602 + * Whether to accept a payment that presented no per-invoice access token,
603 + * because the Easy Invoice Pro build installed alongside cannot send one.
604 + *
605 + * Why this exists
606 + * ---------------
607 + * Pro's Stripe and Authorize.Net scripts post to `easy_invoice_process_payment`,
608 + * which is a free-plugin endpoint, and from 2.4.0 that endpoint authorises on the
609 + * per-invoice access token. Pro only began forwarding the token in 2.3.0.
610 + *
611 + * The two plugins update through different channels — free auto-updates from
612 + * WordPress.org, Pro arrives from the licence server — so "free is newer than Pro"
613 + * is not an edge case, it is the normal state for a while after release. Without
614 + * this fallback, that pairing breaks client payments, and for Stripe it breaks them
615 + * in the worst possible way: the script confirms the charge with Stripe FIRST and
616 + * only then posts here to record it, so a refusal means the customer has paid and
617 + * the invoice still says unpaid.
618 + *
619 + * What it does and does not allow
620 + * -------------------------------
621 + * The relaxation is deliberately narrow, and is never wider than the behaviour
622 + * that already shipped in 2.3.8:
623 + *
624 + * - Only when Pro is active AND older than 2.3.0. It disappears by itself the
625 + * moment Pro is updated; there is nothing to remember to turn off.
626 + * - Only when NO token was presented at all. A request carrying a wrong or
627 + * expired token is a forgery attempt, not an old client script, and is refused.
628 + * - Only for gateways provided by Pro. The free plugin's own scripts always
629 + * forward the token, so a free gateway reaching here without one is not a
630 + * version-skew case.
631 + * - The shared `easy_invoice_payment` nonce has already been verified by the
632 + * caller before this is consulted.
633 + * - `getPaymentInstructions()` does NOT use this. That is the information
634 + * disclosure path and stays fully gated regardless of Pro's version.
635 + *
636 + * Site owners who would rather fail the payment than accept the older
637 + * authorisation can return false from
638 + * `easy_invoice_allow_legacy_pro_payment_fallback`.
