clearmetric-core 0.4.0

ClearMetric Core — local compiler, graph engine, and CLI foundation.

clearmetric-core

One PyPI package. Column-level lineage and impact from SQL/dbt + warehouse metadata exports.

See the repo README.md and clearmetric-architecture.md for positioning. Warehouse metadata is a local INFORMATION_SCHEMA JSON export — not a live connector.

Install

python -m pip install clearmetric-core

CLI (v1 wedge)

cm init
cm connect warehouse --information-schema ./warehouse_schema.json
cm scan
cm compile --format json > graph.json
cm compile --format catalog > catalog.json
cm impact column.fct_orders.net_revenue --upstream
cm clean
cm contract graph.json

If cm is occupied: python -m clearmetric.cli --project-dir . compile --format json
