Replace every direct cross-app services.* call with HTTP-based communication: call_action() for writes, fetch_data() for reads. Each app now registers only its own domain service. Infrastructure: - shared/infrastructure/actions.py — POST client for /internal/actions/ - shared/infrastructure/data_client.py — GET client for /internal/data/ - shared/contracts/dtos.py — dto_to_dict/dto_from_dict serialization Action endpoints (writes): - events: 8 handlers (ticket adjust, claim/confirm, toggle, adopt) - market: 2 handlers (create/soft-delete marketplace) - cart: 1 handler (adopt cart for user) Data endpoints (reads): - blog: 4 (post-by-slug/id, posts-by-ids, search-posts) - events: 10 (pending entries/tickets, entries/tickets for page/order, entry-ids, associated-entries, calendars, visible-entries-for-period) - market: 1 (marketplaces-for-container) - cart: 1 (cart-summary) Service registration cleanup: - blog→blog+federation, events→calendar+federation, market→market+federation, cart→cart only, federation→federation only, account→nothing - Stubs reduced to minimal StubFederationService Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

"""Typed singleton registry for domain services.
|
|
|
|
Each app registers ONLY its own domain service. Cross-app calls go
|
|
over HTTP via ``call_action()`` (writes) and ``fetch_data()`` (reads).
|
|
|
|
Usage::
|
|
|
|
from shared.services.registry import services
|
|
|
|
# Register at app startup (own domain only)
|
|
services.blog = SqlBlogService()
|
|
|
|
# Use locally within the owning app
|
|
post = await services.blog.get_post_by_slug(session, slug)
