- md_SC03_056 (TEXT_LO 0x4, 4 stubs / 61 ins): 15/17 pointers cluster inside at 0x801CBB50; one outward call
(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).
- the instrument: module-id word, TEXT_LO estimate, absolute-pointer set, lui hi-half histogram, and a
jal->function-start VOTE (starts = prologues ∪ the word after every `jr $ra`+delay — leaf functions have no
prologue, the recall killer of S45's vote_base 4/12); scores a BOUNDED candidate list (5 §S44 slots ∪ 134
IDXTAB DESTPTRs ∪ vote bases): STRONG / CONSISTENT / INCONSISTENT / NO-EVIDENCE; AMBIGUOUS tie sets are
printed, never picked; a payload with no self-reference is REFUSED as base-independent (R43)
- R39 controls run before any emission: md_MAIN_008/011/013/042, md_SC03_073, md_SC02_009, md_SC07_004
re-derive their byte-proven bases top-ranked from their payloads alone (7/7); TEXT_LO estimates == yaml
(incl. the header-table modules 0x7C/0x14/0x158). The first draft of the scorer FAILED 5/7 (prologue-only
starts; a top-rank assertion on modules the bytes cannot discriminate) — fixed by the controls, not shipped
- the five (G5 static-derived, US): MAIN/7 STRONG 0x800CEDF8 (9/9 jals, 14/16 ptrs on starts); MAIN/9 STRONG
0x800CD348 (6/6, 9/9); SC03/53 + SC03/54 CONSISTENT with 0x801EF468 top of a 12-way tie; SC03/56 SPLIT
(jal vote 0x80178C8C vs pointers/lui ~0x801CBB50). T2b probes each with new_binary.sh — the byte gate decides
- SETUP row (R21); evidence rows .run/P32/t2a/evidence.json
- the census's best_draft (.run/wave_g0c/shard30, 174 ins, 7 pins) was a DIFFERENT, wrong body under the bare
name (R48); the journal (R38) named the real one — .run/O21/opus/func_800CB00C.c (88 lines, 7 BLOCK-scope
callee externs: gcc-2.7.2 demotes the later-definition type conflict to a warning at block scope). rtu_match
MATCH 123/123 in the real TU (the S75 redraft too); the S72 resolver had gated only the wrong file, 3x.
- raw splice into src/md_MAIN_034/md_MAIN_034.c; module island pads derived at build (§303); make build
BINARY=md_MAIN_034 -j8 rc 0, sha 46153c06bca859dec05aff59fb1a77d3add3d02b == check (R53); verbatim strict ok
- config/wave_exclude.txt regenerated (exclude_audit --write): the md_MAIN_034 WALL pin labelled a wrong draft,
not a wall — 8 -> 7 entries; docs/backlog.md re-rendered (matched rows drop)
- 0 drafting tokens; no Sonnet agent needed (plan T1c adjusted: no redraft)
- BANK: the stored S71 closeness-0 draft spliced into src/resident/resident_jr_800D128C.c; jtbl_carve --func
carved jtbl_80113FB8 (119 entries, 1 pad word trimmed) + jtbl_80114198 into [0x451c0, .rodata,
resident_jr_800D128C] + [0x453c4, data, tail3]; JTBL_PADS 0,4; make extract + make build BINARY=resident -j8
rc 0, sha 8e17e02ff8954d07c979449198f7e1645046b353 == check (R53). pads_audit ok/ok; interleave_check
ALIGNED n=5; verbatim_check --strict 5==5. Resident stubs 2 -> 1 (func_800D06E8 remains).
- WHY THE GATE SAID DIFF (parallel_gate banked 0/DIFF on an rtu_match MATCH): jtbl_carve.set_overlays_var
regenerated resident_JTBL_INTERLEAVE from the carve set and DROPPED the resident's `--pre hdr.rodata.o`
(§8f leading-rodata sandwich); make extract refused (ld_interleave: hdr.rodata.o would be parked with
.text), the build linked the STALE script (249,252 differing bytes from file offset 0x4), and
harvest_verify._jtbl_prep_one never read the post-carve extract's exit code (R49/R61).
- FIXES (R35/R40/R57): jtbl_carve._merge_pre carries an existing --pre forward (idempotent; overlays
unchanged, 4-shape unit control); harvest_verify refuses loudly on a failed post-carve extract and
restores the snapshot (CARVE refusal, NOT a draft verdict); interleave_check's anchor accepts a leading
--pre (was a false DRIFT n=0 on the resident; control ov_SC02_017 ALIGNED n=44 unchanged).
