ci: auto-merge Dependabot PRs that pass all required checks#614
Merged
Conversation
Adds a workflow that enables GitHub's native auto-merge (squash) on Dependabot's own PRs. The actual merge is gated by the branch's required status checks (lint, build, e2e, audit) — auto-merge waits for them, so a bump only lands when the full CI suite is green. No approval step is needed (main requires 0 reviews). Applies to all update types, including majors, as long as CI passes; a commented note shows how to exclude majors later.

Adds a dependabot/fetch-metadata step and gates auto-merge on update-type != semver-major. Patch and minor bumps auto-merge once the required checks pass; major bumps stay open for manual review. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Enables GitHub's native auto-merge (squash) on Dependabot's own PRs for patch and minor bumps. A new workflow (
dependabot-automerge.yml) turns on auto-merge; GitHub then merges only once the branch's required status checks pass — so a bump lands only when the full suite is green. Major bumps are left open for manual review (gated viadependabot/fetch-metadataonupdate-type != semver-major).Companion change (already applied to
mainbranch protection): required status checks expanded from justbuildtolint+build+e2e+audit. Without this, auto-merge would fire onbuildalone. CodeQL is intentionally left non-required (it legitimately "skips" on some docker/actions-only PRs, which would otherwise stall merges).allow_update_branchis on, so auto-merge auto-updates a behind PR branch under thestrict(up-to-date) rule.No approval step —
mainrequires 0 reviews.Consequences:
main→deploy.yml→flyctl deploy, so passing non-major bumps ship to production automatically.Note: this PR is not itself a Dependabot PR, so it won't auto-merge — merged manually once green.
