Record vrc_a32cc3b946cc21f5 (signed; recorded against the current head). Caveats: Re-homed from the prover-lane frontier (vfr_b354d1ae5d88038b), where it was originally established and signed under the maintainer key; this consolidates the two kernel-verified Lean frontiers into one. | Fresh vlv_ witness minted in this corpus (vlv_ea36b68e1708ec5d); kernel-clean, no sorryAx — re-runnable via `vela reproduce`.. Artifacts: 1 hash-verified at propose.
