+# BZOD REST API
+
+> Programmatic access to URLs, Landing Pages, QR Codes, Analytics, and Audit Logs.
+
+## Overview
+
+The BZOD REST API allows automation and integration with external systems such as:
+
+* Home Assistant
+* Shell Scripts
+* CI/CD Pipelines
+* Monitoring Systems
+* Internal Applications

+# BZOD Architecture Guide
+
+Version: v0.5.1
+
+---
+
+# Overview
+
+BZOD is a self-hosted multi-user URL management platform written in Rust.
+
+The platform combines:
+
+* URL shortening
+* Landing pages
+* QR code generation
+* Analytics
+* User management
+* Moderation
+* Audit logging
+* Backup & restore
+* Disaster recovery
+
+into a single deployable binary powered entirely by SQLite.
+
+BZOD is designed around operational simplicity, tenant isolation, and long-term maintainability.
+
+---
+
+# Architectural Goals
+
+The primary design goals are:
+
+1. Self-hosted first
+2. SQLite-first architecture
+3. Multi-user operation
+4. Tenant isolation
+5. Simple deployment
+6. Minimal dependencies
+7. Easy backup and recovery
+8. No vendor lock-in

+
+Responsible for:
+
+* HTTP routing
+* Dashboard rendering
+* Form handling
+* Authentication checks
+* Redirect handling
+* REST API endpoints
+
+Major modules:
+
+```text
+admin.rs
+api.rs
+pages.rs
+redirect.rs
+qr.rs
+system.rs
+multi_user.rs
+routes.rs
+```
+
+---
+
+## Authentication Layer
+
+Location:
+
+```text

+```
+
+Responsible for:
+
+* Password hashing
+* Session validation
+* Cookie management
+* CSRF protection
+* Authorization
+
+Modules:
+
+```text
+csrf.rs
+middleware.rs
+password.rs
+session.rs
+```
+
+Authentication technologies:
+
+* Argon2id password hashing
+* Session cookies
+* CSRF tokens
+* RBAC checks
+
+---
+
+## Database Layer
+
+Location:
+
+```text

+```
+
+Responsible for:
+
+* Schema creation
+* Migrations
+* Database access
+* Analytics storage
+* User management
+
+Modules:
+
+```text
+admin.rs
+analytics.rs
+audit_events.rs
+content.rs
+migrations.rs
+sqlite.rs
+users.rs
+```
+
+---
+
+# Database Architecture
+
+BZOD uses multiple SQLite databases rather than a single monolithic database.
+
+This approach provides:
+
+* Better isolation
+* Easier backup
+* Simpler disaster recovery
+* Reduced risk of cross-user data leakage
+
+---
+
+## users.db
+
+Purpose:
+
+Central identity and account database.
+
+Contains:
+
+```text
+users
+sessions
+api_tokens
+quotas
+```
+
+Stores:
+
+* User accounts
+* Password hashes
+* Session records
+* API tokens
+* Quota information
+
+---
+
+## system.db
+
+Purpose:
+
+Global platform metadata.
+
+Contains:
+
+```text
+global_slugs
+audit_events
+moderation_events
+reserved_slugs
+settings
+slug_history
+```
+
+Stores:
+
+* Global slug ownership
+* Audit records
+* Moderation actions
+* Platform settings
+* Slug transfers
+
+---
+
+## Tenant Databases
+
+Each user receives isolated databases.
+
+Directory structure:
+
+```text
+users/
+└── <user_id>/
+    ├── content.db
+    └── analytics.db
+```
+
+---
+
+### content.db
+
+Stores:
+
+* URLs
+* Landing pages
+* Metadata
+
+---
+
+### analytics.db
+
+Stores:
+
+* Visits
+* Referrers
+* QR scans
+* Browser information
+* Analytics aggregates
+
+---
+
+# Multi-User Architecture
+
+BZOD v0.5.0 introduced complete tenant isolation.
+
+Each user owns:
+
+```text
+content.db
+analytics.db
+```
+
+Users cannot directly access:
+
+* Other users' URLs
+* Other users' landing pages
+* Other users' analytics
+
+The administrator accesses all tenants through controlled administrative interfaces.
+
+---
+
+# Global Slug Namespace
+
+All public URLs are tracked in:
+
+```text
+system.db -> global_slugs
+```
+
+Purpose:
+
+Prevent collisions across users.
+
+Example:
+
+```text
+User A owns:
+
+https://bzo.in/!office
+
+User B cannot create:
+
+https://bzo.in/!office
+```
+
+This guarantees global uniqueness.

+
+# Services Layer
+
+Location:
+
+```text

+```
+
+Purpose:
+
+Business logic abstraction.
+
+Modules:
+
+```text
+api_keys.rs
+audit.rs
+bulk.rs
+landing_pages.rs
+qr.rs
+shortener.rs
+```
+
+This layer separates business rules from HTTP handlers.
+
+---
+
+# CLI Architecture
+
+Location:
+
+```text
+src/cli/
+```
+
+The CLI and Web UI share the same internal services.
+
+Examples:
+
+```bash
+bzod create-admin
+bzod create-user
+bzod backup
+bzod restore
+bzod doctor
+bzod migrate
+```
+
+This avoids duplicate logic between administration methods.
+
+---
+
+# Security Model
+
+Security mechanisms:
+
+## Authentication
+
+* Argon2id password hashes
+* Session cookies
+
+## Authorization
+
+* RBAC
+* Administrative permission checks
+
+## CSRF Protection
+
+* Form tokens
+* Request validation
+
+## Tenant Isolation
+
+* Separate databases
+* Controlled access paths
+
+## Audit Logging
+
+All critical operations are recorded.
+
+Examples:
+
+* Login attempts
+* User creation
+* Password resets
+* Slug transfers
+* Moderation actions
+
+---
+
+# Backup & Recovery
+

