UI/Logic Alignment (D-1)

Ticket #73: Aligning the User Interface with D-1 Data Logic
Type: Enhancement / Finishing
Affected Component: templates/dashboard.html, templates/titre_detail.html

1. Context and Strategic Objective

Following the pipeline refactoring to use a D-1 data retrieval logic, the user interface (frontend) was displaying ambiguous or misleading information. The objective was to restore consistency between the backend and the frontend to ensure that the user has a fair and accurate understanding of the displayed data, thereby preserving trust in the tool.

2. Investigation Process

The investigation was carried out in several stages to ensure that the interface accurately reflected the new data reality.

  1. File Localization: The investigation began by searching for the HTML template files. An initial hypothesis based on Flask conventions (code_source_simule/templates/) proved incorrect. A broader analysis of the project's file structure helped locate the correct directory at the root: templates/.

  2. File Analysis: The two main interface files, dashboard.html and titre_detail.html, were inspected.

  3. Identification of Anomalies: The audit revealed multiple terminological inconsistencies, remnants of the old logic. Terms like "Today's Variation," "Top Performers of the Day," and "Current Value" were in direct contradiction with the D-1 data now being displayed.

3. Root Cause Identified

The root cause was a desynchronization between the code and its representation. The user interface labels were static strings that had not been updated to reflect the profound change in the data retrieval logic. The interface was telling an outdated story.

4. Implemented Solution

The fix was surgical. Each ambiguous label was systematically replaced with a factual and precise description in both HTML files:

  • "Today's Variation" was replaced with "Variation (D-1)" or "Variation (Previous Day)".
  • "Top Performers of the Day" became "Top Performers (Previous Day)".
  • "Current Value" was corrected to "Last Close".

5. Justification and Benefits

This final intervention was non-negotiable. It ensures perfect consistency across the entire stack, from the code to the interface. The benefits are clear: - Clarity for the User: The user knows exactly what data they are viewing. - Increased Trust: A precise interface enhances the credibility and reliability of the tool. - Complete Finalization: The intervention closes the refactoring cycle by ensuring that the impact is managed at all levels, including the user experience.
