DIE-01: Delegation Integrity Envelope (Private Demonstrator)

Constraint-first delegation architecture for micro-authority surfaces (inbox agents, email triage, attention delegation). Core principle: Delegation becomes defensible only when authority is bound below execution and inadmissible transitions are structurally unreachable. Key features:- Admissible State Transition Model (S0-S6)- Deterministic Halt Conditions- Human Sovereignty Clause (draft-only, no binding commitments)- Context Integrity Envelope- Drift Detection Scope: Demonstrator for selective institutional circulation. Non-disclosure posture: This document defines structural conditions only. Implementation mechanisms remain private by design. Relevance: Andrew Chen (a16z) inbox agent ($150k/year willingness-to-pay), enterprise delegation, executive decision rights.
