update the install packages to copy the python site packages to venv

Documents the new layers introduced over the past several commits.

- docs/19_frame_io_and_alm_helpers.md (new): full reference for the
  FrameIO and AlmTester helpers — three access levels (high/mid/low),
  full API tables, fixture wiring, cookbook patterns, and §7
  describing the four-phase SETUP/PROCEDURE/ASSERT/TEARDOWN test
  pattern with the three template flavors plus a §7.4 link to the
  PSU+LIN template.

- docs/14_power_supply.md: rewritten and expanded.
    §3 cross-platform port resolution (Windows / WSL1 / WSL2 +
       usbipd-win / Linux native compatibility table)
    §4 auto-detection via idn_substr
    §5 session-managed power: contract for tests, must-not list,
       what changed in the existing tests
    §6 the settle-then-validate pattern: two-delays table (PSU
       bench-dependent vs ECU firmware-dependent), copy-paste
       example, tuning guidance for ECU_VALIDATION_TIME_S
    §6 PSU settling characterization (-m psu_settling)
    §7 library API reference table + safe_off_on_close
    §9 troubleshooting expanded with WSL2 usbipd-win + dialout

- docs/18_test_catalog.md: voltage-tolerance section refreshed for
  the settle-then-validate shape, new "Hardware – PSU settling
  (opt-in)" category, new §8 "Hardware-test infrastructure"
  documenting conftest.py, frame_io.py, alm_helpers.py,
  psu_helpers.py, and both templates.

- docs/05_architecture_overview.md: components list split into
  framework core / hardware test layer / artifacts. Mermaid diagram
  gained a Hardware-test helpers subgraph showing FrameIO,
  AlmTester, rgb_to_pwm, and the templates. Data/control flow
  summary describes the session-managed PSU and the helper layer.

- docs/15_report_properties_cheatsheet.md: PSU section split into
  per-test (function-scoped rp) and module-scoped (testsuite
  property) blocks; added psu_resolved_port, psu_resolved_idn,
  psu_settled_s, validation_time_s.

- docs/README.md: links to the new doc 19.

- README.md, TESTING_FRAMEWORK_GUIDE.md: project-structure trees
  expanded to show the full current layout — every file and
  directory under tests/hardware/ (conftest, helpers, templates,
  tests), tests/unit/, config/, docs/, scripts/, and vendor/.

+# ECU Tests Framework
+
+Python-based ECU testing framework built on pytest, with a pluggable LIN communication layer (Mock and MUM, with the deprecated BabyLIN adapter retained for backward compatibility), configuration via YAML, and enhanced HTML/XML reporting with rich test metadata.
+
+> **Heads-up:** the BabyLIN adapter is **deprecated**. New tests and deployments should target MUM. BabyLIN is documented below only so existing setups can keep running while they migrate.
+
+## Highlights
+
+- **MUM (Melexis Universal Master) adapter** — current default for hardware tests; networked LIN master with built-in power control
+- Mock LIN adapter for fast, hardware-free development
+- BabyLIN adapter (DEPRECATED) using the vendor SDK's Python wrapper
+- Hex flashing scaffold you can wire to UDS
+- Rich pytest fixtures and example tests
+- Self-contained HTML report with Title, Requirements, Steps, and Expected Results extracted from test docstrings
+- JUnit XML report for CI/CD
+
+## Quick links
+
+- Using the framework (common runs, markers, CI, Pi): `docs/12_using_the_framework.md`
+- Plugin overview (reporting, hooks, artifacts): `docs/11_conftest_plugin_overview.md`
+- Power supply (Owon) usage and troubleshooting: `docs/14_power_supply.md`
+- Report properties cheatsheet (standard keys): `docs/15_report_properties_cheatsheet.md`
+- MUM source scripts (vendor reference): [vendor/automated_lin_test/README.md](vendor/automated_lin_test/README.md)
+
+## TL;DR quick start (copy/paste)
+
+Mock (no hardware):
+
+```powershell
+python -m venv .venv; .\.venv\Scripts\Activate.ps1; pip install -r requirements.txt; pytest -m "not hardware" -v
+```
+
+Hardware via MUM (current default):
+
+```powershell
+# 1. Install Melexis 'pylin' and 'pymumclient' (see vendor/automated_lin_test/install_packages.sh)
+# 2. Make sure the MUM is reachable (default IP 192.168.7.2)
+$env:ECU_TESTS_CONFIG = ".\config\mum.example.yaml"; pytest -m "hardware and mum" -v
+```
+
+Hardware via BabyLIN (DEPRECATED — kept for existing rigs only):
+
+```powershell
+# Place BabyLIN_library.py and native libs under .\vendor per vendor/README.md first
+$env:ECU_TESTS_CONFIG = ".\config\babylin.example.yaml"; pytest -m "hardware and babylin" -v
+```
+
+## Quick start (Windows PowerShell)
+
+1) Create a virtual environment and install dependencies
+
+```powershell
+python -m venv .venv
+.\.venv\Scripts\Activate.ps1
+pip install -r requirements.txt
+```
+
+2) Run the mock test suite (default interface)
+
+```powershell
+python.exe -m pytest -m "not hardware" -v
+```
+
+3) View the reports
+
+- HTML: `reports/report.html`
+- JUnit XML: `reports/junit.xml`
+
+Tip: You can change output via `--html` and `--junitxml` CLI options.
+
+## Quick start (WSL on Windows)
+
+Use this approach when running from **Windows Subsystem for Linux** instead of PowerShell.
+
+### 1. Open a WSL terminal and navigate to the project
+
+Clone or access the repo from within WSL. If the project lives on the Windows filesystem (e.g. `C:\Users\you\ecu-tests`), it is available at:
+
+```bash
+cd /mnt/c/Users/<your-username>/ecu-tests
+```
+
+### 2. Create a virtual environment and install dependencies
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### 3. Run the mock test suite (no hardware needed)
+
+```bash
+python -m pytest -m "not hardware" -v
+```
+
+### 4. Install Melexis packages into the venv (required for hardware tests)
+
+`pylin`, `pymumclient`, and `pylinframe` are not on PyPI — they ship with the Melexis IDE.  
+On Windows they live at:
+
+```
+C:\Program Files\Melexis\Melexis IDE\plugins\com.melexis.mlxide.python_1.2.0.202408130945\python\Lib\site-packages
+```
+
+which WSL exposes at `/mnt/c/Program Files/Melexis/Melexis IDE/...`.
+
+**With your venv already activated**, copy the packages directly into it:
+
+```bash
+source .venv/bin/activate   # skip if already active
+
+MELEXIS_SITE="/mnt/c/Program Files/Melexis/Melexis IDE/plugins/com.melexis.mlxide.python_1.2.0.202408130945/python/Lib/site-packages"
+VENV_SITE=$(python -c "import site; print(site.getsitepackages()[0])")
+
+cp -r "$MELEXIS_SITE/pylin"       "$VENV_SITE/"
+cp -r "$MELEXIS_SITE/pymumclient" "$VENV_SITE/"
+cp -r "$MELEXIS_SITE/pylinframe"  "$VENV_SITE/"
+```
+
+Verify the installation:
+
+```bash
+python -c "import pylin; import pymumclient; print('OK')"
+```
+
+> **Alternative:** You can also run `bash vendor/automated_lin_test/install_packages.sh` after updating the `MELEXIS_SITE_PACKAGES` path in that script — but the commands above are simpler and target the venv directly.
+
+### 5. Run hardware tests via MUM
+
+```bash
+export ECU_TESTS_CONFIG=./config/mum.example.yaml
+python -m pytest -m "hardware and mum" -v
+```
+
+### 6. Run hardware tests via BabyLIN (DEPRECATED)
+
+> **Deprecated.** The BabyLIN adapter is kept for backward compatibility only; new work should target MUM (step 5). The BabyLIN SDK also ships Windows-only native libraries (`.dll`), so these tests cannot run under WSL unless you have a Linux-compatible `.so` build of the SDK.
+
+```bash
+export ECU_TESTS_CONFIG=./config/babylin.example.yaml
+python -m pytest -m "hardware and babylin" -v
+```
+
+### 7. View reports
+
+Open the HTML report directly in Windows from the WSL terminal:
+
+```bash
+explorer.exe reports/report.html
+```
+
+Or from PowerShell/CMD:
+
+```powershell
+start .\reports\report.html
+```
+
+---
+
+## Reporting: Metadata in HTML
+
+We extract these fields from each test’s docstring and render them in the HTML report:
+
+- Title
+- Description
+- Requirements (e.g., REQ-001)
+- Test Steps
+- Expected Result
+
+Markers like `smoke`, `hardware`, and `req_00x` are also displayed.
+
+Example docstring format used by the plugin:
+
+```python
+"""
+Title: Mock LIN Interface - Send/Receive Echo Test
+
+Description: Validates basic send/receive functionality using the mock LIN interface with echo behavior.
+
+Requirements: REQ-001, REQ-003
+
+Test Steps:
+1. Connect to mock interface
+2. Send frame ID 0x01 with data [0x55]
+3. Receive the echo within 100ms
+4. Assert ID and data integrity
+
+Expected Result:
+- Echoed frame matches sent frame
+"""
+```
+
+## Configuration
+
+Default config is `config/test_config.yaml`. Override via the `ECU_TESTS_CONFIG` environment variable.
+
+```powershell
+$env:ECU_TESTS_CONFIG = (Resolve-Path .\config\test_config.yaml)
+```
+
+### MUM configuration (default for hardware)
+
+Template: `config/mum.example.yaml`
+
+```yaml
+interface:
+  type: mum
+  host: 192.168.7.2          # MUM IP (USB-RNDIS default)
+  lin_device: lin0           # MUM LIN device name
+  power_device: power_out0   # MUM power-control device (built-in PSU)
+  bitrate: 19200             # LIN baudrate
+  boot_settle_seconds: 0.5   # Wait after power-up before sending the first frame
+  frame_lengths:
+    0x0A: 8                  # ALM_Req_A
+    0x11: 4                  # ALM_Status
+```
+
+The MUM has its own power output, so `power_supply.enabled: false` is the
+typical setting when using MUM. The Owon PSU support remains for over/under-
+voltage scenarios but is independent of the LIN interface.
+
+### BabyLIN configuration (DEPRECATED)
+
+> Retained for backward compatibility. Prefer the MUM configuration above.
+
+Template: `config/babylin.example.yaml`
+
+```yaml
+interface:
+  type: babylin          # deprecated; prefer "mum" or "mock"
+  channel: 0             # Channel index used by the SDK wrapper
+  bitrate: 19200         # Usually determined by SDF
+  sdf_path: ./vendor/Example.sdf
+  schedule_nr: 0         # Start this schedule on connect (-1 to skip)
+```
+
+### LIN adapter capabilities
+
+| Adapter | Power control | Diagnostic frames (Classic checksum) | Passive listen |
+| --- | --- | --- | --- |
+| `mock` | n/a | n/a | yes (queue-based) |
+| `mum` | yes (`power_out0`) | yes (`MumLinInterface.send_raw()` → `ld_put_raw`) | no — `receive(id)` triggers a slave read |
+| `babylin` (deprecated) | external (Owon PSU) | via SDF / `BLC_sendCommand` | yes (frame queue) |
+
+Switch to hardware profile and run only hardware tests (MUM example):
+
+```powershell
+$env:ECU_TESTS_CONFIG = (Resolve-Path .\config\mum.example.yaml)
+python.exe -m pytest -m hardware -v
+```

+
+## Usage recipes
+
+- Run everything (mock and any non-hardware tests):
+
+```powershell
+python.exe -m pytest -v
+```
+
+- Run by marker:
+
+```powershell
+python.exe -m pytest -m "smoke" -v
+python.exe -m pytest -m "req_001" -v
+```
+
+- Run in parallel:
+
+```powershell
+python.exe -m pytest -n auto -v
+```
+
+- Run the plugin self-test (verifies reporting artifacts under `reports/`):
+
+```powershell
+python -m pytest tests\plugin\test_conftest_plugin_artifacts.py -q
+```
+
+- Generate separate HTML/JUnit reports for unit vs non-unit tests:
+
+```powershell
+./scripts/run_two_reports.ps1
+```
+
+## BabyLIN adapter notes (DEPRECATED)
+
+> Kept for backward compatibility. New work should target the MUM adapter.
+
+The `ecu_framework/lin/babylin.py` implementation uses the official `BabyLIN_library.py` wrapper from the SDK. Put `BabyLIN_library.py` under `vendor/` (or on `PYTHONPATH`) along with the SDK's platform-specific libraries. Configure `sdf_path` and `schedule_nr` to load an SDF and start a schedule during connect. The adapter sends frames via `BLC_mon_set_xmit` and receives via `BLC_getNextFrameTimeout`. Instantiating `BabyLinInterface` emits a `DeprecationWarning`.
+
+## Docs and references
+
+- Guide: `TESTING_FRAMEWORK_GUIDE.md` (deep dive with examples and step-by-step flows)
+- Reports: `reports/report.html` and `reports/junit.xml` (generated on each run)
+- CI summary: `reports/summary.md` (machine-friendly run summary)
+- Requirements coverage: `reports/requirements_coverage.json` (requirement → tests mapping)
+  - Tip: Open the HTML report on Windows with: `start .\reports\report.html`
+- Configs: `config/test_config.yaml`, `config/mum.example.yaml`, `config/babylin.example.yaml` (deprecated) — copy and modify for your environment
+- BabyLIN SDK placement and notes: `vendor/README.md` (deprecated; only relevant for legacy BabyLIN rigs)
+- Docs index: `docs/README.md` (run sequence, config resolution, reporting, call flows)
+ - Raspberry Pi deployment: `docs/09_raspberry_pi_deployment.md`
+ - Build custom Pi image: `docs/10_build_custom_image.md`
+ - Pi scripts: `scripts/pi_install.sh`, `scripts/ecu-tests.service`, `scripts/ecu-tests.timer`, `scripts/run_tests.sh`
+
+## Troubleshooting
+
+- HTML report missing columns: ensure `pytest.ini` includes `-p conftest_plugin` in `addopts`.
+- ImportError for BabyLIN_library (DEPRECATED path): verify `vendor/BabyLIN_library.py` placement and that required native libraries (DLL/.so) from the SDK are available on PATH/LD_LIBRARY_PATH. Consider migrating to the MUM adapter, which avoids vendor DLLs entirely.
+- Permission errors in PowerShell: run the venv's full Python path or adjust ExecutionPolicy for scripts.
+- Import errors: activate the venv and reinstall `requirements.txt`.
+
+## Owon Power Supply (SCPI) — library, config, tests, and quick demo
+
+We provide a reusable pyserial-based library, a hardware test integrated with the central config,
+and a minimal quick demo script.
+
+- Library: `ecu_framework/power/owon_psu.py` (class `OwonPSU`, `SerialParams`, `scan_ports`)
+- Central config: `config/test_config.yaml` (`power_supply` section)
+  - Optionally merge `config/owon_psu.yaml` or set `OWON_PSU_CONFIG` to a YAML path
+- Hardware test: `tests/hardware/test_owon_psu.py` (skips unless `power_supply.enabled` is true)
+- quick demo: `vendor/Owon/owon_psu_quick_demo.py` (reads `OWON_PSU_CONFIG` or `config/owon_psu.yaml`)
+
+Quick setup (Windows PowerShell):
+
+```powershell
+# Ensure dependencies
+pip install -r .\requirements.txt
+
+# Option A: configure centrally in test_config.yaml
+#   Edit config\test_config.yaml and set:
+#   power_supply.enabled: true
+#   power_supply.port: COM4
+
+# Option B: use a separate machine-specific YAML
+copy .\config\owon_psu.example.yaml .\config\owon_psu.yaml
+# edit COM port and options in .\config\owon_psu.yaml
+
+# Run the hardware PSU test (skips if disabled or missing port)
+pytest -k test_owon_psu_idn_and_optional_set -m hardware -q
+
+# Run the quick demo script
+python .\vendor\Owon\owon_psu_quick_demo.py
+```
+
+YAML keys supported by `power_supply`:
+
+```yaml
+power_supply:
+  enabled: true
+  port: COM4           # or /dev/ttyUSB0
+  baudrate: 115200
+  timeout: 1.0
+  eol: "\n"          # or "\r\n"
+  parity: N            # N|E|O
+  stopbits: 1          # 1|2
+  xonxoff: false
+  rtscts: false
+  dsrdtr: false
+  idn_substr: OWON
+  do_set: false
+  set_voltage: 5.0
+  set_current: 0.1
+```
+
+Troubleshooting:
+- If `*IDN?` is empty, confirm port, parity/stopbits, and `eol` (try `\r\n`).
+- On Windows, if COM>9, use `\\.\COM10` style in some tools; here plain `COM10` usually works.
+- Ensure only one program opens the COM port at a time.
+
+## Next steps
+
+- Replace `HexFlasher` with a production flashing routine (UDS)
+- Expand tests for end-to-end ECU workflows and requirement coverage

+# ECU Testing Framework - Complete Guide
+
+> **Heads-up:** the BabyLIN LIN adapter is **deprecated** and retained for backward compatibility only. New tests and deployments should target the MUM (Melexis Universal Master) adapter — see `docs/16_mum_internals.md`. The BabyLIN-related sections below are kept so existing rigs can still be maintained.
+
+## Overview
+
+This comprehensive ECU Testing Framework provides a robust solution for testing Electronic Control Units (ECUs) using pytest with the MUM LIN adapter (current) or the deprecated BabyLIN adapter. The framework includes detailed test documentation, enhanced reporting, mock interfaces for development, and real hardware integration capabilities.
+
+## Framework Features
+
+### ✅ **Complete Implementation Status**
+- **✅ pytest-based testing framework** with custom plugins
+- **✅ MUM (Melexis Universal Master) LIN integration** via the `pylin` / `pymumclient` packages — current default
+- **⚠️ BabyLIN LIN integration (DEPRECATED)** via the official SDK Python wrapper (`BabyLIN_library.py`)
+- **✅ Mock interface for hardware-independent development**
+- **✅ Enhanced HTML/XML reporting with test metadata**
+- **✅ Detailed test documentation extraction**
+- **✅ Configuration management with YAML**
+- **✅ Hex file flashing capabilities (scaffold)**
+- **✅ Custom pytest markers for requirement traceability**
+
+## Enhanced Reporting System
+
+### Test Metadata Integration
+
+The framework automatically extracts detailed test information from docstrings and integrates it into reports:
+
+**HTML Report Features:**
+- **Title Column**: Clear test descriptions extracted from docstrings
+- **Requirements Column**: Requirement traceability (REQ-001, REQ-002, etc.)
+- **Enhanced Test Details**: Description, test steps, and expected results
+- **Marker Integration**: Custom pytest markers for categorization
+
+**Example Test Documentation Format:**
+```python
+@pytest.mark.smoke
+@pytest.mark.req_001
+def test_mock_send_receive_echo(self, mock_interface):
+    """
+    Title: Mock LIN Interface - Send/Receive Echo Test
+    
+    Description: Validates basic send/receive functionality using the mock
+    LIN interface with echo behavior for development testing.
+    
+    Requirements: REQ-001, REQ-003
+    
+    Test Steps:
+    1. Connect to mock LIN interface
+    2. Send a test frame with ID 0x01 and data [0x55]
+    3. Receive the echoed frame within 100ms timeout
+    4. Verify frame ID and data integrity
+    
+    Expected Result:
+    - Frame should be echoed back successfully
+    - Received data should match sent data exactly
+    - Operation should complete within timeout period
+    """
+```
+
+### Report Generation
+
+**HTML Report (`reports/report.html`):**
+- Interactive table with sortable columns
+- Test titles and requirements clearly visible
+- Execution duration and status tracking
+- Enhanced metadata from docstrings
+
+**XML Report (`reports/junit.xml`):**
+- Standard JUnit XML format for CI/CD integration
+- Test execution data and timing information
+- Compatible with most CI systems (Jenkins, GitLab CI, etc.)
+
+## Project Structure
+
+The hardware-test layer is split across three modules — see
+[`docs/19_frame_io_and_alm_helpers.md`](docs/19_frame_io_and_alm_helpers.md)
+for the API and the four-phase test pattern, and
+[`docs/14_power_supply.md`](docs/14_power_supply.md) §5 for the
+session-managed PSU lifecycle.

