The dockeragent credential-store tests keyed their fake filesystem and
path-bearing env seams on POSIX literals, while dockerConfigCredentials
builds candidate config paths with filepath.Join. On Windows every lookup
therefore missed the fixture and the nine credential-expecting
TestDockerConfigCredentials_* cases failed with a nil credential; the
hostagent PULSE_PCT_PATH override test likewise asserted a POSIX path that
is not absolute on Windows. Map fixture keys and env values through
filepath.FromSlash and anchor the override on t.TempDir().
Taken from PR #1755 (ff96aed8c) so the correction lands on main instead of
a parked agent branch. The unified-agent-native Windows x64 job has been
red on every push run since these tests landed on 2026-08-13; the
intervening green runs were pull_request events exercising that PR's own
corrected fixtures.
Contract-Neutral: test fixtures only, no production runtime change.
