Trace the real problem across layers. Test assumptions, narrow uncertainty, and find the leverage point.
Turn the useful answer into working software, infrastructure, tooling, or a repaired workflow.
Leave behind an operable system, clear decisions, and enough context for the next change to be straightforward.
Working principle
Legacy technology can be understood, stabilized, and improved. Progress starts with permission to change what the investigation proves should change.
