+files already in the folder, writing the output named after the part tag:
+
+```bash
+python scripts/build_intlib.py \
+    --schlib <stage>/<tag>/<symbol_name>.SchLib \

+
+This is a pure-Python compile (no Altium needed): it embeds both libraries into one OLE
+compound file, reusing the bundled `assets/templates/intlib_container.IntLib` as the container
+skeleton, and self-validates by round-tripping the embedded libs. The symbol→footprint link
+lives inside the embedded SchLib (its RECORD=45 model link), so the compiled IntLib resolves
+the footprint on its own. Requirements: the `olefile` package, and the `.SchLib` **must** have a
+footprint model link (it will, after step 6b / a proper Ultra-Librarian export) — the script
+exits clearly if it doesn't. If the compile fails, fix the cause (usually a missing footprint
+model link) rather than pushing a folder without its IntLib; the IntLib is now a standard part
+of the deliverable. After it succeeds, the folder holds **five files**.
