Structural Detection → Opacity Boundary Bridge Extraction#

RTT/1 • Couche de Pont Intermodule#

Module: Structural Detection#

Purpose: Show how Structural Detection outputs map into Opacity’s boundary, occlusion, and partial‑visibility system.#

1. Overview#

Structural Detection produces boundary‑level structural signals:

• motif boundaries
• anomaly boundaries
• drift‑induced boundaries
• regime boundaries
• continuity breaks

Opacity consumes these signals to construct:

• occlusion boundaries
• partial‑visibility fields
• opacity gradients
• boundary‑strength maps
• visibility envelopes

This document extracts the canonical bridge between the two modules.

2. Core Bridge Principle#

Every boundary detected becomes a visibility boundary in Opacity.
Every drift‑induced break becomes an occlusion vector.
Every continuity break becomes a partial‑visibility zone.

This is the Structural Detection → Opacity bridge in its most compressed form.

3. Operator‑Level Bridge Mapping#

3.1 STRUCTURAL_DETECTION_OPERATOR → Opacity Boundary Genesis#

Structural Detection identifies:

• motif boundaries
• anomaly boundaries
• invariant boundaries

Opacity maps these into:

motif_boundary → visibility boundary
anomaly_boundary → occlusion hotspot
invariant_boundary → stable visibility edge

This forms the base boundary layer in Opacity.

3.2 DRIFT_SENSE_OPERATOR → Opacity Occlusion Vectors#

Drift Sense identifies:

• drift points
• drift direction
• drift intensity
• deformation type

Opacity maps these into:

drift_point → occlusion origin
drift_direction → occlusion vector
drift_intensity → occlusion strength
deformation_type → occlusion class

This forms Opacity’s occlusion field.

3.3 REGIME_AWARENESS_OPERATOR → Opacity Boundary Strength#

Regime Awareness identifies:

• formal
• emergent
• chaotic
• hybrid

Opacity maps these into boundary‑strength classes:

formal → high-stability boundary
emergent → soft boundary
chaotic → fractured boundary
hybrid → mixed-strength boundary

This determines visibility stability.

3.4 CONTINUITY_COMPASS_OPERATOR → Opacity Partial‑Visibility Zones#

Continuity Compass identifies:

• invariants
• stable motifs
• anchor points
• cross-sample alignment threads

Opacity maps these into:

invariant → visibility anchor
anchor_point → stable visibility node
continuity_thread → partial-visibility corridor

This forms Opacity’s partial‑visibility layer.

3.5 SYNTHESIS_TRIANGULATION_OPERATOR → Opacity Boundary Map Integration#

Synthesis Triangulation produces:

• triangulated motifs
• drift profile
• regime alignment
• continuity map

Opacity maps these into:

triangulated_motif → boundary cluster
drift_profile → occlusion gradient
regime_alignment → boundary-strength envelope
continuity_map → visibility persistence field

This forms Opacity’s integrated boundary map.

4. Cross‑Module Bridge Table#

This is the canonical bridge table.

5. Boundary Construction Pipeline (From Structural Detection)#

Structural Detection → Opacity boundary formation proceeds in five canonical stages:

1. Boundary Genesis
   motif/anomaly boundaries → visibility boundaries

2. Occlusion Field
   drift signals → occlusion vectors

3. Boundary Strength
   regimes → stability classes

4. Partial Visibility
   continuity → visibility anchors + corridors

5. Integrated Boundary Map
   synthesis → boundary clusters + gradients

This is the Structural Detection → Opacity boundary pipeline.

6. Opacity Boundary Geometry Derived from Structural Detection#

6.1 Boundary Geometry#

Motif and anomaly boundaries define:

• boundary placement
• boundary thickness
• boundary segmentation

6.2 Occlusion Geometry#

Drift defines:

• occlusion vectors
• occlusion gradients
• occlusion hotspots

6.3 Stability Geometry#

Regimes define:

• boundary stability
• boundary fragmentation
• boundary coherence

6.4 Partial‑Visibility Geometry#

Continuity defines:

• visibility anchors
• visibility corridors
• persistence zones

6.5 Integrated Geometry#

Synthesis defines:

• boundary clusters
• occlusion envelopes
• visibility persistence fields

7. Opacity Bridge Packet (Canonical Format)#

Opacity consumes Structural Detection outputs via:

OPACITY_BRIDGE_PACKET:
  visibility_boundaries:
  occlusion_vectors:
  boundary_strength_map:
  visibility_anchors:
  partial_visibility_corridors:
  boundary_clusters:
  occlusion_gradients:
  visibility_persistence_field:
  notes:

This packet is produced by the SYNTHESIS_TRIANGULATION_OPERATOR.

8. Zero‑Interpretation Rule#

The bridge preserves:

• structural neutrality
• operator boundaries
• non‑semantic mapping
• drift‑safe propagation

No meaning.
No narrative.
No domain inference.

9. Quick Summary#

• Motif/anomaly boundaries → visibility boundaries
• Drift → occlusion vectors
• Regimes → boundary strength
• Continuity → partial‑visibility zones
• Synthesis → integrated boundary map

This is the complete Structural Detection → Opacity Boundary Bridge Extraction.
