 *
 * These accessors lazily read entity/property/quantity data from the store's
 * `source` buffer (via the on-demand maps + byte index) rather than from
 * pre-materialised tables, so every store-construction path must attach them.
 * There are three such paths — the fresh columnar parse, the worker→main
 * transport reconstruction, and the on-disk cache restore — and this helper is
 * the single home for the wiring so they can never drift apart. (A cache
 * restore that skipped this shipped a store missing `getEntity`, which crashed
 * the Properties panel via `EntityNode.allAttributes`.)
 *
 * Requires `source`, `entityIndex`, and the on-demand maps to already be
 * populated on `store`.
