measure-chat-flicker
Measure whether the chat jumps while a turn runs by sampling the Working line's position over CDP and counting upward moves. Use when changing step rows, live status lines, folding, or anything that can shrink content during a run.

Measure chat flicker
Content growing below is normal. Content shrinking during a run (a live line removed, a group closing) moves everything up, and that reads as flicker. This counts those upward moves.

node $M report # { upwardJumps, downwardMoves, samples }Note: repro.mjs opens its own new session, so arm after it if you need the arm to survive the navigation, or run send directly.
Reading the result
upwardJumpsduring the run should be 0. One at the very start (the first step replacing "Starting…") is acceptable.- Reference: before the live step moved onto the group's own line, five sequential commands gave 6 upward jumps of about 22px in 27s; after, 1.
- Run the same prompt before and after a change and compare. Keep the window size fixed between runs.
