Why this run exists

PR #1514 · SP8192 + Muon 0.97 + Legal Score-First TTT

The combined Muon 0.97 and causal token n-gram tilt variant improves the direct PR #1413 predecessor; the score delta is not attributed to either change alone.

Method before metrics.

On PR #1514: SP8192 with Muon 0.97 and legal score-first TTT; 3-seed sweep beats #1493 (p=0.020) Declared changes include: Score-first TTT only — every sliding-window chunk is scored under inferencemode() before any gradient update. No chunk is trained on before scoring. No SLOT, no pre-quant TTT on val data, no n-gram cache, no ETLB. [x] Score-first TTT ordering verified

Hypothesis
H-PG-1514 · The combined Muon 0.97 and causal token n-gram tilt variant improves the direct PR #1413 predecessor; the score delta is not attributed to either change alone.

The comparison contract.

A reproduction matches this protocol. A fork changes it and declares the deviation.
