Overview

• Registered representatives from Congress, all political parties, the Public Prosecutor’s Office, the OAB, the Federal Police and universities can inspect the code.
• Inspection is conducted on individual TSE workstations inside a secured room in Brasília, by appointment, with no personal electronic devices allowed.
• The audit calendar includes the Public Security Test in November 2025, confirmation tests in March 2026, system signing and sealing in August, and media generation and machine preparation in September.
• Officials said every operation in the sealed systems is mirrored to a monitoring environment so authorized observers can track changes until digital signing.
• Opening the code one year ahead continues a transparency policy adopted in 2022, replacing the previous six‑month window.
