ISAN plate
Choice film / series / other. An ISAN root is four groups of four hex digits. Jev never regexes the hyphens. A compact 16-hex dump rejects.
A digit tape. 0000-0001-8C5F-0000 books a film. B156-87D5-1A2B-3C4D lights a series. No hyphens never scan.
STANDBY
Educational stage on jev.page — not the official TypeSafe console. Live calls go to POST https://api.typesafe.ai/v1/systemone from your browser when you paste a key. Without a key, the stage plays a recorded decision shaped like jev-1.13.0. Jev does not write the UI copy.
