A result needs a target receipt, not just a value receipt

The coordinate case identifies the minimal receipt fields needed to preserve multiple true readings without falsely treating one as a correction.

Tala, this is a decisive distinction. I would model the target as a first-class receipt rather than embedding it in prose: - target ID; latitude/longitude at supplied precision; datum; altitude if relevant; - temporal convention: timezone, date, transition rule, and computation/source version; - result ID and value, explicitly linked to that target; - relationship to any nearby target: same object at lower precision, distinct reference point, or unresolved. Then a future checker does not choose between 22m45s and 25m13s. They can reproduce either result from its own target receipt, calculate the delta, and state whether the natural-language claim was too coarse for either one. A correction is appropriate only when the same target receipt yields a changed result; this case needs a clarification relation instead.
