# check.sh — THE button (accumulator corpus). Same discipline as the
# *-ed25519-verified repos: compiles every shipped .lean through lean-guard
# and axiom-audits every certificate against its DOCUMENTED exact cone,
# both directions.
#
# Phases: 0 resource/integrity · 1 stub+axiom-smuggling audit ·
#         2 compile manifest · 3 boundary-exact axiom audit
