Phase 1a of the v2 entity-model rewrite. Adds:
public byte[] RowVersion { get; set; } = Array.Empty<byte>();
and the EF Core mapping
e.Property(x => x.RowVersion).IsRowVersion();
to 12 live-edit entities:
Equipment, DriverInstance, Device, Tag, PollGroup, Namespace,
UnsArea, UnsLine, NodeAcl, Script, VirtualTag, ScriptedAlarm
These are the entities that v2 admins will edit directly via
AdminOperationsActor (no draft staging). RowVersion enables
last-write-wins detection when two operators race on the same row.
GenerationId FKs are still in place on these entities (removed in Task 14b);
this commit only adds the rowversion column so the migration in Task 14f can
emit ADD COLUMN before DROP FK as a single atomic step.
Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
