func_81207698 (threshold lookup switch, hand-decompiled from asm since m2c
gave a degenerate draft) and func_81208C08 (message-dispatch switch, m2c via
the rodata jtbl input) in fragment1_86CB0. Bare GLOBAL_ASM: 51 -> 49.

Tile-grid draw routine sourcing glyph data from D_8122C748->unk0000; each
m2c "D_8122C748 + offset" maps to &D_8122C748->unk0000[offset]. Bare
GLOBAL_ASM: 52 -> 51.

m2c resolves switch jump tables when the rodata .s defining jtbl_* is passed
as an extra input. Unblocks the 14 remaining jump-table functions.

Correct the prototype to (u16*, s32) to match the actual function, avoiding
a future conflict when func_81202758 is decompiled.

func_81202FCC (timer-driven counter update) and func_812006AC (GB-pak ROM
read with checksum, mirrors sibling func_812008C8) in fragment1_7F9A0.
Bare GLOBAL_ASM: 54 -> 52.

C-first: wrap func_80033D1C, func_800414B8, func_8003F4C0 (3D140/33FE0) and
func_812075C0, func_81209690 (fragment1_86CB0) in #ifdef NON_MATCHING. The
matching build still uses GLOBAL_ASM and stays byte-exact; NON_MATCHING now
compiles these from C. Bare GLOBAL_ASM: 61 -> 56.

Add docs/c-first-plan.md (campaign to write C for every function before
matching), document the macOS build gotchas and Rust matching toolkit in
README/CLAUDE, and record m2c as an optional dev dependency.

Support the C-first campaign: globalasm now detects whether each GLOBAL_ASM
is behind a NON_MATCHING guard; ps-status --c-coverage reports guarded vs
bare counts (the "bare -> 0" metric) with --list/--json; ps-fdiff --file
summarizes every function in a source object, ranked closest-first.

The map parser dropped symbol-less contributions and vram==0 archive
members, undercounting progress by 6980 bytes vs progress.py. Skip
unallocated (vram==0) contributions and synthesize a $_static_symbol for
the leading gap before a contribution's first named symbol, matching
mapfile_parser symbol-for-symbol (8240 symbols / 2204464 bytes).

macOS's BSD iconv mis-encodes an ASCII backslash as the EUC-JP fullwidth
backslash (0xA1C0) after a multibyte character, corrupting \n escapes in
Japanese string literals and breaking the byte-match (~293-byte divergence
in fragment62). Prefer GNU libiconv from Homebrew when present, warn otherwise.

Introduce a cargo workspace under tools/rust/ with a shared ps-core
library and three binaries for the byte-for-byte matching effort:
- ps-status: status of functions pending decompilation. Build-free mode
scans GLOBAL_ASM in src/ (validated: 190 funcs across 68 files, matching
grep); build-aware mode reports byte progress per folder from the linker
.map, porting the progress.py metric.
- ps-firstdiff: first difference(s) between built and expected ROM, with
function naming and jal-target resolution (like tools/first_diff.py).
- ps-fdiff: non-interactive per-function asm diff of built ROM vs baserom
(like ./diff.py -mwo <func>).
ps-core provides parsers for GLOBAL_ASM, symbol_addrs, and GNU ld .map
files (with vram/vrom lookups), a .z64 reader with md5 verification, and a
rabbitizer wrapper for disassembly. All parsers are unit-tested.
Wired into tools/Makefile (cargo build, skipped with a warning if cargo is
absent), target/ gitignored, and documented in README.md and
tools/rust/README.md.
The Python scripts (progress.py, tools/first_diff.py, diff.py) are kept in
place: only the build-free ps-status path can be validated without a ROM
and toolchain. Parity of the build-dependent tools must be confirmed in a
full build environment before removing the Python equivalents.
