I'm in the midst of sifting through as many texts as I can find which offer up versions of the pyramid texts in their forms, such as the Book of Gates, Caverns, Journey through the Amduat etc in order to define which 'spells' or stages of the journey are the ones which do convey what actually went on inside the pyramid that the Pharaoh did or experienced in his recreation of the Sun's 'resurrection'.
What this means is Pharaoh is mimicking the twelve hours associated with the midnight journey of the Sun as it passes through the winter solstice. OMR has this image to show the locations of the Sun but it is not the night journey being undertaken as portrayed in the Sun being below the horizon and going through a different sky...it is what the image shows but you have to incorporate the Sun's locations against the static image above (Sorry, I misplaced that image at the moment but it isn't too hard to go between both images and imagine the Sun going through the above image)
The first location of the Sun is exactly one hour before dawn, in the intersection of the entrance and ascending passages, and as it makes its way 'through the pyramid' it arrives at certain locations according to the cosmos. The fun part is what happens at each hour according to the texts and how they correlate to what Pharaoh is doing at each hour, up until the fifth hour where it and a few more hours are wholly occurring within the middle chamber. For the Sun, hours five to six are where the Stars of Water reside...hour seven is on the southern meridian. While the Sun continues its journey 'through the pyramid', Pharaoh continues his journey up into the upper chamber where all things are resolved with the Sun being resurrected, Pharaoh being resurrected, and teh pyramid having been the stage within which the two have become one.
Ah, but there does seem to be a whole third layer of meaning to all this because Re and Osiris are included in the texts/tales/myths because they are involved also...especially as portrayals of the Sun on one hand, and as Lord of the Underworld on the other hand. And there is Pharaoh representing both as well as himself, as not just a King and worthy of being the figurehead for not only his people but also the land, but also extending himself as being the Earthly medium connecting 'As above, so below'...being a conduit for what celestial powers/other worldly powers can offer.
Okay...I say all this because, besides my analysis and overlays which folk have trouble with, the pyramid texts do offer what it is the pyramid is for and how it works. Folk like to think of the pyramid as being a repository for a dead man while in fact it was a device to enable observations of celestial mechanics at work to be portrayed, and for a man to mimic those portrayals through recreation of certain scenes and events where he too was 'resurrected' via particular sciences understood at the time, and incorporated into the pyramid in real terms.
In all that you have tried to understand Sam, there are quite a few pyramid texts from different periods which offer up various versions of what was considered important to follow so the Pharaoh did what was required in mimicking other things. Some texts have more information and others have particular information which shows the celestial landscape and shows the winter solstice Sun, and they relate to what Pharaoh is doing and going through so that the pyramid is a 'correct' setting for the whole dramas being played out. On the one hand, the King is the pyramid, and on the other hand, the pyramid is the King. But the pyramid is also a representation of the cosmos, and also a representation of Earth, and these have to be scaled versions in order for the 'magic' of the entire drama to actually work.
When you think of specific scenes/hours/stages of the journeys being undertaken 'in the underworld' for the 'resurrection' of Sun/Pharaoh/Osiris, you can actually see - according to overlays and locations within the pyramid - the interaction between all involved.
If you can grasp what the pyramid texts offer, and incorporate OMR in its findings, you get a clearer picture of how to translate some of things you are trying to translate. I mentioned the red and blue lightning and the thunder-sounds - I still haven't found the link I read this in because my old laptop broke down and I lost all the info, but I'll find it again and link it - which relate to a part of what happened inside the middle chamber in the fifth or sixth hour. It further goes on to say that Isis/her representative goes in to 'do her thing' so resurrection does occur successfully...and she is just one attendant during the whole 'journey'.
As the entirety is to do with the 'resurrection of the Sun' which certainly indicates the winter solstice, we do need a celestial setting and the Sun's hourly locations on the solstice in order to identify what constellations are where, and where the Sun is according to them, and then the pyramid texts can be read properly...they do open up a whole layer of understanding that has been lost amid so many texts and translations and versions.
Certainly I have only read the various texts and take them as-is without inferring another meaning to a hieroglyphic translation for what I read, but I do read them for what they are in relating to the images I post and what the Pharaoh did in his own journey through the pyramid...and what the correlating scenes actually mean.
I hope this helps in you furthering your translations and what you are doing in portraying the King as Pyramid.
