# Isis Audio Generation

## 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`

## Open questions / known gaps

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