Summary

Last month's Dependabot PR for the EQL workspace (#1205) broke CI for the whole repository. EQL is the SQL library this repo installs into customers' Postgres databases; it has its own Cargo workspace under packages/eql. To bump two crates there, Dependabot rewrote the root workspace's Cargo.toml, but didn't update the root Cargo.lock or the Go guest that pins the same crate. Every root --locked build and the Go guest job then failed.

This PR stops the EQL Dependabot entry from ever editing a manifest, makes it ignore the crates the root workspace moves by hand, and adds a test so the two Dependabot entries can't drift apart again.

Changes

  • .github/dependabot.yml, the /packages/eql cargo entry:

    • versioning-strategy: lockfile-only: the entry can no longer edit any Cargo.toml, the root one included. An update that would need a manifest change is dropped rather than proposed.
    • New ignores: recipher, cllw-ore, zerokms-protocol and vitaminc*. These are the root entry's hand-moved crates that the EQL lockfile also resolves. cts-common was already ignored.
    • The comments explain why: tests/encryption depends by path on stack-kms and stack-encrypt, and eql-bindings on stack-encrypt. Those crates declare these dependencies { workspace = true }, so the requirements come from the root Cargo.toml. I also fixed the stale "five members" count in the entry's header, which is six now, tests/encryption included.
  • New scripts/__tests__/dependabot-eql-inherited-ignores.test.mjs, which fails when:

    • the EQL entry stops being lockfile-only;
    • the root cargo entry ignores a crate the EQL entry doesn't, unless an exemption with a reason covers it;
    • an exemption is stale;
    • the EQL workspace no longer depends by path on any root-workspace crate, so the file has to be retired rather than passing with nothing to check.

    It reads the path dependencies from the tracked EQL manifests, so a new one is covered automatically.

Verification

  • The new test failed on main, listing the four missing crates. With the change, 5 of 5 pass.
  • Each check fails when its condition is broken:
    • removing versioning-strategy fails the lockfile-only test;
    • removing the cllw-ore ignore fails the comparison, naming cllw-ore;
    • adding a fake exemption fails the stale-exemption test.
  • pnpm exec vitest run --config scripts/vitest.config.mjs: 76 files, 1357 tests pass.
  • e2e/tests/supply-chain.e2e.test.ts, which also reads dependabot.yml: 29 of 29 pass.
  • pnpm run code:check: 0 errors.
  • Not verifiable before merge: how Dependabot behaves under lockfile-only. The next monthly EQL run will show it.

Review notes

Summary by CodeRabbit

  • Chores
    • Restricted Cargo update proposals for the root workspace, EQL workspace, and protect-ffi to lockfile-only changes.
    • Expanded EQL workspace coverage and adjusted ignored crates.
    • Broadened the accepted prettyplease version range.
  • Tests
    • Added checks for Cargo update settings, workspace coverage, and consistency of ignored crates and cross-workspace path dependencies.

The EQL workspace depends by path on root-workspace crates: tests/encryption
on stack-kms and stack-encrypt, eql-bindings on stack-encrypt. Those crates
declare recipher, cllw-ore and vitaminc as `{ workspace = true }`, so their
requirements come from the ROOT Cargo.toml even inside the EQL workspace.
The /packages/eql Dependabot entry ignored none of them, so its monthly PR
(#1205) bumped them in the EQL lock and, to satisfy the root's exact pins,
rewrote the root Cargo.toml without updating the root Cargo.lock or the Go
guest's recipher pin. Every root `--locked` build and the guest failed.

The entry is now `versioning-strategy: lockfile-only`, so it cannot edit
any manifest, and it ignores the crates the root entry moves by hand
(recipher, cllw-ore, zerokms-protocol, vitaminc*), so its lockfile does not
move them apart from the root's.

scripts/__tests__/dependabot-eql-inherited-ignores.test.mjs fails when the
entry stops being lockfile-only, when the root entry ignores a crate it
does not, or on a stale exemption. It derives the path dependencies from
the tracked EQL manifests, and fails if they disappear rather than passing
vacuously.

Closes #1207

📝 Walkthrough

Cargo Dependabot settings now use lockfile-only updates in the root, protect-ffi, and EQL entries. The EQL entry adds a workspace member and inherited dependency ignores. New script tests check cross-workspace update settings and EQL ignore alignment. EQL codegen broadens its prettyplease version requirement.

Changes: Cargo Dependabot policy

Layer / File(s) Summary
Lockfile-only workspace updates
.github/dependabot.yml
The root, protect-ffi, and EQL Cargo entries use lockfile-only. The EQL workspace description adds tests/encryption.
EQL inherited dependency ignores
.github/dependabot.yml, scripts/__tests__/dependabot-eql-inherited-ignores.test.mjs
The EQL entry adds ignores for recipher, cllw-ore, zerokms-protocol, and vitaminc*. The test checks inherited ignore coverage, EQL path dependencies into the root workspace, and exemption validity.
Cross-workspace update checks
scripts/__tests__/dependabot-cargo-cross-workspace.test.mjs
The test discovers cross-workspace path dependencies and checks that destination crates have a covering Cargo entry and that entries covering either endpoint use lockfile-only.

Explanation

The whole-PR changes include packages/eql/crates/eql-codegen/Cargo.toml, which changes prettyplease from =0.2.37 to 0.2. This dependency change has no demonstrated connection to #1207 or to the Dependabot drift tests. The generalized lockfile-only checks for cross-workspace Cargo entries are connected to the same cross-workspace failure mode.

Review attestation: automated /code-review medium + /cross-check-review-findings on b1ab8c8.

Result: no critical or blocking findings.

