/**
 * time/resolveRecord — what the resolver writes down: the candidate and
 * choice shapes, the app's policy (read at `.time()`), and the checks the
 * checkpoint door runs on a filed reading.
 *
 * Pattern: the record half of `resolve.ts`, split from the resolver so the
 *          SYNCHRONOUS doors — `.time({ policy })` (`clock.ts` ·
 *          `readTimeOptions`) and `validateCheckpoint` (`rows.ts` ·
 *          `timeRowIsWellFormed`) — reach the shapes and their checks without
 *          the resolver, which only an armed seed loads (`agent/stages/
 *          timeLayer.ts`, through `import()`: the optional-family law of
 *          docs-next's site budget). `resolve.ts` re-exports everything here.
 * Role:    L0 leaf (the time layer). Imports `range.ts` and `zone.ts`
 *          (the window check) only.
 * Emits:   N/A.
 *
 * @example
 * ```ts
 * readPolicy({ dateOrder: 'DMY' }); // { dateOrder: 'DMY', year: 'ask' }
 * readPolicy({ abbreviations: { PST: { zone: 'America/Los_Angeles', offset: '-08:00' } } });
 * // { dateOrder: 'ask', year: 'ask', abbreviations: { PST: { zone: 'America/Los_Angeles', offset: '-08:00' } } }
 * candidateIsWellFormed({ kind: 'range', range: { from: 'x', to: 'y' } }); // false
 * ```
