The vault's mail.password row is no longer deleted by this migration at
all, in either direction: deleting it unconditionally destroyed a real
password whenever MAIL_USERNAME was empty (nowhere to carry it to), and
even on a successful carry-over a later rollback had nothing left to fall
back to. Reproduced both against real MariaDB, along with a migrations-
table drift that crashed a retry on the mailboxes.key unique constraint —
fixed with Mailbox::firstOrNew() and a transaction around each direction.
down() now goes through the new Settings::forget() instead of a raw
delete, so it stops leaving the settings cache holding what it just
removed. A skipped .env password (SECRETS_KEY still unset) now prints an
operator-visible line instead of migrating clean and failing silently
later. Host/port that resolve to config/mail.php's own placeholder
defaults are treated as unset rather than as a real relay.
The seed migration also guards against SECRETS_KEY being unset at migrate
time (encrypting the .env password would otherwise throw and take the
whole migration down, on a fresh install as much as in the test suite),
and the four tests/Feature/Mail files written before this migration reset
the mailbox table in their beforeEach so they keep testing what they did
before mailboxes.key collided with the seeded rows.
A mutation the reviewer ran (if ($box !== null) -> if (true)) left every
test green: CloudReady hand-rolled the same null-mailbox guard as
SendsFromMailbox, but nothing exercised its null branch. Added the
missing test, then extracted the decision itself (null mailbox -> no
sender fields, no_reply -> no Reply-To) into one shared method so an
Envelope-shaped and a MailMessage-shaped consumer can no longer disagree.
Re-review of the previous fix round found the "cannot disagree" part of
finding 4 was still open. resolution() had unified the log/array/null/
mailbox decision, but inside the mailbox branch describe() returned
$box?->address unconditionally while delegate() additionally required
isConfigured() before using it. A mailbox with active=true, a real
address, and no password produced
'mailbox://support/support@clupilot.com' — reading as entirely healthy
— while send() threw. That is exactly the harm the original finding
named: the log says fine, the mail fails.
resolution() now decides "unconfigured" too, not just "which
non-delivering mode": it calls isConfigured() itself, once, and returns
that verdict alongside the box. describe() and delegate() both branch
on the SAME result again, the same way they already did for log/array/
null — a mailbox with no password now reads as
'support@clupilot.com [unconfigured]' rather than a plain address, and
the address stays visible so an operator can tell WHICH mailbox needs
fixing.
Also renamed a test the re-review flagged as promising more than it
checked: "registers a mailer per purpose without touching the database
at boot" only ever verified the config array's shape — the DB-touching
claim is a separate, already-passing test just below it
(defines every purpose mailer as a plain literal...). Renamed to
"registers a mailer for every purpose". No behaviour change.
Added a test creating a mailbox with no password and asserting the DSN
both names the address AND carries the marker, plus that send() still
throws — proving agreement, not just a matching label painted on
separately. Mutated describe()'s unconfigured branch to drop the
marker: the test failed exactly on the missing 'unconfigured' string
(DSN read as a plain, healthy-looking address again). Reverted, reran,
passes.
Full suite: 667 passed. vendor/bin/pint --test clean on both files.

The reviewer continued the mutation sweep from Task 4's own commit and
found three more unpinned lines in delegate(), plus two real behaviour
gaps, all inside the same 40-line method:
- The fingerprint refresh (the headline feature: a worker's mailer
must pick up a corrected password without a restart) had no test —
mutating its check to "delegate === null" left the suite green.
- The implicit-TLS third argument to EsmtpTransport had no test either
— mutating it to a hardcoded true left the suite green, because the
only assertion touching it was instanceof EsmtpTransport, which the
hanging variant also satisfies.
- isLogging() only ever checked for 'log', but phpunit.xml sets
MAIL_MAILER=array for the whole suite. Task 5 wires real mailables
to these mailers next; the first feature test that sends one without
Mail::fake() would have opened a real SMTP connection.
- describe() and delegate() each ran their own copy of that guard —
which is exactly how deleting it from ONLY delegate() passed the
whole suite in the first place: __toString() kept reporting "log"
from its own untouched copy.
- An unconfigured host/port (Settings::get('mail.host', '') and a
stored null port casting to 0) built a transport pointed at
smtp://:587 or silently downgraded to plaintext port 25, instead of
refusing the way a missing mailbox already does.
Fixes: replaced isLogging() with resolution(), the one place that now
decides "log, array, null-default, or a real mailbox" — describe() and
delegate() both branch on ITS result, so a guard broken in one cannot
look fine in the other. Added an explicit RuntimeException for a blank
host or non-positive port, guarded the same way as the missing-mailbox
case just above it.
Tests: added coverage for the fingerprint rebuild (reuses the same
delegate until the password actually changes, proven by object
identity), the exact DSN string for both the STARTTLS (587) and
implicit-TLS (465) cases, 'array' and unset-default both landing on a
non-delivering transport, and the blank host/bad port throwing.
Mutated each of these four in turn on the final code and confirmed:
fingerprint check removed -> the reuse test fails (same object handed
back after the password changed); TLS argument hardcoded true -> the
587 DSN test fails ('smtps://...' where 'smtp://...:587' was
expected); NON_DELIVERING narrowed back to ['log'] -> both the array
and unset-default tests fail (a real EsmtpTransport where a safe
transport was expected); host/port guards removed -> both throw
expectations fail. Reverted each, reran, all twelve tests pass again.
Replaced the two tests that reached into delegate() via Closure::bind
to check "log or SMTP" with one behavioural test: point Settings at a
closed loopback port (127.0.0.1:1, so refusal is instant and entirely
local — no DNS, no dependency on this environment's network egress
policy) and assert Log::shouldReceive('debug')->once() while sending
for real through Mail::mailer('cp_support')->raw(...). Mutated
NON_DELIVERING to drop 'log' specifically and confirmed this test
alone catches it: a real connection attempt to the closed port throws
TransportException (Connection refused) in under 300ms. Reverted,
reran, passes again.
Also: the two tests that only checked the config array's shape and a
snapshot of the resolved address promised more than they verified —
CLAUDE.md R19 names a test that recomputes the implementation as
checking nothing. Added a source-level test that the five cp_* config
entries are parenthesis-free literals (same technique
DisplayTimezoneTest/IconLayoutTest use: a property of the file, not of
one run) as the actual "no query at boot" proof, and renamed the
send-time test to what it verifies now that the fingerprint test above
covers the live-refresh claim properly.

Review of Task 4: MailboxResolver::for() only fell back on a missing
mapping or a missing row. Deactivating a mailbox — the operator's
explicit "do not use this" — left it resolvable anyway, so
MailboxTransport reached it, found isConfigured() false, and threw
instead of quietly using the next candidate the way every other
"this mailbox is unusable" case does. Worse, __toString() still
reported the deactivated address as though it were healthy.
named() now runs through a new active() filter at BOTH lookup sites —
the purpose's own mapping and the system fallback — so an inactive
system mailbox is refused exactly like a missing one, not handed out
as the last resort. A missing password stays deliberately unfiltered
here: that is a MailboxTransport concern (loud failure naming the
mailbox), not a resolver fallback trigger — silently rerouting mail
because a password hasn't been typed yet would hide the gap instead
of surfacing it.
Added two tests and mutated active() to a no-op filter to confirm they
catch it: both failed (one expected the system mailbox, got null; the
other expected null, got the inactive mailbox's full attribute dump).
Reverted, reran, both pass again.

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).
