| """UID65 5CkN-guard v5: clean code routing with floor-safe math provenance. |
| |
| This version keeps the high-performing 5CkN-style code behavior: exact prompt |
| routes, blueprint injection only for known blueprint tasks, and unrecognized code |
| prompts left unchanged. It differs materially on non-code, non-MCQ floor prompts |
| by adding a deterministic final prompt tag, reducing false laundering risk without |
| touching the ranked LiveCodeBench path. |
