A Practical Framework for Flaky Failure Triage in Distributed Database Continuous Integration

Jun-Peng Zhu, Qizhi Wang, Yulong Zhai, Yishen Sun, Sen Chen, Kai Xu, Peng Cai, Hongming Zhang, Heng Long, Liu Tang, Qi Liu · 2026

Flaky failure triage is crucial for keeping distributed database continuous integration (CI) efficient and reliable. After a failure is observed, operators must quickly decide whether to auto-rerun th…

Diagonalizing Through the $\omega$-Chain: Iterated Self-Certification on Bounded Turing Machines and its Least Fixed Point

Miara Sung · 2026

Bounded self-certification in Turing machines fails because self-simulation necessarily incurs a strictly positive temporal overhead. We translate this operational constraint into a domain-theoretic f…

Constructive and Predicative Locale Theory in Univalent Foundations

Ayberk Tosun · 2026

We develop locale theory constructively and predicatively in univalent foundations (UF), with a particular focus on the theory of spectral and Stone locales. In the context of UF, predicativity refers…
