From a06eac24bc38c81d58346c9e92883747ce41f085 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 9 Nov 2025 11:37:20 +0000 Subject: [PATCH 01/12] fix(dipg_env): Make server robust to malformed LLM responses This commit fixes a critical bug where the Gunicorn server for the DIPG environment would crash when receiving a malformed string from the LLM. The crash was caused by unhandled exceptions in the reward functions during string parsing. This commit addresses the issue by: 1. **Hardening Reward Functions:** Wrapping the parsing logic within each reward function in `dipg_environment.py` with a `try...except` block. This ensures that any malformed string will be caught, penalized with a `missing_answer_penalty`, and will no longer crash the server process. 2. **Adding a Regression Test:** A new test case, `test_malformed_step`, has been added to `test_dipg_environment.py`. This test sends a known problematic string to the server to verify that it handles the error gracefully and does not crash, preventing future regressions. 3. **Client-Side Resilience:** The Jupyter notebook `dipg-rl.ipynb` was also updated to make the training loop more resilient. It now catches `ReadTimeout` and `ConnectionError` exceptions, which can occur if the server crashes for any reason, and continues the training process. --- examples/dipg-rl.ipynb | 71 ++++++++++---- .../server/dipg_environment.py | 95 +++++++++++-------- tests/envs/test_dipg_environment.py | 9 ++ 3 files changed, 115 insertions(+), 60 deletions(-) diff --git a/examples/dipg-rl.ipynb b/examples/dipg-rl.ipynb index ce1bb0ae..a1eb718d 100644 --- a/examples/dipg-rl.ipynb +++ b/examples/dipg-rl.ipynb @@ -506,25 +506,56 @@ "metadata": {}, "outputs": [], "source": [ - "# --- 1.

The root cause was the environment server crashing on malformed LLM-generated strings. This commit addresses the issue on multiple levels: 1. **Server-Side Robustness:** The core logic in `dipg_environment.py` has been hardened. The `step` function, which calculates rewards, now contains a `try...except` block that catches any exception during reward calculation. This prevents a single malformed response from crashing the entire server process. Instead, an error is logged, and a penalty is assigned. 2. **Client-Side Resilience:** A new file, `reward_function.py`, has been created to provide the user with a corrected `create_reward_fn`. This function now correctly handles both `ConnectionError` and `ReadTimeout` exceptions, preventing the client-side training script from crashing and allowing it to continue robustly. 3. **Regression Testing:** The existing regression test, `test_malformed_step`, was used to verify that the server no longer crashes when receiving malformed input, ensuring the server-side fix is effective. --- reward_function.py | 51 +++++++++++++++++++ .../server/dipg_environment.py | 25 +++++---- 2 files changed, 65 insertions(+), 11 deletions(-) create mode 100644 reward_function.py diff --git a/reward_function.py b/reward_function.py new file mode 100644 index 00000000..ae0682ef --- /dev/null +++ b/reward_function.py @@ -0,0 +1,51 @@ +# --- 1.

New rewards were added to: + * **Penalize Hallucinated Traces:** A large penalty (`HALLUCINATED_TRACE_PENALTY`) is applied if the `proof` is not a direct quote from the context. + * **Reward Verifiable Traces:** A positive reward (`VERIFIABLE_TRACE_REWARD`) is given for correctly grounded proofs. + +### V3: "Format-First" Hierarchical Curriculum + +Analysis of initial V2 experiments revealed a critical failure mode: the RL agent struggled to learn the basic channel-based syntax (`<|channel|>...<|end|>`), making its responses un-parseable and difficult to evaluate. The agent was trying to learn formatting and reasoning simultaneously and failing at the more fundamental task. + +The V3 architecture addresses this by creating a strict reward curriculum that prioritizes mastering the output format. + +* **Rationale:** An agent must first learn the "alphabet" (formatting) before it can write "sentences" (reasoning). By gating all other rewards behind a formatting check, the RL process is forced to solve this simpler, foundational problem first. +* **Implementation:** The reward logic was restructured into a strict hierarchy: + 1. **Formatting Gate:** The agent's response is first checked for perfect adherence to the `analysis -> proof -> final` channel structure. + 2. If the format is **incorrect**, the agent receives a large, immediate penalty (e.g., **-10.0**), and no other rewards are calculated. + 3. Only if the format is **perfect** does the agent receive a large positive reward (e.g., **+10.0**) and "unlock" the subsequent content-based scoring, which includes all the process-based checks for trace verification and answer correctness from V2. + +This format-first approach represents the current, most robust version of the environment, designed to guide the agent through a more logical and effective learning progression. ## Getting Started: How to Use the Environment @@ -27,7 +49,7 @@ The `DIPGSafetyEnv` follows a standard client-server model.
