| """Content-driven TermiGen compatibility patches; never edit the source checkout. | |
| Source: ucsb-mlsec/terminal-bench-env, 03bddac74ada2fa344df0e93b4a3ace2034294d1. | |
| Evidence: environment-compat.md in the TermiGen audit workspace and the installed | |
| Harbor worker's _apply_dockerfile_copies / _bake_deferred_overlay. No Harbor code | |
| is changed. | |
| Rules (all detected from each archive; no task IDs or prior selections): | |
| * tmp-fixture: move only COPY fixture roots, literal initial cp/touch paths and | |
| nested /tmp WORKDIRs to /opt/task-data; rewrite references in textual task | |
| files. /tmp scratch and unrelated output paths stay unchanged. | |
| * workspace-copy: a literal file destination becomes its parent with a slash. | |
| When replay would copy a file onto itself, or COPY renames it, add a byte/mode | |
| identical alias at environment/.termigen-copy/<copy-index>/<target-basename>. | |
| Every aliased source, alias path, target, mode and hash is recorded in the | |
| output report. Original context files are retained unchanged unless a path | |
| reference inside them needs relocation. | |
| * wildcard-copy: expand existing build-context glob matches into literal COPYs. | |
| * initial-file: realize a literal RUN cp from a known, unchanged COPY payload, | |
| or an initial RUN touch, as a COPY. This retains their original bytes and | |
| avoids image /tmp mounts and workdir binds hiding the generated file. | |
| * deferred-helper: a copied script subsequently executed by RUN is also | |
| reconstructed from its exact bytes in that RUN, preserving mode, because the | |
| deferred builder does not stage COPY payloads. Only /tmp-relocated scripts | |
| are eligible; no new helper program is introduced. | |
| * env-expansion: resolve Docker ENV variable references at their declaration, | |
| using earlier ENV values and the shipped base image's PATH. The inherited | |
| PATH was read from its 10-docker2singularity.sh during pilot 948548; the bridge | |
| otherwise exports ${PATH} literally and loses mkdir/python/apt commands. | |
| Preflight leaves the WHOLE task byte-identical on missing literal COPY sources, | |
| ambiguous COPY semantics, target-root/alias collisions, or bridge-metadata COPY | |
| collisions. These decisions are reported, never silently dropped. Archives with | |
| no trigger are returned as their original compressed bytes. The per-file audit | |
| hashes content, entry type and mode and asserts that no undeclared file differs. | |
| The CLI outputs every input task. Unpatchable conditions are predictions only: | |
| the JSON report records each task ID, rule and reason while its exact input blob | |
| remains in the candidate Parquet. Archiving belongs to publish.py using stage | |
| reports. Missing verifier dependencies and NOP findings remain dataset-quality | |
| questions for the unchanged validation/publishing stages. | |
