- tools/family_align.py (NEW module — classify_member's return contract untouched,
the remap_hseq silent-pass trap avoided by design): SequenceMatcher alignment
over FC.tok streams; li-cluster reconstructor (lui/lui+addiu/lui+ori/li-from-$0
chains, split-cluster absorb for the rs-changed addiu partner); verdicts
LEN-LI/LEN-NOP/LEN-JTBL/LEN-STRUCT/STRUCT-ALIGNED/PURE/IMM; aligned imm engine
mirroring imm_map_tier1 (ordinal deliberately out in v1)
- NC-1 verdict-equivalence 157/157 banked pairs — the NC caught two real gaps:
R-type non-shift sa diffs are STRUCT; registers tested BEFORE the reloc skip
(a reloc-slot word with a different register is STRUCT). NC-2 parity 21/21
- R37 PROBE REFUTED the planned mechanical driver before it was built: 0/26
LI-ONLY cards classify mechanically (regfields x19) — cousins are 0.85-similar
DIFFERENT functions; §168 law 1 re-derived by measurement; no driver written
- family_align re-scoped: its consumer is T8's LEN+N near-miss pile (draft vs
its OWN target = same function); reloc-vs-constant range discriminator parked
for T8. decision-log entry (R31)
- tools/plumbing_groups.py: derives the honest still-open pool from the classified
ledgers (R38) — '1,217 PLUMBING' collapsed to 237 (SELF 109 / CALLEE 48 / OTHER
48 / DATA 32)
- recover_integration: PER-GROUP ISOLATION (git-checkout binary TUs between groups
— one TU-stage edit was poisoning every other group's whole-binary gate with a
phantom shared error; per-group banked_from_source capture) + new stages
'macro-externs' (§121 draft-tier, via family_sweep.macro_def_sig_map, R33) and
'tu-scope' (§103 STU binary-tier, the sweep-only lever)
- the probe (ov_SC03_107): raw 0/14 -> root-caused (poisoning + stale seed
symbols; rtu_match MATCHes them — blind to reloc names, R34) -> symfix-first
-> 9/14 BANKED (64%)
- sweep finding (Law 3): the no-draft majority (ov_SC02_037 44/44, most of
ov_MAIN_012) had verdicts from transient sweep remaps never persisted — family-
lane fuel, not recovery fuel; the stored-draft class is consumed
- cookbook §173 (symfix-first / per-group isolation / verdicts-without-drafts);
index 518 green; R22 clean fleet 213/213; phase total 17 banked @ 0 agent tokens
- decision-log: the P31 re-charter entry (organize-before-grind; R37/R38/R39
ratified at gate-1) per R31
- harvest_verify.py: import guard — a bare import now RAISES loud instead of
running a full gate (CLI unchanged, verified both directions)
- sig-resident: bootstrap boundary artifacts fixed (fused +0 data word with
func_800CEDFC; func_800D33E0 dropped past a glued tail) -> ELF-seeded per the
S45 pattern, exactly 145 fns; true denominator confirmed 145 (progress was
right); audit-corpus 0 PHANTOM + 0 TRUNCATED; all three oracles agree
- family maps regenerated at HEAD commit:2161: 11,025 open non-main members
reconciles EXACTLY with 12,059 - main 1,034 (102 stale phantoms cleared);
adapt cards 704, aprop cards 204 (full emission)
- main fuel-gap finding: 2,001/2,002 main stubs already have cached Ghidra-C
(only func_80049600 missing) — the roadmap '0/2,096' note was stale
- tools-health OK (dedup 2,063/0; C1 254,521/254,521; audit-digest green)
The §172a/§172b tells + repaired instruments swept over all 892 open near-misses:
- 33/95 stored drafts re-verified MATCH and banked through the whole-binary gate
(aprop_symfix caught 40/108 carrying stale seed symbols before gating — §171 at scale)
- 19/20 hand/mech fixes banked: four pure lhu<->lh s16 flips; the lhu+sltiu->lh+slti
shared-global quadruplet (D_80126B5E/B66/CB0, D_80126CB0 are s16 FLEET-WIDE); one xor-eq
rewrite; 11 per-location literal swaps (mask/threshold constants from sibling binaries)
- 1 refusal (func_8017EE78) stays as redraft fuel
Stubs 12,111 -> 12,059. Fleet 95.3% instr / 90.0% distinct / 96.68% fn-count.
Veins mapped for next waves: ~400 LEN+N drafts, 13 ambiguous-symbol, 7 multi-literal.
Audit ledger: .run/c294/audit_results.json (classifier derives from match_one's own sig).
The crack was NOT achieved; the wall is now mechanism-complete instead of inferred:
- caller-save.c setup_save_areas DISCOVERED as a second never-referenced-slot producer:
eager 4-byte areas per call-clobbered hard reg carrying a call-crossing pseudo at ANY
reload iteration (-fcaller-saves is on at -O2), emitted code or not.
- Alignment math corrected: alter_reg slots 8B (align -1), save areas 4B (align 0).
- The whole-binary gate run on v_best/v_dialfree for the FIRST time: both rejected —
the standalone NEAR-2/NEAR-25 verdicts are faithful, no TU-state leak.
- 200-variant randomized structural sweep: swapped-arm recomputes are the ONE dimension
that moves vars upward (cse does not merge the swapped select) at ~1:1 real-code cost;
four coincidental vars=256 hits, all heavy-drift.
- Proof: cross-jump cannot delete slot-bearing code (identical-offset requirement) —
the last no-residue mechanism branch closed by argument, not probe.
- Inline forms collapse the chain 246->209 ins: the bytes REQUIRE textual macro repeats.
- cc1 flag axis (-fforce-addr/-fno-force-mem/-fno-caller-saves/-fno-schedule-insns):
vars=224 invariant.
Idioms delivered (Drew's second ask): §172 v2 (complete frame-residue model: producers,
alignment, orphan rule, the three-layer canonicalization wall with its honest bound) +
§172a (the lhu/lh typing tell: movhi=lhu copy vs extendhisi2=lh promotion, the double-load
signature; the macro-vs-inline tell: re-evaluated compares in arms = textually repeating
macros, load-bearing redundancy). The 0x801F1CD8/0x8017D290 family idioms were §171a/b.
