Summary

  • constrain Renovate-managed Go toolchain updates to the 1.26 release line (>=1.26.0 <1.27.0)
  • keep prek hook repositories discoverable after the prek.toml migration, including four-component tags
  • keep major dependency updates manual by applying the no-automerge rule last

Validation

  • renovate-config-validator 44.168.4
  • Renovate 44.168.4 local dry-run dependency extraction
  • semver range check: only 1.26.9 accepted from 1.25.8, 1.26.9, and 1.27.2

Summary by CodeRabbit

  • Chores
    • Refined automated dependency updates for repository and Go version references, including version limits and merge settings. These changes affect maintenance workflows and do not add user-facing features.

📝 Walkthrough

The Renovate configuration replaces the built-in pre-commit manager with a regex custom manager for dependencies in prek.toml. It adds a version range and disables automerge for matching golang/go updates in mise.toml.

Changes: Renovate dependency rules

Layer / File(s) Summary
prek dependency extraction and automerge
renovate.json
A regex custom manager extracts GitHub repositories and revisions from prek.toml using GitHub tags. Matching dependencies automerge at priority 4.
Go toolchain version policy
renovate.json
A rule limits matching golang/go GitHub-tag dependencies in mise.toml to versions from 1.26.0 up to, but not including, 1.27.0 and disables automerge. The Go module rule retains automerge at priority 3, and the major-update rule retains disabled automerge and priority -1.

Priority: ⬇️ Low

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

Change: Other

Merge Risk: ⚪ Minimal · up to 15bb2

Renovate can discover the prek hooks, keeps major hook updates manual, and limits mise Go updates to 1.26.x without automerging. No concrete merge-blocking risk remains.

Security architecture risk: 🔵 Low · up to 15bb2

The changes are limited to dependency-update automation. Major updates are configured to remain manual, and Go toolchain updates are restricted to 1.26.x without automatic merging. No concrete security regression was established, but the hook-update path relies on external tag publishers and merge controls whose deployed enforcement was not verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The newly automated supply-chain path affects this repository’s hook revisions and environments that execute those hooks. The evidence does not establish those environments’ credentials, sandboxing, or any downstream production reach.

Security Findings and Attack Paths

  • inferred — A malicious eligible release from a configured upstream hook repository could flow through automatic revision updates into later hook execution. This requires control of a selected upstream release source, or a repository change selecting another source; the inspected configuration does not establish an arbitrary unauthenticated input path or a demonstrated policy bypass.

Trust Boundaries and Controls

  • observed — Automatic-update authority is scoped by manager and filename, with automerge disabled globally unless a rule enables it. The final major-update rule and explicit Go manual-update rule constrain that authority. These are configured controls, not proof of deployed branch-protection enforcement.
