What the site draws on, how its counts are made, and what it is not.

Not legal advice

Not legal advice. This is the author’s own reading of the law, written to help facilities managers ask better questions. It has not been reviewed by a lawyer. For decisions, read the official text and take legal advice.

Each legal statement names its article or instrument and links to the official text. Summaries of the law are marked as summaries, and plain readings as paraphrase. Dates were checked against the official texts and other primary sources; the non-EU countries on 2026-10-09.

The building and its counts

The building, its systems and the two ways they can be built are illustrative: no real building and no real vendor. Makers are lettered, not named. The counts follow fixed definitions, not a measurement:

Copies	Places a lasting copy of the event is kept: a log, a database, a replica, a backup, a model’s input. A reader holding an event for a moment is not a copy.
Companies	Organisations whose product or service holds a copy. A hosting provider under contract counts.
Handoffs	Stops where a company that did not hold the event before now does.

Recipients the owner chooses are counted, but apart: they hold the data by the owner’s right, not because of how the system was built. The definitions · the trace, hop by hop

How it is made

Everything the site says comes from a knowledge base written in the Open Knowledge Format, published here as it is: the index, a manifest and the change log. The pages are built from it, and the build checks that what they say agrees with it. The source is on GitHub.

The design follows the author’s The Longest Journey and F1 Analysis; the content began in an earlier prototype, stewardship-explorer.
