September 21, 2026 · Web preview hardening

• Owned secret-buffer cleanup, immediate passphrase-form clearing and configurable idle locking.
• Complete KDBX terminal-block authentication and strict end-of-file checks, with KeePassXC round-trip and mutation regressions.
• Shared extension source now reviews exact origins and flags internationalized domains before filling.
• Local sample demo, a real product walkthrough, benchmark tool, security/disclosure guidance and public feature roadmap.

These web/source changes do not retroactively update native installers or developer extension archives. Listed native 0.3.3 builds predate this hardening; rebuilt, platform-tested releases are still required. iOS recording-cover source compiled for the simulator, not a signed phone distribution.

Earlier preview

Vault 0.3 added encrypted workspace pages, checklists and project boards alongside passwords/cards, with native Wi-Fi pairing and complete-copy review. Read the platform release boundaries.

No independent audit, paid cloud service, App Store approval or signed desktop publisher release is implied by this changelog.
