Please report security issues privately through GitHub's Report a vulnerability flow rather than opening a public issue. You can expect an initial response within a few days.

Photon Ring is an unsafe-heavy, lock-free crate. In scope:

• Memory-safety or data-race bugs in the ring, seqlock protocol, or atomic-slots stripes.
• Soundness holes in the Pod bound or the derive macros (e.g. a safe API that admits a non-Pod type).
• Undefined behavior reproducible under Miri on a default build.

Note that default-features = false selects the older volatile slot implementation, which is a deliberate data race under the Rust abstract machine — correct on real hardware, but flagged by Miri. That specific, documented behavior is not a vulnerability; the default build is formally sound. Reports of additional soundness gaps are welcome.
