 Each tendency defines the behavior of the signal over a specific time interval. You can chain multiple tendencies together to create complex waveforms.
 
-If ``type`` is omitted it is inferred from the entry's keys: ``ref`` → :ref:`import <import-tendency>`, ``to`` → linear, ``time`` → :ref:`piecewise <piecewise-linear-tendency>`, ``value`` → constant; anything else defaults to ``linear`` (so a ``from``-only, ``rate``-only, or bare segment is still a linear ramp). Tendencies with no distinguishing key -- the periodic shapes, ``smooth``, and a value-less ``constant`` -- must name their ``type`` explicitly.

-Takes its values from an external entry in :ref:`globals.imports <global_properties>` instead of an analytic shape, resampled onto the export time base. By default it reads the waveform's own DD path.

-*Type:* ``import`` (inferred when ``ref`` is present)
-
-Parameters
-----------
-*   ``ref``: Entry in ``globals.imports`` to read from.
-*   ``path``: DD path to read. Defaults to the waveform's own path.
-*   ``time_offset``: Offset added to the export time when sampling. Defaults to ``0``.
-*   ``interp``: Resampling mode: ``closest`` (default), ``linear`` or ``previous``.

-Wildcards expand against the source: a trailing ``*`` imports a whole subtree (``<ids>/*`` copies a whole IDS), and a ``(*)`` index wildcard iterates every element of an array of structure -- several may be combined, e.g. every ion of every source. An overlay may list several sources, applied in order:
-
-.. code-block:: yaml
-
-    core_sources/source(*)/profiles_1d/ion(*)/z_ion:
-      - {ref: scenario}
-
-    ec_launchers/*:        # whole-IDS overlay; sources stack
-      - {ref: machine}
-      - {ref: scenario}
-
-**Precedence.** Where imports or explicit waveforms write the same node, the most specific wins regardless of order: ``<ids>/*`` < subtree ``.../*`` < explicit leaf. Equal specificity falls back to listing order (last wins).
-
-Non-0D imports (a profile, a wildcard subtree) own the whole waveform. Only **0D (scalar)** imports combine with analytic segments, each filling its ``[start, end]`` window:
-

-    equilibrium/time_slice/global_quantities/ip:
