Roadmap
Current prototype scope and planned development for HeartSuite Joint File System.
Prototype: HJFS is under active development.
Current capabilities
HJFS currently includes the following capabilities:
| Capability | Notes |
|---|---|
| Per-program file isolation | open() interception — programs are confined to their own storage area |
| Per-version storage | Each installed program version receives its own isolated storage area |
| Version rollback | Non-destructive — prior versions and their data remain intact |
| Secure file transfer | Copy utility and transfer area for explicit cross-program data movement |
| Trash-only deletion | Programs cannot permanently delete files. Permanent deletion requires explicit user action through a separate utility |
| Automatic data file backup | Every data file version is backed up to a protected area inaccessible to ordinary programs |
| Version management utilities | HJFS_update_program and HJFS_version_manager |
HJFS implements core file organization with the host file system code left unchanged — enabling deployment on standard, unmodified kernels. See Architecture and compatibility for details.
Planned
Next release
| Item | Notes |
|---|---|
| FS source code integration | Integrates minimal HJFS source code into the host file system’s open() call. Required for production deployment |
| Kernel registration | Registers the HJFS-modified file system with the kernel. Requires FS vendor cooperation on non-Linux platforms |
Subsequent releases
| Item | Notes |
|---|---|
| Network access control | New outbound connections are mediated by the OS. Desktop deployments prompt the user for confirmation; server deployments apply policy rules |
| Python script compartmentalization | Confines individual Python scripts to separate file spaces. Scripts no longer share the interpreter’s storage area. Requires a small amount of kernel cooperation |
| Advanced protection | Separates internal and user files and introduces OS-mediated file dialogs. Requires application updates. See Advanced Protection for design details |
