forceFullOnFastPath re-issued the NTV2 upload with tryFastUploadCompleted:
false to try to refresh a possibly-expired video resource. Real-machine
testing on a live account + RE of the QQ NT kernel (wrapper.node) proved it
never works:
- the server's fast-path is driven by md5-metadata existence and ignores
the flag (proton omits a false bool anyway); the retry re-fast-paths
- the kernel itself does no validity check — HandleRspUploadV3 trusts the
response's fileExist and goes straight to SendUploadSuccFTN
So an expired-but-still-indexed video resource is a platform-level
limitation, not something the upload flow can refresh. Removing the retry
drops two wasted OIDB round-trips per cached-video re-send. The underlying
#145 (receiver '资源已过期' for a server-expired resource) remains a
platform issue, tracked separately.
Tests updated to assert the single-request behaviour.
