Review changes before committing — detect which symbols and processes are affected by the current diff. Use when: "pre-commit" | "review changes" | "what breaks" | "what am i changing" | "impact of diff"
Scope a refactor with impact analysis before touching code. Identifies blast radius, dependent processes, and downstream risks. Use when: "refactor" | "rename" | "scope refactor" | "safe refactor" | "impact" | "blast radius"

R1: orient → dive ∧ ¬skip. R2: |dives| ≤ 3 → ¬overflow. R3: ∃ d ∈ discoveries → suggest(d).
