fix(migrations): merge the two Alembic heads#3
Merged
Conversation
The fork had two migration heads (2b8f88aa610f reconcile-squash and a2b3c4d5e6f7 person software/hardware links), which makes 'alembic upgrade head' fail with 'Multiple head revisions are present'. Because the upgrade aborts, the schema from the reconcile branch never applies and the app crashes at runtime with 'column person.is_guest does not exist'. Add an empty merge migration joining both heads so the upgrade can run and apply both branches. No schema change of its own. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
