# Difficulty check against a frontier model (Claude Opus 5.5)

This file records measured frontier-model difficulty checks for RE-Lab binary-reverse-engineering tasks. It is not a leaderboard and not a calibrated pass@k band table unless explicitly labelled as one.

## Method and conditions
- Agentic screens used shell/file tools (`objdump`, `strings`, `xxd`, Python, Docker or direct execution where available), with a 30-minute limit.
- Host runs are non-isolated upper bounds: tools were available, but the model was not run inside a sealed buyer sandbox.
- Single-shot checks had no tools unless stated.
- Times are wall-clock minutes from the measured run. Partial scores are shown when the grader records partial credit.
- This report does not claim that a task family is "frontier-hard" unless it has a measured 2-30% band on the target model class.

## Results

| Task set | Model / mode | Result | Time or score | Interpretation |
|---|---:|---|---:|---|
| Public agentic flag-hunt environments, 29 Harbor environments | Claude Opus 5.5 with shell/file tools | 29/29 environments solved, 145/145 attempts | median 44 s | Practice/warm-up level for a tool-using frontier model. |
| Public single-shot identification sample, n=12 | Claude Opus 5.5, no tools requested | 7/12 correct | about 58% | Useful sanity check, not an RL band and not comparable to the agentic set. |
| Spot check of the earlier trial pack (legacy ids brv-hrd-*), 20 sampled items from 10 of 19 families | Claude Opus 5.5 with shell/file tools | 40/40 attempts in corrected rerun | `40/40 attempts` | Agentic Opus 5.5 solved the sampled tasks from the earlier trial pack (40/40), so as shipped they are practice for frontier models. |

## What this means
- The current public agentic pack is solvable by a tool-using frontier model; it is practice/warm-up material, not proof of a 2-30% RL band.
- The prior "hard" label was measured and did not survive agentic testing; it is no longer sold as hard-tier material without new calibration.
- Private task families are calibrated on fresh, never-published instances across several models (open-weight and Claude sizes); results and method are shared privately with prospective buyers.
