Synthetic, and what that means

Both files are the output of the API's own generator (GET /v1/sample), saved on 2026-09-22. No person and no patient. The thresholds sit near 55 % and 80 % of the exercise period because the generator placed them there, and the LT and RCP fields in the file record that placement. They show the pipeline working; they are not validation data and say nothing about accuracy.
