| # Rechenaufwand-Score: R=2 (K=2, L=2, N=2) | last-calibrated: 2026-08-25 | |
| # Trigger policy: repo framework score calibration for workflow cost controls. | |
| # Enforces dependency hash integrity and SBOM consistency. | |
| # Detects supply-chain tampering and divergence from approved SBOM versions. | |
| # Ensures SBOM reflects edition-correct dependencies (no private plugin leakage in SBOM). | |