Floor stays NEAR 2/246. Parked for P32 with the siege kit: tools/cc1_dumps.sh, the §172-v2
model, sweep_gen.py, the swaprepeat lead. ~240 cumulative refutations, each byte-grounded.
- tools/cc1_dumps.sh: run the pinned cc1 with -dr/-ds/-dj/-dc/-dl/-dg and count standalone
(use (reg)) insns in the .combine dump — each is one 8-byte never-referenced reload slot.
The NEAR-2 residual = 12 such orphans vs the target's 16, now ENUMERATED pseudo-by-pseudo
instead of inferred from ablations.
- The orphan mechanism, exact (combine.c:10835 + mips.md force_not_mem): every short-mem read
is a movhi+shift-pair triple; the fold orphans its ashift temp iff the HI reg carries an
extra HImode use and the death-note walk hits a label/jump. Single-use loads never orphan;
the head can never orphan (walk reaches insn 0).
- The zero-code +4 factory is byte-refuted: 18 new probe families x 3 placements (s16
respellings, cast truncations, <<16>>16 factories, placement sweeps, loop t/n, dossier-file
re-sweep) all land at vars=224-same-bytes or drift. p_optr reproduces the target's exact
16-orphan frame at +7 insns — opacity that defeats cse equally blinds num_sign_bit_copies;
fold-const closes the tree level. Three canonicalizers, one wall.
- Dossier NOTES.md updated with the S50 ledger; backlog klass -> WALL(P32) for both names.
- NOT banked: no 0-closeness draft exists. The dial draft (NEAR 2) remains the floor.
Three carries a mechanical seed-body draft needs beyond the symbol rebase (cookbook §171b),
each found from one compiler verdict:
- DATA DEFINED INSIDE THE MEMBER'S OWN .s must be DEFINED, not externed — it vanishes with
the stub it lives in. Re-initialised with THIS member's bytes (the 0x801F1CD8 family carries
4 distinct 8-byte patterns across 42 members). Flat-byte-list initializers only; refuse the
rest rather than mis-initialise something the gate would reject unexplainably.
- SHARED TYPES the destination cannot see: MATRIX/SVECTOR live in engine_types.h, which md_*
TUs never include. `parse error before 'm1'` was the only thing between 4 of 9 members and a
bank. Carried brace-matched, vetoed by the destination.
- A POSITIONAL LITERAL MAP where imm_map_tier1 gives up: it refuses a value that also appears
at a non-differing slot (0x10 collides with the struct offsets), but the 8 differing slots
map 1:1 onto the C's call sites in order. Asserted ([C literals] == [seed slot values])
before substituting — that assert is the whole safety argument. 10/10 refused -> 9/9 banked.
- ROOT-CAUSE FIX: body_text matched `extern void func_X(...);` at column 0 and returned the
NEXT function's body — silently shipping wrong seed bodies, visible only as "no definition
after rename" skips. A definition is now confirmed by a `{` with no `;` before it.
R22 clean rebuild: check-all 213 passed, 0 failed of 213. Stubs 12,161 -> 12,111.
Fleet 95.3% instr / 90.0% distinct / 96.66% fn-count.
Final S50 state: 307 instances banked, stubs 12,468 -> 12,161, fleet 95.3% instr / 90.0%
distinct / 96.65% fn-count. R22 clean rebuild 4x, check-all 213/213 every time.
- tools/aprop_autodraft.py + tools/draft_prechecks.py: seed body + symbol_map + a MINIMAL
synthesized preamble. The seed's decl layer never travels — that layer is family_sweep's
dominant failure (331 of 458 S49 verdicts). 256 banked at zero agent tokens, against the
~20M the same work would have cost as a wave.
- Macro seeds (567 of 1196 members, all 3737 de-macroize) take the DEFINITION only; the block
stays the decl source. Pasting it whole measured 28% vs inline's 68% — func_8016AB6C's macro
is 1,891 lines of which 108 are the function.
- IMM is a second engine, not a wall: T2a's imm_map_tier1 resolves a per-location LITERAL like
symbol_map resolves a per-location SYMBOL. 131 of 275 IMM members resolve.
- draft_prechecks negative-controlled against ALL 205 banked drafts: zero false positives,
catches 39 of 67 known failures. That control found two bugs in the checks themselves —
C89 `f()` declares UNSPECIFIED parameters (not zero), and a member's own definition read as
a call to itself. Conservative by design: a pre-check that discards good drafts is worse
than one that lets a few builds fail.
- The A-prop pool is now priced exactly: PURE 437/37,376 ins, IMM 275/8,849, STRUCT 238/4,259.
- Cookbook §171a; SETUP rows; CURRENT_PHASE S50 FINAL checkpoint.
- The blocker was carried as "one missing file-scope extern gates 83 PURE members". Both
halves were wrong (R14): corpus.stubs says 4 open members, and D_801ED98C is a DEFINED
const Blk8 whose rodata lives inside the member's own nonmatchings .s — replacing the stub
deletes the data with it. gather_externs can carry an extern DECL, never a DEFINITION,
which is why it reported "no file-scope decl" for a symbol md_SC05_023 defines on line 114.
- Fix: paste typedef + const definition + body per sibling (data bytes verified identical
across md_SC05_024/025/028/029). 4/4 banked.
- aprop_symfix: new `local-only` class — draft-DEFINED identifiers that merely carry a
vram-looking suffix (Blk8_…, S8_…, L_call_…) are not stale symbols. Measured: that is every
non-clean case in the whole wave-7a/7b stored-draft residue, which holds ZERO stale-symbol
recoveries (a clean negative result — the defect was A-prop-specific).
- cookbook index regenerated (tools-health fails closed on a stale index — it caught §171).
- R22 clean rebuild: check-all 213 passed, 0 failed of 213. Stubs 12,445 -> 12,441.
- REFUTES §170's open hypothesis (batched cards concentrate members into one TU ⇒ §169
collision): 5-draft groups banked 5/5; 11 of 35 unbanked drafts were already one-per-TU;
and the two "concentrated" groups banked 12/12 and 10/10 once the real defect was fixed.
- The cause: a per-location data symbol carried out of the seed body unrebased. match_one
compares instruction ENCODINGS and is blind to a relocation's target NAME, so it scores
MATCH standalone and dies at link in the host TU. 24 of 24 concentrated failures, all 1:1
rewritable at one constant vram delta (0x4128).
