# Studio Hathor · Lore Validation Timeline

## Purpose

Admin lane console for the `@hathor/validation` TimelineValidator. The single
validate lane submits a set of historical events and checks temporal integrity —
events occurring before a declared cause (or after a declared effect), durations
that end before they start, and (opt-in) large gaps between consecutive events.
Admin-scoped and fail-closed.

## Entry points

- **Direct URL / bookmark** — `/studio/hathor/lore-validation-timeline`;
  `alternates.canonical` is set.
- **Quick-action from siblings** — the Lore Validation Causality lane links
  here; this page links out to NPC Platform Integrations.
- **Studio overview** — see
  [`../../studio-overview.md`](../../studio-overview.md).

## Layout regions

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

- **Workspace** (`StudioHathorLoreValidationTimelineWorkspace`,
  `data-hathor-lore-validation-timeline-workspace`):
  - `<h1>` `WorkspaceHeading` — "Hathor Lore Validation Timeline Workspace"
  - Summary `<p data-hathor-lore-validation-timeline-summary>`
  - The catalog state (`data-hathor-lvt-catalog`), then the events form (with
    gap toggle + threshold), pending submit state, validation errors, and
    result.
- **Route Map panel**
  (`<section data-hathor-lore-validation-timeline-route-map>`,
  `<h2>Route Map</h2>`): 5 entries from
  `STUDIO_HATHOR_LORE_VALIDATION_TIMELINE_ROUTE_MAP` (path + purpose).
- **Quick-action lane** (`data-hathor-lvt-quick-actions`,
  `data-hathor-lvt-quick-action-count="2"`): NPC Platform Integrations
  (`data-hathor-lvt-quick-action="npc-platform-integrations"`) and Back to
  Studio workspace index (`data-hathor-lvt-quick-action="studio-index"`).

## States

- [x] **Loading** — `<p data-hathor-lvt-loading>` "Loading timeline validator…".
- [x] **Unauthorized** — `data-hathor-lvt-unauthorized` on 401/403
      (admin-scope).
- [x] **Error** — `data-hathor-lvt-error` on a non-OK catalog response or
      network failure.
- [x] **Ready (form)** — `data-hathor-lvt-validate-form` with
      `data-hathor-lvt-form-state="idle"`, the events textarea, the gap toggle,
      and the gap-threshold input.
- [x] **Pending submit** — `data-hathor-lvt-form-state="validating"` and
      `data-hathor-lvt-submit-state="validating"`; submit is disabled with
      `aria-disabled="true"` and `aria-busy="true"` until the BFF response
      returns.
- [x] **Result** — `data-hathor-lvt-result` with `data-hathor-lvt-valid`,
      `data-hathor-lvt-counts` (events / errors / warnings / info), and
      `data-hathor-lvt-issues` rows (or `data-hathor-lvt-clean`).
- [x] **Validation error** — `data-hathor-lvt-validate-error` for malformed
      JSON, an empty array, an invalid threshold, or a failed POST.

## Interactions

- [x] **`data-hathor-lvt-events`** (textarea, `aria-label="events json"`) — edit
      the events JSON array
      (`{ id, name, year, causes?, effects?, duration? }`).
- [x] **`data-hathor-lvt-check-gaps`** (checkbox) — toggle gap detection.
- [x] **`data-hathor-lvt-gap-threshold`** (input, `aria-label="gap threshold"`)
      — the gap threshold in years (sent only when gap detection is on).
- [x] **`data-hathor-lvt-validate-submit`** ("Validate timeline") — parses the
      JSON and POSTs `{ events, checkGaps, gapThresholdYears? }`; on 200 with a
      valid `result` renders the verdict.
- [x] **Route Map entries** — verify against
      `STUDIO_HATHOR_LORE_VALIDATION_TIMELINE_ROUTE_MAP` (5 entries).
- [x] **Quick-action links** — NPC Platform Integrations
      (`/studio/hathor/npc-platform-integrations`), Back to Studio (`/studio`).

## Data & contracts

- **Reads**: `GET /v1/admin/hathor/lore-validation-timeline` (catalog:
  `issueCodes`, `defaultGapThresholdYears`), rendered as
  `data-hathor-lvt-catalog`.
- **Writes**: `POST /v1/admin/hathor/lore-validation-timeline/validate` with the
  events + gap flags. The happy path returns `{ ok: true, result }`; invalid
  events return BFF 400 `reason` strings such as `invalid_event`, which the lane
  surfaces in `data-hathor-lvt-validate-error`.
- **Realtime**: none.
- **Caching**: client fetch on mount, `cache: 'no-store'`,
  `buildBffAuthHeaders()`, `AbortController` on unmount.
- **Auth**: admin-scoped, fail-closed (401/403 → unauthorized); route is behind
  the signed-in + studio proxy gate.

## E2E coverage

- [`apps/oshun/web/e2e/studio-hathor-lore-validation-timeline.spec.ts`](../../../../apps/oshun/web/e2e/studio-hathor-lore-validation-timeline.spec.ts)
  — signed-in admin route; real Hathor timeline-validation BFF catalog and
  validate calls; seeded `TIMELINE_ORDER_VIOLATION`; opt-in
  `TIMELINE_GAP_DETECTED`; malformed JSON / empty array / invalid threshold
  zero-POST branches; live BFF `invalid_event` 400 detail; catalog
  loading/error; pending submit lockout; non-admin fail-closed state; anonymous
  redirect; route-map and quick-action anchors; automated 44px checks for the
  main editable controls and quick actions; shared axe gate.
- Supporting route contract coverage:
  `apps/oshun/bff/src/__tests__/admin-hathor-lore-validation-timeline-route.test.ts`
  covers auth/scope, issue-code catalog, clean order, order violation, invalid
  duration, gap detection, and BFF 400 payload validation.

## Open questions / known gaps

- [x] Hathor is confirmed in V1 per `WALKTHROUGH/matrix/routes.csv` and
      `WALKTHROUGH/matrix/coverage.md` (product-owner confirmation recorded
      2026-05-29 for Bellona / Hathor / Neith).
- [ ] Manual screen-reader pass remains for the live browser surface; automated
      axe and touch-target coverage now pass for the route-level controls.
