`pulumi refresh` sets a temp path under $TMPDIR to `source`

What happened?

Tons of bogus updates seen by pulumi refresh even when no changes have been made to the local files

        ~ aws:s3/bucketObject:BucketObject: (update)
            [id=init.bash]
            [urn=urn:pulumi:main-sin::DayJob.Pulumi::synced-folder:index:S3BucketFolder$aws:s3/bucketObject:BucketObject::i0-init.bash]
            [provider=urn:pulumi:main-sin::DayJob.Pulumi::pulumi:providers:aws::default_5_30_0::3b2ab4b5-9431-4bbe-a2da-a16687d5f515]
            --outputs:--
          - source                   : asset(file:5c2df0c) { r/i0/init.bash }
          + source                   : "/pulumi-asset-5c2df0c1ce4e5c88ed8331e4e85ec29e072c75929c080cdb937635014ae190cf"

I'm on Mac and my $TMPDIR is /var/folders/xf/332s28f116qd_kqfy9rd6rl00000gn/T/

Expected Behavior

no diffs

Steps to reproduce

pulumi up followed by pulumi refresh
