Reviewed 2026-10-04 against the exact upstream revisions below. Upstream repositories were inspected outside this worktree; only the small adaptations identified here were imported. Original adapter/UI code is distinct from the upstream projects and is not endorsed by their authors.
| Upstream | Revision | License | Use in v0 |
| --- | --- | --- | --- |
| [supertestnet/testnet_generator](https://github.com/supertestnet/testnet_generator/tree/498be4cc775ef18e7ff17357d007918518f47b98) | `498be4cc775ef18e7ff17357d007918518f47b98` | CC0-1.0 | `getVin`/`getVout` object helpers from `index.html` adapted into `src/upstream/primitives.js`; converted to ES exports, explicit scripts, explicit final sequence. Inspiration for browser-owned UTXO chain, immediate 50-coin reward, button mining and integrated explorer. The upstream consensus/Script engine and relay system are **not** imported. |
| [supertestnet/inscriptions-online](https://github.com/supertestnet/inscriptions-online/tree/470b8bdf29ead319cff9dc119a005cbf58ee598c) | `470b8bdf29ead319cff9dc119a005cbf58ee598c` | CC0-1.0 | `index.html` ord envelope array adapted in `src/adapters/inscription.js`. Modern tapscript API, locally extended with MIME/byte payloads, explicit data-push encoding, 16 KiB cap, tag-3 parent serialization, parent-preserving child reveals and repeated tag-5 CBOR metadata fields. Single commit/reveal, same-wallet destination, no external broadcast or fee services. These extensions and the safe preview UI are original local adapter code. |
| [supertestnet/vanilla-js-browser-wallet](https://github.com/supertestnet/vanilla-js-browser-wallet/tree/19ae5097f4645bf5b1103a39abc04155a8b072fc) | `19ae5097f4645bf5b1103a39abc04155a8b072fc` | CC0-1.0 | Conceptual inspiration for minimal vanilla-JS wallet and local signing. No copied implementation. |
| [supertestnet/node_faker](https://github.com/supertestnet/node_faker/tree/2fae6056a7e93322a00a4150468934542ddc937d) | `2fae6056a7e93322a00a4150468934542ddc937d` | CC0-1.0 | Evaluated, **not imported**: its bitcoind-like API obtains data through Electrum connections. That introduces an unnecessary external backend for the self-contained v0. `LocalRPC` is a new, intentionally partial in-process read facade, not a claim of node_faker compatibility. |
The upstream CC0 legal text is retained unchanged at [`public/licenses/supertestnet-CC0.txt`](public/licenses/supertestnet-CC0.txt). Source comments identify the exact adapted code and revisions.
Runtime dependencies are pinned in `package.json` and `package-lock.json`:
- **@cmdcode/tapscript 1.5.3**, Christopher Scott, [upstream](https://github.com/cmdruid/tapscript), CC-BY-1.0. Used for transaction encoding, signing/verification, Taproot commitments and addresses, and the BIP-143 digests and signatures of SegWit payments. Installed package license retained unchanged at [`public/licenses/tapscript.txt`](public/licenses/tapscript.txt). Library source is unmodified; Vite bundles/minifies it for the browser.
- **@noble/curves 1.9.7**, Paul Miller and contributors, [upstream](https://github.com/paulmillr/noble-curves), MIT. Used for key generation/validation and public keys, and to verify the low-S DER signatures of SegWit payments: secp256k1 for chain and nostr keys, Ed25519 and X25519 for lineage's leaves. License retained at [`public/licenses/noble-curves.txt`](public/licenses/noble-curves.txt).
- **@noble/hashes 1.8.0**, Paul Miller and contributors, [upstream](https://github.com/paulmillr/noble-hashes), MIT. Used for synthetic block hashes, BIP-85's HMAC, the leaves' HKDF-SHA256 and the RIPEMD-160 of P2WPKH key hashes. License retained at [`public/licenses/noble-hashes.txt`](public/licenses/noble-hashes.txt).
- **@scure/base 1.2.6**, Paul Miller, [upstream](https://github.com/paulmillr/scure-base), MIT. Used for bech32 npubs and base64 leaf keys. License retained at [`public/licenses/scure-base.txt`](public/licenses/scure-base.txt).
- **@scure/bip32 1.7.0**, Patricio Palladino and Paul Miller, [upstream](https://github.com/paulmillr/scure-bip32), MIT. Used for HD derivation under the BIP-85, BIP-86, BIP-84 and NIP-06 paths. License retained at [`public/licenses/scure-bip32.txt`](public/licenses/scure-bip32.txt).
- **@scure/bip39 1.6.0**, Patricio Palladino and Paul Miller, [upstream](https://github.com/paulmillr/scure-bip39), MIT. Used for the 24-word lab roots and their seeds. License retained at [`public/licenses/scure-bip39.txt`](public/licenses/scure-bip39.txt).
Two local changes to the engine, both original code in `src/adapters/chain.js`, tested in `tests/money.test.js`, with Super Testnet's tests (`tests/adapters.test.js`) passing unchanged. Orgchain v1.5: the chain also accepts native SegWit (P2WPKH) outputs and SIGHASH_ALL P2WPKH spends, verified per BIP-143, so lineage accounts can hold and send test BTC at their BIP-84 addresses; everything about inscriptions stays Taproot-only. Orgchain v1.6: a coinbase may split the block reward across up to 64 outputs (`mineTo`; `mine` still pays one script), so one beat can pay several holdings.
Vite and Playwright are build/test dependencies, not runtime network services. Their installed package notices remain in the locked dependency installation. No unlicensed upstream code was copied.
The bounded JSON/CBOR codec, byte-derived MetadataIndex, trusted event-counter reducer, local API facade and persisted auto-miner schedule are original adapter code. Metadata encoding and endpoint naming were checked against the [Ordinals metadata](https://docs.ordinals.com/inscriptions/metadata.html) and [endpoint](https://docs.ordinals.com/inscriptions/recursion.html) references; no ord source code was copied.
