The scraper walks each package's functions the way RetroPie runs them in one shell (assignments, arrays, for loops, brace expansion, $md_id, calls into other packages) and records every link, copy, move and setting that names $biosdir, the addEmulator flags (sdltrs -romfile3), the BIOS read outside $biosdir (basilisk --rom, gngeopi -B) and the launch scripts that exit without their file (fs-uae kick13.rom, reicast dc_boot.bin).
Each package also gets a package record with its rp_module_repo and the systems it registers, which maps a package to the build it compiles. The schema gains package, repo, systems and the moves and package kinds. platforms/retropie.yml is regenerated at 46128cd2: only the launchers section is new.
Six platforms are read from a branch: System.dat, batocera-systems.json, checkBIOS.sh, the MiSTer BiosDB, the RetroPie scriptmodules and the RetroDECK component manifests. Their YAML named the branch, so the native export patched whatever the branch had become since the scrape. Each scraper now resolves the branch head once, reads every file at that commit and writes it into source. The export follows a recorded tarball and a recorded tree as it already followed a raw file URL.
