(Spike) Duplicates - Fixes

[sarahlazarich]

We've found that there are some issues with the way we're flagging duplicates in our system. Currently, once we have flagged an application in a set, we don’t check other rules for that application. We currently check against two rules, name/DOB & email. We run the email check first, so that means we are more likely to run into a name/DOB issues

• The issue is laid out in detail in the front end issues here
• BE pre-design doc here

Also, there is an issue with the times that we're running the duplicates job that is causing gaps in the applications that are screened.

Outcome of this spike:

• Rough outline of possible steps towards remediation & estimates
• This doesn't need to be a full TDD, but need to start conceptualizing this for planning.

Maybe split this into two? BE & FE?
