not in the sequence-copy logic itself. It happens before
the test reaches the privilege check: after the test
switches the subscription connection to user=regress_seq_repl,
Windows tries SSPI auth for that login role and rejects it.

I could not run a native Windows SSPI test locally,
but this follows the existing TAP harness pattern
used by tests that authenticate as non-default roles.
The failure occurs because regress_seq_repl is used in
the subscription connection string but is not passed via
auth_extra, so pg_regress --config-auth does not add a
Windows SSPI ident mapping for it.

Meanwhile I'll try to set up a windows machine
and run the test

meson test -C build subscription/036_sequences --print-errorlogs --verbose
