"""Activity layer of the content graph: who did what, on which topic, with which tool.
|
|
|
|
Built offline (``python -m tools.knowledge.activities build``) from the published
|
|
content checkpoint, never while answering. It needs the configured LLM and the
|
|
consent to send profile units to that provider, like ``tools.knowledge.build``.
|
|
|
|
Every activity keeps its source unit. Topic and tool phrases are verified,
|
|
contiguous substrings of that unit; the student, work, phase and dates come
|
|
from the unit itself, so the model can neither invent nor move them. The model
|
|
also names each phrase with a short canonical English name. Concepts are then
|
|
unified automatically: equal canonical names, acronyms of multiword names,
|
|
one literal phrase named in several ways and close names (embedding candidates
|
|
that the model confirms as the same concept) form one concept group.
|
|
|
|
Answering "who did X" is then a lookup in this graph: the topic of the question
|
|
is resolved to concept groups, the groups to activities and the activities to
|
|
their verbatim source units. No model judges records during the question.
