Why:
The authority advanced its Documents gitlink and manual queue trial while this migration was under verification.
Evidence:
Read origin/main f00165e8d7 and the active Issue518 record; the Documents branch preserves its new main and approved dependency plan.
Impact:
Keep the new dependency layout, retain physical legacy Git data, adopt the merged Documents source lock and preserve manual-window progress without taking another task's window.
