Printed exactly as supplied, in the order supplied, with no labels and no ranking between them. This site runs no checks against any of them. It publishes no uptime figure, no status light and no date of last checking, because it never looks. An address that opens is not by itself evidence of anything.
The catalogue
Forty two actions, each filed under the observer with the clearest view of it. This page carries the first fifteen, from the moment a connection starts to the moment an account exists.
How to read a card
The six slots are always in the same order and always mean the same thing, which makes cards comparable. Two cards can be laid side by side and the difference between them is a difference in the world, not a difference in how somebody chose to write them up.
The amber line under the title is the observer list. It is deliberately the most prominent thing on the page after the heading, because it is the answer to the question most readers actually came with. It names parties, not technologies. "Whoever runs the wifi" is a party. "Encryption" is not.
The section headed "what they learn" is written to be checkable. Where a card says a party learns a time, it means a time. Where it says a party learns a place, it means a place. Vague phrases like "your activity" or "your data" have been kept out of it on purpose, because they are the reason people cannot reason about this subject.
The section headed "what they do not learn" is the same length and is not a consolation prize. It is where a reader finds out that the thing they have been worrying about is held by somebody else entirely, or by nobody. Roughly half the corrections on this site live in that slot.
Under those two comes the numbered list of things that change the answer. The count is computed from the list itself, so the number on the card is the number of entries, and it moves when the list moves. Each entry says what it does and then says what it does not do, because a reducer that is described only by its benefits is a sales pitch.
The last line is short and always negative. It exists so that no card can be quoted as a promise.
The order
Cards run in observer order rather than in the order a person would do things, and that is intentional. A reader following a task list learns a sequence. A reader following an observer list learns a structure, and a structure survives the sequence changing.
If you would rather see the observers first and pick from there, the comparison page puts all seven in one table. Otherwise the run starts here and continues on page two and page three.
