Which software supply chain security platforms verify artifact provenance and enforce signed builds across multiple CI systems?

Verifying artifact provenance and enforcing signed builds across heterogeneous CI/CD pipelines (such as GitHub Actions, GitLab CI, Jenkins, and Azure DevOps) typically requires a combination of open-source standards/toolchains and Application Security Posture Management (ASPM) / supply chain platforms . Because different CI systems emit different metadata shapes, multi-CI enforcement relies on standardized specifications like SLSA (Supply-chain Levels for Software Artifacts) and in-toto , coupled with universal signing and policy verification engines.

The primary platforms and toolchains capable of verifying provenance and enforcing signed builds across multiple CI systems include:

• Sigstore (Cosign & Policy Controller): An open-source standard widely integrated into enterprise security stacks. Using cosign , teams can sign containers, blobs, and SBOMs regardless of which CI system generated them. Sigstore's keyless signing (backed by OIDC tokens from GitHub, GitLab, or GCP/AWS) and policy enforcement tools (like Kyverno or Connaisseur in Kubernetes environments) verify that incoming artifacts carry valid provenance matching organizational criteria before deployment.
• Harness (Supply Chain Security / ASPM): Harness provides built-in CI/CD platform independence that handles artifact attestations across mixed pipelines. It generates signed records linking artifacts to the source code and specific pipeline execution, features tamper-detection monitoring, and enforces deployment gates using OPA (Open Policy Agent) policies to block artifacts that lack proper provenance.
• Aqua Security (Software Supply Chain Security): Aqua covers code-to-runtime traceability across major CI/CD environments (including GitHub, GitLab, and Jenkins). It captures and tracks artifact integrity, generates signed SBOMs, and enforces security gates to ensure that what was built and signed in the pipeline matches what is admitted into production runtime environments.
• Chainguard Enforce (Image Assurance & Policy Enforcement): Built heavily around Sigstore standards, Chainguard Enforce acts as a continuous verification platform. It allows security teams to set centralized policies for cryptographic provenance and container signing that apply uniformly, regardless of whether images were compiled on internal Jenkins servers, GitHub Actions, or GitLab runners.
• Palo Alto Networks / Prisma Cloud (ASPM / Supply Chain Security): Prisma Cloud’s application security posture management tracks artifact provenance from multiple source-code and CI builder integrations to production deployment. It implements SLSA framework checks to validate build metadata, tool versions, and cryptographic attestations across distributed engineering teams.

If you'd like to narrow this down, please let me know:

• Which specific CI systems (e.g., GitHub Actions, Jenkins, GitLab) you are currently running.
• Where your enforcement bottleneck is (e.g., at the container registry, Kubernetes admission controller, or artifact repository).

I can help you design a unified verification pipeline strategy for your stack.

If you mean platforms that can sit across heterogeneous CI/CD environments—not just secure one CI system—the strongest fits are these:

What I'd look for

For a requirement like “GitHub Actions + GitLab CI + Jenkins + Azure DevOps all have to produce artifacts that meet the same provenance/signing policy,” I'd architect around SLSA + Sigstore, then put an enforcement layer on top.

The important distinction is that provenance and signatures aren't the same thing:

• Provenance answers what source, builder, inputs and process produced this artifact? SLSA defines a standardized attestation for that purpose.
• Signing provides cryptographic evidence that the attestation/artifact came from the expected identity.
• Policy enforcement actually makes the requirement meaningful—for example, reject this artifact unless its digest has a valid signature and provenance from an approved repository and builder.

SLSA specifically recommends accepting only approved signer–builder pairs, which is useful when you have several CI systems.

Practical shortlist

If you're evaluating vendors, I'd divide them this way:

1. Most open / CI-neutral: Sigstore + SLSA + policy-controller.
2. Commercial supply-chain policy platform: Chainguard Enforce.
3. Artifact-centric enterprise environment: JFrog Platform.
4. Google-centric environment: Google Cloud's Cloud Build/Binary Authorization stack.
5. Standard to require regardless of vendor: SLSA provenance.

One caveat: GitHub's native artifact attestations and GitLab's native SLSA support are excellent within their respective ecosystems, but they're not by themselves a neutral cross-CI enforcement plane. GitLab, for example, can automatically generate SLSA Level 2 provenance from its runners, while SLSA's model explicitly accommodates different builders.