- cookbook §498 (+ the stale-asm-after-a-failed-extract sequencing law); SETUP rows for all three
- _type_names returned the TAG for `typedef struct Rec801806C8_s Rec801806C8;`, so the typedef block and the
tag's own packed struct definition collided under one key with different bodies and the R43 "CONFLICTING
bodies — a rename is needed" refusal fired on legal C. Now keyed by the alias (_TYPEDEF_TAG_ALIAS); the
`carried` set learns the alias; `typedef struct X X;` (alias == tag) keeps the old key so a second one
still dedupes/refuses. Unit control on 7 block shapes PASS; ov_SC02_017 --only func_80186C64 --dry-run:
2 region files, no carve repoints. cookbook §497; SETUP row.
- jr_isolate_all resident --only func_800D128C: [0x4 c resident] [0x12ec c resident_jr_800D00E4]
[0x2494 c resident_jr_800D128C]; the banked jr func_800D00E4's .rodata carve + JTBL_PADS + --order
repointed to resident_jr_800D00E4.o (config/overlays.mk resident block only, R60); make extract +
make build BINARY=resident -j8 rc 0, sha 8e17e02ff8954d07c979449198f7e1645046b353 == check (R53)
- TOOL FIX (R43/R33): the carried-type test consulted _engine_types() (engine_types.h + common.h) for
every TU, assuming each region includes engine_core.h; the resident includes only common.h, so its
file-local `typedef struct {...} CdFileLoc;` (a name engine_types.h also defines) was silently NOT
carried -> `parse error before cdFileLocTable` in both region TUs, build rc 2 while the stale binary
on disk read green. Now _provided_types(header) derives the set from the TU's own #include lines
(engine_core.h => engine_types.h + common.h, never engine_core's macro-internal typedefs; common.h
=> common.h) and _file_scope_decls(items, provided) uses it at both decision points. R39 controls:
overlay header == legacy set (1,197 names); resident set lacks CdFileLoc. cookbook §496; SETUP row
- rtu_match func_800D128C --split resident_jr_800D128C: MATCH (243 ins) on the stored S71 draft;

Stubs 32 -> 31 after the func_80015760 bank (commit:3877); R22 fleet 213/213 (.run/S79_check_all_8.log);
main game-code 93.5% (38,854 / 41,534). Permuter ILS plateaus recorded with their residual named:
func_80015608 best 1, func_80039B20 best 7, func_80038698 pinned seed refused (11). The ILS runner
had reported "no waypoint" for 8 cycles in 20 s on a seed the permuter's C parser rejects; it now
prints [permuter] REFUSED and leaves PERMUTER_REFUSED.txt (positive-controlled on func_80038698).
Stubs 35 -> 32 after the #7 banks (commit:3873 commit:3874); R22 fleet 213/213 (.run/S79_check_all_7.log).
ov_SC05_018:func_80180BE0 and ov_SC06_010:func_801809E4 have NO draft: their ledger drafts were other

(.run/S79_check_all_6.log); frontier_classify 35 rows (main 16, md_MAIN_003 5, resident 2, ov 12).
jtbl_pads_fix's PAD_ERR_MORE regex carried jtbl_rodata_pads' old wording and reported "no
pad-count drift" over a red build; it now accepts both spellings and, positive-controlled with a
deliberately short spec, reports "emits >4 table(s), spec declares 4". The deferred carves and
their blockers are itemised in §491 and in the checkpoint's task #7 brief.
800c3 (0x8005CE18-0x8005FC68, one contiguous run of 33 interleaved Sony objects) is now four
stub rows — libapi1 (21 BIOS trampolines + COUNTER), libpad1 (PADENTRY + PADMAIN 760), libapi2
(L02/L03), libpad2 (PADCMD PADIF PADPORTD PADSEQD WAITRC2) — fed by two WINDOWED psyq_integrate
calls from the raw .run/obj42/{libapi42,libpad421} dirs (integrate tiles each stub with one
library; every boundary checked against .text SECTION sizes). The apicard region's three
"game code" rows were libapi 4.2's C objects to the byte: 800c2 = FIRST.o (firstfile + the
"no jump table wall" stub func_80062144), 800c2_2 = PAD.o, 800c2_3 = PATCH.o + CHCLRPAD.o ->
apicard5/6/7; make_apicard_used.py sources libapi from 4.2 (the EXE's real libapi; libcard
stays 4.0) into .run/obj42/apicard_used, 26 objects / 7 blocks, no game code left in
0x80061F38-0x80062888. src/800c3.c (129 hand-matched "C", 62 verbatim bodies, 19 stubs incl.
the four §332 %lo-in-a-delay-slot "walls"), src/800c2.c, src/800c2_2.c, src/800c2_3.c removed;
REORDER_TUS is empty (mechanism kept). Cookbook §490.
