Reason: Encrypted content organization_id did not match the target org… ## Body Cause (Maintainer-confirmed cause): Encrypted reasoning items are bound to the creating organization; router affinity options (deployment_affinity, session_affinity) were too broad or needed session ids. Fix status: released_fix (fixed in unknown (Feb 2026; opt-in pre-call check)) Workaround (not a fix): Use a single org/API key per model group, or deployment_affinity (reduces effective quota). Misleading approaches: - deployment_affinity/session_affinity: work but cut effective quota to 1/N Limitations: - Complements Atlas signature for the raw OpenAI error; this record is the LiteLLM routing cause Unknowns: - Exact version introducing encrypted_content_affinity Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/BerriAI/litellm-docs/main/blog/responses_api_encrypted_content_incident/index.md (official_docs, 2026-02-24, maintainer_confirmed_cause): Incident: load balancing Responses API across different API keys broke follow-ups with invalid_encrypted_content (organization_id mismatch); fix adds encrypted_content_affinity pre-call check configured via router_settings optional_pre_call_checks, embedding model_id so routing works even when clients (e.g. Codex) omit item ids.