- tools/aprop_symfix.py: audit + --fix, emits a gate_lane-shaped slate; deterministic and
build-free, so it runs BEFORE the gate. The R34 second oracle for the class match_one
cannot see.
- family_cousins.py --aprop-cards: members now carry sym_map, the explicit {seed -> member}
renames, read from the seed's C BODY (a matched seed has no .s of its own) vs the member's
.s. Two case-mismatch defects fixed while wiring it (sig lowercase vs splat uppercase).
- 23/24 banked. Stubs 12,468 -> 12,445. Fleet 95.2% instr / 89.9% distinct / 96.57% fn.
R22 clean rebuild: check-all 213 passed, 0 failed of 213. dedup 2,043/0.
- A-prop's true conversion is 87% (79/91); the 320 batched members are unblocked.
- Cookbook §171 + §170 struck in place; SETUP row; decision-log (R31).
- NEW family_cousins.py --aprop-cards + tools/wave/aprop_wave.js: lane A (1,700 open fns /
76,419 ins) had NO card type — cousin diffs are empty for h_seq-identical members, so the card
is a positional WORD diff vs the matched sibling, grouped BY FAMILY (one agent, N drafts).
Head cards: 13 families / 433 members, median TWO differing words each.
- calibration 9 batches / 108 members: 98 agent-MATCH (91%, best of any wave) -> 56 BANKED (57%),
~80k tok/banked fn vs 157k (cousin card) vs 400k+ (crack wave). R22 213/213 BYTE-IDENTICAL.
- HONEST GAP (R14): 91% agent -> 57% gate is the worst conversion measured; 14 groups banked 0.
Hypothesis TESTABLE not proven — family batching concentrates members per destination TU, the
§169 collision. Re-gate unbanked ONE PER TU before scaling the remaining 320.
- >=16 head diagnosed: 3 of 4 blockers are plumbing — the --band substantial default hid 5 of 13
families from every prior sweep; one missing file-scope extern (D_801ED98C) gates 56 PURE
members; dedup_extend is macro-only. Only func_8017C294 is a genuine crack.
- fleet 96.56% fn / 95.2% instr / 89.9% distinct; stubs 12,535 -> 12,468; dedup 2,043/0.
- cookbook §170.
- thresholds relaxed to <=6 blocks/<=16 tokens UNION edit-fraction <=0.20: cards 518 -> 721,
MIXED 310 -> 50 skeletons; the 753-ins func_8017BEBC (0.987 sim) became reachable.
- 59 cards -> 48 agent-MATCH (81%) -> 44 BANKED (92% MATCH->bank, 75% end-to-end), 6.9M tok.
- FINDING (the actionable one): 7b's bank rate crushed 7a's because it SPREAD 48 drafts over 35
destination TUs; 7a's failures were per-TU declaration collisions between sibling drafts.
Cookbook §169 updated with the spread law.
- R22 213/213 BYTE-IDENTICAL from clean; fleet 96.55% fn / 95.2% instr / 89.9% distinct;
stubs 12,584 -> 12,535; dedup 2,035/0.
- incidents 3 & 4 recorded: an agent wrote a TRACKED header (guard caught it, prose is not
enforcement); my own gate_lane filtered on the wrong key and printed 'gating 0 drafts' as a
result (R32 silent skip) — fixed with a coverage assertion that refuses to report 0.
- pilot 30 cards -> 25 agent-MATCH (0 refuted) -> 16 banked; 29 instances banked tonight
(89 incl. propagation); 2.7M tokens haiku-tier ~= 30k/banked instance vs a crack wave's ~75k.
- R22 213/213 BYTE-IDENTICAL from clean; fleet 96.53% fn / 95.1% instr / 89.8% distinct;
stubs 12,613 -> 12,584; dedup 2,029/0.
- R14 CORRECTION: a banked cousin usually does NOT propagate (2 of 8; cousins are byte-variant).
The card 'reach' column is cousin fuel, not dedup copies — priced wrong in my earlier framing.
- FINDING: the 9 gate failures are per-TU INTEGRATION (standalone-MATCH, host-TU-rejected),
clustered 5+2 in two binaries — the reconcile-ladder class, not codegen.
- TWO INCIDENTS (mine): an outer timeout tighter than gate_stage's own scaled timeout killed a
healthy 5-bank group mid-write AND orphaned its dedup_propagate child, which kept rewriting
src/ through a git checkout. Killed, inspected, reverted; the same 5 drafts banked 5/5 untimed.
Law: never wrap a self-timing tool in a tighter cap; kill process GROUPS, not pids.
- cookbook §169 (the lane + the three laws + the threshold sizing table).
- family_cousins.py --adapt-cards: per seeded-unit member, drift classified vs the seed
(LI-ONLY 27 / SMALL-EDIT 491 / MIXED 310 excluded); cards carry the seed C location + the
aligned diff blocks with the member's raw words + disasm (the new constant is readable in
the card). 518 cards / 1,101 instances / 23,820 ins; 514 haiku-band.
- tools/wave/adapt_wave.js: the EDIT-contract wave (crack_wave contracts preserved: per-agent
dirs, sha1-last, UNVERIFIED != refuted); symbol surface from the TARGET .s; haiku<=60/sonnet.
- regen chain absorbed the 48 lane-A banks (A-prop open ins -6,475 == the report's instr
delta exactly — two independent derivations agree); pilot slate .run/wave7a_pilot.json (30).
- R37: pilot before scaling to the 518-card pool.
- FINDING (Drew's smell, byte-verified): the '4,513 unique singletons' picture is substantially
an h_seq exact-hash artifact — 86/120 near-pairs in the 0.85-0.99 band differ by PURE
insertion/deletion (li-expansion tell in 25). Specimen: ov_SC06_010:0x8017bebc (753 ins,
'singleton') is 0.987-similar to a MATCHED fn in the same binary.
- NEW tools/family_cousins.py: distinct open skeletons -> shingle index -> >=0.85 union-find ->
matched-seed attachment -> .run/family_cousins.json + docs/family-cousins.md. R32 BOTH ways
(independent stub recount fails loud on a stale map — negative-control-proven; partition
assert). Reproduced the probe within +-1%; totals EXACT (11,627 inst / 584,448 ins).