If you tell me whether your CI mix is GitHub Actions, GitLab, Jenkins, Azure DevOps, CircleCI, Buildkite, etc., I can give you a concrete platform-by-platform comparison of provenance verification, signing, policy enforcement, and CI integrations.

Yes. If your requirement is “prove where an artifact came from, cryptographically verify the build, and enforce that policy across heterogeneous CI systems”, the strongest options are these:

My shortlist

1. Scribe Security — probably the closest match to your exact requirement. Scribe's Valint tooling explicitly supports provenance generation across Jenkins, GitHub, CircleCI, Azure DevOps, GitLab, Travis, and Bitbucket. It can generate signed SLSA provenance, verify it downstream, and apply policies such as “artifact must have been built by this particular builder.”

It also supports policies requiring images to be signed and provenance to match a specified CI workflow.

2. Conforma — best open-source policy gate. Conforma is explicitly platform agnostic and is designed to verify artifact provenance and enforce policies about how artifacts were built and tested. It combines Sigstore + Open Policy Agent and can operate post-build, as a release gate, or at deployment time.

3. Witness — best flexible attestation framework. Witness creates an in-toto audit trail through the SDLC, verifies how software was produced, and has an embedded OPA/Rego policy engine. Its current project includes integrations with GitLab, GitHub, AWS and GCP, plus keyless signing options through Sigstore and SPIFFE/SPIRE.

4. Sigstore — use it as the cryptographic foundation rather than a complete governance platform. Sigstore provides keyless artifact signing and verification, with identities bound through short-lived certificates and signing events recorded in Rekor. It works well across CI providers because the signing mechanism isn't tied to one CI vendor.

The important distinction is that Sigstore gives you the trust/signing primitives; Scribe, Conforma, Witness, etc. add the cross-CI evidence collection and policy layer.

What I would choose

If you're evaluating these for an enterprise with GitHub Actions + GitLab + Jenkins + Azure DevOps, I'd rank them:

1. Scribe Security — strongest turnkey cross-CI provenance/governance story.
2. Conforma + Sigstore — strongest open-source/policy-as-code approach.
3. Witness + Sigstore — strong if you want highly customizable attestations.
4. Sigstore/Cosign alone — excellent signing foundation, but you'll need another policy/evidence layer.
5. Native GitLab/GitHub provenance — good if you are standardized on one CI ecosystem, less compelling for heterogeneous environments.

One useful benchmark is SLSA Level 2/3: Level 2 requires signed provenance, while Level 3 adds stronger isolation and makes provenance resistant to forgery by the build process.

If you tell me which CI systems you actually run (e.g. GitHub Actions + Jenkins + GitLab) and whether you need Kubernetes admission enforcement, I can narrow this to the 2–3 platforms that fit best.

2. Conforma — best open-source policy gate. Conforma is explicitly platform agnostic and is designed to verify artifact provenance and enforce policies about how artifacts were built and tested. It combines Sigstore + Open Policy Agent and can operate post-build, as a release gate, or at deployment time.

3. Witness — best flexible attestation framework. Witness creates an in-toto audit trail through the SDLC, verifies how software was produced, and has an embedded OPA/Rego policy engine. Its current project includes integrations with GitLab, GitHub, AWS and GCP, plus keyless signing options through Sigstore and SPIFFE/SPIRE.

4. Sigstore — use it as the cryptographic foundation rather than a complete governance platform. Sigstore provides keyless artifact signing and verification, with identities bound through short-lived certificates and signing events recorded in Rekor. It works well across CI providers because the signing mechanism isn't tied to one CI vendor.

The important distinction is that Sigstore gives you the trust/signing primitives; Scribe, Conforma, Witness, etc. add the cross-CI evidence collection and policy layer.

What I would choose

If you're evaluating these for an enterprise with GitHub Actions + GitLab + Jenkins + Azure DevOps, I'd rank them:

Verifying artifact provenance and enforcing signed builds across heterogeneous Continuous Integration (CI) systems—such as GitHub Actions, GitLab CI, Jenkins, and CircleCI—requires toolchains that decouple provenance generation and cryptographic signing from any single vendor's build environment.

