By the end of May, WordPress had become an engineerable system instead of just a server

Situation

At the beginning of the month, WordPress modernization still depended heavily on knowing the production server. Plugins could be updated and files changed, but every significant modification raised the same question: where and how can we reproduce this safely before touching live production?

Approach

Docker Compose, the custom image, WP-CLI, runtime limits, proxy handling, URL normalization, permissions and secret management together formed a development platform. None of those commits was especially flashy on its own, but each moved another implicit server assumption into a versioned, repeatable system.

Outcome

By June, WordPress core, theme and plugin upgrades could be rehearsed in a controlled environment. Production no longer had to serve as an experimental lab, and upgrade risk became much easier to measure. The system finally had the minimum engineering layer it had been missing.
