Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 46s
Every .sxbc shipped with `:bytecode (nil nil ...)` and `:arity nil`, so the WASM
kernel's vm.sx hit "VM: unknown opcode 0" on every module and fell back to .sx
source (slower, noisy console). Root cause: `raw_serialize` in the `compile-blob`
command (sx_server.ml) handles `Number` but not `Integer`, and bytecode opcodes +
arity/upvalue-count are `Integer`s — so they fell through to the `_ -> "nil"`
catch-all and serialized as nil. Same class of bug as the value_to_js Integer gap
(689dae7d). It went unnoticed because source-fallback masks it. Add the Integer
case and regenerate: the web stack now loads entirely from bytecode (0 unknown-
opcode warnings, 0 source fallbacks), boost + SPA unchanged. compiler.sx in the
bundle was also stale — re-synced to the canonical lib/compiler.sx.
Verified: native host conformance 271/271; chromium boots with 0 unknown-opcode
warnings + 0 source-fallback loads; spa-check still passes (boost 6/6, fragment
swap). Prereq for content-addressing the assets (caching real bytecode, not nil).
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).
