"'Slept badly and the knee was stiff' is not one thing to file. It is a measurement and a symptom, from one breath."
The Reading Types
The typed layer draws from a small vocabulary of reading types: symptom, workout, intake, medication, measurement, medical-record, meal — plus note as the honest catch-all when the prose is real but fits none of the others. This is not a menu Dad picks from; it is the shape Pippa maps his words onto, after the fact. The vocabulary is deliberately small and stable, because a controlled set is what makes months of crumbs comparable — but it lives in interpretation, not in a capture form.
One Crumb, Several Readings
Prose does not respect one-topic-per-sentence, so a single crumb can carry several readings. "Slept badly and the knee was stiff" yields a measurement/sleep reading and a symptom reading at once; "took the new supplement, felt a bit nauseous after lunch" can yield intake, meal, and symptom. The reading names only what the prose actually supports — a site and quality for a symptom, a value and unit for a measurement, a substance statement for a medication — and never invents a field the words did not earn.
The Rubric Knows Dad
The reading rubric is not generic; it carries a few standing facts about Dad so it never contradicts them. A substance he never touches has no intake sub-field at all and no correlation branch that assumes otherwise — absolute, not a preference; there is nothing to reduce. A long-known pattern makes its symptom class the expected primary class, never an edge case. What the facts are stays in the vault; what the rubric does with them is the lesson — the typed layer reads his body the way someone who knows him would. Which is, again, the whole point.
