The evidence-basis companion to the executive capability brief. Every capability labeled by readiness. Every claim traceable to a source. Every boundary named before a CISO asks.
AI systems, agents, tools, MCP servers, APIs, cloud resources. Ownership, environment, evidence modes.
Five evidence planes. DAI orthogonal comparison. Deterministic dispositions. Per-analyzer participation.
Human decisions, receipts, runtime monitoring, drift signals, response, verification.
The five planes are independent assertions. HAIEC does not require them to be supplied in order, and does not require all five to reach a finding. A single-plane evaluation is valid — it just names fewer established facts.
