# Studio · Yemaya · Voice/Video Communication

## Purpose

Admin lane console wired to the `@yemaya/av-sync` timing/DSP primitives:
diagnose a session's audio/video alignment — clock drift, audio frame duration,
signal level (dB), and jitter-buffer depth — from the session's timing
parameters.

## Entry points

- Studio index quick-actions.
- No breadcrumb panel on this page.
- This page links out to `/studio/yemaya/cursor-and-selection-sharing`.
- Embedded as a lane inside `/studio/yemaya/studio-desktop`.
- Direct URL / bookmark (signed-in + studio entitlement).

## Layout regions

`page.tsx` renders `ShellLayout active="studio"` and:

- **Workspace panel** (`StudioYemayaVoiceVideoCommunicationWorkspace`,
  `data-yemaya-voice-video-communication-workspace`):
  - `<h1>` "Yemaya Voice/Video Communication Workspace".
  - Summary `<p data-yemaya-voice-video-communication-summary>` (diagnose A/V
    alignment with the real av-sync timing engine).
  - **Diagnose lane** — loading / unauthorized / error / ready-form / result.
- **Route Map panel** (`data-yemaya-voice-video-communication-route-map`): `<h2>`
  "Route Map" with five entries.
- **Quick-action panel**: two `quickAction` links.

## States

- [ ] **Loading** — `data-yemaya-vvc-loading` ("Loading diagnostics…").
- [ ] **Unauthorized** — 401/403 → `data-yemaya-vvc-unauthorized` with reason
      "Yemaya workspace scope required to view voice/video communication.".
- [ ] **Error** — non-OK / malformed catalog → `data-yemaya-vvc-error`.
- [ ] **Ready-form** — catalog (`metrics`) loaded; the diagnose form renders.
- [ ] **Result** — 200 → `data-yemaya-vvc-result` with `data-yemaya-vvc-drift`,
      `data-yemaya-vvc-frame`, `data-yemaya-vvc-db`, `data-yemaya-vvc-buffer`.
- [ ] **Validation error** — non-finite timing fields or non-numeric frame times,
      or a non-200 POST → `data-yemaya-vvc-diagnose-error`.

## Interactions

### Diagnose lane

`<form data-yemaya-vvc-diagnose-form>` — each `<input data-yemaya-vvc-field={key}>`
(aria-label = field label):

- [ ] **Audio time (s)** — `audioTime`.
- [ ] **Video time (s)** — `videoTime`.
- [ ] **Sample rate (Hz)** — `sampleRate`.
- [ ] **Samples / frame** — `samplesPerFrame`.
- [ ] **Amplitude (0–1)** — `amplitude`.
- [ ] **Buffered frame presentation times** — `frames` (comma/space separated).
- [ ] **"Run diagnostics"** submit (`data-yemaya-vvc-diagnose-submit`) — POSTs `{
      audioTime, videoTime, sampleRate, samplesPerFrame, amplitude, frames? }`.

### Route map

`data-yemaya-voice-video-communication-route-map` — five entries:

- [ ] `/studio/yemaya/voice-video-communication`
- [ ] `/studio/yemaya/voice-video-communication/scenes/[sceneId]`
- [ ] `/studio/yemaya/voice-video-communication/exports/[exportId]`
- [ ] `/studio/yemaya/voice-video-communication/revisions/[revisionId]`
- [ ] `/studio/yemaya/voice-video-communication/governance/[policyId]`

### Quick actions

- [ ] **"Open Yemaya Cursor and Selection Sharing workspace"** →
      `/studio/yemaya/cursor-and-selection-sharing`.
- [ ] **"Back to Studio workspace index"** → `/studio`.

## Data & contracts

- **Reads**: `GET /v1/admin/yemaya/voice-video-communication` (catalog; `metrics`)
  on mount with `buildBffAuthHeaders()`, `cache: 'no-store'`.
- **Writes**: `POST /v1/admin/yemaya/voice-video-communication/diagnose` → `{
  diagnostics: { driftSeconds, frameDurationSeconds, amplitudeDb,
  bufferDurationSeconds } }`.
- **Realtime**: None.
- **Caching**: client `fetch` on mount, no-store; aborted on unmount.
- **Auth/role check**: admin-scoped, fail-closed; route additionally signed-in +
  studio via the proxy gate.

## Open questions / known gaps

- [ ] The lane diagnoses from manually-entered timing values; confirm whether a
      live-session capture path (reading real av-sync telemetry) is planned.
- [ ] Route-map children (`scenes`/`exports`/`revisions`/`governance`) are a
      sitemap contract; confirm which dynamic pages exist.
