From bce36c1b34b7e292f4632e8d6a22fd5850b2abd2 Mon Sep 17 00:00:00 2001 From: Pratyush Sharma <56130065+pratyush618@users.noreply.github.com> Date: Thu, 12 Mar 2026 20:25:40 +0530 Subject: [PATCH 1/8] Add virtual thread parallel evaluation and progress callbacks Adds bounded-concurrency parallel evaluation using virtual threads (Executors.newVirtualThreadPerTaskExecutor + Semaphore), progress callback interface with ETA estimation, and a console progress bar implementation.

LLM-judge StepLevelErrorLocalization pinpoints the first reasoning trace failure. TopicDriftDetection tracks conversation coherence via embedding similarity to the initial topic. ConversationResolution judges whether the conversation achieved its goal.
