Closing this again until I can sort out what on earth the difference is between the packages getting generated with build_style=go vs. what I can build with go get - the former is consistently broken (I had one good build around the time I submitted the package, but it doesn't seem to be reproducible), but the latter works every time.

The way I end up discovering this package is broken is by attempting chamber exec --pristine and then finding out that the --pristine flag wasn't built in. This seems to be because https://github.com/segmentio/chamber/blob/efa34c951185b60996ac983c838d3304bb7a38e2/cmd/exec.go is being built incorrectly, but I can't for the life of me figure out how or why (I've even tried forcing some export CGO_ENABLED=0; unset GOOS GOARCH magic in a local revision of this template, no dice)

If someone else wants to give this a go before I get back around to it, awesome, until then, I've resorted to using the go get version for work.