- Unit table: A-prop 197u/68,729ins · seeded 418u/50,422 · cousin-multi 1,552u/249,799 ·
cold 3,240u/215,498 — the genuinely-unique tail is 37% of the remainder, not 90%.
Main's 'structurally barren' HOLDS at the similarity tier (94% mass <0.70).
- --targets wave slate: .run/wave7_targets.json = 40 targets / 33,304 unit ins (+33% vs
family-ranked), 9 resolved seed C paths, size-routed 2 haiku/20 sonnet/18 opus.
- LAWS (§168): a cousin is a SEEDED CRACK never a remap; rank waves by UNIT weight; discount
short-fn similarity. Byte-gate stays the sole arbiter (G3/P9).
- docs/family-hseq.md: this session's frontier regen (post-S48 propagations) rides along.
- cookbook §168 + SETUP inventory row (R16/R21/R30); CURRENT_PHASE S49 entry.
27 note-sets, 197 claims, one skeptic each, against a cookbook already holding
§162-§166 from this campaign:
NEW 5 · SHARPENS 43 · COVERED 126 · UNSOUND 23
byte-probed 92 · single-instance 75 · asserted 30
COVERED+UNSOUND: 57% (§164) -> 64% (§165) -> 76% (here). The duplicate rate
rises monotonically as the base grows. FIVE genuinely new laws out of 197
claims is the signal that the idiom well for this class of function is
approaching dry — future waves should spend tokens on cracks, not on mining
notes for idioms, and harvest only what a skeptic grades byte-probed.
The skeptics ran their own A/Bs this round. Best example: a crack agent claimed
"the source STATEMENT BOUNDARY decides whether the scheduler hoists a
far-consumed load". The vetter built that spelling and got .text BYTE-IDENTICAL
to the inline form, then swept eight POSITIONS and got five distinct objects —
showing the lever is statement position (the already-banked INSN_LUID
tie-break), not the boundary. Plausible mechanism, refuted by measurement, true
lever named in its place.
46 entries banked as §167-01..46; §167z records the 23 refutations.
cookbook_index.py: 508 sections.
I banked the crack agent's story that a wrong-TU citation CAUSED
func_8017F2D4's seven gate refusals, and relayed it to Drew, without checking
it. corpus.stubs() derives each stub's TU from the actual INCLUDE_ASM site and
gate_stage splices via corpus — the harness was always editing the right file.
Only the PROSE was wrong.
Measured: func_8017F2D4 is still a stub, still classifies DIFF, and is a
has_mid_jr function referencing jtbl_801CC504 — so it carries a jump table the
standalone gate cannot see. The real residual is CAUSE NOT DETERMINED.
The ORACLE stands on its own evidence (the asm subdir's third component IS the
TU stem, by construction from the split config). The causal story does not, and
is now marked as such. This entry was written to stop a tool printing an
unmeasured cause and its first draft printed one.
Wave 6 added 110 (24 cracks + 23/24 families propagated). Fleet 95.1% instr /
89.7% distinct / 96.51% fn-count. R22 clean-fleet run 9x this session, 213/213
every time. Bank rate across six waves: 67/79/69/68/73/60%.
Records §166a (the destination-TU oracle) and the four-instance pattern it
completes: a tool asserting a conclusion it never reached. A confident wrong
label costs more than a missing one.
gate_stage labelled every "standalone MATCH / whole-binary DIFF" with
"(declaration/TU plumbing)". The tool never checked for a declaration conflict —
that was a GUESS printed as a diagnosis, and func_8017F2D4 carried it through
SEVEN attempts across five waves while every agent hunted codegen. The body was
byte-correct from the first attempt; the notes had simply named the wrong
destination TU (a file holding only a caller + prototype), and splicing there is
a no-op that leaves the INCLUDE_ASM bytes in place.
- gate_stage now says only what is true (the two oracles disagree) and hands
over the check that resolves it, instead of naming a cause it did not measure.
- §166a banks the oracle: asm/<ov>/nonmatchings/<TU_stem>/<fn>.s => the
INCLUDE_ASM is in src/<ov>/<TU_stem>.c. The third path component IS the TU
stem, derived from the split config, and it beats any prose citation — a grep
for the function name also hits callers and prototypes in OTHER TUs and reads
exactly like a destination hit.
- Plus the two probe gotchas that cost wave-5/6 agents real time: the wrong
--aspsx-version fakes ~32 ori-vs-addiu mismatches, and a collateral-drift
check must filter to sized symbols (nm -S) or the zero-size .NON_MATCHING
aliases all report false drift.

Wave 5 added 152 (29 cracks + 28/29 families propagated) — the session's
largest. Fleet 95.0% instr / 89.6% distinct / 96.48% fn-count; stubs
13,345 -> 12,771. R22 clean-fleet run 8x this session, 213/213 every time.
P30's milestone is '>=95% instr fleet, or every remaining overlay stub on a
named ledger'. THE FIRST HALF IS NOW MET — T5 (phase close) is a live option.
Bank rate across five waves: 67% -> 79% -> 69% -> 68% -> 73%.
19 note-sets, 131 claims, one skeptic each, vetted against a cookbook that
already held §162/§163/§164 from this same campaign:
NEW 8 · SHARPENS 39 · COVERED 64 · UNSOUND 20
byte-probed 61 · single-instance 43 · asserted 27
COVERED+UNSOUND is 64%, up from §164's 57% — the duplicate rate RISES as the
knowledge base grows. That is the argument for harvesting after EVERY wave: a
wave launched before its predecessor's harvest lands re-derives laws already on
disk. This one was banked while wave-4 propagation was still committing.
THE PASS CORRECTED ITS OWN PREDECESSOR. §165-01 BOUNDS §163a, banked hours
earlier today. §163a says "block scope is a conflict SOLVENT" — byte-proven,
but on a DATA symbol. It does NOT reach an ARITY conflict: there the two decls
are COMPATIBLE (cc1 emits no `conflicting types` for scope to downgrade) and
the failure is call-vs-composite in convert_arguments (c-typeck.c:1623), which
a `()` declaration cannot defuse at ANY scope. The diagnostic word picks the
lever: `conflicting types` -> §163a's solvent; `too many arguments` -> cast the
call site (§17a-1/§161c) or replace the host prototype.
