Add Boundary Calculus evidence envelope integration

Purpose

Define the AgentPlane evidence envelope emitted when agents use the Boundary Calculus claim discipline.

File to add

docs/integrations/boundary-calculus-evidence-envelope.md

Minimum envelope

The run evidence should include:

• claim_id
• claim_status
• local_model
• boundary_or_interface
• non_claims
• evidence_refs
• promotion_gate
• policy_result

Policy hooks

Warn or block when:

• no claim_status is present;
• claim_status == metaphor and load_bearing != false;
• a security escalation lacks denominator discipline;
• a claim is promoted without a gate;
• attribution appears without discriminating evidence.

Boundary

AgentPlane emits evidence. SocioSphere owns the standard and promotion/demotion controller.
