- pinned since S76/S79 as PROVED (§474: fold-const.c:882 split_tree merges MULT(MULT(i,2),2) in every C spelling; the two escapes
each cost one instruction — stupid.c adjacency / expand_decl use-brackets); 20 spellings + statement-expression + register
temp forms measured; the S83 hand pass measured four block-scoped forms at 193/131
- the mechanism (dumps + source): split_tree only decomposes MULT/PLUS/MINUS and never distributes MULT over PLUS, so
MULT(PLUS(MULT(i,2),1),2) survives fold; expr.c:5368's EXPAND_SUM distributive law returns (plus (mult (mult X 2) 2) 2);
both_summands (expr.c:5248) + plus_constant cancel the +2 against the -2 into the bare symbol; memory_address -> force_operand
expands the two expand_mult copy;sll pairs adjacent (expmed.c:2227/2244) with no note or variable, so stupid.c's born+2
rule 2-colours v1/a0 exactly as the target and expand_binop's late copy_to_mode_reg(sym) gives la $a0 / addu / lbu 0()
- ruled out from source: a hard-reg pin + shift outer form (191, LENGTH-DRIFT — a REG index makes (plus sym reg) a legitimate

- the real mechanism (global.c:587-608 allocno_compare, pri = floor_log2(n_refs)*n_refs/live_length; find_reg hands the
lowest free reg to whichever parm copy is allocated FIRST): every prior draft merged the 0x14/0x28 tails at C level
(goto L_merge + a `kind` temp), deleting one `sb a2` use, so a2-raw had 3 refs/45 (pri 666) and lost $a3 to a1-raw
(3 refs/26, pri 1153). Writing the 3-case `switch (a2)` with the tails DUPLICATED (the original's tails are merged by
jump.c cross-jump AFTER allocation) gives a2-raw 4 refs/41 (floor_log2(4)=2 -> pri 1951) -> allocated first -> $a3; a

- the Fable agent read the .loop dump: with `a1v = arg1;` written BEFORE `off = 0;` the extend IS emitted first (T1 of the

flipping loop.c:1631's desirability test (threshold 58 ≥ 57) so the D_800C6DD0 address got hoisted (+2 preheader insns and a
register cascade). Nine `__asm__("")` pads instead of seven restore insn_count 59 → "not desirable" → the target's preheader
tail `sll/sra $a1; move $t0,$zero`. Kept: the `$7` pin on i (a hard reg is not a biv, loop.c:3572) and the [][1] table type

