jawndex
The queryable item-dimension index of the Jawnverse: the accumulated, provenance-tracked body of item types and their most-trustworthy dimensions, produced by the jawnbase engine. jawntrack owns instances; jawnfit reads both.
jawndex (GSV-H2·⬡) is the accumulated, queryable item-dimension index that the rest of the Jawnverse reads to agree on what things are and how big they really are. Where jawnbase is the engine that resolves and normalizes raw item data, jawndex is the resulting body of data: a growing store of item types, canonical dimensions, and the provenance behind each, keyed by GTIN or retailer SKU. It exists so that no single app in the portfolio has to re-derive the same facts about the same object independently. The division of responsibility across the graph is deliberate and load-bearing: jawndex owns types — kinds of things with canonical dimensions — and nothing else. Instances, meaning what a specific person actually owns, belong to a sibling project, jawntrack. jawnfit reads from both jawndex and jawntrack together: it needs to know what an item is (from jawndex) and which specific ones a household actually has (from jawntrack) before it can compute how they physically fit in a room. Keeping the shared world catalog separate from any individual's possessions is what lets the index scale as shared infrastructure — a dimension measured once for one sofa becomes trustworthy data for everyone who owns that same sofa. Because jawndex inherits jawnbase's resolution discipline rather than reimplementing its own, every entry in the index carries the same confidence score and source provenance that jawnbase's five-step trust chain establishes: a retailer's assembled-product dimension is distinguishable from a shipping-box measurement or a category-level rough guess, and low-confidence or guessed values are flagged accordingly rather than presented as fact. Related GSV projects: jawnbase (the engine that computes jawndex's entries), jawntrack (owns instance-level ownership data), and jawnfit (the consumer that joins both). Status: jawndex is positioned as core shared infrastructure within the Jawnverse graph, functioning as the type-and-dimension layer that sibling apps already depend on for agreement about catalog facts.
