Deploy and rollback
Staging and production configured differently
A flag or variable exists in one environment and not the other, so a release passes in staging and fails in production.
Termsprotected branch (the git branch that cannot be pushed to directly and is the only source of production deploys) · CI (the pipeline that builds and tests every change before it can be merged or deployed) · staging environment (a copy of production, without customer data, where release candidates are tested) · verdict (a one-word release result (pass, pass with findings, fail) with the findings and the checklist version behind it)

Why AI-assisted code produces it
Variables are added where the feature is being built. The Replit response listed environment separation as something that had to be built in, not assumed.
After the deletion, the platform announced separate development and production databases, a planning-only mode, forced documentation checks and one-click restore.

How we detect it
Diff variable names and flags between environments on every release.
Checklist items that catch it
Environment configuration matches across staging and production
automated Diff the set of variable names and feature flags between staging and production.
The only differences are values, not names; every flag present in one exists in the other.
Dots: Starter, Growth, Scale. The item runs on every release for the plans marked.