- two integration classes the per-draft rtu_match is BLIND to (it splices one draft at a time):
(1) same-TU drafts spelling one global differently — func_800CEEFC `extern s16 D_800B99E8` (file scope) vs
func_800CEF94 block-scope `extern u16 D_800B99E8` -> `conflicting types` only once both are spliced; the
file-scope decl became u16 (func_800CEEFC only stores zero, so the sign is inert there; the u16 load in
func_800CEF94 is the byte-bearing one)
(2) §304 self-defining rodata — func_800CF068's stub .s was the ONLY owner of `dlabel D_800CEDFC`
(".asciz C:\TIMPACK\OPDEMO0.PAT"); banking the body deleted the definition -> `undefined reference to
D_800CEDFC` at LINK (compile-only rtu_match cannot see it). Fix: `const char D_800CEDFC[] = "..."` at file
scope at the extern's position (directly after INCLUDE_RODATA D_800CEDF8, so the island order 0x0/0x4 holds
under the §303 derive stage) + a (void *) cast at the func_8001AA98 call
- closers (cookbook §500-B): func_800CF148's block-scope redecl of func_800CF3B0 now agrees with the TU's no-proto
decl; func_800CF2BC post-increment passes the old counter; func_800CEEFC/func_800CEF94 goto shape +
`(result << 16) == 0`; func_800CF068 hand-drafted from the md_MAIN_008:0x800cee44 twin's shape (remap refused,
reloc 6≠7); func_800CF3B0 leaf-exact 22/22 admitted by the decl fix
- the S77 law: fix the TU by a byte-neutral plumbing commit BEFORE any gate. The asm returns s32 in $v0 and takes no
arguments; the TU's `extern void func_800CF3B0(void *a0, void *a1, void *a2);` (line 91) refused the leaf-exact
22/22 draft (`conflicting types`, a §376/§495 def-side declaration wall — the Haiku FAIL row)
- the no-proto spelling keeps the BANKED 3-arg caller func_800CF390 legal in C89 and admits the `s32 (void)` definition
- make build -j8 rc 0; sha1 2ff702b605ab5cfc18474c464c4c07e5f8ffd48c == config/check.md_MAIN_007.sha (BYTE-IDENTICAL)
- Opus draft (.run/P32/t3/opus/func_801EF6D8.c): 12-arm dispatcher on *(u16*)(a0+0x34) with a 7-arm sub-state-machine
on D_801F1480 duplicated in outer cases 6–11. Idiom 1: `2($sN)` off a lui/addiu-materialised base = a POINTER LOCAL
(`p = &D_801F1480; p[0]/p[1]`), placed BEFORE the switch although the address computation appears after the load
(42 of the 44-ins gap). Idiom 2: a constant-arm ternary consumed directly as a call ARGUMENT lays the third arm in
its own block + j; the if/else-if STATEMENT chain reproduces the target (cookbook §500-B). 85/85 relocations in order
- carve route: jtbl_carve --probe REFUSED the tail carve (the seven tables jtbl_801EF46C..jtbl_801EF53C sit in the
§154-A leading island at file 0x4..0xF0) and named §260; §303 supersedes it for md_* modules — the Makefile's
`jtbl_rodata_pads --derive md_SC03_054` stage produced the spec 0,0t1,0t1,0t1,0t1,0t1,0 at build time; NO yaml /
overlays.mk change (R60 untouched), no isolation (the T1c md_MAIN_034 precedent)
- rtu_match MATCH 604/604 in the real TU (this session); make build -j8 rc 0;
sha1 06bd73dfbdb10748adcbac7093ead5d76131206a == config/check.md_SC03_054.sha; 2 stubs left (func_801F0048, func_801F00C8)

(.run/P32/t3s3/gate/gate_main2.log)
- func_80015B6C (src/800.c, Opus .run/P32/t3/opus/func_80015B6C.c): both journal walls fell — the "$v0/$v1 swap" was an
artefact of the s32 wh[3] frame-slot hack; the corner-copy wall is cse.c canon_reg (make_regs_eqv keeps the FIRST
register canonical) -> a barrier on the SOURCE variable `__asm__("" : "=r"(x) : "0"(x))`; four empty volatile fences
partition block 2 into five phases at zero cost; the 0xE1000200 trailer lui hoist = reuse the $6-pinned tag variable
- func_8002FDE8 (src/800_b_2.c, Opus .run/P32/t3/opus/func_8002FDE8.c): the "regalloc-priority wall" at 35 was the ARRAY
spelling of D_800A46D2 — the block-scope SCALAR `extern s16 D_800A46D2;` (as same-TU func_8002FF0C/func_800301C8) gives
35 -> 3; third `return 1` inside the == -1 arm; the §47 live-length slider COMPUTED from -dl -dg (one fence where the
constant is live and `data` dead); `one = 1;` and `i4 = idx * 4;` as separate statements
- both rtu_match MATCH in the real TU (S82 re-verification); cookbook §500-B carries the closers
- main: 12 -> 7 open (5 pinned walls + 2 NEAR)
- Sonnet draft (.run/P32/t3/sonnet/func_801EF7E4.c): §339's redundant-default test is the switch tell; combined case
labels `case 0: case 3:` place the shared body FIRST, while two textually-duplicated bodies relying on cross_jump
land it LAST next to the epilogue regardless of source order (cross-jump placement is not steerable from C, §500-B)
- rtu_match MATCH 72/72 in the real TU (this session); make build -j8 rc 0;
sha1 c0848f308342e499e2bd8c2db86f6225a29e1592 == config/check.md_SC03_053.sha
- src/md_SC03_053/md_SC03_053.c has 0 INCLUDE_ASM left — md_SC03_053 reaches 100% C
- Sonnet draft (.run/P32/t3/sonnet/func_801EF734.c) after the Haiku FAIL at 47: register-pin the actor pointer
($16, like sibling func_801EF624) and write the shared func_80178CBC(s0, &D_xxx) call LITERALLY in each of three
uniform if / else if / else arms with no early return; cross_jump merges the three jal+epilogue tails and lands
move a0,s0 in each arm's delay slot
- Haiku's plateau was a register-COALESCING failure (early-return if + separate nested if/else → $s0 AND $s1 for one
value: spurious move, extra sw/lw, frame 32 vs 24), not the missing merge it reported (cookbook §500-B)
- rtu_match MATCH 44/44 in the real TU (this session, .run/P32/t3s3/verify/); make build -j8 rc 0;

