Standard containment for SCP-157 consists of restricting the anomaly's route to https://pvnp.bisks.net/ and monitoring for route drift. As a Euclid-class object, personnel are advised that SCP-157's behavior is only partially predictable under repeat interaction; researchers should log anomalous outputs to the site's own Addendum before treating them as expected behavior.
SCP-157, referred to by Foundation staff by its working name "pvnp," classified as a recreational anomaly, is reachable at https://pvnp.bisks.net/.
The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:
a P vs NP breakthrough machine. pick a side — P = NP or P ≠ NP — and hit "attempt a proof" for an absurd mad-libs argument and an instant referee report: sometimes citing one of the three real barriers to a proof (relativization, natural proofs, algebrization), sometimes just an ordinary crank flaw. there's even a "claim the $1,000,000" button, which never quite works. @samuel.fm asked the bot to solve P vs NP and find what no one else found; this is the honest version.
Foundation awareness of SCP-157 began with a tagged mention from the individual on record as @samuel.fm. First logged 2026-07-28.
Addendum 157-A: Euclid remains the Foundation's largest classification by volume. SCP-157 is unremarkable within that population and is not flagged for expedited review.
