 establishes ABI linkage; exact promotion additionally requires valid
 MappedNameRef, StringHasher, ElementMap2, stage history, and round-trip evidence.
 
+The repository also carries a prerequisite-only source probe. It builds QtBase
+6.8.2 `Qt6Core` for wasm, then compiles the locked FreeCAD `IndexedName.cpp` and
+`MappedName.cpp` sources without exporting the production naming callbacks:
+
+```bash
+./npmw run build:qt6-wasm-core
+./npmw run build:freecad-naming-source-probe
+./npmw run test:freecad-naming-source-probe
+./npmw run check:freecad-private-naming-boundary
+```
+
+Passing this probe establishes that the private source subset and toolchain are
+cross-compilable. It does not link the production OCCT Worker, does not close
+EX-TSN-02, and does not change `systemExact=false`.

 The versioned JSON request carries document `objectId`, stable positive
 `objectTag`, prior naming evidence, result object identity, result tag, stage
 DAG, STEP/BRep, and OCCT Generated/Modified/Deleted history. No Web fallback is
