# ARCHITECTURE NOTE: CI/CD PIPELINE REFACTOR
#
# This file is a placeholder to explain the new Cloud Build structure.
# Do not add build steps here.
#
# 1. SINGLE SOURCE OF TRUTH:
#    The definitive pipeline for the OPAX-MCP service is now defined in:
#    /cloudbuild.opax-mcp.yaml
#
# 2. REUSABILITY:
#    - To promote clarity and reuse within the pipeline, `cloudbuild.opax-mcp.yaml`
#      uses YAML anchors (&) and aliases (*) for common steps like policy checks,
#      building, and deploying.
#
# 3. BRANCH-AWARE LOGIC:
#    - The pipeline is fully branch-aware. It tags images with both commit SHA and branch name.
#    - Deployment to Cloud Run is conditional and only runs for specific branches
#      (e.g., `main`, `opax-*`).
#
# 4. DEPRECATED FILES:
#    - `cloudbuild.yaml` and `cloudbuild.mcp.yaml` are deprecated. They have been
#      emptied and point to the new pipeline file.
