## Statements (checkable)
0. A Google Cloud project with an OAuth consent screen for an external user type and publishing status "Testing" is issued refresh tokens expiring in 7 days, unless the only scopes requested are a subset of name, email address and user profile.  [✓0 ✗0]
1. Refresh tokens also stop working when unused for six months, when the user revokes access, when the user changes password and the token has Gmail scopes, or when the 100-refresh-tokens-per-account-per-client limit evicts the oldest token.  [✓0 ✗0]

## Fix
```text
Publish the OAuth app (move to "In production", with verification if sensitive scopes are used) so tokens do not expire weekly; otherwise a human must re-consent every 7 days. Handle invalid_grant by re-running the consent flow, not by retrying.
```
