Equipment folder DisplayName was the colloquial MachineCode; the live rebuild (artifact
ReadEquipmentNode) + composer now use the UNS level-5 Name segment, matching Area/Line
folders + EquipmentNodeWalker. NodeId stays the logical EquipmentId so browse-path
resolution + ACLs are unaffected.
Add Phase7Applier.MaterialiseEquipmentTags — a sink-based pass (Task-0 decision A) that
ensures each EquipmentTagPlan's Variable (NodeId = FullName) under its existing equipment
folder, nesting any FolderPath as a sub-folder. Wire it into OpcUaPublishActor.HandleRebuild
after the Galaxy pass. Variables start BadWaitingForInitialData; never re-creates equipment
folders (decision #4).
Add EquipmentTagPlan + an init-only EquipmentTags member on Phase7CompositionResult
(mirror of GalaxyTags). Populate it compose-side (Tag.EquipmentId != null AND owning
namespace Kind == Equipment) and artifact-decode-side via BuildEquipmentTagPlans, with
FullName extracted from Tag.TagConfig. Init-only member (not a 7th positional param) so
existing convenience constructors + call sites are untouched.
Implements WS-1/WS-2/WS-4 (+ tests) of the materialization scope: carry
Equipment-namespace tags through the composition/artifact, add a sink-based
MaterialiseEquipmentTags pass to the live rebuild, browse folders by friendly
Name (NodeId stays the logical Id). 6 tasks with dependencies; structure-only
(BadWaitingForInitialData leaves) — live values are the next milestone. Resume
via /executing-plans docs/plans/2026-06-06-equipment-namespace-structure-milestone.md
