forked from 1b-agent/opencadstudio-upstream
acadrust follows hakanaktt/acadrust main through #107, entity-record passthrough included; cadkernel pins the same codec rev so one acadrust stays in the graph. Upstream added BlockFlags::is_xref_unloaded, which XATTACH now sets to false for a freshly attached reference. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
