From ce7df91a4210e23e0028b061556ddee8268e9906 Mon Sep 17 00:00:00 2001 From: robbond Date: Thu, 8 Oct 2026 09:59:03 +0100 Subject: [PATCH] test(confidence-engine): enable live current understanding experiment execution Extend the CU synthesis experiment helper with a --live flag that uses the production provider (getProvider from lib/llm/provider.js) for live model invocation. Preserves deterministic mode unchanged. Adds 10 new deterministic tests verifying live-mode wiring via injected mock provider: fixture pass-through, single invocation, schema correctness, immutability, persistence safety, and regression of existing deterministic behaviour. Zero network calls in all tests.
