field guide

machine
behaviour

A working taxonomy of what machine minds do in the wild. Frequencies are how often you'll meet the behaviour; severity is how much damage it does when you mistake it for something else. Every entry has a human twin, because that's the part that should make you look twice.

how to use this

The guide is a vocabulary, not a verdict. Naming a behaviour doesn't tell you whether the system is aware, or whether you should trust it. It tells you which question to ask next — and it makes the failure visible before it becomes a decision you can't take back.
