The first cross-domain federated workflow — behaviors defined by TYPES, across domains.
- events.rose-ash.com is now a fed-sx PEER: a lib/host instance with SX_DOMAIN=events whose 'calendar'
TYPE declares an on-allocate behavior. Replaces the Python events service (no strangler). serve.sh
gates domain types/behaviors on SX_DOMAIN (blog=article publish/digest; events=calendar+allocate).
- DIRECTED cross-domain delivery: an activity with :to <peer-base> is delivered to that peer's inbox
(∪ followers). The wire gains 'to'. So 'allocate' targets the events peer specifically.
- host/blog--allocate-activity/allocate! + POST /:slug/allocate?calendar=<id>; the events calendar
type's allocate-link DAG (an execute-fold effect) fires on receipt.
- docker-compose: the sx_events service (own store, shared SX_FED_SECRET, externalnet for a future
events.rose-ash.com Caddy route).
LIVE PROOF: publish 'Gig Night' on blog.rose-ash.com → POST /gig-night/allocate?calendar=main → the
events peer RECEIVES the directed, signed activity (/activities: 'allocate article gig-night') and
its calendar type's on-allocate behavior FIRES (/flows: 'linked gig-night'). blog 218/218, full
conformance green.
NEXT: events runs lib/events (real calendars/recurrence/ticketing); link event→post; shop
(lib/commerce) sells tickets — same federated, type-declared shape.
