contents:
  /small.txt — "control\n" (8 bytes)
  /huge/     — 70000 zero-length files (file_00001.txt .. file_70000.txt)
               forces htree past its legacy 2-level cap (LARGEDIR ro_compat).
test_targets:
  - htree::lookup_leaf descends > 1 internal level to resolve /huge/file_NNNNN
  - readdir of /huge returns 70002 entries (70000 + . + ..)
  - random-sample stat on file_00001 / file_35000 / file_70000 all succeed