+
+```text
+users.db
+system.db
+admin/
+users/*
+```
+

+# Disaster Recovery Scenarios
+
+## Scenario 1: Deleted User
+
+Problem:
+
+```text
+User account accidentally deleted.
+```
+
+Recovery:
+
+```bash
+bzod restore-user user-42.zip
+```
+
+Verify:
+
+* URLs restored
+* Pages restored
+* Analytics restored
+
+---
+
+## Scenario 2: Corrupted Tenant Database
+
+Problem:
+
+```text
+content.db corruption
+```
+
+Recovery:
+
+```bash
+bzod restore-user user-42.zip
+```
+
+or
+
+```bash
+bzod restore full-backup.zip
+```
+
+---
+
+## Scenario 3: Corrupted users.db
+
+Problem:
+
+```text
+Unable to login
+Missing users
+Session failures
+```
+
+Recovery:
+
+```bash
+bzod restore full-backup.zip
+```
+
+---
+
+## Scenario 4: Corrupted system.db
+
+Problem:
+
+```text
+Slug resolution failures
+Moderation data missing
+Settings lost
+```
+
+Recovery:
+
+```bash
+bzod restore full-backup.zip
+```
+
+---
+
+## Scenario 5: Complete Server Failure
+
+Problem:
+
+```text
+Disk failure
+Server loss
+Hardware replacement
+```
+
+Recovery:
+
+1. Reinstall operating system
+2. Install BZOD
+3. Restore backup
+
+```bash
+bzod restore backup.zip
+```
+
+4. Start BZOD
+
+```bash
+bzod serve
+```
+
+---
+
+# WAL Mode
+
+BZOD uses SQLite Write-Ahead Logging (WAL).
+
+Examples:
+
+```text
+users.db
+users.db-wal
+users.db-shm
+
+system.db
+system.db-wal
+system.db-shm
+
+content.db
+content.db-wal
+content.db-shm
+
+analytics.db
+analytics.db-wal
+analytics.db-shm
+```
+
+Benefits:
+
+* Improved concurrency
+* Better crash recovery
+* Faster write operations
+
+---
+
+# Backup Safety
+
+Do not manually copy live SQLite databases while the server is actively writing.
+
+Always use:
+
+```bash
+bzod backup
+```
+
+or the Backup Management UI.
+
+This ensures consistent snapshots.
+
+---
+
+# Security Considerations
+
+Backups may contain:
+
+* User accounts
+* Password hashes
+* Session metadata
+* Analytics data
+* Audit records
+* API token hashes
+
+Even though passwords and tokens are stored as hashes, backup archives should be treated as sensitive information.
+
+Recommended practices:
+
+* Encrypt backup storage
+* Restrict filesystem permissions
+* Maintain offsite copies
+* Transfer backups over secure channels
+* Test restores periodically
+
+---
+
+# Backup Testing
+
+A backup is only useful if it can be restored.
+
+Quarterly validation is recommended.
+
+Example:
+
+```bash
+mkdir restore-test
+
+bzod restore backup.zip \
+    --data-dir restore-test
+```
+
+Verify:
+
+* Login works
+* URLs resolve
+* Landing pages load
+* Analytics display
+* Administration dashboard functions
+
+---
+
+# Production Recommendation
+
+Minimum production policy:
+
+```text
+Daily Full Backup
+Weekly Offsite Backup
+Monthly Archive Backup
+Quarterly Restore Validation
+```
+
+Following this policy protects against:
+
+* User mistakes
+* Database corruption
+* Upgrade failures
+* Hardware failures
+* Site disasters
+
+and provides a reliable recovery path for BZOD deployments.

