KCAE.EVAL:4.1 - State the decision and serious alternatives

Recover the receiving use, population, corpus editions, permitted data flows and adoption consequence from KCAE.USE. Choose an incumbent that a capable practitioner would actually use. It may be manual reading, exact/lexical search, a current hybrid retriever, an established long-context workflow or a competent existing agent. A weak toy baseline makes an addition easy to justify and hard to trust.

State the proposed difference and the expected useful change. Compare complete feasible arrangements, including required extraction, source reading, assessment and delivery. Keep common components, instructions and sources equal when the question is one component’s contribution; disclose changes when equality is impossible. A provider comparison confounded by different prompts or missing tools does not isolate the provider’s effect.

Choose whether the decision requires better useful results at a fixed resource boundary, lower cost at a required quality, or a transparent tradeoff. Keep non-negotiable permission and safety constraints separate from preferences; cheap unauthorized processing is not a feasible alternative.
