+
+GNPL is Lithoglyph’s narration and projection language: a way to
+express, compare, and project forensic narratives over audit histories,
+evidence transformations, claim paths, and counterfactual alternatives.
+Rather than treating meaning as a single static query result, GNPL is
+designed for plural interpretations across time: what is true
+synchronically at a given state, what becomes true or false
+diachronically across a history, and what could have held under
+alternative evidential or causal paths.
+
+The live source currently lives in
+[nextgen-databases/lithoglyph/gql-dt](https://github.com/hyperpolymath/nextgen-databases/tree/main/lithoglyph/gql-dt)
+and will be migrated into this repository. Until then, treat that
+location as canonical. (This repo reserves the name and records the
+intended home; see the owner’s notes for the extraction plan.)
