Findings and public status
Tests, limitations, and listing gaps
Neutral finding types replace a generic “bugs” bucket so affected versions and source scope remain visible.
test campaign resultnone reported in test campaign
Pro V&V anomaly status
The certification test report states that no anomalies occurred during the EVS 6.4.0.0 test campaign.
This is scoped to the submitted test campaign. It is not a claim that the system has no bugs or that no field incident can occur.

public documentation gapresolved details not enumerated
Deficiencies described but not itemized
The public report says encountered deficiencies were tracked and resolutions verified as needed, but section 3.3 does not itemize those deficiencies.
Do not infer the number, severity, affected component, or field impact of non-enumerated test deficiencies.

documented operational limitationprocedural controls recommended
Previously scanned ballot is not automatically distinguished
Washington's staff report states that EVS 6.4.0.0 cannot distinguish whether a ballot was previously scanned and describes ballot-handling and staffing controls recommended by ES&S.
This is an operational limitation and mitigation note, not evidence that duplicate scanning occurred in an election.
public listing statusnone listed on selected record
No advisory attachment listed on selected EAC record
The archived EAC EVS 6.4.0.0 record did not list an advisory attachment when retrieved on 2026-07-19.
This is a page-listing observation, not a claim that no advisories, bugs, vulnerabilities, service bulletins, or field incidents exist.
