The corpus
Real data, publicly redistributable, committed. Two volumes and one capture:
bundles/— 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.bend-or/ bundles/— a NASA Trek volume: the sphere, three lenses, the WMTS quirks a planetary source brings. Public domain.mars/ translators/— 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.doc.json nasa-trek.fixture.jsonis 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/'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.