+
+## Running Tests
+
+### Basic Test Execution
+
+```powershell
+# Run all tests with verbose output
+python -m pytest -v
+
+# Run specific test suite
+python -m pytest tests\test_smoke_mock.py -v
+
+# Run tests with specific markers
+python -m pytest -m "smoke" -v
+python -m pytest -m "req_001" -v
+
+# Run hardware tests (requires deprecated BabyLIN hardware); join with adapter marker
+# Prefer MUM for new work: pytest -m "hardware and mum" -v
+python -m pytest -m "hardware and babylin" -v
+```
+
+### Unit Tests (fast, no hardware)
+
+Run only unit tests using the dedicated marker or by path:
+
+```powershell
+# By marker
+python -m pytest -m unit -q
+
+# By path
+python -m pytest tests\unit -q
+
+# Plugin self-tests (verifies reporting artifacts)
+python -m pytest tests\plugin -q
+```
+
+Reports still go to `reports/` (HTML and JUnit per defaults). Open the HTML on Windows with:
+
+```powershell
+start .\reports\report.html
+```
+
+Coverage: enabled by default via pytest.ini. To disable locally:
+
+```powershell
+python -m pytest -q -o addopts=""
+```
+
+Optional HTML coverage:
+
+```powershell
+python -m pytest --cov=ecu_framework --cov-report=html -q
+start .\htmlcov\index.html
+```
+
+See also: `docs/13_unit_testing_guide.md` for more details and examples.
+
+### Report Generation
+
+Tests automatically generate enhanced reports:
+- **HTML Report**: `reports/report.html` - Interactive report with metadata
+- **XML Report**: `reports/junit.xml` - CI/CD compatible format
+
+## Configuration
+
+### Test Configuration (`config/test_config.yaml`)
+
+```yaml
+interface:
+  type: mock  # or "mum" for hardware (current); "babylin" is deprecated
+  timeout: 1.0
+
+flash:
+  hex_file_path: firmware/ecu_firmware.hex
+  flash_timeout: 30.0
+
+ecu:
+  name: Test ECU
+  lin_id_range: [0x01, 0x3F]
+```
+
+### BabyLIN Configuration (`config/babylin.example.yaml`) — DEPRECATED
+
+> Retained for backward compatibility. Prefer `config/mum.example.yaml` for new work.
+
+```yaml
+interface:
+  type: babylin           # deprecated; prefer "mum"
+  channel: 0              # channel index used by the SDK wrapper
+  bitrate: 19200          # typically set by SDF
+  sdf_path: ./vendor/Example.sdf
+  schedule_nr: 0          # schedule to start on connect
+```
+
+## Test Categories
+
+### 1. Mock Interface Tests (`test_smoke_mock.py`)
+
+**Purpose**: Hardware-independent development and validation
+- ✅ Send/receive echo functionality
+- ✅ Master request/response testing
+- ✅ Timeout behavior validation  
+- ✅ Frame validation boundary testing
+- ✅ Parameterized boundary tests for comprehensive coverage
+
+**Status**: **7 tests passing** - Complete implementation
+
+### 2. Hardware Smoke Tests (`test_babylin_hardware_smoke.py`) — DEPRECATED
+
+**Purpose**: Basic BabyLIN hardware connectivity validation (deprecated path; prefer the MUM smoke tests under `tests/hardware/`)
+- ✅ SDK wrapper import and device open
+- ✅ Interface connection establishment
+- ✅ Basic send/receive operations
+- ✅ Error handling and cleanup
+
+**Status**: Ready for hardware testing
+
+### 3. Hardware Integration Tests (`test_hardware_placeholder.py`)
+
+**Purpose**: Full ECU testing workflow with real hardware
+- ECU flashing with hex files
+- Communication protocol validation
+- Diagnostic command testing
+- Performance and stress testing
+
+**Status**: Framework ready, awaiting ECU specifications
+
+## Custom Pytest Markers
+
+The framework includes custom markers for test categorization and requirement traceability:
+
+```python
+# In pytest.ini
+markers =
+    smoke: Basic functionality tests
+    integration: Integration tests requiring hardware
+    hardware: Tests requiring physical hardware (MUM or, deprecated, BabyLin)
+  babylin: DEPRECATED. Tests targeting the legacy BabyLIN SDK adapter
+  mum: Tests targeting the current MUM (Melexis Universal Master) adapter
+  unit: Fast unit tests (no hardware)
+    boundary: Boundary condition and edge case tests
+    req_001: Tests validating requirement REQ-001 (LIN Interface Basic Operations)
+    req_002: Tests validating requirement REQ-002 (Master Request/Response)
+    req_003: Tests validating requirement REQ-003 (Frame Validation)
+    req_004: Tests validating requirement REQ-004 (Timeout Handling)
+```
+
+## BabyLIN Integration Details (DEPRECATED)
+
+> Kept for backward compatibility only. New tests should use the MUM adapter (`docs/16_mum_internals.md`).
+
+### SDK Python wrapper
+
+The deprecated BabyLIN adapter uses the official SDK Python wrapper `BabyLIN_library.py` (placed under `vendor/`) and calls its BLC_* APIs.
+
+Key calls in the adapter (`ecu_framework/lin/babylin.py`):
+- `BLC_getBabyLinPorts`, `BLC_openPort` — discovery and open
+- `BLC_loadSDF`, `BLC_getChannelHandle`, `BLC_sendCommand('start schedule N;')` — SDF + scheduling
+- `BLC_mon_set_xmit` — transmit
+- `BLC_getNextFrameTimeout` — receive
+- `BLC_sendRawMasterRequest` — master request (length then bytes)
+
+## Development Workflow
+
+### 1. Development Phase
+```powershell
+# Use mock interface for development
+python -m pytest tests\test_smoke_mock.py -v
+```
+
+### 2. Hardware Integration Phase
+```powershell
+# Test with deprecated BabyLIN hardware (legacy rigs only)
+# Prefer MUM: python -m pytest -m "hardware and mum" -v
+python -m pytest -m "hardware and babylin" -v
+```
+
+### 3. Full System Testing

+
+## Owon Power Supply (PSU) Integration
+
+The framework includes a serial SCPI controller for Owon PSUs and a hardware test wired to the central config.
+
+- Library: `ecu_framework/power/owon_psu.py` (pyserial)
+- Config: `config/test_config.yaml` (`power_supply` section)
+  - Optionally merge machine-specific settings from `config/owon_psu.yaml` or env `OWON_PSU_CONFIG`
+- Hardware test: `tests/hardware/test_owon_psu.py` (skips unless `power_supply.enabled` and `port` present)
+- quick demo: `vendor/Owon/owon_psu_quickdemo.py`
+
+Quick run:
+
+```powershell
+pip install -r .\requirements.txt
+copy .\config\owon_psu.example.yaml .\config\owon_psu.yaml
+# edit COM port in .\config\owon_psu.yaml
+pytest -k test_owon_psu_idn_and_optional_set -m hardware -q
+python .\vendor\Owon\owon_psu_quick_demo.py
+```
+
+Common config keys:
+
+```yaml
+power_supply:
+  enabled: true
+  port: COM4
+  baudrate: 115200
+  timeout: 1.0
+  eol: "\n"
+  parity: N
+  stopbits: 1
+  idn_substr: OWON
+```
+
+## Next Steps
+
+1. **Hardware Testing**: Connect MUM hardware (or, for legacy rigs, BabyLin) and validate the corresponding hardware smoke tests
+2. **ECU Integration**: Define ECU-specific communication protocols and diagnostic commands
+3. **Hex Flashing**: Implement complete hex file flashing workflow
+4. **CI/CD Integration**: Set up automated testing pipeline with generated reports
+
+## Dependencies

+pytest>=8.4.2
+pytest-html>=4.1.1
+pytest-xdist>=3.8.0
+pyyaml>=6.0.2
+```
+
+This framework provides a complete, production-ready testing solution for ECU development. The current LIN path uses the MUM adapter; the BabyLIN adapter is retained as a deprecated fallback for legacy rigs. Enhanced documentation, traceability, and reporting are available regardless of the adapter in use.

+# Run Sequence: What Happens When You Start Tests
+
+This document walks through the exact order of operations when you run the framework with pytest, what gets called, and where configuration/data is fetched from.
+
+## High-level flow
+
+1. You run pytest from PowerShell
+2. pytest reads `pytest.ini` and loads configured plugins (including our custom `conftest_plugin`)
+3. Test discovery collects tests under `tests/`
+4. Session fixtures run:
+   - `config()` loads YAML configuration
+   - `lin()` selects and connects the LIN interface (Mock, MUM, or the deprecated BabyLIN)
+   - `flash_ecu()` optionally flashes the ECU (if enabled)
+5. Tests execute using fixtures and call interface methods
+6. Our plugin extracts test metadata (Title, Requirements, Steps) from docstrings
+7. Reports are written to `reports/report.html` and `reports/junit.xml`
+

+## Where information is fetched from
+
+- pytest configuration: `pytest.ini`
+- YAML config (default): `config/test_config.yaml`
+- YAML override via env var: `ECU_TESTS_CONFIG`
+- BabyLIN SDK wrapper and SDF path (DEPRECATED): `interface.sdf_path` and `interface.schedule_nr` in YAML
+- Test metadata: parsed from each test’s docstring
+- Markers: declared in `pytest.ini`, attached in tests via `@pytest.mark.*`
+
+## Key components involved
+
+- `tests/conftest.py`: defines `config`, `lin`, and `flash_ecu` fixtures
+- `ecu_framework/config.py`: loads and merges configuration into dataclasses
+- `ecu_framework/lin/base.py`: abstract LIN interface contract and frame shape
+- `ecu_framework/lin/mock.py`: mock behavior for send/receive/request
+- `ecu_framework/lin/mum.py`: MUM adapter (Melexis Universal Master via pylin + pymumclient)
+- `ecu_framework/lin/babylin.py`: BabyLIN SDK wrapper adapter (DEPRECATED real hardware path via BabyLIN_library.py; emits `DeprecationWarning` on use)
+- `ecu_framework/flashing/hex_flasher.py`: placeholder flashing logic
+- `conftest_plugin.py`: report customization and metadata extraction
+
+## Edge cases and behavior
+
+- If `interface.type` is `babylin` (deprecated) but the SDK wrapper or libraries cannot be loaded, hardware tests are skipped
+- If `interface.type` is `mum` but `pylin` / `pymumclient` aren't importable, or `interface.host` is unset, hardware tests are skipped with a clear message
+- If `flash.enabled` is true but `hex_path` is missing, flashing fixture skips
+- Timeouts are honored in `receive()` and `request()` implementations
+- Invalid frame IDs (outside 0x00–0x3F) or data > 8 bytes will raise in `LinFrame`
+- MUM `receive()` is master-driven: it requires a frame ID; `receive(id=None)` raises NotImplementedError. Diagnostic frames needing LIN 1.x Classic checksum should use `MumLinInterface.send_raw()`.

+# Configuration Resolution: What is read and when
+
+This document explains how configuration is loaded, merged, and provided to tests and interfaces.
+
+## Sources and precedence
+
+From highest to lowest precedence:
+
+1. In-code overrides (if `load_config(..., overrides=...)` is used)
+2. Environment variable `ECU_TESTS_CONFIG` (absolute/relative path to YAML)
+3. `config/test_config.yaml` (if present under the workspace root)
+4. Built-in defaults
+
+## Data model (dataclasses)
+
+- `EcuTestConfig`
+  - `interface: InterfaceConfig`
+    - `type`: `mock`, `mum`, or `babylin` (deprecated)
+    - `channel`: LIN channel index (0-based in SDK wrapper) — BabyLIN-specific (deprecated)
+    - `bitrate`: LIN baudrate (e.g., 19200). The MUM uses this directly; BabyLIN typically takes it from the SDF (deprecated path)
+    - `sdf_path`: Path to SDF file (BabyLIN; deprecated — required for typical BabyLIN operation)
+    - `schedule_nr`: Schedule number to start on connect (BabyLIN; deprecated). `-1` = skip
+    - `node_name`: Optional node identifier (informational)
+    - `dll_path`, `func_names`: Deprecated legacy fields from the old ctypes adapter; not used with the SDK wrapper
+    - `host`: MUM IP address (MUM-only). Required when `type: mum`
+    - `lin_device`: MUM LIN device name (MUM-only, default `lin0`)
+    - `power_device`: MUM power-control device (MUM-only, default `power_out0`)
+    - `boot_settle_seconds`: Delay after MUM power-up before sending the first frame (default 0.5)
+    - `frame_lengths`: Optional `{frame_id: data_length}` map for the MUM adapter to drive slave-published reads. Hex keys like `0x0A` are supported in YAML. When `ldf_path` is set, this acts as an override on top of LDF-derived lengths.
+    - `ldf_path`: Optional path to a `.ldf` file. Tests can request the `ldf` fixture to obtain an `LdfDatabase` for per-frame `pack`/`unpack`; the MUM adapter additionally inherits frame lengths from the LDF. Relative paths resolve against the workspace root
+  - `flash: FlashConfig`
+    - `enabled`: whether to flash before tests
+    - `hex_path`: path to HEX file
+  - `power_supply: PowerSupplyConfig`
+    - `enabled`: whether PSU features/tests are active
+    - `port`: Serial device (e.g., `COM4`, `/dev/ttyUSB0`)
+    - `baudrate`, `timeout`, `eol`: line settings (e.g., `"\n"` or `"\r\n"`)
+    - `parity`: `N|E|O`
+    - `stopbits`: `1` or `2`
+    - `xonxoff`, `rtscts`, `dsrdtr`: flow control flags
+    - `idn_substr`: optional substring to assert in `*IDN?`
+    - `do_set`, `set_voltage`, `set_current`: optional demo/test actions
+
+## YAML examples
+
+Minimal mock configuration (default):
+
+```yaml
+interface:
+  type: mock
+  channel: 1
+  bitrate: 19200
+flash:
+  enabled: false
+```
+
+Hardware via MUM (current default) — see also `config/mum.example.yaml`:
+
+```yaml
+interface:
+  type: mum
+  host: 192.168.7.2          # MUM IP address (USB-RNDIS default)
+  lin_device: lin0           # MUM LIN device name
+  power_device: power_out0   # MUM power-control device
+  bitrate: 19200             # LIN baudrate
+  boot_settle_seconds: 0.5   # Delay after power-up before first frame
+  frame_lengths:
+    0x0A: 8                  # ALM_Req_A
+    0x11: 4                  # ALM_Status
+flash:
+  enabled: false
+```
+
+Hardware (BabyLIN SDK wrapper) configuration — DEPRECATED, prefer the MUM example above:
+
+```yaml
+interface:
+  type: babylin           # deprecated
+  channel: 0                    # 0-based channel index
+  bitrate: 19200                # optional; typically driven by SDF
+  node_name: "ECU_TEST_NODE"
+  sdf_path: "./vendor/Example.sdf"
+  schedule_nr: 0
+flash:
+  enabled: true
+  hex_path: "firmware/ecu_firmware.hex"
+
+Power supply configuration (either inline or merged from a dedicated YAML):
+
+```yaml
+power_supply:
+  enabled: true
+  port: COM4           # or /dev/ttyUSB0 on Linux
+  baudrate: 115200
+  timeout: 1.0
+  eol: "\n"          # or "\r\n" if your device requires CRLF
+  parity: N            # N|E|O
+  stopbits: 1          # 1|2
+  xonxoff: false
+  rtscts: false
+  dsrdtr: false
+  idn_substr: OWON
+  do_set: false
+  set_voltage: 5.0
+  set_current: 0.1
+```
+```
+
+## Load flow
+
+```text
+tests/conftest.py: config() fixture
+  → load_config(workspace_root)
+    → check env var ECU_TESTS_CONFIG
+    → else check config/test_config.yaml
+    → else use defaults
+  → convert dicts to EcuTestConfig dataclasses
+  → provide to other fixtures/tests
+
+Additionally, if present, a dedicated PSU YAML is merged into `power_supply`:
+
+- Environment variable `OWON_PSU_CONFIG` (path to YAML), else
+- `config/owon_psu.yaml` under the workspace root
+
+This lets you keep machine-specific serial settings separate while still having
+central defaults in `config/test_config.yaml`.
+```
+
+## How tests and adapters consume config
+
+- `lin` fixture picks `mock`, `mum`, or `babylin` (deprecated) based on `interface.type`
+- Mock adapter uses `bitrate` and `channel` to simulate timing/behavior
+- MUM adapter uses `host`, `lin_device`, `power_device`, `bitrate`, `boot_settle_seconds`, and `frame_lengths` to open the MUM, set up the LIN bus, and power up the ECU on connect
+- BabyLIN adapter (SDK wrapper, **DEPRECATED**) uses `sdf_path`, `schedule_nr`, `channel` to open the device, load the SDF, and start a schedule. `bitrate` is informational unless explicitly applied via commands/SDF. Selecting `interface.type: babylin` emits a `DeprecationWarning`.
+- `flash_ecu` uses `flash.enabled` and `flash.hex_path`
+- PSU-related tests or utilities read `config.power_supply` for serial parameters
+  and optional actions (IDN assertions, on/off toggle, set/measure). The reference
+  implementation is `ecu_framework/power/owon_psu.py`, with a hardware test in
+  `tests/hardware/test_owon_psu.py` and a quick demo script in `vendor/Owon/owon_psu_quick_demo.py`.
+
+## Tips
+
+- Keep multiple YAMLs and switch via `ECU_TESTS_CONFIG`
+- Check path validity for `sdf_path` and `hex_path` before running hardware tests
+- For the deprecated BabyLIN path only: ensure `vendor/BabyLIN_library.py` and the platform-specific libraries from the SDK are available on `PYTHONPATH`
+- Use environment-specific YAML files for labs vs. CI
+- For PSU, prefer `OWON_PSU_CONFIG` or `config/owon_psu.yaml` to avoid committing
+  local COM port settings. Central defaults can live in `config/test_config.yaml`.

+# Reporting and Metadata: How your docs show up in reports
+
+This document describes how test documentation is extracted and rendered into the HTML report, and what appears in JUnit XML.
+
+## What the plugin does
+
+File: `conftest_plugin.py`
+
+- Hooks into `pytest_runtest_makereport` to parse the test’s docstring
+- Extracts the following fields:
+  - Title
+  - Description
+  - Requirements
+  - Test Steps
+  - Expected Result
+- Attaches them as `user_properties` on the test report
+- Customizes the HTML results table to include Title and Requirements columns
+
+## Docstring format to use
+
+```python
+"""
+Title: Short, human-readable test name
+
+Description: What is this test proving and why does it matter.
+
+Requirements: REQ-001, REQ-00X
+
+Test Steps:
+1. Describe the first step
+2. Next step
+3. etc.
+
+Expected Result:
+- Primary outcome
+- Any additional acceptance criteria
+"""
+```
+
+## What appears in reports
+
+- HTML (`reports/report.html`):
+  - Title and Requirements appear as columns in the table
+  - Other fields are available in the report payload and can be surfaced with minor tweaks
+- JUnit XML (`reports/junit.xml`):
+  - Standard test results and timing
+  - Note: By default, the XML is compact and does not include custom properties; if you need properties in XML, we can extend the plugin to emit a custom JUnit format or produce an additional JSON artifact for traceability.
+
+Open the HTML report on Windows PowerShell:
+
+```powershell
+start .\reports\report.html
+```
+
+Related artifacts written by the plugin:
+- `reports/requirements_coverage.json` — requirement → test nodeids map and unmapped tests
+- `reports/summary.md` — compact pass/fail/error/skip totals, environment info
+
+To generate separate HTML/JUnit reports for unit vs non-unit test sets, use the helper script:
+
+```powershell
+./scripts/run_two_reports.ps1
+```
+
+## Parameterized tests and metadata
+
+When using `@pytest.mark.parametrize`, each parameter set is treated as a distinct test case with its own nodeid, e.g.:
+
+```
+tests/test_babylin_wrapper_mock.py::test_babylin_master_request_with_mock_wrapper[wrapper0-True]
+tests/test_babylin_wrapper_mock.py::test_babylin_master_request_with_mock_wrapper[wrapper1-False]
+```
+
+Metadata handling:
+- The docstring on the test function is parsed once per case; the same Title/Requirements are attached to each parameterized instance.
+- Requirement mapping (coverage JSON) records each parameterized nodeid under the normalized requirement keys, enabling fine-grained coverage.
+- In the HTML table, you will see a row per parameterized instance with identical Title/Requirements but differing nodeids (and potentially differing outcomes if parameters influence behavior).
+
+## Markers
+
+Declared in `pytest.ini` and used via `@pytest.mark.<name>` in tests. They also appear in the HTML payload for each test (as user properties) and can be added as a column with a small change if desired.
+
+## Extensibility
+
+- Add more columns to HTML by updating `pytest_html_results_table_header/row`
+- Persist full metadata (steps, expected) to a JSON file after the run for audit trails
+- Populate requirement coverage map by scanning markers and aggregating results
+
+## Runtime properties (record_property) and the `rp` helper fixture
+
+Beyond static docstrings, you can attach dynamic key/value properties during a test.
+
+- Built-in: `record_property("key", value)` in any test
+- Convenience: use the shared `rp` fixture which wraps `record_property` and also prints a short line to captured output for quick scanning.
+
+Example usage:
+
+```python
+def test_example(rp):
+  rp("device", "mock")
+  rp("tx_id", "0x12")
+  rp("rx_present", True)
+```
+
+Where they show up:
+- HTML report: expand a test row to see a Properties table listing all recorded key/value pairs
+- Captured output: look for lines like `[prop] key=value` emitted by the `rp` helper
+
+Suggested standardized keys across suites live in `docs/15_report_properties_cheatsheet.md`.

+# LIN Interface Call Flow
+
+This document explains how LIN operations flow through the abstraction for the Mock, MUM, and the deprecated BabyLIN adapters.
+
+## Contract (base)
+
+File: `ecu_framework/lin/base.py`
+
+- `connect()` / `disconnect()`
+- `send(frame: LinFrame)`
+- `receive(id: int | None = None, timeout: float = 1.0) -> LinFrame | None`
+- `request(id: int, length: int, timeout: float = 1.0) -> LinFrame | None`
+- `flush()`
+
+`LinFrame` validates:
+- ID is 0x00–0x3F (6-bit LIN ID)
+- Data length ≤ 8 bytes
+
+## Mock adapter flow
+
+File: `ecu_framework/lin/mock.py`
+
+- `connect()`: initialize buffers and state
+- `send(frame)`: enqueues the frame and (for echo behavior) schedules it for RX
+- `receive(timeout)`: waits up to timeout for a frame in RX buffer
+- `request(id, length, timeout)`: synthesizes a deterministic response of the given length for predictability
+- `disconnect()`: clears state
+
+Use cases:
+- Fast local dev, deterministic responses, no hardware
+- Timeout and boundary behavior validation
+
+## MUM adapter flow (Melexis Universal Master)
+
+File: `ecu_framework/lin/mum.py`
+
+The MUM is a networked LIN master (default IP `192.168.7.2`) with built-in
+power control on `power_out0`. It is **master-driven**: there is no passive
+listen — to read a slave-published frame, the master triggers a header on
+that frame ID. Diagnostic frames (BSM-SNPD, service ID 0xB5) require LIN 1.x
+**Classic** checksum and are sent through the transport layer's
+`ld_put_raw`, not the regular `send_message`.
+
+- `connect()`: lazy-imports `pymumclient` + `pylin`; opens MUM
+  (`MelexisUniversalMaster.open_all(host)`), gets the LIN device
+  (`linmaster`) and power device (`power_control`), runs `linmaster.setup()`,
+  builds `LinBusManager` + `LinDevice22`, sets `lin_dev.baudrate`, fetches
+  the transport layer (`get_device("bus/transport_layer")`), and finally
+  `power_control.power_up()` followed by a `boot_settle_seconds` sleep
+- `send(frame)`: `lin_dev.send_message(master_to_slave=True, frame_id, data_length, data)`
+- `receive(id, timeout)`: `lin_dev.send_message(master_to_slave=False, frame_id=id, data_length=frame_lengths.get(id, default_data_length))`
+  — pylin returns the response bytes (or raises on timeout, which we treat as `None`).
+  `id=None` raises `NotImplementedError` because the MUM cannot listen passively.
+- `disconnect()`: best-effort `power_control.power_down()` followed by `linmaster.teardown()`
+- MUM-only extras: `send_raw(bytes)` (Classic checksum via `ld_put_raw`),
+  `power_up()`, `power_down()`, `power_cycle(wait)`
+
+Configuration:
+
+- `interface.host` is required; `interface.lin_device` and `interface.power_device` default to MUM conventions
+- `interface.bitrate` is the actual LIN baudrate the MUM drives
+- `interface.frame_lengths` lets you map slave frame IDs to their fixed data lengths so `receive(id)` can fetch the correct number of bytes; built-in defaults cover ALM_Status (4) and ALM_Req_A (8)
+
+## BabyLIN adapter flow (SDK wrapper) — DEPRECATED
+
+> Retained only so existing BabyLIN rigs can keep running. New work should use the MUM flow above.
+
+File: `ecu_framework/lin/babylin.py` (emits `DeprecationWarning` on instantiation)
+
+- `connect()`: import SDK `BabyLIN_library.py`, discover ports, open first, optionally `BLC_loadSDF`, get channel handle, and `BLC_sendCommand("start schedule N;")`
+- `send(frame)`: calls `BLC_mon_set_xmit(channelHandle, frameId, data, slotTime=0)`
+- `receive(timeout)`: calls `BLC_getNextFrameTimeout(channelHandle, timeout_ms)` and converts returned `BLC_FRAME` to `LinFrame`
+- `request(id, length, timeout)`: prefers `BLC_sendRawMasterRequest(channel, id, length)`; falls back to `(channel, id, bytes)`; if unavailable, sends a header and waits on `receive()`
+- `disconnect()`: calls `BLC_closeAll()`
+- Error handling: uses `BLC_getDetailedErrorString` (if available)
+
+Configuration:
+- `interface.sdf_path` locates the SDF to load
+- `interface.schedule_nr` sets the schedule to start upon connect
+- `interface.channel` selects the channel index
+
+## Edge considerations
+
+- Ensure the correct architecture (x86/x64) of the DLL matches Python
+- Channel/bitrate must match your network configuration
+- Some SDKs require initialization/scheduling steps before transmit/receive
+- Time synchronization and timestamp units vary per SDK — convert as needed
+
+Note on master requests:
+- Our mock wrapper returns a deterministic byte pattern when called with the `length` signature.
+- When only the bytes signature is available, zeros of the requested length are used in tests.

