- housekeeping: deleted stale root gccdump.lreg (gcc default -da RTL dump, dumpbase
"gccdump"; a one-off RTL-inspection run at root CWD, NOT a committed tool). Practice:
RTL dumps go to a .run/ CWD or -dumpbase .run/gccdump (R12)
- make sig-overlays (134 sigs); worklist.py --refresh -> build_fuel_manifest + backlog
render: docs/worklist.md + docs/backlog.md regenerated (stale Jun-26 ranking killed;
the banked whale func_80144B9C dropped from backlog, P9)
- fix tools/sig_image.py docstring: h_norm is the live norm_stream normalizer, not a
"T5 placeholder" (R21/R30)
- CURRENT_PHASE.md: Phase-25 plan-of-record + T0 frontier survey (R14): h_norm 2,764
multi-member families / 11.1 MB; 46% of large solo monsters (3,989/8,670) are family
members; reach-134 h_exact warm-up = 130 classes / 4.11 MB
find_site + dedup_propagate --recover + build_engine_types fixes, then re-bank
the 13 recover_integration leaf-MATCHes and propagate each across all 134 overlays.
- find_site: match INDENTED inline defs (was column-0 only, silently dropping every
recover_integration-banked def from propagation — T6 blocker 1). Unit-tested:
indented defs match; indented call-exprs (if/assign/bare/return) correctly rejected.
- dedup_propagate --recover: on a straggler byte-gate failure, FIRST no-proto that
overlay's conflicting caller extern + re-gate (Part B, byte-neutral, same lever as
fix_arity_callers --any-proto); else EXCLUDE only that overlay (Part A, ×N-1) rather
than the historical all-or-nothing drop. Wired into gate_stage.
- build_engine_types: comment-aware find_defs/find_typedefs (blank_comments). The
generated header's own "...typedef lift" comment was captured as a bogus `typedef
vec`, self-colliding and blocking every --strip. NOTE: full --strip still conflicts
with the _a/_o0 split files, so split-file overlays need a TARGETED lift.
- banked + propagated 13 fns ×134: func_8014F74C 801542A4 8015BE94 8015F380 80160F00
801653B8 80166244 8016E778 801732C4 8017331C 80173374 80174554 801745AC.
func_8014F74C needed PosT/MoveT lifted to engine_types.h (targeted, byte-neutral).
- dedup 1784→1797 groups (0 failed). CLEAN fleet check-all 136/136 BYTE-IDENTICAL (R22:
make clean && extract-all && check-all). Fleet REAL 224073, byte-identical 65.40%.
R14: the confounding stale-asm/ tree (13 missing .s) that masked the first --recover
test is fixed by re-extract; the 3 pre-existing --auto-from stragglers (0x80174650/
8012A018/80165CA0) are pin/asm + uncaptured-local-macro (SHB) bodies, correctly dropped.
Both concerns byte-verified from a fully-clean tree (ov_SC01_077 d19c9580, ov_SC07_009 2a6499b6
+ 133 overlays). Fleet is 135/136 — the 1 remaining failure is `main`, a SEPARATE pre-existing
Phase-21 breakage (62 dangling INCLUDE_ASM refs, tracked in CURRENT_PHASE, fix in progress),
NOT introduced by this commit.
[FIX (partial) — pre-existing Phase-21 latent breakage, found during T5b's fleet verify]
- A genuinely-clean `make check-all` failed 135/136 (overlays: `undefined reference to func_80058B40`;
main: dozens of `can't open asm/nonmatchings/800c3/func_*.s`). This commit fixes the OVERLAY side.
- Root cause: Phase-21 xdedup renamed func_80058B40 -> GetTPage in symbols.us.txt (one of the
+62 PsyQ names) but did NOT update the two shared engine_core.h macros that CALL it
(DEFINE_func_80139680, DEFINE_func_8012E28C — in all 134 overlays + ov_SC01_077_a). Since
Phase 21 a clean rebuild couldn't link; incremental builds reused stale .o's and masked it
(the R22 failure mode) — every "check-all 136/136" Phase 21->23 was incrementally-stale.
- Scope = exactly 1 symbol (static scan of all func_/D_ refs in the shared headers vs symbols).
