Open research gaps
Full French patent scans, several Gallica full-text captures, VIAF data, HathiTrust holdings, and some official European patent repositories were blocked or unstable during automated research. Those gaps should remain visible rather than filled with guesses.
The most important future work is not adding more modern commentary. It is extracting named clinical observations from La sante par les ondes, checking them against institutional records, and locating official scans for non-U.S. patents.
