 ### 🔧 Bug Fixes
 
 - **fix(translator):** every Gemini/Vertex `functionDeclaration.parameters` is now coerced to an OBJECT-typed schema before cleaning. Clients like GitHub Copilot send some tools (e.g. `terminal_last_command`) whose `parameters` is present but lacks a top-level `type: "object"` (just `{ properties }`, a scalar type, or `{}`); these slipped through `buildGeminiTools`' `params || default` guard and Vertex rejected them with `[400] ... functionDeclaration parameters schema should be of type OBJECT`. Hardens every OpenAI→Gemini tool request (Vertex / antigravity / agy / gemini). (#3357 — thanks @nullbytef0x)
+- **fix(gemini):** normalize Gemini/Antigravity textual `[Tool call: ...]` markers — stop suppressing **false positives** (legitimate assistant prose that merely mentions `[Tool call: terminal]`, e.g. in backticks, is preserved instead of being swallowed) and correctly buffer markers **split across streaming chunks** (`[Tool` + ` call: terminal]` + `Arguments: {...}`), flushing the text when it turns out not to be a tool call. Dedups the parsing/validation into a shared `open-sse/utils/textualToolCall.ts` (new `isValidToolCallHeaderPrefix`) and adds `gemini-2.5-flash`/`gemini-3.5-flash-low` model specs. ([#3358](https://github.com/diegosouzapw/OmniRoute/pull/3358) — thanks @Ardem2025 / @diegosouzapw)
 - **fix(electron):** clicking "Exit" (or applying an update) now terminates the **whole** server process tree, not just the direct child. The embedded server runs as `omniroute.exe`-as-node (`ELECTRON_RUN_AS_NODE`) and spawns grandchildren (embedded services, MITM proxy, tunnels); on Windows `ChildProcess.kill()` only terminates the direct child, so survivors kept `omniroute.exe` locked — the process "hung in memory" after Exit and updates failed with "file in use". New `killProcessTree()` helper uses `taskkill /PID <pid> /T /F` on Windows (signal-based on POSIX); wired into `stopNextServer`, the `waitForServerExit` force-kill, and `installUpdate`. (#3347 — thanks @Flexible78)
 - **fix(proxy):** proxy auto-selection is now **opt-in** (new `PROXY_AUTO_SELECT_ENABLED` flag, default off). Previously a single proxy in the registry silently became a global fallback for **all** provider connections (the Step-11 fallback listed every registry proxy, ignoring assignments and per-connection `proxy_enabled`). It now no-ops unless the operator enables the flag. (#3332 — thanks @hertznsk)
 - **fix(cli):** write the OpenCode config to `~/.config/opencode/opencode.json` on **all** platforms — on Windows OmniRoute wrote to `%APPDATA%\opencode\` but OpenCode reads from `%USERPROFILE%\.config\opencode\` (XDG), so dashboard-saved config silently had no effect. (#3330 — thanks @abdulkadirozyurt)