- Fix: rename the 4 occurrences -> GetTPage (byte-neutral, same addr 0x80058b40 -> identical jal;
G6 curated-name). ov_SC07_009 link-fail -> byte-identical 2a6499b6.
- Lesson: a symbols.us.txt rename must be propagated to shared-macro bodies AND verified by a
genuinely clean (make clean + full re-extract) check-all, never incremental.
[FEAT — T5b: the S11 class crack, Fable5 spike]
- The S11 LUID(x)alloc "intrinsic" verdict was MAP-INCOMPLETENESS. func_8014E048 (143 ins,
reach-134; "not source-steerable" since the map wave; 28-off even after T5's directed permuter)
-> MATCH (143/143) -> whole-binary BANKED (ov_SC01_077 d19c9580). Derived by reading gcc-2.7.2
source + RTL dumps (12 experiments .run/gccmap/exp/e1a..e1k.c).
- NEW LEVERS (byte-proven): S12 reused-s32-temp fence (u16 temps DON'T work — combine folds the
unpromoted-HI zext temps away); S13 head-skip escape (body-local param copies conflict-steer the
scratch contest; volatile-asm dead-read wedge fence; multi-input dead-read K2 rebalance);
cse-opaque asm-copy; RC-4b pinned store-temp; RC-10 preference-cascade mechanics.
- Integration reconciles (both T6 classes): engine_core.h caller decl s16*->u16* (codegen-neutral)
+ canonical data decls w/ *(u16*) casts (D_801152A8 u8[] / D_801152AC s16). x134 lift blocked by
dedup_propagate self-containment (pins/asm) -> T6 target (joins func_80132784).
- Distilled (R30/R16): sched.md §6 (S12/S13) + regalloc.md §F (RC-10 + RC-6/S11 downgrade) +
cookbook §31 triage update; backlog re-logged (capped); memory updated.
The grinder/backlog pipeline was ov_SC01_077-hardcoded 5 layers deep (same class as the
T7 lora_grind bug). Fixed all so the permuter grinder can process a non-077 near-miss:
1. gate_stage.append_record stores the source "binary"
2. backlog.FIELDS keeps it (else append_record dropped it)
3. backlog.load_best/_open_stubs is fleet-aware: a fn matched in ov_SC01_077 but
propagation-stuck stays OPEN in its overlay, so it surfaces via that record instead
of being dropped as "matched" (the grinder must SEE it to grind it)
4. p16_permute.setup takes the target binary's asm-subdir (was hardcoded 077)
5. grinder resolves per-binary asm + gates grouped by binary + allows unknown nins
Backward-compatible: legacy records (no binary) default ov_SC01_077.
Validated end-to-end: the 3 fresh reach-134 close=1 ov_SC01_000 fns now surface, resolve
to ov_SC01_000's asm, and gate via ov_SC01_000.
TWO byte-evidenced findings (redirect the fuel strategy):
- the reach>=2 close=1 fuel is MODEL semantic-misses, not permuter fuel: func_8012E27C's
target is "return 1" but the 7B drafted an empty "void f(void){}" (corpus overfit
empty-leaf); func_8012BF4C/AD64 are trivial sw/sh setters drafted empty. A corrected
draft banks them (+3 byte-identical via the fixed gate, @commit:0326); the permuter cannot
add a missing return/store. Lever = corpus-v3 leaf variety, not the permuter.
- x reach is propagation-capped: the 3 are inline-matched in ov_SC01_077_a.c (the stuck-
local cap) -> dedup_propagate "nothing to propagate" -> banked x1. Lever = dedup-collapse.
check-all 136/136 throughout. docs/gen2-mips-matching-model.md + CURRENT_PHASE updated.
