# Implementation Flaw

A defect in implemented logic (logic, parsing, memory handling, resource handling) enabling unintended behavior when triggered — whether that logic is realized in application source code, firmware, microcode, or hardware description logic (substrate-neutral per R-SUBSTRATE). Implementation flaws are exploited by `#2 Exploiting Server` (server-role) or `#3 Exploiting Client` (client-role).
