/** * END-TO-END TERMINAL PROTOCOL FIX VALIDATION * * This test validates that the complete terminal input flow works after the critical * protocol mismatch fix. It tests the complete user interaction flow: * type → enter → execute → unlock * * VALIDATION COVERAGE: * 1. Terminal input handler correctly formats messages with 'command' field * 2. Server accepts and processes terminal_input messages * 3. Commands execute successfully and return terminal output * 4. Bracket prompt format is properly detected * 5. Terminal unlocks after command completion */ import { JestTestUtilities } from './integration/terminal-history-framework/jest-test-utilities'; describe('E2E: Terminal Protocol Fix Validation', () => { const testUtils = JestTestUtilities.setupJestEnvironment('terminal-protocol-fix-e2e');
