Columna, by datumwise — honest data framework
Columna is an honest data framework: 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
Requires Python 3.10–3.13, 64-bit.
If pip says "no matching distribution found for columna" — you are almost certainly on Python 3.14, or on 32-bit Python.
columna-coredepends ondatasketchesfor HLL, and datasketches 5.x publishes no 3.14 wheels on any platform and no 32-bit Windows wheels at all. We declarerequires-python = ">=3.10,<3.14"so pip refuses cleanly instead of dropping you into a C++ source build that fails minutes later. Install into a 3.10–3.13 64-bit interpreter. Python 3.14 support arrives when datasketches ships cp314 wheels, or via the optional-extras split already scoped as WP-1.1.
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.
