obu-firmware builds against the vanetza-idf C-ITS library, which until now came from the colleague's microbu-esp32c5 tree beside the repository and was not tracked here, so a clone of this repository could not build the firmware it ships. The library alone is now part of obu-firmware, as obu-firmware/external/vanetza-idf: their external/vanetza-idf at commit cf4b99f, unchanged (9775 files; see its PROVENANCE.md). CMake takes it from there by default; -DVANETZA_IDF_DIR still points the build elsewhere. The rest of the colleague's tree (their own VAM firmware, PKI tooling, station-link Python tools, the V2X2MAP bridge) stays out of this repository and gitignored; nothing is pushed to their repository. NOTES.md, docs/06, TODO.md and the pcap verifier's usage line point at the new location.
