I’m saying this isn’t a debate. Adywan does what he wants. The fact that in the canon you quote actually has the Death Star finished at Scarif is the point. Why would the Empire move it from Geonosis to Scarif, then move it to Ganleigh for two days when the only difference between Scarif and Adywan’s planet is the shade of blue he already pointed out would have matched Scarif if people hadn’t convinced him to change it?
No, it is a discussion.
I did quote canon about Scarif? Other than talking about A New Hope, and merely mentioned the battle of Scarif, as a starting point, I don’t think I did.
I don’t seem to remember that in Rogue One the Death Star was finished at Scarif. In fact what I remember, that in the movie there was no planet visible when they installed the laser dish. I must be in some Disney book, but not in Catalyst for sure. Not that it really matters. I thought it was built at Geonosis, went to destroy Jedda, than moved to Scarif against the Rebels.
Anyway, if so, it makes no sense to build the Death Star in secrecy at one of the Main Data Storage Centers, which is a natural target for spies.
I don’t even know what Ganleigh is, that you mention.
