Mana Foil
Magic: The Gathering Commander deck builder, live at manafoil.com. I run the codebase audit and reliability workstream; Kalen Templeton is the primary engineer.
Mana Foil builds and suggests Commander decks from a player’s own collection or the whole card pool, under a price limit, with a rule-based and co-occurrence suggestion engine and a nightly data pipeline. Kalen Templeton built it. My workstream is the read-only codebase audit and its remediation: a findings board where every item was independently re-derived by an adversarial verification pass before it landed, re-verified against each new head, and closed only by a merged pull request. The migration-parity health checks on the record came out of that board.
