+# Test Case: Extended Inode Size Above OFF_MAX
+
+**Test ID**: TC151-extended-inode-off-max
+
+## Objective
+
+Rerun rejection of an extended inode with bit 63 set in `i_size` on the current
+exact KLD, before open, read, mmap, or pager setup.
+
+## Fixture
+
+Use `images/extended-size-bit63.erofs`. Evidence asserts a 64-byte regular
+inode, exact NID/offset, `i_size=0x8000000000000000`, valid CRC, and image hash.
+Compile `read_probe` and `mmap_fault` natively in FreeBSD.
+
+## Procedure
+
+Mount the image, then run every acquisition twice:
+
+```sh
+./read_probe expect-error "$mnt/oversize.dat" 97
+./read_probe expect-error "$mnt/oversize.dat" 97
+set +e
+truss -o /tmp/tc151-stat.truss stat "$mnt/oversize.dat"; stat_rc=$?
+./mmap_fault "$mnt/oversize.dat" > /tmp/tc151-mmap1 2>&1; mmap1_rc=$?
+./mmap_fault "$mnt/oversize.dat" > /tmp/tc151-mmap2 2>&1; mmap2_rc=$?
+set -e
+printf 'stat_rc=%d mmap_rc=%d,%d\n' "$stat_rc" "$mmap1_rc" "$mmap2_rc"
+tail -20 /tmp/tc151-stat.truss
+cat /tmp/tc151-mmap1 /tmp/tc151-mmap2
+```
+
+Record dmesg delta, remove outputs, unmount, detach, and unload the exact KLD
+at the end of G1.
+
+## Expected Results
+
+- All direct opens and traced `stat` fail with errno 97 (`EINTEGRITY`).
+- Both mmap helpers exit 1 at `open` with the same error; no fd reaches mmap or
+  pager setup.
+- No negative pager size, trap, panic, stale vnode, or cleanup residue occurs.
+- Historical TC151 output cannot substitute for this current-KLD rerun.
