Drew T e44bc787eb feat(phase-29): func_80135EB0 banked (289 ins) — 418-site pointer-shape decl axis, R22 140/140
The largest target on the T14 census: 138 members x 289 ins = 39,882 templated instructions at stake.
conform_decls --check showed 418 sites in 3 forms, pointer-type-only with NO narrowing warning and no
return-type change — the func_80179B74 shape that banked 137/137. Applied (418 sites / 414 files),
gated (jtbl carve succeeded first try), R22 clean-fleet 140 passed / 0 failed of 140.

Committed BEFORE the family bank because jtbl_family_bank refuses to run on a dirty tree — its
per-sibling revert restores from HEAD, so an uncommitted axis would be destroyed. The tool enforcing
H4 in code, correctly.

Also recorded: family_sweep REFUSED this family rather than returning 0/137 — func_80135EB0 is
has_mid_jr, and §53's carve law says a carve-less sweep there yields "a 0% that is a TOOL artifact,
not a wall". That refusal is the good version of today's pattern: every false wall untangled this
session (func_8016B6BC 0/137, the 4 fabricated CC1-FAILs, Phase-28's B2 0/8) came from a tool that
ANSWERED instead of refusing.

Drew T acc8d762a0 feat(phase-29): func_80179B74 family swept 137/137 (R22 140/140)
134/134 BANKED on the remainder after 3/3 on the probe — the FOURTH full-family sweep this session,
all four unblocked by the --like role guard, three of them 100%.

Drew T 2985f306d9 feat(phase-29): func_80179B74 banked — conform_decls cleared it as pointer-type-only (R22 140/140)
1,600 decl sites across 523 files, in THREE different forms (s16 *a0 / short * / short *p),
conformed to the byte-true 'void func_80179B74(u16 *p)'. conform_decls ALLOWED this one: the arity
is unchanged, so no 0-arg call site can break, and the return is unchanged, so §85's precondition
does not apply. Gated BYTE-IDENTICAL; R22 clean-fleet 140/140.

The tool has now refused one axis (func_8015B950, correctly — it would have broken 138 binaries)
and cleared another (this one, correctly). Both verdicts held under R22.

Drew T 6b9e2b7f33 feat(phase-29): func_8016AE5C family swept 136/137 (R22 140/140)
133/134 BANKED on the remainder after 3/3 on the probe. ONE sibling refused (ov_SC03_108,
gate-fail) and is left as a stub rather than forced — a 136/137 recorded honestly beats a 137/137
that needed a shortcut. Third full-family sweep this session, all three unblocked by the --like
role guard.

Drew T d4c4a4d563 feat(phase-29): func_8015B950 family swept 137/137 (R22 140/140)
134/134 BANKED on the remainder after 3/3 on the probe — the second clean full-family sweep this
session, both unblocked by the --like role guard. func_8015B950 is stubbed in NO overlay.
R22 clean-fleet: extract-all 139/139, check-all 140 passed / 0 failed.

At 271 ins x 137 members this is the session's largest single family by instruction weight.

Drew T 8b52bdb30b feat(phase-29): func_8015B950 family probe 3/3 banked (each whole-binary gated) 2026-07-27 11:57:26 -06:00
Drew T f459f53083 feat(phase-29): func_8015B950 banked — ONE cast unlocked the 925-site axis that broke 138 binaries
The same axis that broke 138 of 140 binaries an hour ago now lands clean, because conform_decls'
NEW arity guard located the actual obstruction instead of leaving me to absorb it by hand.

THE OBSTRUCTION WAS ONE LINE. Conforming `extern s32 func_8015B950(void)` -> `(s32 arg0)` turns
every 0-arg CALL SITE into `too few arguments`. My hand attempt assumed those were spread across the
926 TUs and would need 926 casts (the func_8012AAAC precedent, where it really was 137 separate
sites). They are not: there is exactly ONE call, in `src/shared/engine_core.h`'s
`DEFINE_func_8015BEE4()` macro body — expanded into all 926 TUs by the preprocessor.

func_8015BEE4 is a THUNK: `return func_8015B950();` with $a0 passing straight through from its own
caller. So the 0-arg call shape is byte-CORRECT and must be preserved, not fixed —
`return ((s32 (*)(void))func_8015B950)();` keeps it exactly (§17a-1; gcc folds the cast of a known
symbol to a direct jal, and the s32 return is unchanged so the thunk's value still flows).

Sequence: 1 cast -> conform_decls --apply (925 sites, R32 completion assertion: 0 remaining) ->
gate BANKED byte-identical -> R22 clean-fleet extract-all 139/139, check-all 140 passed / 0 failed.
The draft's 2 callee-decl conflicts (func_801725A4, func_80147078) dissolved with the axis.

Worth 37,398 templatable ins; the ×137 family sweep is next.

Drew T 7c1640888f feat(phase-29): func_8016AE5C banked + tools/conform_decls.py; a 138-binary break R22 caught
BANKED: func_8016AE5C (85 ins ×138). R22 clean-fleet 140/140.

⚠️ I BROKE 138 OF 140 BINARIES AND R22 CAUGHT IT — the per-binary gate could not.
Conforming func_8015B950's decl from `(void)` to its byte-true `(s32 arg0)` across 926 sites gated
BYTE-IDENTICAL on ov_SC01_077 and broke 138 other binaries with Error 33. §63/§85 exactly: a T2
write set is provable only by R22, and the binary the gate authorises is not the binary that breaks.
MECHANISM: conforming a decl to a signature that TAKES parameters makes every existing 0-ARG CALL
SITE a hard `too few arguments` error once a prototype is in scope. Not a declaration-only change.

PROCESS NOTE (mine): a first R22 reported 138 failures, an individual rebuild of a "failing" binary
said BYTE-IDENTICAL, and I nearly filed it as a flake. The second clean R22 reproduced it exactly —
the individual build passed only by reusing objects the clean run rebuilds. An incremental pass does
not refute a clean-tree failure; that is R22's whole premise, pointed at me. Reverted to a known-good
baseline (a stray jr_isolate region file was also in the tree) and redid the one good bank cleanly.

NEW tools/conform_decls.py — because applying this axis by hand three times in one session is how a
half-axis happens. Derives the byte-true signature from the DRAFT's definition (§58b), rewrites EVERY
site, asserts completion (R32). Encodes both preconditions: the §85 return axis (refuse if any caller
consumes the return) and a NEW arity precondition (refuse if 0-arg call sites exist, naming the cost).

The guard immediately gave a better diagnosis than my hand-fix had: func_8015B950's 0-arg call is in
ONE place — src/shared/engine_core.h, a DEFINE macro body — expanded into all 926 TUs. That fix is a
SINGLE cast, not 926 edits. Named as the next step rather than run on tired context.

Also lands cookbook §91 (the --like role trap) from the previous step.

