/**
 * Builtin op input projection + `x-mantle-bind` stamping (POC ADR-0014).
 *
 * Two transforms applied to `Procedure.input` before it lands in
 * `EntryRepository`:
 *
 *   1. **Projection**: copy only the keys declared on the target
 *      Schema's `spec.schema.properties`. Side-channel fields (CAPTCHA
 *      tokens, hCaptcha challenges, etc.) declared in the Procedure's
 *      input but not in the Schema's properties are silently dropped
 *      from the row. They remain available as the input to matching
 *      synchronous `before_*` lifecycle hooks only.
 *
 *   2. **Stamping**: any Schema property carrying `x-mantle-bind: <value>`
 *      gets its value computed at write time:
 *        - `ctx.user` → `ctx.user?.id ?? null`
 *        - `ctx.staff` → `ctx.staff?.id ?? null`
 *        - `now` → `clockNow` (caller-supplied; lets the use case
 *          share its `Clock` so created/updated stamps line up)
 *
 * Stamping overrides whatever the caller passed for that key —
 * declarative server-stamping is the contract.
 *
 * Pure stateless service — no I/O. Lives in `domain/service/`.
