The corpus

Real data, publicly redistributable, committed. Two volumes and one capture:

• bundles/bend-or/ — a city volume built from open data: the district survey, the national hydrography enrichment, the offline-rasterized basemap. It is the deepest pipeline output in the tree — multipart zones, described shapes, a national-layer join — and it reproduces byte-for-byte from its archive, which is what lets tests hold real output to exact expectations.
• bundles/mars/ — a NASA Trek volume: the sphere, three lenses, the WMTS quirks a planetary source brings. Public domain.
• translators/nasa-trek.doc.json — one real captured Trek document, so the translator's test parses what the source actually serves rather than only what we imagined it serves. nasa-trek.fixture.json is its summary.

Each bundle directory is a JSON extraction of one build: the manifest, each world's payload, text and unpacked locations, and a per-pyramid tile inventory carrying content and decoded-pixel digests. No rasters and no archives are committed — which is exactly enough to hold a reader to the format.

What may live here

Public provenance is the bar. A fixture captured from a commercial game, an installed library, or anything else that cannot be republished does not go here — it goes nowhere. Tests that need shapes the corpus lacks build them: synthetic bundles through the real writer (format/bundle's fixture builder), synthetic scenes through the render tests' model factories.

.gitattributes marks this whole tree -text: the files are compared as bytes, and no checkout may rewrite them.
