trustline 0.1.0

Open-source trust layer for data products — machine-checkable contracts across ETL, ML, and delivery seams.

Trustline

CLI for validating YAML data-product contracts and running a five-phase trust audit (DuckDB or Snowflake).

Quickstart

pip install trustline
trustline validate --contracts ./examples/acme_stream/contracts/
trustline audit \
  --contracts ./examples/acme_stream/contracts/ \
  --target duckdb \
  --profiles ./examples/acme_stream/profiles.yml.example

Clone the repository to run the bundled ACME Stream fixture locally:

git clone https://github.com/omarfarooq908/trustline.git
cd trustline
make install-dev
trustline audit \
  --contracts ./examples/acme_stream/contracts/ \
  --target duckdb \
  --profiles ./examples/acme_stream/profiles.yml.example

The example audit exits 1 — the fixture intentionally includes failing checks.
