Concepts

  • Decision graph - The questions asked from a dataset card to a written AVU, and what decides each.
  • Levels and policy - AnyJev levels, the calibration field, and how a decision becomes auto, proposed or abstain.
  • Provenance - The sidecar that records every decision next to the mesa-ducklake AVU history.
  • Learning - Label sources and weights, leave-one-card-out fitting, the guards, promotion.
  • MCP tools - The mesa_decide_* tools inside mesa-mcp, one question per round trip, picks as labels.
  • Second opinions - Claude as a recorded second opinion, specificity over child terms, the planner audit.
  • DataCite decisions - The frozen DataCite vocabularies as questions and the record fragment for mesa-mcp.
  • Hosted providers - Hosted Jev through MotherDuck prompt_jev and the data-residency switch.
