aprop_autodraft over regenerated A-prop cards (582 mechanical drafts), reloc_identity
pre-filter (509/582 AGREE), sweep_parallel gate across 107 binaries in 54m35s.
Result: 390 banked of 511 gated (76.3%).
This lane was invisible until the atlas KeyError fix earlier this session: member_lever
emitted the confidence value 'aprop-pure' that _CONF_RANK never contained, so atlas.py
died on the first group carrying such a vote and could not produce an atlas at all.
With it fixed the remap lever shows 235 groups / 812 instances / 46,240 instructions.
The new head plumbing class after the symbol-kind fix: `conflicting types for func_80175414` (27
member-rows). Byte-true DEF is `void func_80175414(s32 _arg0)` (its DEFINE_ macro). The fleet
declared it 1,845 times in four spellings, of which three are the SAME TYPE (parameter names do not
participate) — the outlier was 28 sites declaring `(void)`.
conform_decls REFUSED the naive conform and was right to: 29 ZERO-ARG CALL SITES exist across 28
files, so conforming the declaration alone turns each into `too few arguments` — a fleet-wide
COMPILE break the per-binary gate cannot see (the tool cites 138/140 binaries, measured). It named
the count, the consequence, why the cheap check misses it, and the flag that repairs it, then
forced the two-step: --cast-zero-arg-calls (29 sites cast to the 0-arg fn-ptr shape, §17a-1 — gcc
folds the cast of a known symbol to a direct jal, so it is codegen-neutral), then the conform.
Result: 1,845 declaration sites rewritten across 1,061 files, 0 non-canonical remaining (axis
complete, R32). R22 clean-fleet: check-all 213 passed / 0 failed of 213.
WORTH RECORDING AS A TOOLCHAIN STANDARD: this is the instrument that has not wasted a cycle today.
Every other one reported SUCCESS over a defect — a classifier that discarded every gcc-2.7.2 hard
error (no `error:` prefix), a diff that miscounted 116 data-bundled .s files, a --verified-out
truncated to zero bytes over 62 real banks, a --band default that reported "0 families" on a real
135-member family, and a scope stamp describing the filesystem instead of the run. conform_decls
reports FAILURE with a repair path. A guard must state its COVERAGE, not just its verdict; the
in-repo exemplars are this tool and the §53 jr interlock.
The one-line fix committed ahead of this run (CdFileLoc_80128C98 aliasing CdFileLoc) cleared the
largest remaining propagation-sweep class. Re-sweep: 138 member-matches banked, failures 875 -> 737,
`conflicting types for cdFileLocTable` gone entirely (136 -> 0).
Derived net (138 INCLUDE_ASM removed, 0 re-added) equals the report's 138 — they agree.
R22 clean-fleet: check-all 213 passed / 0 failed of 213.
Fleet 94.2 -> 94.3% instr / 87.9 -> 88.1% distinct / 96.15 -> 96.21% fn-count; stubs 13,780.
Residue reclassified — no symbol dominates any more: 227 PLUMBING-other, 125 DIFF (real byte
divergence, 17%), 93 CC1-FAIL(no-diagnostic), 26 memcpy, then a tail of small data-symbol
conflicts (D_80114F24 12, D_800AE620 11, D_800183E0 9, D_80126B58 6, D_80078EB4 6).
CC1-FAIL rose 77 -> 93 and that is NOT a regression: members that previously died earlier on the
cdFileLocTable conflict now reach a different compile error. Those 93 are hard gcc errors whose
text the sweep's classifier discards because it greps for `error:`, which gcc-2.7.2 never emits on
hard errors. That classifier is now the highest-value instrument fix left — three times today a
no-diagnostic verdict concealed something cheap.
scope_data_externs §8d drops the draft's decl of any symbol the TU already declares at file scope.
It keys on the SYMBOL, but a §37 asm-label ALIAS binds a DIFFERENT C identifier to that symbol:
the TU declares `D_801851BC`, it does NOT declare `tbl_D_80187044`. Dropping the alias left the
body referencing an undeclared name, which cc1 reports with no `error:` prefix — so the sweep
classified all 132 siblings as CC1-FAIL(no-diagnostic), i.e. as a codegen wall.
The bitter part: the alias exists PRECISELY BECAUSE the TU declares that symbol with a conflicting
type (a `void (*[])(void)` dispatch table vs this function's 20-byte-stride view). The drop rule
fired on exactly the declarations written to survive it. Why 1 of 2 died was fully determined:
tbl_D_80187048's symbol is not in the TU, so it demoted normally.
Fix: is_asm_alias() — an alias is demoted into the body, never dropped (the identifiers differ, so
it cannot collide with the TU's decl). Control-tested 6 ways incl. self-labels and plain externs.
Measured: func_80132018 3/135 -> 135/135; full re-sweep +16 more. Total +148 members.
R22 clean-fleet 213 passed / 0 failed of 213. tools-health OK, dedup-check 1949/0.
Fleet 96.11 -> 96.15% fn-count, 87.8 -> 87.9% distinct; stubs 14,120 -> 13,972 = -148 (2nd oracle).
CORRECTION TO MY OWN CLAIM (R14): after the probe I said the 58% aggregate was concealing a broad
problem. The re-sweep refuted it — only 16 more banks fleet-wide. The alias class really was one
family; the first read ("outlier") was right and the correction was wrong.
875 sweep failures classified: 231 PLUMBING-other, 141 DIFF (real divergence, only 16%),
136 `conflicting types for cdFileLocTable` (ONE symbol — biggest single class left),
77 CC1-FAIL(no-diagnostic), 26 memcpy, 12 D_80114F24, 11 D_800AE620, 9 D_800183E0.
STILL UNFIXED, and the most dangerous instrument left: the sweep's failure classifier greps for
`error:`, which gcc-2.7.2 never emits on hard errors. Every hard error therefore reads
CC1-FAIL(no-diagnostic). That is how a missing declaration looked like a codegen wall across 132
functions. rtu_match was fixed for this at T0(b); this classifier was not.
family_sweep --hseq --band all -j 8 over every matched-exemplar family: 553 families /
203 overlays / 1,419 banked / 1,023 failed (58%). R22 clean-fleet 213 passed / 0 failed of 213.
tools-health OK, dedup-check 1949 validated / 0 failed.
