↳ In-reply-to » is the first url metadata field unequivocally treated as the canon feed url when calculating hashes, or are they ignored if they're not at least proper urls? do you just tolerate it if they're impersonating someone else's feed, or pointing to something that isn't even a feed at all?

(#abcdefghijkl https://example.com/tw.txt#:~:text=2025-10-01T10:28:00Z), because it can be simply hacked in to clients currently on hashv1 and provides an off-ramp to location-based addressing

I like that property (an off-ramp to location-based addressing), so I think I could live with that approach. ✅

(I’m not sure why we’re using text fragments, though. Wouldn’t that link to the first occurence of 2025-10-01T10:28:00Z? That’s not necessarily correct. And, to be proper URLs that Firefox and Chromium understand, it would also need to be written as 2025%2D10%2D01T10:28:00Z. The dash carries meaning, sadly. I think all this just creates needless complication. How about we just go with https://example.com/tw.txt#2025-10-01T10:28:00Z?)
