~x-ai/grok-latest → B (1:25)

Commit A only deletes an obsolete markdown architecture brainstorm (plan2.md) with no code impact. Commit B delivers a real structural refactor: extracts canonical_path.rs and identity.rs, enforces strict naked wire identities (no @/@@, optional delegate), slims the reducer/events layer so it no longer rewrites identities, and updates CLI, APIs, HTML display, types, and tests accordingly—lasting design clarity and API consistency.
