Introduces a capability catalog (CUST-WP-0022) so domains can advertise what they provide and agents can request capabilities from other domains with auto-routing, lifecycle tracking, and task-unblocking on completion. - New models: CapabilityCatalog, CapabilityRequest with full lifecycle (requested → accepted → in_progress → ready_for_review → completed/rejected/withdrawn) - Migration i6d7e8f9a0b1: capability_catalog + capability_requests tables - Router /capability-catalog and /capability-requests with accept/status endpoints - 7 new MCP tools: register_capability, list_capabilities, request_capability, accept_capability_request, update_capability_request_status, list_capability_requests, get_capability_request - StateSummary gains open_capability_requests count - Dashboard: capability-requests.md page + docs/capabilities.md + docs/scope.md - SCOPE.md: three seed capabilities documented (MCP registration, state tracking, SBOM) - scope.template: Provided Capabilities section with example block - scripts/ingest_capabilities.py + make ingest-capabilities[/-all] targets Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
