# Blog App (Coop)

Content management, Ghost CMS sync, navigation, and the prose editor for the Rose Ash cooperative platform. Runs database migrations on startup and serves as the primary content hub.

## Structure

path_setup.py           # Adds project root + app dir to sys.path
entrypoint.sh           # Container entrypoint (migrations, Redis flush, start)
bp/
  blog/                 #   Post listing, Ghost CMS sync, webhooks

  fragments/            #   nav-tree fragment for cross-app navigation
models/                 # Re-export stubs pointing to shared/models/
services/               # register_domain_services() — wires blog + calendar + market + cart
templates/              # Blog-specific templates (override shared/)
```

## Cross-domain communication

All inter-app communication uses typed service contracts (no HTTP APIs):

- `services.calendar.*` — calendar/entry queries via CalendarService protocol
- `services.market.*` — marketplace queries via MarketService protocol
- `services.cart.*` — cart summary via CartService protocol
- `services.federation.*` — AP publishing via FederationService protocol

## Fragments served

- **nav-tree** — site navigation tree, fetched by all other apps

## Fragments consumed

- **cart-mini** (from cart) — cart icon + badge
- **auth-menu** (from account) — sign-in / user menu
- **container-nav** (from events, market) — sidebar widgets
- **container-cards** (from events) — event cards on listing pages
