EXTENSIONS

A domain-neutral, sourced, versioned knowledge base — the provenance-aware core generalised out of @stateless/llm-catalog. One uniform `entry` record (open `kind` + open `facets` + `claims` + `relations`, like @stateless/inventory), but with a provenance envelope (asOf, source, versionPins, supersededBy) on every volatile assertion, so it can hold external, decaying, contested knowledge honestly — a value without a date + source is not trustworthy here. Declarative lifecycle: `apply` materialises the declared entries (re-run = versioned trend), `update` folds in a public catalog without clobbering local truth, `prune` soft-retires undeclared entries, `contribute` sanitises selected entries into PR-ready public fragments. It knows no domain (no typed facets, no compute methods); a consuming catalog — LLM-ops, cloud-storage pricing — is an instance whose entries carry that domain's kinds and facets.
