Each obligation, and the artefact that answers it.
| Source | Obligation | What Laidline emits |
|---|---|---|
| EU AI Act Art. 50(2)EU Code of Practice, Measure 1.1 | Machine-readable marking: metadata and an imperceptible watermark | A C2PA manifest signed with your key and a keyed watermark on every image, audio file and video. Streamed speech (Pipecat, LiveKit) and long text carry the keyed watermark only, with no manifest |
| EU Code of Practice, Measure 2.1 | Detection free of charge for the public and authorities | /detect, free for everyone whatever the licence, with a public response tier |
| Cal. B&P §22757.3 | Latent disclosure: provider, system and version, time, unique identifier, whether the system created or altered the content; permanent or extraordinarily difficult to remove or tamper with | In image, audio files and video the manifest and its signing certificate carry a field for each item (the provider through the certificate subject; the time when timestamped per asset); the watermark carries issuer and asset and, with the default image scheme, reads back after re-encoding, a three-quarter centre crop and screenshots (the figures) |
| Cal. B&P §22757.2 | A free, public disclosure verification tool with upload or URL, and an API | The same endpoint takes an upload or text, and returns the result as JSON; laidline.com/verify takes image and audio uploads. It takes no URL |
| EU Code of Practice, Measure 3.4(c) | Interoperable detection by 2 Feb 2027 | C2PA manifests any validator reads; watermark formats published |
| EU Code of Practice, Measures 4.1, 4.2, 4.4 | Compliance process, testing, documentation on reasoned request | The signed evidence bundle: log, checkpoints, certificates, the filled-in texts, a standalone verifier |
