After a bit of reading forums and testing, I've found some things that can be edited in the game.
Saved game files (*.se1) are zip files with password GarfieldJonesCat containing temp.txt.
Extract to edit, and when you add it back to the save, you don't need to use the password.
This is not a plain text file, it's some sort of Binary Serialization format, but can be opened in a hex editor like FlexHEX.
Text strings and numbers are plain ANSI text, with a preceding byte determining the length. To change a number to have more digits, you need to modify that byte and insert or delete bytes, changing the length of the file.
Note: Using CoSMOS some details can be manipulated while the game is running but the text is then UTF-16, and you can't adjust the length of numbers.
Each number/string in the stats part of the file seem to be separated by 5 additional bytes, probably a signifier, be careful not to change them.
First, some simple finds. Search for the keywords as ANSI Text, and use Find All for easier navigation:
Fate Points = fatecardpoints
Look for the one with a bunch of number groups preceding it, the correct one will have a string fp and two groups of numbers before the keyword.
The first of the two is the number of fate points
e.g.
009FB8A0 | 02 66 70 06 76 32 02 00 01 33 06 77 32 | .fp.v2...3.w2
009FB8B0 | 02 00 01 34 06 78 32 02 00 0E 66 61 74 65 63 61 | ...4.x2...fateca
009FB8C0 | 72 64 70 6F 69 6E 74 73 | rdpoints
To change the 3 fate points, you need to change the string length from 01 to 03 and insert the extra 2 bytes.
009FB8A0 | 02 66 70 06 76 32 02 00 03 39 39 39 06 | .fp.v2...999.
009FB8B0 | 77 32 02 00 01 34 06 78 32 02 00 0E 66 61 74 65 | w2...4.x2...fate
009FB8C0 | 63 61 72 64 70 6F 69 6E 74 73 | cardpoints
Bureaucracy Points (BP) = orgCount
The correct one is slightly before the fate points indicator, with a bunch of numbers before and after.
The BP number is the 4th one before the keyword, setting it to 99,999 is massive overkill, and any higher will take the time between turns a lot longer.
This is used up each round to do all the council tasks, such as research, discovery and creating strategy cards.
Credits = orgCount
As BP, but 16 before; or 3 after militiaLeader in the same grouping.
Card Scrap Points = scrapPoints
Directly after keyword.
Card Craft Cost = scrapPointCost
Directly after keyword.
