# Participant Guide Traceability

This audit maps the hackathon guide, FAQ, and judging criteria to concrete PolyGuard implementation evidence.

## Covered Requirements

| Guide requirement | PolyGuard evidence |
| --- | --- |
| Build an OpenEnv environment with `reset`, `step`, `state`, observations, actions, rewards, and termination | `PolyGuardEnv`, `openenv.yaml`, `server/app.py`, FastAPI/OpenEnv endpoints, and OpenEnv validation |
| Use a verifiable, stateful, step-by-step task | Polypharmacy action selection over DDI, regimen risk, precision dosing, deprescribing, evidence recovery, alternatives, and new-drug decomposition |
| Provide easy, medium, and hard curriculum tasks | Scenario data in `data/scenarios/` and task presets exposed through `/env/catalog` |
| Use multiple independent reward checks and anti-hacking controls | 13 reward components, 4 primary channels, anti-cheat checks, timeout checks, candidate alignment, legality gates, and reward-range tests |
| Keep rewards numeric and bounded | `clamp_reward()` enforces `[0.001, 0.999]` rounded to 3 decimals across environment, training rewards, and API tests |
| Build dataset acquisition and preprocessing | `scripts/bootstrap_data.py`, source ingestion/build scripts, synthetic patients, retrieval corpus, scenarios, and SFT/GRPO corpora |
| Provide SFT warm start and GRPO/RLVR-style training | `scripts/train_sft_trl.py`, `scripts/train_grpo_trl.py`, TRL integration, LoRA/adapter saving, and environment-backed reward verifier |
| Use TRL/Unsloth or accepted HF TRL path | Current artifacts use `trl_transformers`; Unsloth is wired as an optional acceleration path and is used when available |
| Run full remote training when local GPU/Ollama is unavailable | `scripts/deploy_training_space.py` deploys private HF training Spaces with massive corpus build, Qwen sweeps, SFT baseline, and GRPO training support; private artifact repos require auth and are not public judge links |
| Export adapters safely and test inference | `scripts/merge_adapters_safe.py` and `scripts/test_inference_postsave.py` |
| Show results with plots and reports | `docs/results/*.json`, tracked reward/process/legal/success/sweep plot PNGs, a 3-model SFT-baseline sweep, and a top-level environment-backed GRPO run |
| Host the environment on Hugging Face Spaces | `scripts/deploy_space_api.py`, `scripts/deploy_space.sh`, Docker runtime, `docs/results/hf_space_verification.json`, and live Space health/metadata checks |
| Include a Colab training notebook | `notebooks/09_training_loop.ipynb` |
| Link story material from README | README links the selected Hugging Face blog/story URL; publish it before final hand-in if the external URL is still 404 |

## Current Evidence Status

- Local tests, OpenEnv validation, strict acceptance, and frontend build evidence are present.
- Current tracked reports include a non-fallback SFT run, a top-level non-fallback GRPO run, post-save inference, improvement reports, anti-hacking reports, and a 3-model SFT-baseline sweep.
- The optional private remote artifact pull checks reward bounds, reward precision, missing charts, GRPO adapter paths, and the anti-hacking/overfit report. Do not describe private artifacts as public judge-facing links unless mirrored.
- The strict submission gate passes as of April 26, 2026, but it validates link presence/shape, not live HTTP status.
- The live public Space target is `TheJackBright/polyguard-openenv`; `/health` returned `{"status":"healthy"}` during this audit.

## Remaining Human-Owned External Step

Publish the story artifact at the README's Hugging Face blog URL or replace it with a YouTube/slide URL before final submission. The current blog URL returns 404 until published. After publication, run `uv run python scripts/validate_submission_links.py`.
