- decode_packet_row no longer guards Decimal.to_float / DateTime.from_naive
with passthrough clauses — Postgrex returns Decimal for numeric and
NaiveDateTime for timestamp without time zone, so the WHERE clause
filters out the only path that could have hit the alternate branches.
- recent_packets_with_paths shifts :since to UTC before to_naive so a
caller passing a non-UTC %DateTime{} doesn't silently match the wrong
window.
- moduledoc now documents that the module raises on connection/SQL
errors and is unsafe in async contexts without a catch.
