Thank you for the thorough answer. That is all quite methodical and impressive, bringing together good ideas from disparate projects into a single solution with new benefits. For people like me who have battled this demon before, it would help to explicitly say that you support any gzip file by way of this special magic. At least on my cursory reading of your page I did not understand this. And I never heard of gzrecover, so thanks for that too. I like how the pugz paper starts with "Decompressing a file made by the gzip program at an arbitrary location is in principle impossible." Until today I believed the same!
