Phase 1d of the v2 entity-model rewrite. The static RedundancyRole column
is replaced by Akka cluster's role-leader-of-"driver" election at runtime
(see RedundancyStateActor + ServiceLevelCalculator in Task 35).
Changes:
- Removed `public required RedundancyRole RedundancyRole` from
ClusterNode entity.
- Removed `e.Property(x => x.RedundancyRole).HasConversion<string>()...`
mapping from OtOpcUaConfigDbContext.ConfigureClusterNode.
- Removed the `UX_ClusterNode_Primary_Per_Cluster` filtered unique index
(filter referenced [RedundancyRole]='Primary').
- Dropped `using ZB.MOM.WW.OtOpcUa.Configuration.Enums` from ClusterNode.cs
(no longer needed).
- Deleted `Enums/RedundancyRole.cs` — the enum is unused in v2-kept code.
- DraftValidator: dropped the "exactly one Primary per cluster"
validation block. Comment in place explaining v2 picks primary at
runtime via Akka.
- DraftValidatorTests: dropped ValidateClusterTopology_flags_multiple_Primary
test; reworked BuildNode helper to no longer take a `role` argument.
Untouched (Server + Admin still reference RedundancyRole; accepted broken
per Task 56 policy):
src/Server/ZB.MOM.WW.OtOpcUa.Server/Redundancy/{ClusterTopologyLoader,
RedundancyStatePublisher, RedundancyTopology, ServiceLevelCalculator}.cs
src/Server/ZB.MOM.WW.OtOpcUa.Admin/Services/RedundancyMetrics.cs
DB-runtime tests will fail against the new schema (Task 14f's migration
drops the column) — to be updated in Task 14f's SchemaComplianceTests
update:
- SchemaComplianceTests.cs:55 (expected filtered index list)
- StoredProceduresTests.cs:263 (raw INSERT names the column)
Verification:
src/Core/ZB.MOM.WW.OtOpcUa.Configuration -> 0 errors
tests/Core/ZB.MOM.WW.OtOpcUa.Configuration.Tests -> 0 errors
whole solution -> 71 errors
(70 from Task 14b in Server/Admin, +1 new Server/Redundancy reference)
