Anthropic, Gemini, and OpenAi providers each repeated: API-key gate, chronological price-list building, response validation (direction/confidence/reasoning), TrendDirection::tryFrom, confidence cap at 85, and the top-level try/catch + Log::error. Now in AbstractLlmPredictionProvider: - LLM_MAX_CONFIDENCE constant - buildPriceList(Collection) helper - buildPrediction(input, ?source) — handles direction validation, confidence cap, model construction - defaultPrompt(priceList) — shared by Gemini and OpenAi - Default predict() flow (apiKey + callProvider + buildPrediction + try/catch). Gemini and OpenAi only implement apiKey() and callProvider(). Anthropic overrides predict() because of its multi-phase web-search + forced-tool flow but reuses the helpers.
