      "summary": "Reviewed the Hexagon signed-division routine in `src/hexagon/divsi3.s`, which computes `__hexagon_divsi3` and aliases `__qdsp_divsi3` using only local arithmetic, predicates, and looped shifts/subtracts. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.",

      "summary": "Reviewed this Hexagon assembly source implementing fast math helpers such as `__hexagon_fast2_dadd_asm`, `__hexagon_fast2_dsub_asm`, `__hexagon_fast2_dmpy_asm`, and float/double conversion routines. It contains only in-process arithmetic and branching logic; I found no install hooks, network or exfiltration code, credential or secret access, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "This file is Hexagon assembly implementing three fast math helpers (`__hexagon_fast2ldadd_asm`, `__hexagon_fast2ldsub_asm`, and `__hexagon_fast2ldmpy_asm`) that adjust exponents, handle saturation, and normalize/denormalize results.

      "summary": "Reviewed `src/hexagon/func_macro.s`, which only defines two assembler macros for marking function begin/end symbols (`FUNCTION_BEGIN` and `FUNCTION_END`) with standard `.text`, alignment, global symbol, type, and size directives. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.",
