 Workflow install target is configured as:
 
 ```text
-github.com/valkdb/valk-guard/cmd/valk-guard@latest
+github.com/valkdb/valk-guard/cmd/valk-guard.0.0-20260304065917-b9d9468a4ea3@latest
 ```
 
 Rationale:
 
-- This repository is a demo showcase; tracking latest keeps examples aligned with current built-in behavior.
-- If you need strict reproducibility, pin a fixed tag in workflow `VALK_GUARD_INSTALL_REF`.
+- This repository is a demo showcase, but CI is pinned to a known-good valk-guard build to keep output shape stable.
+- Pinning avoids format drift that can break downstream tooling steps (for example: `Convert to reviewdog format`).
+- When upgrading, bump `VALK_GUARD_INSTALL_REF` intentionally and verify the full workflow output.

+# Dist 3: VG007, VG008, VG101-VG105
+
+This demo bundle intentionally triggers:
+
+- VG007 (destructive DDL)
+- VG008 (non-concurrent index)
+- VG101 (model column missing in migration)
+- VG102 (required migration column missing in model)
+- VG103 (model/migration type mismatch)
+- VG104 (explicit model table not found)
+- VG105 (unknown projection column)
+
+Coverage in this bundle:
+
+- SQL migrations and SQL queries
+- Python ORM models (schema drift)
+- Python non-ORM query execution
