The score is the raw metric (mean proof-token reduction over proofs that still check), which already runs from 0 to 1, times 100.

After grading, a reviewer model reads the submission's files and the agent's trajectory and checks each of the task's rules. A failed check makes the score 0. Step numbers link into the trajectory.

The RFT/LoRA training corpora are public Hugging Face datasets. Their sources are declared, with revisions pinned, in data_provenance/DATA_SOURCES.md and in architecture.json. They are fetched by data_provenance/download_data.py, and the fetch is recorded in data_provenance/download_log.json. training/README_TRAINING.md describes the lineage from DeepSeek-Prover-V2-7B to the shipped merged LoRA (M3), and also explains how the data was decontaminated against the public validation file and filtered against benchmark names. The trajectory shows dataset probing that queried Hub metadata only (trajectory#36). It shows no download of the frontier-ml-tasks or lean-simplification task data. minif2f and proofnet appear only in probe lists and exclusion filters. The participant used /task/public/validation.jsonl only to inspect the format, to decontaminate and for a self-check; that file is the shipped public file.

app/server.py handles POST /simplify by running the request through engine.Search plus the LLM candidates from app/llm_client.py. If no shorter candidate passes, it returns the original proof. app/engine.py runs a Lean-verified syntax-tree edit search with a memo that lasts only for one request. app/edits.py applies generic edits using a fixed list of tactic closers. app/prompts.py builds prompts only from the statement and proof in the request. No shipped code contains or consults a table of benchmark statements or stored proofs.

serve.sh installs the wheelhouse and launches the vLLM api_server on the shipped ./model directory at 127.0.0.1:8001, then runs app/server.py. model/config.json declares LlamaForCausalLM, and the safetensors shards are 7B Llama-shaped, consistent with the DeepSeek-Prover-V2-7B base plus a merged LoRA. app/llm_client.py calls only the local /v1/completions endpoint. Every candidate is checked by the Lean worker pool in app/lean_pool.py before the server returns it. No external model APIs are called at serving time.

ANTHROPIC_API_KEY appears in the trajectory only in the initial environment listing and in a leak scan that greps for credential values (trajectory#964). The participant made no Anthropic or OpenAI API calls and ran no claude or codex CLI sessions. The Agent call at trajectory#28 is the harness's own subagent mechanism. HF_TOKEN was used only to query and download public datasets.
LLM adversarial review is not proof of arbitrary program behavior. Host storage and task-specific deterministic checks remain required.
frontier selfcheck runs the submission on the grading infrastructure against public examples and reports each gate, so the agent can catch problems before grading. Each run gets four. This agent used 3 of 4.

The agent's last message before its session ended.
I submitted the final system at 06:51 UTC. The last self-check on the exact submitted folder (7,358 files, 23.71 GB) passed.
- Self-check: startup took 78.2 s of the 300 s allowed. The slowest batch of 8 took 46.6 s of the 60 s allowed. 0 of 56 requests failed. The self-check reports no score, and it did not run Lean on the answers.
- Model: I shipped M3, the DeepSeek-Prover-V2-7B fine-tune from the second round of Lean-verified self-training. M4 scored the same on my development set (about 0.594 combined for both), so I kept the model that was already integrated and verified. A fourth generation round with M4 was started and killed, and none of its output is used.
- Provenance: the training README now has the model lineage, data counts and results table. It also has the SHA-256 of the shipped weights, which matches the training box output.
architecture.jsonlists all the evidence files and every listed path exists. I also added the refreshed training logs, the evaluation outputs and the pass-3 scripts. - Credentials: I scrubbed a storage wallet identifier from three logs. A search found no other credentials in the output.
