# Credit Estimator

"When do I run out?" Answered in your own dashboard.

Embeddable, provider-neutral credit forecasting. Burndown runway for
sellers, pre-commit planning for buyers, from data your app already has. Six
npm packages, MIT licensed, works with or without Tanso.

## Two questions, one core

- **Forecast, for sellers. When does this customer run out?** Feed it observed
  daily usage and a balance. The deterministic core projects the ending
  balance, depletion risk, and shortfall across explicit low, base, and high
  scenarios, and the React package renders it inside your dashboard.
- **Plan, for buyers. How many credits should I buy?** No history needed.
  Per-metric usage estimates times credit weights, scaled across scenarios
  and compared against a candidate allocation. Everything is an explicit
  input. It never invents weights, prices, or predictions.

## Packages

Install the two most people start with:

    npm install @tansohq/credit-forecast-core @tansohq/credit-burndown-react

- `@tansohq/credit-forecast-schema`. Provider-neutral Zod schemas and
  TypeScript contracts.
- `@tansohq/credit-forecast-core`. Deterministic burndown and planning
  calculations, browser and Node.js.
- `@tansohq/credit-burndown-react`. Controlled, accessible React components.
- `@tansohq/credit-forecast-json`. Deterministic JSON import and export.
- `@tansohq/credit-forecast-csv`. Portable multi-file CSV import and export.
- `@tansohq/credit-forecast-tanso`. Optional Tanso snapshot-to-neutral
  mapping.

## Design constraints

The core reads no clock, network, or product state; inputs are explicit and
results carry full calculation traces. It is read-only by design. It never
owns wallets, ledgers, or payments, and it never writes back to your billing
system. An optional adapter maps a Tanso snapshot into the same neutral
input any other host supplies.
