Matches 69 US functions (50 in net.text, 4 in game, 3 in core, 12 in level overlays): near misses from my earlier batches and drafts that are now exact, plus a few from a fresh batch.

How they were matched

Most were a few instructions off. What closed them:

• Comparison operand order: retail loads the right-hand field first in a->x < a->y; written a->y > a->x it matches. This closed a family of net.text assert getters at once (func_01F056C8, func_01F0574C, func_01F060F4, func_01F06248, func_01F0B0EC, func_01F0B150, func_01F0B478, func_01F0B6D8, func_01F0B778, ...).
• -fno-optimize-sibling-calls where retail calls with jal and returns instead of tail-calling (several net.text functions, under @ee296).
• Field and argument types: u8/s8/s16/u16/f32 fields where retail uses lbu/lb/lh/lhu/lwc1; callees with the argument count retail sets up (an assert taking two arguments, a fifth argument in $t0, memset(arg0, 0, n) where m2c dropped arg0).
• Pointer steps and indexing m2c scaled by the element size (s32 *p; p -= 4 that is 4 bytes, arr[i] for i * 4 + &arr).
• Store order, solved by inverting the scheduler's permutation (compile, see where each store lands, write the stores in the order that lands them where retail has them).
• Profiles: the file's own cflags line, picked among the ones docs/TOOLCHAIN.md documents (@ee296, @ee29, @ee32-040921, -G0, -mno-split-addresses, -fno-optimize-sibling-calls).
• a few rewrites of control flow (early returns, a single result variable, goto loops where a for adds an alignment nop).

No #define aliases, volatile, inline asm or hard-coded addresses: m2c's #define D_x (D_x_[0]) aliases are replaced with extern T D_x[] indexed [0].

func_01EEE33C had a draft in nonmatching/; the draft and its README row are removed.

Verification

On main at 4a7372f:

• full tools/build.sh, build_libgcc.sh, build_libm.sh;
• tools/audit_matches.py and tools/audit_relocs.py: no line names any of these functions;
• config/{us,pal}/map.tsv changed only on these rows (match_map --write with and without the new files, applied as a delta), then match_map --check;
• progress.py --check for US and PAL: US 7,163 → 7,231 and PAL 7,644 → 7,709 (counts are per distinct function).

Independent of #128, #130 and #132 (no file in common).

Reserved in #112.
