Scaling Evidence for Sheaf Diagnostics
How do the structural measures scale in the frozen experimental regime?
Key result
The demonstrated finding is baseline collapse: depth-3 testing 0.28 → 0.04 and best conventional 0.83 → 0.52 as size grows 5 → 50. The sheaf line holds R² > 0.96 but is structurally favored (see status); cohomological invariants alone score near zero (dim H¹ 0.093, coherence fee 0.000).
The reported regime change is limited to the disclosed protocol and baselines.
Abstract
Documents the regime change where conventional testing breaks down as composition size grows. Six convention dimensions grounded in real standards.
