# .github/workflows/no-rom.yml — the ROM-free CI (P33 B7).
#
# What CI can and cannot prove here: this repository's contract is BYTE-IDENTITY of 218 binaries against the
# original disc (`make check-all`, docs/verification.md). That needs the game disc, which is never in the repo
# or in CI. So CI proves everything that does NOT need the disc:
#   * audits   — the tracked tree is public-clean (tools/audit_public.py: no ROM-derived bytes, no purge path,
#                nothing > 100 MiB), every source is text with portable includes, the verbatim-asm manifest has
#                no drift, the cookbook index / Ghidra roster / work-evidence self-tests are fresh, the LZSS
#                decoder's unit tests pass, no stale symbol references;
#   * compile-only — the committed C still compiles with the pinned vintage toolchain (gcc-2.7.2 cc1 from the
#                tracked tarball, maspsx, GNU as) with the Makefile's exact flags; the PR scope is four
#                representative binaries (~1 min), the whole fleet (4,170 TUs) weekly and on demand.
# Byte-identity is verified locally with the disc and recorded in .run/P33/verify/ (docs/verification.md).
