Current repo truth shows that this issue is no longer part of active Phase-11 closure work.

• Phase-11 is already officially closed.
• docs/specs/phase11-verification-substrate/tasks.md places this item under WS-B Policy Track, not the completed closure critical path.

Recommended reading:

• keep this issue open
• treat it as deferred policy-track work
• do not read it as an unresolved Phase-11 closure blocker