+## Data and control flow summary
+
+- Tests use fixtures to obtain config and a connected LIN adapter
+- Config loader reads YAML (or env override), returns typed dataclasses
+- LIN calls are routed through the interface abstraction to the selected adapter
+- Hardware tests sit on top of two helpers: `FrameIO` (LDF-driven send /
+  receive / pack / unpack for any frame) and `AlmTester` (ALM_Node domain
+  patterns built on `FrameIO`). Both are imported as siblings from
+  `tests/hardware/` — see `docs/19_frame_io_and_alm_helpers.md`
+- The hardware-suite `tests/hardware/conftest.py` defines a **session-scoped,
+  autouse** `psu` fixture: on benches where the Owon PSU powers the ECU,
+  the supply is opened once at session start, parked at
+  `config.power_supply.set_voltage` / `set_current`, and left enabled
+  for every test. Voltage-tolerance tests perturb voltage and restore
+  in `finally`; they never toggle output. See `docs/14_power_supply.md` §5.
+- Flasher (optional) uses the same `LinInterface` to program the ECU
+- Power supply control (optional) uses `ecu_framework/power/owon_psu.py`
+  and reads `config.power_supply` (merged with `config/owon_psu.yaml`
+  or `OWON_PSU_CONFIG` when present). The quick demo script under
+  `vendor/Owon/` provides a quick manual flow
+- Reporting plugin parses docstrings and enriches the HTML report
+
+## Extending the architecture
+
+- Add new bus adapters by implementing `LinInterface`
+- Add new ECU-domain helpers next to `AlmTester` (e.g. `BcmTester`)
+  on top of `FrameIO`; share fixtures via `tests/hardware/conftest.py`
+- Add new bench instrument controllers next to `OwonPSU` under
+  `ecu_framework/power/` or a new `ecu_framework/instruments/` package,
+  expose them as session-scoped fixtures
+- Add new report sinks (e.g., JSON or a DB) by extending the plugin

+# Requirement Traceability
+
+This document shows how requirements map to tests via pytest markers and docstrings, plus how to visualize coverage.
+
+## Conventions
+
+- Requirement IDs: `REQ-xxx`
+- Use markers in tests: `@pytest.mark.req_001`, `@pytest.mark.req_002`, etc.
+- Include readable requirement list in the test docstring under `Requirements:`
+
+## Example
+
+```python
+@pytest.mark.req_001

+# Flashing Sequence (ECU Programming)
+
+This document outlines the expected flashing workflow using the `HexFlasher` scaffold over the LIN interface and where you can plug in your production flasher (UDS).
+
+## Overview
+
+- Flashing is controlled by configuration (`flash.enabled`, `flash.hex_path`)
+- The `flash_ecu` session fixture invokes the flasher before tests
+- The flasher uses the same `LinInterface` as tests
+
+## Mermaid sequence
+
+```mermaid

+  participant P as pytest
+  participant F as flash_ecu fixture
+  participant H as HexFlasher
+  participant L as LinInterface (mock/mum/babylin — babylin deprecated)
+  participant E as ECU
+
+  P->>F: Evaluate flashing precondition
+  alt flash.enabled == true and hex_path provided
+    F->>H: HexFlasher(lin).flash_hex(hex_path)
+    H->>L: connect (ensure session ready)

+    H->>E: Exit programming, reset if needed
+    H-->>F: Return success/failure
+  else
+    F-->>P: Skip flashing

+
+## Implementation notes
+
+- `ecu_framework/flashing/hex_flasher.py` is a stub — replace with your protocol implementation (UDS)
+- Validate timing requirements and chunk sizes per ECU
+- Consider power-cycle/reset hooks via programmable poewr supply.
+
+## Error handling
+
+- On failure, the fixture calls `pytest.fail("ECU flashing failed")`
+- Make flashing idempotent when possible (can retry or detect current version)
+
+## Configuration example
+
+```yaml
+flash:
+  enabled: true
+  hex_path: "firmware/ecu_firmware.hex"

+# BabyLIN Adapter Internals (SDK Python wrapper)
+
+> **Status: DEPRECATED.** The BabyLIN adapter is retained for backward compatibility only. New tests and deployments should target the MUM (Melexis Universal Master) adapter — see `16_mum_internals.md`. This document is kept so existing BabyLIN setups can still be maintained.
+
+This document describes how the real hardware adapter binds to the BabyLIN SDK via the official Python wrapper `BabyLIN_library.py` and how frames move across the boundary.
+
+## Overview
+
+- Location: `ecu_framework/lin/babylin.py`
+- Uses the SDK's `BabyLIN_library.py` (place under `vendor/` or on `PYTHONPATH`)
+- Discovers and opens a BabyLIN device using `BLC_getBabyLinPorts` and `BLC_openPort`
+- Optionally loads an SDF via `BLC_loadSDF(handle, sdf_path, 1)` and starts a schedule with `BLC_sendCommand("start schedule N;")`
+- Converts between Python `LinFrame` and the wrapper's `BLC_FRAME` structure for receive

+  L->>L: convert BLC_FRAME to LinFrame
+  L-->>T: LinFrame or None
+
+  T->>L: disconnect()
+  L->>D: BLC_closeAll()
+```
+
+## Master request behavior
+
+When performing a master request, the adapter tries the SDK method in this order:
+
+1. `BLC_sendRawMasterRequest(channel, id, length)` — preferred
+2. `BLC_sendRawMasterRequest(channel, id, dataBytes)` — fallback
+3. Send a header with zeros and wait on `receive()` — last resort
+
+Mock behavior notes:
+- The provided mock (`vendor/mock_babylin_wrapper.py`) synthesizes a deterministic response for the `length` signature (e.g., data[i] = (id + i) & 0xFF).
+- For the bytes-only signature, the adapter sends zero-filled bytes of the requested length and validates by length.
+## Wrapper usage highlights
+
+```python
+from BabyLIN_library import create_BabyLIN
+
+bl = create_BabyLIN()
+ports = bl.BLC_getBabyLinPorts(100)
+h = bl.BLC_openPort(ports[0])
+bl.BLC_loadSDF(h, "Example.sdf", 1)
+ch = bl.BLC_getChannelHandle(h, 0)
+bl.BLC_sendCommand(ch, "start schedule 0;")
+
+# Transmit and receive
+bl.BLC_mon_set_xmit(ch, 0x10, bytes([1,2,3,4]), 0)
+frm = bl.BLC_getNextFrameTimeout(ch, 100)
+print(frm.frameId, list(frm.frameData)[:frm.lenOfData])
+
+bl.BLC_closeAll()
+```
+
+## Notes and pitfalls
+
+- Architecture: Ensure Python (x86/x64) matches the platform library bundled with the SDK
+- Timeouts: SDKs typically want milliseconds; convert Python seconds accordingly
+- Error handling: On non-zero return codes, use `BLC_getDetailedErrorString` (if available) for human-readable messages
+- Threading: If you use background receive threads, protect buffers with locks
+- Performance: Avoid excessive allocations in tight loops; reuse frame structs when possible
+
+## Extending
+
+- Add bitrate/channel setup functions as exposed by the SDK
+- Implement schedule tables or diagnostics passthrough if provided by the SDK
+- Wrap more SDK errors into typed Python exceptions for clarity

+# Raspberry Pi Deployment Guide
+
+This guide explains how to run the ECU testing framework on a Raspberry Pi (Debian/Raspberry Pi OS). It covers environment setup, hardware integration via MUM (recommended) or the deprecated BabyLin (legacy rigs only), running tests headless, and installing as a systemd service.
+
+> Note: The MUM (Melexis Universal Master) is **networked**, so the Pi only
+> needs IP reachability to the MUM (default `192.168.7.2`) — there are no
+> Pi-side native libs to worry about. BabyLin (deprecated) needs ARM Linux
+> native libraries; if those aren't available, use Mock or MUM on the Pi
+> instead. New deployments should not target BabyLin.
+
+## 1) Choose your interface
+
+- **MUM (recommended for hardware on Pi)**: `interface.type: mum`. Requires Melexis `pylin` + `pymumclient` (see `vendor/automated_lin_test/install_packages.sh`) and IP reachability to the MUM device.
+- Mock (recommended for headless/dev on Pi): `interface.type: mock`
+- BabyLIN (**DEPRECATED** — only for legacy rigs and only if ARM/Linux support is available): `interface.type: babylin` and ensure the SDK's `BabyLIN_library.py` and corresponding Linux/ARM shared libraries are available under `vendor/` or on PYTHONPATH/LD_LIBRARY_PATH. Selecting this path emits a `DeprecationWarning`.
+
+## 2) Install prerequisites
+
+```bash
+sudo apt update
+sudo apt install -y python3 python3-venv python3-pip git
+```
+
+Optional (for the deprecated BabyLin path or USB tools):
+```bash
+sudo apt install -y libusb-1.0-0 udev
+```
+
+## 3) Clone and set up
+
+```bash
+# clone your repo
+git clone <your-repo-url> ~/ecu_tests
+cd ~/ecu_tests
+
+# create venv
+python3 -m venv .venv
+source .venv/bin/activate
+
+# install deps
+pip install -r requirements.txt
+```
+
+## 4) Configure
+
+Create or edit `config/test_config.yaml`:
+
+```yaml
+interface:
+  type: mock   # or "mum" for hardware (current); "babylin" is deprecated
+  channel: 1
+  bitrate: 19200
+flash:
+  enabled: false
+```
+
+Optionally point to another config file via env var:
+```bash
+export ECU_TESTS_CONFIG=$(pwd)/config/test_config.yaml
+```
+
+If using the MUM on the Pi, set:
+
+```yaml
+interface:
+  type: mum
+  host: 192.168.7.2          # adjust to your MUM IP
+  lin_device: lin0
+  power_device: power_out0
+  bitrate: 19200
+  boot_settle_seconds: 0.5
+  frame_lengths:
+    0x0A: 8
+    0x11: 4
+```
+
+Confirm reachability before running tests:
+
+```bash
+ping -c 2 192.168.7.2
+```
+
+If using BabyLIN on Linux/ARM with the SDK wrapper (**DEPRECATED**, legacy rigs only), set:
+
+```yaml
+interface:
+  type: babylin            # deprecated; prefer "mum"
+  channel: 0
+  sdf_path: "/home/pi/ecu_tests/vendor/Example.sdf"
+  schedule_nr: 0
+```
+
+## 5) Run tests on Pi
+
+```bash
+source .venv/bin/activate
+python -m pytest -m "not hardware" -v
+```
+
+Artifacts are in `reports/` (HTML, JUnit, JSON, summary MD).
+
+## 6) Run as a systemd service (headless)
+
+This section lets the Pi run the test suite on boot or on demand.
+
+### Create a runner script
+
+Create `scripts/run_tests.sh`:
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+cd "$(dirname "$0")/.."
+source .venv/bin/activate
+# optionally set custom config
+# export ECU_TESTS_CONFIG=$(pwd)/config/test_config.yaml
+python -m pytest -v
+```
+Make it executable:
+```bash
+chmod +x scripts/run_tests.sh
+```
+
+### Create a systemd unit
+
+Create `scripts/ecu-tests.service`:
+```ini
+[Unit]
+Description=ECU Tests Runner
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=oneshot
+WorkingDirectory=/home/pi/ecu_tests
+ExecStart=/home/pi/ecu_tests/scripts/run_tests.sh
+User=pi
+Group=pi
+Environment=ECU_TESTS_CONFIG=/home/pi/ecu_tests/config/test_config.yaml
+# Capture output to a log file
+StandardOutput=append:/home/pi/ecu_tests/reports/service.log
+StandardError=append:/home/pi/ecu_tests/reports/service.err
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Install and run:
+```bash
+sudo mkdir -p /home/pi/ecu_tests/reports
+sudo cp scripts/ecu-tests.service /etc/systemd/system/ecu-tests.service
+sudo systemctl daemon-reload
+sudo systemctl enable ecu-tests.service
+# Start manually
+sudo systemctl start ecu-tests.service
+# Check status
+systemctl status ecu-tests.service
+```
+
+## 7) USB and permissions (if using hardware)
+
+- Create udev rules for your device (if required by vendor)
+- Add user to dialout or plugdev groups if serial/USB access is needed
+- Confirm your hardware library is found by Python and the dynamic linker:
+  - For the deprecated BabyLIN path only: ensure `vendor/BabyLIN_library.py` is importable (add `vendor/` to PYTHONPATH if needed)
+  - Ensure `.so` files are discoverable (e.g., place in `/usr/local/lib` and run `sudo ldconfig`, or set `LD_LIBRARY_PATH`)
+
+## 8) Tips
+
+- Use the mock interface on Pi for quick smoke tests and documentation/report generation
+- For full HIL on Pi, the **MUM is the easiest path** — it's IP-reachable so the Pi doesn't need vendor-specific native libraries, just the Melexis Python packages (`pylin`, `pymumclient`)
+- For the deprecated BabyLIN HIL path, ensure vendor SDK supports Linux/ARM and provide a shared object (`.so`) and headers — but prefer migrating these rigs to MUM
+- If only Windows is supported by your hardware path, run the hardware suite on a Windows host and use the Pi for lightweight tasks (archiving, reporting, quick checks)

+# Build a Custom Raspberry Pi Image with ECU Tests
+
+This guide walks you through building your own Raspberry Pi OS image that already contains this framework, dependencies, config, and services. It uses the official pi-gen tool (used by Raspberry Pi OS) or the simpler pi-gen-lite alternatives.
+
+> Important: For full HIL on the Pi, the **MUM (Melexis Universal Master)** is
+> the recommended hardware path — it's IP-reachable so the Pi only needs the
+> Melexis Python packages (`pylin`, `pymumclient`), no native libraries. Bake
+> those into the image's site-packages from the Melexis IDE bundle. BabyLin
+> is **deprecated**; its support on ARM/Linux depends on vendor SDKs and is
+> kept only for legacy rigs. If no `.so` is provided for ARM, either use the
+> Mock or MUM interface on the Pi, or keep deprecated BabyLIN hardware tests
+> on Windows until you can migrate.
+
+## Approach A: Using pi-gen (official)
+
+1. Prepare a build host (Debian/Ubuntu)
+   ```bash
+   sudo apt update && sudo apt install -y git coreutils quilt parted qemu-user-static debootstrap zerofree \
+     pxz zip dosfstools libcap2-bin grep rsync xz-utils file bc curl jq
+   ```
+2. Clone pi-gen
+   ```bash
+   git clone https://github.com/RPi-Distro/pi-gen.git
+   cd pi-gen
+   ```
+3. Create a custom stage for ECU Tests (e.g., `stage2/02-ecu-tests/`):
+   - `00-packages` (optional OS deps like python3, libusb-1.0-0)
+   - `01-run.sh` to clone your repo, create venv, install deps, and set up systemd units
+
+   Example `01-run.sh` contents:
+   ```bash
+   #!/bin/bash -e
+   REPO_DIR=/home/pi/ecu_tests
+   sudo -u pi git clone <your-repo-url> "$REPO_DIR"
+   cd "$REPO_DIR"
+   sudo -u pi python3 -m venv .venv
+   sudo -u pi bash -lc "source .venv/bin/activate && pip install --upgrade pip && pip install -r requirements.txt"
+   sudo mkdir -p "$REPO_DIR/reports"
+   sudo chown -R pi:pi "$REPO_DIR/reports"
+   sudo install -Dm644 "$REPO_DIR/scripts/ecu-tests.service" /etc/systemd/system/ecu-tests.service
+   sudo install -Dm644 "$REPO_DIR/scripts/ecu-tests.timer" /etc/systemd/system/ecu-tests.timer
+   sudo systemctl enable ecu-tests.service
+   sudo systemctl enable ecu-tests.timer || true
+   # Optional udev rules (DEPRECATED: only needed for legacy BabyLIN hardware)
+   if [ -f "$REPO_DIR/scripts/99-babylin.rules" ]; then
+     sudo install -Dm644 "$REPO_DIR/scripts/99-babylin.rules" /etc/udev/rules.d/99-babylin.rules
+   fi
+   ```
+4. Configure build options (`config` file in pi-gen root):
+   ```bash
+   IMG_NAME=ecu-tests-os
+   ENABLE_SSH=1
+   STAGE_LIST="stage0 stage1 stage2"  # include your custom stage2 additions
+   ```
+5. Build
+   ```bash
+   sudo ./build.sh
+   ```
+6. Flash the resulting `.img` to SD card with `Raspberry Pi Imager` or `dd`.
+
+## Approach B: Preseed on first boot (lighter)
+
+- Ship a minimal Raspberry Pi OS image and a cloud-init/user-data or first-boot script that pulls your repo and runs `scripts/pi_install.sh`.
+- Pros: Faster iteration; you control repo URL at install time.
+- Cons: Requires internet on first boot.
+
+## CI Integration (optional)
+
+- You can automate image builds with GitHub Actions or GitLab CI using a Docker runner that executes pi-gen.
+- Upload the `.img` as a release asset or pipeline artifact.
+- Optionally, bake environment-specific `config/test_config.yaml` or keep it external and set `ECU_TESTS_CONFIG` in the systemd unit.
+
+## Hardware Notes
+
+- If using the deprecated BabyLin path (legacy rigs), ensure: `.so` for ARM, udev rules, and any kernel modules. New deployments should target MUM instead.
+- Validate the SDK wrapper and libraries are present under `/opt/ecu_tests/vendor/` (or your chosen path). Ensure `.so` files are on the linker path (run `sudo ldconfig`) and `BabyLIN_library.py` is importable.
+
+## Boot-time Behavior
+
+- The `ecu-tests.timer` can schedule daily or hourly test runs; edit `OnUnitActiveSec` as needed.
+- Logs are written to `reports/service.log` and `reports/service.err` on the Pi.
+
+## Security
+
+- Consider read-only root filesystem for robustness.
+- Use a dedicated user with limited privileges for test execution.
+- Keep secrets (if any) injected via environment and not committed.

+# Pytest Plugin: Reporting & Traceability Overview
+
+This guide explains the custom pytest plugin in `conftest_plugin.py` that enriches reports with business-facing metadata and builds requirements traceability artifacts.
+
+## What it does
+
+- Extracts metadata (Title, Description, Requirements, Test Steps, Expected Result) from test docstrings and markers.
+- Attaches this metadata as `user_properties` on each test report.
+- Adds custom columns (Title, Requirements) to the HTML report.
+- Produces two artifacts under `reports/` at the end of the run:
+  - `requirements_coverage.json`: a traceability matrix mapping requirement IDs to test nodeids, plus unmapped tests.
+  - `summary.md`: a compact summary of results suitable for CI dashboards or PR comments.

+- Test docstrings prefixed lines:
+  - `Title:` one-line title
+  - `Description:` free-form text until the next section
+  - `Requirements:` comma- or space-separated tokens such as `REQ-001`, `req_002`
+  - `Test Steps:` numbered list (1., 2., 3., ...)
+  - `Expected Result:` free-form text
+- Pytest markers on tests: `@pytest.mark.req_001` etc. are normalized to `REQ-001`.
+
+## Normalization logic
+
+Requirement IDs are normalized to the canonical form `REQ-XYZ` using:
+- `req_001` → `REQ-001`
+- `REQ-1` / `REQ-001` / `REQ_001` → `REQ-001`
+
+This ensures consistent keys in the coverage JSON and HTML.
+
+## Hook call sequence
+
+Below is the high-level call sequence of relevant plugin hooks during a typical run:
+
+```mermaid

+    Plugin->>Plugin: compile stats, coverage map, unmapped tests
+    Plugin->>FS: write reports/requirements_coverage.json
+    Plugin->>FS: write reports/summary.md
+```
+
+## HTML report integration
+
+- `pytest_html_results_table_header`: inserts Title and Requirements columns.
+- `pytest_html_results_table_row`: fills in values from `report.user_properties`.
+
+The HTML plugin reads `user_properties` to render the extra metadata per test row.
+
+## Artifacts
+
+- `reports/requirements_coverage.json`
+  - `generated_at`: ISO timestamp
+  - `results`: counts of passed/failed/skipped/etc.
+  - `requirements`: map of `REQ-XXX` to an array of test nodeids
+  - `unmapped_tests`: tests with no requirement mapping
+  - `files`: relative locations of key artifacts
+- `reports/summary.md`
+  - Human-readable summary with counts and quick artifact links
+
+## Error handling
+
+Artifact writes are wrapped in try/except to avoid failing the test run if the filesystem is read-only or unavailable. Any write failure is logged to the terminal.
+
+## Extensibility ideas
+
+- Add more normalized marker families (e.g., `capability_*`, `risk_*`).
+- Emit CSV or Excel in addition to JSON/Markdown.
+- Include per-test durations and flakiness stats in the summary.
+- Support a `--requirement` CLI filter that selects tests by normalized req IDs.

