Method

How it works

Four steps, the same every time. The point is that a reader can check each one.

1. A report or a datasetSomething already published: a survey of 100 women platform workers, a labour-hours estimate, a union's letter with a demand in it. We read the whole thing, not the press release, and we quote it by page.
2. One day, one composite character, one targetA day is the unit people can feel; a year is a statistic. The character combines what the data says into one person with a name, a route and a number they need by night. Reported facts, calculated results and illustrative details are labelled separately on every story page.
3. Every permitted sequence of choices, run through the same model the player usesThree choices an hour for twelve hours is 3¹² = 531,441 possible days; for fifteen hours, 3¹⁵ = 14,348,907. We run all of them and record the best outcome under each constraint: never leaving the coping zone, never reaching exhaustion. That is how a results page can say "no schedule reaches the target safely" as a property of the model rather than a script. Each story states its model version and the counts are reproducible from the published constants.
4. Replay the day under a different policy, and see what changes in the modelTwo paid breaks. A relief payment that arrives in a week instead of "under verification". The same day, the same choices, one rule changed. The comparison shows what the policy does inside the model. It does not show what the policy would do in the world; that is the organisation's argument to make, with its own evidence.

What the model is, and isn't

The body-heat score is a simple running number: it rises with temperature and effort, falls with shade and water, and crosses fixed thresholds into stress, exhaustion and danger. It is tuned so a full day lands where workers report, and it is built for play. It is not WBGT, not a heat index, and not a physiological model; it does not use humidity, radiant heat, clothing or acclimatisation. If an organisation's public-health advisers want a story on a recognised footing, we build to their guidance and say so on the page. We would rather ship a model someone qualified has signed off than defend our own.

Money in the stories is usually illustrative: pay per order, travel cost, the day's target. The percentages and counts are usually reported. Every story page separates the two.

What you get

A single web page, typically under 400 KB, that opens from a WhatsApp link on a basic Android phone. No app, no sign-up, no tracking beyond a cookie-free page count. It can be hosted on your domain or ours, embedded in an article, or opened from a QR code at a meeting. The methodology is written up in plain language so it can be forwarded to a reviewer.
