Summary

Map events to an attribute flag for selectPlacements

Testing Plan

• Use a sample app and map custom events to an attribute flag using the mParticle UI
• Fire the mapped event using the sample app
• Verify that the selectPlacement call is made with the attribute flag
• Restart your browser and verify that values persist
• End your session and verify that the values have cleared

I'm still unclear about the meaning of this test. what about a stringified number is being tested? saw that you resolved the original comment but didn't see any changes

[alexs-mparticle]

The purpose of this test is to verify that if a setting string is parsed, the string hashes in the jsmap and map properties are not converted to numbers, but remain as strings.

For example, "jsmap":"-1484452948" should be come jsmap: '-1484452948' (sting) and not -1484452948 (number)

Pull Request Overview

This PR adds functionality to map events to attribute flags for the selectPlacements method in the Rokt forwarder. When configured events are fired, they set local session attributes that are then included in placement selection calls.

Key changes:

• Added event mapping configuration parsing and lookup generation
• Implemented event processing to set local session attributes for mapped events
• Enhanced selectPlacements to include local session attributes in the request
