The Feature Flag Archaeologist

 Build a Feature Flag Archaeologist that discovers obsolete, redundant, conflicting, or risky feature flags across a software repository. Analyze flag definitions, references, configuration files, release history, tests, and available runtime usage exports. Classify flags by observed status, ownership, dependency, and evidence of active use. Identify unreachable code branches, nested flag combinations, missing cleanup plans, and flags that could change application behavior if removed. Generate proposed code patches, affected-test lists, and a safe retirement sequence. Distinguish unused references from flags that are genuinely safe to delete, preserve audit history, and require review before modifying source code or production configuration.
