Compare folder ownership inheritance and POSIX mode boundaries

ScreenshotScreenshotScreenshot

Directory Ownership and Mode Matrix is a desktop filesystem ownership, POSIX permission
inheritance, and extended attribute boundary inspector for Linux. An independent Linux
utility inspired by AccessEnum, it walks directory trees, collapses subfolders and files
that cleanly inherit parent ownership and permission bits, and highlights only boundary
nodes where (UID, GID, mode) or extended attributes diverge from the parent directory.

Key Features:
- Ownership & Mode Inheritance Collapsing: Compares each directory and boundary file
against its parent folder's UID, GID, and octal permission mask, collapsing matching
descendants so administrators and developers can review permission transitions quickly.
- Read & Write Scope Matrix: Classifies effective read/traverse and write access scopes
(Owner Only, Owner + Group, World Readable, Group Writable, World Writable) alongside
SUID, SGID, and sticky mode bit indicators.
- POSIX Extended ACL & Xattr Decoder: Parses binary Linux system.posixaclaccess and
system.posixacldefault extended attributes directly from filesystem nodes into
human-readable user, group, mask, and other entries, resolving numeric UIDs and GIDs
against host passwd and group tables.
- Inheritance Analytics & Structured Export: Visualizes inheritance collapsing ratios
and mode profile distributions, and exports complete boundary matrices to CSV and JSON.
