Changelog

Unreleased

Changed

• Optimized the HTML dashboard data flow by splitting board loading and task detail loading.
• Kept the public /api/tasks/* API unchanged.
• Added internal /ui_data/* routes for lightweight board data and on-demand task details.
• Updated the /stats page to load a lightweight board model first and fetch full task details only for the selected task.
• Hid internal UI routes from Swagger / OpenAPI documentation.
• Updated tests and project documentation to match the new dashboard behavior.

Why

• The previous dashboard rendered the full task payload for every card directly into the HTML.
• This caused unnecessary data transfer and made the page size grow linearly with the number of tasks.
• The change reduces the initial payload and loads detailed data only when it is actually needed.

Effect

• The /stats HTML response became nearly constant in size instead of growing with the full board.
• Embedded per-card task payloads were removed from the DOM.
• The dashboard now transfers less data on initial load and keeps full task details as a separate targeted request.
• Measured impact on a 1000-task dataset:
  • /stats HTML reduced from 632,377 B to 11,413 B
  • embedded task payload reduced from 250,800 B to 0 B
  • full board data moved into a lightweight JSON response (162,656 B)
  • selected task details are loaded separately in a small response (179 B)
