/**
 * Assemble the model surfaces from a resolved constants context + fitted
 * coefficients. Internal: `createModel` in index.js composes this with the
 * §2d context validation and counterfactual hashing — call that, not this.
 *
 * @param {Readonly<Record<string, any>>} C  the frozen constants context
 * @param {Readonly<Record<string, any>>} F  the fitted coefficients
 * @param {import('./model/context.js').Laws} [laws]  research overrides for Earth's orbit laws
 *   (model/context.js); default {} = the shipped laws, bit-identical to before this parameter existed
 * @param {any} [secularSeriesArtifact]  the governed N-body secular series (the API/Node path; the
 *   npm package alone has no 8 MB series)
 * @param {import('./model/context.js').Options} [options]  `giaEllipticityOfDate: false` = the orbital
 *   forcing alone (model/context.js); default true = the shipped physics, bit-identical to before
 * @returns the assembled surfaces (epoch, earth, lengths, cardinal, moon, …) — type inferred so ReturnType stays precise
