These signals appear across JITAI, affective computing, and learning analytics research. They are not invented for this framework. The contribution is organising established signals into a coherent taxonomy with explicit ABSD layer mappings.
Important
These mappings represent base associations - the most common signal-to-state relationship in the absence of countervailing context. A 30-second pause before a complex financial trade may indicate deliberate prudence, not confusion. Always apply contextual modifiers before acting on any single signal.

Watch a real signal traced from Action to Drive.
The Signal Tracer takes a specific behavioural event in your domain and shows the full inference chain — what each layer captures, what it misses, and where ABSD continues beyond where current systems stop.