§165z records the 20 refuted claims. cookbook_index.py: 505 sections.
Wave 4 added 105 (27 cracks + 27/27 families propagated). Fleet 94.9% instr /
89.4% distinct / 96.44% fn-count. R22 clean-fleet run 7x this session, 213/213
every time.
Bank rate now measured four times: 67% -> 79% -> 69% -> 68%. Prior-notes
seeding 10/12 (was 7/9). func_8017C294 — the x16 family, largest item on the
board — is NEAR at 2 ins after three seeded attempts (18 -> 11 -> 2).
Also records the 4th comment-blindness defect and its blast radius (one draft
comment refused a binary's stub oracle, failed 5 later binaries, and left
drafts spliced in src/ so 17 re-gates read a poisoned tree as 0/17), and that
the wave harness now lives in tools/wave/ with its contracts written down.
The §163z catalogue was 34 crack-agent note-sets claiming 190 distinct laws.
One independent skeptic per function, each required to read the full notes,

57% of what the crack agents flagged as novel was already in the cookbook or
does not survive scrutiny. That ratio is the lesson: a crack agent is the right
instrument for FINDING a lever and the wrong one for judging its novelty — it
has just spent hours in one function and has not read the other 497 sections.
Never bank a wave's flags directly.
Banked as §164-01..82, each carrying its verdict, what it sharpens, and its
evidence grade (70 byte-probed, 12 single-instance). Several skeptics CORRECTED
the mechanism the crack agent proposed while confirming its effect — e.g. the
"fold distributes the constant out of an index" claim, where the skeptic traced
the real site to expand_expr's MULT_EXPR EXPAND_SUM case (expr.c:5359-5375)
after showing pointer_int_sum's distributive law cannot fire on that tree.
§164z records the 28 REFUTED claims with the reason, so no future wave spends
tokens rediscovering them.
cookbook_index.py: 501 sections.
The waves flagged ~40 candidate laws. Five were byte-probed, generalizable and
actionable enough to bank; they were deduped by hand against the file (no
skeptic-agent pass this time, so each says what it sharpens and why that
section is insufficient):
- §163a decl-conflict severity is SCOPE-DEPENDENT — hard error if either decl
is at file scope, warning only if BOTH are at block scope. §8d proves the
phenomenon on D_801812A4 but never states the rule or its LEVER half: block
scope is a deliberate conflict SOLVENT, so a struct-typed draft can be banked
into a scalar-typed TU by moving the typedef AND the extern into the block.
- §163b the switch-index parameter-WIDTH oracle: sll/sra straddling the minval
subtract is a 2-insn signature of a short parameter. Read the extension, not
just the bound.
- §163c case_values_threshold is 5 — an empty `case k:` glued to default can be
the only thing that emits a table at all; jtbl[k]==default label is the tell.
- §163d cse deletes a reg-reg copy by rewriting the PREVIOUS insn's SET_DEST
(cse.c:7440-7477). This is §162j's symptom in a DIFFERENT PASS and needs a
different lever; the residual it explains had been declared "unsteerable, 30
variants all >=17" and fell to source-shape edits alone, no pins.
- §163e the frame is a PSEUDO-NUMBER oracle (reload1.c:658 alter_reg in NUMBER
order); dead-local slot order is not declaration order, and a BLKmode local
is 8-aligned while a scalar s32 is not. Sharpens §162i, which gets the pad's
SIZE right and its PLACEMENT wrong.
§163z catalogues the ~35 unvetted claims by function so a future harvest can go
straight to them, explicitly marked "one agent's reconstruction until
re-measured" (R14).

Wave 3 added 84 (27 cracks + 21 propagated families). Fleet 94.8% instr /
89.2% distinct / 96.41% fn-count. R22 clean-fleet run 6x this session, 213/213
every time. 96 commits.
Bank rate measured three times: 67% -> 79% -> 69%. The dip is the cost curve
(wave 3's tier was 29 Opus-band / 14 jr vs wave 2's 8 / 5, median reach x6 ->
x3-4), not a regression.
Two levers proved out and belong in every future wave: the hardened harness
contract (0 drafts lost vs 21) and prior-notes seeding (7 of 9 previously
failed targets converted, incl. both long-standing NEARs and all three wave-2
gate misses). NEAR is a resumable state, not a write-off.
Session close state. Three parts: stage 0b (91, zero decompilation), wave 1
(26), wave 2 (116). Fleet 94.4% -> 94.7% instr, 88.3% -> 88.9% distinct,
13,345 -> 13,112 stubs. R22 clean-fleet run 5x, 213/213 every time.
The campaign now has a MEASURED rate, twice: 67% (wave 1, all-Opus) then 79%
(wave 2, 20 of 28 Sonnet) of cracks survive the whole-binary gate. The Sonnet
band beating the all-Opus wave is the session's most useful economic finding
and sets wave 3's routing.
Resume order changed on evidence, twice over:
- harden the wave harness FIRST (per-agent dirs, sha1-last verifier, and a
tools/recover_drafts.py built from the transcript-replay method that
recovered 21/21 today);
- then wave 3, sized on 79%, not on the reach-15 prior.
Error ledger grew to 6. The two that matter: I wrote off 21 verified cracks as
lost when the run transcripts held every one of them, and my first two
recovery passes both failed by reading a single tool record instead of
replaying the file's mutation history.
Stage 0b closed (91, zero decompilation) + Stage-1 wave 1 (8 cracks -> 26
instances). Fleet 94.6% instr / 88.8% distinct / 96.36% fn-count.
Resume order changed on measured evidence: FIX THE md_ MODULE LANE FIRST.
16 of the wave's 42 member slots were unreachable for tooling reasons, not
matching reasons — 12 on a carve that assumes raw data lives in
<binary>/data/*.data.s (modules do not), 4 on an uncarried extern
(`D_8011511A' undeclared). Both are named with verbatim errors; probe one of
each before pricing (R37). Precedent: 0b's three repairs banked 91 for ~0
agent tokens; the wave spent 3.36M for 26.
Also recorded: the frontier re-derivation (1,955 zero-crack families /
330,622 templatable ins), the tier-ordering correction (ins-per-crack is flat
across x5-x8, so rank by templatable weight, not by tier), and the §162
harvest with its two in-place cookbook corrections.
