ci: harden workflows — timeout caps, pinned+verified elan, drop empty CodeQL language (#153)

hyperpolymath · claude · web-flow · commit 9b11d0831666 · 2026-07-01T13:53:24.000+01:00
## What & why Follow-up to the merged proof-root work (#152), addressing the two CI signals that surfaced on it — both pre-existing and about `.github/workflows/*` (never the proof diff). Scoped to **CI hygiene only**: no licence changes, no removal of security workflows, no un-pinning of actions. ### 1. CodeQL configuration error → fixed `analyze (javascript-typescript, none)` failed with *"CodeQL job status was configuration error."* The repo has **zero JS/TS sources** (TypeScript/Node are banned by the language policy), so the extractor found no code. Dropped `javascript-typescript` from the matrix; kept `cpp`, which covers the real C sources (`impl/elixir/c_src/valence_nif.c`, `impl/ocaml/lean_wrapper.c`, `impl/zig/src/valence_ffi.h`) and already passes. ### 2. Download integrity (Hypatia `download_then_run`, high) `lean-verification.yml` and `rust-cli.yml` installed Lean via `curl … | sh`. Now the elan installer is **pinned to an immutable tag (`v3.1.1`), downloaded to a file, SHA-256-verified, then executed** — no pipe-to-shell: ``` curl -sSfL https://raw.githubusercontent.com/leanprover/elan/v3.1.1/elan-init.sh -o elan-init.sh echo "f5d473c9…75b310 elan-init.sh" | sha256sum -c - sh elan-init.sh -y [--default-toolchain leanprover/lean4:v4.12.0] ``` (Confirmed the pinned script parses `-y`/`--default-toolchain` and self-executes via `main "$@"`, so file execution is equivalent to the old stdin form.) ### 3. Timeout caps (Hypatia `missing_timeout_minutes`, medium) Added `timeout-minutes` to **all 31 `runs-on` jobs that lacked one, across 16 workflows** (found by parsing the YAML, not the truncated bot comment). Reusable `uses:` jobs are intentionally untouched — GitHub disallows `timeout-minutes` on them. Values are tiered by real cost: | Cap | Jobs | |---|---| | 15 | light check / validate / notify / lint / dispatch jobs | | 30 | build / test / proof / scan jobs | | 45 | `verify-idris2` (cold cache bootstraps Idris2 0.8.0 from source, ~20 min) | | 60 | `cflite_batch` (30-min fuzz budget + build/upload overhead per sanitizer) | The `cflite_batch` (`fuzz-seconds: 1800`) and `verify-idris2` caps were deliberately set **above** their known runtimes so the safety cap never cuts a legitimate run short. ## Verification Every workflow re-parsed as valid YAML; **0 `runs-on` jobs remain without a timeout cap**: ``` python3 -c "import glob,yaml; ..." # parse-errors=0 missing-timeout=0 ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01KfgJznd6jzSeDYsSXGAXkU --- _Generated by [Claude Code](https://claude.ai/code/session_01KfgJznd6jzSeDYsSXGAXkU)_ --------- Co-authored-by: Claude <noreply@anthropic.com>