Two stale instruments fixed: exclude_audit let a pinned WALL outrank LINKED (PopMatrix/
PushMatrix had sat as walls since S68 while living in libgte3, linked since Phase 8) — LINKED
dominates now, config/wave_exclude.txt 13 -> 3; frontier_classify carried a hard-coded 49-name
LINKED set (R51) and reported 337 "stubs" — derived from the Makefile now.
Verified: main 143dbb89f34491258bbc27810d0a12ec8b43a8dd WITH all SDK dirs and WITHOUT them from
a fresh extract; make tools-health OK; R22 fleet extract-all 212/212 + check-all 213/213.

The bounded hunt succeeded on its first lead. archive.org item
`play-station-programmer-tool-runtime-library-version-4.2.7z` (383 KB) is the PsyQ Runtime
Library 4.2 (LIB/*.LIB + INCLUDE, 1998-01-21) plus LIB/42PATCH/J421PD.ZIP — SCE R&D's
1998-02-26 "Libpad.lib version 4.2.1 for the Analog Controller (DUAL SHOCK)" patch, shipping
LIBPAD.LIB 4.2.1 with LIBAPI.LIB 4.2 and LIBPAD.H/LIBAPI.H/KERNEL.H.
Placed and byte-verified against the EXE (psyq_identify 0x8005CE18-0x800629DC, then
psyq_link.py per object): libpad 4.2.1 7/11 — PADENTRY, PADMAIN (760 ins, the 4.2.1 build,
exact), PADCMD, PADIF, PADPORTD, PADSEQD, WAITRC2 — and libapi 4.2 39/88 — the 21 band
trampolines, COUNTER, L02/L03, and the apicard-region C112/A50/A51/A54/A65/A67/A69/FIRST/A66/
PAD/A18-21/PATCH/CHCLRPAD. All 46 PASS. Neighbours for the record: plain libpad 4.2 and the
4.3 disc (DTL-S2340, 1998-05-18; PADMAIN 832 / PADIF 380 / PADSEQD 292) each place only 4;
4.2.1 is the unique exact match, so the game was built between Feb and May 1998.
Banked (R20): the 7z tracked under tools/psyq/ with sha256 + provenance in CHECKSUMS.sha256;
extracted to gitignored tools/psyq/lib42/ and lib421/ (the 4.2.1 headers are the band's
prototype oracle from now on); ELF in .run/obj42/{libpad421,libapi42}. Docs: psyq-worklist
"S79 task #13", SETUP archive table + §5.1 + S79 tool table, CURRENT_PHASE (#13 log; the S79
FINAL block's §5 records the archive and §6 is the re-scoped task #5 brief: link the whole
0x8005CE18-0x8005FC68 band and re-source the apicard region's libapi from 4.2).
The §9.1 "scattered .bss commons" exclusion class (Phase 8 → P31) is closed 3/3. New
tools/psyq_bss_split.py (own ELF32 REL reader/writer) cuts an object's packed .bss into
per-base NOBITS pieces: bases derived from the game bytes per HI16/LO16 pair, references
walked in offset order into single-base runs, cuts snapped to symbol starts (the linker
scattered SYMBOLS), symbols moved, a LOCAL section symbol per piece inserted, relocs
retargeted with the addend rewritten in the immediates, self-diffed. It runs inside the one
prepare step shared by psyq_link.link_object / psyq_link_region.build_region /
psyq_integrate.integrate (prepare_object before classify), re-derived every build.
GS_001.o was certified "5 interleaved bases, NOT splittable" by the S77 probe, which grouped
by BASE; by RUN it is six symbol-aligned pieces. All seven cuts across the three objects are
confirmed by the other objects' by-name recoveries (_que 0x800C5510, _svm_sreg_buf
0x800B9B58, PSDBASEX/CLIP2/PSDBASEY/POSITION/GsDRAWENV). R39 negative control: 235 placed
objects across 9 curated dirs, 0 refusals, exactly 3 splits (a libcd .bss+size end pointer
refused the first build → reference problems are fatal only when a split is needed).