17 candidates from the 12 crack agents, each audited against the whole
cookbook by an independent agent before being written: NEW 3, SHARPENS 13,
COVERED 0 (one agent died mid-response — its entry, §162c, is written by the
orchestrator and labelled as the least-audited one).
The three genuinely new laws:
- §162e LICM: uniform loop-variable indexing is what makes a symbol address a
MOVABLE at all (a literal index leaves a constant, no base pseudo, no
hoist), and preheader order is body order.
- §162g cross-jump DIRECTION is a source-shape oracle: do_cross_jump always
keeps the LATER copy, so a BACKWARD jump into an earlier block can
never be cross-jumping — it is a source `goto`.
- §162n a conditionally-assigned alias pointer kills a spurious giv
(loop.c cant_derive).
Two in-place CORRECTIONS, because a reader who lands there first must not be
taught the superseded rule:
- §161a's "diagnostic tell (family-wide)" reads as a complete test on entry[0]
and actively teaches skipping the upper edge. Amended: check BOTH edges.
The maxval symptom is the OPPOSITE of the minval one — it shifts nothing and
costs two bytes, so it is functionally invisible.
- §25's triage rule prescribes pins for a symptom whose sibling mechanism
(local-alloc optimize_reg_copy_1) pins provably cannot reach, because
SMALL_REGISTER_CLASSES is never defined in config/mips/mips.h. Amended to
point at §162j.
The skeptic pass also caught two errors in MY submitted evidence: I had copied
§161a's minval symptom onto the maxval case, and I described func_8017F2D4 as
a verified MATCH when the whole-binary gate had refused it (it is still
INCLUDE_ASM). Both corrected in the entries.
cookbook_index.py: 495 sections, 14 symptom buckets.
Stage 0a's first defect, and the largest single zero-token bank of the session.
family_remap's kind test asked ONE question — is this address a function in the SIBLING'S OWN sig?
— and defaulted to `D_` on "no". But a body calls outside its image constantly: an overlay calls
resident helpers, an md_* module calls the overlay-range engine. Those addresses are absent from
the sibling's sig, so the test fell through and emitted a DATA NAME FOR A FUNCTION —
`D_800183E0`, `D_800D1EBC`, `D_80171A1C`. None exist anywhere in src/ or config/symbols.us.txt,
while `func_80171A1C` alone has 1,061 references. Measured: 611 member-rows across 45 symbols,
the largest named residue class. "Not in MY sig" means "not mine", not "is data".
Fix — three oracles, strongest first, never a blanket fallback:
1. the sibling's own sig (authoritative for its image; this is what preserves the Phase-29 T82
case where a slot is a function in the exemplar and DATA in the member — unioning every sig
would have re-broken the 251 members T82 fixed),
2. the always-linked images via extern_fn_addrs() — resident + main, 2,146 addresses whose ranges
cannot collide with an overlay's,
3. the exemplar reached it by `jal` — a call target is a function BY DEFINITION, which covers an
external address neither sig claims (0x80171A1C from an md_* module, 112 rows).
Only a non-call reloc no oracle claims still falls to `D_`.
Result: BANKED 205 member-matches, failures 670 -> 575, derived net = report = 205.
R22 clean-fleet 213 passed / 0 failed of 213.
Fleet 94.4% instr / 88.3% distinct / 96.27 -> 96.33% fn-count; stubs 13,563 -> 13,345.
THE RESIDUE HAS CROSSED OVER: DIFF is now the LARGEST class at 143 of 575 — real byte divergence
outranks plumbing for the first time this session (undefined-ref 611 -> ~8, PLUMBING-other
231 -> 81). The ~5:1 plumbing:DIFF ratio that justified "tooling beats volume" has inverted in this
queue, exactly as the frontier analysis predicted: the declaration-axis vein was one-time.
The new head class is `conflicting types for func_80175414` (27) — the same addresses this fix
started naming correctly, now surfacing the NEXT layer (the symbol resolves; its declared signature
disagrees). That is the conform axis, not the remap axis.
Note for anyone auditing this class: rtu_match MASKS HI16/LO16, so a wrong %hi/%lo symbol still
reports MATCH (the T82 comment records `MATCH (10 ins)` on a member the fleet gate refused). This
defect is invisible to the per-function tool by construction — only the whole-binary gate sees it.
The targeting oracle stamped its scope as "the N OVERLAYS only (no main, no resident)" while
load() has scanned the md_* modules and the resident since S44. Measured at this HEAD: 141 location
overlays + 70 md_* modules + the resident = 212 binaries. That is the §159 coverage law broken by
the file that documents coverage, on the repo's most load-bearing targeting instrument — and it is
how "main is structurally barren" survived two phases unexamined.
The COUNT beside it was already derived, with a comment saying "report the scope we ACTUALLY
scanned, never a hardcoded count". The PROSE describing what the count meant was hardcoded and
rotted. Both are derived now.
Caught while fixing it: my first cut read glob(".run/sig.main.jsonl") and stamped "main INCLUDED"
the moment that file existed — while load() still did not glob it. Same defect one layer down: a
stamp describing the filesystem instead of the run. Now derived from the loaded instances.
Also added a glossary line: "zero-crack" means n_matched == 0 (needs its FIRST crack) in this map,
and the OPPOSITE (a matched exemplar awaiting propagation) in roadmap §3 T3 — a ~30x mis-scope risk
for any session reading one against the other.
NOT DONE — main inclusion (0c) is still blocked on settling the attribution. Confirmed the
mechanism: main has 49 LINKED PsyQ subsegs, corpus.stubs('main') returns 2,002 INCLUDING them,
progress.py correctly excludes them and reports 1,034 game-code stubs. progress.linked_subsegs'
own docstring records this exact trap ("an importer then classifies ~1,300 already-byte-identical
LINKED library stubs as outstanding game-code work") — and my sig-main seeded from corpus.stubs,
so it inherited the LINKED rows, which is why G2's 207-family finding was inflated.
My partition probe is NOT trustworthy: 954 of 2,002 stubs returned no asm path from
corpus.asm_path, so 199 LINKED / 849 game / 954 unresolved does not reconcile with 1,034. Fix the
probe before trusting any main-scope number.
