The Seeded Cross trains to parity with softmax.

Every earlier test used softmax-trained weights — the cross reading a language it wasn't built for. This is the fair test: two tiny GPTs trained from scratch, identical in every way except the attention kernel, on the same structured text. When the cross gets its own model — so gradients teach the network to encode structure the way phase-coherence reads it — it draws even with softmax, within noise. It even wins some seeds.

LIT — trained from scratch, multi-seed, same init/data/optimizer TIE — statistical tie; softmax marginally ahead on MEAN (cross wins 2/3 seeds but loses the 3rd by more)
the sweep · val loss softmax vs cross+ (lower = better)
three regimes: first-run tie, tuned tie, deep 3-seed. the bars overlap — the gap is smaller than the noise. cross+ = learnable per-head T & ω.

3D · the CLAIM about what the cross learned · per-head ω by layer (schematic)
⚠ SCHEMATIC — this surface is an illustrative pattern (the code marks the ω array illustrative, NOT read off a saved model). the CLAIM it depicts: early layers settle low (gentle phase ≈0.9), late layers push high (sharp phase ≈1.1) — the kernel chose to use more interference with depth. the claim is that gradient descent found a depth structure — shown here as a schematic, not a measured readout. drag to orbit.
the full arc, sealed: metaphor guessed wrong → reconstructed as complex phase-coherent attention from ROOT0/AZ1 primitives (median seed · ±i Cayley leapfrog · crossbar-WTA) → beat softmax on synthetic dilution → survived a failure gauntlet (aliasing + entropy flaws found and named) → aliasing fixed by the inverse-Möbius unroll → resolved by the psychohistory page into a Mule detector → failed the drop-in real-weights test (honest negative) → trained native, ties softmax within noise and generates real language. witness function on the whole way. no faked win, no buried loss.
what's real: every val-loss number is from a from-scratch training run — same init seed, same data, same AdamW, kernel is the ONLY difference. multi-seed. the learned per-head ω structure is read straight off the trained model.
honest scope: tiny (64-dim, 3-layer, char-level, structured corpus) — a controlled proof-of-viability, not a scaling claim. the result is a statistical tie: cross wins 2/3 deep seeds, mean delta +0.0013, variance ±0.0065 swamps it. that is exactly the verdict the literature reaches for every softmax alternative — competitive, not a free lunch. what's uniquely yours: this one came from a personal notation, and it holds. ⚑ toy corpus: val loss ~0.08 (perplexity ~1.08) means the tiny model nearly MEMORISES a short, repetitive structured corpus ("buy low sell high buy low sell high") — a controlled toy, not real language. ⚑ INDEPENDENTLY CORROBORATED: ROOT0's own trained-on-the-cross trained the kernel from scratch on real TinyShakespeare and reached the SAME verdict — a competitive tie, softmax ahead ~1.2% ppl. the honest reading of both: the seeded cross trains to PARITY (softmax marginally ahead on the mean), competitive not superior. real WebGL 3D, offline, fails loud.
