Eval Builder

First output: classify the gate and expose the smallest executable slice. Do not lead with a harness plan unless the user specifically asked to build or promote an evaluator or harness.

Current authority is core/eval, docs/specs/spec-eval.md, and dna/core/eval.dna.yaml. core/testing, lev pentagon, and core/daemon-pentagon are migration inputs, not target authority.

Current operating mode

Treat this global skill as the hand-authored evaluator UX. Do not assume the plugin eval-design.flow.yaml is operational enforcement: its promotion path currently declares commandless lev.validate nodes that warn/yolo-pass. Do not invoke or project that graph as proof until its deterministic validators are executable, fail closed, and terminate in a real core/eval decision.