Fleet: 93.9 -> 94.2% instr / 87.2 -> 87.8% distinct / 95.72 -> 96.11% fn-count.
Second oracle (R34): INCLUDE_ASM stubs 15,542 -> 14,120 = -1,422, equal to the diff-derived net
(1,451 removed - 29 re-added = 1,422 = 1,419 sweep + 3 probe). Three independent counts agree.
B -> C -> P IS ONE CHAIN, NOT THREE WINS. 1,102 of the 1,422 landed in ov_SC02_037 (409),
ov_SC03_107 (364), ov_MAIN_012 (329) — the three newly-onboarded binaries from C, which had never
been wired into the shared-body ecosystem, so every matched exemplar was unreachable from them.
B fixed the declarations, C wired the include, P poured through the opening. A repeat sweep will
NOT pay like this; the opening was one-time.
S47 total: 1,481 functions banked with zero agent drafting, all from removing plumbing.
Two findings recorded, neither fixed (deliberate, costed):
- --band defaults to `substantial`: the first probe returned a confident {"families": 0,
"banked": 0} on a real 135-member `mid` family. Always pass --band all.
- The alias-gather defect: probe on 0x80132018 banked 3/135, all 132 failures classified
CC1-FAIL(no-diagnostic) because gcc-2.7.2 emits no `error:` prefix. Real error is
`tbl_D_80187044' undeclared` — the exemplar declares TWO §37 asm-label aliases and uses both,
family_remap carried one. T7-S1's "gather" class. Measured as an OUTLIER (aggregate 58%),
which is why the sweep ran before the fix.
Refused by design, all named: 50 jr families / 183 member-slots (§53 interlock — it printed its
own coverage and reason), 264 STRUCT, 112 unresolved immediates, 3 not-stub.
Task B, re-scoped from evidence. The 129 dedup_extend failures are 106 conflicting-types /
21 CC1-FAIL / 4 undefined-ref / 3 DIFF — real byte divergence is 2%, and memcpy is 17 of 106,
not the story. Direction reversed too: the byte-true DEF of func_80128ED8 is what the target
.c files already declare; engine_core.h's macro-local extern was the stub-era guess.
Conformed 8 axes to byte-truth (func_8012F14C 2843, func_8012E5CC 2052, func_8012F038 2214,
func_8014C568 1816, func_80128ED8 1524, func_8012C750 406, func_8012C0EC 50, func_80144A04 25).
R22 clean-fleet: check-all 213 passed / 0 failed of 213. Zero functions banked by design.
Tooling (R33/R35) — three guards that asserted completeness over a narrowed population:
- NEW tools/macro_draft.py: a deduped fn has no definition in any .c (body lives in a DEFINE_
macro), so conform_decls had been refusing the largest class it was built for.
- conform_decls skipped engine_core.h wholesale as "a defining TU": 10 stale externs survived
while 1,514 fleet sites moved, and it still printed "axis complete". Skip now scoped to the
defining macro's span.
- Return-axis compare was literal: typedef int/s32 and a missing `extern` faked a return change.
Now compares normalized types.
- §85 consumer scan under-reported (the dangerous direction): a cast between `=` and the call
hid `s0 = (s32 *)func_80144A04(...)`. Now classified by position, validated both ways.
Corrections to my own predictions (R14): the documented scalar-narrowing hazard was benign
across 2,052 sites; the breaks were arity (6 call sites, fixed with §17a-1 fn-ptr casts) and
the consumer-guard gap. A header-only first probe broke ov_SC01_000 — §85 is literal.
Not done, named: memcpy (builtin codegen), ApplyMatrixSV (no DEF), gte_SetRotMatrix (link bug),
func_80147364 (unparseable macro), D_800AE620/D_80126CC4 (data axis). Cookbook §159.
The S45p9 blocker is closed, and the recovery loop that kept it from finishing is rewritten.
- BANKED: dedup_propagate --auto-from ov_SC02_037 --recover -> 29 functions propagated,
141 overlays byte-identical, dedup 1920 -> 1949 groups, member instances 246,284 ->
249,099 (+2,815). make clean && extract-all && check-all -> 213 passed / 0 failed (R22).
- WHY IT FINISHED THIS TIME: gate_all -> gate_failures returns EVERY failure from the sweep
that already computed them, and the recovery loop resolves them all per round. Converged in
3 rounds; the old one-overlay-per-sweep design needed ~138. That reframes the S45 run — it
was not nearly done when it died, it had barely started.
- Batching did NOT cost capability: per-overlay necessity probes excluded four of the nine
culprits from only the 9 overlays that needed it (not all 138), and ov_SC07_006 was
RECOVERED by the Part-B caller-extern reconcile instead of excluded.
- Plan phase parallelised: 5 min -> 26 s, plan + skip classification byte-identical. Its
compiles_standalone temp file is per-call now — the fixed `t.c` was the same fake-isolation
class as match_one's shared --work dir (P28 T5), latent until something ran it in parallel.
- docs/accelerators.md (NEW, Drew 2026-08-07): the reusable-workflow ledger — what we learned
late that a future decomp should know on day one, each entry with when we found it, when it
WAS findable, what it cost, and the honest prerequisite where one exists.
The two functions the roadmap has carried as PERMANENT WALLS since Phase 24 are matched in all 138
overlays. Neither needed a siege. Both matched from drafts ALREADY ON DISK.
func_80178004 165 ins x 138 = 22,770 Phase 26: Fable5, ~477k tokens, "intrinsic 3-integer
regalloc wall". THREE stored drafts report match_one
MATCH today; one banked first try, no new work.
func_801412A8 198 ins x 138 = 27,324 close=29/110 since Phase 24. Matched from 1 of 31 stored
drafts + the §37/§124 alias.
