Close API-reachable and file-static gaps in the smaller modules (+52 union conditions): kdf 75->91, coding 48->64, wolfentropy 9->13, curve448 54->58 (100%), chacha20_poly1305 43->46 (100%), hash 6->7 (100%), wc_encrypt 16->19, pwdbased 14->17, signature 30->32. Additive cases in the existing tests (one new test_wc_HashTypeConvert), plus wolfentropy/random white-box drivers. Remaining are justified residuals (WOLFSSL_LOCAL wc_CryptKey, dead defensive branches, alloc/crypto-failure err-chains, platform seed sources).
