{"content":"Development diary: Task 2 Shared Wallet Spend Queue.\n\nTDD RED: added tests/wallet/spendQueue.test.mjs first, then ran npm run build && node --test tests/wallet/spendQueue.test.mjs. Build passed and the test failed as expected because dist/core/wallet/spendQueue.js did not exist.\n\nImplementation: extracted the existing local mnemonic signer wallet spend queue into src/core/wallet/spendQueue.ts with the same serialization, failure-release, and queue-key behavior. Updated src/core/signing/localMnemonicSigner.ts to import withWalletSpendQueue and resolveWalletSpendQueueKey instead of keeping private helpers.\n\nVerification: npm run build && node --test tests/wallet/spendQueue.test.mjs tests/chain/localMnemonicSigner.test.mjs tests/wallet/nativeWallet.test.mjs passed. git diff --check passed.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
