Route X account and eligibility checks directly while regional pricing
and checkout creation share the configured proxy exit, keeping quoted
currency and amounts consistent for the customer.
A decline now cools the card×node pair and the exit's shared IP for 30
minutes first; only a card declined through two distinct nodes enters a
whole-card cooldown, and do_not_try_again blocks just that card. Card
and rotation status stay readable with no cards configured and no longer
report expired cooldowns as blocks. Links-only recovery works without a
payment card, and the recovery status endpoint reports the
payment-protection pause.
Add encrypted card pool management, persisted card and outbound rotation, and per-card decline cooldowns. Improve customer and redemption-code lookup, recovery controls, and filtering; rebuild frontend assets and refresh mock screenshots.
Give read-only eligibility checks four independent slots so payment processing no longer blocks them. Cover concurrency, slot cleanup, card rotation, and lookup behavior with tests.
