   Done in #92:

   • Z3 4.15.4 → 5.3.1 in the executor and the explorer. The explorer keeps the previous regex solver (smt.seq.regex_monadic=false), because the new default turned a SAFE task into a timeout.
   • JavaSMT 6.0.0 plus upstream fix 3113516df, vendored in libs/maven.
   • ASM 9.11.1, Jackson 2.22.4, logback 1.6.5, SLF4J 2.0.20, Spock 2.5, Mockito 5.24.
   • Gradle 8.14.6 and the plugins.
   • The Python dependencies and the CI actions.
   • Kept: Gradle 9, because the Spring Boot 2 plugin of the target apps fails under it.
   • Measured on all 1713 runs: +8 points, 0 new wrong verdicts. coral81 and Optimization2 time out because some FP queries are slower in Z3 5.x.

   Worth trying before Nov 17:

   • try the monadic regex solver first, then fall back to the old one;
   • symbolic DREM/FREM, now that the Z3 FP fixes are in;
   • incremental solving over shared path prefixes.

   Note: the global Z3 options of the JavaSMT fork (feature/z3-native-options) never took effect, because the build uses Maven JavaSMT. The key solver.z3.timout in ThreadContext is also misspelled.
