Sealed prediction: extended SPARC + MeerKAT/SKA HI rotation curves

Sealed prediction file (plaintext) for Extended SPARC galactic rotation curves. Embargoed until 2028-12-01, on which date the file is automatically released by Zenodo. a_0 = 1.04e-10 m/s^2 exactly; BTFR slope = 4.0 Cross-references the encrypted (AES-256) version with public SHA-256 hash on the master record. Both layers — embargo and encryption — prevent post-hoc adjustment of the prediction. Theoretical derivation chain: Pub1 (Steiger 2026), 10.5281/zenodo.18924129.
