Someone elsewhere suggested a lockfile, which seems a pretty obvious solution in hindsight. I'm fine with commit hashes, but the UX is terrible and consists of pasting the action into into StepSecurity's thingie, when this is something that GH should have built in.

commit hashes are immutable, and your own commit history can serve as the lock file.

but if you're targeting a commit hash directly, it's already locked. Lock files are for mapping a version range to a real life version number. Lock files are useless if you pin the exact version for everything.

Sure, it's just that the DX of getting that commit hash isn't terrific, so one might be more inclined to trust an auto-update bot to automatically update them instead. A lock file is more like TOFU on a tag. I'd also take a UI like a "bake" button and CLI flag that substituted the hashes automatically, but you just know people are going to build `--bake` right in to their automation.

Another solution would be to implement immutable tags in git itself, but git upstream has so far been hostile to the whole concept of immutability in any part of git.
