Direzione di ricerca

Start by reading the open pull request #903, which is already working on this issue. The issue describes the v2 household functions, version manifest, release validation, and image checks, but does not name specific files or tests. Done means both country functions, manifest and validation changes, and the pre-merge image check meet the listed behavior.

Descrizione

What

Add Modal functions that calculate one household under several policies in one call, for the US and the UK, in the versioned v2 Modal application:

  • A versioned household contract: a household in the Public API's situation shape, with optional axes; one to ten policies per request, so a baseline and its reform are calculated together; a schema version; the PolicyEngine.py bundle the caller expects; an optional SPM selection; and an option to add every missing variable, as the Public API's /calculate-full route does. The result carries each policy's calculated household, warnings and SPM receipt, the applied SPM selection and the bundle provenance, or a typed failure.
  • calculate_household_us and calculate_household_uk, which reproduce the Public API's household calculation (input preparation, unrecognized-input errors and their order, deprecated-input warnings, value formatting, SPM handling) and run in their own image with no datasets and no secrets, sized for large households with axes.
  • Schema version 2 of the v2 version manifest, which records for each country whether it can run economy reports and which function calculates its households. The comparison adapter gives the report coordinator only countries marked economy-capable.
  • Release validation that calls each household function with a small household before the manifest names it.
  • The pre-merge image check builds every v2 image (report coordinator, country workers, household functions) and imports their entry points.

Why

Household calculations run inside the Public API's web process today. Moving them to Modal lets the Simulation Entrypoint calculate and store households the same way it handles economy reports, and computes a baseline and its reform in a single call. Nothing calls these functions yet: they are deployed but unused until the Simulation Entrypoint gains household routes.
