+# Test Case: Many Small Files
+
+**Test ID**: TC124-many-small-files  
+**Category**: Boundary & Stress  
+**Priority**: High  
+**Regression**: None
+
+## Objective
+
+Verify exact names, count, sizes, and hashes for 12,000 one-KiB files spread
+over 12 directories.
+
+## Preconditions
+
+- Complete `G7-MANUAL-SETUP.md` and verify the source inventory.
+
+## Manual Steps
+
+```sh
+G7=/root/repo22-g7
+FIX=$G7/fixtures
+SRCROOT=$FIX/sources/boundaries
+IMAGE=$FIX/images/boundaries.erofs
+MNT=/mnt/repo22-g7-tc124
+E=$G7/evidence/TC124
+mkdir -p "$MNT" "$E"
+unit=$(mdconfig -a -t vnode -f "$IMAGE")
+mount -t erofs -o ro "/dev/$unit" "$MNT"
+(cd "$SRCROOT" && find many-small -type f -print | sort) > "$E/source.names"
+(cd "$MNT" && find many-small -type f -print | sort) > "$E/target.names"
+source_count=$(wc -l < "$E/source.names" | tr -d ' ')
+target_count=$(wc -l < "$E/target.names" | tr -d ' ')
+printf 'source_count=%s\ntarget_count=%s\n' "$source_count" "$target_count" \
+  | tee "$E/counts.txt"
+test "$source_count" -eq 12000
+test "$target_count" -eq 12000
+cmp "$E/source.names" "$E/target.names"
+(cd "$SRCROOT" && find many-small -type f -exec sha256sum {} + | sort) \
+  > "$E/source.hashes"
+(cd "$MNT" && find many-small -type f -exec sha256sum {} + | sort) \
+  > "$E/target.hashes"
+cmp "$E/source.hashes" "$E/target.hashes"
+test "$(awk '$3 ~ /^sources\/boundaries\/many-small\// && $2 != 1024 \
+  { bad++ } END { print bad + 0 }' \
+  "$FIX/SOURCE-INVENTORY.tsv")" -eq 0 || \
+  awk '$3 ~ /^sources\/boundaries\/many-small\// && $2 != 1024' \
+    "$FIX/SOURCE-INVENTORY.tsv"
+umount "$MNT"
+mdconfig -d -u "${unit#md}"
+test -z "$(mount -p | awk -v m="$MNT" '$2 == m { print }')"
+test -z "$(mdconfig -l | tr ' ' '\n' | grep -x "$unit")"
+```
+
+## PASS Gate
+
+- Source and mounted name lists are identical and contain exactly 12,000
+  files.
+- Every mounted SHA256 row equals the corresponding source row.
+- Every many-small source file is exactly 1024 bytes.
+- No missing inode, panic, hang, or cleanup leak occurs.
