Summary

• Attribute the Ascend guide to the original 310P3 / CANN 9.1.0-beta.1 / torch_npu 2.10.0 report and the four reported model pipelines.
• Explicitly distinguish the revised CAM++ pooling snippet's CPU-only equivalence checks from NPU validation, and separate later Nano/Qwen3 loading failures from SenseVoiceSmall timing reports.
• Replace blanket cold-start/compatibility assurances with bounded correctness and cold/warm timing checks. Preserve every executable snippet, install/device section and section heading.
• Add two documentation regressions to the existing model-free documentation CI list; no workflow or runtime changes.

Context: #3708, particularly the later reports summarized in #3708 (comment).
This clarifies scope; it does not close or claim to fix those reported runtime problems.

Validation

• RED: both new cases fail on the unchanged guide; eight existing reference-documentation cases pass.
• GREEN: 325 model-free documentation cases pass, zero skips, three existing explicit deselections. The command matches the existing Product site model-free contract selection.
• Build 117 product pages; validate 206 pages.
• All four fenced code blocks byte-identical. Installation/device sections and all section headings unchanged. Exact two-file change checked across 4,173 tracked blobs.

The initial broad local run retained two failures from an SSH_CLIENT-triggered DSW shell banner polluting the unchanged curl recipe tests' JSON stdout. A minimal reproduction isolated that environment effect; the successful run removes only SSH_CLIENT from test-child environments. No shared configuration or repository test assertion was changed to hide it.

Not a full repository-suite or NPU hardware/ASR-quality acceptance. No model downloads, Nano experiments, dependency updates or runtime changes. Exact-head hosted CI is required before normal merge.
