# Static security analysis, modelled on Agenda Tech's.
#
# Notes Tech 3.0 is Kotlin end to end, so CodeQL now sees the whole app, crypto included. In the
# Flutter versions it only saw the android/ shell and the Dart code stayed out of its reach.
#
# It does not replace detekt: detekt judges style and patterns, CodeQL follows data FLOWS (untrusted
# input reaching a sensitive operation). Neither finds what the other finds, and neither finds what a
# review finds.

      # An explicit build rather than `autobuild`: the project has a KSP chain (Room, Hilt) and reads
      # version.properties at build time. What `autobuild` guesses wrong it analyses less, and a partial
      # analysis that presents itself as complete is worse than none.
      #
      # `--no-build-cache --rerun-tasks`: CodeQL only extracts what it SEES compiled. On Agenda Tech the
      # cache restored by setup-gradle made compileDebugKotlin FROM-CACHE, and the analysis failed with
      # "could not process any of it" while the build was green (2026-09-14).
