The session analysis ranked its weakest topics by primary category only,
while the Analysis page asked the same question three ways and rolled
answers up the category tree. Two sets of rules for "where does this
question belong" is two pages that can disagree about a learner and
neither able to explain why.
So the rules moved to services/knowledge_groups.py: ancestor roll-up,
article reached through its category, organ system reached through the
symptom keyword. study_tools now asks that service instead of building
the lookups inline, and GET /attempts/{id}/recommendations gives one
session the same Articles / Disciplines / Systems switch. Grouping is its
own call, so changing it does not re-read the question table and the peer
statistics beside it. A running exam ranks nothing — marking it there
would answer the question the exam is asking.
The ungrouped `recommendations` key is gone from the analysis payload
along with the code that built it.
And the document page had no way back. It is reached from the Tools
workbench, which by design has no menu of its own, so leaving it meant
the browser button. It opens onto Tools now, as Tools opens onto
Settings.
