   I have reached out to a couple different locations for help with 
BTRFS, and I have reached a dead end at my google-foo, and my 
distributions discussion boards.  If there is a better place to ask for 
help with respect to a hard file system crash, please let me know.
   I have a corrupted BTRFS file system, with a quick summary in bullet 
points:
-    single new NVME, 6 months old, 2Tb size, 1Tb used, 200Mb of really 
needed stuff
-    one backup exists, 6 months old, still need the new copies of above 
needed files
-    Fedora 39
-    chromium, high tab count, apparent culprit
-    hard system lock (no ssh response, no console switching)
-    repeated hard system restarts, last one crashed btrfs file system
-    btrfs hard failures:
-        parent transid;
-        checksum;
-        bytenr;
-        search for next directory;
-        can't read tree root;
-        bad tree block start;
-        212 found roots, none seem to have a "good match", as noted above

   I started looking into the kernel driver source code to help my 
understanding of the physical layout, and may build a more forensic 
method of retrieving the binary/text data that I need.  I hope there is 
something that is already included in the btrfs-progs packaging, 
available through the source code, or by the developer team itself.
