Independent Linux result readback

The retained-composition-replay job in research CI37214051407 passed at research source 83ed57a0d4f2a9cbd58d8e76f859075605b4d10d. It builds clean compiler 38962397144d4418b75f571471225ff02d712617 with Go1.27.1 and runs deterministic, frozen FP32, PTQ and QAT constructions plus saved replays.

We downloaded the job's retained-composition-replay artifact and independently checked its eight response files with the Go observer. verification.jsonl contains those recomputed reports. Each response preserves six current suite frames, one build and five reuses, two native executions per frame, all current record inputs and scores4/4,2/2,1/2 repeated twice. The final label expectation is deliberately different. Original response files remain in the CI artifact.

Across these eight repeated workloads:112/128 named expectations and192/192 record fields. Three fresh model requests make one prediction each; all four saved replays make zero new predictions. This readback establishes this source shape's current finite results on Linux. The macOS paired wall/CPU/RSS comparison remains separate.
