 A separate [WSL CPU Spark GGUF Omni profile](evidence/spark_omni_wsl_cpu/README.md) ran the same pinned Q4_K_M artifact through a Linux CPU-only llama.cpp server and current Omni controller. It passed one warmup and 20/20 serial inventory requests at nearest-rank complete-request wall p50/p95 **7.82/7.97 s**, a public `AsyncOmni.generate` text request, explicit context refusal and in-flight cancellation cleanup with a 4 GiB host reservation. The Linux server omitted the Windows offload-count line; the stage now requires positive CPU tensor-buffer evidence for that log layout and rejects accelerator buffers. This is independent of the earlier WSL vLLM INT8 result and does not qualify incremental streaming or general text quality.
 
+The [hosted Galaxy S24 Spark experiment](evidence/spark_s24_full_attention/README.md) moved one real full-attention decoder layer with a fixed 1,024-token cache shape to the phone NPU. Its W8A16 QDQ QNN DLC inference matched the earlier S25 NPU outputs exactly on one pinned dataset; 100 NPU-attributed component samples had nearest-rank p50/p95 **1.109/1.205 ms**. Separate local FP32 and quantized CPU runs measured the numerical change, with 1.351% hidden-state relative L2 from original FP32 source to S24 output and no task-quality tolerance. AI Hub Workbench runs components on hosted physical devices, not the stateful local Spark generation loop; this cell remains NOT E2E.
+
+The same layer artifact then ran on hosted [Snapdragon X Elite CRD](evidence/spark_xelite_full_attention/README.md) and [SA8775P ADP](evidence/spark_sa8775_full_attention/README.md) NPUs, with exact same-fixture outputs as S24/S25 and 100-sample component p50/p95 **1.433/1.606 ms** and **1.837/2.079 ms**, respectively.

+# Spark-X2.5 attention layer on Dragonwing RB3 Gen 2 / QCS6490
+
+**The hosted RB3 kit (QC Linux 1.6, Hexagon v68) ran one real Spark-X2.5-1.7B attention layer on CPU with near-FP32 numerical parity. A separate W8A8 NPU variant executed but has 20.9% hidden-state relative L2 error on the pinned fixture. Neither variant qualifies full Spark generation.** The [S24 provenance](../spark_s24_full_attention/README.md) pins the FP32 source ONNX, its W8A16 QDQ form, calibration and exact 1,024-token-cache input. The [artifact manifest](artifact_manifest.json) pins downloaded compile outputs outside Git.
+
+Four routes were tested on exact device **Dragonwing RB3 Gen 2 Vision Kit**, using AI Hub Workbench client 0.55.0 and service build in each raw job report:
+
+| Route | Jobs and outcome | One-layer evidence |
+|---|---|---|
+| Reuse S24-built W8A16 QNN DLC `mq9y70k0n` | [Inference](inference_report.json) `j57e4k4lp` and [profile](profile_report.json) `jp4y1m1vp` both failed: `QnnModel_composeGraphsFromDlc: MODEL_GRAPH_ERROR`. | No outputs or timing samples. |
+| Compile same QDQ source for RB3 as W8A16 QNN DLC `mn0g3ye8m` | [Compile](compile_rb3_report.json) `jgnznozrg` passed. Targeted [inference](targeted/inference_report.json) `jglyxoy85` and [profile](targeted/profile_report.json) `j5687r80g` both failed with the same graph error. | Device-specific recompilation did not resolve this graph/runtime failure. It does not establish that all W8A16 Spark exports are unsupported. |
+| Compile original FP32 source to ONNX `mmxj02ljq`, request CPU | [Compile](compile_cpu_report.json) `jglyxowj5`, [inference](cpu/inference_report.json) `jgolrodqg` and [profile](cpu/profile_report.json) `jpvldemk5` passed. All 56 execution-detail rows were CPU. | [Output](cpu/device_output.npz) hidden/K/V relative L2 versus original ONNX Runtime 1.29 CPU was 8.73e-7/2.98e-7/3.37e-7. [Audit](cpu/audit_report.json): 100 samples, nearest-rank p50/p95 19.304/21.113 ms (minimum 19.104 ms). This is explicitly CPU, not NPU fallback masquerading as acceleration. |
+| Compile original source with calibration dataset `d7x8e3d59` using `--quantize_full_type int8 --quantize_io` to QNN DLC `mqkp10ezm`, request NPU | [Compile](compile_w8a8_report.json) `jpyoxq885`, [inference](w8a8/inference_report.json) `jgzlm8yo5` and [profile](w8a8/profile_report.json) `j5wl78z3p` passed. All 61 execution-detail rows were NPU. | [Output](w8a8/device_output.npz) hidden/K/V relative L2 versus FP32 CPU was **20.914%/1.702%/4.413%**. [Audit](w8a8/audit_report.json): 100 samples, p50/p95 5.610/5.761 ms (minimum 5.089 ms). This precision is **numerically unqualified**; no next-token/task tolerance is established. |
+
+All successful jobs used the same fixture dataset `d7m83gjy2` and returned finite FP32 hidden/new-key/new-value tensors. The service `estimated_inference_time` equals each sample minimum, not the median. The [CPU](cpu/audit_report.json) and [W8A8 NPU](w8a8/audit_report.json) audits pin source and fixture hashes, exact job/device/model IDs, output hashes, placement rows and full precision differences. [Submission records](compile_w8a8_submission.json), [initial failed submissions](inference_submission.json), [RB3 W8A16 compile submission](compile_rb3_submission.json), and [CPU compile submission](compile_cpu_submission.json) preserve attempted settings. The scripts [collect existing jobs](../../../../experiments/collect_spark_aihub_component.py) and [audit fallback variants](../../../../experiments/audit_spark_qualcomm_fallback.py) without embedded credentials.
+
+The CPU and NPU numbers are different precisions and outputs, not a qualified speedup comparison. Neither job includes 27 other decoder layers, prefill, continuous decode, KV/ring, sampling, a resident Omni controller, complete-request timing or sustained power/thermal behavior. Workbench is a test facility, not a deployment dependency.
+
+**Matrix status: CPU component numerical pass; W8A8 NPU component execution with unresolved numerical quality; NOT E2E.** The next NPU experiment needs representative multi-prompt calibration and layer/next-token parity gates, then a compatible full-model artifact. The full embedded route also needs device-local state, memory admission, cancellation and sustained profiling. The two W8A16 graph errors remain specific to the tested QDQ export and SDK/device combination.

