   Project mention: A rulebook of how money code breaks, and an agent that refutes its own findings | dev.to | 2026-07-12

   The read, the guard, and the write are not serialized. Under the default READ COMMITTED isolation, two concurrent captures of a 100 authorization both read captured = 0, both see 100 remaining, both pass the guard, and both insert. Result: 200 captured against a 100 authorization. There is no row lock, no version check, and no unique constraint to catch it. The same shape appears in refunds and in two promotion-budget counters. The gateway does not save you: the bundled Stripe provider swallows the already-captured error, so both capture rows persist, and each refund row carries its own idempotency key, so stripe.refunds.create moves real money twice. I filed the cluster upstream with a failing test that drops straight into Medusa's own concurrency test block; it is filed, not yet triaged, so judge it by the test: https://github.com/medusajs/medusa/issues/16012
