Snag staging now aligns M1 raw cards, M2 sealed products, and M3 graded cards with the three supplied rules. It implements the documented condition factors and sales windows, equal M2 weighting, ±30% filtering, exact grader/grade matching, and M3 listing fallback without making a live Cardmarket or eBay request.

CardTrader and GCC are explicitly labelled alternative/available sources; missing closed feeds produce no quote rather than a fabricated zero. The mobile app switches M1 values as condition changes, includes exact quotes in collection totals, and permits a clearly labelled personal value for M1, M2, or M3 when evidence is insufficient.
