# AccountOperation.selectApprovals

Validates, deduplicates, and selects owner approvals for an operation.

The function retains one canonical approval per owner. It selects the smallest deterministic quorum by owner weight, then orders the selected approvals by owner address for serialization. The caller supplies the account and config; the chain validates their factory-derived identity.