+**One real Spark-X2.5-1.7B full-attention decoder layer ran on a hosted Samsung Galaxy S24 NPU; complete Spark generation did not.** This is a fixed decode-step component with a 1,024-token full-attention cache, not the 28-layer model, prefill, sampling, a resident KV/ring session or a device-local Omni controller. Qualcomm AI Hub Workbench provisions and releases a physical device for each component job; it is a test facility, not the deployment runtime. ADB still lists no attached device.
+
+The source is the existing FP32 `spark_full_ctx1024.onnx` export from real Spark weights. Its SHA256 is `4e2b1c8d791b1ee0e9b75f3322a20a743c0bf8c40f9b98edd963f2944d6300bb` (205,618,089 bytes); downloading uploaded source model `mn14dw6zn` yielded the same byte-for-byte hash. Workbench [quantization job](quantization_provenance.json) `jg9zne6wp` used calibration dataset `d7x8e3d59` and produced QDQ ONNX source model `mmd5e3v3q`. Its downloaded external-data ZIP SHA256 is `703821ca8ace5672228919ea2add4901def4887748c381b12ffc8b259665c553`; the graph has 92 QuantizeLinear/92 DequantizeLinear nodes, INT8 weight zero-points and UINT16 activation zero-points (W8A16). The original and quantized graphs and the exact inference fixture are stored outside Git under `/home/zhout/project/edge_infer/models/`; the [audit](audit_report.json) pins their sizes and hashes.
+
+The [compile job](compile_report.json) succeeded for exact device **Samsung Galaxy S24, Android 14**, using Workbench client `0.55.0`, service build recorded in the job JSON, target model `mq9y70k0n` and `--target_runtime qnn_dlc --quantize_io`. The old context-binary target was [rejected at submission](compile_legacy_option_rejection.json) by the current API; [Qualcomm's compile options](https://workbench.aihub.qualcomm.com/docs/hub/api.html) list `qnn_dlc` as a current target. The [inference job](inference_report.json) used the pinned dataset `d7m83gjy2` and requested `--compute_unit npu`; its three finite FP32 outputs are [retained](s24_output.npz). The [profile job](profile_report.json) also requested NPU and attributed all 73 execution-detail rows to NPU. Its 100 `all_inference_times` samples had nearest-rank p50/p95 **1,109/1,205 microseconds** (minimum 1,098 microseconds); the separate `estimated_inference_time` field equals the minimum and is not a median. Reported inference peak memory was 210,259,968 bytes. These are component-job figures; they exclude controller, transfers between stages, prefill, all other layers, sampling, loading and sustained heat.
+
+The fixed fixture has FP32 input `[1,1,2048]`, cache tensors `[1,2,1024,256]`, rotary angles and mask. Local ONNX Runtime 1.29 CPU executions of the original FP32 source and downloaded QDQ source produced separate pinned outputs. Relative L2 errors for `hidden` / new key / new value were **1.236% / 0.376% / 0.651%** for QDQ CPU versus FP32 CPU, then **0.555% / 0.0065% / 0.0126%** for S24 NPU versus QDQ CPU. S24 and the prior S25 [NPU output](s25_output_prior.npz) matched exactly on the same dataset ([S25 inference provenance](s25_inference_prior.json), [S25 profile](s25_profile_prior.json)), although they used different compiled target formats and Android versions. These measurements suggest quantization contributes substantially to the source-to-device difference; they do **not** establish next-token or task-quality tolerance. The [audit report](audit_report.json) retains full precision metrics, cosines, artifact hashes, sample statistics and job IDs. The [audit script](../../../../experiments/audit_spark_qualcomm_attention.py) reproduces those comparisons with the downloaded artifacts and fixture.
+
+The matrix remains **NOT E2E**. The next gate is a device-resident, complete Spark prefill/continuous-decode/KV-ring/sampling loop with explicit state lifecycle, numeric token-quality checks, 128-token generation across 512/1024 context transitions, cancellation, memory admission and sustained thermal/power profiling. Workbench component jobs cannot substitute for that local runtime.