The 500-fn calibration banked 0/222 across the binary rotation. Root-caused (R14, by
reading the code + the run's own backlog — resolving a flat contradiction between two
scout agents) to TWO independent bugs in lora_grind's use of gate_stage.run_gate, NOT
model quality:
- Bug A: good_sha() passed the sha1sum line "<sha> <name>" vs harvest_verify's bare
sha1() -> 0 banks for EVERY binary incl. 077 (so the "0/12" was a bug artifact, not
an exhausted tail)
- Bug B: the gate call left src/asm/out at the hardcoded ov_SC01_077 defaults -> non-077
drafts dropped at the 077 stub-filter, silently (and the asm mis-resolution contaminated
the backlog near-miss classification)
Fix (tools/gate_stage.py): run_gate resolves src/asm/out/good_sha from `binary` when unset
(binary-agnostic, no silent ov_SC01_077 default an overlay inherits; good_sha bare-hash
normalized) + a loud negative-control guard (0-overlap binary/src mismatch warns, so a 0
can never again masquerade as 'nothing matched'). tools/lora_grind.good_sha fixed at source.
Byte-neutral: make check-all 136/136.
Proof: ov_SC01_000 spot-run banked 7/15 (47%) byte-identical (@commit:0322); reach-2
func_8017CE24 propagated x2. ROI finding: 6/7 banks are reach-1 (overlay-unique) -> broad
rotation is high bank-RATE / low fleet-% ROI; the fleet lever is reach>=2 targeting (T9) +
corpus-v3 (T8). Backlog now correctly classified (4x close=1 = grinder fuel).
- docs/gen2-mips-matching-model.md: T7 RESULT section
- phase-ends/CURRENT_PHASE.md: T7 done; next = T8 corpus-v3 / T9 reach>=2 selection
The fine-tuned 7B (bfm-match-7b-v2) drafted real OPEN ov_SC01_077 stubs; whole-binary gate banked 4
(func_80160B34 func_8015CC74 func_8016084C func_801705C0). Sample: 9/22 match_one proxy -> 4/22
whole-binary banked (18%; the proxy->gate gap is the TU-plumbing wall). Model is format-robust (raw .s
== normalized). api_draft: NORMALIZE_ASM bridge (unused — model handles raw .s) + ghidra_c-empty fix.
- from-scratch giant func_801372B0 (207): structurally cracked at xHigh (206/207 ins,
logic 100%%) but byte-blocked by the gcc list-scheduler/regalloc last-mile (§27/§17);
banked the structural draft to backlog as a future permuter head-start
- xHigh finding (Drew's test): giants reach structural match fast — the wall is gcc
determinism, not reasoning depth; xHigh sufficient for this work
- session total: 16 functions ×134 (2 giants type-lift + 14 close=0), fleet 63.22%->63.66%
- docs/{worklist,backlog,progress.fleet}.md regenerated after the func_8015126C x134 bank
- CURRENT_PHASE.md: RESUME HERE block (T2 giant queue + levers + op gotchas) for a fresh session
- grinder stopped (STOP sentinel set); tree clean except R23 db churn
The 2nd straggler class (cont.4 wave-2): cross-overlay loose-typing COMPILE errors (not just
the -O0 byte-mismatch class). The -O0 exclusion alone was insufficient. Refactor the propagation
into a drop-straggler retry loop: extract apply_plan(subplan, restrict=); on a byte-gate failure,
isolate the culprit(s) for the failing overlay (per-fn trial), drop them (kept x1), retry the
survivors. Handles BOTH straggler classes failing ANY overlay; plan strictly shrinks (terminates);
byte-gate stays sole arbiter (a dropped fn never banks where it isn't byte-identical).
Validated end-to-end: wave-2 --auto-from auto-dropped 2 loose-typing stragglers + propagated 3
clean x134 (commit:0271); fleet 62.70 -> 62.82%. Future _a waves now auto-realize x134, no manual probe.
- worker_wave.js: derive match_one self-check --asm-subdir per-target from t.asm
(was hardcoded main subdir -> every _a agent self-check crashed on missing .s ->
blind drafting). Enabled the 16/24 close rate on the _a measurement wave.
- CURRENT_PHASE cont.4: the _a vein is x134 (10/11 propagate byte-identical), not the
cont.3/§24 x1 wall. The gate's propagated:0 was 2 bugs: dedup_propagate all-or-nothing
batch-revert poisoned by 1 stale -O0 overlay-local straggler (func_8013C360), and
gate_stage sh() swallows dedup_propagate's non-zero exit. Realized +0.39% (commit:0267).
- 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
- 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.
