0.16.0 - 2026-09-29

Release Notes

Full detail: docs/releases/0.16.0.md.

Upgrading

• First start migrates entities (issue #615). Entity gains a kind column and lookup_key
  becomes group_id ␟ kind ␟ lower(name). A one-time backfill sets every existing entity to kind
  Entity and re-keys it (O(N), automatic). It also normalizes labels to put Entity first
  (e.g. [Object, Entity] → [Entity, Object]); the label set is unchanged. Downgrade is
  unsupported: a pre-#615 binary cannot replay a WAL written after this change (lookup_key is
  no longer written to the WAL).

Added

• Ontology-driven kind assignment (ADR-0616,
  #616, follows #615). An entity type marked identity: true in the ontology is assigned as the
  kind of entities extracted with that primary type, so Person "Aurora" and Technology "Aurora" stay distinct; unflagged types (and every existing ontology) merge by name exactly as
  before. Per group, the identity-bearing set is recorded in .lcg/identity-set/<group>.json, and
  a change that would reinterpret existing entities (flag added or removed for a type the group
  already holds) is refused for that group's knowledge_add_episode with JSON-RPC -32003 —
  restore the set or re-ingest from source. knowledge_reprocess_entity_types never changes kind
  and reports kind_disagreements; knowledge_status gains group_identity_refusals.
  Edge endpoints whose name is ambiguous across kinds are dropped rather than guessed.
• Kind-scoped entity identity (ADR-0615, #615,
  implements #614). Same-named entities of different kinds now coexist instead of the second
  knowledge_assert_entity overwriting the first. knowledge_assert_entity takes kind
  (omitted ⇒ default kind Entity only — writes are scoped); knowledge_assert_relationship takes
  source_kind/target_kind; new read tool knowledge_resolve_entity; kind filter on
  knowledge_find_entities/knowledge_list_entities; kind on knowledge_merge_entities;
  source_kind/target_kind (stored as pointer endpoint_kind) on
  knowledge_add_cross_group_edge. A name-only resolution matching several kinds fails with
  JSON-RPC -32002 and a candidate list. Merges never cross kinds. Every entity node now carries
  kind (additive).

Changed

• lbug 0.20.3 → 0.21.0, with version-matched v0.21.0 extensions (#619). Upstream's 2026-09-29
  republish of the v0.20.0 extensions left 0.20.3 with no safe Windows fts pairing (see ADR-0593
  addendum). 0.21.0 extensions are published per-version and pinned in LBUG_EXTENSION_HASHES.
  Storage version stays 47: no database migration.

• Release builds verify the staged lbug extension bytes against pinned sha256 (#593); Windows CI
  now creates and queries vector/FTS indexes rather than only loading the extensions (#587).

• lookup_key is a derived value: stripped from WAL records on write, recomputed on replay; a
  literal lookup_key in an older WAL is ignored. Old WALs replay as kind Entity.
