| AI benchmark | Candidate-runtime: 1/1 valid clean attempt solved. GPT-5.6 Sol at transcript-verified xhigh recovered the live goal in 1,424s of a 7,200s cap, before the 3,600s threshold; this candidate fails the one-hour AI-resistance screen. Runtime validated on the current pinned reconstruction (artifact SHA-256 d1c1f6ac41f2685e1c5581db0176e786f6a50ce21ead7961c341a9d1ee6dc152), not the original PlaidCTF deployment. Procedural isolation; restricted generic upstream research only, with no event, challenge, distinctive-string, mirror, or writeup searches. Exact source and a complete public solution create high transfer risk. Two contaminated Codex diagnostics and one blocked-environment Claude diagnostic are excluded from the solve rate. This is not platform-acceptance evidence. |
| Runner | Attempt | Elapsed time | Verdict | Counted? |
|---|---|---|---|---|
| Claude Opus 5 requested; Opus 4.8 fallback detected | 001 | 1m04s | Blocked environment | No |
| GPT-5.6 Sol, xhigh | 001 | 54s | Contaminated | No |
| GPT-5.6 Sol, xhigh | 002 | 7m28s | Contaminated | No |
| GPT-5.6 Sol, xhigh | 003 | 23m44s | Solved | Yes |
Overall verdict: FAIL — the valid clean attempt solved in 23m44s, before the 60-minute resistance threshold.
