The bare 'domain' name was too generic for a published package. The directory moves to packages/storage/storage-domain, the package becomes @deepseek-ai/dsh-storage-domain, and the plugin/invariant names follow; the ctx surface (ctx.storage.domain), the domain/changed event, and all runtime behavior are unchanged. References, catalogs, graphs, and the bilingual design note move together.

Cordis Events Catalog
Every cordis event a plugin can listen to: exact signature, dispatch mode, and original declaration JSDoc. This is one axis of the wiring reference a plugin author works against — the callable ctx.<key> surface is the sibling services catalog, and core-data-structures/ catalogs the data structures these signatures move around.
This file is GENERATED from source (scripts/gen-cordis-catalog.ts) and verified fresh by pnpm run verify-cordis-catalog (part of doc-sync) — do not edit it by hand. Signature blocks use a ts cordis-catalog fence and include the original source JSDoc immediately before each event or service method. doc-typecheck skips these bare declaration fragments; type names in a signature link to the page that documents them.
The harness tier below (the @deepseek-ai/dsh-* packages) is the vocabulary this repo owns, grouped by scope. The inherited tier at the end is the cordis-core + loader/hmr/timer event surface a plugin also sees — pinned vendor source, summarized tersely. The event-dispatch methods themselves are generated in the Cordis core Events API.
Dispatch modes: emit (fire-and-forget), waterfall (each listener gets next() and may transform or veto — see waterfall semantics), parallel (awaited fan-out; all listeners run), serial (awaited in registration order until one returns a bail value — anything other than null, false, or undefined).

Inherited events (cordis core + loader/hmr/timer)
The framework events every plugin also sees, beyond the harness vocabulary above. This is pinned vendor source (vendoring policy); it is summarized here so the page is a complete picture of the event bus, without elevating framework internals to the harness tier's prominence.
internal/plugin— A plugin fiber was created. (vendor/cordis/src/events.ts:328)internal/status— A fiber changed lifecycle state. (vendor/cordis/src/events.ts:330)internal/service— Interception hook for a service binding (no core producer). (vendor/cordis/src/events.ts:332)internal/update— Waterfall: a fiber config update is being applied. (vendor/cordis/src/events.ts:334)internal/get— Waterfall: a service is being read from the store. (vendor/cordis/src/events.ts:336)internal/set— Waterfall: a service is being written to the store. (vendor/cordis/src/events.ts:338)internal/listener— A listener was registered.
