Peritheos 0.16.1

Added

• Integrate the Fe2SiO4 ringwoodite endmember as a derived Finger (1979) static ambient-cell reconstruction, with source structure, all three observations, explicit uncertainty scope and 296.15 K / 0–4 GPa limits. Keep the unresolved 2011 thermal candidate staged.
• Replay eight conditional Sakai (2025) calibration stages from measured paired volumes, expose six additional source tables through the dataset API, and provide source/refit curves, residuals and conditional errors in light and dark themes. Preserve the published coefficients and full-network limitations.
• Archive actual EosFit GUI fits on the confirmed Morard FeS inputs, including a cold-then-hot workflow, saved covariance and screenshots. The tested GUI and console agree closely; preserve the separate residual-envelope discrepancy.

Changed

• Accept the unchanged Morard (2026) FeS source EOS in the executable catalog on staged parameter agreement within reported uncertainties. Retain the similar reconstruction label and the unreproduced ±3 GPa envelope as an informational qualification; exact author workflow and formal uncertainty parity remain unverified.

Fixed

• Keep reconstruction freshness checks portable across equivalent fixed-parameter name ordering and allowed numerical replay roundoff, without changing source values, covariance-array order or retained report precision.
