async:
  pattern: task-id-polling
  notes: >-
    Long-running AI/analysis operations (novelty search, FTO, solution exploration, report
    generation) return a task_id; the client polls a query/status endpoint until completion.
streaming:
  content_type: text/event-stream
  notes: LLM/chat endpoints (cc-gpt, pat-gpt, pharm-gpt, bio-pharma Q&A) stream via SSE.
pagination:
  style: limit-offset
  notes: >-
    Search endpoints accept explicit limit/offset-style parameters; aggregate/faceted
    analysis endpoints cap one-dimensional field analysis (e.g. limit 500).
idempotency:
  supported: false
  notes: >-
    No Idempotency-Key header or documented idempotency contract found. Search and data-read
    operations are naturally idempotent, but write/AI-generation operations use task_id
    de-duplication rather than a client idempotency key.
