Five display rules: 6.2.2.1 sent text and text from each source shown with the source indicated and differentiated (a unique label such as 'Speaker 2' suffices); 6.2.2.2 where voice speaker indication exists, all active communicators shown including RTT users; 6.2.2.3 a real-time on-screen indicator of remote audio activity; 6.2.2.4 text from each source, including local, presented as blocks ordered by when each block ends (sentence-ending punctuation followed by a space, a line separator, or 5 seconds without new characters), with editing moving the block's end time to the last edit; 6.2.2.5 the whole RTT content reviewable during the call and, where recorded, afterwards.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
