The Sttattus Tax.
A cross-pillar discount fabric. Your tier and your verified rank set what you pay at every partner in the Sttattus marketplace.
Discounts Compound With Rank
The Sttattus Tax is the engine that turns your Score into dollars. It is not a coupon, a points programme, or a loyalty tier. It is a deterministic rule engine that reads your tier, your partner context, and the active rule set, and returns a precise discount in basis points.
Every checkout the Sttattus marketplace surfaces — Vault Circles, Dominion Lounges, Apex clinics, Lexicon tutors, Atlas salons — runs the same engine. The number you see on your statement is the same number empire_engine returned in production.
Glass-Box Pricing
Every applied rule is named in the response. A 25% discount on a salon booking surfaces the exact rule that produced it ("Sovereign tier · Atlas salon, restaurant partner ABC"), the basis points, and the description. The Sttattus Tax statement on your dashboard reads as a ledger, not a balance.
There is no hidden math because there is no hidden math.

Partner Specificity
Generic rules apply to everyone at a tier; partner-specific rules apply at one partner only. When both could apply, the larger discount wins — the engine always selects the best rule for the member.
Partners cannot suppress better rules. The fabric is on the member's side by default.
