Your Software is Mission Critical

" summary

Argues that everyday systems must use mission‑critical practices: static analysis (PHPStan, Psalm) reads the PHP abstract syntax tree, continuous testing (GitHub Actions, CircleCI) runs suites on every change, and value objects plus domain design prevent real‑world errors. Gives concrete harms — autopilot failures and a customer losing a mortgage because billing was tied to a property not a person — and shows tools and tests that reduce those failures rather than vague design platitudes.
