[luv-legion-725] Cut CI wall clock from ~4min to ~1.7min, and bound the jobs that can hang

[NiveditJain]

Prompted by run 32228816396, where the x86_64-unknown-linux-musl daemon leg sat in apt-get update for 25+ minutes with v1.0.1 blocked behind it — while the arm64 leg ran the identical step and finished the whole job in 1m49s. That is a stalled Azure mirror, not a real cost, and the reason it could hold a release is that integration-suite.yml:68 held the only timeout-minutes: in the repo.

Measuring around that turned up three structural costs in ordinary PR CI. Baseline numbers are from run 32227503128 (a normal green PR) and the live cache API.

Result

Measured on run 32233857769 — and this is the worst case, because the PR edits ci.yml, which is deliberately in both new path gates, so rust-quality and docs both ran in full and rust-cache was still cold (it only writes on a push to main).

Job	Before	After
rust-quality	3.9m	2m23s
test (hook-log-file)	2.7m	1m36s
test (default)	2.2m	1m33s
test (log-debug)	2.2m	1m26s
quality	1.4m	54s
docs	1.4m	1m1s
build	1.0m	47s
test-e2e	0.9m	36s
wall clock	4.0m	2.4m
runner-minutes	15.7m	10.3m

A TypeScript-only PR skips rust-quality and docs entirely, and a warm rust-cache cuts the restore further, so steady state lands well below this.

What was wrong

1. bun install ran a full Next.js production build, in 6 of 8 jobs. package.json's prepare is bun run build, which bun fires as an install lifecycle hook. Straight from the build job log:

$ bun install --frozen-lockfile
$ bun run build
  ▲ Next.js 16.3.1 (Turbopack)
  ✓ Compiled successfully in 14.2s
    Finished TypeScript in 13.4s

That is the entire 25–33s "Install dependencies" step. rust-quality has passed --ignore-scripts since it landed and installs in 1 second — the control that proves it. translate-docs.yml already guards the same way, with a comment naming this exact hazard. build paid it twice (its own Build step then re-ran the same thing warm in 7s), and publish.yml paid it twice more per release.

2. The cargo cache cost more to move than the work it replaced. One cargo-Linux-* entry had reached 5,727 MB — 57% of the repo's whole 10 GiB quota in a single key, so the store stayed in permanent LRU eviction — and restoring it was 127s, against the 74s cargo test it existed to avoid. path: target archives every intermediate the workspace ever produced, including this workspace's own crates, which recompile in seconds and are the likeliest to be stale. The comment at ci.yml:153-172 documents getting burned by this and fixed the multiplication across refs; the size is what was left.

3. rust-quality ran in full on every PR, including pure-TypeScript ones. Its Detect crates gate was written for a stage-1 empty workspace; all three crates exist now, so it had been answering true unconditionally. It is the longest job in CI, so it set the wall clock for every PR.

4. 190 of 208 unit test files built a jsdom they never touched. The config set environment: "jsdom" globally for the sake of 16 React files and two more that already opt in per-file — and the test matrix runs the suite three times, so it was paid three times per run.

What changed

• --ignore-scripts on every bun install in ci.yml (6) and publish.yml (2). In cli-tarball this also fixes a latent wart: its prepare build ran before npm version, baking the pre-bump version into dist/ before the explicit Build step threw it away and redid it.
• Swatinem/rust-cache@v2 replaces both hand-rolled cache pairs, keeping the existing save-only-on-main / never-from-a-PR gates.
• Changed-paths gates on rust-quality and docs. fetch-depth: 2 plus git diff HEAD^1 HEAD — on pull_request, checkout builds the merge commit, whose first parent is the base. No new job, no needs: edge, nothing serialised; the job still reports a status. push is never gated, so main always gets the full check and keeps the cache warm.
• vitest split into node/dom projects on the file extension. jsdom construction 40.96s → 13.67s measured locally. A new .test.tsx still gets a DOM automatically; the per-file // @vitest-environment jsdom docblock (already used by two files) remains the escape hatch, and client-telemetry.test.ts now carries it because the module under test reads window.location.
• timeout-minutes on every job across ci.yml, publish.yml, build-daemon.yml, osv-scanner.yml, build-image.yml.
• The apt step is bounded, retried, and tries the install before the refresh (see below), and loses -qq, which was hiding which mirror stalled. musl-tools stays: -p failproofaid reaches rusqlite with bundled and ring through rustls, so the cc crate needs musl-gcc on both musl legs.
• concurrency groups on build-daemon.yml (scoped to pull_request, so the workflow_call legs that are a release's binaries are never cancelled), osv-scanner.yml and build-image.yml.
• mintlify pinned to 4.2.680 in ci.yml, matching translate-docs.yml — floating meant an upstream release could redden a branch that changed nothing.
• Bun cache is restore-only in 5 of 6 jobs, with quality the single writer. All six shared one read-write key, so all six raced to upload the same 401 MB entry and five of them lost.

Two things the first CI run found

Both are recorded because they are the kind of thing that would otherwise be re-learned.

nick-fields/retry cannot bound a sudo command. That was the first version of the apt fix, and CI rejected it. The action bounds a step by killing its process tree as the runner user, and apt runs as root — so the 4-minute timeout fired exactly as designed and the action then died with kill EPERM instead of retrying, converting a recoverable stall into a failed leg. sudo timeout puts the killer on the same side of the privilege boundary as the process it must kill. That run also confirmed the stall is reproducible rather than a one-off: every azure.archive.ubuntu.com line came back Ign, apt fell back to archive.ubuntu.com, fetched the InRelease files and then sat 3.5 minutes emitting nothing. So the step now tries apt-get install before apt-get update at all — the refresh is the part that stalls, and the runner image's lists usually make it unnecessary. Verified on the passing run: update never ran, and the whole step took 46s.

