Abstract
Unsuccessful ageing. Contextual factors influence modifiable and non-modifiable determinants of health. Formative behaviours include diet, exercise, sleep, socialization, and avoidance of excess stress, smoking, alcohol, and drugs. Access to healthcare is instrumental to inform behavioural change and prevent the onset or progression of disease. Accumulation of diseases, as well as subclinical impairments in multiorgan functionality, erode the body’s allostatic and intrinsic capacities. Allostatic capacity relates to the restoration of physiological homeostasis in response to stressors and it is mediated by immune, endocrine, autonomic, hepato-renal, and cardiovascular systems. Intrinsic capacity relates to the preservation of autonomous functioning and it is mediated by locomotive, energetic, cognitive, psychological, and sensory faculties. If these faculties fall below a critical threshold, and they cannot be enabled by assistive technologies (e.g. a walking aid), then one becomes dependent for activities of daily living. Institutionalization, defined as living in an assisted care facility or hospital, is modelled as the end result of unsuccessful ageing in the absence of available caregivers to help perform activities within the home setting. Frailty has been operationally defined as narrowly as locomotive intrinsic incapacity (e.g. gait speed) or as broadly as summated intrinsic incapacities, allostatic load, upstream diseases, and downstream disabilities (e.g. frailty index).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