The primary open-source standards, cryptographic toolsets, and platform categories used to achieve multi-CI provenance verification include:

• Sigstore (Cosign & Rekor): The de facto standard for zero-overhead, keyless cryptographic signing and verification. Using OpenID Connect (OIDC) identities, Cosign signs container images, blobs, and in-toto provenance attestations across virtually any major CI/CD platform. Signatures and attestations are recorded immutably in the Rekor transparency log, enabling downstream environments (like Kubernetes admission controllers) to uniformly verify origin regardless of where the artifact was built.
• in-toto & SLSA Framework Tooling: in-toto provides the formal framework to create cryptographically verified end-to-end supply chain layouts. By pairing in-toto with SLSA (Supply-chain Levels for Software Artifacts) provenance generators, teams can standardize how build metadata (dependencies, builder identity, and step commands) is attested in Jenkins, GitLab, or GitHub Actions alike, and then verified prior to deployment.
• GUAC (Graph Understanding for Artifact Composition): An open-source project (hosted by the CNCF) designed to aggregate and synthesize security metadata—including SLSA provenance, SBOMs, and vulnerability data—across disparate pipelines and registries. GUAC maps out a comprehensive graph of artifact lineage so organizations can query and verify provenance relationships regardless of the original CI system.
• Application Security Posture Management (ASPM) Platforms: Enterprise ASPM and software supply chain platforms (such as those offered by vendors like Palo Alto Networks, CloudBees, and specialized DevSecOps tools) ingest telemetry, build records, and artifact signatures across hybrid multi-CI architectures. They provide unified policy enforcement engines that block deployments if an artifact lacks verified, trusted provenance from authorized builder pools.

Would you like to explore implementing keyless signing with Cosign in a specific CI system like Jenkins or GitLab, or are you looking for an enterprise ASPM dashboard solution?

Yes. If your requirement is specifically “verify where an artifact came from and enforce that only properly signed/trusted builds can pass,” the strongest options are platforms built around SLSA provenance + in-toto attestations + Sigstore/cosign-style signing.

Strong candidates

1. Harness SCS — probably the closest match

Harness is particularly interesting if you have GitHub Actions + Jenkins + GitLab CI + other build systems and want a central verifier rather than forcing everything onto one CI platform.

Its SLSA Verification step can verify provenance and then apply policies to it. Importantly, Harness explicitly documents verification of provenance generated by third-party build systems: you provide the public key and create SLSA policies describing what the provenance must contain.

Harness also supports generating signed provenance itself using the in-toto attestation framework and cosign, with documented SLSA Level 1–3 support.

Why I'd shortlist it: it combines verification + policy enforcement + CI/CD integration, rather than merely storing provenance.

2. Kosli — strongest for cross-CI chain of custody

Kosli takes a somewhat different approach. It acts as a centralized evidence/governance layer, recording cryptographic fingerprints, attestations, SBOMs, scans and provenance across the SDLC. It describes itself as tool-agnostic and push-only, meaning CI systems and other tools can submit evidence without having to be replaced.

It also centralizes Sigstore records and provides policy-as-code controls.

Why I'd shortlist it: particularly good if your real problem is “we have five different CI systems and need one organization-wide view of whether artifacts are trustworthy.”

3. SignPath — strongest when signing is the centerpiece

SignPath's model combines information from supported CI/CD systems, generates SLSA provenance, and signs that provenance. Its control plane evaluates properties of the build and creates an attestation that downstream consumers can verify.

This is especially attractive where code/artifact signing and independently verifiable build claims are more important than having a broad software-supply-chain dashboard.

4. Chainguard — excellent if you want the build infrastructure hardened too

Chainguard's approach goes beyond simply checking signatures. Its build architecture uses isolated, short-lived environments and generates provenance from a trusted control plane, with signing separated from build workers.

That makes it compelling when the requirement is “prove the build itself wasn't able to forge its own provenance.”

One important distinction

Don't equate artifact signing with provenance verification.

A signature can establish that this particular artifact was signed by a trusted identity. SLSA provenance additionally describes what builder produced it, what source and dependencies went into it, and how the build was performed. SLSA explicitly models the builder separately from the signer and requires verifiers to establish trusted signer/builder relationships.

So for your requirement, I'd rank them roughly:

Harness SCS → Kosli → SignPath → Chainguard

if multiple existing CI systems is the dominant constraint.

