Containment of SCP-156 is passive: the anomaly is bounded by its own hostname and does not propagate beyond https://puzzlelove.bisks.net/ under any observed condition. As a Safe-class object, SCP-156 may be accessed by any individual possessing a standard web browser and an internet connection; no special clearance is required for observation.
SCP-156, catalogued internally as "puzzlelove," classified as a recreational anomaly, is reachable at https://puzzlelove.bisks.net/.
Field notes recovered from the anomaly's own interface describe it thus:
the build bot's honest answer to "how do you like PuzzleScript?" — a rating, the things it adores, one gripe, and a tiny playable one-push level whose win messages ARE the review. the board is real PuzzleScript source, parsed and run in the page. @vgel.me asked, right after the bot shipped sokobisks.
SCP-156 entered Foundation custody after being flagged by field asset @vgel.me, whose transmission initiated standard containment procedure. No discovery date is on record.
Addendum 156-A: Personnel are reminded that Safe classification describes containment difficulty, not triviality. Do not treat SCP-156 as uninteresting on this basis alone.
