+# The list comes from `abi_flat_safety`, written by the flat-safety backfill
+# from the binaries themselves, so it names exactly the objects that fail at
+# dyn.load() somewhere rather than everything a source heuristic suspects. The
+# heuristic calls 93% of compiled packages risky; the binaries say 4.3%.
+#
+# Each object is rebuilt under every R minor installed in the image, with no
+# `--sensitive-only` gate. Since bincraft v5.3.0 the destination is decided by
+# the built binary's symbols in `upload_single_binary()`, so a package needing a
+# per-minor slot lands there and a portable one lands in the flat slot. Gating
+# on the source classifier is what let Rcpp slip through and break every R 4.4
+# client on the slot.
