SPARC galaxy rotation-curve data is absent
Pre-Physical Selection & Emergent Reality — Ch. 13, 21
Original criticism
The dark-matter account's most direct observational test — comparison against real SPARC rotation-curve data — is not run anywhere in the corpus's own validation suite.
Response & evidence
Confirmed absent, not worked around with a substitute. See /validation/sparc for the full detail.