Drew T ab3ac83a41 feat(phase-29): func_8012AAAC family swept 137/137 — the --like guard unblocked the whole class
- 134/134 BANKED on the remainder (after 3/3 on the probe) => the family is 137/137, ZERO failures.
  func_8012AAAC is now stubbed in NO overlay. R22 clean-fleet: extract-all 139/139, check-all
  140 passed / 0 failed.
- FLEET 81.9 -> 82.0% instr · 89.60 -> 89.64% fn-count · distinct-code 69.3 -> 69.5%.
- THE METRIC POINT, reproduced twice in one session and in BOTH directions: this jtbl family is
  byte-VARIANT (each overlay's table holds its own addresses), so every member is a genuinely new
  unique function and distinct-code MOVED. The h_seq PURE families swept earlier added 274 members
  and moved distinct-code by +0.0, because those members were already counted via their shared
  exemplar. SESSION-20's routing rule, now byte-demonstrated: target byte-VARIANT families to move
  RE-completeness; high-reach h_exact families move only the display number.
- cookbook §91 — "a structure-TRANSFER is only valid where the structure corresponds": the --like
  role trap, plus the three-hypothesis trail (two wrong, and instructive: the sibling call-site casts
  were a real defect that fixed nothing, and my own carve-alone test was a false lead that departed
  from the tool's real sequence). The law: any "same family => same structure" transfer must state
  which structural fact it assumes and CHECK it on both sides — and a tool that drops an error class
  it cannot act on should still SURFACE it, because a bare `gate-fail` repeated 137 times cost far
  more than printing one line would have.

Drew T a5e5ea45ef fix(phase-29): jtbl_carve — guard the --like role-transfer; the ×137 sweep goes 0/3 -> 3/3
ROOT CAUSE of the 0/3 (found by reading the tool's ACTUAL invocation, not by guessing):
jtbl_family_bank calls `jtbl_carve <sibling> --func <fn> --like <exemplar_ov>`, and the role-transfer
keys on the SUBSEG ROLE (`ov_SC01_077_a` -> `_a`). Its premise — "same family => same span
structure" — silently breaks when the exemplar and the sibling host the function in subsegs with
DIFFERENT roles, which happens whenever the exemplar has a split the sibling does not.

MEASURED: func_8012AAAC lives in `ov_SC01_077_a` (role `_a`) in the exemplar but in the MAIN subseg
(role ``) in every sibling. The transfer therefore looked up `ov_SC01_077` — an unrelated SEVEN-table
span belonging to entirely different functions — and stamped those starts onto a sibling span holding
one table. jtbl_rodata_pads then refused with `consumed 1 rodata .align(s) but 2 pad spec(s) given —
table-count drift`, and jtbl_family_bank deliberately does NOT treat that error as isolate-fixable,
so all 137 siblings returned a bare `gate-fail` with the cause discarded.

THE FIX: transfer only when the exemplar's subseg for THIS FUNCTION has the sibling's role; otherwise
derive the span from the sibling's own carve (which was already computing it correctly). Fail-open is
not acceptable here — a wrong table set corrupts the image, so the guard defaults to local derivation.

MEASURED RESULT: the 3-member probe goes 0/3 -> 3/3 BANKED. R22 clean-fleet: extract-all 139/139,
check-all 140 passed / 0 failed.

Two earlier hypotheses were tested and are recorded honestly in CURRENT_PHASE.md: the sibling
call-site casts (real conflict, fixed, byte-neutral — but NOT the blocker) and my own carve-alone
test (which fails by construction for this shape, because a stub object does not emit the table its
2-entry spec describes — the tool splices the body BEFORE building, so its path is the valid one).

Drew T 2cc49d0310 feat(phase-29): SESSION-21 — func_8012AAAC banked via the §81 carve chain (R22 140/140)
The first jtbl-routed bank of the session, and it validates the whole chain end-to-end:
 1. jtbl_carve SPLIT-TABLE repair (this session): jtbl_801D7FB0 28 -> 50 words (112 -> 200 B),
    authorized by func_8012AAAC's own `sltiu 0x32`.
 2. NEW FIX — SINGLE-TABLE PREDECESSOR: adding a second table to a subseg whose existing carve was
    single-table lost the FIRST table's start entirely (new_offs has only the new one;
    overlay_jtbl_addrs cannot see the old one because its owner is banked and extract PRUNED the
    stub .s; and single-table carves persist no tables= to rebase). The span then failed its own
    validator with "first must equal the span start" — the invariant naming the missing entry.
    A single-table carve spans exactly its one table, so ITS SPAN START *IS* THAT TABLE'S START:
    inference, not persistence, so it also works for spans carved before tables= existed. This is
    the RECOVERABLE half of the documented func_8013F350 lesson (that one was a pre-§8e merged
    DOUBLE — two tables, no record, genuinely unrecoverable).
    Result: ov_SC01_077_a JTBL_PADS := 0,0 tables=+0x0,+0x14. Carve alone byte-gated BYTE-IDENTICAL
    BEFORE the bank was attempted (§81 step 2).
 3. ARITY axis, all-or-nothing: 1,244 decl sites / 1,240 files `(void)` -> `()` + an R32 completion
    assertion (old-form remaining: 0).
 4. ONE call-site cast: the definition lands at line 811 and a 0-arg call sits at 822, so gcc sees
    the prototype and rejects it — `((void (*)(void))func_8012AAAC)()` (§17a-1; gcc folds the cast
    of a known symbol to a direct jal). Only 1 of the 1,386 fleet-wide 0-arg call sites needed it:
    the others see only the `extern ()` decl, which permits a 0-arg call.

DIAGNOSIS NOTE: the failure read CC1-FAIL with only a warning visible under make. Running the
pipeline stage-by-stage (cpp | cc1 | maspsx | jtbl_rodata_pads | as) put it on cc1 rc=33, and cc1's
own stderr named it exactly: "too few arguments to function func_8012AAAC" at line 994. Isolating
the stage was what turned an opaque Error 33 into a one-line fix.

R22 clean-fleet: extract-all 139/139, check-all 140 passed / 0 failed.
family_sweep correctly REFUSED this exemplar (§53: a jr-family must route through
jtbl_family_bank.py; "a 0% from this path would be a TOOL artifact, not a wall") — the ×137 member
sweep is the next step and needs a clean tree, which this commit provides.

Drew T d2a79deff2 feat(phase-29): ALL THREE BEHEMOTHS BANKED — func_80183814 (5,122), func_8017DC1C (1,518), func_8017D2DC (1,586)
Zero functions >1000 ins remain unmatched anywhere in the fleet.

func_80183814 (5,122 ins — the LARGEST function in the game) — round 2 closed it: length 5127->5122
exact, structural residual 36->0, register-sensitive 1201->0, frame -256 -> -0xF8 exact, saves
10 -> .mask 0x807f0000 exact. Verified independently (R14): match_one MATCH (5122 ins).
  ROUND 1's DIAGNOSIS WAS WRONG and the agent refuted it properly: the +5 length was a SYMPTOM, not
  the lever, and the §83d max_reg/cse.c:8340 story does not hold — a 15-line reproducer reproduced the
  case-0/3 CSE exactly (so it cannot be max_reg-gated), max_qty only gates extension ACROSS blocks,
  and the target leaves $s7/$fp unused (no pressure story). Confirmed from a second direction: C01 has
  the identical two groups over the identical symbols with ZERO residual, because a `break` puts a
  CODE_LABEL between them. The two biggest levers were pure DECLARATION SCOPE (§45/§76), not pins.
func_8017DC1C (1,518) — MATCH first round, pin-free, zero __asm__ dials. NOT a jr fn (0 mid-fn jr).
func_8017D2DC (1,586) — MATCH first round (banked in the previous commit).

