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 wires the real @isis/audio-generation computeFrameRms DSP via /v1/admin/isis/audio-generation: the operator supplies a generated audio signal's samples plus a frame size and gets back the per-frame RMS loudness envelope (peak + mean RMS). It is admin-scoped and fails closed.

Entry points#

  • Breadcrumb in-page: Studio → Isis Music Generation → Audio Generation
  • Sibling quick-actions from /studio/isis/music-generation, /studio/isis/text-to-audio, /studio/isis/3d-generation
  • Direct URL / bookmark (AAA entitlement required)

Layout regions#

page.tsx mounts <ShellLayout active="studio"> with a breadcrumb panel, the workspace, the Route Map, and sibling quick-actions.

  • Header: shell header
  • Breadcrumb panel (data-isis-audio-generation-breadcrumbs): Studio (link) → Isis Music Generation (link → /studio/isis/music-generation) → Audio Generation (aria-current="page")
  • Workspace panel (data-isis-audio-generation-workspace):
    • <h1> (WorkspaceHeading) "Isis Audio Generation Workspace"
    • Summary paragraph (data-isis-ag-summary)
    • Loudness-analyzer form (data-isis-ag-loudness-form)
  • Route Map panel (data-isis-audio-generation-route-map): <h2>Route Map</h2> over STUDIO_ISIS_AUDIO_GENERATION_ROUTE_MAP (6 entries)
  • Sibling quick-actions panel: /studio/isis/music-generation, /studio/isis/text-to-audio, /studio/isis/3d-generation, /studio

States#

  • Loading — outcome === null; data-isis-ag-loading "Loading loudness analyzer…"
  • Unauthorized — 401/403 admin-scope fail-closed; data-isis-ag-unauthorized
  • Error — non-OK or malformed catalog; data-isis-ag-error
  • Ready (form) — catalog present; samples + frame-size inputs render
  • Result — after a loudness POST, data-isis-ag-result shows data-isis-ag-peak (peak RMS) and data-isis-ag-mean (mean RMS); failures surface in data-isis-ag-loudness-error

Interactions#

Loudness-analyzer form (data-isis-ag-loudness-form)#

  • Samples (comma-separated) (data-isis-ag-field-samples, text input)
  • Frame size (data-isis-ag-field-frame, text input)
  • Analyze loudness (data-isis-ag-loudness-submit, submit) — POST /v1/admin/isis/audio-generation/loudness

Route Map#

  • Route-map articles ×6

Sibling quick-actions#

  • Open Isis Music Generation workspace → /studio/isis/music-generation
  • Open Isis Text-to-Audio workspace → /studio/isis/text-to-audio
  • Open Isis 3D Generation workspace → /studio/isis/3d-generation
  • Back to Studio workspace index → /studio

Data & contracts#

  • Reads: GET /v1/admin/isis/audio-generation (analyzer catalog)
  • Writes: POST /v1/admin/isis/audio-generation/loudness (returns { loudness: { peakRms, meanRms } })
  • Realtime: none
  • Caching: client fetch on mount, cache: 'no-store', buildBffAuthHeaders()
  • Auth/role check: admin-scoped, fail-closed (401/403); route gated on signed-in + studio entitlement (AAA segment)
  • Component sources:
    • apps/oshun/web/src/components/studio/StudioIsisAudioGenerationWorkspace.tsx
    • apps/oshun/web/src/components/studio/StudioIsisAudioGenerationRouteMap.ts

Cross-references#

Open questions / known gaps#

  • The analyzer measures loudness of pre-supplied samples; actual audio generation runs elsewhere — confirm where the generation request originates
