+## Post-Completion Q&A — CI Concurrency Cancellation
+
+**Timestamp**: 2026-08-02T17:50:00Z
+
+**User Input**: "Ja, commit alle openstaande wijzigingen. Is het trouwens mogelijk een workflow run te stoppen als er een nieuwe push wordt gedaan naar de pull request of zou dat al moeten gebeuren?" — followed by "Ja, voeg maar toe" after being told this isn't automatic and being shown the fix.
+
+**AI Response**: "Committed the Operations-phase doc changes (commit `81af6cd`, not pushed). Answered the concurrency question: confirmed via the Gitea server's `/api/v1/version` (1.27.0, well past when Gitea Actions gained `concurrency:` support) that neither Gitea nor GitHub Actions cancels a previous run on a new PR push by default — each `synchronize` event starts an independent run. Added a workflow-level `concurrency` block to `continuous_integration.yaml`, scoped to only cancel on `pull_request` events (`cancel-in-progress: ${{ github.event_name == 'pull_request' }}`) — verified `deploy-test`/`deploy-production`'s existing `if:` conditions never trigger on a `pull_request` event (only push-to-master or `workflow_dispatch`), so this can never abort a live deploy mid-flight."
+
+**Context**: Post-completion CI/CD hygiene improvement, within this feature's already-established Operations-phase scope (it already owns the retargeted `continuous_integration.yaml`). Not yet committed — awaiting the user's decision on whether to fold this into a new commit or the next one.
