 - Active concurrent foreach correction: replace item-body `END` routes with
  canonical back-edges to the owning foreach. The approved semantics are in the
  [`foreach back-edge design`](superpowers/specs/2026-09-04-foreach-back-edge-design.md).
+  This slice also makes foreach control regions fail-closed, rejects unreachable
+  workflow nodes, and gives repeated visits to one foreach node distinct
+  persisted activation identities.
 - After that correction, reuse the foreach barrier/lineage machinery for
  fork/gather. The proposed control semantics are recorded in
  [`ADR-0006`](adr/0006-explicit-fork-and-topology-driven-gather.md).
