+## [1.26.2] — 2026-09-09
+
+### Fixed
+- **Character-Sheet Generation Could Stop on HTTP 405.** If an OpenAI-compatible LLM gateway rejects the configured
+  version-prefixed chat route (`/v1/chat/completions`) with 405, character-sheet extraction now retries the gateway's
+  root chat route (`/chat/completions`). This applies to both the live stream and its non-streaming fallback, so an
+  otherwise healthy gateway no longer drops the current passage.