+# Spark-X2.5 attention layer on SA8775P ADP
+
+**One fixed-shape attention layer from the real Spark-X2.5-1.7B checkpoint executed on the hosted SA8775P ADP NPU (Android 14). This is component evidence, not complete Spark generation or an embedded Omni deployment.**
+
+The [Galaxy S24 provenance record](../spark_s24_full_attention/README.md) pins the FP32 source ONNX, W8A16 QDQ ONNX, calibration and exact input fixture. Its QNN DLC compile job `jpe7z8l15` produced target model `mq9y70k0n`; the same DLC and fixture dataset `d7m83gjy2` were reused here without recompilation. [Inference submission](inference_submission.json) job `jp1nj7j2g` and [profile submission](profile_submission.json) job `jgdd383eg` both requested `--compute_unit npu` for exact device **SA8775P ADP**. The completed [inference](inference_report.json) and [profile](profile_report.json) reports pin service build, Android version and chipset.
+
+The [three outputs](device_output.npz) were finite FP32 hidden/new-key/new-value tensors at a 1,024-token cache shape. They were bitwise identical to the earlier S24/S25 NPU outputs on the same fixture. The [audit](audit_report.json) measured hidden/key/value relative L2 of **1.351%/0.377%/0.650%** against original FP32 ONNX CPU and **0.555%/0.0065%/0.0126%** against QDQ ONNX CPU. No next-token or task-quality tolerance has been established.
+
+All 73 execution-detail rows in the profile were attributed to NPU. The 100 component samples had nearest-rank p50/p95 **1.837/2.079 ms** (minimum 1.749 ms); the service's `estimated_inference_time` was that minimum, not the median. Reported component inference peak memory was 90,877,952 bytes. These hosted component measurements exclude prefill, 27 other decoder layers, sampling, handoff, loading and a resident KV/ring/controller. They are not paired speed comparisons with other devices or OS builds.
+
+The [audit script](../../../../experiments/audit_spark_qualcomm_attention.py) reproduces the provenance and numerical checks using pinned source artifact paths in the S24 record. The [collector](../../../../experiments/collect_spark_aihub_component.py) retrieves these existing jobs via the local client configuration; neither script contains credentials.
+
+**Matrix status: component NPU inference/profiled; NOT E2E.** Full qualification needs a complete device-resident Spark artifact and Omni backend with prefill/decode/KV-ring/sampling, state, token quality, cancellation and memory admission, followed by sustained power and thermal measurement.

