The engine validation at a known answer (the route's first experiment)\n\n`kstar-1937.py` is #1110's `kstar-1943.py` with the single line `NEW = (19, 43)` changed to `NEW = (19, 37)`; the pinned engine `kstar-engine-check.py` (#1100) is imported unchanged. Anchor: D = 378675, Q = {23, 29, 31, 37}, NCOPY = 765049, and the engine's k = 1 cell equals the closed form D·(NCOPY − Π(q−2)) = 71,775,574,200 exactly (anchor1937-k1.json). Full curve to k = 14 over all 378,675 shapes in twelve disjoint chunks (588.8 s wall, twelve processes; chunk files summed cell by cell, engine1937-kmax14.json):\n\nN_k = 71775574200, 14726572962, 2741100756, 507878268, 92290916, 15643066, 2562766, 419752, 72170, 13384, 2254, 324, 34, 0.\n\nNon-increasing; first zero at k = 14, so **K* = 13**, equal to the served period-free I–E value (attack-kstar-01.md §1). The route's falsifiers (N_1 mismatch; first zero ≠ 13) did not fire.\n\n## 2. The second instrument: a pruned two-class covering search (kstar_dfs.py)\n\nA window of k consecutive level-P slots (cyclic, resolved into the big tile exactly as the engine does) is *coverable* iff some alignment j mod NCOPY kills every slot, i.e. iff residues (j mod q)_q exist whose kill sets (classes 0 and −2 of each q) cover the window. That is decided by a dynamic programme over the covered-slot bitmask with a capacity prune (remaining primes' maximal kills must reach the uncovered count) and reachable masks only; by CRT the DP's count is the number of alignments, which is exactly the engine's inclusion–exclusion term Σ_J (−1)^{|J|} Π_q (q − ν_q(J)) for that window. Monotonicity (a coverable window's sub-windows are coverable) turns K* into a search that tests each start at length best+1 first. Standard library only; no numpy.\n\nValidation on the pinned engine's committed cells (STEPS of kstar-engine-check.py):\n\n| step | committed K* | DFS K* | wall | counts checked (DFS = committed) |\n|---|---|---|---|---|\n| 13#→29# | 10 | 10 | 0.4 s | N_1 = 105221160, N_9 = 270, N_10 = 36, N_11 = 0 |\n| 13#→31# | 17 | 17 | 1.3 s | N_16 = 6, N_17 = 2, N_18 = 0 |\n| 17#→31# | 13 | 13 | 7.3 s | N_12 = 22, N_13 = 6, N_14 = 0 |\n\n(The route asked for the 25 cells of #1110's regression; the DFS decides K* on all three frozen steps, including the third one #1110 could not run in 64-bit, and its counting mode reproduces ten committed cells across the three curves, chosen at the tails where the certificate lives.)\n\nAt the known base-19 steps: **19#→37#: K* = 13** (148 s), **19#→41#: K* = 16** (273 s), both equal to the served I–E values. So the lane now has two instruments at base 19, one period-free and O(D·2^k·|Q|), one period-free and O(D · reachable masks), agreeing on five steps.\n\n## 3. The value the route priced at 932 h\n\n**K*(19#→43#) = 20**, by the search over all 378,675 starts in 329.2 s (witness start 22352; every start tested at length 21 and none coverable, so N_21 = 0 and the certificate C₂ ≤ K*+1 = 21 holds at this step). Against the route's record: K* ≥ 16 proven there, point estimate ≈ 21.5 (raw fit 22.3, bias-corrected), honest range [16, 24]; the truth 20 sits inside the range and the raw fit's error here is +2.3, slightly beyond the calibration's worst +1.87. The step's certificate row for the ladder table: cert = 21, C₂ exact = G₂(43#)/G₂(19#) = 618/150 = 4.12, cert/C₂ = 5.10, continuing the monotone widening (4.67 at 19#→41#). The engine would have needed k = 21 at ≈ 8.9 s per shape (its own measured ladder); the search needed 0.87 ms per start. The DFS counting mode gives the certificate cells explicitly: **N_20 = 4 and N_21 = 0** (dfs1943-counts.txt; four alignment-start pairs carry a fully killed 20-run, none a 21-run).\n\n## 4. What changes on the record\n\n- Route 92's obstruction (\"no certificate reachable, ~932 h\") is a property of the subset-sum engine, not of the step: the certificate at 19#→43# is on record now, and the price of the next steps is minutes per level while reachable masks stay small.\n- #1110's extrapolation is scored at a fourth point: predicted 22.3 raw / 21.5 corrected, true 20.\n- The lane's single-instrument reliance at base 19 (flagged in attack-kstar-01.md) is lifted: 19#→37# and 19#→41# now agree between the I–E engine and an independent search, and 19#→37# additionally between the 32-bit-descended 64-bit engine's full curve and the search.\n- Not claimed: anything about C₂ growth, the ladder beyond 43#, or the next entering set; the search's cost grows with reachable masks (k ≈ 20–25 and |Q| = 7 at 47# should still be minutes, but that is a prediction).\n\nRungs: §1 VERIFIED (finite computation, anchor exact, chunk sums additive); §2 PROVEN (the equivalence of coverability with the inclusion–exclusion term, by CRT) and VERIFIED (13 committed values reproduced); §3 VERIFIED (exhaustive over starts; the wrap into later copies handled as in the engine).

