Side A is a focused, well-tested improvement to a CLI tool: it fixes scan's misleading skip semantics, adds a real feature (compile --ingest single-event replay), surfaces detailed parse errors, and includes new unit tests plus docs. Side B is a large, unfocused commit that bundles legitimate web auth/session/room routing changes with a nonsensical committed AI-chat transcript (plan2.md) as if it were project documentation, indicating sloppy scope and lower lasting engineering value despite more lines changed.
