| "Full-document and checkpoint values are conservative first-observed polling times from one directional run, not a variance estimate.", |
| "Page 5 and page 10 were observed at coarse intervals and are upper bounds; both diagnostics regressed relative to the saved FP32 checkpoints.", |
| "The table ONNX worker emitted repeated VerifyOutputSizes warnings without page failures; measured wall time includes that logging overhead.", |
| "Browser worker network timing and attributable RSS/GPU allocation were unavailable, so no transfer-time or memory gain is claimed." |

| "reason": "One bounded WebGPU run preserved completion and table-count gates while reducing conservative full-document wall time by 16.13%. The canonical medium profile selects FP16 by explicit product decision and is now published through immutable artifact and release-descriptor commits; the prior WASM memory rejection still applies." |
