In my opinion, that technote is a bit unclear on how this should work.

There are 3 different file "entries" that matter: volume header (first entry
on block $0002), subdirectory header (first entry of the first block of
a subdirectory), and all other file entries.

This email will use nomenclature that does not match the documentation: ignore
the first 4 bytes of any directory block, and consider each entry to be $27
bytes, this includes volume header and subdirectory headers.

Pre GS/OS 5: in all entries (volume header, subdir header, any other file
entry), offsets $1c and $1d are VERSION and MIN_VERSION. (The official
documentation considers the volume header and subdir header to start at
byte $000 and so VERSION and MIN_VERSION are at absolute offsets $20 and
$21).

Post GS/OS 5 (add lowercase flags):
For volume header, $16,$17 are the lower_case flags, and $1c
and $1d remain VERSION and MIN_VERSION
For normal file entries: $1c,$1d are the lower_case flags.
For subdirectory headers: It's not defined what to do.

I guess you've looked at GS/OS images, and subdirectory headers should not
change: $1c,$1d should be VERSION and MIN_VERSION, and there are no
lower_case flags, right (they DO NOT move to $16,$17 like the volume header)?

On Friday 24 June 2022 visited Magus Books and bought out all eighty of their most excellent "Magus Books" postcards.

On Saturday 25 June 2022 swam in Green Lake for the first time in 2022. Water very cold. Found a child's bracelet on bottom of lake. En route back from lake met Japanese "computer science" student, took her out on coffee date to discuss "jinko zuno" -- Japanese ("artificial brain") term for AI. .Could be a field agent working for Japanese Ministry of Stolen Technology, but how were they able to position agent in place so well? Ah, well.
