1. I had no issues with it. In terms of 'that's not how things are done', I find people are v non-specific when it comes to how the Foundation operates. Each article should be able to stand alone, and all that.
Although if by provisional document you just mean, more information will be added as it becomes available, I'd always assume that was the case with any document. I assume that the articles as they are posted onto the site are snapshots from the Foundation database.
On balance I'd keep it as it is though. It's different, and gets you interested.
2. As long as its story keeps people interested, it should be alright.
3. Have Jones and Allard been put onto the International Space Station? I'm not sure I understand why the Foundation would do that. It seems a little expensive, and there's no actual evidence that this (humanhunting angler fish thing??) wouldn't be able to get them from space.
Hmm what does the whole earth rippling suggest.. Is it that the scip will be able to travel everywhere freely? Or is it a more immediate 'the world's about to end' type scenario. If it's the second one, then the first Coda is probably needed, just so we know how the world didn't end and the document was able to be uploaded.
The second Coda isn't worthless, but it seems like a bizarre place to end the story, so I'd probably end it on the first one.
4. A few nitpicks- it's a bit weird for the corporal to say 'this isn't a tea party' and then a bit later, referring to the glowsticks 'let's make this a party'. Overall that character might be going a little too far into the stereotypical 'gruff sergeant' for some people, but personally I didn't think she was too unrealistic.
Through the window the disc of the Earth can be seen. Its surface is boiling like a carp pond at feeding time
Also, whilst 'boiling like a carp pond at feeding time' is evocative, I'm not sure it fits the tone very well. You could probably find a way to insert that line into the dialogue if you wanted to.
Overall this is very good stuff- I'd definitely upvote this. Obviously you should show it to more people first- take it to the chat if you haven't already. My biggest concern is the space station stuff. It's certainly dramatic, but I don't really buy that they'd put AS and IJ up there. Why not just have different character(s) up there observing the Earth ripples?
