0. Registry Classification

• Family: Boundary Contract Coupling
• Treatment: Standalone / Canon-Aligned
• Status: draft
• Scope: Cross-Domain
• Primary U-Layers: TBD
• Operator Scaffold: TBD
• Primary Diagnostics: H, ι, Au, BΣ, K, R, 𝓓(t), τ_m

1. Purpose

This arc repairs extractive, coercive, invalid, or over-fused coupling.

Core restoration function:

TBD. State the canonical restoration function during editorial review.

2. Use Conditions

Use when:

• TBD. Add use conditions during editorial review.

Do not use when:

• TBD. Add contraindications during editorial review.

Preconditions:

• Stabilization can be established or is already present.
• Auditability can be preserved or restored.
• Required gates can be enforced.

3. Failure / Damage Signature

TBD. Map the pre-state across S during editorial review.

4. Restoration Objective

Restore coherence by reducing hidden debt and inversion, increasing auditability, repairing boundaries where relevant, and validating the result over time.

5. Operator Sequence

Λ reassessment
→ ⊗↓
→ BΣ↑
→ Π exit path
→ Σ post-exit immunity
→ ℛ

Sequence notes:

TBD. Clarify stage gates, repeatable steps, irreversible steps, and temporal validation requirements during editorial review.

6. Gates

TBD. Add required gate checks and failure rules during editorial review.

7. Diagnostics

Required diagnostic trends:

• H decreases
• ι decreases
• Au increases or remains adequate
• BΣ is restored or preserved
• R increases
• recurrence decreases

8. Anti-Patterns / False Restorations

TBD. Add named anti-pattern links and false restoration risks during editorial review.

9. Completion Criteria

d⊗/dt < 0
dBΣ/dt ≥ 0
K ↑
recapture ↓
H ↓

Completion requires temporal proof and must not depend on Φ recovery alone.

10. Cross-Links

TBD. Add related restoration arcs, failure modes, diagnostics, laws, and invariants during editorial review.

11. Domain Notes

TBD. Add domain cautions where this arc applies to AI, governance, biology, economy, CMS, or archetypal systems.
