+### CI artifacts
+
+Successful CI conformance runs publish downloadable workflow artifacts:
+
+```text
+comparison-result.json
+comparison-report.md
+```
+
+`comparison-result.json` is the machine-readable comparison result generated by `npm run vsc -- compare:fixtures --json`. `comparison-report.md` is a small human-readable summary of the same CI comparison result. These artifacts make CI conformance results easier to inspect and archive.

+# VSC v2.10 — CI Artifact Upload
+
+Release: v2.10  
+Project: DigiEmu VSC / VSC Core
+
+## Summary
+
+VSC v2.10 extends the CI conformance workflow introduced in v2.9.
+
+The workflow now preserves the machine-readable comparison result as a downloadable GitHub Actions artifact.
+
+This makes CI conformance runs easier to inspect, archive, and reference.
+
+## Added
+
+CI artifact upload for:
+
+```text
+comparison-result.json
+comparison-report.md
+```
+
+`comparison-result.json` is generated by:
+
+```powershell
+npm run vsc -- compare:fixtures --json
+```
+
+`comparison-report.md` is a lightweight human-readable report generated from the JSON comparison output.
+
+## CI behavior
+
+The workflow still validates:
+
+```powershell
+npm run vsc -- compare:fixtures
+npm run vsc -- compare:fixtures --json
+npm run vsc -- verify-all
+```
+
+CI fails unless the comparison JSON reports:
+
+```json
+{
+  "result": "COMPARE_PASS"
+}
+```
+
+## Unchanged
+
+v2.10 does not change:
+
+- Go verifier semantics
+- Node runner comparison semantics
+- Conformance fixture expected results
+- PASS / FAIL / ERROR meaning
+- Evidence bundle verification logic
+
+## Release meaning
+
+v2.10 makes CI conformance output more auditable by preserving both machine-readable and human-readable comparison artifacts.
+
+It continues the path from local verification to automated, inspectable repository-level conformance checks.
+
+## Next possible step
+
+```text
+v2.11 — CI Badge / README Conformance Status
+```
