You are an adversarial verifier for a FreeCAD-wasm code review. A reviewer claims: SEVERITY: low CATEGORY: hardcoded-paths FILE: /home/magik6k/lcad-wasm/freecad-port/toolchain/configure-stage2.sh SUMMARY: Build scripts hardcode absolute, environment-specific paths and exact tool versions with no parametrization, so they only reproduce on this exact machine. DETAIL/EVIDENCE: configure-stage2.sh hardcodes TC=/opt/toolchains, Python3_EXECUTABLE=/usr/bin/python3 (:27), EIGEN3_INCLUDE_DIR=/usr/include/eigen3 (:32), python3.14 include/lib names (:28-29), Boost-1.86.0 cmake dir (:31), a sqlite3 archive from the emsdk sysroot (:30), and Qt 6.11.1/wasm_singlethread paths (:10-11). rebuild-deps-*.sh hardcode TC=/opt/toolchains and the node path emsdk/node/22.16.0_64bit/bin (:9). None are derived from env/args, so relocating the toolchain root, bumping emsdk (node dir changes), or a different Python/Boost/Qt point release breaks the scripts silently. RECOMMENDATION: Parameterize the toolchain root and tool versions (env vars with defaults), and discover the emsdk node dir rather than hardcoding 22.16.0_64bit. Independently verify by reading the actual file(s) and running git/grep as needed (repo at /home/magik6k/lcad-wasm/freecad-port/FreeCAD, toolchain at /opt/toolchains, deploy at /home/magik6k/lcad-wasm/freecad-port/deploy-gui). Default to REFUTED if you cannot confirm the evidence. Adjust severity to what the evidence actually supports.

I should check the files mentioned in the claim to verify the details.

The configure-stage2.sh script checks out, but those rebuild-deps scripts I'm looking for aren't in the toolchain directory—I need to search elsewhere. There's also a versions.lock file that could be important for understanding the parametrization issue.

I'm verifying the configuration paths from the shell script, checking that the toolchain directory, Python executable, Eigen headers, and Boost CMake configuration are all correctly specified.

Now I need to look into the rebuild-deps scripts that the reviewer mentioned—they claim these files hardcode the toolchain path and Node version, but I can't find them in the repository at all. That's a significant gap in the evidence. Let me search for any scripts that reference that specific Node version to see if it appears elsewhere.

The rebuild-deps scripts don't actually exist, so the reviewer's claim about hardcoded toolchain paths in those files is unfounded. But the findings about configure-stage2.sh hold up completely, with every cited line confirmed.

Now I'm checking the other scripts in the toolchain directory to see if this pattern of hardcoded paths is widespread across the build system.

I'm seeing that the hardcoded paths and versions across the build scripts are confirmed — configure-stage2.sh and the others all reference /opt/toolchains and python3.14 directly. The rebuild-deps files mentioned don't actually exist in the repo, which is a minor gap in the evidence, but the main claims check out against the actual files. This is a low-severity issue since it's just build infrastructure.
Fable
All configure-stage2.sh evidence lines verified exactly: - Line 6: `TC=/opt/toolchains` ✓ - Lines 10-11: Qt `6.11.1/wasm_singlethread` and `6.11.1/gcc_64` ✓ - Line 27: `Python3_EXECUTABLE=/usr/bin/python3` ✓ - Lines 28-29: `python3.14` include/lib ✓ - Line 30: sqlite3 from emsdk sysroot (`$SY/lib/wasm32-emscripten/libsqlite3.a`) ✓ - Line 31: `Boost-1.86.0` cmake dir ✓ - Line 32: `EIGEN3_INCLUDE_DIR=/usr/include/eigen3` ✓ None are derived from env/args. The pattern also holds across sibling scripts (configure-stage1.sh, assemble-python-prefix.sh hardcode `/opt/toolchains` and `python3.14`). One inaccuracy in the evidence: the cited `rebuild-deps-*.sh` files do not exist anywhere in the repo (`find` returns nothing). The `emsdk/node/22.16.0_64bit/bin` path only appears in `opencode/tool-output/` logs, never in a build script. That portion of the detail is unsupported. But the primary file and all of its cited lines are exact, so the finding stands.
