Pin ml-in-barcelona/gh-ci-action to a full commit SHA.
The new steps use the third-party action through the mutable tag @v1.0.0. The repository owner can move this tag to other code. An attacker who takes over the owner's account can also move it.
These steps run in the same build job as steps that receive CLOUDFLARE_API_TOKEN, NODE_AUTH_TOKEN, GH_TOKEN, and GITHUB_TOKEN. Code from the action can change the runner state that those later steps use. For example, it can change the PATH, the opam switch binaries, or the npm config.
GitHub's hardening guidance says that a full-length commit SHA is currently the only way to use an action as an immutable release.
Resolve the commit for the reviewed v1.0.0 release. Use that SHA in all three uses: lines. Keep the tag as a trailing comment.

CI sets up OCaml with
ml-in-barcelona/gh-ci-action@v1.0.0, which caches the opam switch on Linux, macOS and Windows, and caches the dune build cache with itsdune-cache/loadanddune-cache/saveactions.make pin/make installsteps, including the Windows retry loops.make pin-listtarget prints the pins once;make pinand CI both read it.make install(--with-test --with-doc --with-dev-setup).The Windows install no longer retries three times; opam still retries downloads (
OPAMRETRIES=10).Risk: two-way door. A revert restores the previous setup steps.
