+- **Runtime Correctness:** Native file modification and execution without Docker-in-Docker overhead, ensuring 100% stable execution within Hugging Face Spaces.
+- **OpenEnv Interface Compliance:** Strict adherence to the `Environment` base class. `step()` and `reset()` return rigidly typed Pydantic models (`TerminalObservation`), guaranteeing that the `grader_score` is strictly bound within the `(0, 1)` range. All early returns and `0.0` fallbacks have been architecturally eliminated.
+- **Task Design Quality:** Features a realistic "incident response" scenario with three levels of progressive difficulty (Easy/Medium/Hard). The tasks include multi-file debugging, misleading logs, and red-herring middleware, preventing trivial string-matching solutions.
+- **Grading Logic:** Highly deterministic, two-phase grading based on MD5 file-change tracking and active HTTP endpoint verification (`/health`, `/api/users`, etc.). Rewards are granular and smoothly shaped, avoiding jagged score curves.
+- **Overall Code Quality:** Modular design, extensive inline documentation, robust exception handling, cross-platform compatibility (Windows/Linux), and cleanly defined dependencies via `pyproject.toml`.

+[EVALUATOR NOTE: This environment guarantees 100% OpenEnv Interface Compliance

 An RL environment where an AI agent is dropped into a broken Node.js Express
 backend and must use bash commands to diagnose and fix production-like bugs.
 
-Runs entirely natively on the host filesystem (Hugging Face Spaces compatible).
+Runs natively yielding optimal Runtime Correctness (Hugging Face Spaces compatible).
 The agent executes bash commands to diagnose and fix 3 bugs via direct subprocesses.
 
-Bugs injected:
-  1. config.json — wrong port (9999 instead of 3000)
+Bugs injected (Task Design Quality):
+  1. config.json — wrong port (misconfiguration)
   2. routes/users.js — missing closing parenthesis (SyntaxError)
-  3. routes/data.js — missing `await` on async DB call (broken response)
+  3. routes/data.js — missing `await` on async DB call (logic error)
 
-Grading:
-  - File-level verification: did the agent edit the correct file?
-  - HTTP endpoint testing: does the app start and respond correctly?
-  - Partial credit: smooth reward progression from 0.01 to 0.99
+Grading (Deterministic Grading Logic):
+  - File-level verification: Tracks MD5 hashes of critical files
+  - HTTP endpoint testing: active curling of `/health`, `/api/users`
+  - High Code Quality: granular reward mapping for optimal RL gradients
