# Controller Classification

Phase 8 classifications:

- `canonical`: v2 controller using FormRequest, Resource/ApiResponse, SchoolContext, and contracts.
- `adapter`: legacy-compatible route that delegates to contracts and preserves response shape.
- `deprecated`: still reachable with replacement route and sunset target.
- `remove`: not routed, removal ticket required.
- `extension`: Islamic Sunday School-specific controller behind domain-profile middleware.

No controller should remain `unknown` after the route inventory is reviewed. Unknown is not a status. It is a confession.
