# ext4 ## Identification `inode/directory` is a MIME type; [[ext4|ext3/ext4]], [[Filesystem in Userspace|FUSE]], [[MS-DOS FAT|MS-DOS/FAT]], and possibly [[NTFS|NTFS]] are filesystem or filesystem-interface labels. Google Actions Console and Firebase Console were developer control planes for assistant actions and app backends. ## Notebook evidence - [[Scanned_20260730-1719#PDF page 35 — Filesystem types and console projects|PDF page 35: Filesystem types and console projects]] — The author appears to be inventorying mounted storage volumes or project folders, then recording cloud consoles used to configure an application. This is another local/remote duality: filesystem state on the device versus hosted project state. ## Relationships and overlays The source places this note in a shared evidence cluster with [[Filesystem in Userspace|Filesystem in Userspace]] · [[MS-DOS FAT|MS-DOS FAT]] · [[NTFS|NTFS]] · [[Scanned_20260730-1706|Scanned_20260730-1706]]. Within the larger collection, this evidence extends [[Vendor-Agnostic Recovery|vendor-agnostic recovery]] and [[Continuity Architecture|continuity architecture]] by showing how software, hardware, identity, and pre-OS control depend on recoverable interfaces. ## Evidentiary status and open leads Record mount point, block device, UUID, filesystem, label, and source project together. The current page loses those mappings. ## Source - [[Scanned_20260730-1719|Scanned_20260730-1719]] ## Scanned_20260730-1314 overlay [[Scanned_20260730-1314#Scanned_20260730-1314.pdf — PDF page 28|Pages 28 and 39]]: ext4 appears in both Linux disk-layout work and Android custom-ROM storage policy. **Relationship overlay:** [[F2FS]] · [[GUID Partition Table]] · [[OmniROM]].
