+--------------------
+The workbook references debugger-only firmware variables (``u8AnmMode``,
+``strAnmState.bActive``, ``strAnmState.u16TimeUnits``, ``strAnmState.prevR/G/B/I``).
+These cannot be observed over the LIN bus, so each test is rewritten to
+exercise the **LIN-observable** behaviour that those variables produce:
+
+- ``u8AnmMode`` — observed indirectly via ALMLEDState transitions:
+  Mode 0 reaches LED_ON without passing through ANIMATING; Modes 1/2 with
+  ``AmbLightDuration > 0`` do pass through ANIMATING.
+- ``strAnmState.bActive`` — equals ``ALMLEDState == LED_ANIMATING``.
+- ``strAnmState.u16TimeUnits`` — measurable as the duration of the
+  ANIMATING window, in seconds, via :meth:`AlmTester.measure_animating_window`.
+- ``strAnmState.prevR/G/B/I`` — the *final* RGBI is verified via
+  PWM_wo_Comp; per-tick intermediates are not LIN-observable and are
+  documented as such.
+
+Marker: ``ANM`` — see ``pytest.ini``.

+Translation strategy
+--------------------
+The COM tests are about LIN communication: NAD addressing, LDF/baudrate,
+ALM_Req_A signal layout, LID-range targeting, and frame periodicity.
+
+- ``Watch color table`` (firmware lookup) is exercised end-to-end:
+  drive a known RGB at full intensity and verify ``PWM_Frame`` matches the
+  ``rgb_to_pwm.compute_pwm`` calculator (which encodes the same color
+  table).
+- NAD: read ``ALM_Status.ALMNadNo`` and confirm it falls inside the
+  valid NAD range declared by the LDF.
+- Baudrate: physical-layer; not measurable from inside the test runner
+  (requires a scope) → the step is recorded for traceability and skipped.
+- ``ALM_Req_A`` byte-mapping: send a frame with distinctive RGB+I values
+  and confirm the ECU's response (LED reaches ON, PWM matches) — that
+  proves byte-level interpretation end-to-end.
+- LID-range flag: drive a frame inside vs. outside the node's range and
+  observe whether the LED reacts.
+- 5 ms periodicity: a master-side LIN-master scheduling property that
+  the slave does not echo back; documented as not directly observable.

+- ``ALM_Req_B`` (a second request frame for LED-on/-off commit)

+The current LDF uses a different addressing scheme: each ALM_Node has a

+inside ``ALM_Req_A``. Until the LDF is updated to expose the workbook's
+signals (or the workbook is updated to match the deployed LDF), these

+Each test below performs a **real LDF probe** for the missing signals.

+"""POC — data-driven ALM_Req_A tests via an :class:`AlmCase` dataclass.
+
+A single test function (:func:`test_alm`) is parametrized over a list
+of :class:`AlmCase` instances. Each instance carries:
+
+  - identity & reporting metadata (id, title, description, requirements,
+    severity, story, tags)
+  - inputs to ``ALM_Req_A`` (RGB, intensity, mode, update, duration,
+    LID range)
+  - expected outcome (state to reach OR "must not transition", PWM-check
+    flags, timeouts)
+  - a ``run(fio, alm, rp)`` method that executes the case end-to-end
+
+Compared with :mod:`test_mum_alm_animation` (one ``def`` per case):
+
+  - **Adding a new case is one Python literal**, not a new function +
+    duplicated boilerplate.
+  - The shape of every case is *visible* on the page — easy to scan
+    a coverage matrix at a glance.
+  - Cross-cutting changes (e.g. "all cases should also assert the
+    measured NTC is plausible") happen in one place, the runner.
+  - Trade-off: less freedom for a single case to do something
+    one-of-a-kind. When a case needs custom behaviour the dataclass
+    can be subclassed, or that case stays as a hand-written
+    ``def test_xyz`` in the original file.
+
+The fixtures and the docstring-derived metadata mirror what
+``test_mum_alm_animation.py`` does — this is purely a re-arrangement
+of the same domain logic. Per-case identity/severity attributes are
+recorded via ``rp(...)`` so they show up in the JUnit XML and the
+HTML report's metadata columns.
