The PreBuild targets ran the generator with "--no-build", so it used whatever assemblies happened to sit in its output folder. When that copy of the data model was older than a newly added type, the generator regenerated the checked-in *.Generated.cs files WITHOUT that type and overwrote them in the source tree. Nothing failed at build time: the C# compile stayed green and docker builds (-p:ci=true) skip the generator entirely, so they compiled whatever was in the tree. The damage only surfaced at runtime, when EF validated the model and found the inherited GameConfiguration.CastleSiegeConfiguration navigation pointing at a keyless type - the server died on startup with "The entity type 'CastleSiegeConfiguration' requires a primary key to be defined". Dropping the switch makes the generator build first, so its output always matches the data model. The regenerated files here are that missing output: the Castle Siege mappings, and the packet tests for packets whose XML was already committed. TypedContextModelTests builds the typed context the startup reads its plugin configurations through - the first one to touch the model - so this class of breakage fails in seconds without a database.
