Develop #

nix develop        # Rust toolchain, uv, git, ONNX Runtime (sets ORT_DYLIB_PATH)
make check         # fmt, clippy, tests
make dashboard-ui  # Node: rebuild the dashboard web app into crates/eukhe-dashboard/web (commit it)
make hooks         # install the git hooks (prek)
env -i HOME="$HOME" PATH="$PATH" USER="$USER" LANG="$LANG" cargo test --workspace  # clean env: inherited EUKHE_* points test daemons at real state

Local CI and git hooks #

Gates run only here, in git hooks. GitHub runs no gate; no pull requests.

mise use -g github:j178/prek@0.5.7  # prek 0.5.7 (https://github.com/j178/prek)
make hooks   # prek install --allow-missing-config --hook-type pre-commit --hook-type pre-push

Hooks (.pre-commit-config.yaml) run under nice -n 10 and unset RUSTUP_TOOLCHAIN (rust-toolchain.toml selects).

Hook Command Checks
pre-commit make ci-fast Staged change: cargo fmt; gitleaks on the staged diff (skipped with a note if not installed); clippy -D warnings on touched crates + dependents (scripts/ci_pr_crates.py; a path outside crates/<crate>/ selects the workspace)
pre-push scripts/ci_local.sh pre-push Pushed commits, in the pushing worktree: cargo fmt; gitleaks on them; clippy and cargo test --no-fail-fast on touched crates + dependents (laws/, proof/, LAWS.bend, PROOF.bend, LAWS.lock, docs, CI and agent files select no crate); scripts/check_laws_wired.py, bend_core.py check and bend PROOF.bend only when a Bend input changed (*.bend, bend/, crates/eukhe-bend/, the gate scripts, scripts/toolchain.env); gate.py --lock-only of the bend skill ($BEND_SKILL, default ~/.agents/skills/bend) when a law or LAWS.lock changed
  • Push from a worktree at the pushed commit. No lock; any worktree pushes any time.
  • A push to a branch other than main (an integration branch) runs only cargo fmt and the secrets scan; the rest of pre-push runs when it merges into main.
  • Skip: a push changing only Markdown in docs/ or the repo root skips pre-push.
  • Needs bend and Lean at scripts/toolchain.env versions, cargo-deny, uv, npm, gitleaks.
  • A failed gate prints its name; fix, rerun.

Nightly gate #

A systemd user timer runs scripts/ci_nightly.sh run at 02:30 UTC: full gate (make ci-local) on origin/main in the gate worktree (<repo>-ci beside the checkout, e.g. ~/Repos/eukhe-ci).

Full gate: fmt; workspace cargo check and clippy; every test unit in 8 parallel shards, clean env, EUKHE_REQUIRE_BEND=1; eukhe-runtime suite; dashboard UI (web/ up to date); bend PROOF.bend and --verdict; cargo-deny; gitleaks on commits since the last release.

  • Green: releases that commit (gh workflow run eukhe-release.yml -f sha=<commit>).
  • Red: no release; a test-breaking commit never ships.
Build-size rule Why
Each nightly run starts with cargo clean in the gate worktree Cargo never deletes stale build files; one day of runs grew the build dir to 410 GB
Full gate: CARGO_INCREMENTAL=0 One build; incremental files only add size
Full gate: CARGO_PROFILE_DEV_DEBUG=line-tables-only Failed tests still show file and line; full debug info is several times larger
Tests keep these two settings Tests reuse the gate's build; other settings double the size 
make nightly          # run the nightly gate now
make nightly-status   # result of the last run
  • ~/.eukhe/ci/nightly.log: each run's result; on failure, failed gates and test units.
  • ~/.eukhe/ci/nightly-last.log: full output of the last run.

GitHub runs one workflow: the release.

Releases #

  • The nightly gate starts .github/workflows/eukhe-release.yml for the passing commit. Urgent release of a commit that passed make ci-local: run it by hand (workflow_dispatch with sha).
  • Version: next patch of the Cargo.toml series ([workspace.package] version = "X.Y.0"): 1 + highest patch among tags eukhe-vX.Y.P, or 0 for a series' first release.
  • Tag eukhe-v<version>, title Eukhe v<version>, marked latest, pinned for the flake in nix/release.json.
  • New series: set the workspace version to the next X.Y.0 (e.g. 0.11.0, 1.0.0).
  • Stops the release: a workspace version not X.Y.0, a tag of a newer series, or a version number of more than 6 digits.
  • eukhe-next-version (crate eukhe-build-info) computes it: the rule bend/semver.bend runs as compiled Bend (entry bend/ffi_semver.bend, eukhe_bend::rules::semver); laws laws/semver.bend (R1 the rule, R2 the entry), proved in PROOF.bend. The build script checks EUKHE_RELEASE_VERSION with the same rule.
