Three SAN entries and no wildcard is the constraint that cost something real in B-7, where oauth2-proxy had to borrow Grafana's app2 hostname because a fourth name was not available. The served chain is four deep and verifies, so fullchain.pem is configured rather than the cert.pem mistake that only breaks clients without a cached intermediate.
The forced renewal and the reload behaviour could not be measured because sudo on the host asks for a password, the same silent failure first noticed in B-7. nginx reload is graceful by design, but this lab has repeatedly shown that by design is not the same as measured, so it is recorded as untested rather than assumed.
