- grinder.py: persistent blacklist for permuter-won/gate-rejected (plumbing-bound) fns;
stops the tried.clear()-after-idle churn (was 0 banks in 8h on func_8014F3E8/func_8014FE60)
- sig_unify.py rewrite_def: adopt the canonical param list on arity mismatch (DEF-side
loose-typing wall) — unused extras sit in $a0-$a3, free at -O2; banked func_8016EDEC/EE40
- cookbook §22 (DEF-side recovery + grinder blacklist); CURRENT_PHASE option-C log
- compounds: sig_unify is in the gate pipeline -> every future wave + the grinder auto-recover
- residual class travels with the draft: drafter stamps // @class / // @stuck; gate_stage logs
the worker's gcc-quirk class to the backlog (not the coarse manifest class).
- wave_targets.py --class <C> / --list-classes: class-grouped re-attempt waves over the backlog's
classified near-misses (REGALLOC/SCHEDULE/REMAT/STRUCT/IV/LOOPGUARD/LOOSE/PLUMBING).
- orchestrator prep: auto-picks a class-focused wave when a class accrues >= threshold near-misses,
else a fresh pool harvest; clears the draft dir per wave.
- tools/workflows/distill.js: post-wave agent extracts NEW byte-verified gcc idioms -> cookbook §21
(R16, conservative); drafters now read the LIVE cookbook so distilled idioms feed forward.
- runbook: the full prep->worker->gate->distill cycle (the Phase-18 close-rate loop, automated).
- gate_stage on the 15 worker drafts saved before the reboot: banked 2 byte-matches,
propagated x134 (dedup 1508->1510); the gate process was killed pre-commit (empty log),
banks recovered from the working tree (dedup_propagate fail-closed per-overlay = verified).
Remaining 13 -> backlog near-misses.
- the %lo-folding indexed-global -O0 residual (§18, long "irreducible") is CRACKED: declare
the global as "extern Struct base[]" (sizeof == stride) and access "base[i].field" -> gcc
keeps sym a symbol_ref and folds %lo(sym+off) into the store, byte-matching. The failing
forms "*(T*)(&sym + i*stride)" materialize &sym as a value first, blocking the fold.
- func_8013B7AC byte-gated + banked (x1 — the -O0 cluster is overlay-local, R14 finding above);
the idiom is reusable fleet-wide for ANY indexed-global access (-O0 or -O2).
- cookbook §18 ("%lo-folding indexed global — CRACKED") + §20 placeholder closed.
- the other 9 -O0 stubs: idiom applies but need per-fn -O0 drafting (3 quick ones tried, failed
on -O0 codegen detail; 4 are large) -> backlog/autonomy fuel. clean rebuild d19c9580 (R22).
- byte-proven: 0 drafts declare an extern struct/union data conflict; the lone apparent
DATA-conflict (func_8016A8FC/D_800AE620) was a typedef-REDEFINITION (Blk20 inline vs
engine_types.h, same type) masking the def-sig loose-typing wall. Stripping the inline
typedef compiles but still byte-mismatches. data-cast = code for 0 cases -> not built.
- cookbook §20 DATA-conflict note corrected; fleet unchanged 58.82%.
- byte-proven: only 1/134 overlays shares ov_SC01_077's -O0 cluster bytes; the 6 matched
-O0 fns reference per-overlay data addresses (func_8013B568 -> D_80187270 in ov_SC01_077
but 0x80182B04 in ov_SC01_005), so they're overlay-LOCAL, not ×134-shareable. The
Phase-18/19 'reach-134' label conflated function-present with byte-identical (R14).
- the §18 split infra (rollout tool + Makefile %_o0.o pattern + PROVIDE .ld) was built and
byte-validated to compile/link a 2nd overlay; the whole-binary gate then exposed the
per-overlay-data wall -> reverted (the finding is the deliverable, P9).
- -O0 rollout = ×1 per-overlay-unique re-matching (~0.2-0.3%), NOT +0.6% free -> SKIP.
cookbook §18 corrected; fleet unchanged 58.82%, 136/136 byte-identical.
