KeyPlus architecture and security documentation
The former combined architecture page described the legacy KeyPlus 0.2 design. KeyPlus 0.3 now separates these subjects:
- Security design documents Argon2id, AES-GCM, secret handling, file permissions, clipboard behaviour, and security boundaries.
- Technical overview documents application layers, the shared service, sessions, persistence, migration, and the internal vault envelope.
This compatibility page preserves the previous URL without repeating details that could drift or implying that KeyPlus exposes a supported public API.
