 This design means most new SDR metadata types are handled automatically without code changes. Only types requiring specialized behavior need explicit overrides in `handlerMap`.
 
-`MetadataBoundaryResolver` creates a `MetadataElement` — a value object capturing the parsed identity of the diff line: base path, extension, parent folder, component name, and path segments after the type directory. It may scan the git tree to find the component root when the directory name isn't present in the path.
+`MetadataBoundaryResolver` creates a `MetadataElement` — a value object capturing the parsed identity of the diff line: base path, extension, parent folder, component name, and path segments after the type directory. Resolution follows a tiered strategy to minimize git I/O: (1) flat paths (single segment after the type directory) use `MetadataElement.fromPath()` directly; (2) types with no suffix (LWC, Aura) use `fromPath()` since the scan cannot identify them; (3) depth-2 paths where the file contains the metadata suffix extract the component name directly from the file name without git I/O; (4) deeper paths delegate to `scanAndCreateElement()` which calls `getFilesPath(typeDir)` — a single recursive `git ls-tree -r` per type directory, cached hierarchically — then builds a Set of component names from meta files and matches path segments inner-to-outer. This handles intermediate folders between the type directory and the component (e.g., `permissionsets/marketing/Admin/...` where `marketing` is an organizational folder, not the component). For paths where the type directory is not in the path, a fallback walk-up strategy lists directory siblings via `listDirAtRevision` and matches against known metadata suffixes, with results cached per revision via `dirCache`.

+Handles types that can exist in either monolithic format (single file) or decomposed format (folder with sub-files). Detects the format at construction time. Locates the PermissionSet directory using a fixed offset from the file path's end, supporting arbitrary nesting depth (e.g., `permissionsets/marketing/Admin/fieldPermissions/...`).
