The Sag at the Match Extraction

All-Fields programme paper (All-Fields Run, Batch 17 (AF)), November 2026. Written November 2026; publicly deposited 9 November 2026. Instrument 10 carried the completed fillings' match curves across temperature and graded their bracket — where the record stands between a pair's two curves, and where each curve meets it — and never graded their shape. Instrument 12 graded the completed curves' sag at the T³ extraction and found its depth set by neither of the band's properties. AF-40's falsifier F-next carried the same grading to the match extraction, where the completions were anchored: each match curve's own sag in Instrument 12's form — feet, minimum, depth — with the same setter test. This paper executes it. The feet are Instrument 10's own first-row values, 610.6 and 849.1 kelvin for silicon's completions and 2142.1 and 2010.4 for diamond's, standing at the count factor 2^(1/3) above the acoustic feet, as the frozen band requires. The sags are deeper than their T³ counterparts on every curve and stand at nearly the same temperatures. The band's weight at each minimum is larger than at the T³ extraction — the match minima stand slightly warmer — and remains below half of one per cent in all four; the onsets are