Wiring: yaml 800c→libgpu2, sgap_6→sgap_6+snd12, gsgap3→libgs8 (comments rewritten);
LIBGPU_ELF := .run/obj40/libgpu (curated libgpu_used retired); libgs 34 objs/8 blocks
(make_libgs.sh +GS_001); snd 63/12 (make_snd_used.py exclusions 4→3). src/800c.c and
src/gsgap3.c removed (Sony code hand-matched as REAL/verbatim), sgap_6.c keeps only
func_8003FA54; splat-emitted libgpu2.c/libgs8.c/snd12.c stubs for the no-SDK fallback.
Verified: main 143dbb89f34491258bbc27810d0a12ec8b43a8dd WITH the SDK objects and WITHOUT
them from a fresh extract; make tools-health OK; R22 fleet clean extract-all 212/212 +

(unchanged); game-code weighted 91.1% (40,895/44,870) — both terms lost the 3,667 SDK ins;
the remainder is still exactly the 3,975-ins open-stub sum. Verbatim manifest --update

- exact tiles, 0 tokens: libgte23-26 (MSC01/02/05/09, SMP_00, FGO_01-06, PATCHGTE), libgte9 re-derived

(VM_NO1), snd11 (VM_NOWON carved off sgap_8). LINKED 959->1040, REAL 912->886 (SDK inline-asm wrappers
re-provenanced), VERBATIM 146->85, 13 TUs deleted; splat re-emits the stub records.
- main 143dbb89 WITH and WITHOUT the SDK objects. The no-SDK fallback had been red since S7x
(CdReadyCallback called by its SDK name while the libcd stub carried func_800435B4) — curated
CdReadyCallback = 0x800435B4, refs unified. R22 clean fleet 213/213; tools-health OK.
- METRIC CORRECTION (R35): progress.py's "MAIN game-code weighted" sig never excluded the LINKED
objects (its comment said it did) — ~31k linked-SDK ins sat in the denominator as unmatched game
code. Exclusion now derived LIVE from the Makefile stub lists + yaml ranges: 91.8% (44,562/48,537),
not 59.8%; the 3,975-ins remainder equals the open-stub sum exactly.
- VM_F.o probed SPLITTABLE at .bss 0x50c (SYS.o's class -> task #4). cookbook §488; worklist S78 #3;
decision-log + accelerators; SETUP rows.
- provenance: the psx loader's per-version PsyQ signature sets place PADENTRY/PADCMD/PADPORTD/
PADSEQD (4.2), WAITRC2 (4.3), COUNTER/C114/FIRST/PAD/PATCH/CHCLRPAD (libapi 4.2) byte-exact in
0x8005CE48-0x8005FC68 / 800c2 -> 12 of main's 29 stubs incl. all four §332 walls are Sony's
DualShock library in reorder mode. 46 names -> symbols.us.txt (count 1081), band TUs, verbatim

decision-log + accelerators S78; CHECKSUMS +Psy-Q_46.zip +PSYQ_SDevTC_v4.5.zip.
- psyq_integrate: --yaml maps stub<->objects by SUBSEG RANGE with an exact-tiling check and PRINTS
the located-but-unwired residue (libgte: 13 objs / 1,264 ins) — main's LINKED build had been RED
at HEAD since the S77 psyq_identify fix (22 libgte blocks merged to 3; gate worktrees take the
stub fallback so it never showed); a library object's exported symbol whose recovered address the
curated file names differently is --redefine-sym'd (R15; A66 firstfile->firstfile2).
- Ghidra: 47 MCP renames did NOT persist through the sentinel stop (R9 caught it) -> NEW
tools/ghidra_scripts/ApplySymbols.java + tools/ghidra_apply_symbols.sh mirror the curated file
headless with a real save: 73 renamed, R9-verified x4. SETUP inventory rows (R21).
- lint_symbol_refs: scans verbatim __asm__ bodies (`.ent\tfunc_X` is invisible to \b and to the
string-masked scan); negative-controlled (red on the pre-fix TUs, green on the passing tree).
- R22: clean extract-all 212/212 + check-all green on the final config; main rebuilt byte-identical
143dbb89 after the last src-only fix -> 213/213; tools-health OK.