+
+# BZOD Database Architecture
+
+BZOD v0.5.1 uses SQLite exclusively.
+
+Rather than using a single monolithic database, BZOD separates data into administrative and tenant-specific databases. This architecture improves security, isolation, backup flexibility, disaster recovery, and scalability.
+
+---
+
+# Overview
+
+BZOD stores data in the following structure:
+
+```text
+data/
+├── admin/
+│   ├── admin.db
+│   ├── system.db
+│   └── users.db
+│
+└── users/
+    ├── 1/
+    │   ├── analytics.db
+    │   ├── content.db
+    │   └── profile.db
+    │
+    ├── 2/
+    │   ├── analytics.db
+    │   ├── content.db
+    │   └── profile.db
+    │
+    └── N/
+        ├── analytics.db
+        ├── content.db
+        └── profile.db
+```
+
+Each user receives isolated databases.
+
+No user content or analytics are stored in the central administrative databases.
+
+---
+
+# Administrative Databases
+
+Administrative databases are located under:
+
+```text
+data/admin/
+```
+
+---
+
+# users.db
+
+Primary authentication and user management database.
+
+Purpose:
+
+* User accounts
+* Password hashes
+* Sessions
+* Quotas
+* API tokens
+* User status tracking
+
+Typical tables:
+
+```text
+users
+sessions
+quotas
+api_tokens
+```
+
+Responsibilities:
+
+* Authentication
+* Authorization
+* Session management
+* Account status
+* Quota enforcement
+
+This is the primary identity database of the platform.
+
+---
+
+# system.db
+
+Global platform database.
+
+Purpose:
+
+* Global slug namespace
+* Moderation
+* Auditing
+* System configuration
+
+Typical tables:
+
+```text
+global_slugs
+slug_history
+moderation_events
+audit_events
+reserved_slugs
+settings
+```
+
+Responsibilities:
+
+* Global slug uniqueness
+* Slug ownership
+* Moderation actions
+* Audit logging
+* System settings
+
+Every redirect ultimately resolves through records stored in this database.
+
+---
+
+# admin.db
+
+Administrative application database.
+
+Purpose:
+
+* Administrative metadata
+* Administrative API key records
+* Legacy compatibility structures
+* Internal management data
+
+Typical tables:
+
+```text
+api_keys
+audit_events
+```
+
+This database is reserved for administrative functions and does not store tenant content.
+
+---
+
+# Tenant Databases
+
+Tenant databases are located under:
+
+```text
+data/users/{user_id}/
+```
+
+Each user owns a completely isolated set of databases.
+
+Example:
+
+```text
+data/users/2/
+├── analytics.db
+├── content.db
+└── profile.db
+```
+
+---
+
+# content.db
+
+Stores user-owned content.
+
+Purpose:
+
+* Short URLs
+* Landing pages
+* QR metadata
+* Preview metadata
+
+Typical tables:
+
+```text
+urls
+pages
+qr_codes
+previews
+```
+
+Responsibilities:
+
+* URL management
+* Landing page management
+* Content ownership
+
+This database contains the actual resources owned by a user.
+
+---
+
+# analytics.db
+
+Stores traffic and visitor information.
+
+Purpose:
+
+* Visit recording
+* Referrer tracking
+* Browser tracking
+* Country statistics
+* Aggregated analytics
+
+Typical tables:
+
+```text
+visits
+referrers
+browsers
+countries
+daily_stats
+```
+
+Responsibilities:
+
+* Analytics collection
+* Reporting
+* Dashboard statistics
+
+Analytics are fully isolated per user.
+
+Administrators access aggregated analytics by querying each user's analytics database.
+
+---
+
+# profile.db
+
+Stores user-specific profile information.
+
+Purpose:
+
+* User preferences
+* Profile settings
+* Future extensible metadata
+
+Typical tables:
+
+```text
+profile
+preferences
+```
+
+Responsibilities:
+
+* User profile management
+* Dashboard preferences
+* Future personalization features
+
+---
+
+# Database Isolation Model
+
+BZOD follows a strict tenant isolation model.
+
+```text
+User A
+ ├── content.db
+ ├── analytics.db
+ └── profile.db
+
+User B
+ ├── content.db
+ ├── analytics.db
+ └── profile.db
+```
+
+User databases never share tables.
+
+Cross-user content access is prevented by design.
+
+Benefits:
+
+* Security
+* Easier backups
+* Easier deletion
+* Reduced corruption impact
+
+---
+
+# Global Slug Registry
+
+The system maintains a single namespace.
+
+Stored in:
+
+```text
+system.db
+```
+
+Table:
+
+```text
+global_slugs
+```
+
+Example:
+
+```text
+abc123 → User 2 URL
+docs → User 5 Page
+demo → User 1 URL
+```
+
+This guarantees:
+
+* Global uniqueness
+* Ownership tracking
+* Moderation support
+* Slug transfer support
+
+---
+
+# Write Flow
+
+Creating a URL:
+
+```text
+1. Validate quota
+2. Register slug in system.db
+3. Create URL in content.db
+4. Update quota counters
+5. Write audit event
+```
+
+Creating a landing page:
+
+```text
+1. Validate quota
+2. Register slug in system.db
+3. Create page in content.db
+4. Update quota counters
+5. Write audit event
+```
+
+---
+
+# Analytics Flow
+
+Visitor request:
+
+```text
+GET /abc123
+```
+
+Process:
+
+```text
+global_slugs
+        ↓
+content.db lookup
+        ↓
+redirect
+        ↓
+analytics.db visit record
+```
+
+Analytics writes never modify content records.
+
+---
+
+# WAL Mode
+
+All databases operate in SQLite WAL mode.
+
+Verify:
+
+```sql
+PRAGMA journal_mode;
+```
+
+Expected:
+
+```text
+wal
+```
+
+Benefits:
+
+* Improved concurrency
+* Reduced write contention
+* Crash recovery
+
+Associated files:
+
+```text
+*.db
+*.db-shm
+*.db-wal
+```
+
+---
+
+# WAL Checkpointing
+
+Large WAL files are normal during heavy traffic.
+
+Example:
+
+```text
+analytics.db-wal
+content.db-wal
+```
+
+To manually checkpoint:
+
+```sql
+PRAGMA wal_checkpoint(TRUNCATE);
+```
+
+The healthcheck and backup jobs may trigger checkpoints automatically.
+
+---
+
+# Backups
+
+Recommended:
+
+```bash
+bzod backup
+```
+
+This creates a consistent archive of:
+
+```text
+admin/
+users/
+```
+
+Never manually copy live databases while the application is running.
+
+---
+
+# Integrity Verification
+
+Run:
+
+```bash
+bzod doctor
+```
+
+Or:
+
+```sql
+PRAGMA integrity_check;
+```
+
+Expected:
+
+```text
+ok
+```
+
+---
+
+# Migration System
+
+BZOD maintains schema versions using:
+
+```sql
+PRAGMA user_version;
+```
+
+Startup automatically executes:
+
+```text
+Db::init()
+```
+
+which:
+
+1. Creates missing databases
+2. Applies migrations
+3. Validates schemas
+4. Repairs legacy installations when required
+
+---
+
+# Design Principles
+
+BZOD database architecture prioritizes:
+
+* SQLite-only deployment
+* Multi-user isolation
+* Operational simplicity
+* Backup friendliness
+* Easy disaster recovery
+* Minimal dependencies
+* Single-binary deployment

