Name refused tracks before Undo_EndBlock2, not after; tighten the route-list doc; pin the refusal memo's gate

Fixes D (handle lifetime), C (ASCII dashes), G (comment compression), I (shouldReport extracted + tested); CLAUDE.md route list corrected per A/B/H. E pushed back -- cross-module GUID plumbing is architectural, not a targeted fix.
