Conversation
Build and run the test suite on Linux and macOS using dune package management, pinned to dune 3.24.0, and check formatting with the ocamlformat dev tool. Scan dune.lock with lmdexpr/dune-lock-osv on lock changes and daily (scheduled runs open/update an issue when vulnerabilities are found). Workflow dependencies, including transitive ones from composite actions, are locked with gh actions-lock. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The standalone fmt job took ~10 minutes: @fmt needs the locked compiler, so it rebuilt the project's compiler on top of the ocamlformat dev tool, and its dune cache never saved because it raced the Linux test job on the same key. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
CI pins dune 3.24.0; align the project's language version (and the generated opam lower bounds) with it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
