# Studio · Yemaya · Project Creation and Types

## Purpose

Admin lane console for project-creation validation. The Project Creation
Operations Lane wires the real `@yemaya/projects` Zod schemas via
`/v1/admin/yemaya/project-creation-types`: list the supported project types and
statuses, and validate a create-project payload against the canonical
`CreateProjectSchema` before creation.

Note: the URL segment is `project-creation-and-types` but the component / route
map / endpoint identifiers use `ProjectCreationTypes` /
`project-creation-types` (without "and").

## Entry points

- No breadcrumb panel on this page.
- Reachable from the Studio index and from the Project Workspaces quick-action
  (which links here).
- Direct URL / bookmark (signed-in + studio entitlement).

## Layout regions

`page.tsx` renders `ShellLayout active="studio"` and:

- **Workspace panel** (`StudioYemayaProjectCreationTypesWorkspace`,
  `data-yemaya-project-creation-types-workspace`):
  - `<h1>` "Yemaya Project Creation and Types Workspace" (`WorkspaceHeading`).
  - Summary paragraph (`data-yemaya-project-creation-types-summary`).
  - **Project Creation Operations Lane**
    (`data-yemaya-project-creation-types-operations-lane`) — `<h2>` "Project
    Creation Operations Lane" + the real-backed form lane (loading /
    unauthorized / error / ready-form / result, see States).
- **Route Map panel** (`data-yemaya-project-creation-types-route-map`): `<h2>`
  "Route Map" + five `STUDIO_YEMAYA_PROJECT_CREATION_TYPES_ROUTE_MAP` entries.
- **Quick-action panel**: two `quickAction` links.

## States

- [ ] **Loading** — `data-yemaya-pct-loading` "Loading project types…" while the
      GET catalog fetch is in flight.
- [ ] **Unauthorized** — `data-yemaya-pct-unauthorized` "Access restricted." on a
      401/403 admin-scope failure (fail-closed).
- [ ] **Error** — `data-yemaya-pct-error` "Could not load the project types." on a
      non-OK / malformed catalog response.
- [ ] **Ready-form** — `data-yemaya-pct-form` once the catalog resolves;
      `data-yemaya-pct-types` lists project types + statuses.
- [ ] **Result** — `data-yemaya-pct-result` with `data-yemaya-pct-verdict`
      (valid / N issues) and a `data-yemaya-pct-issues` list; or a validation
      message `data-yemaya-pct-validate-error`.

## Interactions

### Validation form (`data-yemaya-pct-form`)

- [ ] **Create-project payload (JSON)** — `textarea` `data-yemaya-pct-project`
      (aria-label "create project json"); must parse to JSON.
- [ ] **Submit** — `button` `data-yemaya-pct-submit` "Validate payload" → POST
      `/v1/admin/yemaya/project-creation-types/validate` with `{ project }`.

### Route map

`data-yemaya-project-creation-types-route-map` — five entries:

- [ ] `/studio/yemaya/project-creation-and-types`
- [ ] `/studio/yemaya/project-creation-and-types/templates/[templateId]`
- [ ] `/studio/yemaya/project-creation-and-types/types/[typeId]`
- [ ] `/studio/yemaya/project-creation-and-types/revisions/[revisionId]`
- [ ] `/studio/yemaya/project-creation-and-types/governance/[gateId]`

### Quick actions

- [ ] **"Open Yemaya Project Workspaces workspace"** →
      `/studio/yemaya/project-workspaces`.
- [ ] **"Back to Studio workspace index"** → `/studio`.

## Data & contracts

- **Reads**: GET `/v1/admin/yemaya/project-creation-types` (catalog:
  `projectTypes`, `projectStatuses`) on mount.
- **Writes**: POST `/v1/admin/yemaya/project-creation-types/validate`.
- **Realtime**: none.
- **Caching**: client fetch on mount, `cache: 'no-store'`,
  `buildBffAuthHeaders()`.
- **Auth/role check**: admin-scoped fail-closed (401/403 → unauthorized state)
  behind the proxy studio gate.

## Open questions / known gaps

- [ ] The URL segment includes "and" but the component / route-map / endpoint
      identifiers omit it — confirm canonical naming.
- [ ] The Route Map advertises templates / types / revisions / governance
      sub-routes that the live validation lane does not expose.