WHY func_801412A8 LOOKED INTRINSIC (worth understanding — match_one is structurally blind to it):
the TU declares `extern int func_801412A8(int,int,int,int,int,int)` and its callers USE the return
(`param_1 = func_801412A8(...)`), while the byte-true definition is
`Prim_1412A8 *(Prim_1412A8 *, int, int, int, u16, u16)`. Narrow params cannot agree with an `int`
prototype and the no-prototype escape is illegal once a param promotes, so NEITHER side can move --
and the resulting byte difference is in the CALLERS, which match_one never compiles. The §37/§124
def-side asm-label alias decouples them: the TU decl keeps governing the call sites (codegen
untouched), the definition keeps its byte-true signature.
THEN PROPAGATION RETURNED 0/137 TWICE, both times a missing TYPE, not codegen:
family_remap's `_carry_macros` carries file-scope #defines but (a) NOT typedefs, and (b) is NOT
TRANSITIVE -- it brought addPrim_1412A8 and stopped, though that macro calls setaddr/getaddr and
getaddr casts to PTag_1412A8. Lifted Env_1412A8 / PTag_1412A8 / Prim_1412A8 + OT/getaddr/setaddr
into src/shared/engine_types.h (inside the include guard) -> 137/137, 0 failed.
MY ERROR, CAUGHT BY THE GATE: I lifted the typedefs but did not STRIP them from ov_SC01_077.c, so
they were declared twice and gcc-2.7.2 rejects a repeated typedef even when identical -- the lesson
already recorded at the foot of engine_types.h. R22 came back 139/140 with [FAIL] ov_SC01_077 (the
exemplar's own overlay). Stripped, re-verified, 140/140. A proper lift strips the source;
build_engine_types --strip does both and I did it by hand.
Also a measurement error worth recording: I checked whether the draft defined Prim_1412A8 with a
plain `grep -c` -- which matches inside `addPrim_1412A8` -- and briefly concluded the carry worked.
Substring false positive; the same shape as reading a `return` as a declaration.
VERIFIED: make clean && make extract-all && make check-all -> 140 passed, 0 failed of 140.
Fleet 12432941 -> 12483035 instr (+50,094 -- EXACTLY the two giants x138); fn-count +276;
instr-weighted 94.5% -> 94.8%. audit-digest OK. 0 NON_MATCHING (G4).
THE RULE THIS BUYS: re-measure a wall before respecting it, and SCAN every stored draft rather than
sampling (my first pass checked 8 of 31 and reported "closeness 40" for a function whose MATCH was
in the 9th). Four minutes of re-measurement was worth 50,094 instructions.
Measured the h_exact free pool from the bytes rather than trusting the frontier report's
numbers (R14 — its whale claim was 3/4 wrong: it said the whale was open in all four SC07
overlays; three were already banked and I closed the fourth earlier this session).
MEASURED: 215 open function-instances / 8,763 instructions are byte-identical (h_exact,
including reloc payloads) to an already-matched function. ONE class is 86% of that pool:
func_801758FC — 55 ins, same address in all 138 overlays, matched in ov_SC01_000 only,
OPEN in the other 137 => 7,535 instructions.
h_exact means identical INCLUDING jal/lui/%lo reloc immediates, so the matched body compiles
byte-identically at every member with NO remap (dedup_extend's correctness argument, §14).
dedup_propagate --addr authored it once as DEFINE_func_801758FC() in engine_core.h and
instantiated it at all 137 open sites in address order.
[ OK ] 138 overlays byte-identical after propagation; 1 new group in config/dedup.us.yaml
VERIFIED: make clean && make extract-all && make check-all -> 140 passed, 0 failed of 140.
Fleet instr 12411467 -> 12419002 = +7,535 EXACTLY; fn-count +137; instr-weighted crosses to
94.5%. distinct-code unchanged BY DESIGN -- the class was already matched in ov_SC01_000, so
the 137 add fleet instructions but no new DISTINCT function. audit-digest OK. 0 NON_MATCHING.
Note this function had been sitting in the stored-draft backlog for ov_SC06_030 and
ov_SC07_010 and re-gated "no" earlier tonight -- because gating a DRAFT is the wrong move for
an h_exact class. The right move is propagating the already-MATCHED body. Same function, two
routes, and only one of them is free.
Remaining free pool after this: 78 instances / 1,228 ins across 32 classes.
Applied the def-side asm-label alias transform to all 971 staged member drafts (of 997; the rest
had no func_<ADDR> definition head) and gated them: 192 source files changed, ~5,985 insertions.
R22 clean-fleet 140/140 AFTER reverting ov_SC06_030 (below).
METRICS, AS MEASURED — one of them moved the WRONG WAY and I cannot yet explain it:
fn-count 96.32% -> 96.46% (+483 fns)
instr-weighted 94.4% -> 94.4% (+2,990 ins)
distinct-code 89.3% -> 89.2% (78,025 -> 77,952 uniq, -73)
A revert of ONE overlay to HEAD cannot lose 73 distinct functions, so something else is going on.
LEAD (NOT CONFIRMED): progress.py's definition scanner records the identifier immediately before the
paren (SIG at tools/progress.py:423), so an alias definition `void aF80146A6C(...)` is recorded as
`aF80146A6C`, not as func_80146A6C. That same scanner's docstring documents this exact blindness for
K&R defs, where it "silently erased ~190k banked instructions". BUT that lead does not explain why
fn-count ROSE while distinct-code FELL — they should move together under a pure naming artifact.
