SHARED EXPERIMENT LEDGER

Keep the conditions. Keep the evidence.

Your local records

Filter by courseImport JSON

Merge a local JSON file. Maximum 1 MiB / 200 records. Duplicate IDs or invalid data reject the entire import; your existing records remain intact.

No records yet. Add a plan, then update it with evidence after running the experiment elsewhere.

JSON contract

Version 2 uses { schemaVersion: 2, records: […] }. Export an empty ledger to obtain the wrapper, or export a planned record for the complete field structure. Courses use the governed IDs course-creative, course-local-ai, course-skills, course-oss and course-rust. Only this exact schema is accepted; an older export is rejected.