Checked by reading the diff against the repo (the new test was not run, see the last bullet):

  • Ignore list matches the root entry. The root cargo entry (.github/dependabot.yml:236-276) ignores cts-common, zerokms-protocol, recipher, cllw-ore and vitaminc*. The EQL entry already ignored cts-common; this PR adds the other four, so the two lists now agree.
  • Manifest edits are blocked. versioning-strategy: lockfile-only is a valid option for the cargo ecosystem and stops the EQL entry from editing the root Cargo.toml, which caused the #1205 and #1207 breakage.
  • The test's inputs resolve.
    • js-yaml is a root devDependency, and scripts/__tests__/lib/repo-root.mjs exists.
    • The members regex matches the root Cargo.toml layout.
    • The path-dependency scan finds stack-encrypt and stack-kms from tests/encryption and eql-bindings. The vacuity guard is therefore not trivially green.
    • Ignore rules that carry update-types (the semver-major rule) are correctly not counted as ignores.
  • No changeset needed. The change is CI and tooling only, with no published package or skills/ impact. AGENTS.md already lists tests/encryption as an EQL workspace member, so there is no meta-file drift.
  • Not verified here. node_modules is not installed in this run, so the new test was not executed. Please rely on CI for that.

Nit, non-blocking: the rewritten comment line at .github/dependabot.yml:142-143 (tests/encryption) and its own Cargo.lock. It needs its own entry because Dependabot's cargo) runs well past the wrapping of the lines around it.

Review of b1ab8c8. No blocking defects.

Checks. All checks pass. I ran the tests again in a worktree at this head:

  • scripts/vitest.config.mjs: 76 files, 1357 tests pass. The new file gives 5 of 5.
  • e2e/tests/supply-chain.e2e.test.ts: 29 of 29 pass.
  • The other repo tests that read .github/dependabot.yml (scripts/__tests__/impact-workflow.test.mjs, scripts/__tests__/musl-build-image.test.mjs) also pass.

Correctness:

  • Rationale. The rationale is correct. #1205 changed only the root Cargo.toml (+2 -2) and packages/eql/Cargo.lock.
  • lockfile-only is valid for cargo. The GitHub Dependabot options reference lists cargo as an ecosystem that supports versioning-strategy.
  • Directories and ecosystems do not change. No manifest loses its entry.
  • The new ignores have an effect. packages/eql/Cargo.lock resolves recipher 0.3.1, cllw-ore 0.5.0, zerokms-protocol and vitaminc 0.5.1 through stack-encrypt and stack-kms, so each new ignore stops a real update.

Suggested follow-up PR:

  1. Write the security-update effect in the comment. The options reference marks versioning-strategy as an option for both version updates and security updates. Thus, after this PR, the EQL entry also drops a security fix that needs a manifest edit. The new comment at .github/dependabot.yml:153-158 does not say this. The earlier text at :163-165 ("Security fixes are unaffected") can now cause confusion. Give the same caveat that the ignore block gives at :193-195, and refer to osv-scanner.
  2. prettyplease loses its Dependabot updates. packages/eql/crates/eql-codegen/Cargo.toml:16 pins prettyplease = "=0.2.37". With lockfile-only, Dependabot cannot propose any change to it. If the pin is intentional (stable codegen output), write that in the manifest. If not, change it to a caret requirement.
  3. The protect-ffi entry has the same risk, one level down. languages/typescript/packages/protect-ffi/crates/protect-ffi/Cargo.toml:37 depends by path on eql-bindings, which is in the EQL workspace. The protect-ffi cargo entry (.github/dependabot.yml:62-137) does not use lockfile-only. Thus a protect-ffi Dependabot PR can edit packages/eql/crates/eql-bindings/Cargo.toml without a change to packages/eql/Cargo.lock. The risk is small today, because eql-bindings uses plain caret requirements and protect-ffi does not enable the stack-encrypt feature. But the new test examines only the EQL-to-root edge. Think about making the test general: every cargo entry with a path dependency outside its own workspace must be lockfile-only.

The EXEMPT reason check (CodeRabbit) and the line-wrap nit at :142-143 (earlier review) are still open. I do not repeat them.

…path edges

Addresses the review on this PR.

- Generalise the lockfile-only guard. A new test reads every path
  dependency across the cargo Dependabot workspaces and requires
  `versioning-strategy: lockfile-only` on each entry at either end of
  one. That covers protect-ffi (path dep on eql-bindings) and the root
  entry (the fuzz crates and Go guests depend on root crates, and EQL
  depends on stack-encrypt/stack-kms), both the #1205 shape one edge
  over. Both entries are now lockfile-only.
- State in each lockfile-only comment that it also drops a security
  update needing a manifest edit, and that osv-scanner still reports it;
  reword the "Security fixes are unaffected" line.
- Count an EXEMPT entry only when its reason is non-blank.
- Rewrap the long EQL entry comment.
- Relax eql-codegen's `prettyplease = "=0.2.37"` pin to "0.2": nothing
  records a reason for it, rustfmt formats the output last, and under
  lockfile-only Dependabot could never move an exact pin. Cargo.lock is
  unchanged.

47-61: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Regex-based members parsing can pick up the wrong array.

The pattern ^members\s*=\s*\[([\s\S]*?)\] matches the first line-start members = anywhere in the manifest, and stops at the first ]. A member path containing ] is unlikely. A commented or nested key is also unlikely. The tests assert only that glob members are absent. If a workspace uses exclude or a different layout, the discovered edges can silently shrink. The test at Line 126 guards only against zero edges. The current manifests parse correctly, so this is a low-risk fragility. A TOML parser would remove it.
