🟡 Minor · Reset inactive file sources to undefined. · file.ts:136
js/publish/src/source/file.ts:136
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winReset inactive file sources to
undefined.Both
effect.setcalls retain{}as their cleanup value. When decoding stops, the signal therefore becomes{}instead ofundefined.Use
undefinedas the cleanup value in both paths. This keepsFile.out.sourceconsistent with its new contract and lets consumers detect an inactive source.Proposed fix
- effect.set(this.#out.source, { video: { frames, frameRate: IMAGE_FRAME_RATE } }, {}); + effect.set(this.#out.source, { video: { frames, frameRate: IMAGE_FRAME_RATE } }, undefined); ... - effect.set(this.#out.source, source, {}); + effect.set(this.#out.source, source, undefined);Also applies to: 184-184

Problem
The JavaScript watch, publish, and room packages exposed inconsistent construction, state, and media-source shapes. Compatibility aliases silently translated removed names, room publishers did not receive the connection bandwidth estimate, and switching or clearing publish sources could leave stale source state observable.
Approach
Sync.reloadtoannounced, refuse removed latency/jitter setters, and make instant audio gating a decoder invariant.{ video?, audio? } | undefined, remove the duplicate element capture surface and audio encoder mute control, and expose source selection read-only.undefined.room.Localfrom a connection, feed its bandwidth estimate into all six encoders, and keep only the source, capture, and broadcast fields consumers use.Impact
This is intentionally breaking for
@moq/watch,@moq/publish, and@moq/room, and targetsmainfor the final pre-release pass.@moq/watch: decoder, renderer, emitter, and text renderer constructors now take one props object.Syncno longer accepts audio/video jitter inputs; decoders register their active jitter with it.reloadis nowannounced, and removed latency/jitter setters refuse writes. The caption renderer field is nowtextRenderer, andparseCatalogFormatis exported only from the element entry point.@moq/publish: every source signal returnsSource.Media | undefined, whereSource.Mediais{ video?: Video.Source, audio?: Audio.Source }.Audio.Encoder.mutedis removed in favor of its volume control.Broadcast.maxAgeusesTime.Milli. The element no longer exposes a duplicate top-level capture field, and its source collection is read-only. Changing or clearing a selection now clears inactive video, audio, and file holders as well as captured media.@moq/room:Localtakes aConnectionrather than exposing an origin getter, acceptsGetterInitcontrols, hides internal captures and encoders, and sharesconnection.bandwidthacross all six encoders.Repository demos, tests, and documentation are migrated. Out-of-repository consumers, including moq.pro, need the same API migration.

Follow-ups
None required for this release. The automated documentation-coverage warning was reviewed; the newly exposed public symbols are documented, while the reported gaps are constructors or private implementation functions.
