How it's graded

Retrieval is graded by an eval harness: a hand-written golden set of questions plus off-corpus probes the agent must refuse. The scorecard below renders whatever the last recorded run measured, never a number that wasn't.

Guardrails ↓
  • · Answers only from the indexed corpus (case studies, writing, resume).
  • · Never invents employers, dates, or metrics.
  • · Refuses if the reranker scores every excerpt below threshold.
  • · Speaks about Owen in third person. It is a tool, not him.
  • · Rate-limited to 10 questions per IP per hour.
