Writing tests for the multi-mailbox and key-log work turned up three
things, two of them in code committed earlier today.
**The "this relay serves a log" flag was global.** So was the head pin.
Signing in to a second relay that keeps no log would have been read as
the FIRST one going quiet — a fork warning against an honest deployment,
and every contact on it unreachable. The pin was worse: a second relay's
head checked against the first relay's root cannot reconcile, so the
same outcome arrived by a different route. Both are now keyed by relay
host. Pin reads fall back to the old global entry, so a phone already
holding one keeps it rather than starting trust-on-first-use again.
**A dead home relay hid every other mailbox.** `poll` read the
signed-in relay first and let its failure propagate, which is precisely
the situation several mailboxes exist to survive, defeated by an
unguarded call. But swallowing it outright broke a property that was
already tested and matters: a failed poll must not be reported as an
empty inbox, because "no new messages" and "could not reach the server"
are different things the app says different words for. Both hold now —
every mailbox is read, and the failure is raised only if NOTHING could
be read. A home that is down while a backup answers is a partial success
whose mail is returned rather than thrown away with the error.
**A relay is named in the record and dialled by URL, and those are two
questions.** The hostname is inside the signature so it can carry no
scheme and no port; how this device reaches that host is separate and
now stored beside it. That is the production shape as well as what lets
these paths be tested at all.
New: 12 tests for the address and home record (including that a relay
serving a shortened or lengthened list is caught by arithmetic), 7 for
multi-mailbox reading, 10 for sending to an address, 10 for adding and
dropping a mailbox, 5 for the control flag. A fixture that let a mock
relay forget a record it had stored is fixed too — it made every publish
after it reuse serial 1, which a real relay refuses as a rollback.
Verified against a live relay: 243 client tests.