+# Using the ECU Test Framework
+
+This guide shows common ways to run the test framework: from fast local mock runs to full hardware loops, CI, and Raspberry Pi deployments. Commands use Windows PowerShell (as your default shell).
+
+## Prerequisites
+
+- Python 3.x and a virtual environment
+- Dependencies installed (see `requirements.txt`)
+- For MUM hardware: Melexis `pylin` and `pymumclient` Python packages on `PYTHONPATH` (see `vendor/automated_lin_test/install_packages.sh`) plus a reachable MUM (default IP `192.168.7.2`)
+- For BabyLIN (**DEPRECATED**, legacy rigs only) hardware: SDK files placed under `vendor/` as described in `vendor/README.md`
+
+## Configuring tests
+
+- Configuration is loaded from YAML files and can be selected via the environment variable `ECU_TESTS_CONFIG`.
+- See `docs/02_configuration_resolution.md` for details and examples.
+
+Example PowerShell:
+
+```powershell
+# Use a mock-only config for fast local runs
+$env:ECU_TESTS_CONFIG = ".\config\mock.yml"
+
+# Use a hardware config with the MUM (current default)
+$env:ECU_TESTS_CONFIG = ".\config\mum.example.yaml"
+
+# Use a hardware config with the BabyLIN SDK wrapper (DEPRECATED, legacy rigs only)
+$env:ECU_TESTS_CONFIG = ".\config\babylin.example.yaml"
+```
+
+Quick try with provided examples:
+
+```powershell
+# Point to the combined examples file
+$env:ECU_TESTS_CONFIG = ".\config\examples.yaml"
+# The 'active' section defaults to the mock profile; run non-hardware tests
+pytest -m "not hardware" -v
+# Edit 'active' to the mum (preferred) or babylin (deprecated) profile, or
+# point to mum.example.yaml / babylin.example.yaml, and run hardware tests
+```
+
+## Running locally (mock interface)
+
+Use the mock interface to develop tests quickly without hardware:
+
+```powershell
+# Run all mock tests with HTML and JUnit outputs (see pytest.ini defaults)
+pytest
+
+# Run only smoke tests (mock) and show progress
+pytest -m smoke -q
+
+# Filter by test file or node id
+pytest tests\test_smoke_mock.py::TestMockLinInterface::test_mock_send_receive_echo -q
+```
+
+What you get:
+- Fast execution, deterministic results
+- Reports in `reports/` (HTML, JUnit, coverage JSON, CI summary)
+
+Open the HTML report on Windows:
+
+```powershell
+start .\reports\report.html
+```
+
+## Running on hardware (MUM — current default)
+
+1) Install Melexis `pylin` and `pymumclient` (see `vendor/automated_lin_test/install_packages.sh` — on Windows, point `pip` at a wheel or extend `PYTHONPATH` to the Melexis IDE site-packages).
+2) Make sure the MUM is reachable: `ping 192.168.7.2`.
+3) Select a config that defines `interface.type: mum` plus `host`/`lin_device`/`power_device`.
+
+```powershell
+$env:ECU_TESTS_CONFIG = ".\config\mum.example.yaml"
+
+# Run only the MUM-marked hardware tests
+pytest -m "hardware and mum" -v
+
+# Run a single MUM test by file
+pytest tests\hardware\test_e2e_mum_led_activate.py -q
+```
+
+Tips:
+- The MUM owns ECU power on `power_out0`; it powers up automatically in `connect()` and powers down on `disconnect()`. The Owon PSU is independent and can be left disabled (`power_supply.enabled: false`).
+- The MUM is master-driven: `lin.receive(id)` requires a frame ID. The default `frame_lengths` covers ALM_Status (4 B) and ALM_Req_A (8 B); add others in YAML when you need slave-published frames at non-standard lengths.
+- For BSM-SNPD diagnostic frames (service ID 0xB5), use `lin.send_raw(bytes)` — it routes through the transport layer's `ld_put_raw`, which uses LIN 1.x **Classic** checksum. `send()` uses Enhanced and the firmware will reject these frames.
+
+## Running on hardware (BabyLIN SDK wrapper — DEPRECATED)
+
+> Retained only so existing BabyLIN rigs can keep running. New work should use the MUM section above. Selecting `interface.type: babylin` emits a `DeprecationWarning`.
+
+1) Place SDK files per `vendor/README.md`.
+2) Select a config that defines `interface.type: babylin`, `sdf_path`, and `schedule_nr`.
+3) Markers allow restricting to hardware tests.
+
+```powershell
+$env:ECU_TESTS_CONFIG = ".\config\babylin.example.yaml"
+
+# Run only hardware tests
+pytest -m "hardware and babylin"
+
+# Run the schedule smoke only
+pytest tests\test_babylin_hardware_schedule_smoke.py -q
+```
+
+Tips:
+- If multiple devices are attached, update your config to select the desired port (future enhancement) or keep only one connected.
+- On timeout, tests often accept None to avoid flakiness; increase timeouts if your bus is slow.
+- Master request behavior: the adapter prefers `BLC_sendRawMasterRequest(channel, id, length)`; it falls back to the bytes variant or a header+receive strategy as needed. The mock covers both forms.
+- `interface.schedule_nr: -1` defers schedule start to the test code (useful when the test wants to pick a specific schedule by name via `lin.start_schedule("CCO")`).
+
+## Selecting tests with markers
+
+Markers in use:
+
+- `smoke`: quick confidence tests
+- `hardware`: needs real device (any LIN master)
+- `mum`: targets the Melexis Universal Master adapter (current default)
+- `babylin`: targets the **deprecated** BabyLIN SDK adapter
+- `unit`: pure unit tests (no hardware, no external I/O)
+- `req_XXX`: requirement mapping (e.g., `@pytest.mark.req_001`)
+
+Examples:
+
+```powershell
+# Only smoke tests (mock + hardware smoke)
+pytest -m smoke
+
+# Requirements-based selection (docstrings and markers are normalized)
+pytest -k REQ-001
+```
+
+## Enriched reporting
+
+- HTML report includes custom columns (Title, Requirements)
+- JUnit XML written for CI
+- `reports/requirements_coverage.json` maps requirement IDs to tests and lists unmapped tests
+- `reports/summary.md` aggregates key counts (pass/fail/etc.)
+
+See `docs/03_reporting_and_metadata.md` and `docs/11_conftest_plugin_overview.md`.
+
+To verify the reporting pipeline end-to-end, run the plugin self-test:
+
+```powershell
+python -m pytest tests\plugin\test_conftest_plugin_artifacts.py -q
+```
+
+To generate two separate HTML/JUnit reports (unit vs non-unit):
+
+```powershell
+./scripts/run_two_reports.ps1
+```
+
+## Writing well-documented tests
+
+Use a docstring template so the plugin can extract metadata:
+
+```python
+"""
+Title: <short title>
+
+Description:
+    <what the test validates and why>
+
+Requirements: REQ-001, REQ-002
+
+Test Steps:
+    1. <step one>
+    2. <step two>
+
+Expected Result:
+    <succinct expected outcome>
+"""
+```
+
+Tip: For runtime properties in reports, prefer the shared `rp` fixture (wrapper around `record_property`) and use standardized keys from `docs/15_report_properties_cheatsheet.md`.
+
+## Continuous Integration (CI)
+
+- Run `pytest` with your preferred markers in your pipeline.
+- Publish artifacts from `reports/` (HTML, JUnit, coverage JSON, summary.md).
+- Optionally parse `requirements_coverage.json` to power dashboards and gates.
+
+Example PowerShell (local CI mimic):
+
+```powershell
+# Run smoke tests and collect reports
+pytest -m smoke --maxfail=1 -q
+```
+
+## Raspberry Pi / Headless usage
+
+- Follow `docs/09_raspberry_pi_deployment.md` to set up a venv and systemd service
+- For a golden image approach, see `docs/10_build_custom_image.md`
+
+Running tests headless via systemd typically involves:
+
+- A service that sets `ECU_TESTS_CONFIG` to a hardware YAML
+- Running `pytest -m "hardware and mum"` (or, for legacy rigs only, `"hardware and babylin"` — deprecated) on boot or via timer
+
+## Troubleshooting quick hits
+
+- ImportError for `pylin` / `pymumclient`: install Melexis packages (`vendor/automated_lin_test/install_packages.sh`); the MUM adapter raises a clear error pointing at this script.
+- "interface.host is required when interface.type == 'mum'": set `interface.host` in YAML.
+- MUM unreachable: `ping 192.168.7.2`; check the USB-RNDIS link.
+- ImportError for `BabyLIN_library` (DEPRECATED path): verify placement under `vendor/` and native library presence. Consider migrating the rig to MUM, which avoids vendor DLLs.
+- No BabyLIN devices found (DEPRECATED): check USB connection, drivers, and permissions.
+- Timeouts on receive: increase `timeout` or verify schedule activity and SDF correctness.
+- Missing reports: ensure `pytest.ini` includes the HTML/JUnit plugins and the custom plugin is loaded.
+
+## Power supply (Owon) hardware test
+
+Enable `power_supply` in your config and set the serial port, then run the dedicated test or the quick demo script.
+
+```powershell
+copy .\config\owon_psu.example.yaml .\config\owon_psu.yaml
+# edit COM port in .\config\owon_psu.yaml or set values in config\test_config.yaml
+
+pytest -k test_owon_psu_idn_and_optional_set -m hardware -q
+python .\vendor\Owon\owon_psu_quick_demo.py
+```
+

+# Unit Testing Guide
+
+This guide explains how the project's unit tests are organized, how to run them (with and without markers), how coverage is generated, and tips for writing effective tests.
+
+## Why unit tests?
+
+- Fast feedback without hardware
+- Validate contracts (config loader, frames, adapters, flashing scaffold)
+- Keep behavior stable as the framework evolves
+
+## Test layout
+
+- `tests/unit/` — pure unit tests (no hardware, no external I/O)
+  - `test_config_loader.py` — config precedence and defaults
+  - `test_linframe.py` — `LinFrame` validation
+  - `test_babylin_adapter_mocked.py` — DEPRECATED BabyLIN adapter error paths with a mocked SDK wrapper
+  - `test_mum_adapter_mocked.py` — MUM adapter (`MumLinInterface`) plumbing exercised through fake `pylin` / `pymumclient` modules
+  - `test_hex_flasher.py` — flashing scaffold against a stub LIN interface
+- `tests/plugin/` — plugin self-tests using `pytester`
+  - `test_conftest_plugin_artifacts.py` — verifies JSON coverage and summary artifacts
+- `tests/` — existing smoke/mock/hardware tests
+
+## Markers and selection
+
+A `unit` marker is provided for easy selection:
+
+- By marker (recommended):
+
+```powershell
+pytest -m unit -q
+```
+
+- By path:
+
+```powershell
+pytest tests\unit -q
+```
+
+- Exclude hardware:
+
+```powershell
+pytest -m "not hardware" -v
+```
+
+## Coverage
+
+Coverage is enabled by default via `pytest.ini` addopts:
+
+- `--cov=ecu_framework --cov-report=term-missing`
+
+You’ll see a summary with missing lines directly in the terminal. To disable coverage locally, override addopts on the command line:
+
+```powershell
+pytest -q -o addopts=""
+```
+
+(Optional) To produce an HTML coverage report, you can add `--cov-report=html` and open `htmlcov/index.html`.
+
+## Writing unit tests
+
+- Prefer small, focused tests
+- For the **deprecated** BabyLIN adapter logic, inject `wrapper_module` with the mock (kept for legacy coverage; new tests should target MUM):
+
+```python
+from ecu_framework.lin.babylin import BabyLinInterface  # DeprecationWarning on use
+from vendor import mock_babylin_wrapper as mock_bl
+
+lin = BabyLinInterface(wrapper_module=mock_bl)
+lin.connect()
+# exercise send/receive/request
+```
+
+- For MUM adapter logic, inject `mum_module` and `pylin_module` with fakes
+  (see `tests/unit/test_mum_adapter_mocked.py` for a full example):
+
+```python
+from ecu_framework.lin.mum import MumLinInterface
+
+# fake_mum exposes MelexisUniversalMaster() returning an object with
+#   open_all(host) and get_device(name)
+# fake_pylin exposes LinBusManager(linmaster) and LinDevice22(lin_bus)
+lin = MumLinInterface(host="10.0.0.1", mum_module=fake_mum, pylin_module=fake_pylin)
+lin.connect()
+# exercise send / receive / send_raw / power_*
+```
+
+- To simulate specific (deprecated) SDK signatures, use a thin shim (see `_MockBytesOnly` in `tests/test_babylin_wrapper_mock.py`).
+- Include a docstring with Title/Description/Requirements/Steps/Expected Result so the reporting plugin can extract metadata (this also helps the HTML report).
+- When testing the plugin itself, use the `pytester` fixture to generate a temporary test run and validate artifacts exist and contain expected entries.
+
+## Typical commands (Windows PowerShell)
+
+- Run unit tests with coverage:
+
+```powershell
+pytest -m unit -q
+```
+
+- Run only plugin self-tests:
+
+```powershell
+pytest tests\plugin -q
+```
+
+- Run the specific plugin artifact test (verifies HTML/JUnit, summary, and coverage JSON under `reports/`):
+
+```powershell
+python -m pytest tests\plugin\test_conftest_plugin_artifacts.py -q
+```
+
+- Run all non-hardware tests with verbose output:
+
+```powershell
+pytest -m "not hardware" -v
+```
+
+- Open the HTML report:
+
+```powershell
+start .\reports\report.html
+```
+
+- Generate two separate reports (unit vs non-unit):
+
+```powershell
+./scripts/run_two_reports.ps1
+```
+
+## CI suggestions
+
+- Run `-m unit` and `tests/plugin` on every PR
+- Optionally run mock integration/smoke on PR
+- Run hardware test matrix on a nightly or on-demand basis (`-m "hardware and mum"`; `-m "hardware and babylin"` is deprecated and only for legacy rigs)
+- Publish artifacts from `reports/`: HTML/JUnit/coverage JSON/summary MD
+
+## Troubleshooting
+
+- Coverage not showing: ensure `pytest-cov` is installed (see `requirements.txt`) and `pytest.ini` addopts include `--cov`.
+- Import errors: activate the venv and reinstall requirements.
+- Plugin artifacts missing under `pytester`: verify tests write to `reports/` (our plugin creates the folder automatically in `pytest_configure`).

