On 13 January 2024 Lai won the presidency but DPP lost the LY majority, a completed split mandate in Tsai’s last months as incumbent.
Context
CEC canvassed. She was not the presidential candidate. A split is still a dated polarization-and-resilience instrument.
Handover 20 May is the neighbouring completing row. Lai is a related-person successor.
The president of the Republic of China (Taiwan) is head of state under the Additional Articles. She does not write a PRC statute, a US NDAA, a TSMC board minute, or a 2026 Lai cabinet order. She left office on 20 May 2024; Lai Ching-te is president. A blackout is not a finding that every reactor was thereby safe. A Pelosi transit is not a PRC missile. Allegation of a stolen 2018 referendum is not stored as a completed steal. An indigenous apology is not a land-title gazette. A New Southbound brand is not an FTA by itself. A 2024 LY split is not a finding that the 2020 mandate was void.
Why it matters
The path is democratic resilience and polarization: a completed split mandate records rotation with a minority government to follow.

Evidence

What the sources establish
Central Election Commission Taiwan carries the official instrument or communique. Reuters records the same dated act independently.
Established: a 13 January 2024 split: Lai win, DPP LY loss, independently reported.
Not established: that 2024 was stolen, or a unique later statute coefficient from election night.
CEC canvassed. Her party lost the LY. Lai won. She later handed over.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies DPP loses the Legislative Yuan majority as Lai wins the presidency, not a later speech about DPP loses the Legislative Yuan majority as Lai wins the presidency.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Voters chose. CEC canvassed. Her party lost the LY. Lai won. She later handed over. That limit is the alternative to treating office-holding as authorship of every later series.
