"""v573 -- PRIME.PAIRBAND.01: the dominance behind the one-mode reduction is LONG-RANGE -- every near band of the pair kernel drags negative, the whole positive excess of det S lives beyond 16 lag cells with a stable net, and the scramble control shows the real placement holds det S ~50x BELOW random while organising its far-band coherence. PROVENANCE. v570 reduced the v569 spectator separation to the dominance det S >> det B and killed the cheap two-atom witness. This module types WHERE the dominance lives, on the declared surface (v563 T170 frame-A scan, read-only; a DECLARED subset for the O(n^2) kernel dissection: every 12th window with <= 16000 atoms, plus the h = 540 reference). Audited by the discovery probe (pair_band_structure_probe.py, 10/10, verdict LONG-RANGE). [E] 1. the band decomposition is exact per window (diagonal + six bands = det S, Cauchy-Binet). [MEASURED] 2. EVERY near band (< 16 lag cells) and the diagonal are NEGATIVE on every selected window: the near-diagonal region drags -- any near-diagonal mass budget aims at the WRONG SIGN. [MEASURED] 3. the far band (>= 16 cells) carries the WHOLE excess: net far/det S in [1.55, 1.91] stable, while the gross positive far mass grows 4.1 -> 13.0 x det S: the dominance is LONG-RANGE COHERENCE, not local mass. [MEASURED] 3b. THE SHARPER ANATOMY: the excess is SCALE-LOCKED (pairs >= h/2 apart carry a large growing positive net while the bands 16..256 stay negative) and WEIGHT-CONCENTRATED -- the top-10%-weight pairs alone net 0.85..1.00 x det S on every selected window: essentially det S itself, everything below the top weight decile cancels to ~0; and the lag-grid PHASE plays no role (the signed far mass is flat across the declared phase bins, spread shrinking with h): the certificate target is HEAVY-PAIR coherence at WINDOW-SCALE separation. [MEASURED] 3c. the per-atom share of det S OSCILLATES across the window with a fixed sign pattern (positive at x ~ 0.3 and 0.8, negative just past the midpoint), amplitudes growing with h while the net stays 1 -- a standing-wave-like anatomy, no mechanism claim. [E] 4. MUST-BREAK, in both directions: the position scramble EXPLODES det S by ~x49 (the real placement suppresses det S ~50x below random) and collapses the far-band share below 1 -- the coherence is arithmetic placement. NAMED LIMITS AS LOAD-BEARING CONTENT: declared surface and declared subset only; MEASURED quantities carry the surface ladder (the v562 anti-promotion applies); the consequence is a TYPING of the open v570 dominance question (its certificate must control >= 16-cell coherence; Chebyshev near-diagonal budgets cannot reach it) -- no bound, no rate, NO RH statement; Paper-II Problem 7.1 untouched. Fences: Cauchy-Binet CLASSICAL; the v563 fence chain unchanged. Python-only, counted per GATE.WOLFRAM.02. Discovery: experiments/tfpt-discovery/pair_band_structure_probe.py (2026-07-31, 10/10, LONG-RANGE).
