## Prompt
Task Objective: Incrementally insert new user records (`user_id`, `loss_day`) into the `ds=20260608` partition of the target table that have not appeared before.

Inputs:
- `internal_platform_db.t_mg_dws_user_tag_preset_24128_query_engine_103` (source table, containing fields such as `ds`, `user_id`, `loss_day`)
- `internal_platform_db.t_mg_dws_user_tag_user_id_once_24128_query_engine_103` (existing users table, containing previously written `user_id` values)

Processing Rules:
1. Select records from the source table `internal_platform_db.t_mg_dws_user_tag_preset_24128_query_engine_103` where `ds=20260608`
2. Use a `NOT IN` subquery to exclude `user_id` values that already exist in the existing users table `internal_platform_db.t_mg_dws_user_tag_user_id_once_24128_query_engine_103` (deduplication condition: `user_id`)
3. Extract fields: `user_id`, `loss_day`

Output Requirements:
- Output field order: `user_id`, `loss_day`
- No deduplication needed (duplicates are already filtered out via `NOT IN`)

Write Requirements:
- Target table: `internal_platform_db.t_mg_dws_user_tag_user_id_once_24128_cand_query_engine_103`
- Write method: `INSERT INTO` (append)

Please write the final HiveSQL to `result.sql` and execute it.
