- tools/new_overlay.sh: one-command overlay onboarding (template instantiate + @TRAILING@ carve + overlays.mk + 4-dict sentinel-insert + extract/build/check); idempotent (re-run = no-op, no dupe entries) - T3: ov_SC03_001 (free-roam, 815,887 B) byte-identical f8fd92f5 - T2 (onboard): ov_SC01_005 + ov_SC01_006 (byte-identical pair) both 56760dbe - template tokens unquoted (correct YAML int types); SETUP §2.8 MCP-reconnect note (R21) - 6 binaries now build byte-identical (main, resident, 4 overlays)

# asm-differ project config — BFM-decomp (SLUS_007.26, USA, PSX little-endian R3000).
|
|
#
|
|
# The matching oracle: diff one function's codegen in our build against the
|
|
# byte-identical `expected/` baseline. Object mode (-o) is the default workflow:
|
|
# .venv/bin/python tools/asm-differ/diff.py -mo <function> # -m rebuild, -o vs object
|
|
# Score 0 = matched (instruction-identical incl. regalloc); anything else = not matched.
|
|
#
|
|
# `expected/` is a snapshot of a SHA1-GREEN build (= the original bytes, since the
|
|
# all-INCLUDE_ASM build is byte-identical). Re-snapshot it ONLY after a green build
|
|
# (`make expected`) — a stale baseline causes phantom matches/regressions (SETUP.md §6.4).

# signature we don't control, so the active binary is selected via the BFM_BINARY env var

# (default main = the retail EXE; a Gen2 binary adds an entry + sets BFM_BINARY=<alias>).
