  "summary": "Updates the Guix build scripts for Linux and Windows to map the entire DISTSRC root instead of DISTSRC/src in -fdebug-prefix-map. This makes all source paths in debug symbols relative to the repository root, including generated sources located in the build directory.",
  "problem": "Debug symbols in Guix binaries use relative paths for files under src/, but generated source files (such as capnp IPC proxies) in the build tree retain absolute paths from the Guix build container. This mixed path structure makes it difficult to configure source directory mapping in debuggers like gdb.",
  "card": "Updates Guix build scripts for Linux and Windows targets to apply -fdebug-prefix-map to DISTSRC rather than DISTSRC/src. Previously, generated files like capnp proxies retained absolute build-container paths in debug symbols while normal sources were relative, making debugger source resolution difficult. All source paths in Guix debug symbols are now uniformly relative to the repository root. This resolves issue #34414.",
  "evidence": [
   "Addresses issue #34414 ('guix: Re-evaluate fdebug-prefix-map')",
   "Author verified with `readelf --debug-dump` on Linux and Windows debug binaries that absolute distsrc paths are eliminated, showing `./src/...` and `./build/src/...` uniformly (PR description)"
