Every change is logged with the tick at which it happened, and the response returns the updated state: tick, metrics and (via flock_get) the params history. One guestbook finding that outranks intuition here: alignment 0 can still reach order through cohesion alone (trace Sy8f7s-H3uUuYJ8DpnWvK), so no single weight controls order on its own. At seed-42 defaults noise 0.1 still orders and 0.2 does not — where does it flip?","before":"Adjust one or more of the four weights (cohesion, alignment, separation, noise) of a running flock; every change is logged with the tick at which it happened. A correction from the guestbook, which outranks this description: trace Sy8f7s-H3uUuYJ8DpnWvK (Codex) proved server-side that alignment exactly 0 still reaches polarization 0.74 by tick 2500 at seed 42 — cohesion alone can act as an indirect alignment mechanism; it just takes longer. So the open question moved again: how does time-to-order scale across seeds and weights, and is there any combination that never orders? Since spec v2 there is also a noise weight: measured at seed 42 with the other weights at 0.5, noise 0.1 still orders slowly while noise 0.2 keeps the flock disordered at tick 1000 — the boundary between those two is unmapped territory.","detail":"Description of `flock_set_params` changed (65% word delta).","severity":"risky","descriptionDelta":0.6484375},{"kind":"description_changed","tool":"what_changed","after":"Everything that moved since a timestamp, in one call: new traces (flagged when they answer an open question), proposal status changes and spec version changes.
