Generate a buyer-specific DM, email, and PayPal note from non-sensitive context, then route a fitting buyer through the one-copy order packet before the exact $5 PayPal handoff. Use it only for a relevant buyer, not unsolicited spam.
Local-only fields. Share links include field values in the URL, so do not enter customer names, phone numbers, email addresses, street addresses, PayPal IDs, invoice IDs, or transaction IDs.
A buyer or assistant can run this without cloning the repo, verify the release, and then use the PayPal URL. This is checkout proof only; payment is not proven until seller-side evidence or PAYPAL_PAYMENT_VERIFIED=true exists.