BANKING ORDER MATTERS — a new failure mode found and worked around: banking func_8017DC1C BEFORE the
carve chain broke the build. Its draft establishes the canon for 39 previously-undeclared externs;
jr_isolate_all's re-partition (overlay_src_split) then DROPPED ALL 39 across the new split boundary
(`D_801C1EB0 undeclared`), leaving them in NEITHER file. The §77 preamble-drop class, in a third tool.
FIX = ordering, not patching: run the §81 carve chain FIRST on a clean tree (gated BYTE-IDENTICAL),
then bank. Reverted, re-sequenced, both banked clean.

R22 clean-fleet 140/140 BYTE-IDENTICAL; tools-health OK; dedup 1886/0; 0 NON_MATCHING (G4).
Fleet: instr 81.6 -> 81.7% · distinct-code 69.1 -> 69.3% · fn-count 89.52%.

Drew T 09b1993059 feat(phase-29): T0.7 sweep (104 members) + BEHEMOTH func_8017D2DC banked (1,586 ins)
T0.7 — the §86 one-member probe applied to the remaining FREE families: 9 LIVE / 6 DEAD / 5 unstaged.
The three highest-value families by raw size (18,084 / 11,234 / 10,880 ins) all probed DEAD — the
probe skipped them instead of burning ~400 gate cycles rediscovering it. Swept the 9 live: 104 banked,
8 of 9 families fully cleared (func_8017BEF8 has 8 stragglers).

BEHEMOTH 2 of 3: func_8017D2DC (1,586 ins, ov_SC01_001) MATCHED and BANKED — closed in ONE agent
round, pin-free. Verified independently (R14): match_one MATCH (1586 ins).
  §81 carve chain: the agent predicted step 1 unnecessary; jtbl_carve REFUSED (the subseg already
  hosts a .rodata carve and the new table's start != span start). The refusal was RIGHT and is the
  instruction to run step 1 — jr_isolate_all --only (2 fns/1 object) -> BYTE-IDENTICAL, then
  jtbl_carve -> BYTE-IDENTICAL, then the ladder banked it.

R22 clean-fleet 140/140 BYTE-IDENTICAL; tools-health OK; dedup 1886/0; 0 NON_MATCHING (G4).
Fleet: instr 81.5 -> 81.6% · distinct-code 69.0 -> 69.1% · fn-count 89.49 -> 89.52%.

Drew T 661f5aa751 feat(phase-29): bank func_8017C730 x ov_SC03_013 (+1,061 ins) via the §81 carve chain
The SESSION-19 handoff's item 1, closed as specified — no drafting, no agent.

- §77 MINIMAL CLOSURE (519 lines, not the 2,993-line whole-file carry): 18 gte_* macros
  + 5 externs + the bandsetup static-inline helper -> match_one MATCH (1061 ins)
- §81 chain, each step byte-gated before the next: jr_isolate_all --only (2 fns/1 object)
  -> BYTE-IDENTICAL; jtbl_carve --func (single-table, 44-piece interleave) -> BYTE-IDENTICAL;
  harvest_verify --chunk 1 -> verified 1 / failed 0, 7042bc71 BYTE-IDENTICAL
- R22 clean-fleet 140/140 from a genuinely clean tree; tools-health OK; dedup 1886/0;
  0 NON_MATCHING (G4). FLEET distinct-code 3,845,161 -> 3,846,222 = 68.3% (+1,061, all
  distinct — a behemoth-class bank, not a propagation); instr-weighted 80.6%
- No §75a class spoke: the exemplar's ApplyMatrixSV(void*,void*,void*) canon fix was
  already carried, so the declarations were clean and it banked first try
- cookbook §77: the ladder CLOSED with all four rungs measured (-56 -> -34 ->
  MATCH-but-uncommittable -> MATCH+BANKED), plus a NEW subsection — the CANDIDATE gate
  and the REAL gate need DIFFERENT preambles (match_one compiles standalone, so a
  shared-type body's CC1-FAIL is a report about the PROBE, not the draft; the types
  header goes in a throwaway probe copy, never in the banked draft)
- FINDING, flagged not acted on (P5d): that shortcut already leaked an ABSOLUTE include
  path into 21 git-tracked files / 23 lines. All 21 verified semantically no-op (guarded
  engine_types.h via engine_core.h at line 2) => removal is byte-neutral, but cpp must
  still find the literal path, so those TUs cannot preprocess on any clone not at
  /home/musashi/bfm-decomp. Invisible to every byte-gate (R34's null-oracle shape, aimed
  at portability). Proposed as the next task.
2026-07-26 11:57:17 -06:00
Drew T 109ce6a2c3 feat(phase-29): BEHEMOTH #6 func_8017C730 BANKED (1,061 ins) + §82 two source-shape oracles
- CRACKED at xHigh and VERIFIED INDEPENDENTLY: match_one MATCH (1061 ins); agent re-matched 3x
  from clean runs (100% register-masked AND register-kept, all 10 regions, frame 0x270 exact).
  §81 carve chain clean first try: jr_isolate_all --only -> byte-identical cacaf7c2 -> jtbl_carve
  (43-piece set) -> byte-identical -> bank -> R22 clean-fleet 140/140, tools-health OK.
  instr 80.6%; distinct-code 3,844,100 -> 3,845,161.
- WHAT IT IS: the matched base func_8017CA80 + camera height-band cull + distance-driven CLUT
  fade. func_8004974C (TransposeMatrix) sits in a 36-ins prologue deriving a Y band; the
  part-level `lim >= g.otz` cull is GONE; flat arms gain an `sz < lim` near-plane cull. The
  base+one-extra-callee fingerprint predicted this exactly.
- §82 ORACLE 1 -- A DUPLICATED `addiu $aN,$sp,K` ACROSS A `jal` MEANS THE BLOCK WAS INLINED.
  `&X` on any non-first local always creates a pseudo and CSE always merges two of them
  (expr.c:6260 ADDR_EXPR -> force_operand(..., NULL); exception: virtual-stack-vars offset 0).
  So the same stack address re-materialised at two sites separated by a jal means CSE was
  PREVENTED from merging => not the same function body. 17 non-inline spellings failed; a
  `static inline` helper reproduced the prologue BYTE-FOR-BYTE first try. Reusable probe: scan
  the ~1,200 built objects for that signature in NON-INCLUDE_ASM functions.
- §82 ORACLE 2 -- SCALAR vs AGGREGATE DECIDES *WHEN* A STACK SLOT IS ALLOCATED: lazily at first
  `&` for a scalar, AT DECLARATION for an aggregate. Six GTE result words had to be six separate
  longs, not a struct, or they don't land after the inlined helper's temps and the frame isn't
  0x270. Second-order: it also flips MEM_IN_STRUCT_P (§30's /s) -- with one word a fixed-address
  scalar, ((PolyF3*)pkt)->rgbc stops aliasing it, so a store needed respelling to keep the
  target's nop. A scalar-vs-struct choice is simultaneously a frame-layout AND an aliasing
  decision.
- BANKING FOOTNOTE (§75a class A): first bank rejected `conflicting types for ApplyMatrixSV` --
  draft (MATRIX2*, SVECTOR2*, SVECTOR2*) vs the TU/fleet canon (void*, void*, void*), 2,286 of
  2,835 sites. Conforming the decl is byte-neutral and banked first try. On a jr function expect
  BOTH gates to speak: the carve chain answers the jump table, §75a answers the declarations.
- Also reproduced: §78 (reuse a busy variable), §80(i) (a lever went -8 -> exactly neutral as the
  base moved), §72 (a register pin made it worse).
- AGENT'S OWN CAVEAT, recorded not hidden: one zero-byte __asm__ keeps a vestigial `mnc = hmid`
  alive that flow.c would delete (costing 10 ins + the 0x130 spill slot). Emits nothing, compile
  is 1061 exact, but it is a documented stand-in -- 12 natural spellings measured, all DCE'd.

