Master's "fix(acp): align prompt and workspace contracts" changed the editor-
facing transcript — `user/message` → `user_message_chunk` is now emitted during
session/load replay ONLY, not live streaming, so a live prompt no longer echoes
the user message back. The snapshot tier caught this (6 goldens shifted); this
re-records the four recorded scenarios against the API and re-accepts the two
authored goldens so they reflect the merged behavior. Full suite green and
deterministic; this is the tier working as designed.
