e2er's internal quality review

Six reviewer specialists each score the draft from one angle, on a scale of 0 to 10. The score in the middle is the weighted average of these scores, with the weights in the table.

Pre-registration

The design was written down and frozen before the analysis ran. The hash value is the SHA-256 of the file at that moment.

The plan files were frozen with the pre-registration; the hash value after each is the SHA-256 of the file at that moment. The pre-registration check compares the files with these hash values.

Workflow (32 steps)

The run in order, from the run's own record. The run was carried out in 3 sessions on one e2er commit. How to read it

A session is one e2er process, from a start or a resume to the next stop, and each session names the e2er version and commit its steps ran on. Each specialist step shows the model, the file it wrote and the file's hash value (SHA-256). Where the run did not record the hash value, the step says so: the last step that wrote a file shows the hash value of the file at export, and earlier steps that wrote the same file are marked as superseded. Checks that stopped a step are listed where they happened: 3 here. Steps taken by the researcher (2 here) are marked with a grey dot. Stops, pauses and failures of the run are marked with a ring, at their time.
