Review walkthrough

Explain one bound version of a code change as a causal story. Use only the evidence needed for understanding. Keep formal review and implementation separate.

Composition boundaries → process-skill-composition.md. This workflow remains complete without another skill.

Source rules → source-binding.md. Interaction choice → interaction-modes.md. Beat and finish shapes → story-format.md.

Chart-first operation

Default to causal diagrams for planning, mode transitions, and beat control.
