Compare folder ownership inheritance and POSIX mode boundaries
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.posix_acl_access and system.posix_acl_default 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.
