 ### Changed
 
+- Enhanced cross-model reasoning recovery to support additional thinking dialects and leakage patterns
+
 - Demote cross-vendor reasoning to plain text when the target does not natively support it
 - Refine cross-model reasoning preservation to prevent leaking inert context into structured fields
 - Rendered demoted cross-model reasoning blocks in the target model's canonical thinking dialect
 - Improved reliability of AI model responses by implementing automatic retry logic for detected thinking-loop stalls
 - Changed cross-provider/cross-model thinking demotion to render the prior turn's reasoning in the target model's canonical inline thinking dialect (a ```` ```thinking ```` fence for Gemini, `<think>`/`<thinking>` tags for others) instead of bare prose, with a neutral `<think>` fallback for control-token dialects (Harmony, Gemma) so chat-template tokens never leak into history. Replaying it as a native `thought` block was ruled out: end-to-end testing against Gemini 3 confirmed an unsigned `thought` part is schema-accepted but silently discarded — neither recalled nor influencing generation.
+- Broadened the leaked-thinking stream healer (`StreamMarkupHealing`'s `thinking` pattern) to recover reasoning emitted in any dialect's canonical idiom — Gemini's ` ```thinking ` fence, Gemma's `<|channel>thought` channel, Harmony's `analysis` message, and `<scratchpad>` — not just `<think>`/`<thinking>` tags, so leaked chain-of-thought is routed to thinking events for every dialect instead of rendered as raw markup
