Plaid — Bank Account Linking & Transaction Sync

Full Plaid integration with zero gems — plain Net::HTTP service module, Plaid Link frontend, cursor-based transactions/sync job, webhook-driven updates, a connection-health state machine for re-auth, and the hard-won fixes for the "two accounts at the same bank" data-crossing trap.
