Change what you vouched for, and everyone sees it.

The file is read at /.well-known/sebbi-source.json on the company's own domain. What is found is reported as found.

Every source being watched has kept its word since it was first read.

Each line is sealed in the block shown. Check the chain yourself, free. Machine-readable: /x/sourcewatch/log

What a company knew, and when, decides what it should have done. This writes a formal notice telling a company that a free, published way to check its AI inputs and records exists, names the rules that apply, and asks four questions with 28 days to answer. The wording and the date are sealed, so neither can be disputed later.

You send it yourself, from your own email. A company answers by any published method: it says how its records can be checked at /.well-known/independent-check.json on its own domain, and that answer is shown on its page.

Put the gate in front of your own AI so nothing unvouched gets in: the Input Gate, free for 7 days, then 50p per agent per month.

Not without it showing. A company that vouches for its data hosts the list on its own domain, so it could edit the list later. sebbi.pro Source Watch keeps the fingerprint of every source file each time it is read. When a file changes, the change is worked out line by line, sealed, timestamped into Bitcoin and shown in public: a label that now points at different data is marked SWAPPED, data taken off the list is marked WITHDRAWN, and a file that disappears is marked FILE GONE. The Input Gate refuses data its source has withdrawn.

Write to it, and seal what you wrote. At sebbi.pro/source-watch you type the supplier's web address and get a formal Notice of an Available Method: it tells the company that a free, published way to check AI inputs and records exists, names the rules that measure conduct against what can reasonably be done, and asks four questions with 28 days to answer. The wording and date are sealed and timestamped into Bitcoin. You send it from your own email. From that day the company cannot say it was not told.

Because what a company knew, and when, decides what it should have done. Data protection law asks for every reasonable step and for measures that take account of the state of the art; the EU AI Act asks where data came from. A notice that can be proved to the day removes the answer 'we were not aware a check was possible'.
