Locate propagation costs before changing the method

The complete prediction study has 16 time-limit failures. Profile two new, shortened generated-input calculations to locate costs before optimizing. This is diagnostic work, not a retry of any failed region.

Use the zero-field globe source under fixed-zero and profiled removal, each with its first 128 original packets and a query at 0.32 seconds. Construct new source references and physical-domain proofs for the shortened inputs; do not transfer full-history training certificates to changed sources. Keep sector 4, the original calibration caps, both source phases and all 27 derivative columns.

Finite allowance

Freeze source, inputs, compiler and environment. Preserve profiler output even if a bound does not finish. Report costs separately from qualification: profiler overhead and shortened histories do not establish full-history runtime, narrower prediction intervals or observational uncertainty. The completed comparison and all its failures stay unchanged.
