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 that packs a dialogue context window — running the real context-budget packer that decides which candidate context items fit a token budget, which are included, and which overflow (with reasons). The operator submits a JSON payload of candidate items and the lane returns the packed window.

Entry points#

  • Quick-action link from /studio/hathor/npc-world-awareness (verify against that page's source)
  • Direct URL / bookmark — yes; alternates.canonical set to /studio/hathor/npc-dialogue-generation
  • Studio overview — see ../../studio-overview.md

Layout regions#

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

  • Workspace <StudioHathorNpcDialogueGenerationWorkspace /> (data-hathor-npc-dialogue-generation-workspace):
    • WorkspaceHeading <h1> — "Hathor NPC Dialogue Generation Workspace"
    • Summary <p data-hathor-npc-dialogue-generation-summary>
    • Live Context-Window Packer lane — <h2 data-ctx-heading> (lane data-ctx-lane); holds the loading / unauthorized / error / form / result states
  • Route Map panel data-hathor-npc-dialogue-generation-route-map — <h2> "Route Map" listing the 5 STUDIO_HATHOR_NPC_DIALOGUE_GENERATION_ROUTE_MAP entries (profiles / dialogues / contexts / governance child paths)
  • Quick-action lane — two Link.quickAction anchors: NPC World Awareness, Back to Studio workspace index

States#

  • Loading — data-ctx-loading while the GET catalog request is in flight
  • Unauthorized (admin-scope 401/403) — data-ctx-unauthorized
  • Error — data-ctx-error
  • Ready (form) — candidate-items textarea + submit
  • Result — data-ctx-result with data-ctx-used (budget used), data-ctx-items (per-item data-ctx-item-row carrying data-item / data-included), data-ctx-overflow (with data-ctx-reason)
  • Validation error — data-ctx-pack-error

Interactions#

Live Context-Window Packer lane#

  • Candidate items — <textarea data-ctx-payload>
  • Submit — <button data-ctx-submit> "Pack context window" → POST CTX_PACK_ENDPOINT

Route Map panel#

  • Route entries — verify match with STUDIO_HATHOR_NPC_DIALOGUE_GENERATION_ROUTE_MAP (5 entries)

Quick-action lane#

  • "Open Hathor NPC World Awareness workspace" → /studio/hathor/npc-world-awareness
  • "Back to Studio workspace index" → /studio

Data & contracts#

  • Reads: GET /v1/admin/hathor/npc-dialogue-generation (CTX_ENDPOINT) — the packer catalog (budget defaults)
  • Writes: POST /v1/admin/hathor/npc-dialogue-generation/pack (CTX_PACK_ENDPOINT) with the candidate items
  • 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

Cross-references#

Open questions / known gaps#

  • Hathor is unconfirmed-v1 per WALKTHROUGH/matrix/routes.csv. Confirm whether the dedicated /studio/hathor/ lane consoles ship at V1 or are internal-only.
  • The lane packs context but does not itself generate dialogue text; confirm where the downstream generation step lives.
