What Cross Check does

/cross-check – Cross-Artifact Consistency Check Across Phases

Reads phase indexes and selected detail files, checks inconsistencies **between** phases (architecture ↔ implementation, features ↔ stories, threats ↔ mitigations, etc.).

Bridges the gap between intra-phase lints (`phase-docs-lint.sh`) and gate content evaluation — finds contradictions no other skill surfaces.

**Recommendation, not a mandatory step.** Gates list `/cross-check` as an optional pre-flight check.

Argument: $ARGUM
