I'd like to work on this. I've identified the root cause and have a fix ready. **Root cause:** `_LazySafeSerializer.dumps()` uses `msgspec.msgpack` which returns `bytes`, but Werkzeug 3.0+ removed the automatic `bytes → str` coercion in `dump_cookie()`, causing the `TypeError`. **Fix approach:** Switch the serializer from `msgspec.msgpack` to `msgspec.json` so `dumps()` returns `str`. The `loads()` method tries JSON first and falls back to msgpack for backward compatibility with sessions written before this change. Opening a PR shortly with the fix and tests. --- Drafted-by: Claude Code (Opus 4.6) (no human review before posting) -- This is an automated message from the Apache Git Service.
