URL State Management

Current Status

URL state management is implemented in the current frontend.

The quiz now supports:

• Shareable URLs for in-progress quiz state
• Direct links to product detail views
• Browser refresh without losing the current route context
• Browser back/forward support
• Share buttons on results and product-detail views

Current URL Parameters

• b - accumulated bitwise state for the user selections
• q - current question key or results
• p - product code for direct product-detail views

Examples:

/quiz/?b=16401&q=results
/quiz/?p=404&b=16401
/quiz/product/404

What Is Implemented

Core State Handling

• accumulatedBitValue is tracked in the frontend
• BIT_DEFINITIONS constants are present in script.js
• product_bitwise.json is loaded during startup
• updateBitValue() updates the accumulated bitmask from answer filters
• updateURL() writes b and q params without reloading the page
• initFromURL() restores the app from query params or direct product routes
• restoreStateFromBitValue() rebuilds the key quiz selections from the bitmask
• startOver() clears the URL state

Product Deep Linking

• Product cards open detail views through showProductByCode()
• Product detail views push the selected product code into the URL
• Direct query-string product links are supported with ?p=<code>
• Direct Flask routes are supported with /quiz/product/<product_code>

Share and Navigation Support

• shareCurrentPage() copies the current URL to the clipboard when supported
• A notification helper is shown after successful copy
• Share buttons exist on results and product detail screens
• A popstate listener handles browser back/forward navigation

Implementation Notes

The current implementation restores the primary quiz state used by filtering:

• base type
• subtype
• material
• color

That is enough to reopen result sets and product-detail pages consistently.

Dimension data is still primarily driven by the current session flow rather than fully reconstructed from the URL alone.

Validation Checklist

• Bitwise data loads at startup
• URLs update as quiz answers are selected
• Results pages can be shared with b and q
• Product pages can be shared with p
• Browser refresh restores route context
• Browser back button is handled in code
• Browser forward button is handled in code
• Full manual regression testing across all quiz paths

Known Limits

• URL restoration is designed around the current bitwise filter model, not a complete replay of every form interaction.
• Conditional question metadata exists in the navigation data, but the frontend does not yet use a fully generic conditional-resolution engine.

Recommended Next Steps

1. Manually test refresh and back/forward behavior on all major quiz branches.
2. Extend restoration if dimension-specific deep linking becomes a requirement.
3. Finish generic conditional navigation so URL restoration and question skipping use the same rules.
