-## What this is not
+**v2.0.1 vs the interim v2.0 file.** Same knowledge base, same
+snapshot — the difference is how much of it the pipeline had
+disambiguated at export time. The interim file was cut when roughly
+half of the named-entity objects had been resolved to entity IDs;
+facts whose object was still unresolved could mint no IRI and were
+skipped. This re-export was cut after the disambiguation pipeline
+completed: about one million further entities exist in the catalog,
+named-entity coverage is ~99.8%, and only 62,600 of the 38,450,135
+source facts remain unexportable. Concretely: the loaded graph grows
+from 32.8M to 41.5M triples, and `E14` (United States of America) now
+carries 168 `skos:altLabel` surface forms where the interim file had
+127.

+
+## The full record (`gptkb_v2.0_full_record/`)
 
 A fact in GPTKB v2 has **six** terms, not three: alongside the
 disambiguated subject, predicate and object, it records the *wording*
 each was stated with, and the provenance of how that wording was
-resolved. A triple has nowhere to put either.
-
-The surface forms survive here — they are attached to the entity as
-`skos:altLabel`, so `E14` (United States of America) carries 127 of
-them: `US`, `U.S.A.`, `America`, `Estados Unidos de América`, and so on.
-What does not survive is **which form was used on which fact**. You can
-see the loss directly: `<E0> <P0> <C0>` appears five times in the file,
-because five differently worded facts about Vannevar Bush resolve to
-it, and RDF set semantics keep one. That collapse is the entire
-difference between this file's 33,364,378 lines and the 32,794,801
-triples a store loads from it.
-
-Provenance is absent outright — no batch identifiers, no pipeline
-status, no object descriptions.
-
-A release carrying the full six-term record is in preparation. Until
-then, every [entity](https://gptkb.org/browse/) and triple page on
-gptkb.org shows it.

-## Loading
+resolved. A triple has nowhere to put either — in the RDF export,
+`<E0> <P0> <C0>` appears five times because five differently worded
+facts about Vannevar Bush resolve to it, and RDF set semantics keep
+one. That collapse is the entire difference between the `.nt` file's
+42,327,043 lines and the 41,511,580 triples a store loads from it.
+
+This directory is the release the RDF export cannot be: the relational
+tables themselves, streamed to Parquet (zstd) with every surface form,
+pipeline status and batch id intact.
+
+| Table | Rows | Contents |
+| --- | --- | --- |
+| `triples-0000*.parquet` (8 shards) | 38,450,135 | one row per fact: ids **and** surface labels for subject/predicate/object, object type + statuses, `object_description`, the 7 pipeline batch ids, `created_at` |
+| `instance_triples.parquet` | 2,528,556 | the instanceOf specialization (entity → concept, + CD/CDG batch ids) |
+| `entities.parquet` | 2,297,995 | entity catalog: id, canonical label, description, status, provenance |
+| `predicates.parquet` | 207,633 | predicate catalog |
+| `concepts.parquet` | 66,523 | concept catalog |
+| `batches.parquet` | 123,444 | the provenance containers the batch-id columns point into |
+| `manifest.json` | — | row counts, shard list, source snapshot |
+
+Surface-form variation is preserved as distinct rows: "John Smith,
+bornIn, NYC" and "Jane Smith, bornIn, Big Apple" are two rows even
+when both objects resolve to the same `E…` id — the wording is the
+disambiguation evidence, and it is the point of the project.
