BL-DUAL

Bottom-Left Duality

Class: Matter

Domain: EMS Semaphore

Function: Distinguishes machine geometry from expressive posture prior to action.

1. The Two Bottom-Lefts

BLᴹ — Machine Bottom-Left

  • GUI-defined coordinate.

  • Device-contingent.

  • Ephemeral.

  • Orientational only.

  • No authority over posture.

BLᴱ — Expressive Bottom-Left

  • Constitutional posture of admissibility.

  • User-anchored.

  • Portable across surfaces.

  • Governs stance.

  • Supersedes geometry.

2. Matter Rule

BLᴱ is authoritative.

BLᴹ is informational.

Geometry may assist orientation.

It may not determine stance.

3. Invariant

“Meet me at the bottom-left.”

Interpretation:

  • “Meet” → align orientation.

  • “Bottom-left” → BLᴱ unless explicitly constrained to geometry.

  • Device location is irrelevant.

4. Binding Condition

When BLᴹ and BLᴱ diverge,

posture prevails over placement.
