A CONCEPT · PROJECTED FROM THE VINDEX KNOWLEDGE GRAPH
STATE PRECISION & GEOMETRY
declared, or the planner refuses
A recurrence must be held at some precision, and the planner does not get to pick one: state geometry comes from the plan, and state precision is a declared fact or a named refusal.
Qwen3.8 declares float32 state against a bf16 model — the checkpoint stating its recurrence is precision-sensitive in a way its bulk weights are not, because error in a state that feeds itself forward compounds. KDA and Mamba2 declare no state dtype, so continuation planning refuses to choose one rather than silently running the recurrence at the bulk precision. The refusal is the feature: an undeclared fact never becomes an executor's guess.