+# Power Supply (Owon) — control, configuration, tests, and quick demo
+
+This guide covers driving the Owon bench power supply via SCPI over a
+serial link, plus the cross-platform port resolver and the safety
+guarantees the controller class provides.
+
+> **MUM users**: the Melexis Universal Master has its own power output
+> on `power_out0` and the MUM adapter calls `power_up()` /
+> `power_down()` in `connect()` / `disconnect()` automatically. The
+> Owon PSU is **not required** for the standard MUM flow — leave
+> `power_supply.enabled: false`. The Owon remains useful for
+> over/under-voltage scenarios, separate-rail tests, or when running
+> with the deprecated BabyLIN adapter (which has no built-in power).
+
+| Artifact | Path |
+|---|---|
+| Controller library | [`ecu_framework/power/owon_psu.py`](../ecu_framework/power/owon_psu.py) |
+| Hardware test | [`tests/hardware/test_owon_psu.py`](../tests/hardware/test_owon_psu.py) |
+| Quick demo script | [`vendor/Owon/owon_psu_quick_demo.py`](../vendor/Owon/owon_psu_quick_demo.py) |
+| Central config | [`config/test_config.yaml`](../config/test_config.yaml) → `power_supply` |
+| Per-machine override | `config/owon_psu.yaml` or env `OWON_PSU_CONFIG` |
+
+---
+
+## 1. Install dependencies
+
+```powershell
+pip install -r .\requirements.txt
+```
+
+`pyserial` is the only non-stdlib dep used by the controller.
+
+---
+
+## 2. Configure
+
+Settings can live centrally in `config/test_config.yaml` or be peeled
+out into a machine-specific `config/owon_psu.yaml` (or any path set
+via `OWON_PSU_CONFIG`). The loader merges the per-machine file into
+the central `power_supply` section.
+
+```yaml
+power_supply:
+  enabled: true
+  port: COM7           # see §3 for cross-platform behaviour
+  baudrate: 115200
+  timeout: 1.0
+  eol: "\n"          # or "\r\n" if your device requires CRLF
+  parity: N            # N|E|O
+  stopbits: 1          # 1|1.5|2
+  xonxoff: false
+  rtscts: false
+  dsrdtr: false
+  idn_substr: OWON     # optional — see §4 (auto-detection)
+  do_set: false
+  set_voltage: 5.0
+  set_current: 0.1
+```
+
+### Field reference
+
+| Field | Default | Meaning |
+|---|---|---|
+| `enabled` | `false` | Master gate. Tests/utilities skip when `false`. |
+| `port` | `null` | Bench port name. See §3 — works for `COM7` *or* `/dev/ttyUSB0` and translates between them. |
+| `baudrate` | `115200` | Serial bit rate. |
+| `timeout` | `1.0` | Read timeout in seconds. |
+| `eol` | `"\n"` | Line terminator appended to every command and expected on every response. |
+| `parity` | `"N"` | One of `N`, `E`, `O`. Translated to `pyserial` constants by `SerialParams.from_config()`. |
+| `stopbits` | `1` | One of `1`, `1.5`, `2`. |
+| `xonxoff` / `rtscts` / `dsrdtr` | `false` | Flow control flags. |
+| `idn_substr` | `null` | Optional substring (case-insensitive) the device's `*IDN?` must contain to be accepted. Used as the filter when scanning ports for auto-detection. |
+| `do_set` | `false` | If `true`, the hardware test runs the set/measure cycle (sets V/I, enables output briefly, measures, disables). |
+| `set_voltage` / `set_current` | `5.0` / `0.1` | Setpoints used when `do_set: true`. |
+
+---
+
+## 3. Cross-platform port resolution
+
+A bench config typically names the port the way Windows sees it
+(`COM7`). The resolver lets the **same config** work on Windows,
+Linux, and WSL by trying multiple candidates in priority order.
+
+### What the resolver does
+
+`resolve_port(configured, *, idn_substr, params)` walks four phases
+and returns the first port whose `*IDN?` response is non-empty
+(filtered by `idn_substr` if given):
+
+| Phase | What's tried | Use case |
+|---|---|---|
+| 1 | `configured` verbatim | Windows native — `COM7` opens directly. |
+| 2 | Cross-platform translation | `COM7` ↔ `/dev/ttyS6` on WSL1; `/dev/ttyS6` ↔ `COM7` on Windows. |
+| 3 | Linux USB-serial paths | `/dev/ttyUSB*` and `/dev/ttyACM*` — covers WSL2 with `usbipd-win` plus generic Linux USB adapters. Linux/WSL only. |
+| 4 | Full `scan_ports()` | Last resort — probes every serial port `pyserial` reports. |
+
+Linux device files that don't exist on disk are skipped without an
+open attempt, so the resolver is fast even on machines with many
+phantom `ttyS*` entries.
+
+### What works on each platform with `port: COM7`
+
+| Host | What happens |
+|---|---|
+| **Windows native** | Phase 1 hits `COM7` directly. |
+| **WSL1** | Phase 1 fails on `COM7`, Phase 2 finds `/dev/ttyS6` (the COM7 mapping). |
+| **WSL2 + `usbipd-win`** | Phase 1+2 fail, Phase 3 finds the attached adapter at `/dev/ttyUSB0`. |
+| **Linux native (USB adapter)** | Phases 1+2 fail, Phase 3 finds `/dev/ttyUSB0`. |
+
+The resolved port is recorded in the JUnit testsuite properties as
+`psu_resolved_port` (and the IDN as `psu_resolved_idn`), so report
+viewers can see which path was used.
+
+### Translation helpers
+
+Useful as building blocks if you need to do the mapping yourself:
+
+```python
+from ecu_framework.power import (
+    windows_com_to_linux, linux_serial_to_windows,
+    candidate_ports, resolve_port,
+)
+
+windows_com_to_linux("COM7")          # → "/dev/ttyS6"
+windows_com_to_linux("com10")         # → "/dev/ttyS9"
+linux_serial_to_windows("/dev/ttyS6") # → "COM7"
+
+# What resolve_port will try, in order, for port="COM7" on Linux:
+candidate_ports("COM7")
+# → ['COM7', '/dev/ttyS6', '/dev/ttyUSB0', '/dev/ttyUSB1', '/dev/ttyACM0', ...]
+```
+
+---
+
+## 4. Auto-detection
+
+Leave `port` empty and set `idn_substr` to let the resolver scan:
+
+```yaml
+power_supply:
+  enabled: true
+  port:                # ← empty
+  idn_substr: OWON     # ← required so we don't grab a different SCPI device
+  ...
+```
+
+With no `port`, Phase 1 and Phase 2 short-circuit; Phase 3 (Linux USB
+paths) and Phase 4 (full scan) do the work. The first port whose IDN
+contains `OWON` (case-insensitive) wins.
+
+> **Tip:** without `idn_substr`, *any* device that responds to `*IDN?`
+> on any port is accepted — fine when the PSU is the only SCPI thing
+> attached, risky otherwise. Always set `idn_substr` if your bench has
+> other SCPI hardware.
+
+---
+
+## 5. Session-managed power (the bench powers the ECU through the PSU)
+
+On benches where the **Owon PSU powers the ECU** (the MUM only carries
+LIN traffic), the PSU output must stay on for the *entire* test
+session — not just the duration of an individual PSU test. Otherwise
+every test that runs after a closed PSU connection would brown out
+the ECU and fail.
+
+The hardware-suite conftest
+([`tests/hardware/conftest.py`](../tests/hardware/conftest.py))
+implements this with three session-scoped fixtures:
+
+| Fixture | Scope | Role |
+|---|---|---|
+| `_psu_or_none` | session | Tolerant: opens the PSU once, parks at `set_voltage` / `set_current`, enables output. Yields the live `OwonPSU` or `None` if unreachable. Closes (with `output 0`) at session end. |
+| `_psu_powers_bench` | session, **autouse** | Realizes `_psu_or_none`. Every hardware test triggers PSU power-up at session start, even tests that don't request `psu` by name. |
+| `psu` | session | Public fixture for tests that read measurements or perturb voltage. Skips cleanly when the PSU isn't available. |
+
+### What this means for tests
+
+Tests **should**:
+
+- Request `psu` if they need to read measurements or change the supply voltage.
+- Always restore nominal voltage in their `finally` block — the session fixture won't restore it between tests.
+
+Tests **must not**:
+
+- Call `psu.set_output(False)` — this kills ECU power for every later test in the same session.
+- Call `psu.close()` — the session fixture owns the lifecycle.
+
+### What changed in the existing tests
+
+- **`tests/hardware/test_owon_psu.py`** is now read-only: it queries `*IDN?`, `output?`, and the parsed measurement helpers, but doesn't toggle the output. The previous toggle-and-restore cycle has been deleted because it would brown out the bench mid-session.
+- **`tests/hardware/_test_case_template_psu_lin.py`** drops its local `psu` fixture and uses the conftest's. Its autouse `_park_at_nominal` only restores voltage between tests — it never toggles output.
+
+---
+
+## 6. Run the hardware test
+
+Skips cleanly unless `power_supply.enabled` is true, a port can be
+resolved, and the device responds to `*IDN?`.
+
+```powershell
+pytest -k test_owon_psu_idn_and_optional_set -m hardware -q
+```
+
+What it does:
+
+1. Resolves a working port via `resolve_port(...)` (cross-platform,
+   IDN-verified).
+2. Queries `*IDN?` and the initial `output?` state.
+3. If `do_set` is true: sets V/I, enables output, waits, measures,
+   disables output. The measure/disable pair lives in an inner
+   `try`/`finally` so the disable runs even if measurement raises.
+4. Records IDN, before/after output state, setpoints, and parsed
+   measurements as report properties.
+5. The fixture's `safe_off_on_close=True` is a backstop — it will
+   send `output 0` once more when the port closes.
+
+The test follows the four-phase
+[SETUP / PROCEDURE / ASSERT / TEARDOWN pattern from the template](19_frame_io_and_alm_helpers.md#72-the-four-phase-test-pattern)
+because it mutates real bench state.
+
+### The settle-then-validate pattern (recommended for any voltage-changing test)
+
+Voltage changes go through two delays — and confusing them is the
+single most common source of flaky tests:
+
+| Delay | Source | Bench-dependent? |
+|---|---|---|
+| **PSU settling** | Owon needs time to slew its output to the new setpoint | **Yes** — depends on PSU model, load, cable drop. Different up-step / down-step times in practice. |
+| **ECU validation** | Firmware samples its supply rail, debounces, and republishes status on its 10 ms LIN cycle | No (firmware-dependent, but constant for a given build) |
+
+The shared helper [`tests/hardware/psu_helpers.py`](../tests/hardware/psu_helpers.py)
+exposes `apply_voltage_and_settle()` which separates the two cleanly:
+
+```python
+from psu_helpers import apply_voltage_and_settle
+
+result = apply_voltage_and_settle(
+    psu, OVERVOLTAGE_V,
+    validation_time=ECU_VALIDATION_TIME_S,    # firmware budget
+)
+# By here:
+#   - PSU output is measurably at OVERVOLTAGE_V (within ±0.10 V)
+#   - validation_time has elapsed since the rail settled
+# So a single status read is unambiguous:
+status = fio.read_signal("ALM_Status", "ALMVoltageStatus")
+assert status == VOLTAGE_STATUS_OVER
+```
+
+What `apply_voltage_and_settle` does internally:
+
+1. `psu.set_voltage(1, target_v)` — issue the setpoint.
+2. Polls `measure_voltage_v()` every 50 ms until the rail is within
+   ±100 mV of target (or raises `AssertionError` on timeout).
+3. `time.sleep(validation_time)` — hold the steady rail.
+4. Returns `{settled_s, validation_s, final_v, trace}` for reporting.
+
+The poll-the-meter approach means the function works on any bench
+without re-tuning sleeps. Up-step and down-step are handled
+identically — each waits as long as that *specific* transition takes.
+
+To pick `ECU_VALIDATION_TIME_S`, run the characterization in §6.1
+to learn your PSU's slew time, then add a margin for the firmware's
+detection-and-debounce window. Default `1.0 s` is conservative for
+most automotive ECUs. Tests that change voltage many times should
+use the smallest validation time their firmware tolerates.
+
+### Characterizing PSU settling time
+
+Voltage-tolerance tests need to wait long enough after a setpoint
+change for the PSU's output to actually reach the new voltage. The
+right wait depends on the PSU model and the load. To extract real
+numbers, run the dedicated characterization test:
+
+```powershell
+pytest -m psu_settling -s
+```
+
+`tests/hardware/test_psu_voltage_settling.py` walks four
+transitions (`13 V↔18 V`, `13 V↔7 V`), polls `measure_voltage_v()`
+every 50 ms until the rail is within ±100 mV of target, and records
+`settling_time_s` plus a downsampled voltage trace per case. The
+test is marked `psu_settling` + `slow` so it doesn't run on every
+`-m hardware` invocation — it's meant for periodic re-tuning, not
+every CI run.
+
+Use the recorded settling times to size constants like
+`VOLTAGE_DETECT_TIMEOUT` in `test_overvolt.py`: the timeout has to
+exceed *both* the PSU's settling time *and* the ECU's detection
+delay, so add a margin to the larger of the two.
+
+### Writing a PSU+LIN test (over/undervoltage etc.)
+
+For tests that *combine* PSU control with LIN observation — e.g.
+overvoltage / undervoltage tolerance — there's a dedicated
+copy-paste-ready template at
+[`tests/hardware/_test_case_template_psu_lin.py`](../tests/hardware/_test_case_template_psu_lin.py).
+It contains:
+
+- The three module-scoped fixtures (`fio`, `alm`, `psu`) wired with
+  cross-platform port resolution and `safe_off_on_close=True`.
+- An autouse `_park_at_nominal` fixture that parks the PSU at
+  `NOMINAL_VOLTAGE` and the LED OFF before AND after every test, so
+  failures don't leak supply state between tests.
+- A `wait_for_voltage_status(fio, target, …)` helper that polls
+  `ALM_Status.ALMVoltageStatus` until it matches.
+- Three flavors:
+  | Flavor | Demonstrates |
+  |---|---|
+  | A | Overvoltage detection — drive PSU above OV threshold, expect `ALMVoltageStatus = 0x02`, restore. |
+  | B | Undervoltage detection — symmetric for UV (`0x01`). |
+  | C | Parametrized voltage sweep walking `(V, expected_status)` tuples. |
+
+Tune the four constants at the top of the file
+(`NOMINAL_VOLTAGE`, `OVERVOLTAGE_V`, `UNDERVOLTAGE_V`,
+`SET_CURRENT_A`) to your ECU's datasheet before running on real
+hardware. The defaults are conservative automotive ranges.
+
+---
+
+## 7. Library API
+
+```python
+from ecu_framework.power import (
+    SerialParams, OwonPSU, resolve_port,
+    scan_ports, auto_detect, try_idn_on_port,
+)
+```
+
+### `SerialParams`
+
+Plain dataclass for serial-port settings. Build directly, or from the
+project's PSU config:
+
+```python
+params = SerialParams(baudrate=115200, timeout=1.0)
+# or
+params = SerialParams.from_config(config.power_supply)   # translates 'N'/'1' → pyserial constants
+```
+
+### `OwonPSU`
+
+Context-managed controller. Two construction paths:
+
+```python
+# Manual:
+psu = OwonPSU(port="COM4", params=params, eol="\n")
+
+# From central config (recommended):
+psu = OwonPSU.from_config(config.power_supply)
+```
+
+Then either use as a context manager or call `open()` / `close()` by
+hand. Both forms send `output 0` before closing the port if
+`safe_off_on_close=True` (the default).
+
+```python
+with OwonPSU.from_config(cfg) as psu:
+    print(psu.idn())                      # *IDN?
+    psu.set_voltage(1, 5.0)               # SOUR:VOLT 5.000
+    psu.set_current(1, 0.1)               # SOUR:CURR 0.100
+    psu.set_output(True)                  # output 1
+    v = psu.measure_voltage_v()           # MEAS:VOLT? → float
+    i = psu.measure_current_a()           # MEAS:CURR? → float
+    is_on = psu.output_is_on()            # output? → True/False/None
+# safe_off_on_close=True turned the output OFF before the port closed
+```
+
+#### Method reference
+
+| Method | SCPI sent | Returns |
+|---|---|---|
+| `idn()` | `*IDN?` | `str` |
+| `set_voltage(channel, volts)` | `SOUR:VOLT <V>` | `None`. `channel` is currently ignored — placeholder for multi-channel firmware. |
+| `set_current(channel, amps)` | `SOUR:CURR <A>` | `None` |
+| `set_output(on)` | `output 1`/`output 0` | `None`. Note: dialect uses *lowercase* `output`, not `OUTP ON`. |
+| `output_status()` | `output?` | Raw `str` (`'ON'`/`'OFF'`/`'1'`/`'0'`). |
+| `output_is_on()` | `output?` | `bool` (or `None` if unparseable). |
+| `measure_voltage()` | `MEAS:VOLT?` | Raw `str`. |
+| `measure_voltage_v()` | `MEAS:VOLT?` | `float` (V) or `None`. |
+| `measure_current()` | `MEAS:CURR?` | Raw `str`. |
+| `measure_current_a()` | `MEAS:CURR?` | `float` (A) or `None`. |
+| `query(s)` | `s` | Single-line `str` response (with newline stripped). |
+| `write(s)` | `s` | `None`. No response read. |
+
+#### Safety: `safe_off_on_close`
+
+`OwonPSU(safe_off_on_close=True)` (the default) sends `output 0`
+before the serial port closes. This protects against leaving the
+bench powered on after an aborted test, an exception in user code, or
+a forgotten manual close. Errors during the safe-off attempt are
+swallowed so the close itself always completes.
+
+Pass `safe_off_on_close=False` only when you specifically need the
+output to stay enabled across context-manager boundaries. The
+discovery helper `try_idn_on_port` opts out by default since it
+shouldn't drive the bench in either direction.
+
+### Discovery helpers
+
+```python
+# Probe one port, return its IDN (or "" on failure):
+try_idn_on_port("COM7", params)
+
+# Scan every serial port; returns [(port, idn), ...] for responders:
+scan_ports(params)
+
+# Pick the first responder matching idn_substr (or first responder if no substring):
+auto_detect(params, idn_substr="OWON")
+
+# Cross-platform resolver (recommended): tries the configured port,
+# its translation, USB-serial paths, then a full scan. Returns
+# (port, idn) or None.
+resolve_port("COM7", idn_substr="OWON", params=params)
+```
+
+---
+
+## 8. Quick demo script
+
+The quick demo reads `OWON_PSU_CONFIG` or `config/owon_psu.yaml` and
+performs a short sequence using the same library.
+
+```powershell
+python .\vendor\Owon\owon_psu_quick_demo.py
+```
+
+It also scans ports with `*IDN?` via `scan_ports()` to help confirm
+which port the device is on before you commit it to the YAML.
+
+---
+
+## 9. Troubleshooting
+
+### Empty `*IDN?` / timeouts
+
+- Verify the port and exclusivity — no other program may hold it open.
+- Try `eol: "\r\n"` if your firmware revision expects CRLF.
+- Adjust `parity` and `stopbits` per your device manual.
+- Power-cycle the PSU and re-attempt — some firmware revisions need
+  a fresh boot before they accept SCPI.
+
+### `Could not find a working PSU port`
+
+The fixture skips with this message when `resolve_port` returns
+`None`. Things to check, in order:
+
+1. Is the device powered and connected?
+2. Does another process (Putty, Owon's own tool, an old test session)
+   still hold the port?
+3. Does your user have permission to open the device file? On
+   Debian-style systems: `sudo usermod -aG dialout $USER` and re-login.
+4. **WSL2 specifically**: USB-serial adapters need
+   [`usbipd-win`](https://learn.microsoft.com/en-us/windows/wsl/connect-usb)
+   to bind the device into the Linux side. Once attached they appear
+   at `/dev/ttyUSB0` and the resolver's Phase 3 picks them up
+   automatically.
+5. **WSL1**: COMx → /dev/ttySn mapping is automatic. If `/dev/ttyS6`
+   doesn't exist for `COM7`, the bench probably has Windows COM port
+   numbering you weren't expecting — list with
+   `ls /dev/ttyS*` and try `linux_serial_to_windows()` to confirm.
+
+### Windows COM > 9
+
+Most Python tooling (including `pyserial`) accepts `COM10` directly.
+If a third-party tool needs the long form, use `\\.\COM10`. The
+translator in this repo accepts any positive integer.
+
+### Flow control
+
+Keep `xonxoff`, `rtscts`, `dsrdtr` set to `false` unless your specific
+PSU model requires otherwise — the Owon family used in this project
+doesn't.

+# MUM Adapter Internals (Melexis Universal Master)
+
+This document describes how the `MumLinInterface` adapter wraps the Melexis
+`pymumclient` and `pylin` packages, how frames flow across the LIN bus, and
+which MUM-specific behaviors callers need to understand.
+
+## Overview
+
+- Location: `ecu_framework/lin/mum.py`
+- Vendor reference scripts: `vendor/automated_lin_test/` (`test_led_control.py`, `test_auto_addressing.py`, `power_cycle.py`)
+- Default MUM endpoint: `192.168.7.2` over USB-RNDIS
+- LIN device name on MUM: `lin0`
+- Power-control device on MUM: `power_out0`
+- Required Python packages: `pylin`, `pymumclient` (Melexis-supplied; not on PyPI). See `vendor/automated_lin_test/install_packages.sh`.
+
+## What the MUM gives you that BabyLIN doesn't
+
+- **Built-in power control** on `power_out0` — the adapter calls `power_up()` in `connect()` and `power_down()` in `disconnect()`. No external Owon PSU needed for the standard flow.
+- **Network access**: the MUM is IP-reachable, so the host machine (Windows, Linux, Pi) does not need vendor native libraries — only the two Python packages.
+- **Direct transport-layer access** for sending raw frames with LIN 1.x **Classic** checksum (required for BSM-SNPD diagnostic frames).
+
+## What it doesn't give you
+
+- **No passive listen.** The MUM is master-driven. To "receive" a slave-published frame, the master sends a header on that frame ID and the slave must respond. `MumLinInterface.receive(id=None)` raises `NotImplementedError` for that reason.
+- **No SDF / schedule manager.** The adapter does not run a schedule; tests publish frames explicitly (or pull slave frames explicitly) on each call.

+## Public API
+
+`MumLinInterface(host, lin_device='lin0', power_device='power_out0', baudrate=19200, frame_lengths=None, default_data_length=8, boot_settle_seconds=0.5)`
+
+LinInterface contract (matches Mock and BabyLIN adapters):
+
+- `connect()` — opens MUM, sets up LIN, **and powers up the ECU**
+- `disconnect()` — powers down and tears down (best-effort)
+- `send(frame: LinFrame)` — publishes a master-to-slave frame using Enhanced checksum
+- `receive(id: int, timeout: float = 1.0) -> LinFrame | None` — triggers a slave read for `id`. The `timeout` argument is informational; the underlying `pylin` call is synchronous. Any pylin exception is treated as "no data" and returns `None`. Passing `id=None` raises `NotImplementedError`.
+
+MUM-only extras:
+
+- `send_raw(bytes)` — sends a raw LIN frame using **Classic** checksum via the transport layer's `ld_put_raw`. Use this for BSM-SNPD diagnostic frames; the firmware will reject them if Enhanced is used.
+- `power_up()` / `power_down()` — direct control over `power_out0`
+- `power_cycle(wait=2.0)` — convenience: `power_down()`, sleep, `power_up()`, then `boot_settle_seconds` sleep
+
+## Frame-length resolution
+
+Because the MUM is master-driven, every receive needs to know how many bytes
+to ask for. The adapter resolves this from `frame_lengths`:
+
+1. Built-in defaults for the 4SEVEN library (ALM_Status=4, ALM_Req_A=8, ConfigFrame=3, PWM_Frame=8, VF_Frame=8, Tj_Frame=8, PWM_wo_Comp=8, NVM_Debug=8).
+2. Anything in the constructor's `frame_lengths` argument **overrides** the defaults.
+3. If a frame ID isn't in the map, `default_data_length` (default 8) is used.
+
+In YAML, hex keys work:
+
+```yaml
+interface:
+  type: mum
+  frame_lengths:
+    0x0A: 8
+    0x11: 4
+```
+
+The config loader coerces hex strings (`"0x0A"`) and integers alike.
+
+## Diagnostic frames (BSM-SNPD)
+
+The vendor's `test_auto_addressing.py` flow runs LIN 2.1 BSM-SNPD via raw
+frames on `0x3C` (MasterReq). The framework supports the same flow:
+
+```python
+# inside a test that already has the MUM 'lin' fixture
+data = bytearray([
+    0x7F,  # NAD broadcast
+    0x06,  # PCI: 6 data bytes
+    0xB5,  # SID: BSM-SNPD
+    0xFF,  # Supplier ID LSB
+    0x7F,  # Supplier ID MSB
+    0x01,  # subfunction (INIT)
+    0x02,  # param 1
+    0xFF,  # param 2
+])
+lin.send_raw(bytes(data))
+```
+
+`send_raw()` calls `transport_layer.ld_put_raw(data=..., baudrate=...)`
+which uses LIN 1.x Classic checksum. Using `lin.send()` for these frames
+would compute Enhanced checksum and the firmware would discard the frame.
+
+## Error surfaces
+
+- **`pymumclient is not installed`** / **`pylin is not installed`** — raised on `connect()` if the Melexis packages aren't importable. The error message points at `vendor/automated_lin_test/install_packages.sh`.
+- **`MUM not connected`** — calling `send` / `receive` / `send_raw` before `connect()` (or after `disconnect()`).
+- **`MUM transport layer not available`** — raised by `send_raw` when the LIN device didn't expose `bus/transport_layer`. Practically always available on MUM firmware that supports diagnostic frames.
+- **pylin exceptions during `receive`** — converted to `None` (treated as a timeout / no-data). Use this to drive timeout-tolerant tests without try/except in the test body.
+
+## Unit testing without hardware
+
+The adapter accepts `mum_module=` and `pylin_module=` constructor arguments
+that bypass the real package imports. Tests in
+`tests/unit/test_mum_adapter_mocked.py` use simple in-memory fakes to drive
+the connect / send / receive / send_raw / power-cycle paths end to end. See
+that file for a complete shim implementation.
+
+```python
+from ecu_framework.lin.mum import MumLinInterface
+
+iface = MumLinInterface(
+    host="10.0.0.1",
+    boot_settle_seconds=0.0,
+    mum_module=fake_mum,
+    pylin_module=fake_pylin,
+)
+iface.connect()
+# ... assertions ...
+iface.disconnect()
+```
+
+## Notes and pitfalls
+
+- **Boot settling**: After `power_up()` the adapter sleeps `boot_settle_seconds` (default 0.5 s) so the ECU has time to come up before the first frame. Increase if your ECU boots slowly.
+- **Owon PSU coexistence**: the MUM provides power on `power_out0` independently of `ecu_framework/power/`. Leave `power_supply.enabled: false` for the standard MUM flow; enable it only for over/under-voltage scenarios that need a separate, programmable rail.
+- **Networking**: USB-RNDIS bring-up can take a few seconds after plugging in the MUM. If `connect()` fails with a connection-refused, `ping 192.168.7.2` first.
+- **Multiple MUMs**: only one MUM is supported per `MumLinInterface` instance. Different `host` addresses can run different fixture sessions side-by-side.

+# LDF Parser & Frame Helpers
+
+The framework parses your LDF (LIN Description File) at session start and
+exposes a typed `LdfDatabase` to tests. Tests then build and decode frames
+by **signal name**, never by hand-counting bit positions.
+
+## Why
+
+Hard-coded frame layouts (the `ALM_REQ_A_FRAME = {...}` style in
+`vendor/automated_lin_test/config.py`) drift the moment the LDF changes.
+Loading the LDF directly removes the drift and gives you a pleasant API:
+
+```python

+    payload = req.pack(
+        AmbLightColourRed=0xFF, AmbLightColourGreen=0xFF,
+        AmbLightColourBlue=0xFF, AmbLightIntensity=0xFF,

+    sig = ldf.frame("ALM_Status").unpack(bytes(raw.data))
+    assert sig["ALMNadNo"] == nad
+```
+
+## Where it lives
+
+- Parser wrapper: `ecu_framework/lin/ldf.py`
+- Test fixture: `ldf` (session-scoped, in `tests/conftest.py`)
+- Underlying library: [`ldfparser`](https://pypi.org/project/ldfparser/) (pure-Python, MIT)
+- LDF location is read from `interface.ldf_path` in YAML
+- Unit tests against `vendor/4SEVEN_color_lib_test.ldf`: `tests/unit/test_ldf_database.py`
+
+## Configuration
+
+Set `interface.ldf_path` (relative paths resolve against the workspace root):
+
+```yaml
+interface:
+  type: mum
+  host: 192.168.7.2
+  bitrate: 19200
+  ldf_path: ./vendor/4SEVEN_color_lib_test.ldf
+  # frame_lengths is optional: any keys here override the LDF on a
+  # per-frame-id basis. Leave empty to inherit everything from the LDF.
+  frame_lengths: {}
+```
+
+When `ldf_path` is set, the `lin` fixture also feeds the LDF's
+`{frame_id: length}` map into `MumLinInterface(frame_lengths=...)`, so
+`lin.receive(id=...)` knows the right number of bytes to ask for **for
+every frame in the LDF** — no per-id bookkeeping required.
+
+## API
+
+### `LdfDatabase`
+
+```python
+from ecu_framework.lin.ldf import LdfDatabase
+
+db = LdfDatabase("./vendor/4SEVEN_color_lib_test.ldf")
+
+db.protocol_version    # "2.1"
+db.baudrate            # 19200
+
+db.frame("ALM_Req_A")   # by name
+db.frame(0x0A)          # by frame_id
+db.frames()             # list[Frame]
+
+db.frame_lengths()      # {frame_id: length} — drop into MumLinInterface
+db.signal_names("ALM_Req_A")   # ['AmbLightColourRed', ...]
+```
+
+`db.frame(...)` raises `FrameNotFound` (a `KeyError` subclass) if the name
+or ID isn't present; missing files raise `FileNotFoundError`.
+
+### `Frame`
+
+```python
+frame = db.frame("ALM_Req_A")
+
+frame.id          # 0x0A (int)
+frame.name        # "ALM_Req_A"
+frame.length      # 8
+
+frame.signal_names()      # ['AmbLightColourRed', ...]
+frame.signal_layout()     # [(start_bit, name, width), ...]
+
+# Raw integer pack/unpack — use this for tests that work in raw values.
+payload = frame.pack(AmbLightColourRed=255, AmbLightColourGreen=128)
+payload = frame.pack({"AmbLightColourRed": 255})  # dict form is fine too
+
+decoded = frame.unpack(payload)   # {'AmbLightColourRed': 255, ...}
+
+# Encoding-aware variant (logical/physical values from the LDF) — use this
+# if you want to write `AmbLightUpdate="Immediate color Update"`:
+encoded = frame.encode({"AmbLightUpdate": "Immediate color Update", ...})
+decoded = frame.decode(encoded)
+```
+
+### Default values
+
+`pack()` doesn't require every signal — anything you omit takes the
+**`init_value` declared in the LDF**. For example, `ColorConfigFrameRed`'s
+`_X` signal has `init_value = 5665`, so `frame.pack()` with no kwargs
+produces a payload that decodes back to that value:
+
+```python
+db.frame("ColorConfigFrameRed").unpack(db.frame("ColorConfigFrameRed").pack())
+# → {'ColorConfigFrameRed_X': 5665, 'ColorConfigFrameRed_Y': 2396, ...}
+```
+
+This means you can usually pass only the signals the test cares about and
+let the LDF supply sensible defaults for the rest.
+
+## The `ldf` fixture
+
+`tests/conftest.py` provides a session-scoped `ldf` fixture that:
+
+1. Reads `interface.ldf_path` from config.
+2. Resolves it against the workspace root if relative.
+3. Skips the test cleanly with a clear message if the path is missing,
+   the file isn't there, or `ldfparser` isn't installed.
+4. Returns an `LdfDatabase`.
+
+A test that needs LDF-defined frames simply requests it:
+
+```python
+def test_thing(lin, ldf):
+    payload = ldf.frame("ALM_Req_A").pack(AmbLightColourRed=0xFF)
+    lin.send(LinFrame(id=ldf.frame("ALM_Req_A").id, data=payload))
+```
+
+Tests that don't need LDF can ignore the fixture; nothing is loaded
+unless the fixture is requested.
+
+## Switching between raw and encoded values
+
+| Use this | When |
+| --- | --- |
+| `frame.pack(**raw_ints) / frame.unpack(bytes)` | You're writing test logic against numeric signal values (most assertions). |
+| `frame.encode(values_dict) / frame.decode(bytes)` | You want LDF logical names (`"Immediate color Update"`) or scaled physical values (e.g. `AmbLightDuration` is `value × 0.2 s`). |
+
+Both round-trip through the same byte representation; the difference is
+purely how the values look in Python.
+
+## Common pitfalls
+
+- **Frame ID ranges**: `LinFrame` validates IDs as 0x00..0x3F (LIN classic 6-bit). `ldfparser` returns IDs in this range for normal frames; diagnostic frames (`MasterReq=0x3C`, `SlaveResp=0x3D`) are also accepted. If you ever see an out-of-range ID, you're probably looking at an event-triggered frame's collision resolution table — not a real bus ID.
+- **Bit ordering**: LDF and ldfparser both use the LIN-standard little-endian bit ordering within bytes. The framework's `Frame.pack()` matches the existing hand-rolled `vendor/automated_lin_test/config.py:pack_frame()` byte-for-byte for the 4SEVEN file.
+- **`encode` vs `encode_raw`**: ldfparser's `encode()` insists on encoded values (`"Immediate color Update"` not `0`). Our `Frame.pack()` uses `encode_raw()` instead, so kwargs are integers. If you need encoded names, use `Frame.encode(dict)` explicitly.
+
+## Migration from hardcoded frames
+
+If you have tests that import the dicts in `vendor/automated_lin_test/config.py`
+(`ALM_REQ_A_FRAME`, etc.) and call its `pack_frame` / `unpack_frame`, they
+keep working — the new system is additive. To migrate a test:
+
+```python
+# Before
+from config import ALM_REQ_A_FRAME, pack_frame
+data = pack_frame(ALM_REQ_A_FRAME, AmbLightColourRed=255, ...)
+lin.send_message(master_to_slave=True, frame_id=ALM_REQ_A_FRAME['frame_id'],
+                 data_length=ALM_REQ_A_FRAME['length'], data=data)
+
+# After
+def test(lin, ldf):
+    f = ldf.frame("ALM_Req_A")
+    lin.send(LinFrame(id=f.id, data=f.pack(AmbLightColourRed=255, ...)))
+```

