Cytoplex (CAP), in plain terms
[!NOTE]
This is the easy-read variant. The full spec overview is the source of truth: README.md. Edit there; this page links back.
One sentence
Cytoplex is the safety gate. It decides what Yar is allowed to do, keeps your private data on your device, and writes down every decision so it can be checked later.
Why it matters
Yar can suggest things. Cytoplex makes sure it can never act in an unsafe way.
No diagnosis. No treatment claims. No data leaving your device without your yes.
Every "yes" or "no" is logged in a tamper-evident trail.
The pieces (plain names)
| Piece | What it does |
|---|---|
| Directive | A request to do something ("save this", "send that"). |
| Guard | The bouncer. It checks each Directive and can say no. "No" always wins. |
| Refusal message | A clear reason when the Guard says no. |
| Audit chain | A locked logbook of every decision. |
| CAP-Lite / CAP-Med | Two strictness levels. Yar uses CAP-Lite. Clinics would use CAP-Med. |
How it connects to Yar
It is the boundary before the AI runs and before anything is written out.
It governs personas (a persona can never act like a doctor).
It governs sensors (each sensor needs your separate permission).
Glossary
CAP: Controller-Authority Protocol. The safety protocol. (Not "Cognitive Architecture" or "Communication Augmentation"; those are old mistakes.)
Cytoplex: the doc set and spec that defines CAP.
Deny-wins: if any check says no, the answer is no.