- tools/cast_call_sites.py: per draft, callee whose canonical TU sig != draft's
intended sig -> decl->canonical (kills in-TU conflicting types, keeps symbol in
scope) + call-site cast ((ret(*)(args))func_X)(args) (codegen-neutral: gcc folds
the cast of a known symbol -> direct jal). Pure --in/--out; whole-binary gate is
the arbiter (G3/P9). Pipeline: canon_resident_calls -> cast_call_sites ->
sig_unify -> harvest_verify --chunk 1
- recovered 6 of T6 batch-1's 33 gate-fails byte-identical (func_80153C44/8015CF58/
801711FC/80161BE0/801683D8/8015F948); 5 propagated x134 + 1 local; check-all 136/136
- R14 CORRECTION of cookbook §20's '~33' projection (byte-proven): the batch is NOT
mostly callee-conflicts — ~6 callee (cast-recovered), ~18 DEF-side loose-typing wall
(def's matchable sig conflicts with the unchangeable caller-canonical; caller-side
fix BLOCKED because INCLUDE_ASM declares no symbol -> a shared macro's internal
extern is load-bearing in the 133 stub overlays), + a small DATA tail. The def-side
needs re-drafting under the caller-canonical sig (future wave), not a text transform
- cookbook §20 RESOLUTION + SETUP tool inventory (R16/R21/R30); CURRENT_PHASE log (R28)
- fleet 58.63% -> 58.82%, dedup 1501 -> 1508, 0 NON_MATCHING (G4)
- build_engine_types.py --strip: lifted 48 named types -> src/shared/engine_types.h
(byte-neutral, ov_SC01_077 d19c9580); unblocked +4 struct-using matches -> propagated ×134
(incl. func_80147514, a T2 match freed by the lift)
- check-all 136/136 BYTE-IDENTICAL (R22); fleet 57.93% -> 58.00%; phase total 56.64% -> 58.00%
- KEY FINDING: propagation (not matching) now caps the fleet-% yield — ~16 banked matches stay
ov_SC01_077-local because their bodies use typedef'd/anonymous/sibling local types that the
named-struct-only build_engine_types can't lift (dedup_propagate compiles_standalone rejects).
Phase-20 lever: extend the type-lift to typedefs -> recovers those ×134 for ~0 agent tokens
- R14 finding: the 3 Phase-18 "implicit-int / propagate-first" near-misses are NOT
implicit-int (reproduced each through the byte-gate). Real classes:
(a) resident-callee LINK-miss: draft calls func_<ADDR> but the addr has a curated
name (0x8004CFEC = ratan2) -> "undefined reference to func_8004CFEC". NEW
tools/canon_resident_calls.py rewrites func_<ADDR> -> curated name (pure draft
text, body bytes unchanged) -> run FIRST in the recovery pipeline.
(b) shared-caller ARITY conflict: an engine_core.h caller macro declares the callee
file-scope `extern void func_X(void)` then calls func_X(); the real def takes an
arg -> "conflicting types". FIX = caller extern -> no-proto `extern void func_X();`
(byte-neutral for the caller; compatible with promotion-safe params int/long/ptr).
- 3 matches banked in ov_SC01_077: func_8017209C (ratan2 rewrite), func_80147514 (s32),
func_80168F40 (void*); 2 no-proto lines in src/shared/engine_core.h
- recovery pipeline: draft -> canon_resident_calls -> sig_unify -> harvest_verify --chunk 1
- make check-all 136/136 BYTE-IDENTICAL (full extract, R22); dedup 1450 validated/0 failed;
0 NON_MATCHING in any default build (G4); fleet 56.64% (the 3 are ov_SC01_077-local,
x134 propagation rides T3/Phase-20)
- cookbook §17a-3 corrected (R14/R16); SETUP tool inventory (R21); CURRENT_PHASE T2 done
- §17 rewritten: the call-crossing register-ORDER class is MATCHABLE with register
__asm__ pins + a scheduling barrier (byte-proven func_8012B8E4), not unsteerable.
The wall was a missing lever (the pins), not an impossibility. Recipe documented as
a TOOLKIT: triage with match_one -> reconstruct / array-decay / PINS / barrier.
- §16 cross-refs + hand-matching §8e corrected to match. The ONLY genuine stub-and-skip
left is the narrow-param loose-typing conflict (func_80146A6C).
- self-correction (P9/R14): I concluded 'unsteerable' before trying the pins; Drew's
hand-match-everything directive exposed the gap. Recorded honestly.
The 'unsteerable' regalloc-order class is NOT unsteerable. Drew's directive (hand-match
everything) exposed the lever I'd skipped: explicit register pinning.
- func_8012B8E4 (the flagship circular reach-134 'unsteerable' fn): 21 -> MATCH via
* register pins: register s32 d __asm__("$16"); register s32 s1ang __asm__("$17")
-> FORCES the $s0/$s1 global allocation gcc otherwise density-orders the other way
* branch-polarity invert (§3-T4): 24->21
* explicit clamp temps (t=u6+0x1000; iVar4=u5-t): fixes the reassociation, 7->3
* scheduling barrier __asm__ __volatile__("" : : "r"(u5)): anchors the last sll, 3->MATCH
- byte-gated (harvest_verify, G3/P9) + propagated x134 (per-overlay gate); 134 byte-identical
- recipe = §10-family hand technique (pins + barriers); labor-intensive (per-fn register map
from the asm) but it WORKS -> the circular tail IS hand-matchable, not asm-only
- supersedes the T1-T5 'unsteerable' verdict; cookbook §17 + PhaseEnd to be revised accordingly
