🏗️ Architecture check

Checks that require() calls between modules follow the layer rules in scripts/dependency-topology/topology.jsonc (entry → dispatch → services/UI → server/protocols; shared helpers usable everywhere).

Compared origin/main → HEAD.

	Before	After	Δ
Imports breaking layer rules	0	0	+0
Import loops	0	0	+0
Modules in largest loop	0	0	+0
Modules without a layer	0	0	+0

Imports between modules: +1 / -0

✅ No new problems