Drew T faf4547345 feat(phase-29): func_8017C954 BANKED — jr carve chain cleared; a shared type was PRESENT but INVISIBLE
- BANKED (1,194 ins, ×1 distinct-code). Chain cleared, each step byte-gated before the next was
  built on it: one-line fix to jr_isolate_all._engine_types() -> jr_isolate_all --only
  func_8017C954 (2 fns / 1 object, NOT the bare 47-fn / 21-object resegment) -> BYTE-IDENTICAL
  b7b0d4ae -> jtbl_carve --func func_8017C954 (44-piece carve set + interleave order) ->
  BYTE-IDENTICAL -> harvest_verify VERIFIED BYTE-IDENTICAL -> R22 clean-fleet 140/140,
  tools-health OK. instr 80.5 -> 80.6%; distinct-code 3,842,906 -> 3,844,100.
- THE DEFECT (tools/jr_isolate_all.py): _engine_types() harvested shared type names with four
  patterns -- `typedef ... X;`, `} X;`, forward-decl `struct X;`, fn-ptr typedef -- and a TAGGED
  DEFINITION WITH A BODY matches NONE of them. So `struct PW8017E6D8 { int w; }
  __attribute__((packed));` at engine_types.h:658 was present in the shared header yet invisible
  to the carried-type check, and `extern struct PW8017E6D8 D_801E1EC4;` could not be placed.
  MEASURED BLAST RADIUS: 77 such tags in engine_types.h were invisible. One added pattern fixes
  all 77.
- WHY THIS COST 20 MINUTES INSTEAD OF A MYSTERY BYTE-DIFF THREE PHASES LATER: the Phase-26 audit
  had already turned this predicate's SILENT DROP into a LOUD REFUSAL. The original bug dropped
  4,040 col-0 decls, 683 of them function PROTOTYPES -- and a dropped prototype is a SILENT
  BYTE-CHANGER (C89 implicit `int f()`; return type drives delay-slot fill in this codebase). The
  refusal named the exact symbols and the exact remedy. A loud "I cannot place this" is worth far
  more than a green build -- the audit paying for itself, live.
- §81: the 3-step jr-carve chain + why match_one CANNOT see the problem (it masks jal/HI16/LO16,
  so a jump-table function reports MATCH while the whole-binary gate reports DIFF, correctly).
  Detect with `grep -cE 'jr \$(v0|v1|a0|t[0-9])'` on the target .s + a jtbl_ in asm/<ov>/data/.
  ALWAYS use --only: bare would have resegmented 47 jr-functions across 21 objects.

Drew T 6e9cbda926 feat(phase-29): func_80174CB0 ×3 -> ×135 (§75c pair); the census predicted the residual exactly
- dedup_extend banked 132 / 179 planned across 135 binaries: func_80174CB0 VERIFIED in 132,
  FAILED in exactly 3. 123 ins × 132 = 16,236 ins.
- THE PREDICTION HELD TO THE OVERLAY. The blocker breakdown across the original 134-binary sweep
  was 131 class-B (func_8012F14C arity split) / 3 class-A (func_80012ABC, census 73 s32 vs 7
  s16). Fixing class B alone banked 132 and left 3 -- precisely the class-A set. A diagnosis that
  predicts WHICH members will still fail, and is right, is much stronger evidence than one that
  explains failures after the fact; same shape as §75b predicting that the 3 stuck members would
  be exactly the 3 files carrying the __volatile__ spelling of SHB.
- FLEET: instr-weighted 80.2% -> 80.3% (10,539,723 -> 10,555,959); fn-count 89.14% -> 89.18%;
  distinct-code 67.7% UNCHANGED (propagation moves coverage, not distinct-RE -- fresh cracks are
  the only lever there). dedup 1886 validated / 0 failed, C1 coverage 239,604/239,604.
  0 NON_MATCHING (G4).
- R22 clean-fleet: make clean && extract-all && check-all -> 140 passed, 0 failed of 140.
- cookbook §75c committed with this batch. The 3 residual overlays need the 7 `s16` func_80012ABC
  decls normalized -- worth 3 overlays only, so do it only if trivially cheap.

Drew T 3bbfe21596 feat(phase-29): func_80165CA0 ×3 -> ×135 via ENGINE_SHB; +22 fns ×1; §75b (the carried-#define gap)
- dedup_extend banked 157 / 478 planned across 135 binaries: func_80165CA0 (99 ins) ×135
  (~+0.10pp) + 22 other functions ×1 picked up in the 3 overlays the first sweep excluded.
- FLEET: instr-weighted 80.1% -> 80.2% (10,525,534 -> 10,539,723, +14,189 ins); fn-count
  89.09% -> 89.14%; distinct-code 67.7% (unchanged — propagation moves coverage, not distinct-RE).
  dedup 1886 validated / 0 failed, C1 coverage 239,472/239,472. 0 NON_MATCHING (G4).
- R22 clean-fleet: make clean && extract-all && check-all -> 140 passed, 0 failed of 140.
- §75b — extraction lifts `extern`s but NOT file-scope `#define`s, so a body matched with a macro
  in its preamble compiles only where that overlay's define is in scope ABOVE the splice point.
  Signature is a LINK error (`undefined reference`), never `conflicting types`: an unexpanded
  SHB(x) parses as a call to an undeclared function. The diagnosis PREDICTED the membership —
  the 3 stuck members are exactly the 3 files carrying the __volatile__ spelling of SHB, i.e. the
  function's own preamble still sitting above its own instantiation.
- R14/R35 IN ACTION: the full-sweep census REVERSED the ranking I had just committed. I put the
  class-A normalization first at "~+0.13pp if it reaches ×138"; measured across all 134 it is
  worth 3 overlays (func_80012ABC 3, func_8012F14C 131). The cheap win was the one I ranked
  third. §75a's "collect across the whole sweep before scoping" earned itself immediately.
- NEXT (specified, not guessed): func_80174CB0 is class B on func_8012F14C (1944 `(s32)` vs 968
  `(s32,s32,s32)`). The macro carries the 3-param prototype; the failing TU declares the 1-param
  one FIRST (ov_SC01_001: TU@328 vs instantiation@2616) -> two prototypes, different arity ->
  reject. Per cdecl.compatible's MEASURED rule a K&R `extern void func_8012F14C();` is accepted
  BOTH ways round here (prototype-first + `()`-second always; `()`-first + prototype-second when
  no param default-promotes, and s32 does not) -> it should satisfy both populations in either
  order. One-line probe on the carried decl, byte-gate the 3 members, then extend.

