A room_send action, approval copy, a rooms status section and join-on-publish all ship, with no flag or env var that reaches them.
What
A complete broadcast-channel feature for artifacts ships in the code, including a room_send action, its approval copy, validation, result rendering, a topic/data argument pair, a rooms section in artifact status and join-on-publish machinery. None of it is reachable, and no flag or environment variable can turn it on.
Details
- Every entry point goes through a module handle that is set to null and never assigned anywhere in the bundle, so the enabled check is always false,
topicnever enters the frozen schema,statusnever emits aroomssection, and the accessor for the implementation throws. - Same null-placeholder pattern used for the live-edit module. Turning it on requires a different build.
Evidence
artifact rooms are not compiled into this build
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
