All checks were successful
Test Asgard Runner / test (push) Successful in 2s
Phase 4 Contributions (Agent Golf): - Module auto-installation service (module_installer.rs) - NATS subject pattern for module installation commands - Companion agent contract documentation - API endpoint: POST /api/modules/install Phase 5 XO Direct Touch: - Webstore subscription API (PayPal recurring billing) * POST /api/webstore/subscription/create * GET /api/webstore/subscription * POST /api/webstore/subscription/cancel * POST /api/webstore/subscription/webhook - Store configuration API (CRUD for store settings) * GET /api/webstore/config * PUT /api/webstore/config - Store category/item management APIs (multi-tenant CRUD) * GET/POST/PUT/DELETE /api/webstore/categories * GET/POST/PUT/DELETE /api/webstore/items - Public store API (customer-facing, subdomain-scoped) * GET /api/public-store/:subdomain * GET /api/public-store/:subdomain/items * POST /api/public-store/:subdomain/purchase * POST /api/public-store/:subdomain/webhook - Transaction history API * GET /api/webstore/transactions - Delivery system (NATS command execution on purchase) - Migrations: payment_orders, webstore_subscriptions, store_config, store_items, store_transactions Security: - JWT auth + license_id scoping on admin endpoints - Subdomain → license_id mapping on public endpoints - Purchase limit enforcement - Command injection prevention via placeholder replacement Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
