The original Task 14 (5-min EF migration that "drops ConfigGeneration") was
under-scoped: the design doc (live-edit model, ~line 208) requires removing
GenerationId from 13 entities (Equipment, DriverInstance, Device, Tag,
PollGroup, Namespace, UnsArea, UnsLine, NodeAcl, Script, VirtualTag,
ScriptedAlarm) and adding RowVersion columns for last-write-wins detection.
That cascades into GenerationApplier / GenerationDiff / GenerationSealedCache
and the legacy Server/Admin CRUD services.
New decomposition (~85 min total, replacing the original 5-min estimate):
14a standard 10m Add RowVersion to live-edit entities
14b high-risk 30m Drop GenerationId FK from those entities
14c high-risk 20m Obsolete GenerationApplier/Diff/SealedCache
14d standard 5m Drop ClusterNode.RedundancyRole
14e small 5m Delete ConfigGeneration + ClusterNodeGenerationState
14f high-risk 15m Consolidator: generate V2HostingAlignment migration
Policy decision (recorded with user): OtOpcUa.Server + OtOpcUa.Admin are
allowed to fail-to-compile between 14b and Task 56 - only the new v2 projects
need to stay green. Task 56 deletes the legacy projects.
Plan markdown: replaces the original Task 14 section with the 6-task
decomposition + a header explaining the rewrite. Task index table at the
bottom of the plan updated.
Tasks JSON: replaces the single Task 14 row with 6 string-id rows
("14a", "14b", ..., "14f"). Task 15 (Migrate-To-V2.ps1) and downstream
consumers re-pointed at "14f".
Verification step in 14f rewritten to use the shared docker host at
10.100.0.35 per CLAUDE.md (Docker is not installed on this Mac dev VM).
