Full Vault Encryption & Aegis Partitions
Architectural boundaries that guarantee your private life stays private, even when autonomous AI agents collaborate in your workspace.
1-Click Total Vault Encryption
Want absolute peace of mind? Seal your entire vault with unbreakable, bank-grade encryption using a single master password. Only you hold the key. Even if your computer is physically stolen or your cloud backup drive is compromised, your notes remain 100% scrambled and unreadable to anyone else.
Every encrypted Sphene vault includes an independent recovery tool that unlocks your files using standard tools found on every Mac and Linux system. Even if Sphene ceases to exist, you can always recover your notes with a single command.
./decrypt_vault.sh --vault /path/to/vault.enc --out /path/to/notes
Hardware-Grade Vault Partitions
Unlike flat folder structures where AI agents have unrestricted access to all your notes, Sphene enforces kernel-level permission boundaries across 4 dedicated zones:
Workspace/
Your active thinking space. Read and write access for you; collaborative staged read/write access for autonomous AI agents.
Agent edits are staged as diffs for your explicit human review with 1-click accept or reject.
Reference/
Permanent ground truth: curated literature, books, papers, and verified facts. Full write access for humans.
AI agents have read-only access. Bots are mathematically barred from altering your source literature.
Private/
Personal reflections, journals, finances, and private research. Completely locked and encrypted on disk—strictly blocked from all AI access.
Zero agent access. The kernel returns 403 Forbidden to any AI query targeting this partition.
Drawing/
Dedicated visual workspace provided by Drawing Studio. Mind maps, flowcharts, architecture diagrams, and freehand sketches.
Visual shapes automatically serialize to standard Mermaid syntax and vector Markdown.
The Differential Timeline ("Human Veto")
Traditional AI assistants silently overwrite text or erase nuances. Sphene introduces Git-like block review for autonomous agents:
1. Block-Level Staging
When an autonomous agent proposes an edit via the REST API or MCP gateway, the kernel intercepts it and stores it in the Differential Timeline staging area.
2. Interactive Visual Diff
Open the note to see red/green side-by-side diff highlights. Inspect additions, deletions, and source reasoning without committing anything to disk.
3. 1-Click Accept or Rollback
Accept the change with a single click, or exercise your human veto to reject it instantly. Your personal knowledge vault never suffers AI degradation.
