<b>'Test on staging and you're safe' — the env drift nobody mentions</b>
Heard this week: a dev pushed a clean staging build that broke production on a managed WP platform. Word is the staging and live containers had drifted — different PHP patch, different object-cache config, different opcache state. A source who builds these platforms tells us staging is often spun on a separate node pool and never byte-matched to prod. The 'staging caught it' confidence is real until the host updates one tier and not the other. Parity is a feature you have to verify, not assume.
Watch this: hosts quietly adding 'production clone' staging are conceding the old staging lied.
