# Studio · Yemaya · Core

## Purpose

Aggregator workspace that composes the Yemaya core control-plane admin lanes —
the API console, the CLI console, the Studio Web aggregator, and the Workers
aggregator — under a four-card capability summary. It issues no `/v1` fetch of
its own; each embedded lane runs its own real-backed engine.

## Entry points

- Breadcrumb chain on this page: **Studio › Yemaya Studio Web › Core**.
- Reachable from the Studio index and from sibling Yemaya routes.
- Direct URL / bookmark (signed-in + studio entitlement).

## Layout regions

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

- **Breadcrumbs panel** (`data-yemaya-core-breadcrumbs`): Studio › Yemaya Studio
  Web › Core.
- **Workspace panel** (`StudioYemayaCoreWorkspace`,
  `data-yemaya-core-workspace`):
  - `<h1>` "Yemaya Core Workspace" (`WorkspaceHeading`).
  - Summary paragraph (`data-yemaya-core-summary`).
  - **Capability Summary** (`data-yemaya-core-capability-summary`): `<h2>` + four
    cards — Core Service Control Plane, API and CLI Execution Governance, Studio
    Runtime and Worker Operations, Security and Parity.
  - **API Lane** (`data-yemaya-core-api-lane`) — embedded
    `StudioYemayaApiWorkspace`.
  - **CLI Lane** (`data-yemaya-core-cli-lane`) — embedded
    `StudioYemayaCliWorkspace`.
  - **Studio Web Lane** (`data-yemaya-core-studio-web-lane`) — embedded
    `StudioYemayaStudioWebWorkspace` (itself an aggregator; see
    [`studio-yemaya-studio-web.md`](./studio-yemaya-studio-web.md)).
  - **Workers Lane** (`data-yemaya-core-workers-lane`) — embedded
    `StudioYemayaWorkersWorkspace` (itself an aggregator; see
    [`studio-yemaya-workers.md`](./studio-yemaya-workers.md)).
- **Route Map panel** (`data-yemaya-core-route-map`): `<h2>` "Route Map" + six
  `STUDIO_YEMAYA_CORE_ROUTE_MAP` entries.
- **Quick-action panel**: five `quickAction` links.

## States

Per embedded lane (this page has no fetch of its own):

- [ ] **API Lane** — its own loading / unauthorized / error / ready / result
      states.
- [ ] **CLI Lane** — its own lane states.
- [ ] **Studio Web Lane** — nested aggregator; see
      [`studio-yemaya-studio-web.md`](./studio-yemaya-studio-web.md).
- [ ] **Workers Lane** — nested aggregator; see
      [`studio-yemaya-workers.md`](./studio-yemaya-workers.md).
- [ ] **Capability Summary** — static four-card panel, always rendered.

## Interactions

### Breadcrumbs

- [ ] **"Studio"** (link) → `/studio`
- [ ] **"Yemaya Studio Web"** (link) → `/studio/yemaya/studio-web`
- [ ] **"Core"** (current page) — `aria-current="page"`.

### Embedded lanes

- [ ] **API Lane** — `StudioYemayaApiWorkspace`.
- [ ] **CLI Lane** — `StudioYemayaCliWorkspace`.
- [ ] **Studio Web Lane** — `StudioYemayaStudioWebWorkspace`; see
      [`studio-yemaya-studio-web.md`](./studio-yemaya-studio-web.md).
- [ ] **Workers Lane** — `StudioYemayaWorkersWorkspace`; see
      [`studio-yemaya-workers.md`](./studio-yemaya-workers.md).

### Route map

`data-yemaya-core-route-map` — six entries:

- [ ] `/studio/yemaya/core`
- [ ] `/studio/yemaya/core/api/[serviceId]`
- [ ] `/studio/yemaya/core/cli/[commandId]`
- [ ] `/studio/yemaya/core/runtime/[runtimeId]`
- [ ] `/studio/yemaya/core/parity/[parityId]`
- [ ] `/studio/yemaya/core/governance/[policyId]`

### Quick actions

- [ ] **"Open Yemaya API workspace"** → `/studio/yemaya/api`.
- [ ] **"Open Yemaya CLI workspace"** → `/studio/yemaya/cli`.
- [ ] **"Open Yemaya Studio Web workspace"** → `/studio/yemaya/studio-web`.
- [ ] **"Open Yemaya Workers workspace"** → `/studio/yemaya/workers`.
- [ ] **"Back to Studio workspace index"** → `/studio`.

## Data & contracts

- **Reads / Writes**: none at the aggregator boundary; each embedded lane issues
  its own admin GET catalog + POST verb.
- **Realtime**: none.
- **Caching**: delegated to the embedded lanes (client fetch on mount,
  `cache: 'no-store'`).
- **Auth/role check**: admin-scoped fail-closed inside each lane, behind the
  proxy studio gate.

## Open questions / known gaps

- [ ] Core embeds two further aggregators (Studio Web, Workers), each of which
      embeds more lanes — verify the intended composition depth.
- [ ] The Route Map advertises api / cli / runtime / parity / governance
      sub-routes; confirm whether those dynamic children exist as `page.tsx`
      files yet.