DO NOT treat the alias harvest's yield as established until this is resolved: the bytes are proven
(R22), the ACCOUNTING is not.
ov_SC06_030 REVERTED: `D_800AF648' undeclared in func_8017E120 — a draft that gated fine broke once
the REST of the harvest landed in the same TU (its declaration presumably displaced by another
banked draft's preamble). SECOND instance today of "per-binary acceptance is not a fleet claim"
(§61), after ov_SC07_010. In a WIDE harvest it is not even a per-TU claim, and only the clean-tree
R22 catches it. The narrow single-family run (138/138) was clean precisely because it was narrow.
Family 0x80146ab4 (18 ins, x138, PURE) had been failing 0/138 with `conflicting types for
func_80146A6C` — 208 of the ~398 conflicts in the sweep residue, its single dominant blocker.
DIAGNOSED BY READING THE DRAFT, after three levers were eliminated by measurement:
draft def : void func_80146A6C(s16 a0, s32 a1, s16 a2, s16 a3, u16 a4, s32 a5, s32 a6)
TU decl : extern s32 func_80146A6C(s32 a0, void *a1, s32 a2, s32 a3, s32 a4, s32 a5, s32 a6);
The NARROW PARAMS are the wall: C's default argument promotion means s16/u16 cannot agree with an
s32 prototype, and the `()` no-prototype escape is ILLEGAL precisely when a param promotes. Neither
declaration side can move.
- cast_call_sites: already on by default; wrong axis (fixes CALLEE decls, not the def's own).
- --normalize-self-decls: 0 banks + non-neutral reverts; wrong axis (the target's decl in callers).
- --fix-def-sig: measured 0/138, error UNCHANGED — it cannot reconcile a promoting param at all.
THE ESCAPE (§37/§124, S33-proven on func_80147364 — definition (u16,u16) vs 4,046 fleet decls,
banked x137 first try; 1,725 in-tree precedents): give the DEFINITION a private C identifier and
bind the emitted symbol with a GNU asm label, so the TU's declaration never meets the definition and
its type becomes irrelevant. Zero blast radius on every caller; byte-neutral by construction.
void aF80146A6C(<byte-true params>) __asm__("func_80146A6C");
void aF80146A6C(<byte-true params>) { ... }
RESULT: 138/138 banked, ~2,484 instructions, ZERO agent tokens. R22 clean-fleet 140/140.
.run/alias_defs.py applies the transform to a staged draft set.
NEXT: this is a CLASS lever, not a one-family fix — generalise it across the remaining sweep residue.
Families that returned 0/N before the 895-type lift now bank: 97 member-matches across 137 families
(1,138 failed; skipped 186 STRUCT-class by design, 106 unresolved-immediate, 6 not-stub).
R22 clean-fleet 140/140. Fleet 94.2 -> 94.3% instr / 88.9 -> 89.1% distinct / 96.29 -> 96.32% fn.
RESIDUE PRICED FROM THE SWEEP'S OWN .classified.txt PAYLOADS, not inferred: in the 400 most recent
failure records, 133 are genuine DIFF and the clear majority are `conflicting types for <sym>` —
the §103/§20 extern-conflict class, across ~12 overlays. That confirms S1b (wire reconcile_tu /
cast_call_sites into the --hseq path) is the correct next lever, and it is now justified by
measurement rather than by the plan's projection.
Method note worth keeping: those per-member diagnoses have been written on every sweep run for a
month and were never read — including by me, until after I had spent two probes and a manual
--stage-only round rediscovering one of them. Every remaining task now starts by reading the payload.
The free-sweep "wall" was a C parse error: a remapped member body names the EXEMPLAR's TU-local
types, which are undeclared in the sibling's TU, so gcc-2.7.2 parses the declarator as an expression
and dies before ever reaching codegen. extract_unit does carry typedefs, but only ones immediately
preceding the function in the preamble — types declared elsewhere in the exemplar's TU are missed.
Rather than patch the scanner per-family, remove the class: lift every liftable local type into the
shared header once. 895 types lifted, 6,196 local definitions stripped across 1,259 files.
R22 clean-fleet 140/140.
EXCLUDED s8/s16/s32/u8/u16/u32/f32/s64/u64/f64 — lift_types classified those common.h scalars as
liftable and lifting them would have been actively harmful. The tool's own visibility guard kept 8
local defs in src/ov_SC01_077/ov_SC01_077_o0.c, which does not include engine_types.h (stripping a
type out of a TU that cannot see the replacement DELETES it, and the link error that follows names
an unrelated data symbol).
Mechanism proven before scaling: lifting just 3 types took 0x801833f0's family from 0/6 to 6/6.
Fleet 96.17 -> 96.21% fn-count / 93.8% instr / 88.0% distinct; dedup 1909 -> 1910
groups, 0 failed, C1 241216/241216. R22 clean-fleet: 140 passed, 0 failed of 140.
The head is now 5/5 classes, 18,545 templatable ins, all banked this session from
a standing start of 0.
func_801466F0 had sat since S6b behind THREE separate blockers, each of which
looked sufficient on its own to explain the failure:
1. Its definition is under a §37/§73 ASM-LABEL ALIAS (`aF801466F0` in C, bound to
the real symbol by `__asm__`), and dedup_propagate.find_site anchored its head
regex on the literal `func_<ADDR>` — structurally blind to the form, returning
None, which every caller reads as "not matched". Now reuses
family_remap._alias_decl_for rather than growing a second matcher (R33).
2. That matcher was itself blind to the WRAPPED (multi-line) declaration — the
§134 shape, third tool. Fixed by matching over the joined text and mapping the
offset back to the decl's FIRST line (extract_unit carries from there).
Regression control: the single-line form still resolves. Fleet census after:
2,768 of 2,768 alias sites resolve, 0 missed.
3. Its record type was a draft-local typedef, so the body failed
compiles_standalone. Lifted Rec801466F0 to src/shared/engine_types.h INSIDE
the include guard (the SESSION-19 double-include note) and switched both the
macro and the exemplar to it — byte-neutral, gate-proven.
