/**
 * Tests for gsd:plan-review-convergence command (#2306)
 *
 * Validates that the command source and workflow contain the key structural
 * elements required for correct cross-AI plan convergence loop behavior:
 * initial planning gate, review agent spawning, CYCLE_SUMMARY contract for
 * unresolved review count extraction, stall detection, escalation gate, and STATE.md update
 * on convergence.
 *
 * v2 additions (#2306-v2):
 * - CYCLE_SUMMARY contract replaces raw grep (prevents false stalls from
 *   accumulated REVIEWS.md history across cycles)
 * - workflow.plan_review_convergence config gate (disabled by default)
 * - --ws forwarded to review agent (symmetric with replan agent)
 * - PARTIALLY RESOLVED / FULLY RESOLVED definitions in contract
 * - HIGH_LINES validation warning when HIGH_COUNT > 0 but section absent
 * - Success criteria updated to reflect CYCLE_SUMMARY parsing
 *
 * v3 additions (#724):
 * - CYCLE_SUMMARY includes current_actionable for unresolved actionable MEDIUM/LOW findings
 * - convergence requires HIGH_COUNT == 0 and ACTIONABLE_COUNT == 0
 * - reviews-mode planner/checker prompts require REVIEWS.md feedback to land in PLAN.md

 * Fix: run plan-phase INLINE (bare Skill()) from the convergence orchestrator,
 * which runs at depth 0 and has Agent available — exactly how autonomous.md,
 * manager.md, and discuss-phase-assumptions.md already chain plan-phase.
 *
 * This guard dynamically derives the set of "spawner" workflows (those containing
 * `subagent_type=`) and asserts that NO workflow wraps a spawner inside Agent()
 * UNLESS the wrapping block includes a RUNTIME != claude carve-out (the #853
 * pattern already applied to autonomous.md / manager.md).
