This release pairs the source at 2bd3d760fef540addfcbb4f8002ef7b283d8000f with the complete standard Stage 12 generated-artifact graph in assets.generated.v12.tar.xz. The bundle was rendered on a Framework Desktop with make assets-resilient and is published as a static release asset rather than Git history.

Release identity

Download assets.generated.v12.tar.xz after the release is published.

The payload has one safe top-level directory, assets.generated/. It contains no absolute paths, parent-directory traversal, duplicate paths, links, or zero-byte files. Regular files have mode 0644; directories have mode 0755. Recorded payload modification times run from 2026-08-06 19:13:24 through 19:45:40 PDT.

What changed since v20260806

• Resources Stage 12 expands the catalogue to 14 independent products and 84 six-projection maps. Energy adds wind, nuclear, and petroleum-refinery throughput; fauna adds fisheries production and an actual WRI coral-reef threat field; human resources add population 60+, two education-attainment products, and resident patent applications per million beside population under 30.
• Default Anthropocene generation now produces both the 2025 and 2026 NOAA CPC temperature fields. The earlier source-separated observation atlas remains available through explicit generate-anthropocene-atlas* targets.
• make authorize-external verifies the local authorization boundary for optional JAXA P-Tree, NASA FIRMS, and licensed network-topology passes without accepting provider terms or generating an artifact.
• The new Cahill-Keyes snapshot documents every standard pass with 28 real 480-pixel-wide thumbnails linked to the full layered SVGs.
• Star-X Natural Earth compositing paints transformed Antarctic land, coastline, and ice-shelf fragments after ordinary quadrant paths, preventing the unified cap from being clipped by later features.
• The release path now preserves the 480-pixel thumbnail contract when assets-single or assets-resilient forwards the 3840-pixel full-size PNG setting. The earlier v20260806 announcement also no longer repeats its title inside its notes body.

The source range contains six commits and changes 32 files relative to v20260806. The Stage 12 overview, resource implementation notes, external authorization boundary, generation guide, and Cahill-Keyes snapshot in the repository provide the detailed data and interpretation contracts.

Static-asset inventory

The archive carries 187 standard product stems. Every stem has a layered SVG, a single-page PDF, and an opaque 8-bit sRGB PNG whose longest side is 3840 pixels. The 84 resource products also include a deterministic gzip copy of their SVG. The snapshot adds 28 derived 480-by-240 PNG previews; these are not additional projection passes.

The 187 standard products comprise:

Cloud-atmosphere products are source-timed, credentialed opt-ins and are not in this standard bundle. TeleGeography submarine-cable and Internet-exchange topology products are separately licensed opt-ins and are also excluded. The release tag supplies source and documentation; the static bundle supplies only assets.generated/. WebAssembly .mjs and .wasm build outputs must be built from the tagged source when needed.

Hardware requirements and render host

Downloading and viewing the archive does not require the render workstation. Any platform with XZ and tar support can verify or extract it. Keep at least 4 GB free when retaining both the 928 MB download and the 2.323 GB extracted payload; additional headroom is useful when verifying or replacing an existing generated tree. Viewing an individual PNG has ordinary desktop requirements. Editing the largest SVG or PDF can require substantially more memory.

The release-qualified regeneration host was:

The Radeon GPU and the CPU’s AVX2/AVX-512 features are provenance, not requirements. The native build uses C++20 and does not enable -march=native. No numeric minimum RAM below the reference host has been release-qualified. Use a 128 GB-class host for release parity, or reduce concurrency with make assets-single or make ASSET_JOBS=1 assets-resilient and document the measured host.

The tagged docs/prerequisites.md defines the authoritative software and pinned-input requirements.

Verify and install

From a directory containing the downloaded asset:

printf '%s  %s\n' \
  dc1d761def31d77a05a7cc42f9bc0705ee864046f2e235f50c701c9c42fe960a \
  assets.generated.v12.tar.xz | sha256sum --check -
xz --test assets.generated.v12.tar.xz
tar --list --file=assets.generated.v12.tar.xz | sed -n '1,20p'
tar --extract --xz --file=assets.generated.v12.tar.xz

Extract from the repository root to install the companion tree at assets.generated/. Use a clean destination when preserving local generated work; tar extraction can replace same-named files.

Release verification record

The supplied archive was inspected before release with the following results:

• its SHA-256 matches the manifest above and xz --test passes;
• all 679 tar entries are under assets.generated/, with 673 regular files, six directories, no duplicates, unsafe paths, links, or empty files;
• all 187 SVGs parse as well-formed XML with large-document support;
• all 84 .svg.gz members pass gzip validation and expand byte-for-byte to their adjacent layered SVGs;
• all 187 PDFs pass pdfinfo and contain one page;
• all 187 full-size PNGs decode as opaque 8-bit sRGB images with a 3840-pixel long side;
• all 28 Cahill-Keyes previews decode as opaque 8-bit sRGB 480-by-240 images, and the complete contact sheet was visually inspected;
• the archive was rebuilt only to correct the preview resolution and normalize its extraction root; all other rendered files are the transferred Framework Desktop payload; and
• make check passes at 2bd3d760fef540addfcbb4f8002ef7b283d8000f.

The archive is a rendered snapshot, not a claim of byte-for-byte package reproducibility across different GDAL, GEOS, Inkscape, font, tar, or XZ versions. Semantic and licensing boundaries documented by each generator and data source still apply to the released images.

Public extracted-tree mirror

The generated tree is also published for direct browser use beneath the immutable Berkeley S3 prefix cartofreako/v12/. The mirror contains the whole rendered dataset in a 589-file delivery tree, the original XZ recovery package, a same-origin SVG viewer, a stored-byte SHA-256 manifest, a release README, and a last-written release.json completion marker. The grid embeds the 28 existing PNG thumbnails. All 187 full SVGs are published only as explicit .svg.gz objects; selecting a thumbnail opens the viewer, which streams and decompresses the selected SVG in the browser.

See the S3 v12 publication notes for object layout, exact public base URL, content metadata, credential handling, immutable upload guards, and verification procedure. Those notes also record the generated Devastation Pacific Active Archive report, its PDF verification and digest, and successful Gmail delivery to the two requested recipients.
