Code Review
This pull request introduces the ability to include a Lightning Address (lud16) in Nostr Wallet Connect (NWC) connection URLs and expands support for several NIP-47 methods, including get_info, get_balance, make_invoice, lookup_invoice, list_transactions, and sign_message. Key changes include updates to the NWC connection model, the addition of a URL builder utility with associated tests, and UI enhancements to toggle the inclusion of the Lightning Address. Feedback focuses on improving error handling and permission enforcement within NostrWalletConnectStore.ts. Specifically, it is noted that throwing errors during event validation may lead to silent failures, and several newly added methods lack consistent permission checks or use misleading error messages when access is restricted.

This pull request introduces the ability to include a Lightning Address (lud16) in Nostr Wallet Connect (NWC) connection URLs. Key changes include adding a UI toggle in the connection settings, updating the NWC connection models and stores to persist this preference, and implementing a utility for constructing the connection string. Furthermore, the NWC request handling logic was refactored to improve permission validation across multiple methods and standardize error reporting with a new RESTRICTED error code. Unit tests for the URL construction utility were also included. I have no feedback to provide as there were no review comments to evaluate.

Code Review
This pull request implements support for including Lightning Addresses (lud16) in Nostr Wallet Connect (NWC) connection URLs. It updates the NWC connection model, introduces a dedicated URL builder utility with unit tests, and refactors the NostrWalletConnectStore to handle new NWC methods and permission checks. The UI now features a toggle for users to include their Lightning Address when creating connections. Review feedback suggests returning a failure status when a connection URL cannot be regenerated due to missing keys, ensuring the pay_invoice handler supports zero-amount invoices as per NIP-47, and refactoring duplicated logic used to check for active lightning addresses.

This pull request implements support for including Lightning Addresses (lud16) in Nostr Wallet Connect (NWC) connection URLs and expands the supported NWC methods to include get_info, get_balance, and make_invoice, among others. The changes include updates to the NWC connection model, a new URL builder utility, and UI enhancements for managing connection settings. Feedback identifies a potential precision loss when converting millisatoshis to satoshis for zero-amount invoices and recommends exposing the Lightning Address toggle in the edit view to improve user flexibility.

Code Review
This pull request enhances the Nostr Wallet Connect (NWC) implementation by adding NIP-44 encryption support, LUD-16 lightning address integration, and improved budget enforcement. Significant changes include refactoring the CLN backend for better fee and amount handling, implementing activity history limits to prevent memory growth, and ensuring NIP-47 specification compliance for method permissions and error codes. Review feedback identified critical type mismatches in the NIP-44 encryption logic where hex strings were passed instead of the required byte arrays for conversation key generation, which would result in runtime errors.
Ensures toNip47ErrorCode() can properly map error types that were already being thrown at runtime (line 3655) but missing from the enum definition. This fixes NWC clients receiving raw Error strings instead of proper NIP-47 error responses. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

The normalizeNWCConnectionData function had a logic error where: 1. Line 89 set includeLightningAddress to false using ?? operator 2. Line 95 then checked if it was === undefined (never true) 3. Result: auto-migration from lud16 metadata never occurred Fix: - Check includeLightningAddress from source BEFORE spreading - Apply defaults and fallback logic in correct order - Ensures lud16 values in metadata properly enable includeLightningAddress All 25 NWCConnection tests now pass: ✅ Auto-migration tests fixed (were failing) ✅ Budget tracking tests pass ✅ Activity rotation tests pass ✅ Race condition handling tests pass Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
GPT-5.4 code review identified blocker: msat→sat conversion was using Math.ceil which OVERCHARGES users on non-whole-sat amounts. Spec & tests require Math.floor: - 1500 msat should become 1 sat (not 2 sat) - 1001 msat should become 1 sat (not 2 sat) - Fee limit is hard ceiling (must not exceed) ✅ uses floor - Payment amount must not overcharge (must not exceed) ✅ now uses floor Changes: - pay_invoice: Math.ceil → Math.floor - getInvoiceAmount: Math.ceil → Math.floor - Updated comments from 'rounded UP' to 'truncated DOWN' - Updated warning logs to show truncation, not overpayment All 11 SubSatoshiRounding tests pass ✅ All 25 NWCConnection tests pass ✅ This is a critical user-facing fix preventing unauthorized overcharges.

CRITICAL Issues Fixed: 1. Sub-satoshi budget bypass (GPT-5.4 finding) - Sub-satoshi amounts (1-999 msat) were flooring to 0 sats and bypassing budget checks - Now charge at least 1 sat to budget for any positive msat request - Budget enforcement: min(amountSats, 1) when flooring reduces to 0 - Locations: stores/NostrWalletConnectStore.ts:2149-2158, 2743-2745 2. LUD-16 validation allows invalid formats (GPT-5.4 finding) - Was accepting consecutive dots (e.g., user..name@domain) - Now rejects: consecutive dots, leading dots, trailing dots - Validation tightened with explicit checks - Location: utils/NostrWalletConnectUrlUtils.ts:15-29 Changes: - calculatebudgetChargeAmountSats in handleLightningPayInvoice to ensure budget enforcement - Tightened LUD-16 regex to prevent malformed local parts - Added validation checks for dot positions - Updated finalizePayment to accept budgetChargeAmountSats parameter - Added 3 new LUD-16 edge case tests (consecutive dots, leading/trailing dots) Tests: - 810/810 passing (3 new tests) - LUD-16 validation: 18 test cases - Sub-satoshi rounding: 7 test cases - TypeScript: clean This addresses critical findings from multi-review synthesis (GPT-5.4 was correct about the budget bypass vulnerability).
