Surfaces
Operational boundaries of Beacon‑Core.
Fixed. Distinct. Non‑overlapping.
Structure expressed through separation.
Structural Invariant — Surfaces
Surfaces define fixed boundaries through which Beacon‑Core is presented. They are non‑interpretive and do not expose mechanisms.
Purpose
Surfaces define the boundaries through which Beacon‑Core is externally encountered. They articulate structure without interpretation or narrative.
This surface describes boundaries only and does not expose mechanisms.

Canonical Surfaces
Beacon‑Core defines three internal surfaces and three external surfaces. Each is structurally distinct and non‑overlapping.
- Input Surface — ingress boundary
- Shaping Surface — constraint boundary
- Output Surface — egress boundary
- Interpretive Surface (External) — external articulation
- Structural Surface (External) — external structure display
- Identity Surface (External) — system designation
Non‑Overlap
Each surface remains distinct.
No overlap or semantic inheritance occurs.
Surfaces retain independent structural definition.
Why Surfaces Exist
Surfaces maintain structural clarity by isolating boundaries and preserving separation between internal and external domains.
Canonical Statement
Surfaces define the operational geometry of Beacon‑Core. They are fixed, bounded, and structurally distinct.
