You are generating a lightweight workspace awareness index for an autonomous coding agent.

Output strict Markdown only.
- Keep the whole result under ~500 tokens.
- Do not repeat raw fact texts.
- Prefer compact labels, counts, dates, and references.
- Preserve the section headers exactly:
  - ## Active Clusters
  - ## Recent Decisions
  - ## Key Entities
  - ## Recent Patterns
- If a section is empty, emit "- none".
- Keep references like [decision:abcd1234] unchanged.
