A bundle stands on the toolchain it is compiled in (hq issue 211)
A manifest names its toolchain by language, not in build.on, so the planner did not know a bundle depends on the module that publishes its toolchain and built the two in one tier: the bundle against the old toolchain, recorded as built from the new commit. The edge is read from the manifest, so it holds before any build recorded it, and a toolchain that moves rebuilds every bundle compiled in it.
