coldstate_batch_search
Run several knowledge-base queries in one call against a single consistent kb_snapshot. Returns each query with its ranked results â efficient and snapshot-consistent across the whole batch.

coldstate_browse_documents
Browse documents in a ColdState index. Indexes are zero-knowledge, so each document is returned as your ref_id plus its state classification and E-score â no stored text. Map ref_id back to your own content.

coldstate_fetch
Fetch a single knowledge-base entry verbatim by its stable id (e.g. "eng_000229f438f7cebd"). Deterministic retrieval â returns the full record plus a content_hash and kb_snapshot for reproducible citation.

coldstate_isomorph
Cross-domain structural analog: given a knowledge entry id, find its closest structural twin in each OTHER domain ("same structure, different domain"). Deterministic. Use coldstate_resolve to turn a name into an id first.

coldstate_related
Find knowledge entries deterministically related to a given entry id via ColdState's concept-cluster graph. Returns same-cluster and neighboring-cluster entries, each tagged with its relation and a cross_domain flag. Same id â same neighbors.

coldstate_resolve
Resolve a name, alias, or surface form to its canonical ColdState knowledge entry (id + title). Deterministic: an exact title match wins, else the top relevance-Ψ entry. Returns the canonical entry plus alternatives. Use the returned id with coldstate_fetch / coldstate_related.

coldstate_search
Search a ColdState index by collection name or index ID. Returns ranked results with Ψ scores and state classification (CRYSTALLINE/FLUID/REACTIVE/DECOHERENT). Provide exactly one of `collection` or `index_id`.

coldstate_search_global
Search ColdState's global knowledge base (48.4M+ entries across 35 domains including SCIENCE, MEDICINE, TECHNOLOGY, HISTORY, etc). Returns deterministically ranked results with Ψ relevance scores and a state classification. Optionally filter by domain.

coldstate_verify
Verify a previously-cited knowledge fact is unchanged. Provide the entry id and the content_hash you stored earlier; returns whether it still matches the current knowledge base. The trust primitive for AI-to-AI fact-checking.
