Issue dossier
The official page frames GreyCTF Summit 2025 as a cybersecurity summit with talks, workshops, booths, and GreyCTF context, while the repository frames the artifact as the GreyCTF 2025 badge. This record treats it as a source-backed Singapore hacker-culture/security badge without overclaiming universal public distribution.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
