Shrubbery: Application Development For Urbit
summary
Shrubbery claims a replacement application layer for Urbit that actually constrains the global namespace via hierarchical Shrubbery “shrubs” which are ACID, relocatable units; each shrub is message‑passing code with relocatable shrubs as primary keys, injected dependencies for wallets/inboxes, and structural polymorphism so multiple message versions coexist. The build system moves into user space enabling other languages, there’s a live demoed HTML UI and spreadsheet-like editor, and failure semantics give clear transactional boundaries while security is still unfinished.
