…nned actions) Add .github/workflows/ci.yml with two independent jobs (hence two status checks): - **Build (lake)** — `leanprover/lean-action` installs the toolchain from `lean-toolchain`, fetches the Mathlib cache, and runs `lake build` (which also runs the in-file `native_decide` sanity checks). - **Field-file generators reproduce** — installs PARI/GP, re-runs `scripts/gen_pasta.py` / `scripts/gen_jubjub.py` over their committed outputs and `git diff --exit-code`s `Fields/Pasta.lean` / `Fields/Jubjub.lean`, so a hand-edit can no longer silently drift from its generator. Separate jobs so branch protection can require the build while leaving the PARI/GP-dependent generator check advisory. All actions are SHA-pinned (with `# vX.Y.Z` comments) and checkouts use `persist-credentials: false`. Add .github/workflows/zizmor.yml (`zizmorcore/zizmor-action`, `min-severity: informational`) to audit the workflows for unpinned uses, credential persistence, template injection, and other GitHub-Actions issues — matching `zcash/ironwood`.

.github/workflows/ci.yml— the repo had no CI.Two independent jobs, so they surface as two separate status checks:
leanprover/lean-action@v1installs the toolchain fromlean-toolchain, fetches the Mathlib cache, and runslake build. That also exercises the in-filenative_decidesanity checks (curve points, scalar-mult witnesses, etc.).scripts/gen_pasta.py/scripts/gen_jubjub.pyover their committed outputs andgit diff --exit-codesCompElliptic/Fields/Pasta.lean/Jubjub.lean. This catches a hand-edit to a generated field file silently drifting from its generator (which had happened toFields/Pasta.lean).Triggers on push to
