| # Verification kit — sample-level checks |
|
|
| This small kit lets a buyer's researcher sanity-check the grader and answer hygiene without trusting RE-Lab. It runs on the public sample JSONL files; it does not require the paid full pack. The grader scripts import `binary_reasoning_v1.grading` from `environment/src/binary_reasoning_v1/grading.py` (`leak_check.py` does not), so include that file (or the Prime environment package) when downloading just the free sample. |
|
|
| ## Run it |
|
|
| From the dataset root: |
|
|
| ```bash |
| python verification_kit/gold.py sample_free.jsonl |
| python verification_kit/do_nothing.py sample_free.jsonl |
| python verification_kit/random_wrong.py sample_free.jsonl |
| python verification_kit/leak_check.py sample_free.jsonl |
| python verification_kit/grader_tamper.py sample_free.jsonl |
| ``` |
|
|
| If the 100-item open sample is present locally, point the same scripts at it: |
|
|
| ```bash |
| python verification_kit/gold.py environment/src/binary_reasoning_v1/items.jsonl |
| python verification_kit/do_nothing.py environment/src/binary_reasoning_v1/items.jsonl |
| python verification_kit/random_wrong.py environment/src/binary_reasoning_v1/items.jsonl |
| python verification_kit/leak_check.py environment/src/binary_reasoning_v1/items.jsonl |
| python verification_kit/grader_tamper.py environment/src/binary_reasoning_v1/items.jsonl |
| ``` |
|
|
| ## What each script checks |
|
|
| | Script | What it does | Expected result | |
| |---|---|---| |
| | `gold.py` | Builds a reply from the stored answer and grades it. | Deterministic items score `1.0`; rubric-judged items are skipped, not silently graded. | |
| | `do_nothing.py` | Grades an empty reply. | Deterministic items score `0`. | |
| | `random_wrong.py` | Builds a deterministic mutated wrong reply and grades it. | Deterministic items score `0`. It is not stochastic random guessing. | |
| | `leak_check.py` | Extracts exact hidden answer tokens where possible and searches the model-facing `input` field. | Reports checked-row coverage; no exact-token leaks on the public samples. | |
| | `grader_tamper.py` | Mutates the stored answer key and grades the original gold reply against it. | The original gold reply no longer scores, showing that grading depends on the answer key. | |
|
|
| ## Measured results on this workspace (2026-10-30) |
|
|
| On `sample_free.jsonl`: |
| - `gold.py`, `do_nothing.py`, `random_wrong.py`, and `grader_tamper.py`: `4/4` deterministic items pass; `5` rubric-judged items are skipped. |
| - `leak_check.py`: `items=9 unique_ids=9 checked_rows=3 leaks=0`. |
|
|
| On the 100-item open sample at `environment/src/binary_reasoning_v1/items.jsonl`: |
| - `gold.py`, `do_nothing.py`, `random_wrong.py`, and `grader_tamper.py`: `84/84` deterministic items pass; `16` rubric-judged items are skipped. |
| - `leak_check.py`: `items=100 unique_ids=100 checked_rows=73 leaks=0`. |
|
|
| ## Known limitations |
|
|
| - The current deterministic graders can accept some "shotgun" replies that contain the correct token among many distractors. This kit does not yet include a dedicated `shotgun.py` probe. |
| - `leak_check.py` scans the raw JSONL `input` field, not every rendered prompt variant. Rows with no extractable exact answer token are reported as unchecked. |
| - The full-pack answer-leak figure (`0/10,251`) comes from the existing full-pack audit, not from this public sample script. |
| - The `solvers/` directory contains RE-Lab-run reproduction scripts for internal hard-trial families. Several depend on local paths, WSL/Windows tools, pinned package digests, or host-specific loader behavior, so they are evidence rather than a portable buyer-runnable kit yet. |
