The bridge imports msquic.dll by name and nothing ever copied the pinned
library beside the test binary. Linux failed loudly on this. Windows did not
fail at all: DLL search fell through to PATH and loaded an unrelated msquic
from the Windows Performance Toolkit, a tenth the size of the pinned build,
and every scenario passed against it with no sign anything was wrong. The
green result was what hid the defect.
Fixed by mirroring the Linux POST_BUILD copy on the Windows side. Every result
recorded here is from a rerun afterwards, and F1 is now closed on both
platforms.
The open question is how far back this reaches. Every earlier Windows number
in this campaign was measured on this machine, where the copy has never
existed. Those figures are unconfirmed until someone establishes whether the
deleted harness placed the library itself.