+# BZOD Multi-User Architecture Guide
+
+Version: v0.5.1
+
+---
+
+# Introduction
+
+BZOD v0.5.0 introduces a complete multi-user architecture that transforms BZOD from a single-tenant URL shortener into a secure, isolated, self-hosted multi-user platform.
+
+Each user receives logically isolated content and analytics storage while sharing a common authentication, administration, moderation, and routing infrastructure.
+
+This document explains the architecture, database layout, ownership model, security boundaries, quotas, slug management, and administrative workflows.
+
+---
+
+# Design Goals
+
+The multi-user architecture was designed around the following principles:
+
+* Strong tenant isolation
+* Single binary deployment
+* SQLite-only operation
+* Minimal operational complexity
+* No external services required
+* Global slug namespace
+* Centralized administration
+* Disaster recovery support
+* Simple backup and restore workflows
+
+---
+
+# User Types
+
+BZOD supports the following account types.
+
+## Administrator
+
+Administrators can:
+
+* Access the administrative dashboard
+* Create users
+* Delete users
+* Reset passwords
+* Manage quotas
+* Transfer ownership
+* Moderate content
+* Manage backups
+* Access health dashboards
+* Access audit logs
+
+Administrators cannot bypass database isolation.
+
+---
+
+## Standard User
+
+Standard users can:
+
+* Create short URLs
+* Create landing pages
+* View analytics
+* Generate QR codes
+* Manage API tokens
+* Update passwords
+
+Standard users cannot:
+
+* Access other user content
+* Access administrative functions
+* Access system settings
+
+---
+
+## System Accounts
+
+System accounts are reserved for internal operations.
+
+They cannot authenticate into the dashboard.
+
+---
+
+# Database Architecture
+
+BZOD uses multiple SQLite databases.
+
+## users.db
+
+Central identity store.
+
+Contains:
+
+```text
+users
+sessions
+quotas
+api_tokens
+```
+
+Responsibilities:
+
+* Authentication
+* Session management
+* Password verification
+* User status management
+* Quota tracking
+
+---
+
+## system.db
+
+Global platform database.
+
+Contains:
+
+```text
+global_slugs
+slug_history
+moderation_events
+audit_events
+settings
+reserved_slugs
+```
+
+Responsibilities:
+
+* Slug ownership
+* Moderation
+* Audit logging
+* Global settings
+* System metadata
+
+---
+
+## Tenant Databases
+
+Every tenant owns independent databases.
+
+Example:
+
+```text
+users/
+└── 15/
+    ├── content.db
+    └── analytics.db
+```
+
+Responsibilities:
+
+### content.db
+
+Stores:
+
+```text
+urls
+pages
+qr_metadata
+previews
+```
+
+### analytics.db
+
+Stores:
+
+```text
+visits
+aggregates
+referrers
+browsers
+countries
+```
+
+---
+
+# Directory Structure
+
+Example installation:
+
+```text
+data/
+├── users.db
+├── system.db
+│
+├── admin/
+│   ├── content.db
+│   └── analytics.db
+│
+└── users/
+    ├── 2/
+    │   ├── content.db
+    │   └── analytics.db
+    │
+    ├── 3/
+    │   ├── content.db
+    │   └── analytics.db
+    │
+    └── 4/
+        ├── content.db
+        └── analytics.db
+```
+
+---
+
+# Global Slug Namespace
+
+BZOD uses a platform-wide namespace.
+
+A slug can only exist once.
+
+Examples:
+
+```text
+/company
+/about
+/docs
+```
+
+If User A owns:
+
+```text
+/company
+```
+
+User B cannot create:
+
+```text
+/company
+```
+
+The operation is rejected.
+
+---
+
+# Slug Registration Flow
+
+When a URL or page is created:
+
+1. Validate quota.
+2. Validate slug.
+3. Register slug in system.db.
+4. Create record in tenant content.db.
+5. Increment quota counters.
+6. Write audit log.
+
+If any step fails:
+
+* Changes are rolled back.
+* Partial records are removed.
+
+---
+
+# Global Slug Table
+
+Conceptually:
+
+```text
+global_slugs
+```
+
+Contains:
+
+```text
+slug
+owner_user_id
+target_type
+target_id
+status
+created_at
+```
+
+Example:
+
+| slug | owner | type |
+| ---- | ----- | ---- |
+| docs | 3     | page |
+| api  | 8     | page |
+| home | 2     | url  |
+
+---
+
+# Slug Ownership Transfer
+
+Administrators may transfer ownership.
+
+Process:
+
+1. Validate destination quotas.
+2. Copy content.
+3. Move ownership.
+4. Update global slug registry.
+5. Record history.
+6. Write audit event.
+
+Analytics remain preserved.
+
+URLs remain functional.
+
+---
+
+# Tenant Isolation
+
+Each user owns independent databases.
+
+Example:
+
+```text
+User A
+└── users/2/
+
+User B
+└── users/3/
+```
+
+User A never accesses:
+
+```text
+users/3/content.db
+users/3/analytics.db
+```
+
+User B never accesses:
+
+```text
+users/2/content.db
+users/2/analytics.db
+```
+
+All access is enforced by application logic.
+
+---
+
+# Authentication Architecture
+
+Authentication is centralized.
+
+Stored in:
+
+```text
+users.db
+```
+
+Tables:
+
+```text
+users
+sessions
+```
+
+All dashboard sessions use:
+
+```text
+bzod_session
+```
+
+Sessions are validated against:
+
+```text
+users.db.sessions
+```
+
+---
+
+# Session Lifecycle
+
+Login:
+
+```text
+User Login
+    ↓
+Create Session
+    ↓
+Store in users.db
+    ↓
+Set bzod_session cookie
+```
+
+Logout:
+
+```text
+Delete session row
+    ↓
+Expire cookie
+```
+
+Disabled users immediately lose access.
+
+---
+
+# Quota System
+
+Every user has quotas.
+
+Examples:
+
+```text
+max_urls
+max_pages
+max_storage_mb
+max_api_tokens
+```
+
+Current utilization is tracked separately.
+
+Administrators may:
+
+* Increase limits
+* Reduce limits
+* Trigger reconciliation
+
+---
+
+# Quota Reconciliation
+
+Background job:
+
+```text
+quota_reconcile
+```
+
+Purpose:
+
+* Detect drift
+* Recount resources
+* Repair counters
+
+Example:
+
+```text
+Stored URLs = 50
+Actual URLs = 47
+```
+
+Counter automatically corrected.
+
+---
+
+# Analytics Isolation
+
+Each tenant stores analytics independently.
+
+Example:
+
+```text
+users/10/analytics.db
+```
+
+Contains only User 10 traffic.
+
+Administrators can:
+
+* View aggregated analytics
+* Access user analytics
+
+Users cannot view analytics from other tenants.
+
+---
+
+# QR Code System
+
+QR codes are generated dynamically.
+
+Endpoints:
+
+```text
+/api/qr/{slug}.png
+/api/qr/{slug}.svg
+```
+
+Slug ownership is resolved through:
+
+```text
+system.db.global_slugs
+```
+
+No content database scan is required.
+
+---
+
+# Moderation Architecture
+
+Administrators can:
+
+* Flag content
+* Disable content
+* Delete content
+* Transfer ownership
+
+Disabled content returns:
+
+```http
+410 Gone
+```
+
+For:
+
+```text
+/slug
+/p/slug
+/api/qr/slug.png
+/api/qr/slug.svg
+```
+
+---
+
+# Audit Logging
+
+All administrative actions are recorded.
+
+Examples:
+
+```text
+login
+logout
+user_create
+user_delete
+password_reset
+quota_update
+slug_transfer
+backup_create
+restore_execute
+```
+
+Stored in:
+
+```text
+system.db
+```
+
+---
+
+# Backup Architecture
+
+Supported levels:
+
+## Full Platform Backup
+
+Includes:
+
+```text
+users.db
+system.db
+all tenant databases
+```
+
+---
+
+## User Backup
+
+Includes:
+
+```text
+content.db
+analytics.db
+```
+
+For a specific user.
+
+---
+
+# Disaster Recovery
+
+Supported operations:
+
+```bash
+bzod backup
+bzod restore
+bzod backup-user
+bzod restore-user
+```
+
+Recovery preserves:
+
+* URLs
+* Pages
+* Analytics
+* Users
+* Slugs
+* Settings
+
+---
+
+# Upgrade Path
+
+BZOD automatically migrates:
+
+```text
+v0.4.x
+```
+
+to
+
+```text
+v0.5.x
+```
+
+Migration process:
+
+1. Create users.db.
+2. Create system.db.
+3. Create admin tenant.
+4. Migrate content.
+5. Migrate analytics.
+6. Populate global_slugs.
+7. Create legacy_admin.
+8. Validate integrity.
+
+No manual database migration is normally required.
+
+---
+
+# Security Model
+
+Security boundaries:
+
+## Authentication
+
+Centralized.
+
+```text
+users.db
+```
+
+---
+
+## Authorization
+
+Role-based.