- fleet baseline before the bank: make check-all 218 passed / 0 failed of 218, EXIT 0 (.run/P32/t3s3/r22_check.log)
- gcc-2.7.2 runs local_alloc (single-block pseudos) BEFORE global_alloc (multi-block pseudos): the three BE-16
hi-bytes are ONE function-scope variable reused across blocks -> global_alloc's $a1 bank, cannot self-coalesce
with the block-local shift dest (the target's `sll $v1,$a1,8` tell) — and its longer live range fixed the p[8]/p[7]
sched1 hoist for free. The prior NEAR-11 drafts pinned hi=$5 at one site only.
- plus an in-place compound on a block temp (u32 t = hi<<8; t |= p[11]) to tie the or to the shift (§219 family), and
ONE pin register u32 len asm("$6") to rotate p/len (all 24 declaration orders inert, as this TU's func_80035270 notes)
- MIDI MThd header parser; no relocations. rtu_match MATCH 74/74 (coordinator-verified); gate_main 1/1 BANKED
- harvest: "multi-block variable = global_alloc bank" — a shift whose dest differs from its $aN source means a
function-scope variable reused across blocks; no statement order reaches it from a per-site temp
- the 11-18 plateau had two mutually-exclusive halves under (A & 0xFF000000) | (B & 0xFFFFFF): preheader hoist order
of the two masks vs &otab[idx], and the $t3/$t4 pairing of the mask register and the slot pointer. store_field ->
store_fixed_bit_field expands the RHS bitfield extract BEFORE the destination read, which fixes loop.c's movable
order [&otab[idx]; 0xFFFFFF; 0xFF000000] AND the ior operand roles at once (operand swap alone = 35). Third witness
for §364's -O2 half (func_8001D3FC/func_80021284/func_80023570 in the same TU already use the idiom).
- kept from the S79 90->18 chain (re-measured): the §194-A fence in both arms, `code` split from its base with
compound accumulation, register u32 base __asm__("$3"), and exactly 13 zero-byte fences after pkt = D_800A5E60
(0->15, 8->13, 10/11/12->7, 13->MATCH). Dropped as now inert: the m24 $11 and e1 $4 pins.
- the S80 permuter waypoint (closeness 11) was semantically UNSOUND (m24 sunk into one arm) and was not used (R63).
- rtu_match MATCH 281/281 (coordinator-verified); gate_main --apply 1/1, main byte-identical
- the redundant D_80073140[i] re-read was spelled *(s32*)(base1 + i*4): a cast-wrapped PLUS is DENIED the /s
(MEM_IN_STRUCT_P) grant (expr.c:4570-4576, §30a#1), so true_dependence kept the edge to the fixed-address
D_800C7D20 store and pinned the re-read below it. ((s32*)base1)[i] makes the INDIRECT_REF operand a top-level
PLUS_EXPR -> /s granted -> the load hoists into the D_800C7D20 load-delay slot. Zero drift, first compile.
Load-bearing kept: $6/$7 pins on i/off (-23 without), the volatile launder on the D_80073140 base (-39 without).
- lesson for the router: "redundant re-read scheduled at point-of-use" -> §30 first, never the permuter (it cannot
reach an alias flag from C — why S80's ILS plateaued at 7 from a seed of 7). Harvest note in .run/P32/t3/.
- rtu_match MATCH 79/79 (coordinator-verified); gate_main --apply: 1/1 compatible, BANKED, main byte-identical
- 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'). Idioms:
§162k1 QImode (u8)(c-3)<2; explicit flag temp t=(u32)(r-0x64)<0x1E, s1=t^1; switch decision trees for both
currentLocationId dispatches. reloc_identity AGREE 50/50; rtu_match MATCH 344/344 (verified by the coordinator)