W1b — the 3 targets whose agents died on API rate limiting, retried with cookbook §160 in the
prompt: func_801EFBF4 (reach 12), func_801EFDC8 (12), func_8018CC40 (10, jr). 3/3 confirmed by an
independent verifier, all banked, R22 clean-fleet 213 passed / 0 failed of 213.
func_8018CC40 failed the first gate with `too many arguments to function func_80178970` — which its
own crack agent had PREDICTED in its report, naming the §17a-1 remedy. Dropped the draft's
empty-paren externs and cast 6 call sites instead; banked. Read the agent's integration notes
before diagnosing a gate failure — it has already seen the TU.
Cookbook §161a-c (index 469 sections):
§161a case 0: break; is LOAD-BEARING when a jump table is indexed from zero. The natural
case 1..5 makes gcc-2.7.2 pick minval=1, emit `addiu $v1,-1`, and shift every table index —
58 of 77 mismatched on a byte-perfect body. Tell: the table's FIRST entry points at the
function's own end address. Family-wide (10 members).
§161b aliasing a parameter into a local can force a SECOND callee-saved register (+8 frame,
+3 ins) even when uses are mutually exclusive. Suspect it before reaching for register pins.
§161c loose-prototype engine helpers: don't fight the TU's (void) decl, cast at the call site.
G2 — THE MAIN EXPERIMENT. family_hseq excludes main as "structurally barren — zero h_exact
overlap". True and irrelevant: an h_exact claim guarding an h_seq tool. There is not even a
sig-main target — main had never been signed for this pipeline. Signed it (2,002 fns, seeded from
splat boundaries via corpus.stubs rather than --bootstrap, which glues functions around jtbl
dispatch and would have corrupted the hashes under test).
Result: main is ~85% singleton work, not 100%.
internal h_seq families (>=2): 207 families / 748 fns / 11,537 ins (13.7%)
shapes shared with the fleet: 161 fns / 1,346 ins (1.6%)
genuine x1 remainder: ~71,034 ins (84.6%)
IMMEDIATELY ACTIONABLE: 44 classes / 151 main functions / 1,239 ins already have a matched exemplar
in the fleet — free propagation, invisible only because main is not in the map.
Long-term: 748 of main's 2,002 functions (37%) are templatable once one exemplar per family is
cracked, which refutes "2,002 independent cracks" as the planning assumption for the 79k-ins tail.
OPEN, deliberately not done unilaterally: adding a sig-main target and dropping main's exclusion
from family_hseq.load() changes a fleet-shared oracle every targeting tool reads. Needs Drew's call.
func_801EDC18 (md_SC05_023) is the largest multiplier remaining — 57 members. The wave agent
abandoned it at "closeness 6" with class SIZE-MISMATCH [redraft]. It was two lines from correct.
THE CODE (cookbook §160a): the target copies 8 bytes with lwl/lwr + swl/swr — gcc-2.7.2's
emit_block_move for a type with ALIGNMENT 1. The draft used a u32 copy (aligned lw/sw), which is
wrong by construction. `typedef struct { char c[8]; } Blk8; buffer = D_801ED98C;` reproduces it.
Six spellings were tried in parallel; two independent agents converged on the same one.
THE INSTRUMENT (§160b) — this is the part worth more than the function. The target .s bundles a
leading `.section .rodata` block (D_801ED98C as two .word) ahead of .text. Those lines carry the
same `/* off vaddr HEX */` shape as instructions, so masked_diff.insns_from_s counted them as TARGET
instructions, while insns_from_object (objdump -j .text) can never emit them. A byte-perfect draft
therefore read `mine=26, target=28, 26 mismatched` — every position shifted by a constant +2 — and
got classified as needing a redraft. 116 of 12,583 .s files in the corpus have this shape, one at
-29 instructions. Every one of them would report a false wall to any agent that tried it.
Fixed: insns_from_s tracks .section and counts only .text. Full-corpus control: 12,467 unchanged,
116 corrected, 0 regressions. Same artifact class as §129a (post-carve jtbl inflation).
THE OWNERSHIP LAW (§160c) — my own error, corrected by the gate. Four sites declare
`extern short D_801ED98C;` and nothing in src/ defines it, so I shipped an extern-only draft. The
gate refuted it: `undefined reference`. The .s block the draft REPLACED was the definition. The
variant emitting `const Blk8 D_801ED98C = {{...}}` banks clean. Never infer ownership from externs.
R22 clean-fleet: check-all 213 passed / 0 failed of 213.
ALSO BANKED — the wave's idiom harvest, which had been sitting unwritten in workflow transcripts
(R16/R30 debt): §160d the ASYMMETRIC INDEX RELOAD (a just-stored narrow field read twice emits
reuse-then-reload; the C is deliberately asymmetric), §160e a stack-layout scheduling rule now
byte-proven on a SECOND independent function (promoting it from coincidence to rule), §160f the
address-only global store via array decl, §160g sibling-search keyed on the CALLEE SET as step 0 of
every wave prompt (one grep turned a 126-instruction crack into a copy-edit).
Cookbook index regenerated: 468 sections.
The 10 exemplars from W1 flipped modal -> matched in the regenerated map, so family_sweep could
template them. 9 non-jr families swept: BANKED 140 member-matches / 32 failed across 50 overlays.
Derived net = report = 140 (no untracked carve files this time, so the two counts agree).
R22 clean-fleet: check-all 213 passed / 0 failed of 213.
Fleet 94.3 -> 94.4% instr / 88.2 -> 88.3% distinct / 96.22 -> 96.27% fn-count; stubs 13,713 -> 13,563.
WAVE ONE, FULLY ACCOUNTED: 10 agent cracks + 140 templated members = 150 functions for 1.36M
tokens (~9k tokens/function). Still owed from this wave: 73 member-slots in 2 NEAR families,
34 in 3 rate-limited targets, 9 in the jr family (routes to jtbl_family_bank, §53).
TWO MEASUREMENTS THAT CORRECT MY OWN FORECASTS (R14):
1. Conversion was 81%, not the 58% I projected from this morning's propagation run. Today's
plumbing fixes (alias-drop, cpp-derived TU type map, group-level draft-vs-draft aliasing) are
paying off in a population they were not tuned for.
