Phase 9 Plan 05: Schema-projected CRUD and atomic bulk delete Summary

Admin create and update fill only activation-bound fields, and bulk delete locks the scoped set so every selected row commits or none do.

Performance

• Duration: 25 min
• Started: 2026-09-24T17:20:57Z
• Completed: 2026-09-24T17:45:40Z
• Tasks: 3
• Files modified: 8

Accomplishments

• ProjectWritableFields keeps only schema fields bound to gorm columns at activation. id, timestamps, scope_id, ownership ids, and system flags never reach lagoon.Fill, even when the JSON key is cased or nested.
• Create and update run Fill, BeforeValidate, then lagoon.Validate (YAML required merged onto Rules()) before persistence. Validation errors are D-10 validation_failed with field messages. A missing Fillable/Rules method or a Validate provider error does not insert.
• GET/POST/PUT/DELETE /_admin/api/v1/{vendor}/{plugin}/{controller} record routes sit behind the backend group and protect, so a forbidden caller is 403 before the id or body is read. Show and update of a missing or out-of-scope id share one not_found body. Delete of an absent id returns deleted: 0 and does not run hooks.
• Create, update, and delete call the matching FormBefore* / FormAfter* hook once around the GORM callbacks, inside one transaction. A hook error rolls back and the response is Server error without the hook text.
• POST .../bulk-delete rejects an empty ids list with 422, dedupes, sorts by primary key, and locks the scoped rows FOR UPDATE. A wholly absent selection returns deleted: 0. A mixed present/absent selection is 409 and rolls back. Concurrent identical requests delete each row once.

TDD Gate Compliance

Each task has a test(09-05) commit that failed on the named assertion, then a feat(09-05) commit. gsd_run check tdd-red-evidence returned RED_EVIDENCE_OK for TestCRUDFillValidate, TestCRUDRecordRoutes, and TestBulkDeleteEmpty before the matching implementation. No refactor commit was needed.

Plan metadata: included in the docs commit for this summary

Files Created/Modified

• cabana/crud.go - CRUDService, writable projection, record lifecycle, and locked bulk delete
• cabana/http.go - show, create, update, delete, and bulk-delete routes after the permission check
• cabana/registry.go - binds writable fields while compiling a controller
• cabana/contracts.go - WritableField on the compiled controller
• cabana/crud_test.go - Fill/Validate, projection, protected fields, and capability tests
• cabana/crud_lifecycle_test.go - routes, permissions, scope, hooks, and rollback
• cabana/bulk_test.go - empty, duplicate, order, retry, rollback, and concurrency
• pact/capabilities.go - FormAfterCreate, FormAfterUpdate, FormBeforeDelete, FormAfterDelete

Decisions Made

• Activation binds a scalar form field to the gorm column of the same name. Protected columns are omitted from that list rather than copied and then dropped.
• YAML required: true is appended to model Rules() and never replaces a stricter rule. Validate reads the model after BeforeValidate, so a hook can still clear a value and fail required.
• Show and update answer missing and out-of-scope ids with the same 404. Delete answers both with deleted: 0 so a retry of a completed delete does not rerun hooks and does not reveal scope.
• Bulk delete uses ListExtendQuery. If the locked row count is zero, the result is deleted: 0. If it is greater than zero but short of the normalized ids, the response is conflict and the transaction rolls back.
• Hook and database errors become cabana: controller <id> failed. The HTTP body stays Server error.

Deviations from Plan

Auto-fixed Issues

1. [Rule 2 - Missing Critical] Added the After and delete controller hooks

• Found during: Task 2 (scoped record lifecycle)
• Issue: D-13 named FormBeforeCreate and FormBeforeUpdate only. The plan also requires Before/After hooks for create, update, and delete, once each.
• Fix: Added FormAfterCreate, FormAfterUpdate, FormBeforeDelete, and FormAfterDelete next to the existing pact hooks and call each implemented hook inside the transaction.
• Files modified: pact/capabilities.go, cabana/crud.go
• Verification: TestCRUDHooks and TestCRUDRollback
• Committed in: 94814d9 (interfaces) and e3e1c25 (calls)

2. [Rule 2 - Missing Critical] Stored the writable binding on the compiled controller

• Found during: Task 1 (Fill/Validate)
• Issue: The plan's file list did not include contracts.go, but the binding has to survive activation and be readable without reflecting over request keys.
• Fix: Added Writable []WritableField and fill it from BindWritableFields during compileRegistry.
• Files modified: cabana/contracts.go, cabana/registry.go
• Verification: TestCRUDWritableProjection
• Committed in: 1e14da7 and 578bdc8

---

Total deviations: 2 auto-fixed (2 missing critical) Impact on plan: Both were required to enforce the mass-assignment and lifecycle contracts. No new route family or dependency.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Ready for 09-06. Record and bulk routes are in place for every compiled controller that exposes NewRecord, Fillable, and Rules. Relation link/unlink and settings upsert are still later plans. ADMIN-04 stays pending in REQUIREMENTS.md because 09-06, 09-07, 09-08, 09-09, 09-10, and 09-12 also declare it.

go test ./cabana -run '^(TestCRUD|TestBulkDelete)' -count=1 passed.
