DOILY.HODGE.FACTOR.01
v880 (part 3) -- the doily IS the multiplication table Lambda^2 E x Lambda^2 E -> Lambda^4 E of the five-slot carrier: via the v845 parity lift the three iota-supports of every doily line partition {1..5} as {i} u {j,k} u {l,m}; b_jk ^ b_lm = +-f_i EXACT (integer exterior algebra); the map line -> (i; {j,k},{l,m}) is a BIJECTION onto all 5 x 3 = 15 configurations (three perfect matchings per carrier slot); CONVERSE: the wedge is nonzero EXACTLY on doily lines (external lines: all pairwise products vanish; secants carry <= 1 pair point). Probe S3.
Recorded status: Exact identity-grade theorem [Identity]: the incidence geometry IS the Clifford multiplication; no marker move
