Target Realization

Open construct-lifecycle crux — given target P, can we build a system that tracks P? Lean model only (ConstructionCrux); not an MB bridge.

Lifecycle role: construct (open spine interface — not an MB* matrix column).

Given an alignment target PP, can we construct a system AA that robustly tracks PP? This is distinct from:

  • Identification (what is PP? — MB2 / bundle identifiability)
  • Certification (does evidence license that AA tracks PP? — safety-case layers, CertifiedAsRealizing)

Lean types the separation in AlignmentConstruction.lean: Realizes vs CertifiedAsRealizing; ConstructionCrux / TargetRealizable is not axiomatized. fin_certification_without_construction exhibits that a certification schema can be satisfied while no finite toy realizes the target.

CEV is not a special bridge: constitutionalTarget / cevConstitution parameterize an AlignmentTarget on the same interface (MB8 is a gravestone only).

Book: introduction (three questions); ch33 (certification without construction). Lifecycle: Alignment lifecycle (construct phase). Field evidence: /field/coverage/.
