ROOT CAUSE of "alert fires but no e-mail", third and final layer: the
metrics poller (clusev:poll-metrics, a long-lived supervisor process) is
what queues alert mail — and Laravel bakes the DEFAULT MAILER NAME into a
mailable at Mail::to()->queue() time. A poller that booted before SMTP
was configured bakes `log` into every alert e-mail forever; the worker
then faithfully "sends" them into laravel.log no matter how correct its
own config is. This is why manual test sends (fresh processes → smtp)
arrived while real alert mails (poller → log) never did.
Fix: extract the SMTP-settings application into App\Support\MailSettings
(::apply(), now with Mail::purge on change so long-lived processes
rebuild the transport) and call it from all three process shapes:
- web requests → AppServiceProvider::boot()
- queue worker → Queue::before
- poller/loops → AlertNotifier::notify() right before queueing,
so the CURRENT mailer name is baked in.
Also: enterprise HTML alert e-mail (frontend-design). Dark Tactical
Terminal card — signal rail + status pill (red ALARM / green BEHOBEN),
rule headline, mono terminal readout (server/metric/value/threshold),
bulletproof dashboard CTA, CID-embedded logo (no external assets; renders
in Gmail/Outlook with images blocked), full de/en, plain-text part kept
as fallback. Offline rules render state text (offline/back online)
instead of a bare 0/1.
Verified: app restarted (poller reloaded), synchronous + queued sends to
the admin both deliver over real SMTP (476ms send, no new log-mailer
entries). 750 tests.
