HumanPersonaBase: Language-Agnostic Framework for AI Personality with Inner Shell Architecture

⚠️ WITHDRAWAL NOTICE (2026-03-29): The experimental design underlying this paper has a fundamental methodological flaw. The live validation (Section 4.4) claims that Inner Shell state injection changes LLM output, but the actual system prompts sent to the LLM were not disclosed, making the core claim unverifiable. The observed output differences may be attributable to trivially different prompt text rather than the Inner Shell Architecture itself. This paper is withdrawn pending complete experimental redesign with full prompt transparency. The framework and codebase remain available at https://github.com/RintaroMatsumoto/human-persona.
