + PKCE
- [x] Want zero Roda/external framework learning
- [x] Value Rails patterns over standards
- [x] Like to understand every line of code
- [x] Can allocate time for ongoing maintenance
- [x] Prefer minimal dependencies
-
-## Key Differences You'll Notice
-
-### 1. Framework Paradigm
- **Your impl**: Rails (MVC, familiar)
- **Rodauth**: Roda (routing-focused, lightweight)
-
-### 2. Database ORM
- **Your impl**: ActiveRecord (Rails native)
- **Rodauth**: Sequel (lighter, more control)
-
-### 3. Configuration Style
- **Your impl**: Rails initializers, environment variables
- **Rodauth**: Plugin block with DSL
-
-### 4. Model Management
- **Your impl**: Rails models with validations, associations
- **Rodauth**: Minimal models, logic in database
-
-### 5. Testing Approach
- **Your impl**: RSpec, model/controller tests
- **Rodauth**: Request-based integration tests

-
-## Performance Considerations
-
-### Your Implementation
- Small tables → fast queries
- Fewer columns → less overhead
- Simple token validation
- Estimated: 5-10ms per token validation
-
-### Rodauth-OAuth
- More columns, but same queries
- Optional token hashing (slight overhead)
- More features = more options checked
- Estimated: 10-20ms per token validation
- Can be optimized: disable unused features
-
-## Getting Started (If You Want to Explore)
-
-1. **Review the code**
-   ```bash
-   cd /Users/dkam/Development/clinch/tmp/rodauth-oauth
-   ls -la lib/rodauth/features/  # See all features
-   cat examples/oidc/authentication_server.rb  # Full working example
-   ```
-
-2. **Run the example**
-   ```bash
-   cd /Users/dkam/Development/clinch/tmp/rodauth-oauth/examples
-   ruby oidc/authentication_server.rb  # Starts server on http://localhost:9292
-   ```
-
-3. **Read the key files**
-   - README.md: Overview
-   - MIGRATION-GUIDE-v1.md: Version migration (shows architecture)
-   - test/migrate/*.rb: Database schema
-   - examples/oidc/*.rb: Complete working implementation
-
-## Next Steps
-
-1. **If keeping your implementation:**
-   - Prioritize refresh token support
-   - Add token revocation endpoint
-   - Consider token hashing
-
-2. **If exploring rodauth-oauth:**
-   - Run the example server
-   - Review the feature files
-   - Check if hybrid approach works for your org
-
-3. **For either path:**
-   - Document your decision
-   - Plan feature roadmap
-   - Set up appropriate monitoring
-
---
-
-**Bottom Line**: Rodauth-OAuth is the "production-grade" option if you need comprehensive OAuth/OIDC. Your implementation is fine if you keep features minimal and have maintenance bandwidth.
