PNJL raw rho-mu curves for the C2 phase-grid coverage

This dataset contains the complete raw rho-mu curves generated for every exact (xi, T_MeV) coordinate present in the C2 phase_grid_convergence artifact with axis=rho. The producer is independent_oracle at the highest-precision raw-only settings. Scope and schema: 10,458 curves over 93 xi values; each curve is a byte-preserved UTF-8 CSV with 28 source columns and the complete rho=0:0.003125:4 set, for 1,281 rho points. rho is reported in rho/rho0 with rho0=0.16 fm^-3. T and chemical potentials are in MeV; pressure and energy are in fm^-4; entropy and quark densities are in fm^-3. Solver status fields are retained.

The archive artifact SHA-256 is 467be7fb1075d1a5f0de3dd0d8afe29d9206a156c0ca7135a1e50967a4f18ccc. Validation: status full_domain_verified. The archive includes archive and source manifests, SHA-256 sidecars, a full curve index, and a representative index that references the full set. No C0/C1/C2 rerun, Maxwell, CEP or boundary analysis, hybrid policy, reference promotion, or transport postprocessing was performed for this dataset.