The fleet report still printed 'caveat is R34: no independent second oracle for
a PS-X EXE'. That was true until this session; make sig-main-oracle +
audit-corpus now cover main at 0 phantom / 0 truncated / 1 explained pad-tail.
A stale caveat is the same class of false statement as a stale wall verdict.
The yaml has excluded SYS.o/GS_001.o/2D_BG0.o/VM_NO1.o from the LINKED build
since Phase 8 for 'scattered-.bss commons ... no single NOLOAD base reproduces
it'. Every word of that is true, and it does not imply unlinkable.
psyq_bss_probe derives each object's .bss bases FROM THE BYTES (for each
HI16/LO16 pair against the bare .bss section, the object's immediates give the
addend and the game's give the resolved address, so base = resolved - addend)
and then asks the unasked question: are the offset ranges DISJOINT?
SYS.o 3,109 ins 2 bases 0x0000-0x0044 @ 0x80078830
0x0148-0x0150 @ 0x800c53cc -> SPLITTABLE at 0x148
GS_001.o 384 ins 5 bases interleaved -> the genuine wall
2D_BG0.o 526 ins NO .bss -> reason cannot apply
VM_NO1.o 305 ins NO .bss -> reason cannot apply
§9.2's escape (weaken the .bss symbol, --defsym it) really cannot reach these —
a relocation against the bare SECTION has no name to defsym — and that is what
made 'unlinkable' look like the conclusion. But a section reference only needs
the section PLACED, and a section can be split.
Completeness checked before believing it (R32): the probe counts .bss refs from
EVERY section; SYS.o's .data has zero, so the two-way split covers every
reference. Placement is derived, not configured — the object is located by
masking relocated fields and requiring a UNIQUE match, which independently
reproduced SYS.o @ 0x80059234 / 3,109 ins, agreeing with both the yaml subseg
bounds and the manifest's psyq_identify count.
Incidental: src/800c.c is 100% SYS.o (its span is exactly the object's .text
size), despite the subseg comment calling it '-O2 game code'.
Cookbook §484; yaml comment corrected in the same change.
The roadmap's completion contract requires both audit oracles green before any
100% claim on main, and main had none: audit-corpus covered overlays and
resident only, and R34 is explicit that the byte gate is a perfect CORRECTNESS
oracle and a NULL COVERAGE oracle — green whether a function was sliced right
or invented, because the .s pieces paste back either way.
sig_image gains multi-range signing, closing all three blockers
docs/second-oracle.md scoped:
* the 0x800 PS-X EXE header -> --vram-base 0x8000F800 puts file offset 0 at
vram, so the header falls below the first range
* interleaved data + linked islands -> --segments derives 28 game-code ranges
from the splat yaml's SEGMENT rows
* one text range -> the signer loops ranges, bootstrapping INSIDE each, which
is what stops the linear partition running through a data island and minting
functions out of it (the detector manufacturing the class it detects)
INDEPENDENCE IS PRESERVED, NOT WORKED AROUND. Ranges come from segment TYPES,
never from splat's function boundaries; entries are still found by byte-derived
jal-closure. Seeding from splat's symbols would make every phantom look real —
the trap the design doc names. .run/sig.main.jsonl (the splat-SEEDED atlas sig)
is a different file and corpus.ORACLE_SIG keeps the audit off it.
RESULT: 986 functions signed. main audit = 0 PHANTOM, 0 TRUNCATED, 1 PAD-TAIL.
Fleet audit-corpus = 0 + 0, unchanged for resident and overlays.
NEW AUDIT CLASS, from the first real finding. func_80062144: splat .s 65 ins,
oracle 64 — the extra line is a nop one line BELOW endlabel. That is an
alignment pad the matching side already emits from C (§295; two S77 wave agents
did it on func_8005E13C and func_8005D538), not a mis-slice. Lumping it with
TRUNCATED would make the oracle's first finding look like a defect and bury the
class that is one.
COVERAGE ASSERTED both ways before trusting it (R32): all 30 game-code stubs
fall inside a range, and 0 of 199 addr-parseable LINKED stubs do.
tools-health caught this red: seven sections added this session without
regenerating the index. Exactly the sibling-update the health gate exists to
enforce.
