Summary

  • Browser publishers mint private try broadcasts through the API added in moq-dev/moq.pro#1376. Watch links contain no publish credential; watch clients mint an exact-broadcast token when needed.
  • Remove implicit project selection. Legacy query links and the moq.dev watch page require both project and name; explicit demo, anon, custom relays, and supplied tokens remain supported.
  • Configure API, relay, and hosted-player URLs together per environment. Replace public-sandbox embed snippets with hosted embeds that obtain credentials at runtime, and document the explicit public terminal sandbox.

Validation

just fix, just check, just test (22 passing), and all three staging builds passed. Browser checks confirm missing-project links show usage, both publishers mint private broadcasts, and the copy/share links contain no publish token. A synthetic-video test against the matching local API/relay decoded media with a separately minted watch token and confirmed anonymous relay/dashboard refusal.

Rollout

Depends on moq-dev/moq.pro#1376. Deploy the API and seed try in the matching environment before deploying these clients. Credentials last one hour. No deployment performed by this PR.

Walkthrough

The clients now use configured API, publish, and watch URLs. Bare publish-site visits mint private try broadcasts through the API. Watch clients obtain try credentials before mounting broadcasts. Routing requires explicit project and broadcast values. Publish and watch embeds use configured site URLs. Random broadcast-name generation was removed. Documentation and setup instructions now describe private try broadcasts and explicit links.

Merge Risk: 🟠 High · up to 6a946

Browser users cannot create or view private try broadcasts when the API blocks credential requests, and one demo instruction still opens an invalid player URL. The credential-flow issue should be fixed before merge.

Add the required broadcast parameters to this player link.

The bare /watch URL no longer identifies a broadcast. It opens the Watch page without project and name, then enters its error state. Link to a specific stream such as /watch?project=demo&name=bbb.hang, or state that callers must supply both parameters.

Add Access-Control-Allow-Origin for the configured client origins. request sends JSON POST requests, which require a CORS preflight. The /try/token and /try/watch responses allow POST and Content-Type, but omit Access-Control-Allow-Origin. Browsers block both credential flows before token validation.
