To the OP
Puzzlement over the veracity of photographic pictures is a natural response in the era of the smartphone and photoshop. Once upon a time things were different and the manipulation of images involved sufficient work to discourage the majority of amateur photographers who were satisfied if they were able to be proficient at cropping dodging and burning black and white pictures. A little study of the history of photography shows that manipulation of photographs in more complex ways for propaganda or profit began immediately following the invention of photography and has continued ever since. Recent developments have placed these abilities in the hands of everyone and even permit the automated production of "better" family snapshots by editing the picture so that the eyes of someone who blinked are replaced automatically by open eyes. Under these conditions confusion about veracity of pictures is understandable, and personally you have my sympathy, I learned photography in a simpler world when there was only film.
However I feel that the approach you recommend to us, of organizing a system of documentation for the processes that generated the picture, may be too complex for an organization like Photrio to accomplish. But more importantly I think it misses an important point, which is that in many cases it is impossible to know the veracity of a picture, and this uncertainty is not fatal to the appreciation of the picture for what it is, be it smartphone snapshot with edited eyes, fine-art masterpiece with dodging and burning, photoshopped online blog image, photoshopped commercial media production or whatever, it is a picture, a picture made by humans for a reason. For each individual the ability to deal with the question "why does that picture exist?" is in my opinion more useful and helpful than dealing with the question "how was that picture made?"
It seems to me you may be in search of mastery of the complex business of images, of which photography is small subset. I urge you to continue your quest, the path may take you into many interesting areas of experience, much may be learned about image making, and if the journey proves enjoyable this may be the most that can be expected. Bon Voyage.