THE GAP: a drafting agent is briefed to STOP at a plateaued permuter-class
residual — right, since an agent grinding a register permutation burns tokens
for nothing — so every SCHEDULE-REORDER/DELAY-SLOT/REGALLOC-PERM residual lands
unattempted while the local permuter costs no tokens. In S77 the hand-off
happened only when I remembered.
THE CORRECTION THIS TOOL FORCED. §479 v2 claimed the predictor of a permuter win
was 'prior-attempt history: all 3 winners were drafts nobody had worked'.
Building the selector on that claim refuted it immediately: journal_notes
reports prior attempts for ALL EIGHT known runs, winners included (2, 3, 3).
What I had eyeballed was the DRAFT HEADER narrative, a different corpus — the
winners came from a recovery pile whose files carry no header journal. That is
provenance, not evidence.
So the tool selects on the two NECESSARY conditions only (small residual, a
match_one class the permuter can search), prints prior-attempt counts as
information, and puts the unvalidated filter behind --skip-ground, off by
default so it cannot silently discard good work (R39).
AND A BUG IN THE NEW TOOL, caught by cross-checking against known-true numbers:
wave_results globbed journals across EVERY session and did last-write-wins on a
bare function name, so an older wave's row won and carried its stale
draft_path — the sweep reported func_8002AC98 at closeness 73 and func_80015608
at 65 while both drafts measure 1 and 3. R48 inside a brand-new tool. Journals
are now read newest-last and rows are kept only when the draft lives under this
wave's directory. After the fix all seven cross-checkable residuals agree with
what the agents independently reported (9, 8, 7, 3, 3, 1, 1).
§479 now states the honest position: ~3 in 8 at <=4, no validated predictor, and
a note that a yield table is evidence while a story about why is a hypothesis
needing its own negative control before it goes in the cookbook.
gate_main printed ONE recovery chain for every dropped draft, and it was the
SELF chain (fix_arity_callers --any-proto + cast_self_callers) regardless of
what the clashing symbol actually was. Two of the three classes are not that
chain:
CALLEE — §378 does not transfer; cast_self_callers reads the return type off
the draft and cannot cast a callee, so --any-proto runs unprotected
over every call site. S69 measured 60 decls no-protoed, binary RED.
DATA — neither tool in the printed chain touches a data extern at all.
Measured cost of the wrong route THIS session: func_8006252C was dropped on a
clash with itself; following the shape of the printed chain I reached for
scope_demote_drafts first, which aliased D_80078D08 through __asm__ and BROKE
the build. The real blocker was one --sync-decls away. Three tools, wrong
order, one destructive — because the report named a chain instead of a route.
A route is an ORDERED LADDER, not a prediction: for a DATA clash the choice
between adopting the TU's spelling and demoting to block scope depends on
whether the draft can live with the TU's type, which no classifier can know.
The byte gate remains the sole arbiter (G3/P9). Refusals come first (R43/R61a):
a verbatim draft and a NEAR are not declaration problems.
NEGATIVE CONTROL (R39): all 7 S77 drops whose winning tool was already known
route correctly — 2 SELF (cast_self_callers), 1 CALLEE (sync_tu_decls via a
definition header), 4 DATA — and the DATA ladder's order matches which rung
actually won in each case (sync for D_80072978, demote for D_80072960 and
D_80074818). Verbatim draft refused; real-C draft not refused.
Playbook §4b and SETUP updated in the same change.
The first version of §479, written earlier this session on 3 data points, said
the permuter is a one-shot at <=4 mismatched. Five more runs make it 3 of 8,
and the failures are not marginal: a residual of 1 failed while a residual of 4
banked, so mismatch count predicts nothing.
The real predictor is prior-attempt history. All three winners were drafts
nobody had worked. Every failure was a body an agent or prior wave had already
optimised (5, 6 and 4 prior levers respectively). A draft a competent search has
plateaued is plateaued for the permuter too — its wins come from unexplored
neighbourhoods, not from small numbers.
Same predictor as §479's triage paragraph, reached from the opposite direction.
The escape hatch for the declaration-conflict class the reconcile/sync ladder
cannot reach — two anonymous struct typedefs in one TU are never compatible in
C89, so no duplicate spelling works, but block scope turns the error into the
warning the build already emits elsewhere. From main:func_8001FC08 (400 ins),
whose body was solved in S76 and had never banked because nobody asked why.
playbook §2b has called neighbor_ref the biggest measured cost lever in the
wave since S68 (~20x token swing) and documented it as a MANUAL per-card
command wired into nothing — so it ran for approximately zero cards. Packs now
carry an ALREADY-MATCHED NEIGHBOURS block, same additive never-fail contract as
the past-attempt notes. First run: 30/30 targets had a matched neighbour.
