feat: ontology semantic search layer for agentic queries#50
Merged
Conversation
Implements the MVP for LeanKG ontology to enable semantic search beyond code symbol lookup. Agents can now ask domain-aware questions like "where is checkout refund failure handled?" and get structured context. Features: - Concept ontology: domain_entity, service, api_endpoint, data_store, etc. - Procedural ontology: workflow, workflow_step, failure_mode, playbook - Stable GIDs for idempotent sync - YAML loading for manual ontology definitions - MCP tools: kg_context, kg_concept_map, kg_trace_workflow, kg_ontology_status - CLI commands: ontology validate/sync/status/context/concept-map/trace-workflow - Full test coverage for ontology types, loader, and query engine BREAKING: None - fully additive feature
