New `EquipmentTagConfigInspector` in ControlPlane + `AdminOperationsActor` deploy-gate wiring with `Deployment:TagConfigValidationMode` (**Warn default | Error opt-in**), proven through the actor (F10b consuming test). AdminUI: `writable` checkbox in the six typed editors. **Phase-C follow-up (deferred, recorded here):** flip the runtime parsers to strict (typo'd enum ⇒ `BadNodeIdUnknown` instead of wrong-width `Good`) once fleets have run `Error` mode clean — behavior change deliberately not shipped in this plan. **Deferred (T22/T24):** docker-dev `/run` of one typed editor's Writable checkbox + whole-solution serial sweep. |

Adds are announced via a new `ComputeAddAnnouncements`+`AnnounceAddedNodes` (dedup affected-parent set → existing guard-covered `RaiseNodesAddedModelChange`), fired by `OpcUaPublishActor` after the 4 Materialise passes gated on `!outcome.RebuildCalled`. `MaterialiseAlarmCondition` made idempotent (skip-if-present-and-same-kind ⇒ keeps the condition NodeState alive across a pure-add).