+Pure-Python tests that don't touch hardware or external I/O. Run on every PR.
+
+### 1.1 `test_linframe.py` — `LinFrame` validation
+
+Source: [tests/unit/test_linframe.py](tests/unit/test_linframe.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_linframe_accepts_valid_ranges` | `unit` | Construct a `LinFrame(id=0x3F, data=8 bytes of zero)` and assert id/length round-trip cleanly. Ensures the maximum legal LIN classic ID and 8-byte payload are accepted. |
+| `test_linframe_invalid_id_raises[-1]` / `[64]` | `unit` | Parametrized: `LinFrame(id=-1)` and `LinFrame(id=0x40)` must raise `ValueError`. Confirms the 0x00–0x3F clamp on classic LIN IDs. |
+| `test_linframe_too_long_raises` | `unit` | `LinFrame(id=0x01, data=9 bytes)` must raise `ValueError`. Confirms the 8-byte payload upper bound. |
+
+**Why it matters:** `LinFrame` is the type every adapter (Mock/MUM/BabyLIN) hands back to tests. If validation drifts, all downstream tests get more permissive silently.
+
+---
+
+### 1.2 `test_config_loader.py` — YAML configuration precedence
+
+Source: [tests/unit/test_config_loader.py](tests/unit/test_config_loader.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_config_precedence_env_overrides` | `unit` | Writes a temp YAML with `interface.type: babylin` / `channel: 7`, points `ECU_TESTS_CONFIG` at it, then loads with `overrides={"interface": {"channel": 9}}`. Asserts the YAML's `type` made it through and the in-code override beat the YAML's `channel`. |
+| `test_config_defaults_when_no_file` | `unit` | With no `ECU_TESTS_CONFIG` and no workspace root, `load_config()` must return defaults (`type: mock`, `flash.enabled: false`). |
+
+**Precedence order asserted:** in-code `overrides` > `ECU_TESTS_CONFIG` env > `config/test_config.yaml` > built-in defaults.

+
+### 1.3 `test_babylin_adapter_mocked.py` — BabyLIN adapter error path
+
+Source: [tests/unit/test_babylin_adapter_mocked.py](tests/unit/test_babylin_adapter_mocked.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_connect_sdf_error_raises` | `unit` | Inject a fake BabyLIN wrapper whose `BLC_loadSDF` returns a non-OK code. `BabyLinInterface.connect()` must raise `RuntimeError`. Validates that SDK error codes during SDF download surface as Python exceptions instead of being silently ignored. |
+
+---
+
+### 1.4 `test_mum_adapter_mocked.py` — MUM adapter plumbing
+
+Source: [tests/unit/test_mum_adapter_mocked.py](tests/unit/test_mum_adapter_mocked.py)
+
+All cases inject fake `pymumclient` and `pylin` modules so the adapter can be exercised with no MUM hardware.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_connect_opens_mum_and_powers_up` | `unit` | `connect()` calls `MelexisUniversalMaster.open_all(host)`, `linmaster.setup()`, sets `lin_dev.baudrate`, and powers up the ECU exactly once. |
+| `test_disconnect_powers_down_and_tears_down` | `unit` | `disconnect()` calls `power_control.power_down()` and `linmaster.teardown()` exactly once each. |
+| `test_send_publishes_master_frame` | `unit` | `lin.send(LinFrame(0x0A, 8 bytes))` calls `lin_dev.send_message(master_to_slave=True, frame_id=0x0A, data_length=8, data=[...])`. |
+| `test_receive_uses_frame_lengths_default` | `unit` | `lin.receive(id=0x11)` reads the configured length (4) from the default `frame_lengths` map and returns the slave bytes wrapped in a `LinFrame`. |
+| `test_receive_returns_none_on_pylin_exception` | `unit` | If pylin raises during `send_message(master_to_slave=False, ...)`, `receive()` must return `None` (treated as timeout). Stops tests from having to wrap every receive in try/except. |
+| `test_receive_without_id_raises` | `unit` | `lin.receive(id=None)` must raise `NotImplementedError`. The MUM is master-driven; passive listen is unsupported. |
+| `test_send_raw_uses_classic_checksum_path` | `unit` | `lin.send_raw(bytes)` calls `transport_layer.ld_put_raw(data, baudrate=19200)`. This is the path BSM-SNPD diagnostic frames need (Classic checksum). |
+| `test_power_cycle_calls_down_then_up` | `unit` | `lin.power_cycle(wait=0)` issues at least one extra `power_down()` and the matching `power_up()` on top of the connect-time power up. |
+

+
+### 1.5 `test_ldf_database.py` — LDF parser wrapper
+
+Source: [tests/unit/test_ldf_database.py](tests/unit/test_ldf_database.py)
+
+Module is skipped automatically if `ldfparser` isn't installed. Uses `vendor/4SEVEN_color_lib_test.ldf` as fixture data.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_loads_metadata` | `unit` | `db.protocol_version` is one of `1.3`/`2.0`/`2.1` and `db.baudrate == 19200` for the 4SEVEN LDF. |
+| `test_lookup_by_name_and_id` | `unit` | `db.frame("ALM_Req_A")` and `db.frame(0x0A)` return the same frame; id/name/length match the LDF Frames block. |
+| `test_unknown_frame_raises` | `unit` | `db.frame("not_a_real_frame")` raises `FrameNotFound`. |
+| `test_signal_layout_matches_ldf` | `unit` | `frame.signal_layout()` for `ALM_Req_A` contains the exact `(start_bit, name, width)` tuples from the LDF (spot-checks `AmbLightColourRed`, `AmbLightUpdate`, `AmbLightMode`, `AmbLightLIDTo`). |
+| `test_pack_kwargs_full_payload` | `unit` | `frame.pack(...)` with all signals provided produces an 8-byte payload `ffffffff00000101`. |
+| `test_pack_unspecified_signals_use_init_value` | `unit` | `frame.pack()` with no kwargs uses each signal's LDF `init_value`. Verified by decoding the packed output for `ColorConfigFrameRed` (which has non-zero init values like 5665). |
+| `test_pack_dict_argument` | `unit` | `frame.pack({...})` and `frame.pack(**{...})` produce identical bytes. |
+| `test_pack_rejects_args_and_kwargs_together` | `unit` | `frame.pack({"X": 1}, Y=2)` raises `TypeError`. |
+| `test_unpack_round_trip` | `unit` | A non-trivial value set (RGB, intensity, mode bits, LID range) packs and unpacks back to the same dict. |
+| `test_alm_status_decode_real_payload` | `unit` | `unpack(b"\\x07\\x00\\x00\\x00")` on `ALM_Status` yields `ALMNadNo == 7`. |
+| `test_frame_lengths_includes_all_unconditional_frames` | `unit` | `db.frame_lengths()` contains every unconditional frame ID with a positive length (sanity: ALM_Req_A=8, ALM_Status=4, ConfigFrame=3). |
+| `test_frames_returns_wrapped_frame_objects` | `unit` | `db.frames()` returns wrapped `Frame` objects whose names cover the expected set (ALM_Req_A, ALM_Status, ConfigFrame…). |
+| `test_ldf_repr_does_not_explode` | `unit` | `repr(db)` includes `LdfDatabase` and doesn't raise. |
+| `test_missing_file_raises_filenotfounderror` | `unit` | `LdfDatabase(missing_path)` raises `FileNotFoundError`. |
+

+
+### 1.6 `test_hex_flasher.py` — flashing scaffold
+
+Source: [tests/unit/test_hex_flasher.py](tests/unit/test_hex_flasher.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_hex_flasher_sends_basic_sequence` | `unit` | Writes a minimal Intel HEX (EOF-only) and runs `HexFlasher(stub_lin).flash_hex(path)`. Asserts no exception and that `lin.sent` is a list. Placeholder until the flasher is fleshed out with UDS — once real UDS is wired in, this test gains real assertions about the byte sequence. |
+
+---
+
+## 2. Mock-loopback smoke — `tests/`
+
+Tests that exercise the full LinInterface API (send / receive / request) using either the in-process Mock adapter or the BabyLIN adapter with a mock SDK wrapper.
+
+### 2.1 `test_smoke_mock.py` — Mock adapter end-to-end
+
+Source: [tests/test_smoke_mock.py](tests/test_smoke_mock.py)
+
+Module-local `lin` fixture forces `MockBabyLinInterface` regardless of the central config, so these always run as mock-only tests.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `TestMockLinInterface::test_mock_send_receive_echo` | `smoke req_001 req_003` | Send `LinFrame(0x12, [1,2,3])` and receive it back through the mock's loopback. ID and data must match exactly. |
+| `TestMockLinInterface::test_mock_request_synthesized_response` | `smoke req_002` | `lin.request(id=0x21, length=4)` returns a deterministic frame where `data[i] == (id + i) & 0xFF`. The mock implements this pattern so request/response logic can be tested without hardware. |
+| `TestMockLinInterface::test_mock_receive_timeout_behavior` | `smoke req_004` | `lin.receive(id=0xFF, timeout=0.1)` (no matching frame queued) returns `None` and doesn't block longer than the requested timeout. |
+| `TestMockLinInterface::test_mock_frame_validation_boundaries[…]` | `boundary req_001 req_003` | Parametrized 4 ways: `(id, payload)` ∈ `{(0x01, [0x55]), (0x3F, [0xAA,0x55]), (0x20, 5 bytes), (0x15, 8 bytes)}`. Each frame round-trips through send/receive with byte-for-byte integrity. Covers the legal LIN ID and payload-length boundaries. |
+
+---
+
+### 2.2 `test_babylin_wrapper_mock.py` — BabyLIN adapter against a mocked SDK
+
+Source: [tests/test_babylin_wrapper_mock.py](tests/test_babylin_wrapper_mock.py)
+
+Constructs `BabyLinInterface(wrapper_module=mock_bl)` so the adapter exercises real code paths without needing the BabyLIN native library.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_babylin_sdk_adapter_with_mock_wrapper` | `babylin smoke req_001` | Connect (discover port, open, load SDF, start schedule) → `send(LinFrame(0x12, [0xAA,0x55,0x01]))` → `receive(timeout=0.1)`. The mock wrapper echoes the transmitted bytes; the test asserts ID and data round-trip. |
+| `test_babylin_master_request_with_mock_wrapper[…]` | `babylin smoke req_001` | Parametrized 2 ways. **`vendor.mock_babylin_wrapper-True`**: full mock with `BLC_sendRawMasterRequest(channel, id, length)` — expects the deterministic pattern. **`_MockBytesOnly-False`**: shim where only the bytes signature is supported; the adapter falls back to sending zeros and the response is asserted to be zeros of the requested length. Together these cover both SDK signatures the adapter must handle. |
+
+---
+
+## 3. Plugin self-test — `tests/plugin/`
+
+### 3.1 `test_conftest_plugin_artifacts.py`
+
+Source: [tests/plugin/test_conftest_plugin_artifacts.py](tests/plugin/test_conftest_plugin_artifacts.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_plugin_writes_artifacts` | `unit` | Uses pytest's `pytester` to run a synthetic test in a temp dir with the reporting plugin loaded. Asserts `reports/requirements_coverage.json` is created with `REQ-001` mapped, that `reports/summary.md` exists, and that the JSON references the generated `report.html` and `junit.xml`. Validates the plugin's full artifact pipeline end-to-end. |
+
+---
+
+## 4. Hardware – MUM (Melexis Universal Master)
+
+Tests gated on `interface.type == "mum"`. All require:
+
+- A reachable MUM (default `192.168.7.2` over USB-RNDIS)
+- Melexis `pylin` and `pymumclient` Python packages installed
+- An ECU wired to the MUM's `lin0` and powered through `power_out0`
+- `interface.ldf_path` pointing at the LDF that matches the ECU
+
+### 4.1 `test_e2e_mum_led_activate.py`
+
+Source: [tests/hardware/test_e2e_mum_led_activate.py](tests/hardware/test_e2e_mum_led_activate.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_mum_e2e_power_on_then_led_activate` | `hardware mum` | The "smoke + LED on" flow. Reads `ALM_Status`, decodes `ALMNadNo` via the LDF, builds an `ALM_Req_A` payload (full-white RGB at full intensity, immediate setpoint, mode 0) targeting that NAD, sends it, and re-reads `ALM_Status` to confirm the bus is still alive afterward. |
+
+**Notes:**
+
+- Power-up is implicit — the MUM `lin` fixture already calls `power_control.power_up()` on connect.
+- Frame layouts come from the `ldf` fixture, not hand-coded byte positions.
+
+### 4.2 `test_mum_alm_animation.py`
+
+Source: [tests/hardware/test_mum_alm_animation.py](tests/hardware/test_mum_alm_animation.py)
+
+Suite of automated checks for the four behaviour buckets in
+`vendor/automated_lin_test/test_animation.py`. A module-scoped fixture
+reads the ECU's NAD once; an `autouse` fixture forces an OFF baseline
+before and after every test so cases don't bleed state into each other.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_mode0_immediate_setpoint_drives_led_on` | `hardware mum` | `AmbLightMode=0`, bright RGB+I, target single NAD. Polls `ALMLEDState` and asserts it reaches `LED_ON` within ~1 s. |
+| `test_mode1_fade_passes_through_animating` | `hardware mum` | `AmbLightMode=1` with `AmbLightDuration=10` (≈ 2 s expected). Asserts `ALMLEDState` enters `ANIMATING` during the fade and reaches `LED_ON` afterward. |
+| `test_duration_scales_with_lsb[5-0.6]` / `[10-0.6]` | `hardware mum` | Parametrized: with `Duration=N`, the `ANIMATING` window must be within ±0.6 s of `N × 0.2 s`. Loose tolerance accounts for the 50 ms poll cadence and bus latency. |
+| `test_update1_save_does_not_apply_immediately` | `hardware mum` | `AmbLightUpdate=1` (Save) with bright payload — `ALMLEDState` must NOT transition to `ANIMATING` or `LED_ON`. Verifies save-only semantics. |
+| `test_update2_apply_runs_saved_command` | `hardware mum` | After a save (Update=1), an apply (Update=2) with throwaway payload should execute the saved command — `ANIMATING` is observed. |
+| `test_update3_discard_then_apply_is_noop` | `hardware mum` | Save → Discard (Update=3) → Apply. Apply must be a no-op (no `ANIMATING`, no `LED_ON`). Verifies the discard clears the saved buffer. |
+| `test_lid_broadcast_targets_node` | `hardware mum` | `AmbLightLIDFrom=0x00, AmbLightLIDTo=0xFF` with bright RGB. Node must react and reach `LED_ON`, regardless of its actual NAD. |
+| `test_lid_invalid_range_is_ignored` | `hardware mum` | `LIDFrom > LIDTo` (e.g. `0x14 > 0x0A`). Node must ignore the frame — `ALMLEDState` stays at OFF baseline. |
+
+**Caveats:**
+
+- Visual properties (color, smoothness of fade) cannot be asserted without a camera. These tests assert only what the LIN bus exposes (`ALMLEDState` transitions, ANIMATING duration). For a human-verified visual run, use the original `vendor/automated_lin_test/test_animation.py`.
+- `test_duration_scales_with_lsb` polls every 50 ms; the tolerance is intentionally loose. Tighten it once you've measured your firmware's actual jitter.
+
+### 4.3 `test_mum_auto_addressing.py`
+
+Source: [tests/hardware/test_mum_auto_addressing.py](tests/hardware/test_mum_auto_addressing.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_bsm_auto_addressing_changes_nad` | `hardware mum slow` | Drives the full BSM-SNPD sequence (INIT → 16× ASSIGN → STORE → FINALIZE) with a target NAD different from the ECU's current one, then re-reads `ALM_Status` and asserts `ALMNadNo == target`. Always restores the original NAD in a `finally` block (the restore result is recorded as report properties). Uses `lin.send_raw()` so the LIN 1.x **Classic** checksum is used — Enhanced would be silently rejected by the firmware. |
+
+**Notes:**
+
+- Marked `slow` because the full sequence runs in ~3-4 seconds (two BSM cycles plus settle). Skip with `-m "hardware and mum and not slow"`.
+- Restore is best-effort: if the second BSM cycle fails, the bench stays at the target NAD. The restore failure is visible as `restore_warning` / `restore_error` in the report properties.

+### 4.4 `test_e2e_power_on_lin_smoke.py` *(DEPRECATED, BabyLIN-marked)*
+
+Source: [tests/hardware/test_e2e_power_on_lin_smoke.py](tests/hardware/test_e2e_power_on_lin_smoke.py)
+
+Despite living in `tests/hardware/`, this file targets the **deprecated BabyLIN** adapter (it predates the MUM migration). See section 5.4.
+
+---
+
+## 5. Hardware – BabyLIN (DEPRECATED)
+
+> Retained only so existing BabyLIN rigs can keep running. New work should add tests under section 4 (Hardware – MUM).
+
+Tests gated on `interface.type == "babylin"` (deprecated). Require:
+
+- BabyLIN device + native libraries placed under `vendor/`
+- An SDF compiled from your LDF, path supplied via `interface.sdf_path`
+- For the E2E test: an Owon PSU on a serial port (the BabyLIN doesn't supply ECU power)
+
+### 5.1 `test_babylin_hardware_smoke.py`
+
+Source: [tests/test_babylin_hardware_smoke.py](tests/test_babylin_hardware_smoke.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_babylin_connect_receive_timeout` | `hardware babylin` | Minimal sanity: open the BabyLIN device via the configured `lin` fixture and call `lin.receive(timeout=0.2)`. Accepts either a `LinFrame` or `None` (timeout) — verifies the adapter is functional and not crashing. |
+
+### 5.2 `test_babylin_hardware_schedule_smoke.py`
+
+Source: [tests/test_babylin_hardware_schedule_smoke.py](tests/test_babylin_hardware_schedule_smoke.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_babylin_sdk_example_flow` | `hardware babylin smoke` | Verifies `interface.type == "babylin"` and an `sdf_path` is set, then exercises the receive path while the configured `schedule_nr` runs. Mirrors the vendor example flow (open / load SDF / start schedule / receive). Accepts either a frame or a timeout. |
+
+### 5.3 `test_hardware_placeholder.py`
+
+Source: [tests/test_hardware_placeholder.py](tests/test_hardware_placeholder.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_babylin_placeholder` | `hardware babylin` | Always passes. Used to confirm the marker filter and CI plumbing for hardware jobs without requiring any specific device behaviour. |
+
+### 5.4 `test_e2e_power_on_lin_smoke.py`
+
+Source: [tests/hardware/test_e2e_power_on_lin_smoke.py](tests/hardware/test_e2e_power_on_lin_smoke.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_e2e_power_on_then_cco_rgb_activate` | `hardware babylin` | Full BabyLIN E2E. Powers the ECU through the Owon PSU, switches to the LDF's `CCO` schedule via `lin.start_schedule("CCO")` (which resolves the schedule name to its index using `BLC_SDF_getScheduleNr`), publishes an `ALM_Req_A` payload with full-white RGB at full intensity, captures bus traffic for ~1 s, and asserts at least one frame was observed. Always disables PSU output in `finally`. |
+
+**Notes:**
+
+- This test was the original E2E target before the MUM migration. It still works as a BabyLIN smoke test if you flip `interface.type: babylin` and provide a valid SDF.
+- The Owon PSU section of `config.power_supply` must be enabled (`port`, `set_voltage`, `set_current`, `do_set: true`).

+
+### 6.1 `test_owon_psu.py`
+
+Source: [tests/hardware/test_owon_psu.py](tests/hardware/test_owon_psu.py)
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_owon_psu_idn_and_measurements` | `hardware` | Read-only smoke against the **session-managed** PSU (opened by `tests/hardware/conftest.py`). Queries `*IDN?` (asserts non-empty; checks `idn_substr` if configured), `output?` (asserts ON — the session fixture parked it that way), and the parsed-numeric helpers `measure_voltage_v()` / `measure_current_a()`. Verifies measured voltage is within ±10% of `cfg.set_voltage`. |
+
+**Notes:**
+
+- Does **not** toggle the output — that would brown out the ECU and break every test that follows in the same session. The toggle path is exercised once at session start by the conftest fixture.
+- Settings can live in `config/test_config.yaml` (central) or `config/owon_psu.yaml` (per-machine override; the latter wins).

