USER: Master Index 5.10.4.7 /////////////Anchor: Active thread should open with: ATAB-01 is not runtime-closed. Live bundle shows carry-forward present but V2 still hash-writes active_tab; likely incomplete/mis-scoped V2 exit-path patch unless git show 979bb1c proves source clean. Next action: read-only confirmation of 979bb1c RelationGraphV2.tsx and Wv() / activeTab() definition before any mutation.
ASSISTANT: Acknowledged: **Master Index 5.10.4.7** opens on that anchor.
Standing posture: **read-only confirmation first**. ATAB-01 remains **not runtime-closed** until `979bb1c` proves `RelationGraphV2.tsx` source clean and confirms `Wv()` / `activeTab()` no longer hash-write `active_tab`.
Boundary discipline remains retrieval-only, not implementation authority. fileciteturn0file1
