 ## Prerequisites
 
 - Access to CI/CD configuration files (e.g., `.github/workflows/*.yml`, `.gitlab-ci.yml`, `Jenkinsfile`, `cloudbuild.yaml`).
-- Access to repository settings context (branch protection rules, environment configurations).
-- Read access to dependency manifests and lock files for supply-chain analysis.

+### SLSA v1.0 Build Level Determination
 
-| Level | Requirements | Key Controls |
-|-------|-------------|--------------|
-| **SLSA Build L1** | Documentation of the build process exists. The build process is scripted (not manual). | Build steps defined in version-controlled config. |
-| **SLSA Build L2** | Hosted build platform. Signed provenance generated by the build service. | Builds run on a managed service (GitHub Actions, Cloud Build, etc.). Provenance metadata is produced and signed. |
-| **SLSA Build L3** | Hardened builds. Build environment is isolated, ephemeral, and parameterless. Builds cannot influence one another. | Isolated runners, no shared caches across trust boundaries, hermetic builds, non-falsifiable provenance. |
+1. **Source Code**: Is the source code stored in a version control system?
+2. **Build Configuration**: Is the build configuration defined in a file (e.g., `Dockerfile`, `build.gradle`)?
+3. **Build Process**: Is the build process automated and reproducible?
+4. **Artifact Storage**: Are artifacts stored in a secure and tamper-evident manner?