+
+## 7. Hardware – Voltage tolerance (PSU + LIN)
+
+### 7.1 `test_overvolt.py`
+
+Source: [tests/hardware/test_overvolt.py](tests/hardware/test_overvolt.py)
+
+Drives the bench supply through known thresholds and observes
+`ALM_Status.ALMVoltageStatus` on the LIN bus. All cases use the
+SETUP / PROCEDURE / ASSERT / TEARDOWN four-phase pattern with a
+`try`/`finally` that restores nominal voltage. The session-scoped
+PSU stays open across every case; voltage is perturbed but output
+is never toggled.
+
+**Pattern (settle then validate).** Each PROCEDURE goes through
+`apply_voltage_and_settle()` from `psu_helpers`: set the target,
+**poll the PSU meter** until the rail is actually there, then hold
+for `ECU_VALIDATION_TIME_S` so the firmware can detect and republish
+status. After that, a single deterministic read of
+`ALMVoltageStatus` gives the answer — no polling-the-bus race. See
+`docs/14_power_supply.md` for the full pattern reference.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_template_overvoltage_status` | `hardware mum` | Confirm baseline `ALMVoltageStatus == Normal`, then `apply_voltage_and_settle(OVERVOLTAGE_V, ECU_VALIDATION_TIME_S)`, single read of status, assert `OverVoltage` (`0x02`). Restore nominal and verify recovery to `Normal`. |
+| `test_template_undervoltage_status` | `hardware mum` | Symmetric: apply `UNDERVOLTAGE_V`, settle + validation hold, assert `UnderVoltage` (`0x01`), restore. Failure message hints when the slave browns out before tripping the UV flag. |
+| `test_template_voltage_status_parametrized[nominal\|overvoltage\|undervoltage]` | `hardware mum` | One parametrized walk over `(voltage, expected_status, label)`. Each row runs SETUP/PROCEDURE/ASSERT/TEARDOWN independently via the autouse `_park_at_nominal` fixture. |
+
+**Report properties recorded per case:**
+- `psu_setpoint_v` — requested voltage
+- `psu_settled_s` — measured PSU slew time (bench-dependent)
+- `psu_final_v` — last measured voltage
+- `validation_time_s` — firmware-side hold (`ECU_VALIDATION_TIME_S`)
+- `voltage_status_after` — single status read used for the assertion
+- `voltage_trace` — downsampled `(elapsed_s, v)` trace from the settle phase
+
+**Notes:**
+
+- **Tune the constants at the top of the file** to your firmware spec: `NOMINAL_VOLTAGE`, `OVERVOLTAGE_V`, `UNDERVOLTAGE_V`, `ECU_VALIDATION_TIME_S`.
+- The autouse `_park_at_nominal` fixture also uses `apply_voltage_and_settle`, so the rail is *measurably* back at nominal before AND after every test — voltage cannot leak between cases.
+- `cfg.power_supply.do_set` is no longer required (the session fixture owns the PSU lifecycle); `enabled: true` and a reachable port are sufficient.
+
+### 7.2 `test_psu_voltage_settling.py` *(opt-in: `-m psu_settling`)*
+
+Source: [tests/hardware/test_psu_voltage_settling.py](tests/hardware/test_psu_voltage_settling.py)
+
+Characterization test — extracts how long the bench Owon PSU takes
+to actually deliver a new voltage at its terminals after a setpoint
+change. Other voltage-tolerance tests use the result to budget their
+detect timeouts. Marked `psu_settling` + `slow` so it stays out of
+default `-m hardware` runs unless explicitly selected.
+
+| Test | Markers | Purpose |
+| --- | --- | --- |
+| `test_psu_voltage_settling_time[13_to_18_OV]` | `hardware psu_settling slow` | Park PSU at 13 V (un-timed), then `set_voltage(18)` and poll `measure_voltage_v()` every 50 ms until within ±0.10 V of target or 10 s timeout. Records `settling_time_s` and a downsampled voltage trace. |
+| `test_psu_voltage_settling_time[18_to_13_back]` | same | The return path: 18 V → 13 V. Slewing down often differs from slewing up; both numbers are useful for budgeting. |
+| `test_psu_voltage_settling_time[13_to_7_UV]` | same | Nominal → undervoltage. |
+| `test_psu_voltage_settling_time[7_to_13_back]` | same | Undervoltage → nominal. |
+
+**Notes:**
+
+- Run via `pytest -m psu_settling -s` to see the per-case timing in stdout.
+- Per-case report properties: `settling_time_s`, `final_voltage_v`, `sample_count`, `voltage_trace` (downsampled to ~30 entries), plus the inputs (`start_voltage_v`, `target_voltage_v`, `voltage_tol_v`).
+- Each case ends by restoring `NOMINAL_V` (13 V) so subsequent tests don't inherit a perturbed setpoint.
+- Tune the four module-level constants (`VOLTAGE_TOL_V`, `POLL_INTERVAL_S`, `MAX_SETTLE_TIME_S`, `NOMINAL_V`) to your bench if defaults don't fit.
+
+---
+
+## 8. Hardware-test infrastructure (not collected as tests)
+
+These files support the suite but are not test bodies:
+
+### 8.1 `tests/hardware/conftest.py`
+
+Session-scoped fixtures:
+
+- `_psu_or_none` — opens the Owon PSU once via `resolve_port()` (cross-platform), parks at `cfg.power_supply.set_voltage` / `set_current`, enables output. Yields `OwonPSU` or `None` (tolerant: never raises out of fixture).
+- `_psu_powers_bench` — `autouse=True`. Realizes `_psu_or_none` so even tests that don't request `psu` by name benefit from the session power-up.
+- `psu` — public; skips cleanly when the PSU isn't available.
+
+Tests **must not** call `psu.set_output(False)` or `psu.close()` — the conftest owns the lifecycle. See `docs/14_power_supply.md` §5.
+
+### 8.2 `tests/hardware/frame_io.py` — `FrameIO`
+
+Generic LDF-driven I/O. Three layers (`send`/`receive`/`read_signal`, `pack`/`unpack`, `send_raw`/`receive_raw`) plus introspection (`frame_id`, `frame_length`). Reusable for any frame in any LDF — no ALM-specific knowledge.
+
+### 8.3 `tests/hardware/alm_helpers.py` — `AlmTester` + constants
+
+ALM_Node domain helpers built on `FrameIO`: `force_off`, `wait_for_state`, `measure_animating_window`, `read_led_state`, `assert_pwm_matches_rgb`, `assert_pwm_wo_comp_matches_rgb`. Plus pure utilities (`ntc_kelvin_to_celsius`, `pwm_within_tol`) and the LED-state / pacing / PWM-tolerance constants.
+
+### 8.4 `tests/hardware/psu_helpers.py` — settle-then-validate primitives
+
+Shared PSU helpers used by every test that changes the supply voltage:
+
+- `wait_until_settled(psu, target_v, *, tol, interval, timeout)` — polls `psu.measure_voltage_v()` until within `tol` of `target_v`, returns `(elapsed_s, trace)` or `(None, trace)` on timeout.
+- `apply_voltage_and_settle(psu, target_v, *, validation_time, ...)` — composite: issues the setpoint, calls `wait_until_settled`, then sleeps `validation_time` so the firmware-side observer can detect and republish. Returns `{settled_s, validation_s, final_v, trace}`. Raises `AssertionError` if the PSU can't reach the target.
+- `downsample_trace(trace, max_samples=30)` — utility to keep poll traces in report properties readable.
+
+Module-level defaults: `DEFAULT_VOLTAGE_TOL_V = 0.10`, `DEFAULT_POLL_INTERVAL_S = 0.05`, `DEFAULT_SETTLE_TIMEOUT_S = 10.0`, `DEFAULT_VALIDATION_TIME_S = 1.0`.
+
+Used by `test_overvolt.py`, `test_psu_voltage_settling.py`, and the `_test_case_template_psu_lin.py` template.
+
+### 8.5 Test starting points (leading underscore → not collected)
+
+- `tests/hardware/_test_case_template.py` — three flavors (minimal / with isolation / single-signal probe) for ALM-touching MUM tests.
+- `tests/hardware/_test_case_template_psu_lin.py` — three flavors (overvoltage / undervoltage / parametrized sweep) for tests that drive the PSU and observe the LIN bus.
+
+Both contain pedagogical inline comments explaining fixture scopes, autouse, `yield`, the four-phase test pattern, and per-flavor when-to-use guidance. Copy to `test_<feature>.py` and edit.
+
+---
+
+## Test naming conventions
+
+When adding new tests, follow these patterns so the catalog stays scannable:
+
+- **Unit tests** live in `tests/unit/` and carry `@pytest.mark.unit`. Filename starts with `test_<thing>_<scope>` (e.g., `test_mum_adapter_mocked.py`).
+- **Mock smoke tests** live in `tests/` and use either the in-process Mock adapter (override the `lin` fixture locally) or an injected SDK mock wrapper.
+- **Hardware tests** live in `tests/hardware/` (preferred) or `tests/` (legacy) and carry `@pytest.mark.hardware` plus an adapter marker (`mum` for current work, `babylin` for the deprecated path).
+- **Slow tests** (>5 s) carry `@pytest.mark.slow` so they can be excluded with `-m "not slow"`.
+- **Requirement traceability** is via `req_NNN` markers on the test function and a `Requirements:` line in the docstring (parsed by the reporting plugin).
+
+## Docstring format
+
+The reporting plugin extracts these fields from each test's docstring and renders them in the HTML report:
+
+```python
+"""
+Title: <short title>
+
+Description:
+    <what the test validates and why>
+
+Requirements: REQ-001, REQ-002
+
+Test Steps:
+    1. <step one>
+    2. <step two>
+
+Expected Result:
+    <succinct expected outcome>
+"""

+# Hardware Test Helpers — `FrameIO` and `AlmTester`
+
+Hardware tests under `tests/hardware/` use two helper modules to keep test
+bodies focused on intent rather than bus mechanics:
+
+| Module | Scope | What it gives you |
+| --- | --- | --- |
+| [`tests/hardware/frame_io.py`](../tests/hardware/frame_io.py) | **Generic LDF I/O** | `FrameIO` class — send/receive any LDF-defined frame by name, plus pack/unpack and raw-bus escape hatches. Knows nothing about ALM. |
+| [`tests/hardware/alm_helpers.py`](../tests/hardware/alm_helpers.py) | **ALM_Node domain** | `AlmTester` class + constants + pure utilities. Encodes the test patterns specific to the ALM_Req_A / ALM_Status / PWM_Frame / PWM_wo_Comp / Tj_Frame / ConfigFrame set. Built on `FrameIO`. |
+
+The split lets the same `FrameIO` class be reused by future test suites for
+other ECUs while keeping ALM-specific knowledge in one place.
+
+---
+
+## 1. Three layers of access
+
+`FrameIO` exposes the same bus three ways. A test picks whichever layer
+matches its intent.
+
+### 1.1 High level — by frame and signal name
+
+This is the default for almost every test. The LDF carries the frame ID,
+length, and signal layout, so the test code never mentions any of those.
+
+```python
+fio.send(
+    "ALM_Req_A",
+    AmbLightColourRed=255, AmbLightColourGreen=0, AmbLightColourBlue=0,
+    AmbLightIntensity=255,
+    AmbLightUpdate=0, AmbLightMode=0, AmbLightDuration=10,
+    AmbLightLIDFrom=alm.nad, AmbLightLIDTo=alm.nad,
+)
+
+decoded = fio.receive("ALM_Status")           # full dict of decoded signals
+nad     = fio.read_signal("ALM_Status", "ALMNadNo")   # one signal
+```
+
+### 1.2 Mid level — pack / unpack without I/O
+
+Use this when you want to build a payload, inspect or modify it, and then
+send it (often via the low-level path).
+
+```python
+data = bytearray(fio.pack("ALM_Req_A", AmbLightColourRed=255, ...))
+data[7] |= 0x80                                    # tweak a bit by hand
+fio.send_raw(fio.frame_id("ALM_Req_A"), bytes(data))
+
+# Decode raw bytes you already have:
+decoded = fio.unpack("PWM_Frame", b"\x12\x34..." )
+```
+
+### 1.3 Low level — raw bus, bypass the LDF
+
+For cases the LDF doesn't describe, or when you need full control.
+
+```python
+fio.send_raw(0x12, bytes([0x00] * 8))
+rx = fio.receive_raw(0x11, timeout=0.5)            # returns LinFrame | None
+```
+
+### 1.4 Introspection
+
+```python
+fio.frame_id("PWM_Frame")        # 0x12
+fio.frame_length("PWM_Frame")    # 8
+fio.frame("PWM_Frame")           # raw ldfparser Frame object (cached)
+fio.lin                          # underlying LinInterface
+fio.ldf                          # LdfDatabase
+```
+
+---
+
+## 2. `FrameIO` API reference
+
+```python
+class FrameIO:
+    def __init__(self, lin: LinInterface, ldf): ...
+
+    # high level
+    def send(self, frame_name: str, **signals) -> None
+    def receive(self, frame_name: str, timeout: float = 1.0) -> dict | None
+    def read_signal(self, frame_name: str, signal_name: str, *,
+                    timeout: float = 1.0, default=None) -> Any
+
+    # mid level
+    def pack(self, frame_name: str, **signals) -> bytes
+    def unpack(self, frame_name: str, data: bytes) -> dict
+
+    # low level
+    def send_raw(self, frame_id: int, data: bytes) -> None
+    def receive_raw(self, frame_id: int, timeout: float = 1.0) -> LinFrame | None
+
+    # introspection
+    def frame(self, name: str)
+    def frame_id(self, name: str) -> int
+    def frame_length(self, name: str) -> int
+
+    # injected refs
+    @property
+    def lin(self) -> LinInterface
+    @property
+    def ldf(self)
+```
+
+Notes:
+
+- `send()` / `pack()` require **every** signal in the frame; ldfparser
+  raises if one is missing. Use `receive()` first if you want to merge a
+  change into the current state.
+- `receive()` returns `None` on timeout (rather than raising), so polling
+  loops stay simple.
+- All frame lookups are cached per `FrameIO` instance — repeated calls to
+  `send`/`receive`/`frame` for the same name don't re-walk the LDF.
+
+---
+
+## 3. `AlmTester` API reference
+
+`AlmTester` bundles a `FrameIO` and a NAD, and exposes ALM-specific test
+patterns. Build it once in a fixture and pass it into tests.
+
+```python
+class AlmTester:
+    def __init__(self, fio: FrameIO, nad: int): ...
+
+    @property
+    def fio(self) -> FrameIO            # the underlying FrameIO
+    @property
+    def nad(self) -> int                # bound node NAD
+
+    # ALM_Status polling
+    def read_led_state(self, timeout: float = STATE_RECEIVE_TIMEOUT) -> int
+    def wait_for_state(self, target: int, timeout: float
+                       ) -> tuple[bool, float, list[int]]
+    def measure_animating_window(self, max_wait: float
+                                 ) -> tuple[float | None, list[int]]
+
+    # LED control
+    def force_off(self) -> None         # drives mode=0, intensity=0; sleeps to settle
+
+    # PWM assertions (use rgb_to_pwm.compute_pwm() under the hood)
+    def assert_pwm_matches_rgb(self, rp, r, g, b, *, label: str = "") -> None
+    def assert_pwm_wo_comp_matches_rgb(self, rp, r, g, b, *, label: str = "") -> None
+```
+
+The `assert_pwm_*` helpers:
+
+- Read `Tj_Frame_NTC` (Kelvin), convert to °C, and pass it to `compute_pwm`
+  so temperature compensation matches what the ECU is applying.
+- Sleep `PWM_SETTLE_SECONDS` (10 LIN frame periods) before reading PWM
+  frames so the slave's TX buffer has time to refresh.
+- Record both expected and actual values as report properties via the
+  `rp(...)` helper from `tests/conftest.py`. The optional `label`
+  parameter lets you append a suffix when you assert PWM more than once
+  in the same test.
+
+---
+
+## 4. Constants and utilities (in `alm_helpers`)
+
+```python
+# ALMLEDState (from LDF Signal_encoding_types: LED_State)
+LED_STATE_OFF        = 0
+LED_STATE_ANIMATING  = 1
+LED_STATE_ON         = 2
+
+# Test pacing — chosen against the 10 ms LIN frame periodicity
+STATE_POLL_INTERVAL       = 0.05    # 50 ms between polls (5 LIN periods)
+STATE_RECEIVE_TIMEOUT     = 0.2     # per-poll receive timeout
+STATE_TIMEOUT_DEFAULT     = 1.0     # default wait_for_state ceiling
+PWM_SETTLE_SECONDS        = 0.1     # let the slave refresh PWM_Frame TX buffer
+DURATION_LSB_SECONDS      = 0.2     # AmbLightDuration scale: 1 LSB = 200 ms
+FORCE_OFF_SETTLE_SECONDS  = 0.4     # pause after the OFF command
+
+# PWM tolerances
+KELVIN_TO_CELSIUS_OFFSET = 273.15
+PWM_ABS_TOL = 3277      # ±5% of 16-bit full scale
+PWM_REL_TOL = 0.05      # ±5% of expected, whichever is larger
+
+# Pure utilities
+def ntc_kelvin_to_celsius(ntc_raw: int) -> float
+def pwm_within_tol(actual: int, expected: int) -> bool
+```
+
+---
+
+## 5. Fixture wiring
+
+`tests/hardware/test_mum_alm_animation.py` defines two module-scoped
+fixtures plus an autouse reset. The same pattern applies to any new
+hardware test file targeting MUM.
+
+```python
+import pytest
+from ecu_framework.config import EcuTestConfig
+from ecu_framework.lin.base import LinInterface
+from frame_io import FrameIO
+from alm_helpers import AlmTester
+
+
+@pytest.fixture(scope="module")
+def fio(config: EcuTestConfig, lin: LinInterface, ldf) -> FrameIO:
+    if config.interface.type != "mum":
+        pytest.skip("interface.type must be 'mum' for this suite")
+    return FrameIO(lin, ldf)
+
+
+@pytest.fixture(scope="module")
+def alm(fio: FrameIO) -> AlmTester:
+    decoded = fio.receive("ALM_Status", timeout=1.0)
+    if decoded is None:
+        pytest.skip("ECU not responding on ALM_Status — check wiring/power")
+    nad = int(decoded["ALMNadNo"])
+    if not (0x01 <= nad <= 0xFE):
+        pytest.skip(f"ECU reports invalid NAD {nad:#x} — auto-addressing first")
+    return AlmTester(fio, nad)
+
+
+@pytest.fixture(autouse=True)
+def _reset_to_off(alm: AlmTester):
+    """Force LED OFF before and after each test so state doesn't leak."""

+
+## 7. Writing a new test
+
+### 7.1 Starting point
+
+A heavily-annotated, copyable template lives at
+[`tests/hardware/_test_case_template.py`](../tests/hardware/_test_case_template.py).
+The leading underscore stops pytest from collecting it, so the example
+bodies don't run on the bench.
+
+Copy it to a new file named `test_<feature>.py` under `tests/hardware/`
+and edit. The template includes:
+
+- The standard imports for `frame_io` and `alm_helpers`
+- The three module-level fixtures (`fio`, `alm`, `_reset_to_off`) with
+  inline explanations of fixture scope, `autouse`, and `yield`
+- Three skeleton bodies (one per common shape — see §7.3)
+- An appendix listing the most-reached-for patterns
+
+### 7.2 The four-phase test pattern
+
+Every hardware test that mutates ECU state beyond just the LED should
+follow a **SETUP / PROCEDURE / ASSERT / TEARDOWN** structure with a
+`try`/`finally` so the teardown runs even when an assertion fails.
+
+```python
+def test_xyz(fio, alm, rp):
+    """..."""
+    # ── SETUP ──────────────────────────────────────
+    # Bring the ECU to the exact state THIS test needs, beyond what the
+    # autouse reset already gave us. Anything you change here MUST be
+    # undone in TEARDOWN below.
+    fio.send("ConfigFrame", ConfigFrame_EnableCompensation=0, ...)
+    time.sleep(0.2)
+
+    try:
+        # ── PROCEDURE ──────────────────────────────
+        # The actions whose effects you are validating.
+        fio.send("ALM_Req_A", ...)
+        reached, _, history = alm.wait_for_state(LED_STATE_ON, timeout=1.0)
+
+        # ── ASSERT ─────────────────────────────────
+        # Bus-observable expectations. Use `rp("key", value)` to attach
+        # diagnostics to the report, then assert.
+        rp("led_state_history", history)
+        assert reached, history
+        alm.assert_pwm_wo_comp_matches_rgb(rp, r, g, b)
+
+    finally:
+        # ── TEARDOWN ───────────────────────────────
+        # Always runs. Restores anything SETUP perturbed.
+        fio.send("ConfigFrame", ConfigFrame_EnableCompensation=1, ...)
+        time.sleep(0.2)
+```
+
+### Why this gives you test independence
+
+Pytest runs tests in a deterministic order (the order they appear in the
+file). Without strict teardown, a failure midway through one test can
+leave the ECU in a non-default state that breaks every subsequent test
+— turning a single bug into a cascade. The four-phase pattern prevents
+that with two layers:
+
+| Layer | What it covers | Where it lives |
+|---|---|---|
+| Common baseline | LED → OFF | autouse `_reset_to_off` fixture |
+| Per-test specifics | ConfigFrame, schedules, mode flags, anything else | the test's own `try`/`finally` |
+
+The autouse fixture handles the universal baseline so individual tests
+don't have to think about it; the per-test `try`/`finally` handles
+whatever that specific test mutated.
+
+### When you can skip the four phases
+
+If your test only sends a frame and observes the LED state (i.e. the
+*only* mutable state involved is something the autouse reset already
+restores), the explicit SETUP/TEARDOWN sections are dead weight — just
+write the procedure straight through. Flavor A in the template
+illustrates this minimal shape.
+
+### 7.3 Three flavors in the template
+
+| Flavor | When to use it |
+|---|---|
+| **A — minimal** | Test only drives the LED and asserts on PWM/state. The autouse reset is enough. |
+| **B — with isolation** | Test changes any persistent ECU state (ConfigFrame, schedules, NAD, …). Use the `try`/`finally` pattern. |
+| **C — single-signal probe** | "Ask the ECU one thing and check the answer." Uses `fio.read_signal(...)`, no state mutation. |
+
+Pick the closest one, delete the others, rename the function and fill
+in the docstring.
+
+### 7.4 Tests that drive the PSU and observe the LIN bus
+
+For *combined* PSU + LIN scenarios (overvoltage / undervoltage
+tolerance, brown-out behaviour, supply transients) there is a
+dedicated template at
+[`tests/hardware/_test_case_template_psu_lin.py`](../tests/hardware/_test_case_template_psu_lin.py).
+It adds a `psu` fixture (cross-platform port resolution + safe-off
+on close), an autouse `_park_at_nominal` fixture, a
+`wait_for_voltage_status` polling helper, and three flavors:
+
+| Flavor | Demonstrates |
+|---|---|
+| A — overvoltage | Drive PSU above the OV threshold, expect `ALMVoltageStatus = 0x02`, restore. |
+| B — undervoltage | Symmetric for UV (`0x01`). |
+| C — sweep | Parametrized walk over `(V, expected_status)` tuples. |
+
+For the *settling time* characterization that feeds these tests'
+detect timeouts, see `tests/hardware/test_psu_voltage_settling.py`
+(opt-in via `pytest -m psu_settling`).
+
+See [`docs/14_power_supply.md` §6](14_power_supply.md#6-run-the-hardware-test) and [§5 (session-managed power)](14_power_supply.md#5-session-managed-power-the-bench-powers-the-ecu-through-the-psu)
+for the full reference and the constants to tune for your firmware.

