Ch.16 — 360-lane phi-distance grid

Master: trios#380 · Part: IV — EMPIRICAL
Scope: software-only (Rust/Zig), no hardware/FPGA/KOSCHEI
Words: 700 · Priority: 🔴 P0 · Owner: bench-agent

🎯 Scope (FROZEN, v2.1 SOFTWARE-ONLY)

360-lane benchmark grid: 12 formats × 6 architectures × 5 seeds (subset of all sanctioned). Heatmap visualization, per-cell mean/SD, win-loss against bf16 baseline. Live data via PR-6 dashboard.

🔑 Key claims / formulas
