Release notes

Alexandria 0.5.0, build 7: discover your Towers from self-encrypted workspace records shared by compatible NStack apps, choose a Tower, then choose an accessible workspace. Fresh membership checks verify each connection. Newest saved records and deletion markers take precedence. Manual entry and retry remain available. Existing books, reading positions, notes and identity are preserved. Cross-app and multiple-Tower cases were tested with signed fixtures; physical Amber interaction remains unverified.
