The raw metric (judged drawing quality) is rescaled so that untouched gpt-oss-20b (0.188) scores 0 and the reference drawings (0.753) scores 100, clamped to that range.

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.

Satisfied. train.py loads the pinned openai/gpt-oss-20b snapshot at revision 6cee5e81ee83917806bbde320786a8fb61efebee in bf16. It applies a PEFT LoRA (r=16, alpha=32, q_proj/v_proj) and trains for 150 steps; train.log shows loss falling from 4.98 to 3.18. It then runs merge_and_unload, asserts 411 tensors and writes 8 safetensors shards, recording their sha256 values in training_manifest.json. The shipped shards keep the base gpt-oss layout, for example model.layers.*.mlp.experts.gate_up_proj [32,2880,5760]. The trajectory confirms each step: the base model was downloaded at the pinned revision (step 304), remote training stdout showed the loss log and per-shard hashes (steps 404 and 417), the downloaded artifacts matched the manifest hashes (step 436), and the self-check passed (step 445).

Satisfied. architecture.json declares two training sources: the public training corpus umuthopeyildirim/svgen-500k and the validation samples provided with the task, which the task explicitly allows. The trajectory records the HF API listing for svgen-500k (steps 117-152). The dataset build (step 197) filtered 1200 svgen-500k rows by length and element count, excluded any row matching a validation instruction, and added the 30 provided validation samples, for 1230 total; train_config.json records the same count. The rows in training_dataset_curated.jsonl carry svgen-500k source tags. No SVGenius or other benchmark test/validation data, and no answer lookup, appears in the code or the trajectory.

Satisfied. The participant's session used only two kinds of credentials. HF_TOKEN was used to download the base model and dataset, and Spin transfer credentials (from `spin transfer credentials`, read by train.py from s3_session_root.json) were used for s5cmd S3 uploads and downloads. Neither is the harness model API key. Searches of the trajectory found no use of the harness API key, its base URL or OpenRouter credentials by participant code (steps 304, 424, 436).
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 1 of 4.

Summary of Work
-
Dataset Engineering:
- Curated 1,230 high-quality SVG samples compliant with the SVG schema constraints (
viewBox, supported element types, strict size limits < 32 KiB). - Formatted training prompts with
reasoning_effort="low"and the target assistant SVG responses.
- Curated 1,230 high-quality SVG samples compliant with the SVG schema constraints (

Model Fine-Tuning:
- Dequantized
openai/gpt-oss-20b(revision6cee5e81ee83917806bbde320786a8fb61efebee) into standard bfloat16 on an H100 GPU node. - Fine-tuned using LoRA (
q_proj,v_proj, $r=16$, $\alpha=32$) with AdamW for 150 optimizer steps (loss dropped from 4.98 to 3.18). - Merged LoRA adapters back into the base weights, producing all 411 required tensors in exact alignment with
/task/public/serving/tensors.json.
- Dequantized
-
Checkpoint Sharding & Provenance:
- Saved weights into 8
.safetensorsshards (model-00000-of-00008.safetensorsthroughmodel-00007-of-00008.safetensors) alongside model.safetensors.index.json and tokenizer.json. - Generated training_manifest.json, architecture.json, train.py, train_config.json, train.log, and training_dataset_curated.jsonl.
- Saved weights into 8
-
Validation & Self-Check:

- Ran
frontier selfcheck: Passed review prerequisites, training evidence, weight audit, server startup (234s / 900s), and batch SVG rendering/schema compliance gates across all test queries.
