v0.2.30

Changed

• Engine floor moves to kglite 0.19.6 (from 0.19.4, taking 0.19.5 with it).
  The Python requirement is now kglite>=0.19.6,<0.20 and the Rust
  requirements for kglite and kglite-mcp-server are 0.19.6. None of the
  breaking changes in 0.19.5 and 0.19.6 reaches codingest's code or output:
  • Enforced ontologies (enforcement: warn|error) bind writes only on a graph
    that declares one. The builder declares no ontology, so builds are unchanged.
  • The new KgError / KgErrorCode variants, the OntologyStore fields and
    CommitOutcome no longer being UnwindSafe need no source edit: codingest
    only boxes a KgError and never matches it.
  • Unaliased RETURN items are now named by their source text. The
    codingest query and MCP tools pass columns through from the engine, so
    an unaliased column in a user's query is named by its source text; alias
    with AS for stable names.
  • The workspace compiles unchanged and the frozen parity goldens are
    unchanged.
