feat(security): git-steer owns remediation — disable Dependabot auto-fixes - #87
Merged
Conversation
…fixes ADR-007 single-channel policy. The heartbeat enabled Dependabot's automated-security-fixes on every managed repo, which made Dependabot open its OWN ungated security PRs for the same CVEs git-steer remediates through the gated, per-package worker — two systems patching the same vulnerabilities, one verified and one not. The enforce step now keeps vulnerability ALERTS enabled (git-steer's OBSERVE source) but DISABLES automated-security-fixes (DELETE), so the gated worker is the sole remediation channel. Routine non-security version updates (dependabot.yml) are unaffected. Already applied to DriveIQ; the redundant Dependabot security PRs were closed.
