1//! A test workspace's billing, wiped: `admin_reset_billing`.
2//!
3//! While billing runs on Stripe's test key, staff can return a workspace
4//! used for testing to how a new customer starts: no ledger, balance,
5//! plan, limits, trial grant, invoices, holds, signals or cost rows. Its
6//! workspace, members and repositories are not billing's and stay. Never
7//! with a live Stripe key, never for a comped workspace, and never for one
8//! an enterprise pays for. The reset itself is kept in the audit log, and
9//! g1t's own counts of the workspace's git operations stay: they are what
10//! Cloudflare's bill is compared with, not what the workspace owes.
11//!
12//! What the wiped usage cost g1t is kept too (`reset_costs`): the model
13//! calls and Cloudflare usage still happened, and AI Gateway and the bill
14//! still show them. The costs run counts that as given away on purpose
15//! ("testing resets"), so it is neither drift nor a leak.
