Phase 1 implementation includes: Database: - schema.sql with tables for tenants, domains, settings, branding, streams, users, subscriptions, plans, invoices, viewer_stats Core Classes (src/Core/): - Database.php: PDO wrapper with singleton pattern - TenantResolver.php: Domain-to-tenant resolution with fallback Tenant Classes (src/Tenant/): - TenantManager.php: CRUD operations for tenants - TenantSettingsManager.php: DB-based settings per tenant Configuration: - config.example.php: Template for database/stripe/mail config - bootstrap.php: Initializes multi-tenant environment - .gitignore: Excludes config.php and cache files Integration: - SettingsManager.php: Added saas_features toggles (all off by default) - index.php: Uses getSiteConfig() from bootstrap when multi-tenant enabled, falls back to legacy hardcoded domains when disabled All SaaS features are disabled by default (saas_features.multi_tenant_enabled = false), ensuring zero breaking changes to existing installations.
