Coframe

A grammar-layer framework for analytical data, designed for AI-native analytics.

Coframe is the query layer where silently wrong answers become structurally impossible. It sits between your data and the analysts, BI tools, and AI agents that consume it — answering analytical questions either correctly, with explicit annotations on how the answer was produced, or refusing to answer with a structured diagnostic explaining why the question was ambiguous.

What's distinctive

  • Cross-grain navigation that's automatically correct. Ask SUM(revenue) BY region and Coframe picks the right schema, applies the right aggregation, and returns the right answer — whether your warehouse has revenue at transaction grain, at store-month grain, or at both. The Multi-Table Invariance theorem guarantees they agree.
  • Wrong answers aren't a class of outcome. Either Coframe returns a verified-correct result with attestation annotations, or it refuses the query with a diagnostic. There's no third "looks plausible but is silently incorrect" outcome that semantic layers and text-to-SQL both quietly produce.
  • Designed for AI agents from the foundation. The family vocabulary, the (entity, family, operator) triple, the dubious-query mechanism, and the MCP integration mean an agent can express analytical intent without having to construct joins, group-bys, or NULL handling — the framework handles those structurally.
  • Verification levels (A / AA / AAA). Every AC publishes its rigor posture as an ordinal level — the WCAG-of-analytics. Consumers (humans, BI tools, agents) branch on the level when deciding how much to trust a result.
