* It is the same argument `init`'s callback wrapping above rests on, and it lands the same
* way: the invariant is carried by COMPOSITION rather than by an instruction a caller gets
* to get wrong once. "Pass the package's `ng` to `initNg`" would be an ordering rule in
* prose, unenforceable and silent when missed - and it WAS missed, by both consumers in

/**
* The ORM family this package offers an application - the SDK's one-shot read and its
* subscription-free write, each WRAPPED at the same name and the same signature.
*
* -- Why wrapped, and never re-exported ------------------------------------
* `export { getObjects } from "@ng-org/orm"` would compile and would look like the most
* faithful thing available. It is the opposite: it hands the caller a path straight to
* the SDK that SHORT-CIRCUITS the emulation - the capability filter, and above all the
* shared-wallet identity boundary, which is the whole of what this package protects. One
* wallet hosts every identity here, so an unwrapped ORM read returns EVERY identity's
* data with nothing signalling it. Everything offered from this family is therefore
* wrapped; a symbol that cannot be wrapped meaningfully is not published at all.
*
* -- What each wrapper adds, and where the target does the same thing ------
* A READ is filtered on what comes back. `emulated-verifier/read-filter.ts` keeps only
* items whose document - their `@graph` - the current holder holds a cap for, which is
* the emulation of what the broker bounds at delivery, applied per document, exactly
* where `surface/use-shape.ts` and `surface/use-shape-query.ts` apply it.
*
* A WRITE is NOT filtered, and the asymmetry is upstream's rather than ours: a write is
* bounded by write capability - `verify_permission`, reachable only from `Commit::verify`,
* so it fires on commits and never on reads - and nothing is hidden from the writer. So
* `insertObject` takes a GUARD BEFORE the write (`emulated-verifier/reach.ts`), the same
* pair `docs.sparqlUpdate` takes, and never a filter over what it returns.
*
* -- The second door the guard needs, and where it is ----------------------
* These two wrappers guard the calls an application MAKES. They do not, and cannot, guard
* a mutation of a live signal object - `set.add(...)`, `set.delete(...)` on what a shape
* query handed back - because that write is made by the ORM itself, batched into
* `ng.graph_orm_update`. That door is guarded where every other `ng` call is, in
* `surface/ng-proxy.ts`, and `surface/lifecycle.ts` is what makes sure the ORM is holding
* the wrapped `ng` when it knocks on it.
*
* -- What is deliberately NOT published from this family -------------------
* `@ng-org/orm`'s entry also exports `RdfOrmSubscription`, `DiscreteOrmSubscription`,
* `ngSession`, and `getRaw` / `watch` / `effect` re-exported from
* `@ng-org/alien-deepsignals`. None of them is published here, and each for a reason a
* later reader can check rather than a preference:
*
* - `RdfOrmSubscription` - an application never holds a subscription: it hands the
* shape query to `configure` and reads `useShapeQuery`'s snapshot back (see the note
* on `OrmSubscriptionHandle` in `model/types.ts`). And `getOrCreate` POOLS on a key
* built from the shape and the scope alone - no identity in it - so a second virtual
* user asking the same question is handed the FIRST one's live instance. What makes
* that safe here is the filter this package applies on the way out; publishing the
* handle would hand out the instance instead.
* - `DiscreteOrmSubscription` - a JSON-CRDT document. Its items carry no `@graph`, so
* the read filter has nothing to read, and its writes leave through
* `discrete_orm_update`, a third channel nothing here guards. Nothing in this package
* reads or writes a discrete document; publishing it would open a surface and a hole
* in the same gesture.
* - `ngSession` - a module-level PROMISE, not a function, and what it resolves to is
* the SDK handle plus the SESSION. Here one physical session hosts every virtual
* identity, so handing it out hands every identity the same one; the contract already
* says the session is the package's. Wrapping a resolved value would also force a
* RUNTIME `@ng-org/orm` import into this module, which is the one thing the injection
* discipline exists to avoid.
* - `getRaw` - it returns the object BEHIND a signal, which is the same escape hatch
* `read-filter.ts` refuses on a dunder key (`__raw__`): it hands back the unfiltered
* collection, every identity's items in it. There is no filtered form of it.
* - `watch` / `effect` - `@ng-org/alien-deepsignals`' reactivity primitives, not the
* ORM's. They carry no document and grant nothing, so there is nothing to wrap; an
* application that wants them declares that package.
