Why every photo carries its farm, its date and its place
A photo with no relationships is a file. A photo that knows which farm, which task and which day it belongs to is evidence.
The developer brief for this system contains a short instruction that shaped a surprising amount of it: do not simply store files without relationships.
When a farmer photographs a compost heap, the camera opens directly — no file picker, no gallery. On capture, the photo is stored with the farm it belongs to, the coordinates it was taken at, the moment it was taken, the task or diary entry it evidences, and the farmer who took it. None of that is typed. All of it is attached automatically.
That is what lets a Cluster Leader judge evidence in one view instead of opening three screens: the photo, the note, the coordinates, the time, and whether the location falls inside the recorded farm boundary. Approving it writes the practice into the farm’s history and moves the farmer’s progress indicators.
It is also why farmers can hide a photo but never delete one. The record and the file both survive, because a certification file assembled two years later is only as good as the evidence still standing behind it.
