Vault Format

A vault is organized around encrypted metadata, encrypted content, and an encrypted tree index.

Components

• vault.config — encrypted metadata including salt, KDF parameters, and versioning
• d/ — encrypted file content
• m/tree.json — encrypted directory tree index

Operational notes

• File content is encrypted in chunks
• Directory and filename information is protected
• Integrity checks are part of the design, not a separate afterthought
• Layout details may evolve before the format is declared stable
