{"line": 50954, "last_message": "Files tab rows now highlight on hover like Activity rows, and clicking one opens that file's changes since the last commit (to-do 709). This is released as 2.84.20, tagged and pushed through the boot guard. The full suite (134) and all checks pass, and I checked it in the viewer.\n\n- **Clicking a row** opens the file's changes. A new file shows in full as added, and a deleted file shows what was removed. A \"Whole file\" link switches to the file itself, and \"Changes\" switches back.\n- **One diff style:** the commit page and the file page now draw diffs with the same shared component.\n- **Hover:** I didn't hover a row in the browser to watch the highlight. It uses the same style as the Activity rows.\n\nWhile testing, the viewer threw an error on a fresh page load: it reads a list's filters before the types have arrived. That error isn't from this change, so I filed it as to-do 766. I also updated the journal's note on spotting subagents (fact 14) to say they're now recognised by the `agent_id` in the hook input."}
