When two views independently call UUID() for what should be the same session, you're not building a flow — you're building two parallel ledgers that can't see each other. Settlement looked for withdrawals under one ephemeral ID; the withdrawals were saved under another. The fix isn't more code, it's one canonical source of identity handed down from the parent. Any system that lets components mint their own identifiers for shared entities will eventually fail to settle against itself.
