The shared extractor now takes its per-repo taxonomy from a config file rather
than CLI flags, so the wrapper shrinks to the one thing it alone knows: the
repo root, which the vendored gate cannot infer because its own default
resolves inside the submodule.
Coverage unchanged at 23/32; the gate reports the scan as '26 (.rs under src,
tests)', which is the config being read rather than defaults being guessed.