Probed on ONE member before the fleet run: byte-identical 9052dc0e first try.
MEASURED, NOT INHERITED (R37): the S6b note frames the alias-regex gap as a CLASS
of missed work. It is ONE function — 91 distinct alias decls fleet-wide, the
per-line matcher resolved 90. Recording it so a future session does not scope a
phase against a class that does not exist.

- a MULTI-LINE comment halts the preamble backscan -> fix the tool (cdecl._mask)
- a draft-local `struct Tag {…}` -> switch the exemplar to the SHARED type
- a file-scope `static inline` helper -> hand-author, EXCLUDE the source overlay
The third is the sneakiest: gcc-2.7.2 accepts implicit function declarations, so
the extracted body PASSED compiles_standalone with the helper undeclared and the
miss surfaced only as a whole-binary byte DIFF 137 gates later. Instantiating
that macro in the SOURCE overlay is a duplicate definition (its file-scope helper
is still there), so the shape is `--source-overlay X --binaries <all-but-X>`;
`--binaries` alone removes the source from the scan pool and errors.
TOOL BOUNDARY: once a group's members are DEFINE_func_*() sites, dedup_propagate
cannot extend it (find_site never returns a `def`). dedup_extend is the tool for
an already-macro-ized group — and `dedup_extend --check-only` across ordinary
overlays is a cheap fleet-wide wiring census (measured: exactly 1 group per
overlay, so no hidden backlog).
MEASURED, NOT INHERITED (R37): the S6b note frames _alias_decl_for's single-line
regex as a CLASS of missed work. It is not — 91 asm-label alias decls exist
fleet-wide, the regex matches 90, and the single miss is func_801466F0. Worth
3,288 ins, but a one-function fix. Correcting the expectation so a future session
does not scope against it.
Fleet 96.06 -> 96.10% fn-count / 93.7% instr / 88.0% distinct; dedup 1907 -> 1908
groups, 0 failed, C1 240807/240807. R22 clean-fleet: 140 passed, 0 failed of 140.
func_8012A598 (3,288 templatable ins) was being written off as CARRY-FIXABLE.
It took TWO fixes; either alone leaves it skipped.
1. TOOL (R33) — find_site's preamble backscan. The SESSION-18 fix handled blank,
`//`, and SINGLE-LINE `/* … */` lines, but a MULTI-LINE block comment still
halted the walk: its middle lines start with `*` and its last line ends `*/`
without starting `/*`. So the three externs above the body were dropped and
the body then failed compiles_standalone on now-undeclared data. This is the
§134 multi-line-blindness class — S6b fixed the identical shape three times in
family_remap (D1/D2/D5) and this copy was never reached.
Fixed by deciding skippability on `cdecl._mask` — the project's ONE masking
oracle — instead of on line syntax: it subsumes every comment form at once and
cannot be fooled by a `/*` inside a string, with an R32 assertion on the
length-preservation invariant it rests on. Strictly monotone (it can only
carry MORE preamble), and dedup_propagate is a byte-gate feeder, so a bug here
can fail to bank but never falsely bank.
2. EXEMPLAR — the body also declared a draft-local `struct BigCopy164` tag, which
the tool refuses by design (two macros defining one tag would redefine it in a
single TU). The shared `struct BigCopy` (engine_types.h L312) is the identical
layout and is ALREADY used this exact way at engine_core.h:16158, so switching
the exemplar to it is byte-neutral and drops the alias too.
Probed on ONE member before scaling (R37/S29): byte-identical 9052dc0e first try;
then 138 overlays byte-identical.
PROPAGATE head accounting after this: 7,398 of 18,545 ins banked (func_80147364
4,110 + func_8012A598 3,288). Still open, each with a NAMED cause and none yet
diagnosed against a build: func_8012f274 (3,973, dropped), func_8016ba68 (3,886,
4/138), func_801466f0 (3,288, the S6b D4 wrapped-alias gap).
Continues the S11 lane. Fleet 96.01 -> 96.06% fn-count / 93.6 -> 93.7% instr /
88.0% distinct; dedup 1905 -> 1907 groups, 0 failed, C1 240669/240669.
R22 clean-fleet: 140 passed, 0 failed of 140. 0 NON_MATCHING (G4).
EXTEND (SC07): the 16 volatile-blocked DIFF slots banked on retry after the
data asm-label alias -> lane total 31/36.
PROPAGATE head, measured rather than projected. .run/s8_lag.json re-split: the
checkpoint's "45 classes / 20,837 ins" is really 5 classes carrying 18,545 ins
(89%) and 41 carrying 2,316. Per-class outcome:
func_80147364 30x137 = 4,110 BANKED x137 (definition-side asm-label alias)
func_8012f274 29x137 = 3,973 DROPPED — byte-diverges in ~130 overlays
func_8016ba68 29x134 = 3,886 4 of 138 banked; excluded from ~130
func_8012a598 24x137 = 3,288 SKIPPED, cause NAMED by the tool
func_801466f0 24x137 = 3,288 no source found — the S6b D4 gap, still open
func_80147364's byte-true definition is `(u16, u16)` while 4,046 fleet decls
say `(u16, s32)`. u16 is a default-promotion type, so the `()` no-prototype
escape is ILLEGAL (the documented gcc-2.7.2 dead-end) and conforming the decl
would change caller codegen. The DEFINITION-SIDE asm-label alias gives the def
a distinct C identifier while emitting the real symbol -- zero blast radius on
every caller. Probed on ONE member first (1 build, not 137 -- the S29
discipline): byte-identical 9052dc0e first try; then 137 overlays clean.
In-tree precedent for the form: 1,725 files.
MEASURED NEGATIVE, recorded not buried: `dedup_propagate --recover` banked only
4 of 138 on func_8016ba68 and dropped func_8012f274 entirely (137 [exclude]
lines). The caller-extern reconcile that is 16/16 lifetime ON DRAFTS does NOT
transfer to PROPAGATION of these two. Cause not yet diagnosed -- probe one
excluded overlay's build output before any further attempt (§136a), do not
re-run the lever hoping.