(0x8018151C) hits a function only 3 overlays have, ov_SC03_002 among them; req_fit 9/9 for ov_SC03_002
- payload_base_evidence.py v2 (controls 7/7 throughout): (a) STRONG = internal jals + fn-ptr-table entries on the
module's own starts >= 2 (SC03/53 STRONG); (b) OUTWARD-EXPLAINED — a pure jal-vote base whose "internal" targets
are function starts of the fleet's overlays is downgraded: SC03/56's 0x80178C8C was two SHARED-engine functions
spaced like two of its five starts (and nobody's DESTPTR), a false STRONG; (c) the requester cross-check is
informational only — shared engine code makes every requester fit (an R39 control caught it scoring: 6/7)
- memory-map §S45 p7 amended: all five rows ONBOARDED + the two instrument findings (the first build is a NULL
oracle for FINE base errors — +8 builds byte-identical, +0x1000 fails the link; outward-explained vote bases);
SETUP row amended. The parked-for-L3 ledger is EMPTY pending `make audit-disc` (T2c).
- md_SC03_053 (TEXT_LO 0x4, 15 stubs / 372 ins) and md_SC03_054 (TEXT_LO 0xF0 — a 19-entry fn-ptr header, 7 stubs
/ 764 ins) share ov_SC03_001's DESTPTR slot 0x801EF468, the slot the S45 tracer watched other SC03 scripts load into
- BASE EVIDENCE (memory-map §S45 p7, static-derived STRONG at 0x801EF468 and nowhere else): SC03/53 — 52/75 absolute
pointers inside, 3 of them + its one internal jal exactly on its own function starts (0 at every rival); SC03/54 —
106/115 pointers inside, 5 header-table entries exactly on starts (0 at every rival); lui 0x801F ×18 / ×46
- first builds byte-identical (base-lenient, R34 — the base rests on the alignment; the first internal-call C bank
byte-proves it); the §S45 p6 "onboard at 0x801EF468, let the first build decide" step, finally run
- tools/new_binary.sh md_MAIN_009 extracted/retail/MAIN.CD.dir/FILE_009.dir/0.1 0x800CD348 0x3C -> first build

lies below the resident's symbol region, so the default symbol stack stands (no A4 edit)
- BASE EVIDENCE (memory-map §S45 p7, static-derived STRONG): 6/6 internal jals and 9/9 absolute pointers land
on the module's own function starts at exactly ONE base, 0x800CD348 — inside slot B's region (+0x82C from
0x800CCB1C), not a previously known slot; lui 0x800C/0x800D ×51. Same caveat as md_MAIN_007: the first build
is base-lenient (R34), the base rests on the alignment and will be byte-proven by the first internal-call C bank.
- tools/new_binary.sh md_MAIN_007 extracted/retail/MAIN.CD.dir/FILE_007 0x800CEDF8 0x34 -> first build
BYTE-IDENTICAL sha 2ff702b605ab5cfc18474c464c4c07e5f8ffd48c; A4 applied (symbols.resident.txt not stacked —
the window lies inside the resident's symbol region), re-extract + rebuild byte-identical; 19 stubs (802 ins)
- BASE EVIDENCE (memory-map §S45 p7, static-derived): STRONG — 9/9 internal jals and 14/16 absolute pointers
land on the module's own function starts at 0x800CEDF8 (the boot slot of md_MAIN_001/008/011); lui 0x800C/0x800D
- HONEST CAVEAT (R34, measured 2026-09-05): the all-INCLUDE_ASM first build is a NULL oracle for FINE base
errors — the same payload builds byte-identical at 0x800CEE00 (+8) — and catches only GROSS ones (at +0x1000
two internal jal targets leave the window: `undefined reference to func_800CEEA4/func_800CF3F4`, link fails).
The base therefore rests on the static alignment, and will be byte-proven by the first C bank that calls an
internal sibling. Controls: .run/P32/t2b/{control_full,control_fine}.log
