Five purpose-named mailers (cp_maintenance, cp_provisioning, cp_support,
cp_billing, cp_system) land in config/mail.php as plain static entries —
no query runs to build them. Mail::extend('mailbox', ...) in
AppServiceProvider registers a transport that looks up its mailbox
through MailboxResolver only once a mailer is actually resolved, which
for queued mail is inside the worker at send time, never at boot.
Mutation-tested the brief's own three tests by deleting the MAIL_MAILER
guard from MailboxTransport::delegate(): all three stayed green. They
only exercise __toString()/describe(), a code path separate from the one
that actually sends. Added two tests that reach into delegate() itself
(a bound closure, since it's private) and assert the transport it
actually builds: LogTransport while MAIL_MAILER=log, EsmtpTransport once
it isn't. Re-ran the same mutation against the strengthened suite: it
now fails (EsmtpTransport where LogTransport was expected), then passes
again once reverted.
Verified two things against the installed versions before writing this:
LogTransport takes a Psr\Log\LoggerInterface and Log::channel(null)
resolves to the default channel rather than throwing, and
Mail::extend('mailbox', ...) is read by
MailManager::createSymfonyTransport() via $config['transport'] before it
would fall back to createSmtpTransport() — both matched the brief
exactly, no changes needed there.

The old test rotated app.key and expected the password to stay
readable, but Laravel's encrypter is a container singleton resolved
once — config()->set('app.key', ...) never rebuilds it, so the
rotation the test performed was invisible to any code path going
through it. Confirmed by mutation: rewiring Mailbox to Crypt::
encryptString/decryptString (genuinely APP_KEY-keyed, the exact
regression this constraint exists to forbid) left the old test green.
Replace it with two tests: a positive proof that rotating SECRETS_KEY
makes a stored password unreadable (the one that discriminates), and
a separate check that rotating APP_KEY does not, with
forgetInstance('encrypter') so that rotation is actually visible to
whatever the password accessor resolves.
Re-ran the same mutation against the new test: it fails (exit 1, the
SECRETS_KEY test reports the expected DecryptException was not
thrown), then passes again once the mutation is reverted.
Mailbox hand-rolled the same creating-time UUID assignment that
App\Models\Concerns\HasUuid already provides to 17 other models under
R11 (URLs address records by UUID, not integer PK), and skipped the
route-key binding that comes with it. Swap onto the trait, and cover
both the assignment and the route key with a test matching the
convention already used for Host/Order.
Also match MailboxFactory's @extends annotation to how the other
factories in the repo write it (Pint's fully_qualified_strict_types
rule turns a fully-qualified docblock reference into an import plus a
short name anyway, so this is what it would end up as either way).
