# 02 — Tenancy Model
Approach
- Single database, row-level scoping via `tenant_id` on tenant-owned tables.
- Global scope (BelongsToTenant trait) for all tenant-owned models; bypass for Super Admin.
- Policies enforce `tenant_admin` and `member` roles; guest upload uses signed, limited-scope tokens.
Keys & Indexes
- Composite uniques include `tenant_id` (e.g., `events`: unique `tenant_id, slug`).
- Foreign keys cascade/delete or null-on-delete based on data retention needs.
Tenant Resolution
- Tenant Admin PWA: resolve from authenticated token claim (`tenant_id`).
- Guest PWA/custom domains: resolve from host/subdomain; map to event and tenant.
Impersonation
- Super Admin can impersonate tenant users; all actions audited with actor + target + reason.
Backups & Export
- Backups include tenant partitions by `tenant_id`.
- Export endpoints provide per-tenant data bundles (photos metadata + links), respecting rate limits.
