Every .github/, Cargo.toml and unknown-path change selected all checks, including the six goreleaser builds, two of them on macOS. Over the last 30 days that was 127 of 449 main commits.

Release contracts now run for release config and scripts (the existing release-artifacts-needed.sh list) and for core/Cargo.lock, since a new native dependency is what breaks a cross-compile. Everything else that used to select every check still selects every other check. Replaying the same 449 commits selects release contracts on 42.

Summary by CodeRabbit

  • Chores
    • CI now separates standard checks from release-contract checks. Changes to release inputs or the core dependency lockfile trigger release-contract checks; other changes generally run standard checks only.
    • Changes to CI workflow configuration continue to trigger all checks, and manual quick runs now use the standard check set.
    • Updated CI selection tests to cover these scenarios.

Walkthrough

CI job selection now distinguishes normal checks from release-contract checks. Standard paths and manual quick runs select normal checks. Changes to core/Cargo.lock or detected release inputs add release-contract checks. Routing tests reflect these rules.

CI job selection

Layer / File(s)Summary
Job selection rules
scripts/ci.py, scripts/test-ci.py
The selector defines normal checks and uses them for standard paths and manual quick runs. It adds release-contracts when core/Cargo.lock changes or the release-artifact script detects changed release inputs. Tests cover these selection rules.

Priority: โž– Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other


Merge Risk: ๐ŸŸก Moderate ยท up to 019de

Changes to the release-contracts job can pass CI without running it, allowing broken release checks to reach main. Address that routing gap before merging.

Security Architecture Review

Security architecture risk: ๐Ÿ”ต Low ยท up to 019de

The change reduces early release validation without changing release-publication prerequisites or credential permissions. Mandatory routing checks remain in place. Risk is limited, but repository-level merge enforcement could not be verified.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred โ€” The directly affected boundary is repository-wide CI validation routing, including Linux and macOS release builds. The inspected comparison does not expand tenant, production-service, or publication authority.

Security Findings and Attack Paths

  • inferred โ€” A helper returning false can omit release builds from early CI, but a blanket false result would fail mandatory routing assertions. Executing PR-authored selection policy predates this PR, and publication independently requires release validation. These countercontrols limit the helper-edit scenario; a newly introduced publication bypass was not established.

Trust Boundaries and Controls

  • observed โ€” The release-contract caller retains contents-read and actions-write permissions with inherited secrets. Cache credential selection still restricts write credentials and cache saving to main pushes, with read credentials or fallback behavior for other runs. These authority settings are unchanged by the PR.

Resilience and Maintainability Implications

  • observed โ€” Git or helper process failures exit selection unsuccessfully. The aggregate rejects failed selection, invalid job lists, missing contracts, and any selected job that fails, is cancelled, or is skipped. Successful or skipped results are accepted only for unselected jobs.

Hardening Proposals

  • proposed โ€” Consider conservatively selecting release contracts when the release-routing helper itself changes, independently of that helper's answer. This would contain future policy drift rather than remedy an established publication vulnerability.

P1 Badge Run release contracts for changed Cargo manifests

When core/Cargo.toml or a crate manifest changes without changing core/Cargo.lock, this branch now selects only NORMAL, even though manifests directly control release builds. For example, changing [profile.release] or enabling an already-locked dependency feature can break the musl/ARM/macOS builds exercised by .github/workflows/release-contracts.yml, while the normal jobs only run Linux tests and cargo check on macOS. Include release-affecting Cargo manifests in the release-contract selection rather than relying exclusively on the lockfile.

Useful? React with ๐Ÿ‘ย / ๐Ÿ‘Ž.

Valid. Fixed in e65bf7660: any core/**/Cargo.toml change now selects release-contracts alongside core/Cargo.lock, with test cases for core/Cargo.toml and a crate manifest. Replaying the last 30 days of main, this adds 5 release-contract runs (42 to 47 of 449 commits).

Independent verification

PASS+NOTES at 019ded721

  • test-ci.py OK, actionlint clean. Release inputs (release-contracts.yml, release.yml, .goreleaser.yaml, verify-release.sh, ...) still select release-contracts, both on their own and alongside .github/ changes. ready is unchanged and accepts a skipped, unselected release-contracts. An empty diff selects only contracts.
  • Coverage gap: a core/Cargo.toml edit without a lockfile change no longer selects release-contracts. Examples: [profile.release] (core/Cargo.toml:32) or feature flags, which affect the musl/darwin release builds. The same goes for ci.yml edits to the release-contracts call (secrets/permissions). These will now surface first at tag time. Consider adding core/Cargo.toml next to core/Cargo.lock at scripts/ci.py:26.
  • Crash on huge diffs (scripts/ci.py:31-33): select now passes every changed path as argv to one bash call. Around 25k+ paths, it raises OSError E2BIG, changes fails, and CI goes red. I reproduced this with 40k paths. The old code called the script once per unknown path and never hit this. Unlikely, but cheap to fix: pre-filter to the known release-input names, or test membership in Python.
  • CI: release-contracts correctly skipped. Nothing failing; rust-tests and cloud were still pending.

