Taipei's mayoral race is now set, with the sitting mayor and his main challenger agreeing to face off in an official debate — a clear win for voters who want the two records compared side by side.

• Mayor Chiang Wan-an filed his re-election papers through a proxy on the final registration day and opted into the election commission's official debate.
• His challenger, Puma Shen of the DPP, wants as many official debates as possible, covering child abuse, traffic, public health and urban renewal.
• Chiang is running on family policy: free milk for schoolchildren now extended to junior high, housing for families with kids, and shorter work hours for parents without a pay cut.
• Shen's attack line is that Chiang only patches problems after they blow up, pointing to repeated child abuse cases, rats, tree removals and a costly shade-canopy purchase.
• Chiang is also touting Nvidia's new Taipei site as the anchor of a tech corridor, plus self-driving vehicles and wider use of senior benefit cards.

Outlook: The two will share a stage before the year-end local elections, with child safety and city services likely to dominate.
