I would consider the negatives to be "the original" over the first photo that was printed using them.

I agree. The negatives are the developed film. They were physically present at the scene and were physically altered by the conditions at the scene. Digital photography has nothing quite like it.

Are the raw photos manipulated or are they just the original 1s and 0s unedited?

Not sure if there's any preprocessing before the processing.

Edit: I'm imagining a digital camera that cryptographicly signs each raw frame before any processing with a timestamp and GPS location. Would be the best you could probably do. Could upload it's hash to a block chain for proof of existence as well.

Edit: I guess the GPS system would need some sort of ceyptographic handshake with the camera to prove the location was legitimately provided by the satellite as well.

the original 1s and 0s

I think your issue starts there, you already have to decide how to build your sensor:

If it's a CMOS sensor how strong do the MOSFETs amplify? That should affect brightness and probably noise.
How quickly do you vertically shift the data rows? The slower the stronger the rolling shutter effect will be.
What are the thresholds in your ADC? Affects the brightness curve.
How do you layout the color filter grid? Will you put in twice as many green sensors compared to blue or red as usual? This should affect the color balance.
How many pixels will you use in the first place? If there is many each will be more noisy, but spacial resolution should be better.

All of these choices will lead to different original 1s and 0s, even before any post-processing.
