Nightly builds

Cold and warm bake invocations on a rented CodeBuild machine, one job per architecture.

These are not comparable with the instrumented fleet runs. Those measure a parallel build across three nodes with a shared compiler cache; these measure sequential bakes on one rented machine. The phase wall clock is the whole bake, not a per-target cost.
