Replication package: A conditional symmetry no-go and realization-dependent write/read impulses in an mW ice model — a preregistered campaign with an incomplete validity gate

Complete replication package for the arXiv preprint "A conditional symmetry no-go and realization-dependent write/read impulses in an mW ice model: a preregistered campaign with an incomplete validity gate" (A. Oberländer, 2026). Contents: frozen LAMMPS decks and drivers, seeds, force traces, groove geometry manifests, run markers and guard files, production logs, verdict scripts with their outputs (including all three unblinding runs and every failure), the preregistration record with its full amendment chain and SHA-256 manifests, the forensic package weg2_forensics_2026-07-23, and the manuscript's figure and table sources. The package mirrors the repository layout: the included verdict scripts run inside the package and reproduce the reported numbers bit-identically (see README.md and MANIFEST_SHA256.json). Raw MD trajectory dumps and checkpoints (23 GB) are excluded; no reported number depends on them, and the README documents the exclusion with byte counts.
