- `isScopeCarrier(value)` / `carrierKeyOf(value)` Runtime carrier marks, used by the dev invariants to assert every scope-filtered dispatch carries a carrier keyed to the subject its arguments name.
- `ScopeLayer` Aggregate contract for one registry's complete global or exact-scope contribution; `isEmpty()` controls scoped-layer reclamation.
- `ScopedLayers<L>` Own one eager global layer and lazy exact-scope layers. `peek()` never creates, `merge()` materializes insertion-ordered named shadows, and `effect()` derives visibility and ownership from the same context while returning the exact Cordis disposer.
- `NamedEntries<V>` Insertion-ordered named storage with caller-owned duplicate diagnostics, live lookup/iteration, and an idempotent exact-entry undo from `insert()`.
- `AnonymousEntries<V>` Insertion-ordered anonymous storage whose unique internal keys keep equal values as independent registrations; `append()` returns an idempotent exact-entry undo.
- `NamedEntries<V>` Insertion-ordered named storage with caller-owned duplicate diagnostics, lookup, and live iteration within one nonempty table generation; draining the table detaches existing iterators from later insertions, and `insert()` returns an idempotent exact-entry undo.
- `AnonymousEntries<V>` Insertion-ordered anonymous storage whose unique internal keys keep equal values as independent registrations; it uses the same drained-generation iterator boundary, and `append()` returns an idempotent exact-entry undo.
The optional `@deepseek-ai/dsh-scope/invariant` companion owns that runtime assertion. It uses the generated `scoped-events.generated.ts` resolver map to require a carrier for every declared scoped event and, when the payload exposes its routing subject, require identity with the carrier key. The Program-backed generator derives the map from event declarations and real `scopeTarget(base, key)` calls.