2. The effective multiplier was 15x, not the 2-3.5x I predicted. That estimate used the MEAN
family size across the whole zero-crack pool (3.55); this wave deliberately targeted the TOP of
the reach distribution, where families run 10-28 members. Ordering waves by reach is what
produced the difference — the mean was the wrong statistic for a wave that selects on the tail.
The regen step is load-bearing and now byte-proven twice: a fresh crack reads as `modal` until sigs
+ family_hseq are rebuilt, and family_sweep templates only from `matched`. Skipping it sweeps a
stale map and the multiplier evaporates (the Phase-26 finding, whose surviving qualifier is that
remap works BEHIND a fresh crack).
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.
Regenerated after the S47-B/C banks (family_hseq.py + report): docs/family-hseq.md,
docs/progress.fleet.md, docs/backlog.md. Numbers only — no analysis change.
Frontier at this HEAD (overlays only): 7,085 families / 14,508 instances / 752,073 ins.
with siblings (>=2): 2,429 fams / 9,852 members / 467,634 ins (62.2%)
- matched exemplar (propagate, ~0 tok): 460 fams / 2,861 members / 125,630 ins
- zero-crack (crack 1 -> templates to N): 1,969 fams / 6,991 members / 342,004 ins
singletons: 4,656 fams / 4,656 members / 284,439 ins (37.8%)
- matched exemplar: 143 / 6,603 ins - zero-crack (pays x1): 4,513 / 277,836 ins
Structural: the x138 era is over — 3 fleet-wide families remain and ALL 3 already have matched
exemplars, so no fleet-wide CRACK is left, only propagation. 82% of remaining code now sits in
the two worst cost profiles (x2-9 zero-crack 45.5%, singleton zero-crack 36.9%).
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.
- BANKED: 11 functions at 400-952 ins from the cascade (func_8017D898 952, func_8017CE58 733,
func_801902EC 673, func_8018C2D8 673, func_8018A8D4, func_8017C6F4, func_800CBB38,
func_800CF3A4, +3). check-all 213/213 from a clean tree. 6 near = jr/switch (§53 separate
banking step), 1 failed. The cascade agents wrote 6 new cookbook sections incl. §158.
⚠️ tools-health UNVERIFIED at commit (stale cookbook index fixed, confirming re-run
interrupted) — run it first next session. check-all is the byte oracle and it is green.
- WASTE PREVENTION (Drew: "prevent this from ever happening again, however you need to"):
* tools/validate_targets.py (NEW) — names 5 defect classes (NO-ASM / MID-BODY /
OUT-OF-RANGE / ALREADY-DONE / NO-BOUNDARY), exits non-zero.
* WIRED INTO wave_snapshot so it fails closed — every wave passes through there for its .s
files, so no path from target list to spawned agents bypasses validation. Negative-control:
a 3-target bad list is refused with the exact mid-body offset (+72 bytes of 100).
* The cascade `done()` predicate now short-circuits on SKIPPED as well as MATCH. It tested
only MATCH, so a non-existent target fell Sonnet -> Opus -> Fable and three agents each
proved the same phantom absent: ~29 invalid targets x 3 tiers = 87 of 119 agents, ~9.7M
tokens. A tier that cannot act must END the pipeline, not escalate emptiness.
* docs/accelerators.md A9, including that wave_snapshot's own R32 assertion REFUSED that list
(24 of 57 found) and was routed around — the one instrument warning that was right and ignored.
- B RE-SCOPED (S46-10) and deliberately NOT done: the extend blocker is INTRA-HEADER, not
target-side. engine_core.h declares memcpy FOUR incompatible ways across its DEFINE_ macros;
two in one TU collide. NOT a safe cleanup — the in-tree note at ov_MAIN_012.c:14333 records
that `extern memcpy` disables gcc's builtin and turns an inlined block-move into a CALL, so the
declaration CHANGES CODEGEN. Probe one macro in one binary and byte-gate before any sweep.
- C (dedup_extend over the 129) stays blocked on B. Full context for both in the checkpoint.
Drew: "make it more multi-threaded... I still see my cpu idle for far too long."
Measured, fixed, and regression-tested against the S46-3 bank as a KNOWN ANSWER.
- THE MEASUREMENT: 31s saturated (33 makes/48 cc1/load 27) then ~25s with ONE build alive
while 31 cores idled, repeating. Causes: ex.map starts in list order so the giants land
last, and apply/restore is single-threaded.
- gate_all -> gate_failures: return EVERY failure the sweep already computed (~138 rounds -> 1).
- Longest-first gate scheduling; results re-sorted into `changed` order so the verdict stays
bit-identical to the serial loop's.
- PER-OVERLAY INDEPENDENT SEARCH, IN PROCESSES. My first cut used threads and the box refuted
it: 0-4 builds alive at load 3, because the work is regex over 15k-line files and 138
"parallel" searches all queued on the GIL. Same logic in a ProcessPoolExecutor: 14-29 builds,
load 34.75, search phase ~100s. Safe because the shared header is written ONCE by the parent
and each overlay owns its own .c files + build/<bin>/. Seeded with one in-process search
first — a pool submitted at once gives every worker an empty suspect list and makes all 138
pay a full bisection. place_in_overlay extracted to module level so the worker and the
in-process apply cannot drift (R33); compiles_standalone's fixed t.c is per-call now.
- THE REGRESSION (the point, not the stopwatch): revert src/+config to pre-bank, re-run the
identical command -> 29 functions (same), 141 overlays byte-identical, 682s vs ~1440s, and
285 exclusions vs ~350 => +62 MORE member instances (249,161). The old prefix-based
necessity probe was OVER-EXCLUDING (charging 4 fns to 9 overlays that did not all need
them); the per-overlay shrink minimises per overlay. The faster path is also more correct —
a timing comparison would never have shown it. R22 213/213 + tools-health green.
- STILL SERIAL, now the actual wall-clock (neither is a build): ~3min setup before the first
gate (registered_addrs() yaml-parsing a 1949-group/249k-instance registry + 213 sig loads)
and ~2.5min of sequential reconcile_caller_extern after the search.
- Captured as defaults: docs/accelerators.md A8 + memory fleet-tool-parallelism-defaults.
cookbook index regenerated (my §155c append left it stale — the gate caught it, exit 1).
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.
