+## [Unreleased]
+
+### Fixed
+- Count hard-link allocation once in a deterministic traversal order while
+  retaining apparent sizes per pathname. Filtered comparison has independent
+  allocation ownership, including when the first link is ignored.
+- Report filesystem errors and incomplete ancestor totals instead of silently
+  dropping errors or treating vanished entries as accessible empty directories.
+- Inherit ignore rules when scanning nested directories; accept dangling
+  symlinks as scan targets and distinguish special files from directories.
+
+### Added
+- A scanner module with structured reports, file identities, progress counters,
+  cooperative cancellation, and per-scan thread pools.
+- Optional `-x` / `--one-file-system` boundary handling. Partial CLI reports
+  return a nonzero exit status and include `complete` in JSON output.
