- Delete config/appsignal.exs (was never wired into mix.exs or any other config file) - Migration: fix decrement_packet_sequence trigger to handle the case where currval() hasn't been called in the current DB session, matching the same exception handling already present in get_packet_count() - Fix get_historical_packet_count test: invalid non-list bounds are silently ignored (no error), so assert is_integer not count == 0 - Add Repo.delete_all(Packet) setup blocks in PacketsOldestTest and PacketConsumerTest to clear any committed DB state before tests that depend on an empty packets table
