Second instance of the §192 defect class, found by wave Y's ov_SC02_017 slate. The project's own
§37/§124 idiom spells a renamed symbol as `extern s32 gVecX __asm__("D_80126B5C");`, and sym_of's
generic branch matched `__asm__` -- an identifier followed by '(' -- before reaching the real one.
Every aliased declaration therefore collided with every other one under the name `__asm__`.
Measured cost on one slate: 1 byte-verified draft DROPPED and 2 phantom CONFLICTING-EXTERN
failures, on an idiom this same session used to RECOVER work.
NC over src/ plus wave Y's drafts: 1,210 changed verdicts, every one `__asm__` -> the real alias
identifier (899 of them one symbol, aD800B9A02 -- the idiom is fleet-wide), 0 regressions.
13 agents, 63 gap reports: 7 CONFIRMED, 2 REJECTED, 56 already-covered. TWO of the seven correct
laws banked EARLIER THE SAME SESSION, from two independent readers -- the adversarial-verifier
design earning its cost.
§189-A (banked this morning) claimed an interloper between a split constant's lui/ori PROVES the
target wrote two source steps, because the halves are LUID-adjacent and "no statement order and no
pin can put a third constant between them". Byte-refuted four ways: the banked one-statement slice
`prim.col[1] = 0x101010;` compiles with SEVEN insns between its lui and ori; the two-step spelling
§189-A prescribes is BYTE-IDENTICAL (the fix is inert); moving an unrelated statement moves a third
constant in and out of the gap; and one separated pair is 0x88888889 -- gcc's synthesized reciprocal
magic for a `/ 0x3C`, a constant with NO source spelling, making "the target wrote two steps"
unsatisfiable. rank_for_schedule tests INSN_PRIORITY FIRST (sched.c:2395) and reaches the LUID
tie-break only at :2428, so the derivation dropped its equal-priority scope; the real separator is
the BIRTHING BOOST (birthing_insn_p, gated reg_n_sets == 1), which the split pair can never have
because try_split gives its pseudo two sets. Verified off cc1's own -dS dump, which also corrects
the submitting reader: sched1 is a BACKWARD list scheduler, so it is the LUI that sinks, not the ORI.
8 separated pairs across 5 functions in 3 binaries. §189-A's split-TIMING half survives and now
carries a correction banner.
Recovery note: this run was killed by the session usage limit with 3 verifiers outstanding;
resumeFromRunId replayed 10 cached agents and re-ran 3 for 398k tokens vs the original 1.31M.
HARVEST (10 agents, 68 gap reports): 4 CONFIRMED, 3 REJECTED, 41 already-covered. Yield fell from
14 because the readers were seeded with §193 AND §194 AND §195 -- three sessions of laws off the
table before they started, which is the flywheel working.
§197-A IS BANKED AS ONE ENTRY WITH ITS ATTRIBUTION FLAGGED CONTESTED. Two verifiers independently
confirmed the same phenomenon (lhu;sll 16;sra 16+K where the target has lh;sra K) and attributed it
to DIFFERENT passes -- one to cse's fold_rtx associative block with -da dumps showing the middle insn
already gone in x.i.cse, one to combine preferring the count-merge over forming lh. R34 forbids
treating agreement between disagreeing oracles as corroboration, so the observable, the tell and the
cure (a zero-byte asm re-tie; a fresh temp works with no second SET at all) are banked, and the pass
question is recorded as open. Both verifiers independently byte-refuted §136 type-form rule 9's cure:
u16 v[4] and SVECTOR v compile BYTE-IDENTICALLY in rule 9's own context. Banner added at rule 9.
§198 (in the tool's own help text): UNKNOWN was excluded from the default --levers while the wave
PROMPT told every agent "UNKNOWN does NOT mean hard -- it means the atlas could not name a lever."
The tool was silently overriding the doctrine. Measured: UNKNOWN held 607 of 1,179 in-band members,
more than every other lane combined; wave W drew 73 cards from it into 3 gate groups (24.3 drafts per
rebuild vs wave V's 7.8) for 71/71 drafted, 68 banked. Recorded cost: UNKNOWN groups are mostly
singletons, so the free sibling remap yielded ZERO where waves T/U/V got 49/34/25.
Also releases func_80185480 and func_8017EC98 from wave W's spent-card file -- their agents died on
server rate-limiting and no draft exists, so they must not be marked already-waved.
Wave-V token accounting picked this lever: drafting is 88.3% of a wave's output tokens (repair 8.4%,
reconcile 3.2%) at 9.3 match_one compiles per agent, so the leverage is in what a drafter must GUESS
before its first compile. Two such guesses are answered in the tree and were on nobody's card:
callee arity/return type (§195-A: NO positive tell exists in the asm, the procedure is a two-arity
A/B) and global type (every CONFLICTING-EXTERN drop). tools/decl_prior.py indexes 4,162 files ->
67,094 symbols (9,739 with a banked DEFINITION); cards now carry the rows for their own target's
symbols, ranked DEF > TU (authoritative, wave law 2) > FLEET modal + rivals with counts.
