Recommendation regression benchmark

Seven complete stock decks and five constraint scenarios run against a frozen October 7, 2026 snapshot of 503 real Scryfall cards. This page is regenerated with the engine during a production build. It checks supported constraints and functions; it does not establish win rates or human approval of every suggestion.

The benchmark candidate pool is broader than the live search pool. Live prices, legality, candidates, and exact suggestions can differ. Human review should check lost abilities, tribal bodies, casting restrictions, and the intended table.

Review the result in play

Keep the stock baseline and edited version, record which abilities or timings mattered, and report an unhelpful package through the result controls. Automated role matching is not a substitute for that review.
