Multi-Tenant Architecture

Hierarchy

CopyOrganization (tenant boundary)
├── OrganizationMember (user ↔ org, role: OWNER|ADMIN|MEMBER)
├── Team
│   └── TeamMember (org_member ↔ team, role: ADMIN|MEMBER|VIEWER)
└── Resources scoped by: organization_id + team_id + user_id

Critical FK Pattern

Copy# TeamMember links to OrganizationMember, NOT User
class TeamMember(SQLModel, table=True):
    org_member_id: UUID = Field(foreign_key="organization_member.id")

Query Scoping (REQUIRED)

Copy# ALWAYS filter by organization
statement = select(Resource).where(
    Resource.organization_id == org_context.organization.id,
    Resource.deleted_at == None,  # noqa: E711
)

# Add team scope for team resources
statement = statement.where(Resource.team_id == team_context.team.id)

Settings Hierarchy

CopyOrganization (defaults)
    ↓ overrides
Team (if allow_team_customization)
    ↓ overrides
User (if allow_user_customization)
