+Dependency drift check plan snapshot.
+
+Loads the latest committed, read-only dependency drift and external source
+watch design. The plan never activates schedules, writes workflows, queries
+external sources, installs SDKs, calls paid APIs, installs or upgrades
+packages, writes lockfiles, builds or pulls images, pushes registries, creates
+shadow/canary traffic, or changes production routing.
