SnowBridge now owns machine-data ingest, in-process .NET transformation,
and direct writes to curated tables in Snowflake. Collapses the previous
ingest/transform split into a single service; no dbt, no external
orchestrator, no Snowflake landing tier. Keeps the in-house .NET pattern
consistent with ScadaBridge and OtOpcUa.
The "Snowflake dbt Transform Layer" roadmap workstream merges into
SnowBridge (7 → 6 workstreams); Year 2 canonical-state-based OEE moves
with it. Canonical model still has three surfaces — the third is
renamed from "dbt curated layer" to "SnowBridge curated layer in
Snowflake"; mechanics unchanged.
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.
Session bookmark updated: captures all work done 2026-04-15 through
2026-04-23, removes stale session ID (new session will self-orient from
CLAUDE.md + status.md), updates resume flow for a fresh start.
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).
