Whatever reads the mailbox publishes on portal.mail.received; portal
appends the note after checking the record exists in a bucket this
site has and the sender is the address the record itself holds. A
note never moves a case: a mailbox is the one door anyone may knock
on, so it cannot drive a state machine even if someone forges their
way past the checks. The desks show the conversation beside the case.
Tested: the address parser, every refusal (a stranger, no address to
compare, an empty reply, the same reply twice, an unknown contract),
and the whole path through a real JetStream - the note lands, the
state does not move, and no event is written.

Until now nothing outside a live site exercised the NATS side: the
aggregate engine was tested by in-memory replay only. This test
submits an answer, moves it from a desk through the engine, checks
that an undeclared move and an unknown record are refused, and reads
the record back from its own event log. It runs when
PORTAL_TEST_NATS_URL is set; CI starts a throwaway nats:2.14.6-alpine
with JetStream for it and tears it down. Without the variable the
test passes as skipped, so `cargo test` stays green offline.
