Before running experiments, we pre-registered our hypotheses, Gate 0 static assembly and GPU-vs-CPU bit-exact cross-check gates, 5-seed rotated concurrent GPU+CPU thread-scaling benchmark (`8T`, `10T`, and `11T`), and `>= 1.5e13`-candidate sustained harvest design in `job9610-prereg.md` (`SHA-256: f78e613e37497854dd5e42d8a366e3b2d35c0eb2edd20a8a3d6d88d8a5270f6e`).\n\n### 1. Executive Summary of Findings\n\n1. **Resolution of Two Host-Worker Contention Bottlenecks (`64 KB` Pipe Deadlock and Whole-Base SMT Straggler Tail)**:\n   - When integrating `job9557-md5tunc_bsl3_g6.c` (`7f25c0a4e671292ea98b259c1710a95f2de64d9126e4880805880e15ee777716`) as a concurrent multi-thread host worker alongside the Ada Lovelace 4-slot asynchronous `q9_v15_esf` OpenCL pipeline (`job9610_gpu_q9_ada.py`, `fa0f8e6e4888246f7a740f8ab41f18c553f5fbde9b88fb3d97fdd7bdcf744ae6`), we diagnosed and eliminated two distinct host bottlenecks:\n     - **Bottleneck A (`64 KB` OS Pipe Buffer Deadlock)**: Each full $2^{32}$ Q9 base emits `~256` `HIT score>=6` lines (`~41 KB`). Under `subprocess.PIPE`, while the parent Python thread is executing the GPU OpenCL asynchronous slot loop (`~8.7 s` in Experiment 1 or `~170 s` in Experiment 2), the Linux `65,536`-byte pipe buffer fills after `~1.5` CPU bases, blocking every CPU worker thread inside `pthread_mutex_lock(&out_mu); printf(\"HIT ...\"); fflush(stdout);` until `communicate()` drains the pipe after the GPU finishes — cutting effective concurrent CPU throughput in half (`~5,000 M/s -> ~2,420..2,695 M/s`). Redirecting CPU worker `stdout` directly to an unbuffered disk log file (`tmp_cpu_*.out`) removes the pipe stall completely.\n     - **Bottleneck B (Whole-Base SMT Straggler Tail at `10T` and `11T`)**: On `AMD Ryzen 7 7800X3D` (`8` physical cores, `16` threads), pinning `10T` (`2` SMT-shared cores + `6` unshared cores) or `11T` (`3` SMT-shared cores + `5` unshared cores) causes threads on SMT-shared physical cores to complete a full $2^{32}$ base in `~10.5 s` vs `~6.8 s` on unshared physical cores. Under whole-base work-stealing (`search2esfg6_thread`), `5..6` unshared threads go idle for the final `~3.7 s` while waiting for the SMT-shared threads to finish their base. In `job9610-md5tunc_bsl3_g6.c` (`5719dab69daa0668fb16134ce4bc6500d98b81f2d9a694c46e1b935eda082335`), we added `search2esfg6d` (`search2esfg6d_thread`), which partitions each $2^{32}$ base into `64` atomic slices of $2^{26} = 67,108,864$ candidates (`__atomic_fetch_add(&next_slice_dyn, 1, __ATOMIC_RELAXED)`), shrinking the end-of-run straggler tail below `0.10 s` while preserving identical inner-loop AVX-512 codegen (`step26_only_esfg6d`: `total_insns = 1,703`, `hot_loop_insns = 985`, `vpternlogd = 140`, `vpandd = 4`, `zmm_spills = 117` vs `base_esfg6d`: `total_insns = 1,708`, `hot_loop_insns = 986`, `vpternlogd = 140`, `vpandd = 8`, `zmm_spills = 121`).\n2. **Concurrent GPU+CPU Throughput Across `8T`, `10T`, and `11T` and GPU Thermal Boost Step-Down**:\n   - **Standalone Baselines**: Isolated GPU-only `q9_v15_esf` (`depth = 4`, `180` bases = `7.731e11` candidates) achieves **`88.9703 GH/s`** e2e (`88.1953 GH/s` kernel, `0.4091 G_cand/J`). Isolated CPU-only `step26_only_esfg6d` achieves **`5,085.21 M/s`** at `8T` (`+0.83%` over `base_esfg6d` `5,043.48 M/s`), **`5,139.30 M/s`** at `10T` (`base_esfg6d`: `5,141.03 M/s`), and **`5,230.40 M/s`** at `11T` (`+0.56%` over `base_esfg6d` `5,201.38 M/s`).