— Why We Still Do Not Control


📌 Introduction

aitl-physical-reference v1 is a board that deliberately stays at the point where
it looks like it could be controlled — but is not, yet.

This is not because it is incomplete.
It is a design decision.

Before introducing control,
there is still physical reality that must be fixed.
Version 1 exists to make that boundary explicit.


🔄 What Changed from v0 to v1

In v0, the following were fixed in the smallest possible form:

v1 takes exactly one step further.

It exposes a state that feels controllable,
while intentionally leaving it undefined.

That tension is the point of v1.


❓ Why We Still Do Not Add Control

PID, FSM, AI-based control —
all of them deal with how outputs should change.

But before that, the following must be fixed:

Control is a choice.
Physics is a precondition.

v1 chooses not to add control,
so that this precondition cannot be ignored.


1️⃣ Schematic (v1): Logic Is Exposed, Behavior Is Not Written

Schematic v1

Logical signals are, for the first time, explicitly routed outside.

However:

It allows the illusion of control,
but control itself does not yet exist.


2️⃣ PCB Layout (v1): Copper Quietly Restricts Freedom

PCB v1

Even as logic increases,
current still flows only on this copper.

None of these can be bypassed by control logic.

The degrees of freedom of control are silently constrained by physics.
This layout exists to make that visible.


3️⃣ 3D View (v1): The Object Exists, Control Does Not

3D v1

It has height.
It has touchable components.
It has measurable points.

And yet, this board
still does nothing.

Here, we deliberately stop the misconception that
“implemented” means “controllable.”


🧭 The True Nature of v1: A Boundary Definition Reference

aitl-physical-reference v1 is:

It is a reference that fixes the boundary between logic and physics.

This is the board that draws the line
before control is allowed to step in.


🧩 Position Within AITL

In AITL (Architecture for Integrated Technology Logic),
the layers are explicitly separated:

v1 belongs entirely to the lowest layer.
It is the reference point of the Physical layer.

Only after this layer is fixed
do higher-level control and reasoning gain meaning.


⏭️ What Comes Next

In v2, behavior will be introduced for the first time.

What comes first is:

Control that humans can fully explain


🧾 Summary

Control was not added because
there was still physics left to fix.

aitl-physical-reference v1 is
a design that deliberately pauses
in order to move forward correctly.

Before control,
physics must exist as it truly is.

v1 is the reference that marks that boundary.
