One native compatibility observation with the public canonical weights

Purpose: use SDK0.2.40's actual research artifact through the new compiler adapter. This is an integration observation. The example has already appeared in the canonical study; its outcomes are not new learned-quality evidence.

Freeze a clean local compiler commit after its checks finish and record that SHA before building. Use Go1.27.2 and the existing, once-verified SDK0.2.40 release download. Do not download, fit or run the original study again.

Inputs:

• example.gooo SHA2568775f9e0f88813e3342faa0fa9c2132e32f70c11f36956e2984853cfba3cef62.
• Canonical model SHA25674abb7c3d8bbc1fa90be22f48cf26cef5e00cbd72cbb8f8689293ce6888a5d37.
• Reuse its eight authored output pairs as both caller construction and native evaluation cases for entry Choose. Preserve its three source condition cases. There are no new independent evaluation inputs in this observation.

Execute once in this order:

1. Build a source-bound local CLI and record its version/build metadata and hash.
2. Inspect the source with the actual canonical model, expecting zero predictions and candidate executions and the canonical source arrays.
3. Construct natively with the model, eight caller cases, the same eight evaluation cases and at most four caller attempts. Retain all JSON and saved source/results.
4. Construct the same source with fixed ordering and the same budget/cases.
5. Replay the saved model construction without supplying a model. If step3 fails, record the dependency failure and do not invent a replay result.

Use separate new output directories. Capture each command, exit status, complete stdout/stderr and macOS time resource output. Do not retry a failed observation. The model's prediction count/timing and the full CLI cost have different scopes. The chosen order and host load are uncontrolled, so elapsed values cannot establish a model speedup. There is no instantaneous computer-wide CPU-utilization sample. Read-only audits and normal regression tests can inspect these retained records.
