What probably matters to youSection of the release
What
When a background agent run stops, its stop reason is now mapped to one of auth, billing, context limit or model unavailable, each with a user-facing label and error code, so a failed run says why it failed. A "credit balance too low" stop is reported as a billing problem.
Details
The auth category is deliberately suppressed for remote sessions, where re-authenticating locally would not help.
Evidence
credit balance too low
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
