  # Changelog
  
++## 0.158.0 — 2026-11-12
++
++- **`openvibe-sdk/views`: one view API for every content kind** (Contracts `media.view-request@1`, the `media.viewed`
++  and `media.engaged` events).
++  - `createViewsClient(client).record(event | [events])` posts a preview, watch or live heartbeat for
++    `ref: { service, kind, id }` to Media's `POST /api/v1/views`, up to 20 at once. `seconds` is cumulative for the
++    session and item, so a retry does not count twice; a signed-out viewer keeps an opaque session id.
++  - `.counts(ref)` reads one item's `{ views, engaged, previews, preview_share, peak_concurrent }` from
++    `GET /api/v1/views/counts`. Media never stores an IP address or a user agent with a view, and a preview counts
++    from 1 second.

    `handBack(run, desk, note)` and `replay(run)` → the steps with the still each saw. They call the same-named routes
    under the client's service (`/api/v1/runs/:id/desks/...`), so a page and a script make the same calls. No tag: the
    main session releases this after the sites' stage lands.

  It has no runtime dependencies. It needs Node ≥ 20, or any browser with `fetch`, Web Crypto and `TextDecoder`. There is no build step. The package is CommonJS with ESM entry points (`import` works). Each subpath has its own `.d.ts`. For a page with no bundler, `browser/openvibe-sdk.mjs` is one self-contained ES module of the browser-safe subpaths (see [Browser without a bundler](#browser-without-a-bundler)). It does not depend on `openvibe-contracts` at runtime: it copies the contract types it uses (from the temporary Contracts sharing branch, a devDependency the tests check them against).

++ * POST /api/v1/views is public and CORS *, dedupes one view per person or anonymous session per item per 30 minutes,
++ * counts a preview from 1 second and engagement at 30 seconds or a third of the length (60 seconds of a live stream),
++ * and never stores an IP address or a user agent. `seconds` is cumulative for the session and item: a retry sends the
++ * same number, playback sends a larger one, and neither counts the item twice.
++ *
++ * A signed-in viewer sends their Network token on the client and no session; a signed-out viewer keeps an opaque
++ * `session` id of their own. The write is not retried for you: a retry is safe (same session, same item), but this
