Complete procedures with a way back.

Build a bounded Responses API agent whose strict function calls are treated as proposals, whose deterministic state and policy select eligible tools, whose consequential actions require exact human approval, and whose adapters use durable idempotency, effect-aware retries, deadlines, safe outputs, correlated audit and full-bundle rollback.

Design, validate, evaluate and operate schema-constrained OpenAI responses without confusing valid JSON with factual truth or authorization.