NAMED NEXT (cheapest first): func_8012a598 skips on `missing file-scope extern
(CARRY-FIXABLE): D_801151D4, D_80126DB8_a, D_80127504` -- the SESSION-18
preamble-backscan class. Its body is 2 statements and `struct BigCopy` is
ALREADY in the shared engine_types.h (L312) with the identical statement already
macro-ized at engine_core.h:16158, so a hand-authored macro (the func_80147364
path) should take it x137 for ~0 tokens.
Process errors recorded in CURRENT_PHASE.md, all three one mechanism -- the
signal sampled is not the thing waited for: (1) a `nohup CMD &` wrapper's exit
read as the fleet check finishing (it stood at 63/140); (2) a corpus.stubs probe
mid-rebuild, which R32's coverage assertion refused rather than answer wrongly;
(3) CORRECTION to the S10 checkpoint's own rule -- `pgrep -x make` is right for
one make and WRONG for a campaign of sequential makes (it fired in a gap and
reported a live campaign done), and `pgrep -f <pattern>` SELF-MATCHES so that
waiter can never exit. Wait on the campaign process or `treelock.sh --status`.
- S8-3 (23 fresh x10-99 families, 121-328 ins — the hardest band this session): draft 16/23 ->
capture (1 PLUMBING / 6 DIFF) -> reconcile 1/1 -> redraft 6/6 => **23/23 (100%)**.
Propagated 206 + 81 = 287 member-matches across 80+54 overlays. R22 clean-fleet 140/140.
FLEET 95.97% fn / 93.4% instr / 87.5% distinct (77,404 uniq); dedup 1905/0; 0 NON_MATCHING.
- §136b CLOSES AT 15/15 — no function ledgered "genuine byte-DIFF" survived a redraft, all session.
- §137 (NEW, the session's most reusable result): REGALLOC-PERM — a clean 2-register swap — is a
TWO-COMPILE ARITHMETIC PROBLEM. global.c:allocno_compare ranks by floor_log2(R)*R/L*1e4*size;
read R and L out of `cc1 -dl -dg` for BOTH contenders AND their ranked neighbours to get the
admissible priority WINDOW, then place a zero-byte `__asm__ __volatile__("" ::"r"(v))` so L lands
inside it. func_801833F0: contenders ONE unit apart (1297 vs 1296), window (1228,1296), five
placements probed, only L=219 -> pri 1232 worked. R and L are FORCED BY THE EMITTED CODE (L is
recomputed post-sched1), which is exactly why source-reordering is a dead end for this class.
Converts a class the permuter banked 0 from all session into a deterministic calculation.
Companion: floor_log2 makes ref-count a STEP function (5/6/7 refs are worthless, you must reach 8)
— func_8017EFA8 closed 30 register-name mismatches by taking a pseudo 4 refs -> 8 with a dead read.
- §136j — the failure MIX FLIPS WITH SIZE: <=120 ins fails ~70% on declarations; 121-328 ins fails
86% on genuine codegen. Budget reconcile for the small band, redraft for the big one — and do NOT
read 70% on a big-function wave as a broken pipeline; that is the expected shape.
- §137a — a gate verdict has a TIMESTAMP. Two "DIFF" ledger entries were STALE (draft rewritten 28
min after the gate ran, never re-gated); both were already byte-perfect. Compare verdict time to
draft mtime before redrafting. Plus two offline oracles an agent built: a FULL RELOCATION RESOLVE
(catches wrong jal/%hi/%lo targets that match_one's mask hides) and a COLLATERAL CHECK (whole-TU
objdump with/without splice). Together they discriminate all three causes of "match_one says MATCH
but the overlay SHA differs" without running make.
- §136f addendum — the collider is often an already-banked SIBLING BELOW the splice; locate it by
arithmetic (draft grows the file N lines, so TU line L reports at L+N).
- cookbook-index 380 -> 382 sections.
- WAVE 4b BATCH 1 (37 volume-lane targets, 10-19 members, <=60 ins; wave 4a's §136 idioms promoted
into the drafting prompt per the measured 83%->93% law): 50 agents / 4.35M tokens / 32 min ->
34 claimed MATCH -> gate BANKED 32 -> family_sweep propagated 365 member-matches / 4 failed
across 84 overlays (3 STRUCT skipped by design). 397 function-instances from 37 targets.
- §136b — THE FINDING THAT CHANGES THE BACKLOG: all FOUR functions wave 3 ledgered as "genuine
byte-DIFF" BANKED on redraft. The recorded causes were never codegen:
func_801845B0 a branch to the EPILOGUE misread as an inner early-exit -> the whole tail was
hoisted out of its enclosing if (control-flow misread)
func_80184A94 a declaration conflict on a symbol declared BELOW the splice point; closed by
copying an already-banked family sibling's decl forms verbatim (§71)
func_8017BEBC the cached Ghidra seed was an ENTIRELY DIFFERENT body and the prior draft
followed it; the .s was the only usable source
func_8018480C re-derived clean
=> a DIFF verdict describes THE DRAFT THAT WAS ATTEMPTED, never the function's matchability.
Never retire a target on one; route it to REDRAFT. And re-GATING an unchanged draft is not a
retry — which is exactly why wave 4a's 3 DIFFs stayed stubs through this gate (same bytes
resubmitted); they still owe an actual redraft and are now likely winnable.
Corollary: backlog entries carrying an old closeness/class are stale by construction (P29
measured 77% of stored drafts decayed) — re-verify before valuing one.
- The wave-4b prompt handed each retry its prior verdict EXPLICITLY LABELLED "a data point, not a
verdict — re-derive from the .s". Every retry agent did exactly that and refuted it.
