# Contributing — clean-room rules

This tree must stay publishable as engine code only. Never commit:
- game data in any form: `.gob` contents, extracted catalogs, saves, textures, strings dumps;
- the original binaries, or anything derived from them by a decompiler/disassembler
  (no decompiler output, no disassembly excerpts, no pasted pseudo-code — not even in comments);
- copied fixture files from the game. Test fixtures are hand-written minimal samples.

Facts *about* the binary (addresses, calling conventions, prototypes, struct layouts) enter this
repo only through `include/generated/sots_addresses.h`, which is generated from the RE repo with a
provenance header. Everything else is written from understanding, in our own words and code.

Real-data tests read `$SOTS_DATA_DIR` (the owner's installed copy) and must skip cleanly when unset.
Run `tools/clean_room_check.sh` before committing.
