ztn-check-decision
Check a pending decision or observed behaviour against the active constitution tree at 0_constitution/. Returns a verdict — aligned, violated, tradeoff, or no-match — with citations to specific principles and prose rationale. Opus-backed reasoning. Auto-appends Evidence Trail citations on every cited principle and bumps their last_applied field (L1 autonomous write — the one thing this skill modifies under 0_constitution/, never the principle body).
