Maintain config/GCBE7D/splits.txt and its generated companions. Use when Codex needs to add or replace unit ranges, import split data from the backup file, seed split ownership, or reason about normalized unit names like ai_1.c and GBA_1.c.
config/GCBE7D/splits.txt, not config/GCBE7D/splits.generated.txt.python configure.py --version GCBE7D --toolchain prodg35 after changing splits or config files.config/GCBE7D/splits.elf_import_backup.txt as a source of candidate ranges, not as something to copy wholesale without review.For safe import from the backup file:
python tools/add_split_from_backup.py --unit <unit>.text,.rodata import unless the task clearly needs more sections.For seed generation from map-style comments:
python tools/generate_seed_splits.py --version GCBE7DFor lookup while editing:
python tools/ai_lookup_unit.py <unit-or-address>python tools/ai_context.py <unit-or-address>ninja if the change is broad.
