HRR as a rescue layer for recurring failure sectors

HRR in TightLoop is used as a structured residual-correction idea: bind context and recurring error patterns into sectors that can be recognized again.

The language around HRR can easily become too abstract. The product interpretation is simpler. Some failures repeat in recognizable contexts. The controller may not need a new full model for every case; it may need a compact way to remember that a certain residual pattern belongs to a known correction sector.

That idea appears across the product lines. In grip control, HRR helps route contact states and packet memory. In Sentinel, sector memory contributes to warning persistence and context. In motion assist, it helps keep the residual layer from acting as a generic smoother.

The correct evaluation is not whether HRR sounds elegant. It is whether a system with HRR reduces residual error, false positives, missed warnings, or tail events under the same replay.

That makes HRR a rescue layer in the practical sense: it targets the recurring misses that remain near the final command or final alert.
