KCAE.SOURCE:11 - SoTA-Echoing

The practice question is how to retrieve small passages without making them contextless. Anthropic’s 2024 Contextual Retrieval is a useful historical mechanism: attach context to chunks before indexing. This pattern adapts that idea by retaining generated context separately and exposing its source dependencies; it does not adopt the reported corpus-wide gains as a forecast. Full-section indexing is a simpler rival with greater per-hit reading cost. Reopen the unit design when an actual miss depends on omitted context or when expansion overwhelms the reader. NOT.5 supplies a fuller translation/loss method where notation changes; ordinary file parsing alone is not an A.6.3.RT semantic translation claim.
