Experimental work: SPLIT-HEAD CRAWLER SCALE GATE (x16): architecture family detected in measured rows; exact flags are preserved in the row details. SLOT-TUNED TRANSFORMER BODY (x5): architecture family detected in measured rows; exact flags are preserved in the row details. CRAWLER-SAFE TRAIN/EVAL SURFACE (x3): Crawler-safe training/eval surface around a widened shared-crawler stack with final int6 and int8 checks. Specs: model_dim=512; vocab_size=1024; num_heads=8; num_kv_heads=4; BigramHash; XSA.
Neural work: SLOT-TUNED TRANSFORMER BODY (x2): architecture family detected in measured rows; exact flags are preserved in the row details.
Day 016 measured 28 architecture/test rows against VAL_BPB, with 22 valid rows and 2 TTT leakage readings excluded. Techniques to copy/reference: BigramHash; XSA; RoPE; crawler loop rope scales; instruction bottleneck; int6 roundtrip; int6 sliding-window eval; int8 zlib roundtrip.
No new personal best. Best valid of the day = 1.1035 (Add Slot Machine submission — 1.1035 BPB, 15.5MB); best-before-today = 1.0672 still stands. 4 crash-class outliers (3.39, 3.34) excluded.
