spec/vm.sx — bytecode VM written in SX (the spec):
- Stack-based interpreter for bytecode from compiler.sx
- 24 opcodes: constants, variables (local/upvalue/global), control flow,
function calls (with TCO), closures with upvalue capture, collections,
string concat, define
- Upvalue cells for shared mutable closure variables
- Call dispatch: vm-closure (fast path), native-fn, CEK fallback
- Platform interface: 7 primitives (vm-stack-*, call-primitive, cek-call,
get-primitive, env-parent)
spec/tests/test-vm.sx — 72 tests exercising compile→bytecode→VM pipeline:
constants, arithmetic, comparison, control flow (if/when/cond/case/and/or),
let bindings, lambda, closures, upvalue mutation, TCO (10K iterations),
collections, strings, define, letrec, quasiquote, threading, integration
(fibonacci, recursive map/filter/reduce, compose)
spec/compiler.sx — fix :else keyword detection in case/cond compilation
(was comparing Keyword object to evaluated string, now checks type)
Platform primitives added (JS + OCaml):
make-vm-stack, vm-stack-get, vm-stack-set!, vm-stack-length, vm-stack-copy!,
primitive?, get-primitive, call-primitive, set-nth! (JS)
Test runners updated to load bytecode.sx + compiler.sx + vm.sx for --full.

Shared
Shared infrastructure, models, contracts, services, and templates used by all five Rose Ash microservices (blog, market, cart, events, federation). Included as a git submodule in each app.

Key Patterns
- App factory: All apps call
create_base_app()which sets up DB sessions, CSRF, error handling, event processing, logging, widget registration, and domain service wiring. - Service contracts: Cross-domain communication via typed Protocols + frozen DTO dataclasses. Apps call
services.calendar.method(), never import models from other domains. - Service registry: Typed singleton (
services.blog,.calendar,.market,.cart,.federation). Apps wire their own domain + stubs for others viaregister_domain_services(). - Activity bus:
emit_activity()writes toap_activitiestable in the caller's transaction.EventProcessorpolls pending activities and dispatches to registered handlers. Internal events usevisibility="internal"; federation activities usevisibility="public"and are delivered to follower inboxes by the wildcard delivery handler. - Widget registry: Domain services register widgets (nav, card, account); templates consume via
widgets.container_nav,widgets.container_cards. - Cart identity:
current_cart_identity()returns{"user_id": int|None, "session_id": str|None}from the request session.
Alembic Migrations
All apps share one PostgreSQL database. Migrations are managed here and run from the blog app's entrypoint (other apps skip migrations on startup).
