Actually I'm going to toss out some ideas here and brace myself...
1) Considering the fragments we do possess I hypothesize the Egyptians kept records of almost everything discussed in the court of Pharaoh. We have found some fragments recording such diverse subjects as food consumed by workforce, tributes tendered, names of key workers, some trial charges and sentences, land grants, etc.
2) I believe the statement "Thus let it be written, thus let it be done" survives in multiple evidence of court records... (please note the written part).
3) I therefore hypothesize the amount of surviving text, particularly papyrus scrolls, is our limiter, not what they didn't write.
4) I'm sure the first builders that wanted to take tombs from mastabas to pyramids had to justify it to the court, possibly including physical as well as metaphysical reasons for the change. The fact that we weren't lucky enough to recover those arguments is, imho, due to the lack of survival of the records, not the lack of original records in the first place.
5) The bent pyramid is a good example of a new idea that didn't work out right the first time round. I would guess the reasons for and against, judgment of who was at fault, even perhaps penalties for the same persons, would have all been overseen by Pharaoh and recorded. Again, tis a shame they didn't make the survived list.
6) Most scrolls we do have were entombed with the owners.
Unfortunately the scrolls that would help us the most are the least likely to be preserved that way.
I welcome any and all discussion on the above please.