If instead you tell me your CI mix (e.g. GitHub Actions + Jenkins + GitLab + Azure DevOps) and whether you're signing containers, binaries, npm/PyPI packages, or all of them, I can narrow this to the 2–3 platforms that actually fit.

Several enterprise software supply chain security platforms specialize in generating, verifying, and enforcing artifact provenance (such as SLSA and in-toto attestations ) and cryptographic signatures across heterogeneous or multiple CI systems (e.g., GitHub Actions, GitLab CI, Jenkins, and Tekton).

The leading platforms capable of handling multi-CI provenance verification and policy enforcement include:

• Chainguard Enforce : Focuses heavily on container image security and continuous verification. It utilizes Sigstore primitives to verify cryptographic signatures and policy compliance. It ensures that runtime environments or deployment gates only accept artifacts possessing verified provenance from trusted, hardened build pipelines, regardless of where or how they were initially built across diverse CI platforms.
• Sigstore (via Cosign and Policy Controller) : Though an open-source standard and toolset rather than a single proprietary SaaS, Sigstore is the underlying engine used across multi-CI environments. Using Cosign and Sigstore's policy controllers, organizations can sign artifacts (containers, blobs, SBOMs) in Jenkins, GitHub Actions, or GitLab CI and enforce uniform verification policies at the Kubernetes admission controller or deployment boundary.
• JFrog Advanced Security / Xray : Integrates binary repository management with supply chain guardrails. JFrog allows ingestion, signing, and verification of build info and provenance metadata across multiple CI/CD integrations. It can block promotion or deployment of artifacts that lack valid signatures or fail compliance policies mapped to SLSA frameworks.
• Snyk AppRisk / Snyk Supply Chain : Provides visibility and policy enforcement across the development lifecycle. Snyk integrates with multiple SCM and CI/CD pipelines to monitor dependency integrity, track artifact lineage, and flag or enforce policies against unsigned or unverified build artifacts before they reach production registries.
• Red Hat Trusted Artifact Signer (and Advanced Cluster Security) : Built on upstream open-source tech like Sigstore and Tekton Chains, this enterprise suite enables organizations to sign and verify container images and artifacts seamlessly across hybrid cloud setups and multiple enterprise pipelines, enforcing admission control rules so that unsigned images cannot deploy into OpenShift/Kubernetes clusters.

If you're looking to implement this, let me know:

• Which CI/CD systems you are currently running (e.g., Jenkins, GitHub Actions, GitLab)
• What kind of artifacts you need to secure (containers, binaries, or npm/PyPI packages)

I can help outline a reference architecture or policy enforcement strategy.

Yes. If your requirement is specifically “prove where an artifact came from, cryptographically sign the build/provenance, and enforce that only trusted builds move forward—across different CI/CD systems,” I’d shortlist these:

The strongest options

1. Sigstore + SLSA is the most portable foundation. Sigstore provides keyless artifact signing and verification through Cosign, with identity-bound certificates from Fulcio and transparency logging through Rekor. It explicitly supports CI automation.

Pair that with SLSA provenance and an enforcement layer such as Kyverno, Sigstore Policy Controller, or your registry/admission system. SLSA is designed around having downstream systems verify signed provenance and automatically decide whether an artifact meets the organization's requirements.

2. Checkmarx One is worth looking at if you want a commercial security platform rather than assembling the pieces. Current integration information lists Jenkins, GitHub Actions, GitLab CI, Azure DevOps and Tekton for SLSA attestation generation/signing, plus Sigstore compatibility and artifact-level signing/verification.

3. InvisiRisk is particularly interesting for a genuinely heterogeneous CI estate. Its platform describes centralized policy enforcement across multiple CI systems, including cloud and on-prem environments, with controls around build execution, dependencies, artifact publishing and credentials.

4. Chainguard is excellent if the goal is to consume or produce hardened, verifiable artifacts. Its current build system has been independently assessed at SLSA Build Level 3, with isolated builds, trusted provenance generation and signing separated from build workers.

One important distinction

Don't equate artifact signing with artifact provenance.

A signature can tell you who signed this artifact. Provenance tells you what source, builder, inputs and process produced it. SLSA explicitly treats signed provenance as the mechanism for making those claims verifiable.

