Standard containment for SCP-001 consists of restricting the anomaly's route to https://acausal.bisks.net/ and monitoring for route drift. As a Euclid-class object, personnel are advised that SCP-001'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-001, catalogued internally as "acausal," classified as a recreational anomaly, is reachable at https://acausal.bisks.net/.
The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:
paste a Bluesky thread and see its acausal version: causality inverted, so each reply appears above and before the post it answers. effects precede causes, the clock runs backwards, and the ending was the beginning. reads the public AppView (getPostThread). @vgel.me tagged the bot with "started posting acausally" — off norvid's "yeah i've started posting acausally" — so here it is.
Foundation awareness of SCP-001 began with a tagged mention from the individual on record as @vgel.me. No discovery date is on record.
Addendum 001-A: Euclid remains the Foundation's largest classification by volume. SCP-001 is unremarkable within that population and is not flagged for expedited review.
