/**
 * "See how it decides" — a terminal-styled pane that surfaces REAL reasoning
 * traces from a CodeWhale session, paired with the decision each produced.
 *
 * The point is "show, don't tell": every agent claims to be aligned/trustworthy;
 * CodeWhale can prove it, because the Constitution is observable in the model's
 * reasoning (it cites "Article II", "Article V", etc. as it decides). No other
 * agent can show this because none have a hierarchy the model reasons against.
 *
 * The traces below are faithful excerpts from an actual session — not invented
 * marketing copy. Keep them honest if you edit them (see AGENTS.md Article II).
