Nothing was redrawn

Cedar Street Building A, exported by one system and rendered by another. The geometry, the symbol roles, the live points and the command writes — with their priorities and safety references — all travelled in the package. The receiver supplied only its own artwork.

Cedar Street Building A — imported into Meridian Ops

Rendered by busref acting as a receiving vendor (“Meridian Ops”) directly from the exchange package. Geometry, element identity, and every binding came from the package; every color, symbol shape, and animation is the receiver’s own. Amber badges mark write-capable elements with their command priority, preserved verbatim per 13.7-1.

What the package carried

Drawing geometry, layers, symbol roles, a georeferenced floor plan, eleven bindings, and two command writes — a supply-air setpoint at priority 10 referencing the freeze-protection constraint, and a fan command at priority 8 referencing the fire interlock.

What the receiver chose

Every pixel of the artwork, the dark palette, the type, the layout, the animation, and the quality styling. None of it was in the package. None of it needed to be.

What would degrade

A receiver missing damper.controlDamper truncates to damper and reports the substitution. A receiver with no prioritised write mechanism carries the priority and reports it unenforced. Neither silently pretends.
