Structural changes

Normalized root types and their transitive digests are unchanged from the preceding tag.

Verification

Extraction passed canonical-graph, root-digest, and reachable-type-digest validation, permitting the original optional surfaceOp only for historical surface events. The in-tree check reconstructs each tag from its predecessor and verifies before/after values, snapshot coverage, and bilingual machine declarations.
