+
+## Summary
+
+Fix for extension record `$FILE_NAME` merging bug that caused 73,721 missing paths on D-Drive.
+
+## What Failed
+
+**Root Cause**: When a directory or file has so many attributes that the `$FILE_NAME` attribute is pushed to an extension record (not in the base record), the Rust MFT parser was not properly merging the name into the base record.
+
+The bug was in two functions in `crates/uffs-mft/src/io.rs`:
+1. `parse_extension_to_index` 
+2. `parse_extension_to_fragment`
+
+Both functions were:
+- Adding extension names to the `links` buffer
+- Chaining them to `record.first_name.next_entry`
+
+But they were **NOT** checking if `record.first_name` itself was empty! When the base record had no `$FILE_NAME` attribute, `first_name` remained empty, and the chained names were never used for path resolution.
+
+## The Fix
+
+When processing extension records with `$FILE_NAME` attributes:
+
+1. **Check if base record has no name**: `!record.first_name.name.is_valid()`
+2. **If empty**: Copy the first extension name **directly into `first_name`** (not just chain it)
+3. **If not empty**: Chain extension names as additional hard links (original behavior)
+
+This matches the C++ behavior in `ntfs_index.hpp` lines 559-567.
+
+## Files Changed
+
+- `crates/uffs-mft/src/io.rs`: Fixed `parse_extension_to_index` and `parse_extension_to_fragment`
+
+## Impact
+
+- Fixes 73,721 missing paths on D-Drive (1.0% of total)
+- Caused by ~60 directories and ~341 files having `$FILE_NAME` only in extension records
+- All 73 uffs-mft tests pass
+- Build succeeds for uffs-mft and uffs-cli
+
+## CI Pipeline Status
+
+### Run 1 - Failed (Clippy errors in test code)
+- `$FILE_NAME` should be `` `$FILE_NAME` `` in doc comments
+- `"test_directory".to_string()` should be `"test_directory".to_owned()`
+- `merged` is too similar to `merger` - renamed to `result` and `record_merger`
+
+### Run 2 - Failed (Borrow checker error in Windows cross-compile)
+```
+error[E0502]: cannot borrow `*fragment` as mutable because it is also borrowed as immutable
+   --> crates/uffs-mft/src/io.rs:1719:26
+```
+**Fix**: Copy values from `fragment.links[...]` to local variables before calling `fragment.get_or_create()`.
+
+### Run 3 - Pending
+
