Chen gives the chase a higher target

Yi-Chia Chen @ Fields Model closes the Late edition on 75.56, ahead of Tufa Labs on 68.91. The observed score event took Chen from 71.48 to 75.56 overnight; the lead is now nearly seven points. Team Turducken remains third on 56.02. The leading name has held, but the score the challengers must catch has moved higher.

A new arrival inside the gold line

insuperabilehart reaches thirteenth on 39.79, up eleven places against the previous evening comparison and gaining 2.40 points. The wire reported a twelve-place rise against its earlier rolling window; those are different comparison boundaries. With the provisional gold score at 38.22, this is a move across the medal threshold, rather than simply a climb within the chasing pack. The ARChitects holds 38.85 but slips from sixteenth to seventeenth, showing how an unchanged score can lose ground.

The wider field keeps moving

The last dance remains fourth, mtg fifth and NVARC3 sixth. Below them, the wire recorded bil022 reaching 35.26 after a jump from 3,486th to 55th in its observed window, and Mehrdad_LU reaching 35.12 after moving from 367th to 58th. Its pensukesan dispatch recorded a rise to 37.22 and twenty-seventh. These are dated wire observations, not additional gains after those reports or a claim about each team’s closing rank.

The fairness question remains in the saved reporting

The Digest’s October 27 investigation records Kaggle’s acknowledgment of broader run problems and earlier staff confirmation that some rescores had begun. A saved public discussion read later that morning records CPMP asking whether an extension is being discussed, while Grigoriy Zatravkin argues that reruns cannot restore lost opportunities to learn from scores. These are competitor requests, not an organizer decision. Pathik Patel’s saved startup-workaround discussion also distinguishes avoiding a zero from recovering gameplay time lost to loading. The edition cannot establish which individual scores were affected.

Kaggle admits run problems. Who gives teams their lost week back? · Ravi Ramakrishnan — Scoring 0 possibly due to dataset loading issues · Pathik Patel — Healthy runs scoring 0.00 this week? It's the server-startup deadline (one-line fix)

What this edition can establish

The board evidence is fresh to this edition’s fixed cutoff. Social and discussion research was not refreshed for the Late edition; the community reporting above retains its saved October 27 check dates. Public medal bands remain provisional, and missing historical comparisons remain unknown.
