Unregistered session.version=“9.9.9-syn-uncollected” uses latest_fallback under V17/V30, retaining compatibility markers instead of rejecting the version alone.
Manually calculated expectations:
- detect=Supported, format_version=“9.9.9-syn-uncollected”, basis=latest_fallback; source_files.format_status has basis=latest_fallback and compat=unverified.
- One latest_fallback diagnostic.
- One imported usage_events record, opencode:part:part_syn_future_1: input_total=9500, output_total=250, total_tokens=9750, source_total=9750. 2026-06-13 summary: call_count=1, input_total=9500, total_tokens=9750.
