# nothing for A" failures up front instead of as a cryptic Test 03
# timeout.
#
# Implementation:
#  - `wn keys check <npub>` calls `resolve_user_blocking` which issues
#    a targeted fetch for kinds [0, 10002, 10050, 10051] on the
#    discovery-plane relays. That's the only published side-effect
#    way to populate wn's user_relays table (no public CLI reads
#    another user's relay lists directly).
#  - After the fetch, `sqlite3` is used to SELECT from `user_relays`
#    joined against `users` + `relays`. If sqlite3 isn't installed
#    the probe degrades to "trust it, go run the tests" with a warning.

  # Per MIP-00, a KeyPackage is rotated when it's *consumed* by an incoming
  # Welcome — the init_key is effectively spent and the client must
  # publish a fresh KeyPackage to the same d-tag slot.
  #
  # Earlier revisions of this test asked the human to restart Amethyst or
  # toggle KP relays, on the assumption that either would republish a
  # fresh KP. Neither actually does in current Amethyst:
  #   - Restart: `Account.ensureMarmotKeyPackagePublished` early-returns
  #     whenever a bundle already exists on disk — no rotation.
  #   - Toggle KP relays: `Account.saveKeyPackageRelayList` re-publishes
  #     the existing kind:30443 to the new relay set, same event_id.
  #
  # So drive the real MIP-00 flow instead: have B create a one-off group
  # with A as invitee. The Welcome gift-wrap delivered to A consumes A's
  # KeyPackage, `DecryptAndIndexProcessor` sees `needsKeyPackageRotation`
  # on the ingest result, and calls `publishMarmotKeyPackages` which
  # rotates the consumed slot and publishes a new kind:30443 to the same
  # d-tag. B's `keys check` then returns a different event_id.
  #
  # Rotation fires on Welcome *receive* (decrypt), not on human accept, so
  # the operator's accept is nice-to-have for group hygiene but not on the
  # critical path for this test.
