Blame for mimo_v1/patch.py

"""Convert the pinned MiMo-V2.6-RL-oss Code rows to Harbor tasks and archive the Cyber rows.

    python data/mimo/patch.py --source SOURCE_DIR --output NEW_DIR

SOURCE_DIR holds the pinned code.parquet, cyber.parquet and image-mapping.jsonl
and is only read. NEW_DIR receives tasks.parquet (2,600 Code tasks whose image tag still exists and
without reward-hack residue), tasks.archive.parquet (1,000 Cyber rows, 96 Code rows with
removed images and 2 with residue, original payloads),
tasks.manifest.json and the patcher snapshot.

Code semantics follow OpenSourceCodeEnvironment (opensource_code.py and
datasets/base.py, MiMo-Agent commit 467f0a19016f0ac4d63b8d17a1f0da9ba07f232c):
capture the base ref before the agent starts, reset every path the test patch
touches to that ref, git apply the test patch, run test_command in cwd, reward 1
if and only if it exits 0, then reset the touched paths again.

    "The Code subset is published as rows of a training Parquet (problem statement, prebuilt "
    "image, hidden test patch and test command) and is graded by the MiMo-Agent environment "
    "OpenSourceCodeEnvironment, not as Harbor tasks. Each row becomes one Harbor task with its "
    "original instance ID. The instruction is the problem statement, unchanged. The environment is "
    "the published image with WORKDIR set to the row's cwd, so the repository and its dependencies "
    "are exactly the upstream ones and there is one image per task. The only addition is tmux, which "
    "the agent harness needs for its terminal: one image build step installs it from the image's own "
    "package manager when the published image has none, and does nothing otherwise. On Debian and "
    "Ubuntu that step registers root ownership for the utempter helper of libutempter0 first, "
    "because the single-user build namespace cannot assign the utmp group and the package would stay "
    "half installed (stage 3, job 997001: format-code-task-002953 could not start for that reason). "
    "The upstream reward "
    "steps are split between two verifier scripts: tests/setup.sh resets every path the test patch "
    "touches to the base commit and applies the test patch with git apply, and tests/test.sh runs "
    "the published test command in cwd, gives reward 1 if and only if it exits 0, and resets the "
    "touched paths again. A patch that cannot be reset or applied gives reward 0, as upstream. "
    "The verifier timeout is the row's verifier_timeout_sec (1800 s) and the agent timeout is the "
    "upstream default trajectory timeout (1800 s). The source has no resource or network fields, so "
    "4 CPUs, 4096 MiB and internet access are adapter defaults. Upstream records the base commit "
    "before the agent starts. Here an environment healthcheck does that before the agent runs. If "
    "that record is missing, the verifier uses the current HEAD, which differs from upstream only "
    "when an agent commits changes to files the test patch modifies. The rows contain no reference "
    "solution, so the tasks have none."
