+# CrossCodeEval
+
+The pinned TaskTrove release contains **7,763 cross-file code-completion tasks** across C#, Java, Python and TypeScript. All existing context, scoring and instruction repairs are preserved.
+
+- **Docker images: 3 distinct definitions originally; 3 retained, provided as 3 shared cached images.** No image consolidation was needed.
+- **Tasks: 6,710 kept, all 6,710 changed; 0 unchanged and 1,053 excluded.**
+
+| Language | Original | Kept and changed | Excluded |
+| --- | ---: | ---: | ---: |
+| C# | 1,768 | 1,353 | 415 |
+| Java | 2,139 | 1,895 | 244 |
+| Python | 500 | 432 | 68 |
+| TypeScript | 3,356 | 3,030 | 326 |
+
+## Stage 3: Build/setup
+
+- **6,710 tasks patched:** pinned `pytest==9.1.1` and `pytest-timeout==2.4.0` in their image definitions for reproducible installation.
+- **0 tasks excluded.** All 6,710 environments built and started successfully.
+
+## Stage 4: Reference solution reward 1
+
+- **6,710 tasks patched:** added a reference solution that writes the benchmark's expected completion, allowing the correct answer to be checked automatically.
+- **0 tasks excluded.** All 6,710 reference solutions scored 1.
+
+## Stage 5: No-op reward 0
+
+- **6,710 tasks patched:** replaced the original grading scripts with a scorer that compares the completed statement after normalizing comments and whitespace. This removes rewards for incomplete prefix matches and avoids rejecting correct Java completions solely for indentation.
+- **0 tasks excluded.** All 6,710 no-op attempts scored 0.
+
+The stage repair counts overlap; they refer to the same 6,710 retained tasks.
+
+## Task-quality changes retained
+
+- **6,710 tasks:** restored the benchmark's retrieved excerpts from related files, excluding excerpts from the target file or containing the answer.
+- **6,710 tasks:** preserved the corrected instructions, context-file guidance and automatic timeout/anti-cheating sentence.
+- **1,043 tasks excluded:** required names could not be inferred from the prompt, retrieved context or known library names.
+- **10 tasks excluded:** the scored completion contained no variable, function, class or other code name.
+
+## Images and validation
+
+Download the three cached Apptainer images from [images/](https://huggingface.co/datasets/FWeindel/validated-tasks/tree/main/crosscodeeval_environment-reliable/images). The Parquet includes pinned image references for automatic download and checksum verification.
+
+Task payloads are unchanged from the [previous release](https://huggingface.co/datasets/FWeindel/validated-tasks/discussions/14); its recorded stages 1, 3, 4 and 5 remain applicable. [Teacher results](https://huggingface.co/datasets/FWeindel/validated-tasks/discussions/6) are available separately.
