/**
 * Minimal read-only wrapper over a `Vault`. Used as `ctx.vault` inside
 * guard / derivation callbacks so they can fetch related records without
 * acquiring any write capability.
 *
 * The `layer` tags every `get`/`list` read with the resolution layer it
 * belongs to. A guard-seeded facade reads at `'guard'`, a
 * derivation-seeded one at `'derivation'`, so i18nText / dictKey fields
 * resolve under that layer's `onMissing` policy instead of the `'read'`
 * policy — e.g. a guard read can `substitute` a missing locale (lenient
 * default) while the same field `throw`s on an ordinary app read.
 *
 * `query()` is left untagged: the query/aggregate pipeline reads raw
 * `{locale}` maps (no resolution call site), so a layer tag there would be
 * inert. Routing `mv`/`join` resolution through the pipeline is tracked
 * separately.