It also shipped with a defect that would have silently un-done it:
neighbor_ref reports the SYMBOL-TABLE name, and for an unnamed function that is
Ghidra's FUN_8003a0e4 — which appears nowhere in src/*.c, where the function is
func_8003A0E4. An agent sent to read FUN_8003a0e4 finds nothing and concludes
there is no neighbour. _src_name resolves against the destination TU's own text,
falls back to the address, and shows the symbol-table spelling in parentheses.
Measured: 150 of 150 neighbour names needed resolving; 0 primary names remain
Ghidra-style. Checked against known-true cases first (resolves FUN_8003a0e4,
leaves func_8003A0E4 alone, leaves an unknown name untouched).
R61(b): the pack was asserting a name true of the symbol table and false of the
world the agent works in.
T11 4/7, T12 13 banked of a 34-draft pool, T13 R22 213/213 twice (a green
baseline before the overlay banks and again after all 17).
main REAL 895 -> 899, stubs 46 -> 42. Fleet stubs 82 -> 65, distinct-code
99.3% -> 99.4%, MAIN game-code 57.1% -> 57.3%.
Three gaps found by auditing instead of asserting.
§462 and §463 were MISSING from the cookbook although their commits are
ancestors of HEAD and added 37 and 34 lines. Same silent loss as §464, which
I caught only because I happened to re-check the three sections I had just
written. Both restored from their own commits; all of §460-§476 now verified
present one by one.
SETUP.md had no record of either new tool (R21). Added gate_main_parallel and
sync_tu_decls, plus the oracle corrections a reader needs in order to
re-judge older verdicts: the REORDER_TUS routing in match_one/rtu_match, the
draw_waves --main no-op, the verbatim-draft refusals at three points, and the
§179-C conversion guard.
The playbook had nothing on what to do when a gate banks far less than it
staged — which is exactly what happened this session. Added the triage step:
probe first (CC1-FAIL 16 / DIFF 18 / MATCH 6 on main's 40), sync declarations
for the plumbing class, hand self_decl_tu to cast_self_callers, and expect a
cascade because every bank changes the declaration environment for the drafts
that follow it.
From the S76 Fable agent on func_800226C0 — 670 instructions, the largest
function in the project, matched at closeness 0.
Explains WHY pins so often hurt, completing the arc of §461/§462/§471:
(a) A pinned hard register carries no nonzero_bits, so combine cannot fold
sext(HImode t) into a copy — which is exactly what the target's 228E4
addu/beqz/addu chain is, with cse2 reusing it as the loop multiplier.
The $18 pin that looked obvious was what prevented the fold; one plain
uninitialised s16 t (mul left an unpinned pseudo) unlocked it.
(b) A pin makes reg_n_sets != 1, so birthing_insn_p refuses the §199-A
boost and the value is placed first — a whole-block schedule shift.
Unpinning o/col/sh23/abr fixed the prologue order and two ties.
Rule: if a residual involves a sign/zero-extend fold or a first-in-block
placement, REMOVE pins before adding them.
From the S76 func_8002FF0C agent (166 ins -> MATCH, verified in-TU with a
spliced src/800_b.c compiling rc=0 and all 63 relocs matching).
__asm__ __volatile__("" ::: "memory") is a CSE MEMORY-TABLE invalidator, not
only a scheduling fence, and the colon-less __asm__("") does NOT substitute:
it forces D_800A46D2 to be re-read rather than folded to sign_extend(r), and
without it the function is exactly two instructions short. Pairs with §464
lever 4 — same two spellings, register half there, memory half here.
Write (b*3)<<3, not b*24: expand_mult never honours its target, so b*24
leaves a move copy that survives into the join block and costs a sixth
callee-saved register plus a 0x30 frame. A top-level LSHIFT_EXPR expands into
the variable's own pseudo. General for any constant multiply factoring as
odd<<n.
Independently confirms §470's 'two distinct locals for the same b*24' on a
different function via a different agent — treat as established.
And the house array spelling can be the defect: D_800A46D2 must be scalar at
block scope; extern s16 D_800A46D2[] forces la for both accesses and costs 12
mismatches. A fleet-consensus declaration is a prior, not a law.
