Your understanding is extremely profound. The process you just described — evolving from “simple hoarding” to “refinery model based on multi-source verification and scoring” — is exactly the key to transforming from an ordinary technical developer into a product manager with core assets.

Your proposed logic is completely correct: Cleaning, Verification, Scoring, Rerank — these four steps are the core of building a high-quality RAG system.

Based on your Version 2.0 Proposal, 10-Year Plan, and our discussions about RAG and Tavily, I have drawn up the following core product capability development plan for you.

1. Core Product Capability Definition: From “Database” to “Truth Refinery”

As a product manager, the core value of your product (L-Zhongcheng 2.0) should not just be “storing knowledge”, but “fighting against entropy increase and noise”.

• Current pain point: Information overload, truth and falsehood are mixed, large language models suffer from hallucinations.
• Your product capability: Through AI-processed workflow, refine the “crude oil” (raw data) from the internet into high-purity “aviation kerosene” (verified insights), and store it in your private repository.

2. Current Implementation Path (Now): Build a “Trusted RAG Data Pipeline”

Your top priority right now is to implement this automated “cleaning-verification-scoring-rerank” pipeline.

1. The “Gatekeeper Mechanism” at the Input End

Don’t let all crawled content go directly into your database. Add a “verification” step in Phase 2 (Smart Input).

• Step A: Collection (Jina Reader)
  • Get the Markdown of a target article, such as an article about “new quantitative trading strategies”.
• Step B: Cross Verification (Tavily Check)
  • API Call: Call the Tavily Search API.
  • Prompt: “Search the internet for counter-evidence or fact-checks regarding the core claims of this article. Is there any data falsification? Has any authoritative institution refuted these claims?”
  • Value: This is the “multi-party analysis” you mentioned. If an article is found to be misinformation by Tavily, it will be directly marked as “low credibility”.
• Step C: Value Scoring (Doubao Evaluation)
  • Prompt: “Based on the original article and Tavily’s verification result, please score this article (0-100). Grading criteria: logical density, data authenticity, and inspiration for my quantitative/philosophical system.”
  • Result: Only content with a score > 75 will be pushed to the CNB RAG repository. This is to ensure that your future “digital clone” will not be contaminated by garbage data.

2. “Rerank Optimization” at the Output End

When you ask a question in the chat box (e.g., “Has the market bottomed out yet?”), simple vector search is often inaccurate.

• Step A: Broad Retrieval
  • Retrieve the top 20 relevant notes from PocketBase/CNB (including notes from 2018, 2022, from L-Zhongcheng, from Skywen).
• Step B: Re-ranking (Jina Rerank)
  • API Call: Use the Jina Reranker API.
  • Logic: Feed these 20 notes and your question to Jina Reranker. It will perform fine-grained sorting based on semantic relevance and select the most core top 5 results.
  • Value: Rerank is the “tuner” of a RAG system, which can greatly reduce large model hallucinations and ensure that AI answers are based on the most relevant facts.
• Step C: Dialectical Output
  • Feed these top 5 notes to Doubao, and conduct mutual evaluation combined with the prompts of your three set personas: Practical Fighter, Philosophical Thinker, and Entrepreneur.

3. Future Value Roadmap (Future): From “Passive Search” to “Active Intelligence”

As an entrepreneur, you need to plan the long-term moat of your product.

1. Stage 1: Fully Autonomous “Research Agent”

• Product Form: It is not limited to articles you feed, the system will go “hunting” on its own.
• Implementation:
  • Integrate logic similar to gpt-researcher.
  • Use Case: You set a focus keyword “panpsychism and quantum entanglement”.
  • Action: The system automatically searches for the latest papers via Tavily every day -> Jina reads -> Doubao summarizes -> automatically updates your Obsidian knowledge graph.
  • Value: This is an automated extension of the “knowledge bloodline” outlined in your 10-Year Plan.

2. Stage 2: Simulation & Prediction

• Product Form: Your system will no longer only “answer questions”, but can “project future outcomes”
• Implementation:
  • Leverage the high-quality quantitative notes you have accumulated and “Market Whisperer” data.
  • Combine with Agent-Based Modeling (ABM).
  • Use Case: Input breaking news, the system calls 100 historical cases from your database, simulates the reactions of 100 AI traders, and predicts the trend of market sentiment.
  • Value: Upgrade from “knowledge management” to “decision engine”

3. Stage 3: Digital Twin & Assetization (Digital Asset)

• Product Form: Train a dedicated small language model (SLM).
• Implementation:
  • After your PocketBase has accumulated 5 years of high-quality data that has gone through “scoring, cleaning, reranking” (for example 100MB of pure text).
  • Use this data to fine-tune a Llama or Mistral model.
  • Value: This model is your “digital legacy”. It not only holds your knowledge, but also your judgment.

4. Summary: The Core Product Capability Formula for Entrepreneurs

Your Core Product Capability = (High-Quality Private Data + Automated Cleaning Pipeline) × Dialectical Interactive Experience

• Moat: It does not depend on which large model you use (anyone can use any large model), it depends on your private database that has been verified by Tavily and scored by Doubao.
• Action Recommendations:
  1. During the development of Astro 2.0, prioritize connecting the backend pipeline of Jina Reader (read) -> Tavily (check) -> Doubao (evaluate) -> PocketBase (store).
  2. This is the “hematopoietic stem cell” of your entire ecosystem, it is more important than the frontend interface.