+# BZOD v0.5.1 — Namespace Integrity & Platform Hardening
+
+**Release Date:** 2026-06-20
+
+BZOD v0.5.1 focuses on platform integrity, multi-tenant safety, dashboard parity, QR reliability, and upgrade validation.
+
+While v0.5.0 introduced the multi-user architecture, v0.5.1 strengthens the foundations required for safe operation at scale.
+
+---
+
+# Highlights
+## Runtime Efficiency (v0.5.1)
+
+| Metric              | Value      |
+|---------------------|------------|
+| Binary Size         | 11 MB      |
+| RSS Memory          | 11.8 MB    |
+| Peak RSS            | 11.8 MB    |
+| CPU Idle            | 0.02%      |
+| Swap Usage          | 0 KB       |
+| PIDs                | 7          |
+
+**On a typical 32 GB server:**
+- Memory usage: ~0.04%
+- No swapping
+- Plenty of headroom
+
+BZOD runs closer to a lightweight infrastructure service than a typical web application.
+
+## Global Slug Registry
+
+Introduced a hardened global slug registry to guarantee namespace integrity across the entire platform.
+
+The following resources can no longer share the same slug:
+
+* Administrator URLs
+* Administrator Landing Pages
+* User URLs
+* User Landing Pages
+
+Duplicate namespace conflicts are automatically detected and blocked.
+
+---
+
+## Namespace Integrity Validation
+
+New validation routines now verify:
+
+* Duplicate slug detection
+* Missing ownership records
+* Invalid registry entries
+* Invalid target types
+* Orphaned slug references
+
+Namespace conflicts now abort upgrades and restores before corruption can occur.
+
+---
+
+## Reservation-Based Slug Allocation
+
+BZOD now reserves slugs before content creation.
+
+Creation workflow:
+
+```text
+Quota Check
+↓
+Reserve Global Slug
+↓
+Create Content
+↓
+Activate Slug
+↓
+Increment Quota
+↓
+Audit Log
+```
+
+Benefits:
+
+* Prevents race conditions
+* Prevents duplicate creation under concurrency
+* Enables safer rollback handling
+
+---
+
+## Stale Reservation Recovery
+
+Added automatic cleanup of abandoned slug reservations.
+
+Scenarios covered:
+
+* Server crash during creation
+* Interrupted writes
+* Failed transactions
+
+BZOD now automatically recovers stale reservations during startup.
+
+---
+
+## Dashboard Parity
+
+Administrator and Standard User dashboards now provide equivalent functionality where appropriate.
+
+Added parity validation for:
+
+* URL management
+* Landing page management
+* Analytics
+* QR code previews
+* Export functionality
+
+Differences remain only for administrator-specific operations.
+
+---
+
+## Unified Analytics Templates
+
+Removed duplicated analytics templates.
+
+Benefits:
+
+* Consistent rendering
+* Reduced maintenance burden
+* Improved reliability
+
+Administrator and user analytics now share the same rendering logic.
+
+---
+
+## QR Code Improvements
+
+QR functionality was substantially improved.
+
+### Added
+
+* Inline QR previews
+* PNG downloads
+* SVG downloads
+* Shared QR rendering component
+
+### Fixed
+
+* Landing page QR generation
+* Multi-user QR ownership handling
+* QR routing consistency
+* Content-type validation
+
+---
+
+## Canonical Landing Page Routing
+
+Landing page slugs now redirect permanently to canonical page URLs.
+
+Example:
+
+```text
+/landing-page
+```
+
+redirects to:
+
+```text
+/p/landing-page
+```
+
+using:
+
+```http
+301 Moved Permanently
+```
+
+This improves consistency and SEO behavior.
+
+---
+
+## Ownership Isolation Hardening
+
+Additional protections ensure:
+
+* Users cannot access another user's analytics
+* Users cannot export another user's data
+* Users cannot manage another user's resources
+
+New ownership validation tests were added.
+
+---
+
+## Backup & Restore Improvements
+
+Restore operations now validate namespace integrity before importing data.
+
+Benefits:
+
+* No silent slug collisions
+* No partial restores
+* No hidden ownership conflicts
+
+Restore operations fail safely when conflicts are detected.
+
+---
+
+## Upgrade Validation Enhancements
+
+Upgrade workflows now verify:
+
+* Global namespace consistency
+* Duplicate slug conflicts
+* Registry integrity
+* Tenant ownership correctness
+
+Unsafe upgrades are blocked automatically.
+
+---
+
+## Health & Diagnostics
+
+The system health subsystem now validates:
+
+* Global slug registry integrity
+* Namespace conflicts
+* Ownership consistency
+* Stale reservations
+
+This improves operational visibility and troubleshooting.
+
+---
+
+# Testing & Validation
+
+BZOD v0.5.1 passed:
+
+* Formatting validation (`cargo fmt --check`)
+* Static analysis (`cargo clippy --all-targets -- -D warnings`)
+* Full automated test suite
+* Namespace integrity tests
+* Ownership isolation tests
+* QR endpoint tests
+* Dashboard parity tests
+* Upgrade validation tests
+* Backup & restore tests
+* Disaster recovery tests
+* Security tests
+* Concurrency tests
+
+All automated tests pass successfully.
+
+---
+
+# Upgrade Notes
+
+Administrators upgrading from v0.5.0 should review:
+
+* UPGRADE.md
+* MULTI_USER.md
+* BACKUP_RESTORE.md
+* DATABASES.md
+* TESTING.md
+
+BZOD will automatically validate namespace integrity before completing upgrades.
+
+Duplicate slugs that previously existed across users or resource types must be resolved before migration can proceed.
+
+---
+
+# Breaking Changes
+
+## Global Namespace Enforcement
+
+Slugs are now globally unique across the entire platform.
+
+Configurations that previously relied on duplicate slugs across users or resource types will be rejected during upgrade.
+
+This behavior is intentional and protects routing integrity.
+
+---
+
+# Summary
+
+BZOD v0.5.1 is an integrity-focused release that significantly strengthens:
+
+* Namespace safety
+* Multi-tenant isolation
+* Dashboard consistency
+* QR reliability
+* Restore safety
+* Upgrade safety
+* Operational diagnostics
+
+The result is a more predictable, recoverable, and production-ready platform.

