From a5b259644c0b4a6c34293f75b417d3e5feb28ad3 Mon Sep 17 00:00:00 2001 From: pyros-projects Date: Tue, 25 Nov 2025 15:45:56 +0100 Subject: [PATCH 1/6] feat(evolve): Phase 1 - Foundation layer with AlphaEvolve history tracking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the foundation for wishful.evolve, an AlphaEvolve-style evolutionary code improvement feature. Key components: - EvolutionError: Rich exception with best_variant recovery - EvolutionHistory: Core tracking with get_context_for_llm() - VariantRecord/GenerationRecord: Data classes for evolution state The critical innovation is history-as-context: the LLM receives previous attempts sorted by fitness, enabling informed mutations. This is the AlphaEvolve paradigm from Google DeepMind.

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the core mutation infrastructure for evolutionary code improvement: - mutate_with_llm(): Core function that calls LLM with evolution context - _build_evolution_context(): THE KEY ALPHAEVOLVE MECHANISM - formats history into rich LLM prompt with current best, sorted history, and user guidance - get_function_source(): Extracts source from functions (__wishful_source__ first) - _truncate_source(): Prevents context overflow for large functions The context builder gives the LLM: - Current best implementation - Evolution history sorted by fitness (best first) - Failed attempts with error messages - User guidance/mutation prompts 16 new tests (33 total), all passing. πŸ€– Generated with [Claude
