+## iAiFy Fork Notes
+
+> This section is maintained by the iAiFy enterprise and documents what the AiFeatures fork actually supports. If this contradicts upstream text above, this section wins for iAiFy operators.
+
+**Status:** Active fork (maintained).
+**Enterprise:** iAiFy (Stockholm).
+**Upstream sync:** Managed via [Ai-road-4-You/fork-sync](https://github.com/Ai-road-4-You) — upstream changes are reviewed before merge; divergence is intentional where documented.
+**Support scope:** Only the build/run paths documented below are supported internally. Other upstream surfaces are best-effort.
+
+### Supported commands
+
+Run only the commands verified in this repo's current manifest (see `package.json` / `pyproject.toml` / `Cargo.toml` for the authoritative list).
+
+### CI/CD
