batch	✓	Nested batches — drives history, netsplit, and multiline.
client-batchdraft	✓	Client-initiated batches — the mechanism bIRC uses to send a multiline message.
message-ids	✓	A msgid on every message — keys reactions, replies, redaction, and dedup.
server-time	✓	Server-supplied timestamps, so replayed history keeps its original time.
echo-message	✓	The server echoes your own sends — bIRC shows them once.
labeled-response	✓	Correlates a reply to the command that caused it.
standard-replies	✓	FAIL / WARN / NOTE parsed and surfaced.