Drew T 39127535da feat(phase-29): func_8014F3E8 ×4 -> ×138 via dedup_extend; §75a enumerates the exclusion classes
- THE NORMALIZATION PAID: one `dedup_extend --binaries <the 134 excluded>` banked 134/400
  planned -- func_8014F3E8 VERIFIED in ALL 134 -> ×138 total (+4,288 ins), no drafting at all.
  A 4-overlay island became full fleet reach because the carried extern finally agreed.
- FLEET: instr-weighted 80.0% -> 80.1% (10,509,526 -> 10,525,534 = +16,008 ins, exactly the
  projected 84×138 + 32×138); fn-count 89.02% -> 89.09%; distinct-code 67.7% (unchanged, as
  expected -- propagation moves coverage, not distinct-RE). dedup 1884 -> 1886 validated / 0
  failed, C1 coverage 239,315/239,315. 0 NON_MATCHING (G4).
- R22 clean-fleet: make clean && extract-all && check-all -> 140 passed, 0 failed of 140.
- §75a — "PROPAGATION-CAPPED" IS AT LEAST THREE CLASSES, and the classifier names which:
    A minority spelling   `conflicting types` + a lopsided census (1710 vs 4) -> normalize, cheap
    B genuine arity split same message, TWO real populations (func_8012F14C: 1944 `(s32)` vs
                          968 `(s32,s32,s32)`) -> the §29 loose-typing wall; a K&R `()` MAY satisfy
                          both but is order-dependent -> PROBE, do not normalize on a guess
    C missing extern      `undefined reference to 'SHB'` -- a LINK error, unrelated to types
  The discriminator is one grep (census the symbol cc1 named) and it decides the remedy.
- R14 self-correction recorded: I predicted func_80174CB0 was "the identical class". It is class
  A in KIND but on DIFFERENT symbols, and different ones per overlay (func_80012ABC at
  ov_SC01_000 where the minority is on the TARGET side; func_8012F14C at ov_SC01_001 = class B).
  One member's error names one blocker, not the blocker set -- collect the classifier's line
  across the whole sweep before scoping a fix.
- func_80174CB0 (×3) and func_80165CA0 stay capped, each now with a named cause and a named next
  probe -- not a wall verdict.

Drew T 10ea5ff653 feat(phase-29): propagate the widen batch — func_8014D4C0 ×138; func_8014F3E8 ×4 (cause measured)
- func_8014D4C0 (84 ins) PROPAGATED ×138: all 138 overlays rebuilt byte-identical, group
  E_func_8014D4C0 registered. 84×138 = 11,592 ins.
- func_8014F3E8 (32 ins) propagated ×4 only (the ov_SC07_{006,007,010,011} island), 134
  overlays excluded one at a time.
- TWO FINDINGS, both measured:
  (1) THE FIRST RUN'S "drop" WAS A FLAG OMISSION, NOT A WALL. Without --recover,
      dedup_propagate takes the historical all-or-nothing path on the first culprit overlay,
      so ONE divergent member cost the whole group (×0). With --recover, Part A excludes just
      the culprit -> ×4 instead of dropped. Always pass --recover on a targeted --addr run.
  (2) THE EXCLUSION CAUSE IS A MINORITY-SPELLING SOURCE OVERLAY, not byte divergence. The
      sigs prove all 138 members share ONE h_exact (2ccf344d), so nothing diverges in bytes.
      The macro carries the source overlay's `extern void func_8014F468(void);` while the
      fleet census is 1,710 `extern s32` + 134 `s32` definitions vs 20 `extern void` + 4
      `void` definitions -- and all 4 `void` definitions are ov_SC07_{006,007,010,011}, i.e.
      the source overlay I banked from is the OUTLIER. The macro inherited the minority
      spelling and silently capped its own reach at that island.
- => the fix is NORMALIZATION (24 occurrences), not a reconciliation engine; the follow-up
  commit flips the SC07 minority to the fleet-canonical s32 and re-propagates.

Drew T ba35785ec4 feat(phase-29): bank func_801777BC (59 ins) x138 — the giv-init base-register lever (§70)
- MATCH (59 ins), real-TU verified by the agent before handing back (cc1 rc=0, 59/59, 0 diffs).
- Propagated x138 with ZERO exclusions -> confirms the ×3 cap on func_80174CB0 was purely the
  carried-extern collision: a body with no externs propagates clean.
- R22 clean-fleet 140/140, 0 failed. dedup-check 1884 validated / 0 failed, C1 coverage complete.
- FLEET CROSSES 80.0% instr-weighted (10,509,526 / 13,141,652); fn-count 89.02%; distinct 67.7%.
- THE LEVER (cookbook §70): residual was ONE instruction, addiu $t0,$t1,0xC vs $t0,$a0,0xC -- a giv
  based on a copy of the param. Reading gcc-2.7.2 loop.c/cse.c proved the natural form can never
  emit the target: cse.c:make_regs_eqv makes the copy canonical (it out-lives a0) and
  loop.c:update_reg_last_use won't extend a0's last-use (giv-init UID >= max_uid_for_loop). Fix:
  walk the PARAMETER itself, so record_initial sees the biv init as hard reg (reg:SI 4),
  valid_initial_value_p accepts it (precondition: no calls), and emit_iv_add_mult bases the giv on
  $a0 -- yielding both required instructions free.
- META: this compiler-source reasoning was done by an ORDINARY Opus 5 drafting agent, unprompted --
  the tier Phase 23 reserved for Fable5. One data point, recorded as such; the cheap action is to
  give routine drafting agents the gcc source path.
2026-07-25 00:49:04 -06:00
Drew T e112eff601 fix(phase-29): find_site — a comment-only line halted the extern scan (§68); func_80174CB0 x1 -> x3
TWO mislabels in one tool, both found by making it print what the compiler actually said.

1) compiles_standalone() returned a bare False and the caller filed EVERY failure under
   "overlay-local TYPE (the real cap)". The dominant real cause is undeclared FILE-SCOPE EXTERNS.
   Now returns (ok, stderr) and the skip is classified by actual cc1 output.
2) find_site()'s backward walk over "preceding contiguous externs" skipped BLANK lines but not
   COMMENT-ONLY lines, so a full-line /* ---- */ between two extern groups dropped every extern
   above it. Comment lines are now skipped like blanks and filtered out of the emitted body so
   make_macro never meets a `//`.

RESULT, measured honestly: func_80174CB0 went from "not self-contained" to a 138-member PLAN, but
--recover banked only x3 (ov_SC07_006/007/011); 135 overlays excluded. Those exclusions are NOT
byte divergence (all 138 share h_exact) -- they are the CARRIED EXTERNS colliding with each target
overlay's own decls. The carry is necessary but not sufficient: it must reconcile per-target-TU
(cdecl.compatible(), the shape reconcile_tu already uses). Spec updated in CURRENT_PHASE.md.

- R22 clean-fleet 140/140, 0 failed. dedup-check 1883 validated / 0 failed, C1 coverage complete.
- fleet instr 79.9% (10,501,384 / 13,141,652); +246 ins from the x3.
- WHY THIS MATTERS beyond the numbers: the Phase-21 backlog already prescribed "macro-extern-
  injection frees them x134 (~+0.3%)" and it was never built, because the mislabel told every later
  session these were the known-hard type wall. A wrong diagnostic label cost ~4 phases.
- cookbook §68. NOTE the exclusion message is ALSO mislabelled ("byte-diverge / irreconcilable"
  conflates differing bytes with a non-compiling instantiation) -- logged to fix.

