N Whys

Run only when explicitly invoked. Analyze the supplied question without inspecting a repository or acting on the result.

Accept an explicit positive depth n. If the user invokes $n-whys without a depth, ask for one or use 5 only when they explicitly request the conventional five-whys preset.

For each level:

1. Restate the current claim precisely.
2. Ask why it holds at the next explanatory layer.
3. Answer with one defensible link and name any shift between causal, historical, functional, motivational, or conceptual explanation.
4. Preserve uncertainty and branching rather than inventing a single root.
