Replication of a published study

By e2er authors

Computational reproduction of a published study from its Zenodo replication package: fetch and verify the package, plan, run it in a Docker sandbox, and compare every reported number with what the rerun produced.

Input
A Zenodo record (its DOI) and, if you have it, the published paper as PDF
Output
A reproduction report and the dossier
At the end
When any run ends, e2er builds the PDF, writes the audit trail and the structured export, and pushes to GitHub if you set that up.

Steps

  1. 1
    Fetch and verify the package
    Downloads the record keyless from Zenodo, verifies every file against Zenodo's checksum, hashes it (SHA-256) and unpacks it read-only into package/. Stages the paper the researcher supplies (paper.pdf), fingerprinted.
    check
  2. 2
    Plan the reproduction
    The replication planner maps each table and figure to the script that produces it and records the published numbers to compare against (replication_plan.json).

  3. 3
    Plan review
    The researcher reads and may edit the plan.

  4. 4
    Run the code in Docker
    The entry points run inside Docker: a pinned official image, dependencies installed first with network, then each script without network, with CPU, memory and time limits, the package read-only and outputs in a separate folder.
    check
  5. 5
    Compare every number
    The reproduction comparer levels each result (reproduced, minor differences, not reproduced, could not be run) against the targets.

  6. 6
    Reproduction check
    Re-reads every compared number from the output files and fails when the report claims one they do not hold.

  7. 7
    Report review
    The researcher reads the report.
