- Tests 1 to 5000 fields to find crossover point - Confirms stack copying is O(n) at 0.16 ns/field - Confirms Dict mutation is O(1) at 7 ns constant - Crossover at 100 fields (800 bytes) for updates - Typical FEM elements (20-60 fields) well below crossover - Immutable wins for access and iteration at ALL sizes - Generates 5 publication-quality plots - Exports JSON + CSV with system specs - System: Intel Xeon Gold 6326, 32 cores, 503 GB RAM
