An operational checklist for Bitcoin merchants who want to receive sales to a watch-only setup and sign spending transactions elsewhere. Differentiates transaction construction, offline signing, verification and broadcast so sellers don't mistake an unsigned proposal for a payment.

The unlock contains a dated, source-backed procedure and a reusable worksheet, with important unknowns identified. No live implementation or exclusive files are claimed.
