 | Date | Reflection | Trigger | Action | Detail |
 |---|---|---|---|---|
+| 2026-09-16 | UI elements describe API requirements | User corrected drift from interface research into report-scheduler/SFTP and repeated browser requests | Map business criteria/fields to real operations; do not treat XML input format as a native-download-only restriction or switch workflows implicitly | [Case](cases/2026-09-16-ui-elements-are-api-requirements.md) |
 | 2026-08-11 | Technical surfaces need explicit entry controls | The user corrected the Daily table because inspecting a business row unexpectedly opened a dense technical log | Keep ordinary rows informational, place technical utilities behind named controls, and remove interaction styling/semantics with the handler | [Case](cases/2026-08-11-technical-surfaces-need-explicit-entry-controls.md) |
 | 2026-07-31 | Formatting is not business state | A yellow final Booking row was initially at risk of being interpreted as cancellation | Make cancellation text-based, preserve formatting as non-authoritative and keep a real-style regression | [Case](cases/2026-07-31-formatting-is-not-business-state.md) |
 | 2026-07-30 | Coordinate hot static assets with the long-lived backend | Login static files activated before backend restart; later launchd ownership also hit macOS Desktop privacy | Feature-detect mixed versions, gate restart on all secrets, use a secret-free launcher and a desktop-authorized supervisor until deployment leaves Desktop | [Case](cases/2026-07-30-coordinate-hot-static-and-long-lived-backend.md) |