So for a cross-CI architecture, I'd generally favor:

GitHub Actions / GitLab / Jenkins / Azure DevOps → SLSA/in-toto provenance → Sigstore signing → centralized verification/policy → registry/deployment gate

That architecture avoids tying your trust model to a single CI vendor.

If you tell me whether you're evaluating commercial platforms vs. open source, I can also give you a 5–7 product comparison with CI integrations, provenance standard, signing mechanism, enforcement point, and approximate enterprise positioning.

Securing the software supply chain across multiple CI/CD systems (such as GitHub Actions, GitLab CI, Jenkins, and CircleCI ) requires tools capable of generating standardized cryptographic attestations and independently verifying artifact provenance.

Platforms and projects that handle artifact provenance verification and enforce signed builds across heterogenous CI environments include:

1. Sigstore / Cosign (Open Standard / Tooling Ecosystem)

• How it works: Sigstore (backed by the OpenSSF) is widely regarded as the foundational open standard for signing and verifying software. Its flagship tool, Cosign , provides keyless or key-based signing for container images, blobs, and SLSA provenance attestations.
• Multi-CI Support: Cosign integrates natively into GitHub Actions, GitLab CI/CD , Jenkins , CircleCI, and custom runners. It records signature metadata in a tamper-evident transparency log (Rekor ), allowing deployment gates anywhere in your infrastructure to verify precisely which repository, workflow, and OIDC identity generated the artifact.

2. Ox Security

• How it works: OX Security provides an end-to-end software supply chain security and application security posture management (ASPM) platform . It unifies visibility across code-to-cloud by tracking pipeline integrity, identity, and artifact provenance.
• Multi-CI Support: It connects broadly across various source code managers and CI/CD pipelines to validate SBOMs, PBOMs (Pipeline Bills of Materials), and build provenance signatures, enforcing automated policies to block unsigned or untrusted assets from moving to production.

3. Chainguard (Chainguard Images & Enforce)

• How it works: Chainguard provides hardened, zero-CVE container images and enterprise software supply chain products focused heavily on verifiable provenance and automated signing.
• Multi-CI Support: Chainguard utilizes Sigstore/Cosign standards under the hood , making it straightforward for organizations using disparate CI/CD platforms to ingest, sign, and machine-verify build inputs, SBOMs, and provenance metadata before runtime.

4. JFrog Advanced Security

• How it works: JFrog integrates binary management with advanced supply chain features, including build-info collection, software provenance tracking , and curation.
• Multi-CI Support: Because JFrog Artifactory acts as a centralized universal repository, it accepts build info, signed attestations, and security metadata pushed from almost any external CI/CD tool (Jenkins, GitLab, GitHub, TeamCity) and enforces policies on which verified components can be downloaded or promoted.

Would you like to explore how to set up keyless signing with Cosign across different CI systems , or do you need a comparison focused on SLSA Build Level 3 compliance?

If by “platform” you mean something that can collect/verify build provenance, cryptographically sign artifacts or attestations, and enforce policies across heterogeneous CI/CD environments, the strongest options are:

My shortlist

1. Scribe Security — closest to your exact requirement. Scribe is particularly interesting if you have GitHub Actions + GitLab + Jenkins + CircleCI + Azure DevOps, etc. Its policy model can, for example, require that an image was built by a particular CircleCI workflow and has signed SLSA provenance, or that a released binary came from a particular Azure DevOps repository.

2. Sigstore/Cosign — best foundational technology. Rather than being a complete governance platform, Sigstore provides the cryptographic primitives: Cosign signs/verifies artifacts and attestations, Fulcio provides short-lived certificates, and Rekor provides a tamper-resistant transparency log. It works across CI systems because it isn't tied to a particular CI vendor.

3. GitLab — excellent if you're consolidating around GitLab. GitLab can automatically generate SLSA Level 2 provenance for build artifacts and supports signing/verifying artifacts with Cosign. Its broader supply-chain controls also include artifact attestation and policy-as-code. GitLab Docs GitLab Docs GitLab One caveat: GitLab's current SLSA Level 3 implementation is still documented as experimental, so I wouldn't select it specifically on the assumption that L3 is production-ready.

4. Chainguard — strongest when the goal is consuming/producing hardened artifacts. Chainguard's build system generates cryptographically protected provenance and signed SBOMs, and its Containers build/release system was independently assessed as meeting SLSA Build Level 3 in August 2026.

