+-- ============================================
+-- PastPaper Master — COMP2211 problem-level taxonomy backfill
+-- Seed Date: 2026-03-24
+-- ============================================
+--
+-- Purpose:
+-- 1. Backfill coarse taxonomy for COMP2211 question rows after the paper has been
+--    processed into `paper_questions`.
+-- 2. Use the audited cover-page problem mapping as the initial analytics baseline.
+-- 3. Only fill empty taxonomy fields, so later fine-grained per-question curation
+--    can safely overwrite these defaults.
