DSH 0.2.0-rc.2 v4 native sample with selected fields

The official npm CLI called a real local model in an isolated container with networking disabled. Both CLI runs exited 0. The native compressed file was 17,575 bytes and the decompressed file 51,114 bytes; provenance.json records their digests. This test sample retains only the header, event envelope, turn/step, timestamps, anonymized identities, model and usage. It excludes content, reasoning text, request configuration, tool arguments and original directories. Ordinary non-usage events retain only permitted data fields; this extraction does not verify the complete DSH recovery format.

Sample	Uncached input	Cache read	Total input	Output	Total
Main loop 1	5,572	Unknown	5,572	64	5,636
Main loop 2	34	5,568	5,602	41	5,643
Known sum	5,606	5,568	11,174	105	11,279

There are two calls. Do not add stream usage from the same settlement. pi-ai calculates total itself, so source_total is unknown; cache write, reasoning and cost are unknown. The title API used another 205 tokens, but native data has only the request marker and no result usage: do not invent a third event. Separate synthetic mutation tests cover inheritance, retries, invalid types, limits, incomplete writes and rollback. Those paths have no claimed native samples. Reading the actual native zstd output is recorded separately.
