# Research Task: Directory Path Extraction and State Management ## Research Assignment **Task**: Analyze the directory path extraction logic and session state management **Focus Areas**: 1. **Directory path validation** - Examine `_validateAndCleanDirectoryPath` method 2. **Session state updates** - Analyze how `currentWorkingDirectory` is updated in session 3. **Output parsing logic** - Review how pwd output is extracted from shell output 4. **State persistence** - Investigate if the working directory state persists correctly 5. **Terminal ANSI sequence handling** - Check if ANSI escape sequences interfere with parsing **Key Files to Analyze**: - `/Users/duynguyen/www/devpocket-mvp-app/lib/core/services/ssh_service.dart` (focus on directory path extraction logic) - `/Users/duynguyen/www/devpocket-mvp-app/lib/data/models/ssh_session.dart` (session state management) **Log Evidence Analysis**: - Line 70 shows: `pwd\n\^[[?2004l/home\n\^[[?2004h\^[]0;testpwd@vmi2757774: /home\^G` - The `/home` path is embedded in ANSI escape sequences - The output contains shell prompt formatting that may interfere with parsing **Research Questions**: 1. Is the directory path `/home` being correctly extracted from the ANSI-formatted output? 2. Are the ANSI escape sequences (`\^[[?2004l`, `\^[[?2004h`) being properly handled? 3. Is the session state update (`copyWith(currentWorkingDirectory:)`) working correctly? 4. Why does the UI still show `~` as working directory instead of `/home`? **Expected Output**: Detailed analysis report in `./plans/reports/002-from-researcher-path-extraction-to-planner-report.md` **Success Criteria**: - Analyze the pwd output parsing logic for ANSI sequence handling - Verify session state update mechanism is working - Identify why extracted directory path isn't being reflected in UI - Propose improvements to path extraction robustness
