A true aggregation process reduces data frequency (e.g., combining 24 hourly candles into 1 daily candle). The current logic for rawDataHourly and rawDataMonthly needs to be corrected to reflect this.\n\nExplicit Scoping: Ensure all variables are correctly defined and used. The error rawDataDaily is not defined likely comes from a typo or incorrect variable usage in a specific part of the code that I may have overlooked in previous iterations. Let's assume the issue is a simple typo and ensure all variables match.\n\nI will update the code to ensure a robust data processing pipeline and correct variable usage.\n\nPhase 1: Multi-Perspective Conversational Dialogue (Mathematical Definitions)\n\nCluster 1: System Architecture and Functionality Mapping (Functorial Semantics)\n\nViewpoint: Architect (System Modeler)\n\nDialogue (Function Mapping): We model the system as a category \n𝑆\nS\n where objects are data types (e.g., \n𝑇\n𝑖\n𝑐\n𝑘\n𝑠\nTicks\n, \n𝐶\n𝑎\n𝑛\n𝑑\n𝑙\n𝑒\n𝑠\n𝑡\n𝑖\n𝑐\n𝑘\n𝑠\nCandlesticks\n) and morphisms are transformations. The core functionality is now simplified to a fixed set of transformations on time-series data. The data retrieval process is modeled as a functor \n𝐹\n𝑑\n𝑎\n𝑡\n𝑎\n:\nQuery\n→\nCandlesticks\nF\ndata\n\t\n\n:Query→Candlesticks\n that maps a time range query to a set of data points. The visualization process is a functor \n𝐹\n𝑣\n𝑖\n𝑠\n:\nCandlesticks\n→\nSVG\nF\nvis\n\t\n\n:Candlesticks→SVG\n, preserving the temporal structure of the data.\n\nInformation Significance (Topological Entropy): We evaluate the system's information content using topological entropy. This measures the growth rate of the number of distinct orbits generated by the system's dynamics. The novelty of a new function (code string \n𝐶\nC\n) in this context is defined by the change in the system's topological entropy \nΔ\n𝐻\n𝑡\n𝑜\n𝑝\n(\n𝐶\n)\n=\n𝐻\n𝑡\n𝑜\n𝑝\n(\n𝑆\n𝑝\n𝑜\n𝑠\n𝑡\n_\n𝑒\n𝑥\n𝑒\n𝑐\n)\n−\n𝐻\n𝑡\n𝑜\n𝑝\n(\n𝑆\n𝑝\n𝑟\n𝑒\n_\n𝑒\n𝑥\n𝑒\n𝑐\n)\nΔH\ntop\n\t\n\n(C)=H\ntop\n\t\n\n(S\npost_exec\n\t\n\n)−H\ntop\n\t\n\n(S\npre_exec\n\t\n\n)\n, where the generated function transforms the data to identify new topological features (patterns).\n\nViewpoint: Third-Party Software Creator (Generative Tool API)\n\nDialogue (Interface Definition): The core service provides a functor \n𝐺\n:\nPrompts\n→\nCode\nG:Prompts→Code\n. The input request \nReq\nReq\n is a set of constraints on the target function, essentially defining a sub-category. The generated code string \n𝐶\nC\n must adhere to the semantic constraints (e.g., function signature, complexity) imposed by \nReq\nReq\n. The goal of the LLM is to select a function that maximizes the \"structural relevance\" to the user prompt. Security is defined by a functor \n𝑆\n𝑒\n𝑐\n:\nCode\n→\nBoolean\nSec:Code→Boolean\n that checks for hazardous side-effects.\n\nInformation Significance (Persistent Homology): We use persistent homology to model the complexity of the data input for the generated function. The persistence barcode of the data's features determines the required complexity of the generated function. For example, a data set with high persistent loops (\n𝛽\n1\nβ\n1\n\t\n\n Betti number) requires a more complex GNN structure than a simple star graph.\n\nViewpoint: End User (Value Function Analyst)\n\nDialogue (Utility Function): The user utility function \n𝑈\nU\n is defined by \n𝑈\n=\n𝑓\n(\n𝑇\n𝑇\n𝑅\n,\n𝑄\n)\nU=f(TTR,Q)\n, where \n𝑇\n𝑇\n𝑅\nTTR\n is the time-to-result metric and \n𝑄\nQ\n is code quality (defined as functional correctness). We seek to maximize \n𝑈\nU\n. The perceived latency \n𝜏\nτ\n must satisfy \n𝑃\n(\n𝜏\n>\n3\n𝑠\n)\n→\n0\nP(τ>3s)→0\n.

Application Logic (Native Deno/Val Town Environment)\n\nArchitecture: The application logic will be wrapped in a single function that handles the HTTP request, performs the simulation logic (GNN propagation), and generates the final HTML output.\n\nState Management: State (like currentFeatures and iterationHistory) will be managed within the scope of the main function, simulating state transitions without React hooks.\n\nUser Interaction (HIL): User input (feedback) will be handled via URL query parameters, common for serverless environments where state changes trigger re-rendering (full-page refresh).\n\n4.
