openai/gpt-chat-latest → B (10:1)

Side B makes a substantial architectural improvement by separating path normalization into `canonical_path.rs` and identity parsing into `identity.rs`, removing identity rewriting from the reducer, enforcing strict stored-form identities without `@` in APIs, and updating ingest/auth flows to support optional delegates with validation. Side A only deletes a planning document (`plan2.md`) containing design notes and example code, without changing project behavior or implementation.
