# Risks

1. **CRITICAL to migration confidence:** semantics of 218 796 are not present in this source tree.
2. **HIGH:** 25 projects bind to AutoCAD/Plant 3D 2019 assemblies and hard-coded HintPath.
3. **HIGH:** batch operations touch multiple drawings and many entities; partial write/undo behavior is unverified.
4. **HIGH:** programmatic Ribbon/project event lifecycle has incomplete unsubscribe and possible duplicate registration.
5. **HIGH:** custom blocks/settings and external network support files are part of behavior but not versioned with a safe contract.
6. **MEDIUM:** archive and release copies duplicate commands and can confuse static inventory.
7. **MEDIUM:** empty catches and MessageBox-based errors make failures difficult to audit.

No conclusion that the plugin is obsolete is justified by this static audit.