+
+# Security Overview
+
+BZOD is designed as a self-hosted URL shortener and landing page platform with a strong emphasis on:
+
+* Multi-user isolation
+* Secure authentication
+* Role-based access control
+* Auditability
+* Data ownership
+* Disaster recovery
+* Operational simplicity
+
+This document describes the security architecture, threat model, authentication mechanisms, authorization controls, and operational security recommendations for BZOD v0.5.0.
+
+---
+
+# Security Principles
+
+BZOD follows several core principles:
+
+1. Least Privilege
+2. Tenant Isolation
+3. Defense in Depth
+4. Auditability
+5. Secure Defaults
+6. Explicit Ownership
+7. Fail Secure
+
+---
+
+# Threat Model
+
+BZOD is designed to protect against:
+
+* Unauthorized dashboard access
+* Credential theft
+* Session hijacking
+* Cross-user data access
+* Slug takeover attempts
+* Privilege escalation
+* CSRF attacks
+* XSS injection attempts
+* Unauthorized API access
+* Malicious content modification
+* Accidental administrative mistakes
+
+BZOD is not intended to defend against:
+
+* Physical server compromise
+* Root-level operating system compromise
+* Malware running as the BZOD service user
+* Full database theft by a privileged host administrator
+
+---
+
+# Authentication
+
+Authentication is centralized in:
+
+```text
+users.db
+```
+
+Tables:
+
+```text
+users
+sessions
+api_tokens
+```
+
+All users authenticate through the same identity system.
+
+---
+
+# Password Security
+
+Passwords are never stored in plaintext.
+
+Stored values:
+
+```text
+password_hash
+```
+
+Passwords are hashed before storage.
+
+Administrative password resets generate entirely new hashes.
+
+Existing passwords cannot be recovered.
+
+---
+
+# Session Security
+
+All dashboard authentication uses:
+
+```text
+bzod_session
+```
+
+cookie.
+
+Sessions are stored in:
+
+```text
+users.db.sessions
+```
+
+Each session contains:
+
+```text
+session_id
+user_id
+created_at
+expires_at
+```
+
+---
+
+## Session Validation
+
+Each authenticated request verifies:
+
+1. Session exists
+2. Session has not expired
+3. User exists
+4. User status is active
+5. User has required permissions
+
+Failure at any step immediately invalidates access.
+
+---
+
+## Session Revocation
+
+Sessions are revoked when:
+
+* User logs out
+* User is disabled
+* User is deleted
+* Password is reset
+* Administrator revokes sessions
+
+---
+
+## Session Fixation Protection
+
+BZOD generates new session identifiers after successful authentication.
+
+Previously issued identifiers are not reused.
+
+---
+
+# Authorization Model
+
+BZOD implements Role-Based Access Control (RBAC).
+
+Supported roles:
+
+```text
+admin
+standard
+system
+```
+
+---
+
+## Administrator
+
+Administrators can:
+
+* Manage users
+* Reset passwords
+* Transfer ownership
+* Manage quotas
+* Access audit logs
+* Review analytics
+* Create backups
+* Restore backups
+* Moderate content
+
+Administrators cannot bypass audit logging.
+
+---
+
+## Standard User
+
+Standard users can:
+
+* Manage owned URLs
+* Manage owned landing pages
+* View owned analytics
+* Generate API tokens
+* Manage owned content
+
+Standard users cannot:
+
+* Access other users' content
+* Access administrative endpoints
+* Access system settings
+
+---
+
+## System Accounts
+
+System accounts are internal accounts.
+
+They cannot authenticate into:
+
+* Dashboard
+* REST API
+
+---
+
+# Multi-User Isolation
+
+Multi-user isolation is one of the primary security features of BZOD.
+
+Each tenant receives independent databases.
+
+Example:
+
+```text
+users/
+├── 2/
+│   ├── content.db
+│   └── analytics.db
+│
+├── 3/
+│   ├── content.db
+│   └── analytics.db
+```
+
+User 2 never accesses:
+
+```text
+users/3/content.db
+users/3/analytics.db
+```
+
+User 3 never accesses:
+
+```text
+users/2/content.db
+users/2/analytics.db
+```
+
+---
+
+# Global Slug Security
+
+All public slugs are stored in:
+
+```text
+system.db.global_slugs
+```
+
+Each slug is globally unique.
+
+Example:
+
+```text
+/company
+```
+
+may belong to only one owner.
+
+Duplicate registrations are rejected.
+
+---
+
+## Slug Ownership
+
+Every slug contains:
+
+```text
+owner_user_id
+target_id
+target_type
+status
+```
+
+Ownership must match before modification is permitted.
+
+---
+
+## Slug Transfer Protection
+
+Only administrators may transfer ownership.
+
+Transfer operations:
+
+1. Validate destination quotas
+2. Validate destination user
+3. Copy content
+4. Update ownership
+5. Record history
+6. Write audit event
+
+---
+
+# API Security
+
+REST API authentication uses API tokens.
+
+Tokens are stored as hashes.
+
+Plaintext tokens are shown only once during creation.
+
+---
+
+## API Token Security
+
+Stored values:
+
+```text
+token_hash
+```
+
+Never:
+
+```text
+plaintext_token
+```
+
+If a token is lost:
+
+1. Revoke it
+2. Generate a new token
+
+---
+
+## API Permissions
+
+Admin tokens:
+
+```text
+Full administrative access
+```
+
+Standard user tokens:
+
+```text
+Owned resources only
+```
+
+System accounts:
+
+```text
+API access denied
+```
+
+---
+
+# CSRF Protection
+
+All dashboard forms require valid CSRF tokens.
+
+Protected actions include:
+
+* Login
+* User creation
+* Password reset
+* Content modification
+* Moderation actions
+* Quota updates
+* Backup operations
+
+---
+
+## Invalid CSRF Requests
+
+Invalid requests return:
+
+```http
+403 Forbidden
+```
+
+and are rejected before processing.
+
+---
+
+# XSS Protection
+
+User-supplied content is validated before rendering.
+
+Templates use:
+
+```text
+Askama
+```
+
+which escapes output by default.
+
+Recommended:
+
+* Do not allow arbitrary JavaScript
+* Validate HTML content
+* Restrict trusted editors
+
+---
+
+# Content Moderation
+
+Administrators may:
+
+* Flag content
+* Disable content
+* Delete content
+
+Disabled content returns:
+
+```http
+410 Gone
+```
+
+for:
+
+```text
+/{slug}
+/p/{slug}
+/api/qr/{slug}.png
+/api/qr/{slug}.svg
+```
+
+---
+
+# Audit Logging
+
+Security-sensitive actions are logged.
+
+Examples:
+
+```text
+login
+logout
+failed_login
+user_created
+user_deleted
+password_reset
+slug_transfer
+quota_update
+backup_created
+restore_executed
+```
+
+Stored in:
+
+```text
+system.db
+```
+
+Audit logs should be reviewed regularly.
+
+---
+
+# Backup Security
+
+Backups may contain:
+
+* User records
+* Session records
+* URLs
+* Pages
+* Analytics
+* API token hashes
+
+Backups should be treated as sensitive data.
+
+---
+
+## Recommendations
+
+Store backups:
+
+* Offsite
+* Encrypted
+* Access-controlled
+
+Never expose backup archives publicly.
+
+---
+
+# Database Security
+
+SQLite databases should be accessible only to the BZOD service account.
+
+Recommended permissions:
+
+```bash
+chmod 700 data
+chmod 600 *.db
+```
+
+---
+
+# HTTPS Requirements
+
+Production deployments should always use HTTPS.
+
+Recommended reverse proxies:
+
+* Nginx
+* Caddy
+* Traefik
+
+Never expose login pages over plaintext HTTP.
+
+---
+
+# Security Headers
+
+Recommended reverse proxy headers:
+
+```http
+X-Frame-Options: DENY
+X-Content-Type-Options: nosniff
+Referrer-Policy: strict-origin-when-cross-origin
+Content-Security-Policy: default-src 'self'
+```
+
+---
+
+# Password Policy Recommendations
+
+Recommended minimum:
+
+```text
+12 characters
+```
+
+Encourage:
+
+* Password managers
+* Unique passwords
+* Randomly generated credentials
+
+Avoid:
+
+* Reused passwords
+* Dictionary words
+* Predictable patterns
+
+---
+
+# Brute Force Protection
+
+Recommended deployment protections:
+
+* Reverse proxy rate limiting
+* Fail2Ban
+* Firewall rules
+
+Example:
+
+```text
+5 login attempts
+within 5 minutes
+```
+
+before temporary blocking.
+
+---
+
+# Administrative Security Checklist
+
+Before production deployment:
+
+* Enable HTTPS
+* Configure backups
+* Review file permissions
+* Remove default credentials
+* Verify audit logging
+* Test restore procedures
+* Review active sessions
+
+---
+
+# Incident Response
+
+If compromise is suspected:
+
+1. Disable affected accounts.
+2. Revoke active sessions.
+3. Revoke API tokens.
+4. Create forensic backup.
+5. Review audit logs.
+6. Restore from trusted backups if necessary.
+7. Rotate credentials.
+
+---