Control draw: 63 rows over 10 cards, 83% already settled by the destination TU (still a saving --
the agent was grepping for them by hand), 17% with no local answer at all.
Third instance in one session of the same law (§193-A seed_ref, §194-E tu_ref, §196): the answer was
already computed and the card did not carry it.
344 functions banked (235 gated heads + 108 mechanical siblings + 1 main), fleet 95.9%
instr-weighted / 91.4% distinct / 97.02% fn-count, R22 213/213 from a clean tree after each wave.
The checkpoint records the five results that outlive the count (Reconcile-inside-the-wave, §192's
main-only pre-gate ladder, §193-A/§194-E's dead card pointer, §195-D's invisible internal j, and the
already-covered majority in every harvest) and the next-session order of operations.
32 agents over wave V's 67 index_gap reports: 14 CONFIRMED, 9 REJECTED, 76 already-covered (the
third harvest this session; readers seeded with §193 AND §194 so neither could be re-derived).
THE HEADLINE IS A DEFECT IN OUR OWN VERIFIER (§195-D). masked_diff.mask_for short-circuited on the
OPCODE -- `if (word >> 26) in (2, 3): return 0` -- ahead of the reloc dispatch, so every `j` to a
LOCAL label was dropped from the comparison. The assembler resolves those itself and emits no
relocation, so there was nothing link-time about them. For a loop or switch arm, which label a `j`
targets is the difference between `break` (fall into the shared tail and execute its calls) and
`return` (skip them): byte-proven on ov_SC03_118:func_801825EC, where the banked `break;` and a
call-skipping `return;` variant differ in exactly one word (0800003e vs 08000041) and BOTH reported
MATCH. The blindness reached match_one, the permuter's MaskedScorer, family_cousins.tok and the
atlas similarity tiers at once -- nothing between a draft and the whole-binary gate could see it.
Now the 26-bit field is masked only when reloc_kind == "26" (the linker really does fill it).
R39 control: 35/35 already-banked wave-V drafts still MATCH against their snapshot .s.
Other confirmations of note: §195-A bounds §167-08 with a byte-proven false-negative class (an
argument that DIES at the call is allocated straight into $aN, so its only def is a plain load and
every use reads $aN -- there is no positive tell in either direction, only the two-arity A/B);
§195-B a CALL_INSN does not start a basic block in gcc-2.7.2, so a call-crossing temp can be a
LOCAL-alloc quantity; §195-M frame `vars` is a sequential bump-allocation, unifying §193-I's
CEIL(aggregate,8) term with §165-03/§167-06's 8x-orphan term as one frame_offset walk.
26 agents over wave U's 64 index_gap reports (7 cluster readers, one adversarial verifier per
candidate defaulting to REJECT, seeded with §193 so it could not be re-derived): 14 CONFIRMED,
5 REJECTED, 44 already answered by an existing section (wave T: 9/5/61).
TWO OF THE 14 CORRECT WORK BANKED THE SAME DAY, and both are now cross-banner'd:
* §194-E — `exemplar` is not merely un-banked (§193-A): it names the card's OWN target on 42/73
wave-U and 36/71 wave-T cards, and the `seed_ref` §193-A shipped is same-binary 0/51, so the card
still carried ZERO destination-TU locality. Fixed both ways: a self-pointing exemplar is now
emitted as null, and cards carry `tu_ref` — banked functions in the card's OWN .c ranked by
symbols shared with the TARGET's .s relocations (62% of wave-T targets had such a neighbour vs
19% for the cross-overlay literal grep). Operand-only extraction: a naive uppercase-word regex
read the .s comment column's hex words as symbol names (34 "symbols", 31 of them hex).
* §194-N — §193-D's C dial is misstated: the lever is a SURVIVING CODE_LABEL, not "a label between
the block and the call". jump_optimize deletes any label with LABEL_NUSES == 0 long before sched1
and rewrites a C user label into NOTE_INSN_DELETED_LABEL, which is not a basic-block boundary.
Highlights of the rest: §194-A a zero-byte fence is a one-way wall RELATIVE to the statement being
steered (after = emit-first), and the barrier predicate is volatile-or-colon-less, not the "memory"
clobber; §194-J back-to-back identical stores are deleted by flow.c's last_mem_set unless volatile;
§194-K blinding sched1's alias oracle with a second SET is the first zero-byte dependence-CREATING
lever; §194-M a store in a conditional branch's delay slot proves its C statement DOMINATES the
branch.
