# Studio Hathor · Narrative Theory Tooling

## Purpose

Admin lane console for the real `@hathor/narrative` quest `ConditionEvaluator`.
Given a game-state context and a set of quest/dialogue gating conditions, it
evaluates each one (type + operator + value, with optional negate) and combines
them with AND or OR to show exactly when a narrative branch unlocks. Admin-scoped
and fail-closed.

## Entry points

- **Quick-action link from `/studio/hathor/game-design-theory-mda`** (this page
  links out to game-design-theory-mda)
- **Aggregator embed**: `StudioHathorNarrativeApiWorkspace` mounts this workspace
  inline as its "Narrative Theory Tooling Lane"
- **Direct URL / bookmark** — yes; `alternates.canonical` set
- **Studio overview** — see
  [`../../studio-overview.md`](../../studio-overview.md)

## Layout regions

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

- **Workspace** `<section data-hathor-narrative-theory-tooling-workspace>`:
  - `<h1>` (WorkspaceHeading) "Hathor Narrative Theory Tooling Workspace"
  - Summary `<p data-hathor-narrative-theory-tooling-summary>`
  - The evaluate form lane: `data-hathor-ntt-evaluate-form`
- **Route Map panel**
  (`data-hathor-narrative-theory-tooling-route-map`): `<h2>` "Route Map" + 5
  entries from `STUDIO_HATHOR_NARRATIVE_THEORY_TOOLING_ROUTE_MAP`
- **Quick-action lane**: two `Link.quickAction` anchors — Game Design Theory
  (MDA), Back to Studio workspace index

## States

- [ ] **Loading** — `<p data-hathor-ntt-loading>`
- [ ] **Unauthorized** — `data-hathor-ntt-unauthorized` on 401/403 (admin Hathor
      scope required); fail-closed
- [ ] **Error** — `data-hathor-ntt-error` on non-OK GET / malformed catalog
- [ ] **Ready (form)** — `data-hathor-ntt-evaluate-form` once the catalog loads
- [ ] **Result** — `data-hathor-ntt-result` after a 200 evaluate;
      `data-hathor-ntt-evaluate-error` for invalid JSON / non-200

## Interactions

### Workspace body (evaluate form lane)

- [ ] **Game-state context (JSON)** — `<textarea data-hathor-ntt-context>`
      (aria-label "context json")
- [ ] **Conditions (JSON array)** — `<textarea data-hathor-ntt-conditions>`
      (aria-label "conditions json"); each
      `{ type, target, operator, value, value2?, negate?, description? }`
- [ ] **Combine with** — `<select data-hathor-ntt-logic>` (AND / OR)
- [ ] **Evaluate conditions** —
      `<button data-hathor-ntt-evaluate-submit type="submit">` → POST
      `/v1/admin/hathor/narrative-theory-tooling/evaluate`
- [ ] **Result** — `data-hathor-ntt-verdict` plus a
      `data-hathor-ntt-conditions-list` of `data-hathor-ntt-condition-item` rows

### Route Map panel

- [ ] **5 route entries** — verify match with
      `STUDIO_HATHOR_NARRATIVE_THEORY_TOOLING_ROUTE_MAP`

### Quick-action lane

- [ ] **"Open Hathor Game Design Theory (MDA) workspace"** (→
      `/studio/hathor/game-design-theory-mda`)
- [ ] **"Back to Studio workspace index"** (→ `/studio`)

## Data & contracts

- **Reads**: GET `/v1/admin/hathor/narrative-theory-tooling` on mount
- **Writes**: POST `/v1/admin/hathor/narrative-theory-tooling/evaluate`
- **Realtime**: none
- **Caching**: client `fetch` on mount, `cache: 'no-store'`; `buildBffAuthHeaders`
- **Auth/role check**: admin-scoped fail-closed (401/403); behind the signed-in
  + studio proxy gate

## Open questions / known gaps

- [ ] Hathor is `unconfirmed-v1` per `WALKTHROUGH/matrix/routes.csv`. Confirm
      whether the dedicated `/studio/hathor/*` admin lane consoles ship in V1.
- [ ] The lane exposes the quest `ConditionEvaluator` only; despite the
      "narrative theory" name, no Aristotelian/MDA framework tooling renders —
      confirm whether broader theory analysers are planned for this route.
- [ ] Route Map advertises `frameworks/`, `arcs/`, `beats/`, and `governance/`
      sub-routes with no `page.tsx` yet.