+* Authorization
+* Session validation
+* CSRF enforcement
+* Slug ownership
+* User isolation
+* Upgrade migrations
+* Backup integrity
+* Disaster recovery
+
+These tests are executed during CI and release validation.
+
+---
+

-# BZOD Test Procedures
+## Overview

-This document describes the official verification procedures for BZOD.
+BZOD follows a defense-in-depth validation strategy.

-The objective is not merely to confirm that code compiles, but to ensure that the complete platform can be built, deployed, backed up, restored, migrated, and recovered successfully.
+A release is considered valid only when:
+
+* Code quality checks pass
+* Automated tests pass
+* Upgrade validation passes
+* Backup/restore validation passes
+* Namespace integrity validation passes
+* Multi-user isolation validation passes
+* Disaster recovery validation passes
+
+The objective is not simply to ensure the application starts, but to ensure that it can be safely upgraded, operated, backed up, restored, and recovered.

 ---

-# Philosophy
+# Validation Philosophy

 BZOD prioritizes:

-1. Data Integrity
-2. Operational Simplicity
-3. Recovery Capability
-4. Deployment Reproducibility
-5. Functional Correctness
+1. Namespace Integrity
+2. Data Integrity
+3. Multi-Tenant Isolation
+4. Operational Simplicity
+5. Recovery Capability
+6. Security
+7. Functional Correctness

-A passing unit test suite alone is insufficient.
+A successful release is not merely one that runs.

-A release is considered valid only if backup, restore, migration, and recovery procedures have been verified.
+A successful release is one that can be recovered.

-## 15. Upgrade Verification
+# Release Validation Checklist

-1. Create backup.
-2. Upgrade binary.
-3. Run migration.
-4. Start service.
+Before every release:

 ```bash
-./bzod backup
+cargo fmt --check

-./bzod migrate
+cargo clippy --all-targets -- -D warnings

-./bzod serve
+cargo test --all-targets -- --nocapture
+
+cargo build --release
+
+cargo audit
 ```

-Expected Result:
-
-* Existing data preserved
-* No migration failures
+Release is approved only if all steps succeed.

 ---

-# Release Acceptance Criteria
+# Release Blockers

-A release is considered production-ready only if:
+The following are release blockers:

-* Build verification passes
-* Static analysis passes
-* Unit tests pass
-* Backup verification passes
-* Restore verification passes
-* Disaster recovery verification passes
-* Doctor reports HEALTHY
-* Docker deployment succeeds
-* Web UI functions correctly
+* Namespace conflicts
+* Backup failure
+* Restore failure
+* Upgrade failure
+* Multi-user isolation failure
+* Ownership validation failure
+* Security test failure
+* Data corruption
+* Disaster recovery failure

-Failure of backup, restore, or disaster recovery tests is considered a release blocker.
-
---
-
-# Guiding Principle
-
-A successful release is not merely one that starts.
-
-A successful release is one that can be recovered.
+A release that cannot be restored is not considered production ready.

