 If `obsidian-cli` is unavailable in the local environment, record it in release notes or release-handoff evidence.
 If the change affects diagram semantics, also run the maintainer-local semantic layer in `docs/maintainer/diagram-semantic-verification.md`.
+If the change affects Slidev export wiring, Slidev settings, source preparation, local fork detection, or HTML/PDF/PNG/MP4 export behavior, also run the maintainer-local workflow in `docs/maintainer/slidev-export-workflow.md`:

 npm run verify:diagram-semantics -- --vault "<vault-name>" --commit "<sha>" --version "<plugin-version>" --output ~/tmp/notemd-diagram-check.md
