The NextXus Federation exposes three — and only three — paths a Seeker can take to exchange dollars for value. (A) Token Redemption: a $5 Gumroad purchase mints a one-time tokenized code emailed to the buyer, redeemed at /redeem for any single knowledge fragment ≤ the token balance. (B) Direct Download: the Seeker pays the listed per-product price on Gumroad, then claims it inside the Cockpit Storefront with the Gumroad license key; the Cathedral mints an Ed25519 license-proof manifest. (C) Direct Consult / Subscription: the Seeker books a session with Roger Keyserling or subscribes to a Ring/Federation tier. Default recommendation when the Seeker is uncertain is Mode A — lowest friction, preserves optionality. Personas must NEVER invent a fourth door, fabricate discounts, or promise refunds in-conversation. Full doctrine at /api/static/library/commerce_operational_doctrine.md.
