Why: The review candidate needed current-main synchronization and a fixed account of the post-sync Backend, RDM, browser and PostgreSQL verification.
Evidence: Tool-written SELF receipts preserve failed parallel PG/SSE and browser setup attempts alongside serial PG, source-overlay, frontend and fresh-browser successes at their exact objects.
Impact: Task card only; stage 6 remains for human judgment, and stage 7, trusted Backend pin, GATE, PR, merge and production operations remain pending.
Refs: Backend d2f9b16, RDM source 98f50be, Documents amendments fb3a821 and 5783940.
