v6.1.9

v6.1.9 - 2026-05-11

Fixed

• Legacy Codex selectors such as gpt-5.2-codex, gpt-5.3-codex, and Spark now recover from entitlement-gated gpt-5-codex responses by falling back through the GPT-5.4 family.
• Default fallback now continues from gpt-5.4 to gpt-5.4-mini and gpt-5.4-nano only when the chain started from gpt-5.5 or canonical gpt-5-codex, preserving strict behavior for direct GPT-5.4 selections.
• Unsupported-model troubleshooting and configuration docs now document the canonical Codex fallback path and the CODEX_AUTH_DISABLE_CODEX_AUTO_FALLBACK=1 opt-out.
• Current dependency security alert follow-ups are resolved.
