Used before a large refactor or on a codebase that grew fast, once syntactic copy-paste duplicates are already handled.

Copy-paste detectors match text, so they miss the kind of duplication that piles up in agent-written code: two functions with unrelated names and unrelated implementations that mean the same thing. The run starts with a script that extracts a catalogue of every function, sorts them into domains with a cheap model, then sends each domain to a stronger model that only has to compare a handful of candidates. The output is a report a human still has to sign off on before anything is consolidated.
