Compare a constant galactic acceleration scale with a scale proportional to H(z), using a reproducible phenomenological model and published MUSE-DARK fitted curves. Preserve the distinction between those summaries and a new fit to galaxy measurements.

• Add an empirical RAR forward model, conditional baryonic Tully–Fisher predictions, deterministic artifacts and a figure.
• Preserve source locations, confidence conventions, same-sample dependence and retrieval limits. Credit the existing H-tracking reanalysis.
• Define the remaining full-data inference protocol and connect the study to fractals, physics0 and astr0.
• Record known pair production and the separate requirements for a cosmological-collision conjecture. No connection to the acceleration law is derived.

Validation: 13 local tests and both generated-artifact checks passed. Independent source/code and companion-document reviews found no substantive issues. The hosted Python 3.12 and 3.14 workflow also passed.

Seven existing generators passed. The unchanged Wave 4 certificate lacks its required canonical checksum and fails its existing verifier. The validation record identifies the baseline and does not claim the whole repository passes.

No new raw-data likelihood, fitted exponent, discovery significance or human scientific review is claimed. The selected MUSE radial data and covariance remain prerequisites for the next empirical step.

Companion drafts: fractals, physics0, astr0.

Follow-up: the current value assessment adds exact calibration symmetries, synthetic controls and an updated data-access audit. This PR retains its historical model and published-summary comparison; no individual-galaxy fit is added.
