The v1 build of dead.air has a few geometry holes, presumably from node shenanigans. The map is UDMF and a large portion of the map's vertices are off-grid, which is likely what's throwing ZDBSP off.
Some gzdoom screenshots (clickable thumbnails) w/coordinates of the 4 reported trouble-spots:
The first 3 only manifest in GZDoom but #4 results in an ugly HOM in ZDoom as well, for those hunting for the issue.
This may be a "can't do much because floating point precision/rounding/whatnot" thing, but it's worth a report. I'll see if I can spot-fix these map-side in the meantime, but #4 in particular has resisted attempts to oust it so far.
[EDIT] Added a direct link to the old v1 build of the wad, since the v2 release patches up the symptoms mod-side.

Indeed missing geometry is caused by fractional part of vertex coordinates. Running ZDBSP from command line with -w options will output all of problems encountered:
Segs 35638* and 35643 have duplicate end vertex 14699 (-1275, 661)
Segs 43237* and 3313 have duplicate start vertex 1945 (3659, 133)
Segs 43237* and 3313 have duplicate end vertex 16645 (3659, 133)
Segs 55531* and 55528 have duplicate start vertex 19699 (-233, 14958)
Segs 60256* and 60258 have duplicate start vertex 20858 (833, 12984)
Segs 60256* and 60258 have duplicate end vertex 8944 (832, 12984)
Segs 61571* and 61564 have duplicate start vertex 21185 (232, 11665)
Segs 63660* and 63661 have duplicate start vertex 21707 (-1386, 13494)
Segs 63660* and 63661 have duplicate end vertex 8015 (-1380, 13493)

Some time ago I made a fairly simple hack for ZDBSP: I added a tolerance (or rather coordinate rounding) for vertices in UDMF which in theory should "solve" such issues automatically.
It worked more or less OK but I never tested it extensively.
Grid size 1 is too coarse to do the entire map, but probably the trouble spots can be snapped to 1 without causing any jaggies. I'd love to snap everything to, say, 0.25, but GZDB doesn't do fractional grid sizes and SLADE doesn't have a "snap vertices to grid" feature... though maybe I ought to feature suggest that already.
I'm curious to know if your hacked ZDBSP will fix the issues. It's a real-world test case at least.
So it is indeed the selection algorithm screwing up on too short lines. Just like I expected. I just posted in another thread a few days ago that Randi outright refused to address the bug where it could have been fixed for (in my opinion laughable) performance considerations (yeah, broken nodes are definitely better than a 5% speed loss...)
For what it's worth, I made a sweep for short linedefs and deleted quite a few (seems the last time I did this for the map was prior to adding the end arena; welp). This fixed the holes in screenshots #2 and #4, but #1 and #3 still persist, so there's still some voodoo at play.

I uploaded my ZDBSP build here. Compiled from the latest sources with my rough rounding hack.
Removed 13 lines with 0 length.
Removed 26 unused sidedefs.

Honestly I have no idea what problems my hack can introduce. You can give it a try if you want but use it on your own risk.
Super-thanks! That seems incredibly useful for evading this sort of thing in the future. If it fixes all the visible issues, then hurrah!
I'll bet those missing lines are legit mapping errors. There were several vestigial short linedefs I removed in my working copy; between that and some vertex jiggling I was able to oust the issues for the next release, but I'll probably use this ZDBSP build going forward to avoid having to do the vertex snap. Also because it may solve issues with another (secret, unreleased) map -- that's a side-note, but worth mentioning for funsies.
