…it#612) - generateIdempotencyKey: deterministic SHA-256 hex key from invoiceId, payer, amount - isKnownKey / registerKey / clearKeys: in-memory Set-backed registry - Exported from index.ts alongside existing Deduplicator - Unit tests: determinism, input sensitivity, nonce variation, registry lifecycle Closes Stellar-split#612
…#614) - searchByMemo(invoices, query, opts?) filters invoices by memo substring - case-insensitive by default; opts.caseSensitive=true for exact case - empty query returns all invoices unchanged - invoices with undefined/null memo are skipped without error - 6 unit tests covering all acceptance criteria Closes Stellar-split#614
…r class (Stellar-split#617) - verifyWebhookSignature(payload, signature, secret): boolean — HMAC-SHA256 with timing-safe comparison - verifyWebhookSignatureOrThrow: wrapper that throws WebhookVerificationError - WebhookVerificationError: typed error for consumers who prefer throwing - Exported from src/index.ts alongside existing webhookMiddleware exports - 7 unit tests covering valid/invalid signatures, tampered payloads, malformed input, and error class Closes Stellar-split#617
…nders (Stellar-split#616) - scheduleReminder(invoiceId, offsetMs) returns opaque reminderId - cancelReminder(reminderId): boolean — true if pending and cancelled, false otherwise - getPendingReminders(): array of { reminderId, invoiceId, remindAt } - clearAllReminders(): void — clears all timers and persisted state (test teardown) - Cancelled reminders never fire even if their scheduled time passes - 6 unit tests using fake timers Closes Stellar-split#616
…plit#618) - paginateArray<T>(items, { page, pageSize }) returns { data, total, totalPages, hasNext, hasPrev } - page is 1-indexed; out-of-range pages return data: [] - pageSize must be 1–200, otherwise throws SdkError with INVALID_RECIPIENT code - Exported from src/index.ts alongside existing horizon utilities - 7 unit tests covering first/last pages, out-of-range, boundary pageSize, empty arrays, and error code Closes Stellar-split#618
…ar-split#619) - compressMetadata(obj, maxBytes=512): JSON + base64url encode with size validation - decompressMetadata(encoded): base64url decode + JSON parse - Both throw SdkError with CONTRACT_REJECTED code on invalid input or size violation - Exported from src/index.ts - 6 unit tests: round-trip, nested objects, base64url format, size limit, invalid input Closes Stellar-split#619

Closes #619
What
Adds JSON + base64url round-trip helpers for compact invoice metadata storage (e.g. memos, IPFS payloads).
