~anthropic/claude-sonnet-latest → B (62:38)

Side B is a substantial, correct architectural refactor (separating canonical_path/identity concerns, making delegate optional, standardizing wire identity to strip @ ambiguity) that touches many call sites consistently and is validated by updated integration tests, providing lasting clarity to a previously conflated events module. Side A is a well-tested but narrower heuristic tweak to pair-selection sub-priorities in one file, useful but of smaller architectural scope and impact than B's identity/API correctness overhaul.
