November 2024 (canonical/mongodb-k8s-operator): Stabilized CI debugging workflow by implementing a temporary CI caching disablement and related artifact-prefix adjustments. Changes included: build-charm cache set to false and temporary prefixes in integration-test and release.yaml. Commit: ab4e9e7e470261fe540094b1fb0ec0052fd4878a. This work improves CI stability, speeds issue reproduction, and reduces debugging friction, with a clear revert path for when caching is re-enabled. Technologies demonstrated: CI/CD practices, YAML configuration, reversible change management, and careful change logging.
