Verify Artem Tesla Grid Services retry-storm fix/regression risk

Artem asked in Slack thread 1779431430.431259 on 2026-05-22 to verify his Tesla Grid Services retry-storm fix actually fixed the 413 retry storm and did not create new problems. Prior assistant turns failed before content, so this needs immediate follow-up: inspect the fix/PR or main state, run targeted tests/static checks, and check relevant prod logs/Datadog if available. Distinguish provider token/scope 401 issues from retry-storm behavior. Report evidence back in-thread.
