You are still missing the point.
The codex entry PROVES that the Alliance knows that Cerberus is indeed building up. You keep insisting to no avail that is a throwaway but it is not.
The codex is actually part of the narrative, not just an explanation of the narrative in the series. It is told from an Alliance point of view (which can be odd for ME2).
The evidence says that yes, Bioware indeed did account and foreshadow a Cerberus fleet in Mass Effect 3 before Mass Effect 3. Its clear as day. To say otherwise is dishonesty.
And even speculation and hypothesis from characters and sources can be foreshadowing (not this case, but do read the Keeper codex in ME1).
I'm missing no point:
My point is that the Codex entry proves NOTHING. It does not prove that the alliance knows that Cerberus is building up anything. Indeed, there is no evidence that Cerberus is building up anything at all. As of Mass Effect Retribution, Cerberus has been dealt a critical blow by the Turians.
This is later retconned, without any explanation from BW. I'm not a fan of unannounced, unwanted, and unjustified retcons. It lacks internal consistency. And it makes me question their writing practices and capability.
The evidence that you say proves BW knew what they were doing does not exist. You are the only person making this claim. And in light of evidence against said claim, it is for good reason.
It makes me claim not only BW's credibility, but your credibility. Not only your credibility, but your capability, and indeed, even your attachment to sanity. And you do this routinely enough that I am fairly certain that you very likely have some kind of condition, disorder, or disability.
Speculation can indeed be foreshadowing. But there was literally no other event prior to the sudden change in characterization (that I suspect came from the change in leadership and writing at BW) where this was built upon or backed up. Foreshadowing is meant to be a lot more direct and visible and discernible than one line of ambiguous text in a codex entry that has no support or reinforcement anywhere else in the media. Thus, I directly deny the statement's purpose as foreshadowing. I directly and completely deny your claim's veracity.
And if that makes me dishonest in your eyes, I'm prepared to live with that. I'm quite certain that in this case, nearly everyone else shares my perspective that this line of text is meaningless. And I think they're with me when I say that you're trying too hard.
A lot of madmen think they're genius and brilliant. You're no exception.
