[Buildbot-devel] trigger a builder from another builder: a bit of confusion

C should be the triggerable, and the trigger step is in D.

Now, I'm a tad confused about your setup at large. What people usually do is

Build A on changes to the source code.

If A succeeds, do tests, aka, add a trigger step to A, kicking off a
triggerable B.

Not sure why you're running C less frequently, but you could possibly just
trigger it from B, if your tests pass.
