> **Verified live 2026-06-07** (OtOpcUa `feat/equipment-namespace-live-values`): galaxy mirror
> **396/396 Good**, company overlay **396 Good** on `opc.tcp://localhost:4840`, `VERIFY-EQUIPMENT: PASS`.
> Why 396 of 1036? The shipped `company-uns.json` invents **1036 distinct** `ctx.GetTag` refs, but only
> **396** of them match a real galaxy-mirror tag — so 396 signals are backed by a live source (and all 396

> property of the company model, not the streaming path — **every signal with a resolvable live source
> streams Good.** So `--require-good 396` is the meaningful gate for the current model. Survives a node
> restart with no re-deploy (the bootstrap-restore path re-materialises + re-applies the VirtualTags).
UNS folders carry the friendly **DisplayName** (`filling`); the BrowseName/NodeId
stay the stable logical Id (`nw-area-filling`) — standard OPC UA. **No driver:** the
company signals are VirtualTags (which link to Equipment + a Script, not a driver); a
