Licences

This repository is not under a single licence. Three sets of terms apply to three kinds of thing, and some third-party material inside it is under neither because it was never ours to license.

Read this file before reusing anything. LICENSE at the root is the Apache-2.0 text; NOTICE carries the attributions those terms require.

Decided 2026-09-17 by the copyright holder (see NOTICE), who holds the copyright in the original work.

1. Code — Apache License 2.0

Copyright 2026 Alex Camilo. Full text in LICENSE, with the required attributions in NOTICE.

Path	What
packages/brain/, packages/feed/	the reference neural core, contracts, codec, fake sim
apps/stage/src/, apps/stage/tools/, apps/stage/tests/	the broadcast page
services/flysim/crates/	the Rust service, emulator wrapper, reward adapters
services/bridge/src/, services/bridge/tests/	the Twitch bridge
infra/	provisioning scripts, systemd units, host tooling, test suites
tools/	the dataset builder and repository tooling
build and config files at any level	package.json, Cargo.toml, tsconfig.json, and friends

You may use, modify and redistribute this code, commercially included, under the Apache-2.0 terms: keep the licence and copyright notices, pass on the NOTICE content, and state the files you changed. The licence includes an express patent grant from contributors and grants no trademark rights.

Excluded from this grant, because they are third-party material — see section 4: services/flysim/vendor/binjgb/, apps/stage/public/fonts/*.woff2, and the extracted symbol names and addresses in services/flysim/crates/flybrain-gb/src/pokemon_red/symbols.rs.

2. Documentation, on-screen copy and stage assets — CC BY 4.0

Copyright 2026 Alex Camilo, licensed under Creative Commons Attribution 4.0 International.

Path	What
docs/	the architecture tour, the binding contracts, the model and learning pages, the design notes, the limitations list
infra/docs/	runbooks, provisioning records, measurements, spike write-ups
README.md, CONTRIBUTING.md, ROM-POLICY.md, this file	root documents
apps/stage/mockups/	the review PNGs
apps/stage/public/fixtures/	the four recorded .flyfeed feed fixtures
on-screen copy	the caption bands, chip labels, panel headings and ticker strings the broadcast page displays

You may share and adapt these, commercially included, with attribution and an indication of any changes.

Two things worth stating so nobody has to guess:

• On-screen copy is text, but it lives inside source files. The strings the page displays are CC BY 4.0 as text; the .tsx and .rs files that contain them are Apache-2.0 as code. The same copyright holder grants both, so a reuser may rely on whichever fits what they are taking.
• The feed fixtures are synthetic. All four .flyfeed recordings in apps/stage/public/fixtures/ are generated by the fake simulator in packages/feed/src/fake/, not recorded from a run on the connectome. They carry no FlyWire-derived content and so are not bound by section 3.

3. The connectome artifacts — CC BY-NC 4.0, unchanged

data/fafb-v783/ — all twelve files.

These are not ours to relicense. They are artifacts derived from the FlyWire FAFB public Codex v783 exports, used under CC BY-NC 4.0, and they keep those terms for everyone downstream. Nothing in sections 1 or 2 loosens them.

The authoritative statement of source, modifications and required citations is data/fafb-v783/ATTRIBUTION.md. It must travel with any copy of these files. NOTICE reproduces it in summary; that file is the original.

What the licence asks of you if you redistribute them or an adaptation of them:

• keep the creator and attribution-party names, the copyright notice, the licence notice and the disclaimer notice;
• link to the material and to the licence;
• say that the material is modified, and keep the indication of previous modifications — these artifacts are already an adaptation, described in ATTRIBUTION.md;
• do not use them for commercial advantage or monetary compensation;
• do not add legal terms or technological measures that stop anyone else doing what the licence permits;
• do not imply endorsement by FlyWire or the cited authors.

The data and anything derived from it stay under CC BY-NC 4.0.

One derived artifact inside the repository inherits these terms: services/flysim/golden/real.flygold is a recorded run on this dataset. The other golden files are synthetic and are Apache-2.0 with the code.

4. Third-party material, under its own terms

What	Where	Terms
binjgb emulator core, vendored unmodified at c60e138	services/flysim/vendor/binjgb/	MIT, © 2016 Ben Smith — LICENSE, PROVENANCE.md there
Press Start 2P, Pixelify Sans, Silkscreen, VT323	apps/stage/public/fonts/	SIL OFL 1.1, each with its OFL-*.txt alongside
pret/pokered RAM symbol names and addresses at 0cd19d3	.../pokemon_red/symbols.rs	no upstream licence statement. Names and numeric addresses only; no assembly source, game code or game asset
npm and cargo dependencies	not redistributed here	their own; lightningcss is MPL-2.0 and caniuse-lite is CC-BY-4.0, both build-time

5. No game ROM

No Game Boy ROM, ROM fragment, save file, emulator save state or ripped game asset is in this repository, and none is distributed with it. See ROM-POLICY.md. "Pokémon" and "Super Mario Land" are trademarks of Nintendo, used here descriptively to say which adapter reads which game; no affiliation or endorsement is claimed, and no licence granted here extends to any third party's trademarks.
