System Map

1. Domains (Co‑Present)

BeaconCore consists of three domains:

Compute Domain
probabilistic, non‑authoritative, unsealed.

Surface Domain
deterministic, constraint‑bound, invariant‑preserving.

Record Domain
immutable, append‑only, non‑interpretive.

These domains are co‑present.
No domain precedes, follows, or governs another.

2. Relations (Non‑Directional)

Domain relations are non‑directional and non‑sequential.
No pipeline. No flow.

Placement, not transformation.

3. Surfaces (Placed, Not Sequenced)

Surfaces exist within the Surface Domain:

Input — ingress boundary.
Shaping — constraint boundary.
Output — egress boundary.

Surfaces are co‑present and spatially defined.
They do not form a pipeline.

4. Invariant Field (Spanning)

The invariant field spans all domains:

single role
bounded
deterministic
drift‑free

The field is global and always present.

5. Mechanism Field (Symmetric)

The mechanism field is symmetric across surfaces:

role boundaries
surface boundaries
semantic exclusion
determinism
drift prevention
state isolation

Mechanisms are persistent, not triggered.

6. Execution Plane (Neutral)

Execution occurs on a neutral plane:

stateless
repeatable
non‑interpretive

Identical inputs → identical outputs.

7. Envelope (Sealed)

The envelope defines system boundaries:

no external semantics
no external hierarchy
no external causality
no external narrative
no external adaptation

The envelope remains sealed.

8. Geometry Compression

Three domains — co‑present.
Three surfaces — placed.
Two fields — spanning and symmetric.
One plane — neutral.
One envelope — sealed.

This is the BeaconCore system geometry.
