Check cluster events with `kubectl describe`.

Change replicas with `kubectl scale`.

M3.6.2 — Level R Reference Storage — Summary

Components Tested:
  a1: Obsidian file listing & filtering
  a2: Reference record format (level R, no query_id)
  a3: Heading-boundary chunking
  a4: Rebuild parity (byte-identical)
  a5: No edges from R nodes
  a6: Document SHA stability
  a7: Chunk SHA uniqueness
  a8: Breadcrumb path formation
  a9: Obsidian URI format (obsidian://)
  a10: Query_id exclusion on R
  a11: Dual-write (Postgres + OpenSearch)
  a12: API batching efficiency

Implementation Ready: ObsidianRefSource + rebuild parity validation
