Last walked. 2026-05-29 automated runtime walk (Playwright headless) — render, /v1 data (2xx), console/page-errors, expected content, screenshot verified; live screen-reader, touch, offline, and telemetry-delivery checks pending a manual AT pass. Evidence: WALKTHROUGH/results/runtime-sweep-2026-05-29.md; body re-derived 2026-06-03 from current source (lane-console architecture)

Purpose#

Admin lane console for the @hathor/llm-npc WorldAwarenessManager spatial-perception engine. From the NPC's position and a seeded scene of objects and characters, the engine computes 3D distance, flags what lies inside the 120° visual field, drops anything beyond 50 m, sorts by distance, and surfaces the nearest character, the objects in reach, and any threats. Admin-scoped and fail-closed.

Entry points#

  • Direct URL / bookmark — /studio/hathor/npc-world-awareness; alternates.canonical is set.
  • Quick-action from siblings — this page links to the NPC Memory System lane.
  • Studio overview — see ../../studio-overview.md.

Layout regions#

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

  • Workspace (StudioHathorNpcWorldAwarenessWorkspace, data-hathor-npc-world-awareness-workspace):
    • <h1> WorkspaceHeading — "Hathor NPC World Awareness Workspace"
    • Summary <p data-hathor-npc-world-awareness-summary>
    • Catalog state, then the Seeded scene list (data-hathor-nwa-scene) and the perception form + result.
  • Route Map panel (<section data-hathor-npc-world-awareness-route-map>, <h2>Route Map</h2>): 5 entries from STUDIO_HATHOR_NPC_WORLD_AWARENESS_ROUTE_MAP (path + purpose).
  • Quick-action lane (className="quickAction" Links): NPC Memory System, Back to Studio workspace index.

States#

  • Loading — <p data-hathor-nwa-loading> "Loading perception engine…".
  • Unauthorized — data-hathor-nwa-unauthorized on 401/403 (admin-scope).
  • Error — data-hathor-nwa-error on a non-OK catalog response or network failure.
  • Ready (form) — the seeded scene list + data-hathor-nwa-perceive-form with the NPC position and reach inputs.
  • Result — data-hathor-nwa-result with data-hathor-nwa-nearest, data-hathor-nwa-threats, data-hathor-nwa-interactable, data-hathor-nwa-visible-count, and the per-object / per-character lists.
  • Validation error — data-hathor-nwa-perceive-error for non-numeric position/reach or a failed POST.

Interactions#

  • data-hathor-nwa-pos-x / -pos-y / -pos-z (inputs, aria-label="npc x/y/z") — the NPC position.
  • data-hathor-nwa-reach (input, aria-label="reach") — interactable reach in metres.
  • data-hathor-nwa-perceive-submit ("Run perception") — validates the coordinates and reach, then POSTs { npcPosition, npcOrientation, objects, characters, interactableMaxDistance } (objects/characters are the seeded scene); on 200 with a valid perception renders the read-out.
  • Route Map entries — verify against STUDIO_HATHOR_NPC_WORLD_AWARENESS_ROUTE_MAP (5 entries).
  • Quick-action links — NPC Memory System (/studio/hathor/npc-memory-system), Back to Studio (/studio).

Data & contracts#

  • Reads: GET /v1/admin/hathor/npc-world-awareness (catalog: limits, characterTypes, emotions).
  • Writes: POST /v1/admin/hathor/npc-world-awareness/perceive with the NPC position + seeded scene.
  • 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.

Cross-references#

Open questions / known gaps#

  • The scene (objects + characters) is seeded in the component; confirm whether operators should be able to supply a custom scene rather than only varying the NPC position and reach.
  • Hathor is unconfirmed-v1 per WALKTHROUGH/matrix/routes.csv; confirm whether the dedicated /studio/hathor/* admin lanes ship V1 or are internal-only.
