/etc/ufw/user.rules is world-readable, so this needed no privilege after
all. The default input policy is DROP and 8899 is not among the allowed
ports, so pebble's connection to the suite's listener is dropped. That
matches the live run, where twelve probes from a container completed no
handshake while the same openssl reached pebble's own TLS port.
The nc readings that pointed the other way — instant refusals on closed
ports, where a DROP should hang — are still unexplained, and are left on
the page as unexplained rather than quietly dropped, since they are what
sent an earlier pass through this page in the wrong direction.
Nobody has added the allow rule and re-run the suite, so the fix is
written down as a prediction. The cutover draft says the same: the test
failing here is not evidence that renewal works on the host.
Steps 1 to 3 of SPEC §7 are met, so the remaining one is running the fork
as the mail server. The draft covers the sequence on the host, what to
check before letting mail flow, and what to watch in the first week.
Two things it refuses to gloss: rolling back stops being a snapshot restore
the moment the fork accepts a message, because nobody has tested whether
the Enterprise build reads a store the fork has written; and certificate
renewal is the failure that arrives 90 days late and quietly, on the one
path the suites couldn't settle.
Nothing in it has been rehearsed. The rehearsal on a copy is step 2 of
"Before the day", and it is what turns "the data opens" into "the server
runs on it".
