Evidence and limits
Finding: Participants coordinate by establishing enough mutual understanding for the current purpose, with grounding costs shaped by the communication medium.
Impact: Strengthen explicit grounding checks at handoff boundaries. Reject transcript volume as proof of common ground.
Boundary: Human communication theory does not validate an AI protocol. Next: which observable acknowledgement and repair signals show sufficient grounding without adding excessive process?
Flags: human communication; medium and task transfer
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
