giles c0665ba58e Adopt Step 7 language features across SX codebase
112 conversions across 19 .sx files using match, let-match, and pipe operators:

match (17): type/value dispatch replacing cond/if chains
  - lib/vm.sx: HO form dispatch (for-each/map/filter/reduce/some/every?)
  - lib/tree-tools.sx: node-display, node-matches?, rename, count, replace, free-symbols
  - lib/types.sx: narrow-type, substitute-in-type, infer-type, resolve-type
  - web/engine.sx: default-trigger, resolve-target, classify-trigger
  - web/deps.sx: scan-refs-walk, scan-io-refs-walk

let-match (89): dict destructuring replacing (get d "key") patterns
  - shared/page-functions.sx (20), blog/admin.sx (17), pub-api.sx (13)
  - events/ layouts/page/tickets/entries/forms (27 total)
  - specs-explorer.sx (7), federation/social.sx (3), lib/ small files (3)

-> pipes (6): replacing triple-chained gets in lib/vm.sx
  - frame-closure → closure-code → code-bytecode chains

Also: lib/vm.sx accessor upgrades (get vm "sp" → vm-sp vm throughout)

2650/2650 tests pass, zero regressions.

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

app.py                  # Application factory (create_base_app + blueprints)
path_setup.py           # Adds project root + app dir to sys.path
entrypoint.sh           # Container entrypoint (migrations, Redis flush, start)

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
