- Migration 027: agent_variants table with single-active enforcement, variant_id column on agent_performance_log - API: full CRUD, clone from agent/variant, activate/deactivate, per-variant performance metrics and history endpoints - Services: extractor, event classifier, thesis rewriter all wired to AgentConfigResolver with variant override support - Frontend: variant list, comparison view, create/edit/clone forms, activate/delete actions on Agents page - Tests: API tests + 5 property-based tests (single-active invariant, clone preservation, config resolution, slug determinism, update idempotence) - Spec files for agent-variants feature
