MaleCNS v1.0 connectome — CC BY 4.0

Janelia Research Campus / FlyEM, male Drosophila melanogaster central nervous system connectome, v1.0 (165,122 neurons, 25,563,197 traced connections).

Used for: the graph itself (data/graph-traced-v1/), neuron metadata, and the skeletons and neuropil meshes rendered by the web app (web/public/brain/, produced by T07). web/public/brain/manifest.json records every source URL and SHA-256 next to the files.

CC BY 4.0 requires attribution wherever the data or anything derived from it is shown. The web app and the docs site must carry the credit, and downloaded artefacts keep their source URLs and checksums in the manifest next to them.

flyhard — MIT

https://github.com/MarkUnthank/flyhard by Mark Unthank. The same connectome trained to steer a car in CARLA.

Copied or ported here: scripts/acquire_connectome.py, scripts/prepare_graph.py, src/flyhard/connectome.py (SparseConnectome), scripts/acquire_cns_geometry.py, scripts/cns_view.py, benchmark_core.py.

MIT requires the copyright notice and licence text to travel with the copied source; each ported file keeps a header saying where it came from. Vendored so far: brain/data/acquire_connectome.py, brain/data/prepare_graph.py (T02), brain/connectome.py (SparseConnectome, vendored at T03 because the GPU benchmark needs it; it is also T05's first bullet), brain/benchmark.py (from scripts/benchmark_core.py, T03) and brain/geometry.py (from scripts/acquire_cns_geometry.py, T07 — the fetch and decode machinery is flyhard's, the selection, contraction and output format are ours) — both byte-identical to upstream apart from the attribution header, and exempted from ruff in pyproject.toml so they stay diffable against flyhard.

FlyGym / NeuroMechFly — Apache 2.0

https://github.com/NeLy-EPFL/flygym. Not used. The plan was to take the NeuroMechFly mesh for the fly-on-a-laptop scene, but FlyGym ships it as a MuJoCo model whose data files are not fetchable from the paths in its docs, and converting plus rigging it would cost more than it returns at 372 px on a stream. T11 permits a stylised fly, so web/src/rig.ts builds one in code. Nothing from FlyGym is vendored; this entry stays as a record of the decision.

Entries are added as each task actually vendors something; a file that copies third-party code is not merged until it is listed here.
