Plan's digital-twin scope is now exactly (1) environment-lifecycle
promotion via ACL flip on write authority and (2) safe read-only
consumption for KPI / monitoring systems — both delivered by
already-committed architecture. Removes the meeting-prep brief and the
management-delivered use-cases source document; canonical model and
state vocabulary stand as pillar-2 work on their own.
The OtOpcUa v2 implementation team committed all 8 core drivers from
internal knowledge of the estate, making the formal protocol survey
unnecessary for driver scoping. Removed current-state/equipment-protocol-
survey.md and cleaned up all references across 7 files.
The UNS hierarchy snapshot (per-site equipment-instance walk for site/area/
line/equipment assignments + UUIDs) is now a standalone Year 1 deliverable,
decoupled from protocol discovery. Tracked in status.md and goal-state.md
UNS naming hierarchy section.
Eliminates ~52 TBDs (all placeholder data in the pre-seeded survey rows).
