+# CI/CD Workflows
+
+## Main CI (single job)
+
+| Workflow | Trigger | Purpose |
+|----------|---------|---------|
+| **ci.yml** | PRs and pushes to `main` / `develop` | One job: Python 3.12, pytest + ruff (check + format) + mypy + integration tests (`test_templates.py`). Single green check per run. |
+
+All testing and linting for PRs and main/develop runs in this one workflow. No matrix, no separate “Enhanced” or “PR Tests” jobs.
+
+## Other workflows
+
+| Workflow | Trigger | Purpose |
+|----------|---------|---------|
+| **publish.yml** | Release | Publish package. |
+| **ci-error-analysis.yaml** | — | Error analysis (if used). |
+
+## Removed (consolidated into ci.yml)
+
+- **pr-test.yml** — merged into ci.yml
+- **test-enhanced.yml** — matrix and reporting removed; single Python 3.12 in ci.yml
+- **test.yml** (Push Tests) — same steps now in ci.yml on push
+- **integration-tests.yml** — integration step runs inside ci.yml
+- **feature-test.yml** — removed; open a PR to run CI on feature branches
