+# Runs automatically on every pull request (any branch).
+#
+# Pipeline
+# --------
+#   1. go-tests         Run the full Go test suite with race detector and
+#                       coverage report, publish results to the job summary.
+#   2. deploy-and-e2e   Build the all-in-one Docker image from the PR branch
+#                       (local build only — never pushed to Docker Hub), start
+#                       it as an isolated test container, run all Python E2E
+#                       tests against the live container, collect benchmark
+#                       results, publish a benchmark table to the job summary,
+#                       then unconditionally tear the container down.
+#
+# This workflow never touches the production 'deltadatabase' Kubernetes
+# namespace and does not require KUBE_CONFIG or any cluster credentials.
+# Each run uses a unique container name and shared-filesystem path derived
+# from the run ID so concurrent PR builds cannot collide.
+#
+# Required on the self-hosted runner:
+#   - Go 1.25+  (already present - used by docker-publish.yml)