+v0.4.x → v0.5.1
+```
+
+Recommended:
+
+```text
+v0.4.x → v0.5.0 → v0.5.1
+```
+
+Unsupported:
+
+```text
+v0.3.x → v0.5.1
+```
+
+Older installations should first upgrade to v0.4.x.
+
+---
+
+# Major Changes in v0.5.1
+
+## Global Namespace Enforcement
+
+BZOD now enforces a single platform-wide slug namespace.
+
+The following resources can no longer share the same slug:
+
+* Administrator URLs
+* Administrator Landing Pages
+* User URLs
+* User Landing Pages
+
+Example:
+
+```text
+Admin URL:
+hello
+
+User URL:
+hello
+```
+
+Result:
+
+```text
+Upgrade aborted.
+Namespace conflict detected.
+```
+
+---
+
+## Global Slug Registry
+
+BZOD now treats the slug registry as the authoritative source of truth.
+
+All slugs are registered in:
+
+```text
+system.db
+```
+
+Table:
+
+```text
+global_slugs
+```
+
+The registry tracks:
+
+```text
+slug
+owner_user_id
+target_type
+target_id
+status
+```
+
+---
+
+## Reservation-Based Slug Allocation
+
+Slug creation now follows:
+
+```text
+Quota Validation
+↓
+Reserve Global Slug
+↓
+Create Resource
+↓
+Activate Slug
+↓
+Update Quotas
+↓
+Audit Log
+```
+
+Benefits:
+
+* Prevents race conditions
+* Prevents duplicate allocations
+* Improves rollback safety
+* Improves multi-user integrity
+
+---
+
+## Stale Reservation Recovery
+
+BZOD automatically cleans abandoned reservations created by:
+
+* Server crashes
+* Interrupted requests
+* Failed transactions
+
+Stale reservations are validated and cleaned during startup.
+
+---
+
+# Breaking Changes
+
+## Global Slug Uniqueness
+
+Deployments containing duplicate slugs will not upgrade.
+
+Example:
+
+```text
+User 1:
+!nx9-dns-server
+
+User 3:
+!nx9-dns-server
+```
+
+Result:
+
+```text
+Upgrade aborted.
+
+Database upgrade aborted due to slug conflicts.
+```
+
+Conflicts must be resolved before migration can continue.
+
+---
+
+## Restore Collision Protection
+
+Restore operations now validate namespace integrity.
+
+Example:
+
+```text
+Existing slug:
+company
+
+Backup slug:
+company
+```
+
+Result:
+
+```text
+Restore aborted.
+Slug conflict detected.
+```
+
+No partial restore occurs.
+
+---
+
+# Pre-Upgrade Checklist
+
+Before upgrading:
+
+* Create backup
+* Verify backup integrity
+* Stop active traffic
+* Run diagnostics
+* Resolve namespace conflicts
+
+---
+
+# Step 1: Create Backup
+
+Full backup:
+
+```bash
+bzod backup
+```
+
+Manual backup:
+
+```bash
+tar czf bzod-backup.tar.gz data/
+```
+
+---
+
+# Step 2: Verify Backup
+
+Verify archive contents:
+
+```text
+users.db
+system.db
+
+users/
+```
+
+If upgrading from legacy versions:
+
+```text
+admin.db
+content.db
+analytics.db
+```
+
+should also be present.
+
+---
+
+# Step 3: Run Diagnostics
+
+Execute:
+
+```bash
+bzod doctor
+```
+
+Expected:
+
+```text
+Overall Status: HEALTHY
+```
+
+Verify:
+
+```text
+No namespace conflicts detected
+No ownership violations detected
+No registry corruption detected
+```
+
+---
+
+# Step 4: Stop Service
+
+Systemd:
+
+```bash
+sudo systemctl stop bzod
+```
+
+Docker:
+
+```bash
+docker compose down
+```
+
+---
+
+# Upgrade Procedure
+
+## Install New Version
+
+Build:
+
+```bash
+cargo build --release
+```
+
+Or install official release binary.
+
+---
+
+## Start BZOD
+
+```bash
+bzod serve
+```
+
+or:
+
+```bash
+docker compose up -d
+```
+
+---
+
+# Automatic Upgrade Actions
+
+During startup BZOD automatically performs:
+
+1. Database migration checks
+2. Namespace integrity validation
+3. Registry validation
+4. Stale reservation cleanup
+5. Global slug verification
+6. Schema migration execution
+
+---
+
+# Namespace Validation
+
+BZOD scans:
+
+```text
+legacy databases
+administrator databases
+tenant databases
+```
+
+for duplicate slugs.
+
+Example:
+
+```text
+Owner 1:
+hello
+
+Owner 3:
+hello
+```
+
+Result:
+
+```text
+Namespace conflict detected.
+Upgrade aborted.
+```
+
+---
+
+# Registry Validation
+
+BZOD validates:
+
+* Duplicate slug entries
+* Missing owners
+* Missing targets
+* Invalid target types
+* Invalid status values
+
+Allowed target types:
+
+```text
+url
+page
+```
+
+Allowed statuses:
+
+```text
+reserving
+active
+disabled
+```
+
+---
+
+# Post-Upgrade Validation

+
+```bash
+bzod doctor
+```
+
+Expected:
+
+```text
+Namespace Integrity: PASS
+Registry Integrity: PASS
+Ownership Integrity: PASS
+Database Integrity: PASS
+```
+
+---
+
+# Login Validation
+
+Verify:
+
+```text
+Administrator login succeeds
+User login succeeds
+```
+
+---
+
+# URL Validation
+
+Verify:
+

+https://example.com/abc123
+```
+
+redirects correctly.
+
+Expected:
+
+```http
+302 Found
+```
+
+or configured redirect behavior.
+
+---
+
+# Landing Page Validation
+
+Verify:
+
+```text
+https://example.com/p/demo
+```
+
+renders successfully.
+
+Verify:
+
+```text
+https://example.com/demo
+```
+
+redirects permanently:
+
+```http
+301 Moved Permanently
+```
+
+to:
+
+```text
+/p/demo
+```
+
+---
+
+# QR Validation

+```
+
+Content types:
+
+```text
+image/png
+image/svg+xml
+```
+
+Disabled resources:
+
+```http
+410 Gone
+```
+
+Missing resources:
+
+```http
+404 Not Found
+```
+
+---
+
+# Dashboard Validation
+
+Verify Administrator Dashboards:
+
+* URLs
+* Landing Pages
+* Analytics
+* QR Preview
+* PNG Download
+* SVG Download
+
+Verify Standard User Dashboards:
+
+* URLs
+* Landing Pages
+* Analytics
+* QR Preview
+* PNG Download
+* SVG Download
+
+Both should provide equivalent functionality except for administrator-only operations.
+
+---
+
+# Ownership Isolation Validation
+
+Verify:
+
+```text
+User A
+```
+
+cannot access:
+
+```text
+User B Analytics
+User B URLs
+User B Landing Pages
+User B Exports

+Duplicate slug detected.
+```
+
+Resolution:
+
+```text
+Rename or remove conflicting resources.
+Restart upgrade.
+```
+
+---
+
+## QR Codes Return 404
+
+Verify:
+
+```text
+global_slugs
+```
+
+contains the slug.
+
+Verify slug status:
+
+```text
+active
+```
+
+---
+
+## Landing Page Redirect Fails
+
+Verify:
+
+```text
+target_type = page
+```
+
+in:
+
+```text
+global_slugs
+```
+
+---
+
+## Ownership Errors
+
+Run:
+
+```bash
+bzod doctor
+```
+
+Verify ownership integrity passes.
+
+---
+
+# Upgrade Status
