Associate lnUrlResponse with the current LNURL.
When isValidLnUrl parses a new URL, it preserves the existing sendInfo.invoice. The conditions effect then skips checkLnUrlConditions because sendInfo.invoice && lnUrlResponse is true. lnUrlResponse remains from the previous URL, so handleContinue can use stale limits or transfer methods for the new URL.
Clear lnUrlResponse when sendInfo.lnUrl changes, or store its associated URL and compare it before skipping the fetch.

Review — fix lnurl send
Scope: 1-line change to the "check lnurl conditions" useEffect guard in src/screens/Wallet/Send/Form.tsx:511. Not protocol-critical (no VTXO, signing, forfeit, round, or exit logic touched).
What the bug was
sendInfo lives in FlowContext and survives navigation. lnUrlResponse is local component state and resets to undefined on unmount/remount (e.g. user hits Continue → navigates to SendDetails → presses Back).
On remount:
sendInfo.lnUrl✓ (still set from FlowContext)sendInfo.invoice✓ (set byhandleContinue→fetchInvoicebefore navigating away)lnUrlResponse→undefined(just reset)
Old guard (Form.tsx:511 before this PR):
if (sendInfo.lnUrl && sendInfo.invoice) returnBoth are truthy → effect bails early → lnUrlResponse stays undefined. The limits useEffect (lines 492-505) and buttonDisabled (lines 889-891) both gate on lnUrlResponse, so min/max enforcement and the amount read-only state silently break on the re-entered form.
New guard:
if (sendInfo.invoice && lnUrlResponse) returnOn remount lnUrlResponse is undefined → guard is false → checkLnUrlConditions runs → lnUrlResponse is repopulated. On first visit sendInfo.invoice is also undefined so the guard is false there too — no change to the happy path.
No infinite-loop risk: lnUrlResponse is absent from the effect's dependency array ([sendInfo.arkAddress, sendInfo.lnUrl]), so the .then(() => setLnUrlResponse(...)) callback does not re-trigger the effect.
The redundant sendInfo.lnUrl && prefix in the old guard is correctly dropped — line 509 already gates on !sendInfo.lnUrl.
The fix is correct.
One gap worth addressing
src/test/e2e/lnurl.test.ts — all three LNURL tests are test.skip, and src/test/screens/wallet/send-form.test.ts only covers isPlainOnchainTypedRecipient. The re-mount scenario (lnUrl + invoice pre-set in FlowContext, component mounts fresh) has no unit or e2e regression test. Given that this bug was invisible in CI and is easy to regress, a test along the lines of:
render SendForm with sendInfo.lnUrl and sendInfo.invoice already populated; assert
checkLnUrlConditionsis called andlnUrlResponseis populated
would be a worthwhile follow-up.
No security findings. No cross-repo API surface changed.
Brings the lnurl branch onto SDK 0.5 (sdk 0.5.0-rc.9, swap 0.1.0-rc.12). Rule: ts-sdk-0.5 wins for everything not lnurl; the branch's lnurl additions are kept. Conflicts and resolutions: - package.json: ts-sdk-0.5's dependency versions; kept only the branch's @arkade-os/lnurl-client entry (pnpm-lock.yaml auto-merged to the same shape). - src/screens/Wallet/Receive/QrCode.tsx: ts-sdk-0.5's file wholesale. The lnurl receive UI is dropped here and rebuilt as a separate rail module in a later commit; the swap-rail receive is intact. - src/providers/lnReceive.tsx, src/test/providers/lnReceive.test.tsx (deleted on ts-sdk-0.5, modified here): deleted. ts-sdk-0.5 folded the provider into providers/swaps.tsx; the branch's edits only removed the RFQ receive-admission path, not lnurl code. - src/test/screens/wallet/receive-lightning-error.test.tsx (deleted here, modified on ts-sdk-0.5): kept ts-sdk-0.5's version; it covers the swap-rail receive this merge restores. - src/providers/wallet.tsx: ts-sdk-0.5's swapRecordResolver block (and its removal of the storage migration); kept the lnurlResolver / syncLnurlActivity imports and activity.use(lnurlResolver()). - src/screens/Wallet/Send/Form.tsx: the lnurl-client resolve() call with #999's early-return guard (invoice && lnUrlResponse). - src/lib/lnurl.ts: the branch's slimmed module, plus checkLnUrlInvoice carrying #1003's invoice decode + amount-match check, which requestInvoice does not do; Form.tsx calls it on the bolt11. - src/test/lib/lnurl.test.ts: the branch's client-based tests, with #1003's invalid-invoice and amount-mismatch cases re-pointed at checkLnUrlInvoice.
