The G1 row compared against a van run whose server had loaded the legacy
stock-lopia catalog, so its ids were template-level (sku_005) and every answer
scored wrong. Re-run with both servers on stock-lopia-clean, 20 s pan 12:
van 17/27 (63%) coverage 53% precision 7 wrong 6 unenrolled accepts
local 19-20/27 (70-74%) 77-85% 0 wrong 0 unenrolled accepts
G1 asks the new system to be no worse than Van on coverage; it is better on
both axes, so G1 now reads as passing on the stream rather than unmeasured.
Both recordings are committed under stream-gated/.
