+## Validated end to end (see docs/VALIDATION.md)

+- Real repos: requests, express, ripgrep, cobra, gson, Newtonsoft.Json, kubernetes (31k files; index 42 s, no OOM), vscode (14.6k files; 60 s), Wraith, classroom-archiver.
+- Fixed from that testing: large-repo memory and speed, weakening detection for Go/Java/C#, alias-import false positives, bounded `check-deps`/`verify` output, MCP map token cost, closed-pipe crashes.
+- Seeded weakening recall 12/12 on Python, JS, Rust, Go and C#; Java skips and deletions 4/4 each, loosened assertions untested.
+
 ## Known limitations (read before relying on it)
 
 - Name-based analysis without a SCIP index; dead-code precision on libraries in app mode was 1/40 on chi (use `--lib`); recall on real code is unmeasured. See docs/EVALUATION.md.
