### 🐛 Bug Fixes

- **fix(mitm):** Compile MITM utilities as NodeNext ESM during prepublish, copy the CommonJS MITM server into the standalone artifact, and resolve MITM data paths without relying on Next.js aliases in packaged runtime.
- **fix(build):** Move the local `.tmp/wine32` Wine prefix out of the isolated Next.js build path so Windows Electron packaging artifacts cannot trigger `EACCES` scans during Node 24 builds.
- **fix(build):** Copy the `wreq-js` native runtime directory into the isolated Next.js standalone output so packaged Playwright/E2E starts can load the instrumentation hook on Linux.
- **fix(api):** Validate the Codex Responses websocket bridge and `/v1/batches` JSON payloads with Zod before use, keeping `request.json()` route validation green and returning explicit 400 responses for invalid bodies.
- **fix(providers):** Add explicit typing to provider alias and category helpers so the strict `typecheck:noimplicit:core` CI gate passes.
- **fix(ui):** Keep the upstream proxy provider detail page labeled with a fallback "Managed via Upstream Proxy Settings" management surface when translations are unavailable.
- **fix(electron):** Harden the production desktop CSP by removing `unsafe-eval` outside development and adding object, base URI, form action, frame ancestor, and worker restrictions.
- **fix(cli):** Replace shell-interpolated setup and privileged command execution paths with argument-based `spawn`/`execFile` helpers for database setup, Tailscale sudo commands, MITM DNS edits, and certificate install/uninstall flows.
- **fix(ui):** Keep provider icons resilient by using direct `@lobehub/icons` components first, then local PNG/SVG fallbacks, avoiding the `@lobehub/ui` peer runtime in the dashboard.

- **Build Core:** Force Turbopack cleanup via Prepbulish script to prevent Next.js 16 app/ routing conflicts on runtime.
- **Provider Quarantine:** Introduces model/provider circuit-breakers with adaptive TTL exponential backoff for recurring upstream errors (#1090)
- **Oauth Keep-Alive:** Safely protects authenticated active accounts against spontaneous dropping from router due to transient token refresh failures (#1085)
