synthetic-unknown-record-type._expectations.md (synthetic)
All files are synthetic, not native session extracts. Pi session JSONL v3 ignores unknown types and diagnoses each type once per file.
Scenario and expectations
Four lines: session syn-sess-urt, brand_new_thing syn-x-1, assistant syn-m-1 with usage 7/3/0/0/10, then brand_new_thing syn-x-2.
- Unknown records produce no events; one unknown_record_type diagnostic per file/type.
- One primary event, syn-m-1; records_seen=4, status=complete.