Drew T 25a02d6940 feat(phase-29): propagate 2 integration banks ×138 — fleet 79.7 -> 79.9% instr, R22 140/140
- func_8012B4B8 (84) + func_80169228 (105) propagated via targeted --addr (--check-only first,
  never --auto-from): 138 overlays byte-identical, 2 new dedup groups, ~+26,082 ins.
- R22 clean-fleet: check-all 140 passed, 0 failed of 140. Fleet fn-count 88.90 -> 88.98%.
- The 3 non-banks are diagnosed, not guessed (blocker_probe, both oracles agree): func_801463A0 is
  a real-cc1 MATCH in its own TU that the gate still rejects (§65c rtu-vs-gate divergence, link-level);
  func_80156670/func_80174CB0 carry "drop when banking" typedefs textually identical to the canonical
  ones. Blockers STACK — stripping the cc1-named typedef exposed the next (S8->B8; MATRIX->a callee
  conflict). Remedy named: strip ALL shared-provided typedefs, then run the DRIVER's ladder.

Drew T 32de37fff4 feat(phase-29): propagate func_80177940 x137 — 138 overlays byte-identical, R22 140/140
- Targeted `dedup_propagate --addr 0x80177940 --recover` (NEVER --auto-from; --check-only first
  confirmed the plan held exactly this one address, so the de-macroize hazard could not apply).
- 138 overlays rebuilt byte-identical; 0 stubs remain for the address; 1 new dedup group registered.
- R22 clean-fleet: check-all 140 passed, 0 failed of 140.

- 5 of the 6 s15 fresh cores propagated ×138 (func_801483E8/8014680C/8017129C/80177AD4/801759D8;
  func_8014A51C §20-capped). R22 clean-fleet 140/140. fn-count 88.66->88.86%, instr 79.4->79.6%,
  distinct-code count 64854->64860, dedup 1879/0.
- EFFICIENCY AUDIT (decision-log): the 2 LLM waves ran 92% match_one MATCH but only ~27% whole-binary
  bank; 6 spot-checked non-banks are ALL match_one MATCH (byte-correct bodies). NOT a missing idiom —
  an INTEGRATION wall (def-side sig / data-extern / unshared struct). We strand ~16 paid-for correct
  functions per wave; a fleet-safe integration-recovery pass would ~3.7× yield for 0 new drafting
  tokens. Next investment = integration tooling, not more drafting. Waves held per Drew.

Drew T f1fd8993bf feat(phase-29): permuter overnight harvest — 29 fresh cores banked + distinct-code 64837->64854
The grinder ran the targeted permuter sweep to EXHAUSTION (all 75 permuter-shaped candidates;
correctly skipped 1575 redraft/structural/integration). It banked 29 distinct functions autonomously
(gate_stage commit=True, byte-gated, fail-closed, §55b un-propagated), 39% conversion.

- All 29 are LOW-REACH (1-5) overlay-unique code in the 0x8017-0x8018 range — confirming the map's
  finding that the permuter-admissible set is the low-leverage tail (the high-reach near-misses like
  func_8014F3E8 close=1 reach=134 are redraft/structural, NOT permuter-shaped).
- Propagation of the 22 reach>1 banks filled only 1 (0x80180710 ×2); the rest are genuinely
  overlay-unique (siblings byte-diverge) — as predicted.
- R22 clean-fleet 140/140 (the 27 overnight per-binary-gated commits verified fleet-wide, §61).
- distinct-code 64837 -> 64854 (+17 unique fns); session total +22 unique (wave +5, permuter +17) —
  the first real distinct-code progress in many sessions. instr 79.4%, fn-count 88.66%, dedup 1874/0.

Drew T 8ea5202135 feat(phase-29): propagate 1 fresh core ×138 + the session's FIRST distinct-code gain
Of the 6 s14 fresh cracks, func_80136F3C propagated ×138 (func_801749C8 dropped as an
ov_SC07_006 straggler; 4 are §20 local-type-capped — future uniquify fodder, low-value
de-duplication per the SESSION-14 finding).

THE POINT (byte-verified): distinct-code UNIQUE count rose 64832 -> 64837 (+5) — the FIRST
distinct-code movement all session. Every other lever today (154-type lift, 6 uniquify cores,
MATRIX rename) was de-duplication and moved distinct-code by 0. These 6 are genuinely UNMATCHED
cores, so banking them ×1 is real new coverage. Percentage is flat (67.6%, denom 87459) but the
direction and the count are the validation the pivot to fresh cracks was correct.

Fleet: instr 79.3 -> 79.4% | fn-count 88.61 -> 88.65% | distinct-code count +5 | dedup 1873/0.
R22 clean-fleet 140/140 BYTE-IDENTICAL.

Drew T 22af9ab2c5 feat(phase-29): 3 Vec8-freed cores ×138, R22 140/140 — and the honest ROI verdict on the cap
- Propagated 0x8012A464 / 0x8014FFDC / 0x801502EC -> 138/138 byte-identical, 0 stragglers, 3 new
  groups. R22 clean-fleet 140/140; dedup 1872/0; C1 237654/237654.
- FINDING (R14/R31): the §20 propagation cap was gating source-level DE-DUPLICATION, not coverage.
  The whole uniquify campaign (Buf+MATRIX+Vec8, 223 files renamed, ~1559 copies stripped, 5
  propagations, 4 R22 cycles) moved the fleet by +6 functions / +558 ins / -6 stubs and 0.00pp on
  all three headline metrics. The freed cores' members were ALREADY matched individually;
  propagation just consolidated them into shared macros. "Unblocked" != "unmatched".
- SESSION ATTRIBUTION: of -837 stubs / +0.3pp instr / +0.23pp fn-count, -831 stubs came from the
  FIRST batch (broad lift -> 13 cores). The uniquify campaign contributed -6.
- Roadmap B4 re-labelled: a maintainability item, not a coverage lever. Remaining camps
  (Handler/Blk8/V8/Prim/Prim_8016E7C8) are small and now known low-yield — opportunistic only.
- distinct-code sat at EXACTLY 3811442/5634875 = 67.6% at open and close. Fresh cracks are the sole
  mover of that number; point the next session there.

Drew T 23b9b57505 feat(phase-29): uniquify+lift Vec8 camps + propagate 0x8012E778 ×138; blocked queue 10 -> 7
Two units, committed together because they touch overlapping overlay .c files.

- PROPAGATE: 0x8012E778 (freed by the MATRIX uniquify) -> 138/138 byte-identical, 0 stragglers,
  1 new dedup group.
- Vec8 UNIQUIFY+LIFT: camp1 {s16 unk0,unk2,unk4,unk6} (8 bytes) x139 files -> Vec8_c1; the 180-file
  {s32 w[8]} (32 bytes) majority keeps the name. These are two genuinely DIFFERENT types that had
  been sharing one identifier across TUs of the same overlay — the case §64a exists for; reconciling
  them to one layout would have merged a 32-byte and an 8-byte struct. Both camps lifted, 319 local
  copies stripped.
- Pre-filtered on an overlay from each camp, then R22 clean-fleet 140/140 BYTE-IDENTICAL.
- Blocked core queue 10 -> 7 (0x8012a464, 0x8014ffdc, 0x801502ec freed). Session arc 13 -> 7 via
  uniquify (Buf -> MATRIX -> Vec8). Remaining camps all small: Handler, Blk8, V8, Prim, Prim_8016E7C8.

