| # T3 Initial GRPO Run |
|
|
| Private archival dataset for the canonical initial T3 GRPO experiment: |
| `full_censored_grpo_20260723_a`. |
|
|
| ## Experiment identity |
|
|
| - Warm start: `qwen36-35b-su-t3-practice-step160` |
| - Coding agent: `claude-opus-4-6` |
| - Training pool: 192 tasks across 23 apps |
| - Fixed held-out cohort: 16 tasks |
| - Batch size: 32 |
| - GRPO group size: 8 |
| - Maximum sequence length: 131,072 tokens |
| - Completed training length: 32 optimizer steps |
| - Complete model checkpoints produced at the end of the run: steps 30 and 32 |
|
|
| This is the corrected run with enforced censored-rollout filtering, the final |
| thinking-mode contract, bounded policy lag, deterministic curriculum order, |
| and the canonical held-out evaluation cohort. |

| - Per-session SU/CA histories, final repositories, traces, and the Bedrock |
| request/cost ledger. |
| - `prime_training_artifacts_full_censored_grpo_20260723_a.tar.zst` |
| - Prime-RL rollout batches, configs, logs, lightweight control/checkpoint |
| state, maintenance evidence, and offline W&B data. |
| - `canonical_evals_full_censored_grpo_20260723_a.tar.zst` |
| - Canonical held-out evaluations for the raw base, SFT step 160, and GRPO |
| steps 10, 20, 30, and 32, plus the aligned-thinking gates. |
| - `timeout_canaries_full_censored_grpo_20260723_a.tar.zst` |
| - Timeout/cancellation canary runs used to validate censoring behavior. |
| - `replays_full_censored_grpo_20260723_a.tar.zst` |

| - `launcher_state_full_censored_grpo_20260723_a.tar.zst` |
| - The launcher state and run logs from |
| `/home/aarav/.nova_full_runs/full_censored_grpo_20260723_a`. |
| - `t3_task_dataset.tar.zst` |
| - The exact `/data/aarav/dataset/T3` task data referenced by the run. |
| - `SOURCE_INVENTORY.txt` |
| - Source paths, raw byte counts, exclusions, and file counts. |
| - `SHA256SUMS` |
| - Checksums for every archive. |
| |
| ## Deliberate exclusions |
|
|
| This dataset intentionally excludes reproducible or separately archived model |
| state: |
|
|
| - Prime full checkpoints at steps 30 and 32 |
| - exported model weights at steps 30 and 32 |
| - Prime broadcast snapshots |
| - temporary eval-model exports for steps 10 and 20 |
|
|
| Model weights belong in Hugging Face model repos, while this dataset contains |
| the experiment evidence needed to reconstruct and audit training and |
| evaluation. No artifacts from the abandoned `full_opus_20260717` run are |
| included. |
|
|
| ## Restore |
|
|
| Verify first: |
|
|
| ```bash |
| sha256sum -c SHA256SUMS |
| ``` |
|
|
| Extract an archive: |
|
|
| ```bash |
| tar --use-compress-program=unzstd -xf ARCHIVE.tar.zst |
| ``` |
|
|
| The tar members retain the original `full_censored_grpo_20260723_a` directory |
| name so that provenance remains unambiguous while the dataset repo uses the |
| friendlier name `t3_initial_grpo_run`. |
