commons is a constructor for trustworthy data agents. Once implemented, this package will give an LLM data, semantic, and context layers to work with, tools for querying them, and A/B/C provenance tags so every answer carries a classification as to its trustworthiness.

Status: pre-alpha. The package installs, imports, lints, type-checks, and tests, but exports nothing yet: commons.__all__ is empty and there is no public API. Python 3.11 or later is required.

Behavior that both implementations must agree on belongs in tests/shared/ at the repository root, which that directory's README defines as the authority. The provenance tag rules and display copy are the first behavior governed that way; both suites run those cases.
