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

Side B is a substantial, coherent refactor that removes duplicated/ad-hoc identity-canonicalization logic scattered across the codebase, introduces a clear module boundary (canonical_path.rs, identity.rs) with strict validation, and makes delegate optional at the type level end-to-end (CLI, wire types, reducer, HTML) with matching tests updated across many call sites. Side A is a smaller, real bugfix (removing shared browser sentinel delegates that blocked concurrent votes) which is valuable but narrower in scope, and it actually builds on the identity model B established, making B's foundational work arguably a prerequisite for A's fix.
