April 2026 monthly summary focused on performance optimization in Rails boot sequence. Delivered a targeted improvement by deferring the initialization of the View watcher until view paths are registered, preventing an eager FileUpdateChecker construction during boot. This reduces startup time and preserves correct watcher behavior. Included tests validating the new initialization flow and ensured no regression in test coverage across workloads. Collaboration note: co-authored by AI (Pi/Claude Opus 4.7).
