- per-file -O0 mechanism: split text c-subseg into boot@-O0 (src/boot.c) + 800@-O2 via splat resegmentation + Makefile target-specific CC1FLAGS; the boot/main/ game-mode-dispatch module (0x80010000-0x800123F0) is -O0, not the pinned -O2 (per-module compiler mixing, SETUP §5.5). Regression-gated byte-identical. - 4 byte-matches (38->42 real, make check BYTE-IDENTICAL throughout): GameModeDispatch (-O0 register-ptr far member), DebugMenuHandler (-O0 reserved-slot local), CdQueueBusy (-O2 if/else order + branch polarity), CdReadRequest (-O2 early-return fall-through) - PsyQ infra: include/psyq/libcd.h (CdlLOC/CdlFILE from the .gdt) + 4 named symbols (CdSearchFile/CdPosToInt/CdIntToPos/VSync) in symbols.us.txt; func_* stubs renamed - loader cluster non-jtbl COMPLETE (6 matched + 2 drafted): NON_MATCHING drafts of LoaderInitFileTable + ResourceLoadStateMachine (logically faithful, residuals in-source) - tooling: progress.py/difficulty.py fixed for the multi-file split (glob src/*.c, all asm dirs, skip forward-decls); deterministic; 42 real / 4 NM - flywheel: matching-cookbook §6 (-O0 detection + idioms), §7 (PsyQ types/symbols), T4 - build byte-identical 143dbb89f34491258bbc27810d0a12ec8b43a8dd from a full clean cycle

/* psyq/libcd.h — PSY-Q libcd (CD-ROM) types & prototypes used by the file loader.

|
|
* Struct layouts are the authoritative ones from the imported PsyQ 4.0 .gdt
|
|
* (Ghidra category /LIBCD.H) — verified offsets/sizes, not guessed (G1). Function
|

* prototypes use the canonical PsyQ signatures; their symbols are pinned in

|
* config/symbols.us.txt (and already named in the Ghidra DB). Grow this as more

|
* libcd surface is matched. Companion to common.h (provides the u8/u32 typedefs).
