-- [`07-open-channel-with-external-funding.bru`](tests/bruno/e2e/external-funding-open/07-open-channel-with-external-funding.bru): the main entry point; defines `funding_amount`, injects node2's funding/shutdown script, and captures the unsigned funding tx plus channel id.
-- [`08-sign-external-funding-tx.bru`](tests/bruno/e2e/external-funding-open/08-sign-external-funding-tx.bru): signs the unsigned funding tx with `EXTERNAL_FUNDING_PRIVKEY`.
-- [`09-submit-signed-funding-tx.bru`](tests/bruno/e2e/external-funding-open/09-submit-signed-funding-tx.bru): submits the signed funding tx and records the on-chain funding tx hash.
-- [`11-wait-channel-ready.bru`](tests/bruno/e2e/external-funding-open/11-wait-channel-ready.bru): the ready-state polling logic after funding submission.
-- [`15-shutdown-channel-from-node1.bru`](tests/bruno/e2e/external-funding-open/15-shutdown-channel-from-node1.bru): starts cooperative shutdown using node2's close script.
-- [`17-wait-channel-closed-and-capture-shutdown-tx.bru`](tests/bruno/e2e/external-funding-open/17-wait-channel-closed-and-capture-shutdown-tx.bru): the closed-state polling logic and shutdown tx capture.
-- [`18-inspect-shutdown-tx.bru`](tests/bruno/e2e/external-funding-open/18-inspect-shutdown-tx.bru): checks the shutdown refund output returned to node2 and derives the shutdown fee.

-- `07` opens the external-funded channel.
-- `08` signs the unsigned funding tx via `sign_external_funding_tx`.
