# Regression coverage for the Bitcoin "Receive" flow. Receive addresses come
# from LND's hot wallet via the `lnd.newaddress` RPC, so this exercises the
# exact path that broke on the fleet:
#   - .116: LND REST published on the wrong host port (8080 vs the manifest's
#           18080) -> connection refused -> receive failed with the generic
#           "Operation failed. Check server logs." message.
#   - .228: the same family surfaced to the UI as a *false* "wallet is locked".
#
# These tests run on the archy host (they shell into podman / curl localhost).
#
# Tiers: read-only only — generating a receive address is non-destructive.
