SxExpr is now a str subclass so it works everywhere a plain string does (join, isinstance, f-strings) while serialize() still emits it unquoted. sx_call() and all internal render functions (_render_to_sx, async_eval_to_sx, etc.) return SxExpr, eliminating the "forgot to wrap" bug class that caused the sx_content leak and list serialization bugs. - Phase 0: SxExpr(str) with .source property, __add__/__radd__ - Phase 1: sx_call returns SxExpr (drop-in, all 200+ sites unchanged) - Phase 2: async_eval_to_sx, async_eval_slot_to_sx, _render_to_sx, mobile_menu_sx return SxExpr; remove isinstance(str) workaround - Phase 3: Remove ~150 redundant SxExpr() wrappings across 45 files - Phase 4: serialize() docstring, handler return docs, ;; returns: sx Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

OAuth2 SSO
Federation is the authorization server for all Rose Ash apps:
/oauth/authorize— authorization endpoint (PKCE supported)- Magic link login (passwordless email)
- All client apps auto-get
/auth/login,/auth/callback,/auth/logoutviashared/infrastructure/oauth.py - Per-app first-party session cookies (Safari ITP compatible)
ActivityPub
- Per-app actors: each app has its own AP actor (virtual projection of the same keypair)
- Actor endpoints: webfinger, actor profile, inbox, outbox, followers
- Social features: timeline, compose, search, follow/unfollow, like/boost, notifications
- Activities emitted to
ap_activitiestable, processed byEventProcessor - HTTP signatures + IPFS content addressing
