+### Prompt Metadata
+Agent: pc_agent
+Task: OTA and configuration CLI/GUI updates
+Target File(s): pc/cli/ddsctl.py, pc/gui/MainWindow.go, tests/cli/test_ddsctl.py, tests/gui/*
+Related Docs: docs/design/pc_ui_mockups.md
+
+### Prompt Body
+Review and implement OTA and configuration support for the ESP8266-01.
+- Add `ota_upload`, `show_config`, and `edit_config` commands to the CLI.
+- Extend the Qt GUI (`MainWindow.go`) with buttons for OTA upload and viewing the current configuration.
+- Ensure the CLI and GUI read the unified `config/pins.conf` file.
+- Use stubs or fallbacks so tests pass without hardware.
+- Update unit tests for the new commands.
+- Document progress in `docs/progress/` and update `TODO.md` accordingly.
