• Splits source -> sink matrix execution into mock_contract, mock_local, and vendor_live layers.
• Adds credential-free integration_matrix_mock coverage and keeps vendor credentials limited to explicit live gates.
• Extends the manual integration workflow to start local Postgres, ClickHouse, MSSQL, Kafka, and Schema Registry services.
• Adds testing runbooks for matrix triage and local MSSQL wide-type strategy testing.

Verification highlights:

• ruff check, ruff format --check, mypy.
• Matrix contracts and mock_local preflight: 80 local-capable cases + 20 documented BigQuery cases skipped in mock mode.
• pytest -m "not integration_live": 666 passed, coverage 72.61%.
• mkdocs build --strict.
• uv build, twine check, fresh dpone[full] install smoke.
