- 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.
wave_binary over 24 fresh reach-138 ov_SC07_006 families -> 22 match_one MATCH / 2 near.
Whole-binary byte-gate banked 6: func_8014A51C func_801483E8 func_8014680C func_8017129C
func_80177AD4 func_801759D8. R22 clean-fleet 140/140 (engine_core.h reconcile edits verified
fleet-wide, §61).
- The s15 drafter-prompt fix HELD AT SCALE: all 24 winners persisted to the canonical path
(vs s14's 3/24, recovered from transcripts). match_one isolation (per-pid --work) confirmed.
- Consistent integration ceiling: ~22 match_one MATCH -> 6 whole-binary banks (27%), same as s14.
The 16 nears are def-side plumbing / data-extern / struct-def reconcile the gate ladder doesn't
clear; fix_header_decl is off-limits (fleet-blind, §63 UPDATE). Integration recovery is the lever
to improve before the next batch, NOT the drafter prompt.
- 6 genuinely-unmatched cores -> distinct-code movers (propagation follows).
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.
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.
Ultracode wave_binary over 24 FRESH (unmatched, live=138) ov_SC07_006 families -> 20 self-reported
match_one MATCH. The whole-binary byte-gate (sole arbiter, R14/G3) banked 6:
func_8014C6F4 func_801463A0 func_8012B77C func_80136F3C func_80156670 func_801749C8
The gap (20 claimed -> 6 banked) is the integration wall the drafters named: §63 header-decl
(void->s32), data-extern reconcile, struct-guard — a recovery pass follows. R22 clean-fleet 140/140
(the gate_stage ladder's engine_core.h reconcile edits verified fleet-wide, not just per-binary).
These are GENUINELY UNMATCHED cores (unlike the session's earlier propagation work), so once
propagated ×138 they move distinct-code — the metric that sat flat at 67.6% all session.
⚠️ WORKFLOW RECOVERY: the 24 drafters reported MATCH but wrote winners under scratch filenames;
only 3 func_<name>.c persisted. All 24 were recovered from the per-agent transcripts (Write calls
+ Bash heredocs) -> .run/drafts-s14r/. wave_binary.js drafter prompt hardened to force a copy-back
+ existence check as the mandatory final step so a future wave can't lose its winners this way.
Oracle (G1, Ghidra types get, /LIBGTE.H, psyq400.gdt): MATRIX = 32 bytes (short m[3][3] @+0x00,
long t[3] @+0x14, 2B pad after m); SVECTOR = 8B; VECTOR = 16B (long vx,vy,vz,pad).
- HAZARD CONFIRMED: the fleet-wide name `MATRIX` held {s32 m[3][3]; s32 t[3]} = 48 BYTES, not a PsyQ
type at all, while THREE other names (MATRIX_c1, MATRIX_c2, MATRIX2) held the true 32B layout. The
canonical name carried an invention; any future reader assuming PsyQ semantics would be misled.
- FIXED by pure consistent rename across 205 files: 48B invention -> MATRIX_L48 (KEPT — ~131 files are
byte-correct against it, and "fixing" it to 32B would change sizeof/array stride hence codegen);
the true 32B layout now owns MATRIX. R22 clean-fleet 140/140 BYTE-IDENTICAL.
- VECTOR left UNCHANGED on purpose: ours is 12B vs PsyQ 16B (missing trailing pad). I first called it
dead — wrong, it has 1 live use (engine_core.h gte_ldlv0((VECTOR*)sp)). Offsets already agree so a
fix is likely byte-neutral, but it is a LAYOUT change and bundling it with a rename would make an
R22 failure ambiguous. Own R22-gated commit, later.
- engine_types.h gains an oracle-sourced GROUND-TRUTH block: real PsyQ layouts, which of our names are
true vs invented, why MATRIX_L48 must not be "corrected", and the draft-time rule (address-suffix
anything you invent — 7 of the 8 collisions this fleet accumulated were bare generic names).
- SCOPE HELD: renamed + documented; did NOT force existing code onto real PsyQ definitions.
- 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.
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.
- uniquify_type --type MATRIX: camp1 {short m[3][3]; long t[3]} x71 jr-split TUs -> MATRIX_c1;
camp2 {short m[3][3]; short pad; s32 t[3]} x6 -> MATRIX_c2; the 578-file {s32 m[3][3]; s32 t[3]}
majority keeps the name. All three camps then single-def -> LIFTABLE -> lifted (655 local copies
stripped).
- Pre-filtered on one overlay from EACH camp (ov_SC01_000 / ov_SC01_077 / ov_SC06_033) — a
pre-filter is evidence only about what it filtered — then R22 clean-fleet 140/140 BYTE-IDENTICAL.
- Blocked core queue 11 -> 10 (0x8012e778 freed; propagation follows separately per §55b).
- NB: the R22 job was reported by the harness as exit -1 (session fork killed the shell wrapper
after make completed). Verdict taken from the log's terminal "check-all: 140 passed, 0 failed of
140", which is only emitted on completion. Read the gate's output, not the wrapper's exit code.
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).
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).
