Setters for the coefficients

Set saturation properties from p ! This function sets the saturation properties for the given pressure p. The computed values are written to the E

Set the internal variable T without a flash call (expert use only!)

Set the coefficients in the EOS

Supercritical-target solver: anchor on the dome-free isotherm at T = Tmax with a density chosen so the anchor entropy already equals s_t, then run the

Find T such that h(T, p) = h_target via bracketed TOMS748 iteration on the source backend's forward h. Bracketed (vs Newton) so we stay robust across

Entropy analog of solve_T_from_h_toms748. s(T) at fixed p is strictly increasing (ds/dT|p = cp/T > 0), so the bracket is at least as robust as the en

The (a1, a2) alpha0 offset pair that was active when build() was called, or nullopt if build() has not completed successfully.

level may actually range from [0,10] (10 is a "hidden" max level, where we want a bit more compression and it's fine if throughput to fall off a cliff

Lowercase 16-char hex representation of a 64-bit hash. No "0x" prefix. Suitable as a filename-safe cache-key fragment.

Out-of-line definition of the TOMS 748 bracketing rootfinder declared in the installed header. Keeping the boost dependency here (rather than in the
