- Added `leaked-thinking-stream.ts` whose `wrapLeakedThinkingStream`/`LeakedThinkingProjector` re-projects any provider stream, splitting leaked ```thinking`/`<think>` fences out of the visible-text channel into structured thinking blocks live while preserving text/thinking/tool signatures.
- Wrapped the shared `withProviderInFlightLimit` dispatch (both the unlimited and queued paths) and the standalone GitLab Duo path in `stream.ts` so healing covers every provider exit idempotently.
- Reworked `google-gemini-cli.ts` visible-text emission onto `StreamMarkupHealing` with `feedVisibleText`/`flushVisibleText` and explicit block bookkeeping, lifting leaked Gemini fences ahead of native tool calls.
- Added `leaked-thinking-stream` coverage and a gemini-cli healing case, and updated `stream-auth-retry`/`google-gemini-cli-alignment` expectations for the healed event sequence and dropped empty-text residue.
- Recorded the changelog `### Fixed` entry (whose run also carries the adjacent Codex `all_turns` line).
