- S0 (cookbook §15): ran m2c on real ov_SC01_077 stubs (R14). Finding: m2c --valid-syntax output COMPILES via m2c_macros.h (M2C_FIELD = byte-faithful cast); 30/30 sampled targets use only byte-faithful macros. Compiling != matching: the residual is regalloc/schedule -> decomp-permuter is the byte-closer; struct types are an enhancer, not the sole gate (S3/GATE-B measures the lift). ML parked (owner). - common.h: add s64/u64/f64 + M2C_UNK* typedefs + byte-faithful M2C_FIELD/M2C_BITWISE macros (non-faithful m2c macros left UNDEFINED = early 'defer' signal). Byte-neutral: main 143dbb89 (clean rebuild, R22), resident 8e17e02f, ov_SC01_077 d19c9580 all OK. - CURRENT_PHASE.md: Phase 16 plan + S0-S9 gated tasks + Sun-afternoon timeline + known-answer oracle test method.

/* common.h — shared prelude for every matched C translation unit under src/.
|
|
*
|
|
* Created Phase 6 (the asm->c flip): splat emits `#include "common.h"` at the top
|
|
* of each generated src/ file, but does NOT generate the header itself — it is a
|
|
* hand-maintained, COMMITTED file (unlike the gitignored include/ .inc macros).
|
|
*
|
|
* For the all-INCLUDE_ASM scaffold only `include_asm.h` is required; the fixed-width
|
|
* typedefs below are the psyq/sotn convention, here ready for the first matched C.
|
|
* Grow this (PSY-Q types, hardware-register decls, shared structs) as functions match.
