OpenRouter relays OpenAI's "this user has been blocked for a previous
policy violation" as HTTP 200 + an SSE error event. The SDK raises a
status-less APIError that no classifier rule matched, so it landed in
the retryable `unknown` bucket: every retry was re-sent (3 streamed
requests by default), a configured fallback only engaged after the
ladder, and the user was told the provider "looks temporarily
unavailable. Wait a minute and send /retry".
- error_classifier: match the ban phrase status-agnostically in
_provider_special_cases -> provider_policy_blocked (non-retryable,
fallback, no credential rotation: every key on a banned account is
banned; a 403 variant is not a bad key).
- turn_failure_copy: provider_policy_blocked chat copy now covers an
account block as well as data/privacy settings; add its cause gloss
so cron and subagent notices explain it instead of printing raw text.
- cron: provider_policy_blocked action (retrying won't help; pin another
model).
- docs: FAQ entry for the reply; auto-recovery ladder exclusion list.