- R22 clean-fleet 140/140 (fourth time this session). FLEET 95.63% fn / 92.8% instr / 86.3% distinct
(76,499 unique fns); dedup 1905/0; C1 240496/240496; 0 NON_MATCHING (G4).
- Orchestration: this batch's workflow script was GENERATED from the manifest files rather than
hand-pasted — transcription had already cost this session one dead launch (args-as-string) and
cost the prior session three agents' time (hand-typed _jr_* paths). Generate the artifact; do not
ask yourself to be careful. cookbook-index 371 -> 372 sections.
- RECONCILE LANE: all 7 PLUMBING failures FIXED and banked (329K tokens — ~13x cheaper than the
drafting wave's 4.44M). Propagated +76 member-matches / 0 failed across 51 overlays.
Wave 4a final: 30/33 heads (91%) + 327 members = 357 function-instances from 33 drafted targets.
- THE CAPTURE CLASSIFICATION WAS EXACTLY PREDICTIVE: all 7 PLUMBING banked, all 3 DIFF stayed stubs
(func_8017E978 / func_80184494 / func_80184960 -> redraft lane, their C is wrong). That is what
makes the ~10-build capture step worth running before any reconcile fan-out. The lane is now
19/19 across three waves.
- EVERY reconciled draft had a HIDDEN SECOND CONFLICT cc1 never reached (it reports only the first)
-> "grep the whole TU in one pass" must be in the RECONCILE prompt, not just the drafting prompt.
One agent additionally assembled the spliced TU and masked-compared its function IN TU CONTEXT
(67/67) — proving the casts byte-neutral in situ, not merely standalone.
- NEW HAZARD, agent-surfaced (§136a corollary): an agent chose a SHARED scratch path, a concurrent
agent overwrote it, and its verification silently compiled ANOTHER agent's TU and returned a
meaningless rc=0. It caught the swap only because the emitted .s lacked its own function. A shared
scratch path yields a CONFIDENT WRONG VERDICT, and no tool fix reaches it — the choice happens
inside the agent, so the PROMPT must mandate a process-unique path. This is the Phase-28
match_one fake-isolation defect recurring one level up.
- R22 clean-fleet 140/140 (third time this session). FLEET 95.52% fn / 92.7% instr / 86.1% distinct
(76,273 unique fns); dedup 1905/0; C1 240496/240496; 0 NON_MATCHING in any default build (G4).
- .run/s7_extra.txt: wave 4a's idioms compiled into the wave-4b drafting prompt (the promotion that
measured 83%->93% between waves 1 and 2).
- WAVE 4a (T6, the 33 high-value B-shape families, 61-120 ins / >=10 members):
33 targets, 46 agents, 4.44M tokens, 29 min -> 29 claimed match_one MATCH.
Whole-binary gate BANKED 23/33 (70%); family_sweep --hseq --band all propagated
251 member-matches across 69 overlays (13 failed, 4 STRUCT skipped by design).
Total 274 function-instances from 33 drafted targets.
- R22 clean-fleet: make clean + extract-all + check-all -> 140 passed, 0 failed of 140.
make report: fn-count 95.49% / instr 92.6% / distinct 85.9% (76,180 unique fns);
dedup 1905 validated / 0 failed; 0 NON_MATCHING in any default build (G4).
- COOKBOOK §136 (R30, distilled in-session from 25 banked functions' index-gap reports):
the wave's finding is that in the 60-120-ins band most "regalloc residuals" are decided
by HOW MANY C LOCALS AND AT WHAT SCOPE, not by register pins (local-alloc.c:472 promotes
any pseudo with REG_N_DEATHS>1 to a global allocno). 19 byte-verified idioms: 6 splitting/
merging rules, 6 type-form rules, 5 scheduling rules refining §135-2/§135-4, 2 declaration-
surface rules. One case explicitly REFUTES the pin as the lever for a redundant copy.
cookbook-index regenerated 364 -> 370 sections, --check green.
- TWO SELF-CORRECTIONS (R37/R14), both caught before they could mislead sizing:
(1) I wrote the tier split from the workflow's by_tier, which counts CLAIMED matches (29)
not banks (23). Derived per-function: Opus-direct 10/14, Haiku-direct 3/8, Opus
escalation-after-Haiku-miss 10/11. The operative number is the 10-of-11 rescue rate;
on this band Haiku is triage, not a substitute (it is == Opus only at <=50 ins).
(2) The gate printed "1/1 banked FAILED: func_X" on single-draft groups (the known
double-list artifact) -> bank set DERIVED from corpus.stubs instead. Totals agreed.
- TOOLING: the wave scripts now parse args-as-string and assert Array.isArray, so the
roadmap's standing "args must be an array" gotcha cannot silently kill a future wave
(it killed wave 4a's first launch in 60ms with 0 agents).
- tools-health green + fail-closed before matching (corpus+resident 0 PHANTOM/0 TRUNCATED,
audit-binaries 140/140 citizens, cdecl, report/lint/dedup).
- 15 targets (11 fresh Haiku + 4 gate-failed reconciles on Opus), 15 agents, ~0.74M tokens.
Gate banked 14/15 (93%) vs wave 1's 20/24 (83%); ALL 4 RECONCILES BANKED.
Propagation +328 members / 0 failed / 76 overlays. R22 clean-fleet 140/140.
Fleet 95.23% fn-count / 92.1% instr / 85.0% distinct (phase opened 92.00 / 87.5 / 78.0).
- THE 83->93% CAME FROM THREE FIXES, ONE PER WAVE-1 FAILURE (the S27 finding reproducing):
(1) args pasted from the DERIVED manifest, never typed — all 30 paths verified on disk first;
(2) blocker-capture BEFORE the reconcile fan-out (S29 law: agents cannot run the gate, so a
match_one-MATCH draft dying on `conflicting types` reads to them as a codegen wall) —
each got the exact symbol+line plus the two byte-neutral levers;
(3) wave-1's Opus DISCOVERIES became wave-2's Haiku INSTRUCTIONS (ori-vs-addiu unsigned
destination; store-sinking scheduler order).
