# Record, per flat-slot object, whether it loads under every supported R minor.
#
# `union_index_records()` keeps a carried flat record when that object is
# recorded safe and drops it otherwise. Objects uploaded before that record
# existed have no verdict, so they are dropped: a full re-index removed roughly
# 2000 records per per-minor index (16398 across the 4.4 indexes, 20076 across
# 4.5, 15532 across 4.6), each one resolving to CRAN source for clients the
# routing serves correctly.
#
# This inspects what is already in the bucket and writes the verdict, which is
# what restores that coverage. Decided by symbols rather than heuristics: a
# binary fails at dyn.load() under minor M exactly when it references a symbol M
# does not export, and the volatile set is derived by diffing the R builds in
# the image.
#
# Re-running is cheap; recorded objects are skipped.
