# Isis Topology Verification

## Purpose

Admin §24.9 lane console that verifies 3D mesh topology via the real
three-d-pipelines `verifyTopology` (zero-faces / degenerate-faces /
non-manifold-edges / not-watertight / zero-volume detection). It loads example
meshes from `GET /v1/admin/isis/topology/examples` and verifies an arbitrary mesh
via `POST …/topology/verify`. It is admin-scoped and fails closed.

## Entry points

- Sibling quick-action from `/studio/isis/3d-post-processing`
- Studio index (`/studio`)
- Direct URL / bookmark (AAA entitlement required)

## Layout regions

`page.tsx` mounts `<ShellLayout active="studio">` (no breadcrumb panel) and three
panels: the workspace, the Route Map, and sibling quick-actions.

- **Header**: shell header
- **Workspace panel** (`data-isis-topology-verification-workspace`):
  - `<h1>` (`WorkspaceHeading`) "Isis Topology Verification Workspace"
  - Summary paragraph (`data-isis-topology-verification-summary`)
  - Example-mesh list (`data-topology-examples`, each
    `data-topology-example=<slug>` — clicking loads the mesh into the form)
  - Verify form (`data-topology-form`)
- **Route Map panel** (`data-isis-topology-verification-route-map`): `<h2>Route
  Map</h2>` over `STUDIO_ISIS_TOPOLOGY_VERIFICATION_ROUTE_MAP` (5 entries)
- **Sibling quick-actions panel**: `/studio/isis/3d-post-processing`, `/studio`

## States

- [ ] **Loading** — `data-topology-loading`
- [ ] **Unauthorized** — 401/403 admin-scope fail-closed;
      `data-topology-unauthorized`
- [ ] **Error** — non-OK or malformed examples; `data-topology-error`
- [ ] **Ready (form)** — examples present; mesh fields + checkboxes render
- [ ] **Result** — after a verify POST, `data-topology-report`
      (`data-topology-report-valid=valid|invalid`) listing each
      `data-topology-issue`; verify-time errors surface in
      `data-topology-report-status="error"`

## Interactions

### Verify form (`data-topology-form`)

- [ ] **Mesh fields** (`data-topology-field=<field>`) — the mesh vertices/indices
      (populated by loading an example or pasted manually)
- [ ] **Watertight** (`data-topology-watertight`, checkbox) — declared watertight
      flag on the mesh
- [ ] **Require watertight** (`data-topology-require-watertight`, checkbox) — gate
      the verdict on watertightness
- [ ] **Verify topology** (`data-topology-verify`, button; "Verifying…" while in
      flight) — `POST /v1/admin/isis/topology/verify`

### Example meshes

- [ ] **Load example** (`data-topology-example=<slug>`) — loads the example mesh
      into the verify form

### Route Map

- [ ] **Route-map articles** ×5

### Sibling quick-actions

- [ ] **Open Isis 3D Post-Processing workspace** →
      `/studio/isis/3d-post-processing`
- [ ] **Back to Studio workspace index** → `/studio`

## Data & contracts

- **Reads**: `GET /v1/admin/isis/topology/examples` (example meshes)
- **Writes**: `POST /v1/admin/isis/topology/verify` (verify a mesh; returns
  `{ valid, issues }`)
- **Realtime**: none
- **Caching**: client fetch on mount, `cache: 'no-store'`, `buildBffAuthHeaders()`
- **Auth/role check**: admin-scoped, fail-closed (401/403); route gated on
  signed-in + studio entitlement (AAA segment)
- **Component sources**:
  - `apps/oshun/web/src/components/studio/StudioIsisTopologyVerificationWorkspace.tsx`
  - `apps/oshun/web/src/components/studio/StudioIsisTopologyVerificationRouteMap.ts`

## Cross-references

- Studio overview: [`../../studio-overview.md`](../../studio-overview.md)
- AAA gating: `libs/isis/entitlements/src/studio-boundary.ts`
- Sibling routes:
  - [`studio-isis-3d-post-processing.md`](./studio-isis-3d-post-processing.md)
  - [`studio-isis-3d-result-management.md`](./studio-isis-3d-result-management.md)

## Open questions / known gaps

- [ ] No breadcrumb on this route — navigation is via sibling quick-actions
- [ ] Overlaps with `/studio/isis/3d-result-management`'s post-pipeline analyzer;
      confirm the responsibility split between standalone verification and the
      acceptance gate
