feedback5: the co-op browser test reads phase, funds, price, free refreshes and shop slots in one store snapshot when it checks the R refresh — two page reads could straddle the m.private that answers R and pair the new slots with the old funds, failing "host: refresh cost 6 !== 5" under the full pass's load (1 of 4 in full020c; the same check passes alone, "funds 6 → 5"); golden: unchanged (test only)
