Boundary Profiles — RTT/1

Regime Interlock Mapper (RIM) — Boundary Intelligence Layer#

Boundary profiles describe how regimes meet, transition, or constrain one another.
They are the structural backbone of RIM’s boundary‑level analysis and feed directly into:

• RIM‑Boundary
• RIM‑Detect
• RIM‑Map
• RIM‑Interlock
• RIM‑Resolve

Each profile defines a canonical boundary condition, its diagnostic markers, and example regime pairs.

1. Boundary Profile: Structural‑Constraint Boundary#

Definition#

A boundary where one regime imposes a structural constraint on another.

Diagnostic Markers#

• rigid structural dependency
• unidirectional constraint flow
• low entanglement
• high stability

Example Regime Pairs#

• R1 → R2 (conceptual constraint → computational structure)
• R2 → R3 (computational constraint → physical calibration)

RIM Output Pattern#

• interlock_type: boundary
• boundary_condition: structural-constraint
• interlock_strength: 0.70–0.85
• entanglement_score: 0.20–0.40

2. Boundary Profile: Gradient‑Alignment Boundary#

Definition#

A boundary where gradients in two regimes align (directionally or in magnitude).

Diagnostic Markers#

• parallel gradients
• directional coherence
• medium entanglement
• moderate stability

Example Regime Pairs#

• R2 ↔ R4 (computational gradient ↔ dimensional gradient)
• R1 ↔ R3 (conceptual gradient ↔ physical gradient)

RIM Output Pattern#

• interlock_type: boundary
• boundary_condition: gradient-alignment
• interlock_strength: 0.75–0.88
• entanglement_score: 0.25–0.45

3. Boundary Profile: Transition‑Boundary#

Definition#

A boundary where a regime transitions into another (e.g., abstraction → implementation).

Diagnostic Markers#

• clear transition point
• medium stability
• low entanglement
• boundary curvature present

Example Regime Pairs#

• R1 → R3 (abstract model → physical implementation)
• R2 → R4 (computational model → dimensional coherence)

RIM Output Pattern#

• interlock_type: boundary
• boundary_condition: transition
• interlock_strength: 0.60–0.75
• entanglement_score: 0.15–0.30

4. Boundary Profile: Drift‑Sensitivity Boundary#

Definition#

A boundary where drift in one regime increases sensitivity in another.

Diagnostic Markers#

• drift amplification
• instability ridge formation
• medium entanglement
• low stability

Example Regime Pairs#

• R2 ↔ R3 (computational drift ↔ physical drift sensitivity)
• R3 ↔ R4 (physical drift ↔ dimensional drift envelope)

RIM Output Pattern#

• interlock_type: boundary
• boundary_condition: drift-sensitivity
• interlock_strength: 0.72–0.84
• entanglement_score: 0.30–0.50

5. Boundary Profile: Coherence‑Threshold Boundary#

Definition#

A boundary where coherence must exceed a threshold for regimes to interact.

Diagnostic Markers#

• coherence gating
• threshold discontinuity
• high stability
• low drift

Example Regime Pairs#

• R1 ↔ R2 (conceptual coherence ↔ computational coherence)
• R2 ↔ R3 (computational coherence ↔ physical coherence)

RIM Output Pattern#

• interlock_type: boundary
• boundary_condition: coherence-threshold
• interlock_strength: 0.78–0.92
• entanglement_score: 0.20–0.35

6. Boundary Profile: Resonance‑Boundary#

Definition#

A boundary where resonance in one regime influences resonance in another.

Diagnostic Markers#

• resonance amplification
• resonance curvature
• high entanglement
• medium stability

Example Regime Pairs#

• R3 ↔ R4 (physical resonance ↔ dimensional resonance)
• R2 ↔ R4 (computational resonance ↔ dimensional resonance)

RIM Output Pattern#

• interlock_type: boundary
• boundary_condition: resonance
• interlock_strength: 0.80–0.95
• entanglement_score: 0.40–0.70
