# tests-dm.sh — NIP-17 DM interop tests for two `amy` clients.
#
# Identity A (sender) and Identity D (recipient) each live in their own
# --data-dir and share one loopback nostr-rs-relay. Tests cover:
#
#   dm-01   text round-trip (both directions)
#   dm-02   dm list surfaces prior exchange with type:text discriminator
#   dm-03   strict kind:10050 routing refuses sends to inboxless recipient
#   dm-04   --allow-fallback opts into the NIP-65 read / bootstrap chain
#   dm-05   file message reference mode round-trip (kind:15)
#   dm-06   cursor advance (subsequent no-flag `dm list` is empty)

# Wrap amy_json around either data-dir so the per-test code stays tight.