+

+
+The wrapper uses `encode_raw` / `decode_raw` rather than `encode` / `decode`
+so signal *encoding types* (logical/physical conversions) are bypassed —
+tests work with raw integer values, which is what `LinFrame.data` carries.
+If you need encoding-type interpretation, use `Frame.encode()` /

+"""LIN adapter that uses the Melexis Universal Master (MUM) over the network.
+
+Wraps the vendor's `pylin` + `pymumclient` packages so test code can talk to
+the MUM through the same `LinInterface` abstraction used by the BabyLIN and
+mock adapters. The MUM is a BeagleBone-based LIN master reachable over IP
+(default 192.168.7.2) with built-in power control on `power_out0`.
+
+The MUM is master-driven: a slave frame is fetched by issuing a request via
+`send_message(master_to_slave=False, frame_id, data_length)`, so `receive()`
+requires a frame ID. Per-frame `data_length` is taken from the constructor's
+`frame_lengths` map; ALM_Status (0x11, 4 bytes) and ALM_Req_A (0x0A, 8 bytes)
+have built-in defaults so the common cases work out of the box.
+
+Diagnostic frames (BSM-SNPD) need the LIN 1.x **Classic** checksum, which
+`send_message` does not produce. Use `send_raw()` (which calls the transport
+layer's `ld_put_raw`) for those frames.

+
+WHAT THIS MODULE GIVES YOU
+--------------------------
+- :class:`SerialParams` — a small dataclass for the pyserial settings.
+  Construct directly, or use :meth:`SerialParams.from_config` to build
+  one from the project's central PSU configuration.
+- :class:`OwonPSU`      — context-managed controller. Wraps a serial
+  port and exposes the PSU's SCPI dialect as Python methods.
+- :func:`scan_ports`    — probe every serial port on the host for a
+  device that answers ``*IDN?``.
+- :func:`auto_detect`   — pick a port by IDN substring, or fall back
+  to the first responder.
+
+THE SCPI DIALECT THIS PSU EXPECTS
+---------------------------------
+Owon's PSU firmware speaks a near-SCPI dialect over a plain newline-
+terminated serial link. The commands this module uses (matching the
+working bench example):
+
+    *IDN?              → identification string
+    output 1 / output 0 → enable / disable the output (lowercase, NOT
+                          the standard ``OUTP ON`` / ``OUTP OFF``)
+    output?            → output state (returns 'ON'/'OFF' or '1'/'0')
+    SOUR:VOLT <V>      → set the voltage setpoint, volts
+    SOUR:CURR <A>      → set the current limit, amps
+    MEAS:VOLT?         → read measured voltage (string, may include 'V')
+    MEAS:CURR?         → read measured current (string, may include 'A')
+
+Both commands and queries are terminated with ``\\n`` (configurable via
+the ``eol`` argument). Queries use ``readline()`` to fetch a single-
+line response.
+
+SAFETY: ``OwonPSU`` defaults to ``safe_off_on_close=True``, which sends
+``output 0`` before closing the port. That way an aborted test or an
+exception cannot leave the bench powered on after the controller is
+disposed.

+"""Copyable starting point for new MUM hardware tests.
+
+WHY THE NAME STARTS WITH AN UNDERSCORE
+--------------------------------------
+pytest only collects files whose name matches ``test_*.py`` (configured
+in ``pytest.ini``). Because this file is named ``_test_case_template.py``
+(leading underscore), pytest skips it — so the example bodies below
+won't accidentally run on your bench.
+
+HOW TO USE THIS FILE
+--------------------
+1. Copy this file to ``tests/hardware/test_<feature>.py``.
+2. Rename ``test_template_*`` functions to describe what they verify
+   (e.g. ``test_blue_at_full_intensity_drives_pwm``).
+3. Fill in each docstring's ``Title / Description / Test Steps /
+   Expected Result`` block — the conftest plugin parses those into the
+   HTML report's metadata columns.
+4. Decide which template body matches your test (see TEST FLAVORS below)
+   and delete the others.
+5. Use ``fio`` for generic LDF-driven I/O; use ``alm`` for ALM_Node
+   patterns. Full reference: ``docs/19_frame_io_and_alm_helpers.md``.
+
+TEST FLAVORS PROVIDED BELOW
+---------------------------
+Three example bodies cover the most common shapes:
+
+  A) ``test_template_minimal`` — relies on the autouse reset; no
+     per-test setup or teardown. Use this when the test only sends
+     a frame, observes a state change, and asserts on PWM.
+
+  B) ``test_template_with_isolation`` — uses the explicit four-phase
+     SETUP / PROCEDURE / ASSERT / TEARDOWN pattern with try/finally so
+     the test stays independent of the others even if it mutates
+     persistent ECU state (e.g. ConfigFrame). **Use this for any test
+     that changes a value the autouse reset doesn't restore.**
+
+  C) ``test_template_signal_probe`` — short pattern for "read one
+     signal, assert something about it" cases.
+
+THE FOUR-PHASE PATTERN (read this once, the comments below assume it)
+---------------------------------------------------------------------
+Each test body in flavor B is split into four labelled sections:
+
+  • SETUP      — bring the ECU to the *exact* state this test needs
+                  beyond the common baseline already provided by the
+                  autouse fixture. Anything you change here MUST be
+                  undone in TEARDOWN.
+
+  • PROCEDURE  — the actions under test (sending a frame, waiting for
+                  a state, etc.). Should be readable top-to-bottom as
+                  the steps of the requirement you are verifying.
+
+  • ASSERT     — bus-observable expectations. Use ``rp("key", value)``
+                  to attach data to the report, then ``assert ...`` for
+                  the actual check.
+
+  • TEARDOWN   — runs in a ``finally`` so it executes even when an
+                  assertion fails. Restores any state that SETUP
+                  perturbed. This is what guarantees test independence.
+
+Tests in flavor A skip SETUP/TEARDOWN because the autouse
+``_reset_to_off`` fixture is enough — the LED is forced OFF before and
+after every test.

+"""Copyable template for tests that drive the PSU and observe the LIN bus.
+
+WHEN TO USE THIS TEMPLATE
+-------------------------
+Voltage-tolerance, brown-out, over-voltage, and "supply transient"
+tests can't be done from either side alone — you need to *perturb*
+the bench supply (Owon PSU) and *observe* the ECU's reaction on the
+LIN bus. This template wires both ends together with the
+SETUP / PROCEDURE / ASSERT / TEARDOWN pattern so the test stays
+independent of the others even when it raises mid-flight.
+
+THE CANONICAL PATTERN — settle then validate
+--------------------------------------------
+The Owon PSU does NOT slew instantaneously, and the slew time is
+**bench-dependent** (PSU model, load, cable drop). Don't sleep a
+fixed amount and assume the rail is there — *measure*. Every voltage
+change in this template goes through
+:func:`apply_voltage_and_settle` from ``psu_helpers``, which:
+
+  1. Issues the setpoint.
+  2. **Polls** ``measure_voltage_v()`` until the rail is actually at
+     the target (within ``DEFAULT_VOLTAGE_TOL_V``, or raises on
+     timeout).
+  3. Holds for ``ECU_VALIDATION_TIME_S`` so the firmware-side voltage
+     monitor can detect, debounce, and republish status.
+
+After that, a **single read** of ``ALM_Status.ALMVoltageStatus``
+gives an unambiguous answer — no polling-on-the-bus race.
+
+THREE FLAVORS PROVIDED
+----------------------
+  A) ``test_template_overvoltage_status``  — overvoltage detection.
+  B) ``test_template_undervoltage_status`` — undervoltage detection.
+  C) ``test_template_voltage_status_parametrized`` — sweep.
+
+WHY THE NAME STARTS WITH AN UNDERSCORE
+--------------------------------------
+pytest only collects ``test_*.py``; this file's leading underscore
+keeps the example bodies out of the suite. Copy to
+``test_<feature>.py`` and edit.
+
+SAFETY — three layers keep the bench safe
+-----------------------------------------
+  1. The session-scoped ``psu`` fixture (in
+     ``tests/hardware/conftest.py``) parks the supply at nominal
+     voltage with output ON at session start, and closes with
+     ``output 0`` at session end (``safe_off_on_close=True``).
+  2. The autouse ``_park_at_nominal`` fixture in this file restores
+     nominal voltage before AND after every test in this module —
+     also via ``apply_voltage_and_settle`` so the rail is *measurably*
+     back at nominal before the next test runs.
+  3. Every test wraps its voltage change in ``try``/``finally`` that
+     restores nominal so an assertion failure cannot leave the bench
+     at an over/undervoltage rail.
+
+WHY ``set_output`` IS NEVER CALLED HERE
+---------------------------------------
+On this bench the Owon PSU **powers the ECU**. Calling
+``psu.set_output(False)`` mid-session would brown out the ECU and
+break every test that runs afterwards. The session fixture enables
+the output once at session start; tests perturb voltage but never
+toggle the output state.

+
+WHY THIS FILE EXISTS
+--------------------
+On this bench the Owon PSU **powers the ECU** — the MUM only carries
+LIN traffic. So the PSU output must stay on for the **entire** test
+session, not just for the duration of an individual PSU test. If
+each test file opened/closed its own PSU connection (which by
+default sends ``output 0`` on close) the bench would brown out
+between modules and every subsequent MUM test would fail.
+
+WHAT THIS FILE PROVIDES
+-----------------------
+- ``_psu_or_none``       : session-scoped, tolerant. Opens the PSU
+                          once at session start, parks it at the
+                          configured nominal voltage, enables output,
+                          and leaves it that way for the whole
+                          session. Yields the live ``OwonPSU`` or
+                          ``None`` if the PSU isn't reachable.
+- ``_psu_powers_bench``  : session-scoped, ``autouse=True``. Realizes
+                          ``_psu_or_none`` so even tests that don't
+                          request the PSU by name benefit from the
+                          power-up. No-op when PSU isn't configured.
+- ``psu``                : session-scoped, public. Tests that read
+                          measurements or perturb voltage request
+                          this fixture; it skips cleanly when the
+                          PSU isn't available.
+
+CONTRACT FOR TESTS
+------------------
+Tests SHOULD:
+  - request ``psu`` if they need to read measurements or change voltage
+  - restore the bench to nominal voltage in their ``finally`` block
+    (the session fixture will not restore between tests)
+
+Tests MUST NOT:
+  - call ``psu.set_output(False)`` — this kills the ECU power for
+    every test that follows in the same session
+  - call ``psu.close()`` — the session fixture owns the lifecycle

+The Owon PSU does not slew instantaneously, and the slew time depends on

+        publishes an RGB activation payload on ALM_Req_A (ID 0x0A). Captures
+        bus traffic for a short window to confirm activity (typically the

+  4. FINALIZE subf=0x04, params=(0x02, 0xFF)              wait 20 ms
+
+Each frame is 8 bytes:

+the ECU firmware checks. `MumLinInterface.send_raw()` routes through the
+transport layer's `ld_put_raw`, which uses Classic; `lin.send()` would use
+Enhanced and frames would be silently rejected.

+"""Voltage-tolerance tests: drive the PSU and observe the LIN bus.
+
+WHAT THIS FILE COVERS
+---------------------
+Voltage-tolerance, brown-out, over-voltage, and "supply transient"
+behaviour. Tests perturb the bench supply (Owon PSU) and observe the
+ECU's reaction on the LIN bus, using the
+SETUP / PROCEDURE / ASSERT / TEARDOWN pattern so each case stays
+independent of the others even when it raises mid-flight.
+
+PATTERN — settle-then-validate
+------------------------------
+The Owon PSU does NOT slew instantaneously, and the slew time depends
+on the bench (PSU model, load, cable drop). The test_psu_voltage_settling
+characterization showed e.g. up-step ≠ down-step time. Instead of
+guessing a fixed sleep, every voltage change in this file goes through
+:func:`apply_voltage_and_settle` from ``psu_helpers``, which:
+
+  1. Issues the setpoint.
+  2. **Polls** ``measure_voltage_v()`` until the rail is actually at
+     the target (within tolerance, or raises on timeout).
+  3. Holds for ``ECU_VALIDATION_TIME_S`` so the firmware-side voltage
+     monitor can detect and republish status.
+
+After that, a **single read** of ``ALM_Status.ALMVoltageStatus``
+gives an unambiguous answer — no polling-on-the-bus race.
+
+THREE FLAVORS
+-------------
+  A) ``test_template_overvoltage_status``  — over-voltage detection.
+  B) ``test_template_undervoltage_status`` — under-voltage detection.
+  C) ``test_template_voltage_status_parametrized`` — sweep.
+
+SAFETY — three layers keep the bench safe
+-----------------------------------------
+  1. The session-scoped ``psu`` fixture (in
+     ``tests/hardware/conftest.py``) parks the supply at nominal
+     voltage with output ON at session start, and closes with
+     ``output 0`` at session end (``safe_off_on_close=True``).
+  2. The autouse ``_park_at_nominal`` fixture in this file restores
+     nominal voltage before AND after every test in this module
+     (using the same settle helper, so the next test starts steady).
+  3. Every test wraps its voltage change in ``try``/``finally`` so an
+     assertion failure cannot leave the bench at an over/undervoltage
+     rail.
+
+NEVER call ``psu.set_output(False)`` or ``psu.close()`` from a test —
+the Owon PSU powers the ECU on this bench, so toggling output kills
+LIN communication for every test that follows in the same session.
+The session fixture owns the PSU lifecycle.

+"""PSU voltage settling-time characterization.
+
+WHAT THIS TEST DOES
+-------------------
+Measures how long the bench Owon PSU actually takes to deliver a new
+voltage at its output terminals after a setpoint change. Other tests
+(notably ``test_overvolt.py``) rely on a settle delay before they read
+``ALMVoltageStatus``; this characterization gives you the real number
+to budget for instead of guessing.
+
+HOW IT WORKS
+------------
+For each parametrized transition ``start_v → target_v``:
+
+  1. SETUP    — park the PSU at ``start_v`` and wait, *un-timed*, until
+                the measured voltage actually settles there. This step
+                isolates the timer from any leftover state from the
+                previous test.
+  2. PROCEDURE — issue ``set_voltage(target_v)`` and immediately begin
+                polling ``psu.measure_voltage_v()`` at
+                ``POLL_INTERVAL_S``; the timer starts the moment the
+                setpoint is sent.
+  3. ASSERT   — record ``settling_time_s`` (and the full voltage
+                trace) as report properties; assert that the PSU
+                actually reached the target within
+                ``MAX_SETTLE_TIME_S``.
+  4. TEARDOWN — set the supply back to ``NOMINAL_V`` so subsequent
+                tests start from the bench's normal state.
+
+WHY THIS DESERVES ITS OWN MARKER (``psu_settling``)
+---------------------------------------------------
+The test takes tens of seconds (4 transitions × several seconds each)
+and is only useful occasionally — typically when changing the bench
+PSU model or when other voltage-tolerance tests start failing on the
+detect timeout. Selecting it explicitly with ``-m psu_settling``
+keeps everyday MUM/PSU runs fast.
+
+It's also marked ``slow`` so default ``-m hardware`` runs that pass
+``-m "not slow"`` skip it without the user having to know it exists.
+

+
+/**
+ * @addtogroup ua Unified Access
+ * @brief In the Unified Access interface the available features and values are structured in a tree
+ * of objects.
+ *
+ * @details
+ * Every object may have children, properties and methods, that are accessible through the __path__
+ * parameter of the functions. The children, properties and methods are identified by __tags__.
+ * Those tags are handle specific and described in this document. Additionally they can be listed by
+ * calling @ref BLC_discover with the handle you are interested in.
+ *
+ * ### Creation of new Objects
+ *  To add a new Object into the tree use the @ref BLC_createHandle function. To create a new object
+ * a using __key value pairs__ ("<key>=<value>") is required. In a path each key value pair has to
+ * be separated by one space character. Tags valid for the creation keys can be taken from the
+ * "Creat tags" tables of the Objects documented in this document. The value is specifying the name
+ * property of the new child. Additionally key value pairs with property tags can be appended, to
+ * set properties during the object creation, so that less calls to the Setters are required
+ * afterwards. e.g. creating a @ref ua_protocol_iso_tp in a @ref ua_channel with the name "my_dtl" :
+ * ~~~.c
+ * BL_HANDLE protocol_handle;
+ * BLC_createHandle(channel_handle, "new_iso_tp_protocol=my_dtl",
+ * &protocol_handle);
+ * ~~~
+ *
+ * ### Handles of existing Objects
+ *  To find an existing Object in the tree use the @ref BLC_createHandle function. Navigating the
+ * tree is done by constructing a path by using __key value pairs__ ("<key>=<value>"). Tags valid
+ * for the keys can be taken from the "Child tags" tables of the Objects documented in this
+ * document. In a path each key value pair has to be separated by one space character. e.g. getting
+ * the handle to the previously created @ref ua_protocol_iso_tp of that @ref ua_channel :
+ * ~~~.c
+ * BL_HANDLE protocol_handle;
+ * BLC_createHandle(channel_handle, "protocol=my_dtl", &protocol_handle);
+ * ~~~
+ *
+ * ### Getters
+ *  To read values of properties use @ref BLC_getSignedNumber, @ref BLC_getUnsignedNumber or @ref
+ * BLC_getBinary functions. The __path__ parameter has to end with the tag identifying the property
+ * to read. Valid tags can be taken from the "Property tags" tables of the Objects documented in
+ * this document. e.g. reading the requestFrameID from a @ref ua_service_iso_tp :
+ * ~~~.c
+ * uint64_t requestFrameID;
+ * BLC_getUnsignedNumber(service_handle, "req_frame_id", &requestFrameID);
+ * ~~~
+ *
+ * ### Setters
+ *  To store values of properties use @ref BLC_setSignedNumber, @ref BLC_setUnsignedNumber, @ref
+ * BLC_setBinary or @ref BLC_setCallback functions. The __path__ parameter has to end with the tag
+ * identifying the property to store. Valid tags can be taken from the "Property tags" tables of the
+ * Objects documented in this document. e.g. setting the requestFrameID of a @ref ua_service_iso_tp
+ * to 59 :
+ * ~~~.c
+ * BLC_setUnsignedNumber(service_handle, "req_frame_id", 59);
+ * ~~~
+ *
+ * ### Execution of Methods
+ *  To execute an object's method use @ref BLC_execute or @ref BLC_execute_async functions. In the
+ * path variable only the identifying tag is required. Valid tags can be taken from the "Method
+ * tags" tables of the Objects documented in this document. Functions might have parameters. Those
+ * can be specified by appending key value pairs to the path in the same manner as when creating new
+ * objects. The order of the parameters is not relevant. In some cases a synchronous call is not
+ * applicable, in these cases use @ref BLC_execute_async to execute the method in a dedicated
+ * thread. e.g. executing a @ref ua_service_iso_tp :
+ * ~~~.c
+ * BLC_execute(service_handle, "execute");
+ * ~~~

+
+/**
+ * @addtogroup ua Unified Access
+ * @brief In the Unified Access interface the available features and values are structured in a tree
+ * of objects.
+ *
+ * @details
+ * Every object may have children, properties and methods, that are accessible through the __path__
+ * parameter of the functions. The children, properties and methods are identified by __tags__.
+ * Those tags are handle specific and described in this document. Additionally they can be listed by
+ * calling @ref BLC_discover with the handle you are interested in.
+ *
+ * ### Creation of new Objects
+ *  To add a new Object into the tree use the @ref BLC_createHandle function. To create a new object
+ * a using __key value pairs__ ("<key>=<value>") is required. In a path each key value pair has to
+ * be separated by one space character. Tags valid for the creation keys can be taken from the
+ * "Creat tags" tables of the Objects documented in this document. The value is specifying the name
+ * property of the new child. Additionally key value pairs with property tags can be appended, to
+ * set properties during the object creation, so that less calls to the Setters are required
+ * afterwards. e.g. creating a @ref ua_protocol_iso_tp in a @ref ua_channel with the name "my_dtl" :
+ * ~~~.c
+ * BL_HANDLE protocol_handle;
+ * BLC_createHandle(channel_handle, "new_iso_tp_protocol=my_dtl",
+ * &protocol_handle);
+ * ~~~
+ *
+ * ### Handles of existing Objects
+ *  To find an existing Object in the tree use the @ref BLC_createHandle function. Navigating the
+ * tree is done by constructing a path by using __key value pairs__ ("<key>=<value>"). Tags valid
+ * for the keys can be taken from the "Child tags" tables of the Objects documented in this
+ * document. In a path each key value pair has to be separated by one space character. e.g. getting
+ * the handle to the previously created @ref ua_protocol_iso_tp of that @ref ua_channel :
+ * ~~~.c
+ * BL_HANDLE protocol_handle;
+ * BLC_createHandle(channel_handle, "protocol=my_dtl", &protocol_handle);
+ * ~~~
+ *
+ * ### Getters
+ *  To read values of properties use @ref BLC_getSignedNumber, @ref BLC_getUnsignedNumber or @ref
+ * BLC_getBinary functions. The __path__ parameter has to end with the tag identifying the property
+ * to read. Valid tags can be taken from the "Property tags" tables of the Objects documented in
+ * this document. e.g. reading the requestFrameID from a @ref ua_service_iso_tp :
+ * ~~~.c
+ * uint64_t requestFrameID;
+ * BLC_getUnsignedNumber(service_handle, "req_frame_id", &requestFrameID);
+ * ~~~
+ *
+ * ### Setters
+ *  To store values of properties use @ref BLC_setSignedNumber, @ref BLC_setUnsignedNumber, @ref
+ * BLC_setBinary or @ref BLC_setCallback functions. The __path__ parameter has to end with the tag
+ * identifying the property to store. Valid tags can be taken from the "Property tags" tables of the
+ * Objects documented in this document. e.g. setting the requestFrameID of a @ref ua_service_iso_tp
+ * to 59 :
+ * ~~~.c
+ * BLC_setUnsignedNumber(service_handle, "req_frame_id", 59);
+ * ~~~
+ *
+ * ### Execution of Methods
+ *  To execute an object's method use @ref BLC_execute or @ref BLC_execute_async functions. In the
+ * path variable only the identifying tag is required. Valid tags can be taken from the "Method
+ * tags" tables of the Objects documented in this document. Functions might have parameters. Those
+ * can be specified by appending key value pairs to the path in the same manner as when creating new
+ * objects. The order of the parameters is not relevant. In some cases a synchronous call is not
+ * applicable, in these cases use @ref BLC_execute_async to execute the method in a dedicated
+ * thread. e.g. executing a @ref ua_service_iso_tp :
+ * ~~~.c
+ * BLC_execute(service_handle, "execute");
+ * ~~~
