[Feature Request] Integration of deterministic security gates for CI/CD hardening

[DataWizual-Labs]

As Dagster handles mission-critical data workflows, any compromise in the CI/CD pipeline or an accidental secret exposure in infrastructure-as-code can be devastating. Traditional security scanners are often passive and can be bypassed, leading to risks of secret exposure in logs and supply-chain attacks via unpinned GitHub Actions.

I have developed a tool called Sentinel Core. It is a deterministic gatekeeper designed to enforce hard security invariants directly in the pipeline. It blocks non-compliant commits before they can reach your environments.

Proposed Implementation & Architecture
The system follows an Administrative Provisioning model to ensure the security gate remains tamper-proof and strictly follows organization policies:

Administrative Provisioning: The runner/worker is provisioned exclusively via a protected start.sh script by a Security Administrator. This binds the engine to the infrastructure and ensures a hardened environment.

Offline Enforcement: The engine operates with Zero Telemetry, ensuring that sensitive configurations and credentials never leave the authorized admin perimeter.

Deterministic Invariants: Sentinel evaluates Dockerfiles, CI/CD workflows, and IaC (Kubernetes/Terraform) at the artifact level. It enforces mandatory SHA-pinning and blocks unsafe deployment posture by issuing a binary ALLOW (0) or BLOCK (1) decision.

Immutable Governance: Policies are managed in a separate "Shield" repository. This prevents developers from overriding security rules within the local project repository.

I would like to discuss how these automated guards can be integrated into your development lifecycle to eliminate human error and harden the project's delivery pipeline.
