The previous version described the pre-refactor flow only — no
hardware-suite conftest, no helper layer, no PSU resolver, no
settle-then-validate pattern, no junit_family note. Rewritten so it
reflects the current architecture without losing the original
sequence-diagram + text-flow shape.
What's new in the doc:
- Two-layer fixture model (project-wide vs hardware-suite) called
out at the top.
- Mermaid sequence diagram now shows the session-scoped autouse PSU
power-up, the helper layer (FrameIO / AlmTester / psu_helpers),
and the safe-off-on-close at session teardown.
- Text-flow split into PROJECT-WIDE / HARDWARE-SUITE / TEST-BODIES
sections; describes resolve_port's fallback chain and the
settle-then-validate behaviour of apply_voltage_and_settle.
- "Where information is fetched from" gains the LDF, rgb_to_pwm,
and per-machine PSU override paths.
- "Key components" split into project-wide / hardware-suite, listing
every helper and template file.
- Edge cases gain PSU-side entries: cross-platform port resolution,
the must-not list (no set_output(False), no close()),
apply_voltage_and_settle's timeout behaviour, and the
junit_family=legacy requirement for record_property round-trips.

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/.

The MUM (Melexis Universal Master) adapter is the current default; the
BabyLIN SDK adapter is retained only for backward compatibility with
existing rigs.
Code:
- Emit DeprecationWarning when BabyLinInterface is instantiated and
when tests/conftest.py routes interface.type=='babylin' to it.
- Update module/class docstrings in ecu_framework/{__init__,config,
lin/__init__,lin/babylin}.py to label BabyLIN-specific fields and
paths as deprecated.
Config / scripts / pytest:
- pytest.ini: relabel the babylin marker as deprecated.
- config/{babylin.example,examples,test_config}.yaml: add deprecation
banners and field comments.
- scripts/99-babylin.rules and scripts/pi_install.sh: annotate the
udev-rule install block as legacy-only.
Documentation:
- TESTING_FRAMEWORK_GUIDE.md, docs/08_babylin_internals.md, and
vendor/README.md: prepend explicit "DEPRECATED" banners.
- docs/{README,01,02,04,05,07,09,10,12,13,14,15,18,DEVELOPER_COMMIT_
GUIDE}.md: relabel "legacy" to "deprecated" where babylin is
mentioned, present MUM as the primary path, and steer new work
toward the MUM examples.
No tests, configs, or modules were deleted; existing BabyLIN setups
keep working but now produce a clear DeprecationWarning at runtime.