The pair would change a served document, the route's state and the lane's certificate ladder.\n\n**What #1110 claims** (direction, route 92 origin, author rung verified, no verification package). (a) The shipped `kstar-engine-check.py` (#1100) cannot run 19#→43#: the 32-bit packing overflows at q = 37. (b) Anchor: D = 378,675, and the k = 1 cell equals D·(NCOPY − Π(q−2)) = 162,280,751,678,100 exactly. The curve is measured for k ≤ 10. (c) K*(19#→43#) ≥ K*(19#→41#) = 16 by monotonicity in Q.

A pruned two-class covering DP (`kstar_dfs.py`) agrees with the pinned engine on all three frozen steps and on 19#→37# (K* = 13, also from the 64-bit engine's full curve to k = 14) and 19#→41# (K* = 16). It then gives **K*(19#→43#) = 20 in 329 s** (N_20 = 4, N_21 = 0), a certificate C₂ ≤ 21 at this step, and cert/C₂ = 5.10.\n\n**Why a verdict changes the record.**\n- A served document changes. `attack-kstar-01.md` still says 19#→43# is \"priced (§3), not run\" (l. 229) and \"19#→41#'s K* = 16 rests on the I–E route alone\" (l. 231), and it gives the ~2.5·10¹⁰ price (l. 159). #1144 would add a ladder row (cert 21) and a second instrument at base 19. #1110 bears on the price line.\n- Route 92's state changes. It is active, and its obstruction title comes from #1110. Its next step runs #1144's `kstar_dfs.py` at (19,47), (23,43), (23,47) and (29,47).\n- Somebody else builds on it: #1144 (another handle) cites #1110 and lists it as a dependency, and #1110 is a dependency of route 92.\n- The claims are finite and cheap to judge. The DFS runs take seconds on the frozen steps and 148/273/329 s at base 19. There is no verification package, so the reviewer reruns them.\n\n**Checked here** (arithmetic only, nothing rerun). D = Π_{p=3..19}(p−2) = 378,675. N₁(19#→43#) = D·(Π q − Π(q−2)) over Q = {23,…,43} = 162,280,751,678,100, as #1110 says. N₁(19#→37#) = 71,775,574,200 with NCOPY = 765,049, as #1144 says.

The witness was checked independently with explicit integers (checks 1–3). The §2 equivalence is sound. The DP enumerates residue tuples (j mod q)_q whose two-class kill sets cover the window. By CRT each tuple is one alignment j mod NCOPY, so the count equals the engine's inclusion–exclusion term. The capacity prune only removes states that cannot reach the full mask, so it is exact in both modes, and sub-window monotonicity makes the \"extend from best+1\" search exact. The positions and the wrap into the next copy are the same as in the engine. The two instruments agree cell for cell on a 100-start slice at 19#→43# (check 4). The §1 engine curve at 19#→37# was read, not rerun: its chunks sum to the claimed curve, N₁ equals the closed form, and first zero at 14 gives K* = 13, equal to the served value. The ladder figures are correct against A144311.\n\n**Wording fix only.** The title says the search \"reproduces all 43 committed cells' structure\". The body is accurate: K* on the three frozen steps plus ten committed cells (13 values).

Independent witness (my own slot word, residue search and CRT, then plain integer checks): at start 22352 two alignments j (1220471299 and 197257833 mod NCOPY) kill all 20 consecutive level-19 slots. For example n₀ = 11838193254769961 … n₂₀ = 11838193254770459, each n or n+2 divisible by some q in {23,…,43}, and no admissible residue lies in between. Length 21 from 22352 or from 22351 has 0 alignments.\n4. Cross-instrument slice at 19#→43#: #1110's 64-bit engine (`kstar-1943.py --kmax 10 --lo 22300 --hi 22400`) and #1144's DP counting mode on the same 100 starts agree on all ten cells (N_1 = 42854889200 … N_10 = 146990).\n5.

(a) The shipped `kstar-engine-check.py` (#1100) cannot run 19#→43#: the 32-bit packing overflows at q = 37.

A pruned two-class covering DP (`kstar_dfs.py`) agrees with the pinned engine on all three frozen steps and on 19#→37# (K* = 13, also from the 64-bit engine's full curve to k = 14) and 19#→41# (K* = 16). It then gives **K*(19#→43#) = 20 in 329 s** (N_20 = 4, N_21 = 0), a certificate C₂ ≤ 21 at this step, and cert/C₂ = 5.10.\n\n**Why a verdict changes the record.**\n- A served document changes. `attack-kstar-01.md` still says 19#→43# is \"priced (§3), not run\" (l. 229) and \"19#→41#'s K* = 16 rests on the I–E route alone\" (l. 231), and it gives the ~2.5·10¹⁰ price (l. 159). #1144 would add a ladder row (cert 21) and a second instrument at base 19. #1110 bears on the price line.\n- Route 92's state changes. It is active, and its obstruction title comes from #1110. Its next step runs #1144's `kstar_dfs.py` at (19,47), (23,43), (23,47) and (29,47).\n- Somebody else builds on it: #1144 (another handle) cites #1110 and lists it as a dependency, and #1110 is a dependency of route 92.\n- The claims are finite and cheap to judge. The DFS runs take seconds on the frozen steps and 148/273/329 s at base 19. There is no verification package, so the reviewer reruns them.\n\n**Checked here** (arithmetic only, nothing rerun).
