pho-registered-audit

Solve "Public Health Observatory" (PHO) registered algorithmic-audit tasks: a business prompt plus a formal analysis_request.json (protocol: cohorts, statistical modules, seeds/grids, robustness gates, decision rule) and a strict answer_template.json (output contract), backed by a read-only public-health data portal. Use this whenever a task hands you an analysis_request.json / answer_template.json pair that references a health-observatory Web portal and asks for one JSON object of resolved releases, cohorts, multi-module diagnostics, and a controlled decision. Covers state / county / country geographies and the recurring six-module audit anatomy (fixed-effects & jackknife, nested ridge / elastic-net CV, wild cluster bootstrap-t, grouped conformal, trajectory PCA + k-means + ARI, source/year perturbation & Shapley).

# Public Health Observatory — registered algorithmic-audit playbook

## 1. Recognise the task family

Every task in this family gives you three inputs (names may vary slightly):

- **`prompt.txt`** — business framing (who is deciding what). It is context only; the
  *authoritative* spec is the JSON payloads.
- **`payloads/analysis_request.json`** — the registered protocol. It declares the
  geography scope, analysis years / reference year, outcome / exposure / adjustment
  variables, evidence & cohort definitions, an ordered set of **audit modules**
  (each with its exact method name, cohort, feature order, seeds, grids,
  checkpoints), the **robustness gates**, and the **decision rule**.
- **`payloads/answer_template.json`** — the output contract: required top-level keys,
