From bd5690e76c31d6655e59965b24492aa371e19c55 Mon Sep 17 00:00:00 2001 From: AkhileshNegi Date: Mon, 26 Oct 2026 12:58:53 +0530 Subject: [PATCH 1/4] fix(topic_relevance_llm): label the topic configuration in the prompt The v1/v2/v3 templates were appended to the raw `configuration` text with no header, so the model received a bare list (e.g. "cricket\nglific") followed by rules about "forbidden topic DESCRIPTIONS" and had to guess that the list was the forbidden set. Keyword-style configs typically scored 2 (ambiguous) and passed the default threshold. Each template now carries a `{{TOPIC_CONFIGURATION}}` placeholder inside a labelled block (allowed / forbidden / both), matching the convention the older `topic_relevance` validator already uses. The validator substitutes the config into the template instead of concatenating, and a template without the placeholder is rejected at load time.
