Resource-match the OMA reference in the key-length sweep (oma_ser_keylen), which gives it the L/16 combining gain the longer frame allows. The proposal now passes a resource-matched OMA by 1.27x at L=64 rather than the 4.3x reported against a fixed-d reference. Densify the JSR, sensitivity, and brute-force grids so the curves are smooth, give the index cipher its channel floor instead of error-free reception, and add the permutation-key known-plaintext attack (exp_permkpa) so Fig. 7 carries a conventional linear scheme. Add check_cov_attack.py and check_cov_ceiling.py: a referee raised a ciphertext-only second-order attack; the exact-population test shows the received covariance leaks only a sparse rank-deficient subset of the key Gram and leaves the eavesdropper at the random-guess level. Dump verify_math.csv, move the superseded V=256 pilot CSVs to data/pilot.
