A navigational map of the sensor landscape. Each row is a
sensor family — a question
you're asking about the system. Each column is a stage of the software
lifecycle — when the signal becomes available, from authoring
the code on the left to observing real-world outcomes on the right.
For the narrative version of how evidence accumulates, see the
confidence stack.
Use the atlas to orient yourself. What question are you
asking? Find the row. When can you afford to learn the
answer? Find the column. Empty cells are questions nobody
instrumented at that stage yet.
Sensor families are not a stack — evidence from one family routinely
depends on another family having done its job. Arrows point from the
family that leans to the family it leans on, labelled with a sensor
that carries the connection. Hover a node to isolate its
neighborhood. Drawn from the cross-references inside the catalog
entries themselves; only the strongest links are shown.
