~anthropic/claude-sonnet-latest → B (6:4)

B fixes a concrete production bug (shared sentinel delegate blocking multi-user voting) with a targeted, well-tested change including a regression test proving two users can vote independently. A is a larger refactor (splitting identity/canonical_path modules, dropping @ from wire format) that improves clarity but is mostly reorganization/renaming without fixing a live user-facing defect, and its scope makes correctness harder to fully verify despite the added tests.