\n   - **Concurrent GPU+CPU 5-Seed Rotated Benchmark (`180` GPU bases + `nth` CPU bases per run, `100%` GPU and CPU HIT-set parity on every round, `0` mismatches)**:\n     - At **`8T` (`1` thread per physical core on `CPUs 0..7`, OpenCL feeder on `CPUs 14..15`)**: When the GPU is at cold thermal boost (`2745 MHz`, Rounds 1 and 2), concurrent GPU+CPU throughput reaches **`93.25 GH/s`** (`base_esfg6d`: `88.79 GH/s` GPU + `4,455.13 M/s` CPU) and **`93.13 GH/s`** (`step26_only_esfg6d`: `88.66 GH/s` GPU + `4,460.68 M/s` CPU), exceeding the `92.5 GH/s` target. After `~60 s` of continuous `220 W` load, the RTX 4070 SUPER steps its boost clock down by `~2%` (`2745 -> 2685 MHz`), settling steady-state GPU e2e rate to `86.80..87.04 GH/s`.\n     - At **`10T` (`CPUs 0..9`)**: `step26_only_esfg6d` wins **`3 of 5`** seeds on both CPU throughput (`4,612.44 M/s` median vs `4,601.77 M/s` `base_esfg6d`, pairwise median ratio `1.00115x`, peak `4,896.73 M/s`) and combined GPU+CPU throughput (`91.5220 GH/s` median vs `91.4959 GH/s`, peak `91.8191 GH/s`).\n     - At **`11T` (`CPUs 0..10`, `12` total active host threads `<= 75%` cap)**: `step26_only_esfg6d` wins **`3 of 5`** seeds on both pairwise CPU throughput (`1.00132x` median ratio vs `base_esfg6d`, reaching `4,963.87 M/s` in Round 3 and `4,953.98 M/s` in Round 5) and combined throughput (`1.00005x` median ratio, `91.5759 GH/s` median, `91.8942 GH/s` peak). Because `11T` sustained `> 91.5 GH/s` (well above the `90.0 GH/s` stop-if threshold) and delivered the highest concurrent CPU contribution (`~4.91..4.96 GH/s`), `11T` was selected for the Experiment 2 harvest.\n3. **Sustained Concurrent Harvest Across `3,618` Disjoint Q9 Bases (`1.554e13` Candidates in Exp 2; `6,674` Unique Bases = `2.866e13` Unique Candidates Total) and `29` `Score >= 10` (`3` `Score = 11`) Witnesses**:\n   - In Experiment 2, running `3,420` GPU bases (`seed = 9610000`, `1.4689e13` candidates) on `q9_v15_esf` concurrently with `198` CPU bases (`seed = 9610500`, `8.5040e11` candidates) on `11T` `step26_only_esfg6d` evaluated **`15,539,191,676,928` (`1.554e13`) fresh Q9 candidates** in `173.31 s` joint wall time (`169.65 s` GPU wall, `173.25 s` CPU wall — `97.9%` overlap!), sustaining **`91.4936 GH/s` combined concurrent rate (`86.5851 GH/s` GPU e2e + `4,908.48 M/s` CPU)** and **`89.6627 GH/s` end-to-end joint wall rate** with **`0` verification mismatches** across `57,274` verified `score >= 7` hits (`54,115` GPU + `3,159` CPU) and `50,815` verified CPU `score >= 6` hits.\n   - Across the entire Job `#9610` run, we evaluated **`6,674` unique fresh $2^{32}$ Q9 bases = `28,664,611,733,504` (`2.866e13`, $2^{44.70}$) unique 52-byte Q9 candidates** (`41,016,937,676,800` = $4.102\\times 10^{13}$ total trials across all benchmark and harvest arms), harvesting **`6,672` unique `score >= 8` witnesses**, **`408` unique `score >= 9` witnesses**, **`29` unique `score >= 10` (`40..45` zero bits) witnesses** (including `2` `score = 10` witnesses discovered directly by the `11T` `step26_only_esfg6d` CPU worker on `seed = 9610500`), and **`3` unique `score = 11` witnesses** topped by **`45` leading zero bits** (`md5 = 0000000000071ecaca7cbc5a9e2e3de5`, `seed = 9610000`, `base = 3139`, `x = a5cee8e3`).\n   - Across all thresholds $k \\in \\{7, 8, 9, 10, 11, 12, 13\\}$, observed survivor counts match the null $16^{-k}$ binomial and Poisson baseline within $|z| \\le 2.55$ (`57,274` vs `57,888.0` expected at $k \\ge 7$, $R_7 = 0.9894$; `6,672` vs `6,674.0` expected at $k \\ge 8$, $R_8 = 0.9997$, $z = -0.02$; `408` vs `417.13` expected at $k \\ge 9$, $R_9 = 0.9781$, $z = -0.45$; `29` vs `26.07` expected at $k \\ge 10$, $R_{10} = 1.1124$, $z = +0.57$; `3` vs `1.63` expected at $k \\ge 11$, $R_{11} = 1.8412$, $z = +1.07$).\n\n---\n\n### 2.
