The previous commit called the bridge open on the strength of one nc run.
A later openssl s_client against the same closed port hung for its whole
timeout instead of reporting the refusal nc had just seen. Repeating the nc
test from a second image, with a control port and two closed ports, agreed
with the first: immediate refusal, which is not what a DROP looks like. The
openssl behavior is still unexplained, so the claim now carries what was
measured and the anomaly beside it.
The ALPN probe is recorded as proving nothing, for the same reason: it
hangs against a port with nothing behind it, so its silence during a
renewal says nothing about acme-tls/1.
Pebble's log is untouched by any of this: it validates and marks the
authorizations invalid, which is what makes the old explanation wrong.
