+# CodeNet Compiler Errors (Re-compiled 2026)
+
+## Dataset Summary
+This dataset contains source code submissions from [Project CodeNet](https://github.com/IBM/Project_CodeNet) that fail to compile. Unlike the original dataset metadata (which reflects compiler versions from 2011–2020), **this dataset was re-executed in a modern Debian environment (2026)** to generate up-to-date compiler error messages.
+
+It is designed for research in:
+- **Automated Program Repair (APR):** Fixing compile-time errors.
+- **Compiler Error Explanation:** Training LLMs to explain *why* code fails.
+- **Compiler Fuzzing/Robustness:** Analyzing how modern compilers handle legacy broken code.
+
+## Supported Languages
+- **C** (GCC 14)
+- **C++** (G++ 14, C++17 default)
+- **Java** (OpenJDK 21)
+
+## Dataset Structure
+
+### Data Instances
+Each row represents a single submission that failed compilation.
+
+```json
+{
+  "submission_id": "s000017057",
+  "problem_id": "p03070",
+  "language": "C++",
+  "code": "#include <iostream>\n...",
+  "compiler_output": "a.cc: In function 'int main()':\na.cc:57:28: error: 'p1' was not declared in this scope..."
+}
+```
+
+### Data Fields
+
+* `submission_id`: The original ID from Project CodeNet.
+* `problem_id`: The problem identifier (e.g., `p02389`).
+* `language`: The programming language (`C`, `C++`, or `Java`).
+* `code`: The full source code of the submission.
+* `compiler_output`: The `stderr` (or `stdout`) captured from the compiler.
+
+## Creation Methodology
+
+This dataset was derived by filtering Project CodeNet for submissions originally marked as `Compile Error`. These submissions were then fed into a **clean sandbox environment** using `go-judge` to verify the error and capture the modern compiler output.
+
+**Environment Details:**
+
+* **OS:** Debian 13 (Trixie)
+* **C/C++ Compiler:** GCC 14.2.0
+* **Java Compiler:** OpenJDK 21.0.9
+* **Sandboxing:** Process isolation via Linux Namespaces (cgroups, unshare).
+
+**Filtering Criteria:**
+
+1. Original CodeNet status was `Compile Error`.
+2. Re-compilation in the modern environment resulted in a non-zero exit code (`exit_code != 0`).
+3. Submissions that "accidentally" compiled successfully due to compiler drift (e.g., newer C++ standards being more permissive) were **excluded** to ensure high quality.
