What it is
Tessera is a structured diagnostic. It names what is driving what across a whole life, and what to look at first.
No person reads your journal. That is by design.
It is why you can write what you might never say to someone sitting across from you. It is why all of the five territories can be held together - consistently, completely, and without a human filtering them through their own day.
What it is not
Therapy asks what happened to you. A doctor asks what is wrong with you. A test asks what type you are. A coach asks what you will do by Tuesday. An app asks how you slept.
Tessera asks what is driving what.
Not a type you take to dinner. Not a score. Not a thread that wants you back tomorrow.
If you need a clinician, this is a poor substitute. It will lose to a ring on last night and to a lab on the blood. Those measure. This places the measurements next to the rest of a life and asks what is driving what.
The body is read before exhaustion is allowed to look like character.