Run release contracts when their CI job definition changes.

If a change edits only the release-contracts job in .github/workflows/ci.yml, this branch selects NORMAL. The release-input list does not include that workflow, so select does not add release-contracts. CI then skips the job whose invocation or permissions changed. Select release-contracts for this workflow, or detect changes to that job separately.

Not changing this. The release-contracts block in ci.yml only governs the CI-time call. Releases call release-contracts.yml directly from release.yml (line 45), and both of those files already select the job. So a bad edit to the ci.yml block cannot break a release. It would fail visibly on the next change that selects release-contracts, and actionlint in contracts still validates the block on every ci.yml change. Selecting on every ci.yml edit would add up to 23 release-contract runs a month (main touched ci.yml in 23 commits over the last 30 days), which is roughly the saving this PR exists for.

@nick-potts Thanks for the clarification. I withdraw this finding.

I treated the CI-time invocation as part of the release path. Releases call release-contracts.yml directly from release.yml, and changes to those files already select release-contracts. Keeping ci.yml changes on NORMAL preserves the intended savings while contracts still runs actionlint.

5Learning: In getployz/ployz, `.github/workflows/ci.yml` invokes `release-contracts` only for CI checks. Releases invoke `.github/workflows/release-contracts.yml` directly from `.github/workflows/release.yml`; changes to both release workflow files select release contracts. The selector in `scripts/ci.py` intentionally selects `NORMAL` for changes to `ci.yml` alone to avoid unnecessary release builds. The `contracts` job still runs actionlint on those changes. Do not require release-contract selection for every `ci.yml` edit solely because that workflow contains a CI-time invocation.

โœ… Review thread resolved.

You are interacting with an AI system.

Follow-up to the independent verification.

  • #1673 guard: fixed in ad0bd7c5c. ci.yml and cloud.yml set KACHE_S3_WRITES only when a main push has both write secrets and the bucket, and setup-rust fails a main push without it. Missing write keys can no longer pass by falling back to the read keys.
  • #1674 manifest gap: fixed in e65bf7660 (also the Codex P1).
  • #1674 argument length: fixed in e65bf7660. Release inputs are checked in batches of 1000 paths; a 40,000-path diff now selects in about 2 seconds.
  • Moving write keys into a main-only Environment stays a follow-up; it was already exposed before this change.

Independent verification (delta)

PASS at 315b305ae (e65bf7660 + merge of #1673). This closes both notes from my earlier review.

  • Any core/**/Cargo.toml or Cargo.lock change now selects release-contracts (scripts/ci.py:26-27). Checked with core/Cargo.toml and core/crates/ployz/Cargo.toml. dashboard/uptime/Cargo.toml correctly does not select it.
  • release_inputs_changed now sends paths in batches of 1000. A 40k-path diff no longer raises E2BIG, and a release input buried in that diff is still detected. An empty diff makes no call and returns false.
  • actionlint clean. test-ci.py OK. release-contracts is correctly skipped for this diff. CI still pending, no failures.

P2 Badge Treat Cargo configuration as a release input

When a PR adds or changes core/.cargo/config.toml, this predicate does not recognize it as a release input, so the new fallback selects NORMAL and skips release-contracts; target-specific linker or rustflag settings can therefore break the musl/ARM release builds while the PR gate remains green. Include Cargo configuration files alongside manifests in the release-input selection.

Valid. Fixed in fb3bb565d: any core/.cargo/ change now selects release-contracts, with a test case for core/.cargo/config.toml. No main commit touched core/.cargo in the last 30 days, so this costs no runs in practice.

  • Any core/.cargo/ path now selects release-contracts (scripts/ci.py:26-29). core/.cargo/config.toml selects all jobs.
  • The new test case catches the bug. With ci.py reverted to 315b305ae, test-ci.py fails on core/.cargo/config.toml (missing release-contracts). With the change, it passes.

P2 Badge Run release contracts when their caller workflow changes

When a change touches only .github/workflows/ci.yml, this branch returns NORMAL, even though that workflow defines the release-contracts call at lines 238โ€“245. A valid YAML change to its if, permissions, or secrets: inherit can therefore break or disable the reusable release job without exercising it on the resulting main push; for example, removing secret inheritance silently skips the required cache-write check until a later release-input change. Treat this caller workflow as a release input so the repository's PR gate validates the wiring it relies on.
