Soong needs every transitive edge spelled out as static_libs — the old
generator emitted bare imports, so consumers compiled but failed at
dex/runtime (this bit coil). Now each artifact's POM is parsed:
compile/runtime deps become static_libs; in-group deps are auto-downloaded
into the same repo (KMP -android variants probed); out-of-group deps map
to in-tree module names via coordinate_map (null = ignore), with warnings
for anything unmapped. Explicit deps: lists merge in; pom_deps: false or
--no-pom opts out. Config: coil pinned at 3.5.0 with the full six-artifact
graph, splashscreen 1.0.1 added, accompanist gains drawablepainter.
