Choosing a reasoning pattern & hybrids (LATS)

A decision framework rather than a single technique. The same agent can be built
four different ways, each with a different failure mode and cost profile. Students
learn to choose along three axes — token cost, adaptability, and inspectability —
and to recognise hybrids, such as wrapping a Tree-of-Thoughts search around a
ReAct or ReWOO core (the approach behind Language Agent Tree Search).
