ReproLab

ReproLab turns a bug report into a portable local reproduction package. It stores the report, source reference, environment manifest, commands, bounded logs, Sandbox ID, and file diff.

alg repro create bug-report.md --source . --test-command "python -m pytest -q"
alg repro status REPRO_ID
alg repro export REPRO_ID --output reproduction.zip

Creation, status, diff, and export work without Docker. Running setup or test commands requires Docker because ReproLab delegates execution to the copied workspace Sandbox:

alg repro run REPRO_ID --timeout 300
alg repro diff REPRO_ID

The original source directory is never mounted into the container and is never modified by ReproLab.
