Checkpoint strength
Understand checkpoint strength in ordinary language first. The exact definition and manuscript source follow below.
In ordinary words
The authority a trace deserves given provenance, independent convergence, contestability, route of appeal, and fit with the consequence it is asked to carry.
What this does not prove
Use this as a handle for noticing a pattern, not as a label that settles a person or event.
The internal register includes remembered scenes, images, phrases, emotional associations, learned concepts, and the private continuity by which a person recognizes a life as their own.
Jonah's memory of the van is not a video stored behind the eyes. It is a reconstruction from perception, attention, later information, bodily state, and the questions asked during recall. He may remember the bicycle light because it matters to whether Priya should have seen him. He may become more certain about sequence after repeatedly telling the story. A phrase from the officer, "You came out of nowhere," may later appear inside the memory as if it belonged to the event itself.
The internal register is uniquely rich in lived significance. It can preserve fear, intention, surprise, and the way a moment reorganized the self. It can also confuse source, sequence, frequency, and confidence.
Its ownership appears simple because the memory is inside the person. In practice, other people can load, cue, reward, shame, and challenge it. Interview methods matter. Family stories matter. Repetition matters. A memory can be private and socially shaped.
The characteristic error of the internal register is not merely forgetting. It is coherence. The mind tends to return a scene that makes sense under the present query. That coherence is often useful and often accurate enough for life. It becomes dangerous when fluency is mistaken for direct access to the event.
The somatic register includes learned bodily patterns, conditioned responses, procedural habits, pain, posture, arousal, and other residues through which prior experience changes present readiness. It is not a filing cabinet in the skin.
Jonah's wrist injury is physical evidence of impact, but it does not identify the traffic signal. His startle at a turning van is a learned response, but it does not prove that every future van is dangerous. His body may preserve the speed of the event more faithfully than his verbal sequence. It may also generalize the alarm to harmless situations.