Drew T e393c320e6 feat(phase-29): VARIANT camps -> UNIQUIFY (not reconcile); validated on Buf, R22 140/140 (§64a)
MEASUREMENT CORRECTED THE PLAN. The checkpoint called for a "per-camp field-access reconcile";
measuring the camps refutes that: Vec8 = {s32 w[8]} (32B) in 180 files AND {s16 unk0..} (8B) in
139 files; MATRIX 48B/32B/32B; Buf 16B / 0x20+ / DrawEnv. These are DIFFERENT types sharing an
identifier across TUs of the same overlay — reconciling to a canonical layout MERGES them, the
same failure that broke 103 binaries on Prim. The right op is UNIQUIFY: rename the non-majority
camp (byte-neutral — a type name emits no code; TU-local by construction), which makes every camp
single-def and liftable by the existing lift_types rules.

- NEW tools/uniquify_type.py: deterministic camp ordering (file-count desc, then normalized text,
  so re-runs assign the same suffixes); majority keeps the name, camp n -> <T>_c<n>; rewrites ONLY
  files that DEFINE that camp (a file that merely USES the name gets it elsewhere and is untouched);
  \bT\b word boundaries so `Buf` never matches `Buf80153978`.
- VALIDATED on Buf (578/6/1 files): 11 identifiers across 7 files -> 3 camps LIFTABLE -> lifted
  (585 local copies stripped) -> R22 140/140 -> blocked core queue 13 -> 11 (0x8012ea90, 0x801749c8
  freed). Propagated 0x8012EA90 ×138; 0x801749C8 dropped (straggler in ov_SC07_006).
- YIELD, HONESTLY (P9): ZERO new matched functions. fn-count 88.61% / instr 79.3% / stubs 40281 all
  UNCHANGED; dedup 1867->1868, C1 +138. 0x8012EA90's members were ALREADY matched in all 138
  overlays — the propagation consolidated duplication into one shared macro (DRY), not coverage.
  The value is the PROVEN RECIPE + the queue moving 13->11, not the numbers.
- dedup_propagate (R32): the skip line printed a COUNT and no names, and aggregated three unrelated
  causes into n_local — a body skipped merely for a `//` comment (macro-unsafe, 1-line fix) read
  identically to one genuinely using an overlay-local type. Now named and split by cause.
- cookbook §64a (uniquify-vs-reconcile + the validated recipe + remaining camps by cost).

Drew T 3642b5458a feat(phase-29): the type-lift's payoff — 13 cores propagated ×138, −831 stubs, R22 140/140
With the §20 local-type cap lifted (commit:0863), dedup_propagate --auto-from planned 17
self-contained cores that were previously skipped "not self-contained (local types)".

- BANKED: 12 cores via --auto-from + func_80175308 (propagated separately, 138/138) = 13 ×138.
  func_80175308 is the PROVABLE unblock — the core the SESSION-13 checkpoint named as
  local-type-blocked. No claim is made that all 17 were unblocked by the lift; measuring that
  needs a pre-lift re-scan I did not run (P9).
- 5 correctly DROPPED as cross-overlay stragglers (0x8012A018, 0x80172C50, 0x80173A60,
  0x80144090 in ov_SC01_000; 0x801495C4 in ov_SC07_006): h_exact sharing is all-or-nothing and
  those overlays' bytes diverge. --recover NOT used (the documented quadratic thrash hazard).
- GATES: R22 clean-fleet 140/140 BYTE-IDENTICAL (2nd full cycle this session); make report green;
  dedup-check 1854 -> 1867 validated / 0 failed, C1 236964/236964; 0 NON_MATCHING (G4).
- FLEET: instr 79.0 -> 79.3% | fn-count 88.38 -> 88.61% | INCLUDE_ASM stubs 41112 -> 40281 (-831).
  distinct-code stays 67.6% — correct: propagation replicates already-distinct-matched code;
  only a fresh crack moves that number.
- STILL BLOCKED: 13 cores "not self-contained (local types)", blocked by exactly the 8 deferred
  VARIANT entities (MATRIX 3-def, Buf 3-def, Vec8, Prim, Handler, Blk8, V8, Prim_8016E7C8).
  Next lever = a per-camp FIELD-ACCESS RECONCILE, not a lift (lifting them blindly is what broke
  103 overlays earlier this session).

Drew T b3597c08e0 feat(phase-29): 2 §20-unblocked cores propagated x138 (+276) via the type-lift
func_8012B4B8 + func_8012E138 — freed by the Mat32/Cam8012E138 fleet lift
(commit:0859) — propagated x138 (live 138->0 each, +276 stubs). R22 clean-fleet
140/140. No --recover needed (clean h_exact).

decision-log: the §20 type-lift is safely executable when SCOPED to clean types
(lift_types.py + R22); classify-first, lift the 1-def/copy-only-variant types now,
defer the fleet-split variants (MATRIX/Vec8/Buf/M8) to a per-camp reconcile pass.

Drew T 1dd80e9287 feat(phase-29): ov_SC07_006 fresh-138 — 2 cores propagated x138 (+274) + integration-wall finding
Propagation of the 7 fresh-138 cores banked in commit:0855. Only the 2 self-contained
ones cleared all three integration walls:
- func_80130C08 x138, func_80137178 x138 (+274 stubs). R22 clean-fleet 140/140.

The other 5 are blocked, each by a different integration wall (drafting was solved —
all 7 bodies byte-matched; INTEGRATION is the bottleneck):
- func_8012B4B8/func_80175308/func_8012E138/func_8012A1BC: §20 local-type
  propagation cap ("not self-contained") — need build_engine_types type-lift to
  propagate x138 (roadmap B4; ~+552 stubs when unblocked). Stay x1.
- func_80169228: per-member divergence (whole SC03 cluster byte-diverges) — a
  genuine partial family; --recover thrashes it (killed + reverted). Stays x1.

decision-log: fix_header_decl fragility correction (shared multi-caller decls break;
gate_stage's call-site-cast is the integration spine, not header-decl rewriting).

Drew T 7f18dbad2f feat(phase-29): func_8014CD80 x138 — the fresh-138 def-side blocker is RECOVERABLE (R35 reversal)
Bounded probe (SESSION-13, token-free) that REVERSED the same-session "fresh
reach-138 well is spent" verdict. Target func_8014CD80: 138 live, 0 matched, NO
DEFINE macro, a universal body (only universal callees + param offsets, zero
overlay-local D_* refs), clean MATCH draft from batch-1.

