/** Does `doc` pass its gate for `subject`?

 *  - No gate (field absent) ⇒ `true`: always eligible (the common case).
 *  - A gate present ⇒ the matcher engine's verdict. An empty `gate: {}` is inert
 *    and returns `false` (never matches) per design §4 — so an author cannot
 *    write an always-eligible-via-empty-predicate doc.
 *
 *  Eligibility only. A failing gate excludes the doc from BOTH automatic hooks
 *  for this node; it remains findable by `crtr memory find` (search ignores
 *  gate + rung). */
