**Spec:** `docs/p4nr/capabilities/shared-client-deregister-isolation.md`  
**Plan:** `docs/p4nr/plans/shared-client-deregister-isolation.plan.md`  
**Date:** 2026-07-21  
**Reviewer:** p4nr-spec-reviewer (Team 2)

## Verdict: **APPROVE**

### Checklist

| Criterion | Result |
|-----------|--------|
| Root cause identified (#423/#487) | Pass |
| Fix scoped to client registry/lifecycle | Pass |
| Backwards compatible (accept node or id) | Pass |
| No new palette nodes / no TLS | Pass |
| Tests specified | Pass |
| OSS stability | Pass |

### Notes

- Do not emit `mbderegister` on partial deregister (read nodes map it to close UI).
- Safe for v5 patch/minor.

**GATE 1: APPROVE — Team 3 may implement in `src/` + `test/`.**
