From 0174e37e1188eb6db7716fa9780e1a2fc501ec37 Mon Sep 17 00:00:00 2001 From: Deep Kumar Singh Kushwah Date: Wed, 10 Jun 2026 02:16:08 +0530 Subject: [PATCH] fix(gateway): scope answers to the question's subject on both answer prompts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Harden both answer system prompts so retrieved passages about a *different* subject (person / product / entity) than the question are not presented as the answer — the model must say the context lacks the answer instead. Applied to _ANSWER_SYSTEM_PROMPT (/v1/query) and INJECTION_RESISTANT_SYSTEM_PROMPT (the injection-resistant answer surface). Also gitignore .env.openai. Verified: ruff, ruff format, mypy --strict (gateway + injection), pytest (injection + gateway + red-team prompt-injection suite).