+# Spark-X2.5 attention layer on Snapdragon X Elite CRD
+
+**One fixed-shape decoder attention layer from the real Spark-X2.5-1.7B checkpoint executed on the hosted Snapdragon X Elite CRD NPU (Windows 11 ARM64). This is component evidence, not complete Spark generation or a local Omni deployment.**
+
+The [Galaxy S24 provenance record](../spark_s24_full_attention/README.md) pins the FP32 source ONNX, W8A16 QDQ ONNX, calibration and exact input fixture. Its QNN DLC compile job `jpe7z8l15` produced target model `mq9y70k0n`; the same DLC and fixture dataset `d7m83gjy2` were reused here without recompilation. [Inference submission](inference_submission.json) job `j5wl7876p` and [profile submission](profile_submission.json) job `jg9zmkmlp` both requested `--compute_unit npu` for the exact device. The [raw inference job](inference_report.json) and [raw profile job](profile_report.json) completed. Their service build, OS, chipset and target IDs are preserved in those reports.
+
+The [three outputs](device_output.npz) were finite FP32 hidden/new-key/new-value tensors at a 1,024-token cache shape. They were bitwise identical to the earlier Galaxy S25 and S24 NPU outputs on the same fixture. The [audit](audit_report.json) measured hidden/key/value relative L2 of **1.351%/0.377%/0.650%** against original FP32 ONNX CPU, and **0.555%/0.0065%/0.0126%** against QDQ ONNX CPU. No next-token or task-level quality tolerance has been established.
+
+All 73 execution-detail rows in the device profile were attributed to NPU. The 100 component inference-time samples had nearest-rank p50/p95 **1.433/1.606 ms** (minimum 1.346 ms). The service's `estimated_inference_time` was 1.346 ms, matching the minimum rather than the median. The reported component inference peak memory was 18,423,808 bytes. These are hosted component-job measurements; they exclude prefill, 27 other decoder layers, sampling, transfer, loading and a resident KV/ring/controller. Hardware, OS and hosted power state differ from the mobile runs, so these are not paired speed comparisons.
+
+Re-audit with `benchmarks/edge_harness/experiments/audit_spark_qualcomm_attention.py` and the [pinned source artifact paths](../spark_s24_full_attention/README.md). `benchmarks/edge_harness/experiments/collect_spark_aihub_component.py` retrieves the existing jobs using the local AI Hub client configuration. Neither script contains credentials.
+
+**Matrix status: component NPU inference/profiled; NOT E2E.** Full qualification still needs an X Elite machine running the complete 28-layer Spark model through a resident Omni backend with prefill/decode/KV-ring/sampling, state and cancellation, token-quality checks, memory admission and sustained power/thermal measurements. Workbench is a test facility, not that deployment runtime.

 A [follow-up MiniCPM-o storage experiment](../../../e2e_expansion_20260923/evidence/minicpmo_omni_native_weights_io/README.md) copied the same ten GGUF weights to native NTFS. One warmup plus 20 complete requests passed on Windows CPU (p50/p95 23.62/23.88 s) and Radeon+CPU (16.35/17.20 s), with no prefetch warnings. Separate one-request UNC controls were much slower; the original UNC 20-request Radeon profile remains valid for that path. Run order and OS cache were not controlled, so no causal or cross-placement speedup claim follows. A [real InternVLA Cosmos encoder NPU artifact attempt](../../../e2e_expansion_20260923/evidence/internvla_cosmos_amd_npu/README.md) passed fixed-shape CPU export parity but its tested A16W8 candidates failed the CPU numerical gate or VitisAI compilation; the AMD NPU cell remains NOT E2E.
 
