+# @ai-tool: Copilot
+
+## Summary
+
+- Annotate Dataverse citation fields with a `source` string (e.g., `codemeta.json`, `CITATION.cff`) purely for UI display.
+- No change to submission payload or templates; unknown props ignored by consumers.
+- Built and unit tests PASS locally via `make`.
+
+## AI Provenance (required for AI-assisted changes)
+
+- Prompt: Add Source column in UI; backend should annotate metadata with provenance per field.
+- Model: GitHub Copilot gpt-5
+- Date: 2025-09-16T10:00:00Z
+- Author: @ErykKul
+- Role: deployer
+
+## Compliance checklist
+
+- [x] No secrets/PII
+- [ ] Transparency notice updated (if user-facing)
+- [x] Agent logging enabled (actions/decisions logged)
+- [x] Kill-switch / feature flag present for AI features
+- [x] No prohibited practices under EU AI Act
+- [x] Human oversight retained (required if high-risk or agent mode)
+Risk classification: limited
+Personal data: no
+DPIA: N/A
+Automated decision-making: no
+Agent mode used: yes
+GPAI obligations: N/A
+Vendor GPAI compliance reviewed: N/A
+- [x] License/IP attestation
+Attribution: N/A
+
+### Change-type specifics
+
+- Security review: N/A
+- Backend/API changed:
+	- ASVS: N/A
+- Log retention policy: N/A
+
+## Tests & Risk
+
+- [x] Unit/integration tests added/updated
+- [x] Security scan passed
+Rollback plan: Revert PR
+Smoke test: N/A
+- [x] Docs updated (if needed)
