Project description
Columna, by datumwise — honest metrics engine
Columna is an honest metrics engine: a grammar layer for analytics that serves a number and its disclosure together — serve, disclose, clarify, refuse — so an AI agent (or a person) never receives a plausible-but-wrong answer with no way to tell.
This package (columna) is the metapackage: the canonical one-line install of the whole system.
pip install columna
It installs:
columna-core— the column-foundation engine (multi-table, transport-based, correctness-governed): the Manifold object model, Frame-QL, the four moods, and the Certificate kernel.columna-server— the read-only MCP server and the natural-language query agent over one wire contract.
The implementation lives in those packages; import from columna_core and columna_server. The
metapackage carries no code of its own beyond a version that rides in lockstep with columna-core.
