- scripts/lib/btc-htlc.mjs — P2WSH HTLC mirroring AtomicSwapHTLC.cash (same SHA256
hashlock, same claim/refund split, signet via esplora). Not yet run.
- scripts/btc-signet-setup.mjs — generate/show the gitignored signet funding key.
- .gitignore — ignore .btc-*.json (signet testnet keys).
Deps (bitcoinjs-lib, ecpair, tiny-secp256k1) intentionally left in package.json's
working tree, not committed — package.json carries an unrelated uncommitted line from
another session (chipnet:dashboard); same reason a71841f kept it out.
