 - **Records are plain data**: immutable, directly JSON-serializable POJOs; values returned by `get`/`entries` must not be mutated in place (TypeScript readonly projection, no runtime freezing). Behavior-carrying domain objects belong to consumer packages.
 - **Serialized writes**: one promise chain per domain; `put`/`delete`/`update`/`global.set` all queue on it; `update`'s fn runs on the chain, so concurrency cannot interleave. No active-record (pulling out a mutable object that auto-persists — uncontrollable persist timing, in conflict with the whole-unit atomic-rewrite model).
 - **Version fails loud**: a stored version differing from the spec throws outright; no migration, no rebuild (the data is not regenerable; pre-release rejects old formats).
-- **Change events**: after each write's durability resolves, emit `domain/changed` (`@mode emit`), one per record, no old value (matching the repository's "new snapshot + operation discriminant" convention, template `goal/changed`); the payload `DomainChanged` is a put/deleted discriminated union — domain + table + key (both `''` for global changes) + operation, with the put branch carrying the new snapshot value and the deleted branch carrying none (`packages/storage/domain/src/events.ts`). This is next phase's RPC push-frame event source. The error vocabulary is `DomainError`, codes: `already-open` / `facet-unsupported` / `invalid-record` (with `{ table, key }`) / `missing-key` / `closed`.

 Domain data form for the DeepSeek Harness storage hub: mounts `ctx.storage.domain`, opening schema-validated KV domains over configured storage backends. A domain is declared once with `defineDomain` (zod record schemas, `z.infer`-derived types), opened through `DomainFacility.open`, and served from authoritative in-memory state — reads are synchronous, writes serialize on one per-domain chain, reach durability on the routed backend first, then update memory and emit `domain/changed`. The opening consumer owns the handle's lifecycle and releases it with `Domain.close()` (idempotent; typically its own `ctx.effect` disposer); domains still open when the plugin unmounts are closed by the facility.