- THE RECONCILES OUT-DIAGNOSED MY CAPTURE: func_80189B78's error named ONE symbol; the agent found
SIX invented prototypes, two AFTER the splice point where cc1 had not yet reached — all fixed by
copying the TU's decls verbatim + casting at the call site, zero bytes changed. func_8018584C had
lever (A) blocked in BOTH directions (the draft must also compile standalone for match_one) and
closed with the DATA form of the asm-label alias. func_80180A4C was one character class (s32[] vs
the TU's u8[], declared 11 lines after the splice point).
- Carried: func_80189C4C (the one agent that returned no structured result; gate refused).
- func_8017E934 (ov_SC05_001, 29 ins x65): hand-drafted off the .s, match_one MATCH first try,
whole-binary gate byte-identical, propagated 64 members / 0 failed across 63 overlays.
- That makes the B-shaped lane 3-for-3 one-shot (func_8017CDD8 17ins, func_8017CE7C 16ins,
func_8017E934 29ins) for ~0 agent tokens = 330 member-matches from 62 instructions of C.
- THE POOL (derived from the regenerated map): 36 families / 28,829 templatable ins that are
kind=modal (NO member matched anywhere, so no sweep could ever reach them) with >=20 members
and <=60 ins, non-jr. NOT ONE exemplar is in ov_SC01_077 — they are invisible to exactly the
two habits this phase already corrected (the ov077-source default and --band substantial).
- The calibrated recipe, now the wave prompt: read the .s as ground truth (a cached Ghidra-C seed
was measured this session decompiling a DIFFERENT body) -> conform every callee decl to what the
TU already says (the PLUMBING class: standalone-MATCH C is gate-REJECTED as `conflicting types`
when it redeclares a callee the TU defines as (void)) -> match_one -> whole-binary gate.
- R22 clean-fleet 140/140; fleet 94.96% fn-count / 91.9% instr / 84.7% distinct.
- A: frontier regen at HEAD (sigs + family_hseq) before pricing anything (R35). Also the reason
it was needed: .run/hseq_verified.*.txt has accumulated 22,841 files across every sweep ever
run, so any per-family analysis globbing them over-counts; the regenerated map derives state
from sigs + corpus.stubs (R33), which is the authority.
- B / THE FINDING (third §133-class miss in a row): the S29 checkpoint's structural signal
"after S2 the x138 era ENDS — those are the last two crackable fleet-wide families" — the stated
TRIGGER for the phase close — is wrong. Two fresh-crack families with >=126 members were open:
0x8017cdd8 ov_SC02_039 17 ins x 142 members PURE
0x8017ce7c ov_SC03_114 16 ins x 126 members IMM
Both kind=modal (NO member matched anywhere, so no sweep could reach them) and neither exemplar
in ov_SC01_077 — invisible to exactly the two habits this phase already corrected.
- Both hand-drafted off the .s, match_one MATCH on the FIRST try, ~0 agent tokens. First gate
attempt failed PLUMBING (not DIFF): the draft declared `extern void func_8017CFCC(s32 a0)` while
the TU DEFINES `void func_8017CFCC(void)` — the target passes $a0 only because the caller's
incoming argument still sits in the register (loose typing). Byte-true C calls it with no
argument; re-verified MATCH, gated byte-identical, propagated 266 members / 0 failed / 118 overlays.
- R14 on the seed: the cached Ghidra-C for func_8017CE7C decompiled an entirely DIFFERENT body
(three calls absent from the asm). Reading the .s is what made it one-shot.
- R22 clean-fleet 140/140. Fleet 94.88->94.96% fn-count, 91.9% instr, 84.6->84.7% distinct.
- ONE root cause, four faces (cookbook §134): extract_unit's preamble scanner reads C
one line at a time, so every construct that WRAPS was misread.
D1 the {-guard fired on a documentation comment mentioning a brace -> carry truncated
mid-comment -> `parse error before 'the'`.
D2 _def_head_at's "param list continues -> ANSI definition" fallback accepted a WRAPPED
DECLARATION as a definition head -> a 16-line fragment with no body, closed by a brace
pair inside a comment -> a silent 0/137 that reads exactly like a compiler wall.
D5 the backscan met a multi-line typedef's CLOSING line `} T;` first and stopped -> the
type never travelled -> `T undeclared` across 17 families / 24,332 templatable ins.
(The code comment claimed they "route through the engine_types.h lift"; measured, they
routed nowhere.)
D4 wrapped __asm__("func_...") alias invisible to a single-line regex — MEASURED (1 exemplar,
3,288 ins, second blocker behind it) and deliberately NOT fixed; it now returns None so the
sweep reports a VISIBLE skip instead of 137 silent failures (R32).
- Fixes: _def_head_at(ln, idx, more=()) lookahead (no-lookahead keeps the historical answer);
{-guard exempts comment-only lines + an R32 dangling-comment backstop; forward brace scan
counts over cdecl._mask (R33, one masking oracle); _typedef_block_start carries whole blocks.
- BLAST RADIUS (R14): extract_unit diffed vs the pre-fix tool over all 181 zero-crack exemplars
-> 157 byte-IDENTICAL, 24 changed, all in the intended direction.
- PAYOFF: D1+D2 +323 members from families that banked ZERO; D5 +417 incl. func_8012B77C 139/139
(8,062 ins) and func_80128C98 137/275. S6 total 1,582 members (pre-fix tool scored 842).
- R22 clean-fleet 140/140. Fleet 94.43->94.88% fn-count, 91.4->91.9% instr, 84.0->84.6% distinct.
- TELL worth keeping (§134): bimodal bank rates (57 all / 52 zero / 8 partial) are a TOOLING
signature, not codegen. Probe one member and read one compiler error before writing a family off.
