# Studio Hathor · Location Modeling

## Purpose

Admin lane console that assesses a single location record — condition, danger
level, atmosphere, services, demographics, economy, trade routes, districts, and
defenses — and returns scored diagnostics. The operator submits a JSON location
object and the lane returns the assessment scores.

## Entry points

- **Quick-action link from `/studio/hathor/character-modeling`** and
  **`/studio/hathor/domain-models`** (verify against those pages' sources)
- **Direct URL / bookmark** — yes; `alternates.canonical` set to
  `/studio/hathor/location-modeling`
- **Studio overview** — see
  [`../../studio-overview.md`](../../studio-overview.md)

## Layout regions

`page.tsx` renders inside `<ShellLayout active="studio">`:

- **Workspace** `<StudioHathorLocationModelingWorkspace />`
  (`data-hathor-location-modeling-workspace`):
  - `WorkspaceHeading` `<h1>` — "Hathor Location Modeling Workspace"
  - Summary `<p data-hathor-location-modeling-summary>`
  - **Location Assessment Lane** — `<h2 data-loc-lane-heading>`; holds the
    loading / unauthorized / error / form / result states
- **Route Map panel** `data-hathor-location-modeling-route-map` — `<h2>` "Route
  Map" listing the 5 `STUDIO_HATHOR_LOCATION_MODELING_ROUTE_MAP` entries
  (locations / landmarks / travel-routes / governance child paths)
- **Quick-action lane** — three `Link.quickAction` anchors: Character Modeling,
  Timeline Modeling, Back to Studio workspace index

## States

- [ ] **Loading** — `data-loc-loading` while the GET catalog request is in flight
- [ ] **Unauthorized (admin-scope 401/403)** — `data-loc-unauthorized`
- [ ] **Error** — `data-loc-error`
- [ ] **Ready (form)** — `data-loc-enums` enum hint + location textarea + submit
- [ ] **Result** — `data-loc-result` with `data-loc-headline` and
      `data-loc-scores`
- [ ] **Validation error** — `data-loc-assess-error`

## Interactions

### Location Assessment Lane

- [ ] **Location payload** — `<textarea data-loc-payload>`, JSON
      `{ location:{ locationId, name, condition, dangerLevel, atmosphere,
      services[], hasDemographics, economyActivity, tradeRoutes, districts[],
      defenses? } }`
- [ ] **Submit** — `<button data-loc-submit>` "Assess location" → POST
      `ASSESS_ENDPOINT`

### Route Map panel

- [ ] **Route entries** — verify match with
      `STUDIO_HATHOR_LOCATION_MODELING_ROUTE_MAP` (5 entries)

### Quick-action lane

- [ ] **"Open Hathor Character Modeling workspace"** → `/studio/hathor/character-modeling`
- [ ] **"Open Hathor Timeline Modeling workspace"** → `/studio/hathor/timeline-modeling`
- [ ] **"Back to Studio workspace index"** → `/studio`

## Data & contracts

- **Reads**: `GET /v1/admin/hathor/workbench-locations` (`LOC_ENDPOINT`; note the
  endpoint slug differs from the route slug — it reuses the workbench-locations
  admin backend) — the location enums catalog
- **Writes**: `POST /v1/admin/hathor/workbench-locations/assess`
  (`ASSESS_ENDPOINT`) with the location record
- **Realtime**: none
- **Caching**: client `fetch` on mount, `cache: 'no-store'`, `buildBffAuthHeaders()`
- **Auth/role check**: admin-scoped, fail-closed on 401/403; route additionally
  gated signed-in + studio by the BFF proxy

## Open questions / known gaps

- [ ] The GET/POST endpoints live under `workbench-locations`, not
      `location-modeling`. Confirm the shared backend is intentional.
- [ ] Hathor is `unconfirmed-v1` per `WALKTHROUGH/matrix/routes.csv`. Confirm
      whether the dedicated `/studio/hathor/` lane consoles ship at V1 or are
      internal-only.