- Blocker was a def-side header decl: engine_core.h DEFINE_func_8014CD0C()
  forward-declares it `void func_8014CD80(s32,void*,void*)` while the byte-true
  def is `int func_8014CD80(s32,u16*,u16*)`. gate_stage's arity pre-pass is
  param-COUNT-only (misses return/ptr-type); §54 reconcile_def_sig fixes the
  wrong direction.
- One byte-neutral header edit (void->int, void*->u16*; call site passes u16[3]
  arrays + ignores the return -> codegen unchanged) -> harvest_verify banked x1
  BYTE-IDENTICAL -> dedup_propagate --addr propagated 138/138 overlays
  byte-identical (live 138->0) -> R22 clean-fleet 140/140.
- Fleet 78.7->78.8% instr, 88.22->88.26% fn-count from this one family;
  tools-health green (dedup 1851/0).

Quantified market (decision-log 2026-07-23): of the 75 fresh (>=100-live)
families, 46 carry an engine_core.h caller forward-decl, 38 SIMPLIFIED = the
func_8014CD80 pattern -> each a candidate x138 (~+1.5-2.8pp instr). NEXT: build
tools/fix_header_decl.py + a fresh-family wave. func_80165CA0's 0/135 was a
non-universal BODY (different failure mode), not this blocker.

Drew T 57ef4ebcb5 feat(phase-29): ov_SC07_006 reach-138 batch-1 propagation + live-count re-scope (SESSION-13)
Propagation of the 6 batch-1 x1 banks (§55b: banks committed first in commit:0848,
then targeted propagate as a standalone step):

- dedup_propagate --addr: func_801325B8 -> +3 onboarded-tail siblings
  (ov_SC07_007/010/011). func_8014A048/func_801678F0 byte-diverge in the SC07
  cluster (kept x1); func_8014FE60/func_80167540 local-type-blocked §20 (x1).
- func_80165CA0: consolidated its h_exact subgroup (dedup group registered, +0
  new), then family_sweep --hseq 0/135 — a PER-MEMBER WALL (cf func_80133AB0
  0/136). The x135 "fresh family" prize does not exist here.
- Net batch-1 yield ~9 newly-matched functions; fleet 78.6->78.7% instr, distinct
  flat; ov_SC07_006 84.6->84.8%. R22 clean-fleet 140/140; tools-health 1850/0.

The finding (R14/R35, decision-log 2026-07-23): nins*reach leverage over-counts —
rank by LIVE-siblings. build_wave_args.py --rank live now ranks by the true lever
and reports the fresh(76)/onboarded-tail(44) split. The reach-138 family well is
largely SPENT via wave+gate; the fresh families are the hard tail (def-side
plumbing/DIFF/per-member walls), not free x138 fuel.

Drew T 64bfe59bc0 fix(phase-29): gate_stage gated EVERY non-077 binary against ov_SC01_077's SHA — one-line default, one month
THE BUG (tools/gate_stage.py main(), introduced commit:0181, 2026-06-21, Phase 21 T3):

    good_sha=a.good_sha or DEF_SHA,      # DEF_SHA = ov_SC01_077's locked hash

DEF_SHA is TRUTHY, so it beat run_gate's per-binary lookup
(`good_sha or _check_sha(binary) or DEF_SHA`) and made that lookup DEAD CODE on
every CLI invocation. gate_stage therefore BUILT one binary and compared it to a
DIFFERENT binary's hash: it can never match, every draft reports as "near", and
NOTHING COULD EVER BANK outside ov_SC01_077 from the CLI. A "near" is
indistinguishable from a genuine codegen residual, so the failure looked like a
compiler wall for a month.

WHY IT HID: the programmatic callers take a different path and were all correct —
grinder/idiom_hunt pass good_sha=None (per-binary lookup), lora_grind/bulk_harvest
pass an explicit per-binary sha, orchestrator is 077-only where DEF_SHA is right.
That is exactly why the grinder banked func_80181F78 in ov_SC03_014 (Task 13B)
while my CLI ladder banked 0/10 on the same tree. Two paths disagreed for a month
and nothing compared them (R34's lesson, from the inside).

BLAST RADIUS, MEASURED (not assumed): 0 of 6,708 backlog records come from the
affected path — by source: worker 2724 / bulk-harvest 2275 / lora-grind 766 /
grinder 522, all correct. THE BACKLOG NEEDS NO RE-RUN. The void verdicts are the
manual CLI gates on non-077 binaries, i.e. exactly the Task-5 wave's "the gate
banked ZERO" on 12 preserved cracks — never a codegen finding at all.

FIXED: pass a.good_sha through; run_gate reads config/check.<bin>.sha (R33).
VALIDATED end-to-end: the raw draft that produced {banked:0, near:1} now gives
{banked:1}.

RE-RUN RESULT — 7 of the 12 preserved t5wave cracks are now banked:
  func_8018F694 (478) · func_8019059C (673) · func_80135A4C (181) ·
  func_80135888 (113) · func_80135D20 (100) · func_801749C8 (105) ·
  func_801299C8 (158, was filed "PLUMBING: prototype declaration")
STILL BLOCKED (5, believed genuine): func_8012AAAC, func_80135260, func_801365B8,
func_80165CA0, func_80191C50.

⚠️ SUPERSEDES the earlier retraction: the "0/10 ladder" was not vague interference
— it was the gate comparing against the wrong binary's hash. Task 14 stages 2-3
were priced against a number that could only ever have been zero.

Drew T 52e772628b feat(phase-29): isolate-with-body FIX + 3 more preserved cracks banked (incl. a 673-ins giant)
THE FIX (harvest_verify._jtbl_prep_one): isolate WITH THE BODY STILL SPLICED.
jr_isolate_all accumulates each object's file-scope decls as the new region's
`ambient` set, so partitioning around an INCLUDE_ASM stub hands the region a
DIFFERENT decl context than the draft's body needs — and the gate then produced a
byte-DIFF rather than a compile error, which is why a batch of these read as
"9 compile / 0 bank" and looked like a codegen wall. §61b's law extends one step:
THE CARVE MUST FOLLOW THE SPLICE — AND SO MUST THE ISOLATION.

The un-splice existed only because the tool is stub-centric (a spliced fn is no
longer in corpus.stubs). New _unsplice_body() handles that properly: it finds the
file that NOW holds the body (isolation may have MOVED it into a fresh region file)
and writes back the stub line for THAT subseg, so the gate re-splices identical text.

BANKED via the corrected path (each whole-binary byte-gated, one per invocation):
  func_80135D20  (100 ins, reach 138)
  func_801749C8  (105 ins, reach 136)
  func_8019059C  (673 ins, reach 3 — a giant)
Together with func_80135888 and func_8018F694 earlier: 5 of the 11 preserved
t5wave cracks are now banked.

THE REMAINING 6, honestly classed: 2 genuine DIFF (func_80135260, func_80191C50),
2 CC1-FAIL (func_801365B8, func_80165CA0), 2 §57 self-decl plumbing
(func_801299C8 `prototype declaration`, func_8012AAAC own-name conflict).

⚠️ RETRACTION: the earlier "the ladder converts 0/10, which prices Task 14 stages
2-3" is WRONG and is withdrawn. Three of those ten bank through harvest_verify
alone with the SAME transformed drafts that gate_stage rejected — so that 0/10 was
measuring gate_stage's own interference, not the residuals. Prime suspect is the
arity pre-pass (fix_arity_callers --apply --any-proto edits engine_core.h before
the gate; the §19 regression mode). GATE_NO_ARITY=1 is the ready A/B. Task 14
stages 2-3 remain UNPRICED until that runs.
