KCAE.USE:11 - SoTA-Echoing

The practice question is whether to precompute, inspect on demand or combine them. Current provider accounts support both just-in-time exploration and long-context/cached reading; the latter still has task-dependent retrieval limits. KCAE.Profiles:1 compares those mechanisms with persistent retrieval. This pattern adopts workload-specific comparison, while rejecting universal vendor or lexical-first ordering. C.11.DUA supplies the broader burden question; the domain addition is the lifecycle workload and source/data-flow contract. Reopen the choice when demand, source volatility, recipient effort or executor capability changes.
