# Specialist Report — agent-feature (AssetType API2 endpoints)

Spec: `docs/specs/20260703-113641-agent-feature.md`

## Summary

Added three project-scoped AssetType endpoints to API2, following the established
`routes → controller → validator → service` layering and mirroring the sibling
SystemType feature (`src/api/v2/projects/commissioning/systemTypes/`):

- `POST   /api/v2/projects/{projectId}/asset-types`
- `GET    /api/v2/projects/{projectId}/asset-types/{assetTypeId}`
- `GET    /api/v2/projects/{projectId}/asset-types`

The endpoints call existing `xyz` stored functions (`fn_GetAssetTypeList`,
`fn_GetAssetType`, `fn_InsertAssetType`) and map the per-project unique-constraint
violations on `Name` / `Code` to `409 Conflict`.

## Revision addressed (human feedback: "fix the api test fails")

**Root cause:** The AssetType e2e spec set up a project but no `CommissioningWorkflow`.
`xyz."AssetType"."CommissioningWorkflowId"` is `NOT NULL`, and `fn_InsertAssetType`
resolves it to the project's first (default) workflow, raising
`No CommissioningWorkflow exists for project %` when none is present. Every POST (and
the GET-by-id / uniqueness tests that depend on a created asset type) therefore failed
with a 500.

**Fix:** In the top-level `before` hook of `test/e2e/api/asset.types.e2e.spec.ts`,
create a `CommissioningWorkflow` for the test project before any asset type is
inserted — exactly as the SystemType e2e spec does. No production code changed; the
service/controller/validator already match the real DB function signatures and
constraint names (verified against the `postgres` schema repo).

## Files changed

- `src/api/v2/projects/assetTypes/asset.types.routes.ts` — routes + swagger, `mergeParams`, RBAC (`PROJECT_VIEW` for reads, `PROJECT_EDIT` for create).
- `src/api/v2/projects/assetTypes/asset.types.controller.ts` — list / get / create controllers.
- `src/api/v2/projects/assetTypes/asset.types.validator.ts` — projectId/assetTypeId UUID validation, create-body validation (`name`, `code` non-blank).
- `src/services/asset.types.service.ts` — DB access via stored functions; maps `AssetType_ProjectShardId_Name_key` / `AssetType_ProjectShardId_Code_key` violations to `ResourceConflictError` (409).
- `src/api/v2/api.v2.routes.ts` — wires `assetTypesRouter` at `/:projectId/asset-types`.
- `src/swagger.components.schemas.json` — added `AssetType` component schema (referenced via `$ref`, not inlined).
- `test/unit/api/v2/assetTypes/asset.types.controller.spec.ts` — unit tests (7 passing).
- `test/e2e/api/asset.types.e2e.spec.ts` — e2e tests; **updated** to seed a CommissioningWorkflow in `before` (the revision fix).
- `test/e2e/util/db-helper.ts` — added `getAssetTypeById`, `getAssetTypesByProject`, `cleanupProjectAssetTypes` helpers.

## Verification

- `npx tsc --noEmit` — clean.
- Unit tests (`test/unit/api/v2/assetTypes/asset.types.controller.spec.ts`) — 7 passing.
- E2E could not be run in this environment (no local Postgres/Citus, mock server, or
  TLS certs); the pipeline runs the e2e suite against the provisioned DB. The failing
  behaviour was diagnosed against the actual `postgres` schema repo and the fix mirrors
  the proven SystemType e2e setup.

## Deviations from spec

- The spec's risk note ("the existing AssetType table has no 'Code' column") is
  resolved in the DB layer: the `postgres` repo already adds the nullable `Code` column
  (`118_xyz_asset_type.sql`) and per-project unique constraints on `Name` and `Code`
  (`083_xyz_asset_type_name_code_unique.sql`). No API-side workaround was needed.

## Open questions for the reviewer

- Create does not accept a `commissioningWorkflowId`; `fn_InsertAssetType` defaults each
  AssetType to the project's first workflow. Confirm this default is the intended v1
  behaviour (the spec lists workflow association as out of scope).
- List endpoint returns a flat, `Name`-ordered array (no pagination/filtering), per the
  "Out of scope" section.
