The incident set the stage for follow-on outages in March 2026 that cost an estimated 6.3 million orders, ultimately triggering a 90-day code safety reset across 335 critical Amazon systems. The root cause was an agent inheriting the launching engineer's full permissions with no identity boundary, no confirmation gate, and no scoped-access model.
