Question: Is Kind 16 for order processing a typo for Kind 14?

[BenGWeeks]

Summary

While implementing the Gamma Markets spec, we noticed that Kind 16 (used for order processing) conflicts with NIP-18 Generic Repost. This causes clients like Amethyst to display order events as "reposts of nothing".

The Conflict

Kind	NIP Standard	Gamma Markets Spec
14	NIP-17 Chat messages	General communication
15	NIP-17 File messages	(unused)
16	NIP-18 Generic Repost	Order processing ← conflict
17	(unused)	Payment receipts

Question

Was Kind 16 intended to be Kind 14?

If all order communication used Kind 14 (with the type tag to differentiate message types), it would:

• ✓ Avoid the NIP-18 repost conflict
• ✓ Keep orders as private NIP-17 DMs (when wrapped in Gift Wrap)
• ✓ Work correctly in standard Nostr clients like Damus and Amethyst
• ✓ Use the existing type tag (1-4) to distinguish order stages

Current Behavior

When a buyer places an order using Kind 16, clients that implement NIP-18 interpret it as a "Generic Repost" with no referenced event, showing confusing UI to users.
