* feat(binary-layout): admit ELF32 i386, ARM and MIPS layout profiles inspect_binary_layout refused every ELF32 object, so router and IoT firmware (ARM32, MIPS32) got no layout facts at all. The pwntools adapter now admits EXEC/DYN/REL objects in these profiles: ELF64 x86-64, ELF32 i386, ELF32 little-endian ARM and ELF32 little- or big-endian MIPS. Header fields are read in the declared byte order, the ELF32 header is bounds-checked at 52 bytes, and pwntools' own reported architecture, class and byte order must match the admitted profile. Other machines, classes and byte orders keep an unsupported_target refusal that names the admitted profiles. The output schema admits exactly those architecture combinations, and the Evidence subject now names the reported machine instead of always claiming x86_64. verify:binary:layout cross-compiles i386, ARM, MIPS and MIPSel executables and relocatable objects (never executed) and checks every section name, address, offset and size against GNU readelf through CLI and MCP. The real-binary-layout workflow installs those toolchains.

Install the four target libc development packages explicitly. Refs #6934 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(binary-layout): size the minimum symbol entry by ELF class The relocation reference check required a 24-byte Elf64_Sym entry, so every positive symbol reference in an ELF32 report was refused as unreadable output. Elf32_Sym is 16 bytes; take the minimum from the reported class. A 64-bit table with 16-byte entries is still refused.
