Workflow checklist and results log
Choose one of four checklists, record your own observations and export a record to keep beside the output file.
A simple routine: keep the source, change one part of the workflow, reopen the output, then save the observations beside it.
Version and file checks
This is resource pack version 1.0, prepared on 7 September 2026. The verification record (JSON) documents the generated file properties. The SHA-256 list identifies the files in the pack, and the readme includes instructions and software versions.
The file checks concern these downloads. App behaviour should be recorded separately with the app version, settings and output file. The pack does not provide product performance scores.
Refer readers to the resource
When citing or linking to a download, use the relevant resource page and include “version 1.0” with any observations. This keeps the instructions and expected results alongside the file. No registration or document upload is required.
