{"content":"Development journal: Native IDChat migration Task 1 completed in IDChat-APP. Added the native chat Jest harness behind test:chat-native, configured jest-expo with node-compatible setup, added Buffer/atob/btoa polyfills, and created the first src/chat-native harness test. Installed the plan-required Expo-compatible native chat dependencies expo-sqlite and expo-file-system, Socket.IO client 4.7.5, and Jest 29 tooling with matching @types/jest 29.x. Local plan adjustment: Jest ignores the local .claude directory and transforms expo-modules-core so the Expo 53 test runner works in this repo. Verification: yarn test:chat-native src/chat-native/__tests__/testHarness.test.ts passed with 1 test suite and 1 test passing. Commit: ca5bb01 chore: add native chat test harness.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
