/**

* Experiment 44 — Assessor Against Unclear Starting Point
|
||||
*
|

* One deliberately vague investigation with several competing unknowns,
|
||||
* no resolved evidence, and no clear decision target. Tests whether the
|

* existing assessor produces any signal that justifies Clarify.
|

*
|

* No production code changes. No existing fixture modification.
