<objective> Audit Nyquist validation coverage for a completed phase. Three states:

  • (A) VALIDATION.md exists — audit and fill gaps
  • (B) No VALIDATION.md, SUMMARY.md exists — reconstruct from artifacts
  • (C) Phase not executed — exit with guidance

Output: updated VALIDATION.md + generated test files. </objective>

<executioncontext> @~/.claude/gsd-core/workflows/validate-phase.md </executioncontext>

<context> Phase: $ARGUMENTS — optional, defaults to last completed phase. </context>

<process> Execute end-to-end. Preserve all workflow gates. </process>
