endpoint-hessians-replication: Replication package for "Float32 Can Materially Distort Finite Activation-Patching Interactions"

Complete replication package (version 3.24.0, 862 files) for "Float32 Can Materially Distort Finite Activation-Patching Interactions: Empirical Precision Floors and Displacement-Dependent Endpoint-Curvature Error." Contains: all matched float32/float64 sweep records for GPT-2-medium and Pythia-410M plus per-scale float32 replications (Pythia-160M/1.4B); ten trained synthetic transformer checkpoints and the complete gate-topology study data; the softmax-dtype patch provenance with bitwise identity tests; cost-fixture raw timing repetitions; the deterministic 390-check verification program (code/verify_headline_numbers.py) that regenerates or quote-locks every headline number; figure-generation scripts for all seven publication figures; the author's pre-analysis specification record (data/prereg_record/, amendment packages 4–12 with verifying per-file hashes; assembled post-analysis, not independently timestamped preregistration); per-directory SHA-256 manifests; and the LaTeX sources and compiled PDFs of the manuscript and supplement. Run python code/finalize_release.py --check (with OMP/MKL/OPENBLAS_NUM_THREADS=1) to reproduce the full verification gate. See README.md for the reproducibility map.
