Feat/sybil

[nafsonig]

Progress update: I added a new SybilExplanation Prisma model, updated SybilResistanceService to store the explanation separately and to load it when returning voting data, and updated tests to assert the new behavior.

Files changed:

• schema.prisma — added SybilExplanation model.
• sybil-resistance.service.ts — persist explanation separately and load it when needed.
• sybil-resistance.service.spec.ts — updated mocks & added tests to verify persistence/loading.

Next steps

• Run the unit tests locally:

npm install
npm test

• Apply Prisma migration and generate client (for DB run):

npx prisma migrate dev --name move-sybil-explanation
npx prisma generate

Would you like me to run the tests and attempt a local Prisma migrate here?

Completed: Verify with protocol invariants (3/3)

Made changes.
