  "message": "ast10x0-hace: eliminate remaining panic_is_possible in digest/HMAC path\n\nThe no_panics_test scans the compiled ELF and fails if any panic path is\nreachable. Two root causes remained in the SHA-2 / HMAC code linked into\nthe hace_sha256 binary:\n\n- div_by_zero: chunks_exact(4).zip(..) in load_iv / digest_from_context.\n  ChunksExact stores its chunk size as a runtime field, so Zip::new emits\n  a len / chunk_size division the optimizer cannot prove non-zero.\n  Replaced with index-stride loops over length-proven [u8; 4] arrays.\n\n- copy_from_slice len_mismatch_fail: the staging copies in\n  HaceDigest::update and HaceHmacCtx::update copy between two range-sliced\n  \u0026[u8] of equal-by-construction length the optimizer cannot prove equal.\n  Replaced with zip element-wise copies (no length assert, no division).\n\nAlso hardened the AES IV copies (AesCipher::crypt, AesSkin CBC chaining)\nto use \u003c[u8; AES_BLOCK]\u003e::try_from array assignment instead of\ncopy_from_slice, per the project no-panic patterns.\n\nno_panics_test now PASSES; nm shows no panic_is_possible, len_mismatch_fail,\nor div_by_zero symbols.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e\n",
