Sample Cohort — Twenty Synthetic Children

Reproducible verification artifact. Generated by walking a single deterministic cohort (seed=42, size=500) and picking the first child matching each of twenty archetypal predicates. Re-runnable via:

pnpm synth:samples > docs/docs/synthetic-personas/sample-cohort.md

Same seed produces bit-identical results — anything below this line is reproducible.

What this page proves: the generator emits realistic, internally-coherent pediatric Family + Guardian + Patient personas across the full breadth of US peds-practice variation, with coemission rules (severe peanut → Epi-pen, T1D → insulin, ADHD → CII Rx) firing correctly and with archetype-specific constraints attached.

What it doesn't prove: clinical accuracy of any individual numeric value (growth percentiles use a coarse approximation, not CDC LMS curves; vaccine schedule dates are illustrative). For clinical-grade fidelity, see the implementation plan for SP5 (timeline derivation) and SP6 (LLM narrative texture) follow-on work.

Determinism check

Same seed + same family index produces identical output across calls. The generator forbids Math.random() and uses mulberry32 keyed by (cohortSeed + familyIndex × 2654435761). Distribution invariants are tested in generate.test.tspnpm vitest run scripts/synthetic-personas once vitest is wired into the workspace.