The test job genuinely needs dist/index.js. The custom-policy loader tests resolve import ... from 'failproofai' through findDistIndex(), which prepare had been building as a side effect. The job now builds that one bundle explicitly — ~3ms against the ~28s it replaces. Worth recording how it got through: running the whole suite with dist/ moved aside passes, because an earlier test writes that file before the loader tests read it; only running them alone fails. Test-order luck read as a clean verification.

Verification

• Unit suite green (208 files / 3864 tests) both in full and with the dist-dependent files run in isolation against only the fixture bundle — the check that would have caught the loader dependency the first time.
• E2E green (316 tests) after only the three bun bundles, no Next build. cli.mjs/worker.mjs were previously left behind by prepare, which the standalone __tests__/e2e/layout/*.sh fixtures quietly relied on.
• lint 0 errors (5 pre-existing <img> warnings), tsc --noEmit clean.
• Both path gates' greps tested against representative path lists, including decoys — scripts/Cargo.toml.template and docs/Cargo.toml.mdx correctly do not trigger the Rust gate.
• 11 drift guards in release-pipeline.test.ts: every job carries a timeout-minutes, no bun install omits --ignore-scripts, no cache archives a bare target path, and the apt step is bounded by a killer running as the same user apt does (asserting the sudo timeout ordering specifically, since the reverse is what failed). None of these regressions turns CI red on its own, which is exactly why they need a test rather than a convention.

Still to confirm post-merge: the new cargo cache entry's real size, and that a crates/** change still fires both rust-quality and build-daemon — the paths gate failing open is the one way this could silently drop coverage.

📝 Walkthrough

Walkthrough

The pull request adds workflow concurrency and timeouts, narrows Bun and Rust caching, bounds musl installation retries, skips lifecycle scripts, gates Rust and documentation checks, splits Vitest environments, and adds CI safeguard tests.

Changes

CI reliability and validation

Layer / File(s)	Summary
Workflow controls .github/workflows/build-daemon.yml, .github/workflows/build-image.yml, .github/workflows/ci.yml, .github/workflows/osv-scanner.yml, .github/workflows/publish.yml	Workflows now use job timeouts and controlled concurrency.
Cache and installation controls .github/workflows/build-daemon.yml, .github/workflows/ci.yml, .github/workflows/publish.yml	Rust and Bun caching is narrowed. Musl installation uses bounded retries. Dependency installs use --ignore-scripts.
Conditional validation and fixtures .github/workflows/ci.yml	Rust and documentation jobs detect relevant changes. Test and E2E setup builds required fixtures.
Vitest environment split vitest.config.mts, __tests__/lib/client-telemetry.test.ts	Vitest separates Node and jsdom projects. Telemetry tests explicitly use jsdom.
CI safeguard regression tests __tests__/ci/release-pipeline.test.ts, CHANGELOG.md	Tests validate workflow safeguards. The changelog records the CI changes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 7d4b6

The new Rust CI gate can skip the daemon/worker protocol test when only worker TypeScript files change, allowing a worker regression to merge without exercising the affected contract. Merge should wait for the gate to include those paths or for an explicit owner acceptance of that coverage gap.

This was a duplicate of my review overview. The one I maintain is above.

[hermes-exosphere]

Hermes found blocking issues that should be addressed.

High: Run the daemon/worker integration test for TypeScript worker changes

• Rule: COR-001
• Location: .github/workflows/ci.yml:163
• Evidence: The new gate at .github/workflows/ci.yml:163 runs cargo test only for crates/, Cargo files, rust-toolchain.toml, or ci.yml changes. However crates/failproofaid/src/server.rs:477-554 defines a real end-to-end test that starts bin/failproofai-worker.mjs and verifies a policy deny response. A change limited to the worker or its TypeScript policy implementation therefore skips this test. If such a change alters the hookResult shape (for example removes exitCode), the Rust daemon rejects it as BadResponse and returns an error to hook clients instead of a verdict.
• Required change: Include the TypeScript worker entry point and its runtime dependency paths (at least bin/failproofai-worker.mjs, src/hooks/, and relevant lockfile/package inputs) in the rust-quality gate, or split this live IPC test into a separately path-gated job that runs for either Rust or worker changes.

High: Run the daemon/worker integration test for TypeScript worker changes

• Rule: COR-001
• Location: .github/workflows/ci.yml:163
• Evidence: The new gate at .github/workflows/ci.yml:163 only matches crates/, Cargo inputs, rust-toolchain.toml, and ci.yml. A PR changing only bin/failproofai-worker.mjs or src/hooks/ therefore sets present=false and skips cargo test. That suite contains a live test at crates/failproofaid/src/server.rs:477-550 which starts bin/failproofai-worker.mjs; the worker imports src/hooks/worker-server at bin/failproofai-worker.mjs:37. Consequently, a worker-only protocol regression can merge without executing the only end-to-end Rust-to-worker contract test.
• Required change: Expand the gate to include bin/failproofai-worker.mjs, src/hooks/, package.json, and bun.lock (plus other worker runtime inputs), or move the live IPC test to a job gated by either Rust or worker changes.
