- the Opus drafter recovered the closeness-0 body the journals (attempts 1-3) pointed at (.run/S71b_1/fable/) — the pack's inline 292-draft was the wrong one — and found the real blocker: the TU defines Struct80078E78 AFTER the slot with a layout lacking bytes 0x36/0x37; only a BLOCK-scoped typedef under a distinct tag (Blk80078E78) + a block-scoped extern compiles (decl-hoisting resolver variants recreate the S7x 'conflicting types').

# splat config — Brave Fencer Musashi resident engine blob (MAIN.CD/FILE_010/1.1)
|
|
# Phase 10: rebuild the always-resident engine blob byte-for-byte from disassembly
|
|
# (100% INCLUDE_ASM), as the project's SECOND build binary (alias `resident`).
|
|
#
|
|
# Mirrors config/splat.us.exe.yaml's PSX options (compiler PSYQ, subalign 2,
|
|
# section_order rodata/text/data/bss, find_file_boundaries False) but for a FLAT
|
|
# decompressed blob:
|
|
# - NO header segment (not a PS-X EXE; first word is data 0x00000036, code at +0x04)
|
|
# - NO gp_value (-G0 like the EXE — verify zero ($gp) refs in the disasm, T2)
|
|
# - single code segment @ vram 0x800CEDF8 (load address RAM-proven, Phase 3 T6b)
|
|
# - output nested under asm/resident + src/resident + build/resident (per-binary, so
|
|
# the Makefile OBJS glob keeps it disjoint from main's asm/ + src/)
|
|
# - per-binary undefined_*_auto paths (under build/resident/) so main's stay verbatim
|
|
# - stacked symbols: config/symbols.us.txt (the 27 shared engine globals the blob
|
|
# references) + config/symbols.resident.txt (blob-local, R13/R15-tagged)
|
|
#

|
|
# slot 0x80128158). The text/data split is ITERATED against `make check BINARY=resident`
|
|
# in Phase-10 T2 (the Phase-5 precedent); this scaffold starts as one code subsegment.
