PR	What	Date	LEX	Impact
#1	Monorepo migration — frontend config for monorepo infra	Mar 29	—	Foundation: unified build system
#2	Storage controller/service with presigned URLs	Mar 30	LEX-201	Enabled file uploads for MM Docs
#3	User schema + auth service for new auth data	Apr 2	—	Auth foundation
#5	Shared contracts — Zod schemas + types	Apr 3	LEX-198	Key convergence: typed brain↔backend boundary
#6	Fix doclist script names to prevent `pnpm dev` errors	Apr 4	—	DX fix
#8	Auth refactor	Apr 6	—	Clean auth layer
#9	Auth infrastructure for email/sms/oauth (OPEN)	Apr 7	—	Multi-method registration

Патерн: foundational-first — монорепо → storage → auth → shared контракти. Найвищий PR volume (7 з 10). Єгор будує infrastructure layer на який потім накладаються Brain і Frontend.

#4	System prompt editor redesign	Apr 2	UX: custom system prompts per project
