When **Show zone overlay** is on, the iris photo on the results screen displays an interactive polar overlay. Each clock-hour sector is tappable:
– Tap any zone to open its detail panel showing all FLAT/PROT/ANW findings in that zone, the associated organ system, and a text field for **observer notes**.
– Observer notes are free-form text written by the practitioner. They are included as a named section in both the TXT report and the PDF report under “Observer Notes / Zone Overlay”.
– Notes are session-local — they are not stored in the database between sessions.