 The [WSL CPU Spark GGUF Omni profile](../../../e2e_expansion_20260923/evidence/spark_omni_wsl_cpu/README.md) adds a separate current-Omni complete-request path to the earlier vLLM INT8 CPU result. It passed two named prompts, 20/20 serial measured inventory requests at p50/p95 7.82/7.97 s, a public text request, context refusal and cancellation cleanup. The CPU-only llama.cpp build required explicit CPU-buffer placement evidence because it omits the Windows offload-count log line. This does not establish token streaming or broad quality.
+
+On a hosted [Galaxy S24 Spark attention-layer experiment](../../../e2e_expansion_20260923/evidence/spark_s24_full_attention/README.md), a real one-layer W8A16 QDQ artifact executed on NPU and matched prior S25 component outputs exactly on one dataset. The 100-sample layer p50/p95 was 1.109/1.205 ms; the service's 1.098 ms estimated-time field was the sample minimum. FP32-source versus S24 output hidden-state relative L2 was 1.351% without a downstream token-quality gate. This adds component C evidence only; device-local generation remains absent.
+
+The same W8A16 layer also ran on hosted [Snapdragon X Elite CRD](../../../e2e_expansion_20260923/evidence/spark_xelite_full_attention/README.md) and [SA8775P ADP](../../../e2e_expansion_20260923/evidence/spark_sa8775_full_attention/README.md) NPUs, with pinned-fixture outputs identical to S24/S25; the 100-sample component p50/p95 was 1.433/1.606 ms and 1.837/2.079 ms, respectively. On [RB3 Gen 2 / QCS6490](../../../e2e_expansion_20260923/evidence/spark_rb3_full_attention/README.md), that W8A16 graph failed QNN DLC loading even after target-specific recompilation. An FP32 ONNX CPU layer then passed with source-relative L2 below 9e-7, while a calibrated W8A8 NPU layer executed but had 20.9% hidden-state relative L2 and remains numerically unqualified. These hosted component outcomes do not establish full generation or comparable device speed.

Across 100 component samples, nearest-rank p50/p95 was 1.109/1.205 ms; the 1.098 ms `estimated_inference_time` field is the minimum, not a median. Relative L2 versus original FP32 ONNX CPU was 1.351%/0.377%/0.650% for hidden/K/V; no token-quality tolerance is known. This is one cache bucket, not 28-layer prefill/decode, KV-ring, sampling, a resident local controller or complete-request timing. ADB has no attached device. | Qualify a complete device-resident artifact/controller with state and token-quality gates, 128-token generation across 512/1024 context transitions, admission/cancel and sustained memory/power; [S24 NPU raw evidence](../../../e2e_expansion_20260923/evidence/spark_s24_full_attention/README.md). |

An FP32 ONNX one-layer CPU route passed with all 56 profile rows on CPU, source-relative hidden/K/V L2 of 8.73e-7/2.98e-7/3.37e-7 and 100-sample component p50/p95 19.304/21.113 ms. A calibrated W8A8 QNN DLC ran with all 61 rows on NPU and p50/p95 5.610/5.761 ms, but hidden/K/V relative L2 was 20.914%/1.702%/4.413% versus FP32 CPU, without a next-token quality gate. These are different precisions, not a qualified speedup; no complete 28-layer prefill/decode/KV-ring/sampling, local Omni controller or complete-request timing exists. | Improve representative W8A8 calibration or find another compatible quality-passing artifact; validate token parity, then full device-resident generation, admission/cancel and sustained power; [RB3 raw evidence](../../../e2e_expansion_20260923/evidence/spark_rb3_full_attention/README.md). |

+The [Spark hosted Qualcomm component expansion](../../benchmarks/edge_harness/results/e2e_expansion_20260923/evidence/spark_s24_full_attention/README.md) advances M1 only to one real fixed-shape decoder attention layer. The same W8A16 QNN DLC ran on S24, Snapdragon X Elite CRD and SA8775P ADP NPUs with identical outputs on one pinned fixture; S25 had prior separate component evidence. On [RB3 Gen 2](../../benchmarks/edge_harness/results/e2e_expansion_20260923/evidence/spark_rb3_full_attention/README.md), the tested W8A16 graph failed QNN loading even after an exact-device compile. FP32 ONNX ran on CPU with near-source parity, while calibrated W8A8 ran on NPU but had 20.9% hidden-state relative L2 and remains numerically unqualified. These are component C results, not full M1: device-local 28-layer prefill/continuous decode, KV/ring, sampling, token quality, admission/cancellation, complete-request timing and sustained power/thermal gates remain open. AI Hub is the test facility, not a deployment dependency.