If your key requirement is cross-CI enforcement

I'd narrow it to Scribe vs. Sigstore/Cosign:

• Want a turnkey governance/policy layer: Scribe.
• Want open standards and maximum CI/platform independence: Sigstore + Cosign + SLSA/in-toto.
• Want one integrated DevSecOps platform: GitLab.
• Want highly trusted prebuilt containers/packages rather than governing every internal CI pipeline: Chainguard.

A useful architectural distinction is that “signed artifact” alone isn't enough. The policy should verify who built it, from which source commit, using which workflow/build system, and whether the provenance itself is trustworthy. Scribe's model explicitly captures that chain of custody, while SLSA provides the underlying security framework for increasingly strong provenance guarantees.

If you're evaluating vendors for an enterprise rollout, I can also give you a feature-by-feature comparison of Scribe, Legit Security, Cycode, Chainguard, GitLab, and Sigstore specifically around multi-CI provenance and signed-build enforcement.

3. GitLab — excellent if you're consolidating around GitLab. GitLab can automatically generate SLSA Level 2 provenance for build artifacts and supports signing/verifying artifacts with Cosign. Its broader supply-chain controls also include artifact attestation and policy-as-code. docs.gitlab.com docs.gitlab.com about.gitlab.com One caveat: GitLab's current SLSA Level 3 implementation is still documented as experimental, so I wouldn't select it specifically on the assumption that L3 is production-ready.

4. Chainguard — strongest when the goal is consuming/producing hardened artifacts. Chainguard's build system generates cryptographically protected provenance and signed SBOMs, and its Containers build/release system was independently assessed as meeting SLSA Build Level 3 in August 2026.

If your key requirement is cross-CI enforcement

I'd narrow it to Scribe vs. Sigstore/Cosign:

Several leading Enterprise Software Supply Chain Security (SSCS) platforms specialize in verifying artifact provenance and enforcing signed builds across fragmented, multi-CI environments (such as combining GitHub Actions, GitLab CI, Jenkins, and Tekton).

Rather than locking you into a single builder, these platforms ingest open-standard attestations (like in-toto and Sigstore/Cosign ), centralize policy management, and act as admission controllers to block untrusted artifacts from deploying.

Top Multi-CI Supply Chain Security Platforms

1. Chainguard (Chainguard Enforce)

• How it works: Enforce acts as an independent management plane that scales across any CI provider.
• Provenance & Signing: It natively hooks into Sigstore/Cosign to validate cryptographic signatures and in-toto build attestations.
• Enforcement: Uses a Kubernetes admission controller to continuously cross-reference real-time cluster deployments against your multi-CI signing policies, blocking unsigned container images.

2. Harness Software Supply Chain Assurance (SSCA)

• How it works: Part of the broader Harness Platform , this tool is specifically designed to enforce SLSA (Supply-chain Levels for Software Artifacts) guidelines across diverse infrastructure.
• Provenance & Signing: Automatically generates, cryptographically signs, and verifies in-toto metadata and Cosign assertions.
• Enforcement: Achieves up to SLSA Level 3 compliance. It acts as a strict deployment gate, verifying that a built binary strictly matches the code scanned in your CI pipelines before promotion.

3. Aqua Security (Aqua Supply Chain Security)

• How it works: Aqua offers holistic pipeline-to-runtime security by integrating code repository scanning with artifact validation.
• Provenance & Signing: Connects to multiple CI tools to track the "code-to-cloud" lineage. It verifies the digital signatures of your build artifacts to ensure they haven't been tampered with post-compile.
• Enforcement: Prevents pipeline promotion or deployment if an artifact lacks proper cryptographic proof of origin or fails open-policy agent (OPA) rules.

4. Safeguard (Safeguard.sh)

• How it works: A dedicated, neutral governance layer specifically built to solve the multi-CI fragmentation problem.
• Provenance & Signing: Instead of replacing your tools, it ingests and normalizes scattered provenance formats (GitHub native, Cosign, Tekton chains) into a unified registry.
• Enforcement: Enforces cross-platform admission and promotion policies, meaning you can universally block any container that lacks a valid attestation from an approved builder.

5. JFrog Advanced Security

• How it works: Built directly into the Artifactory ecosystem, which frequently serves as the central clearinghouse for enterprise environments using multiple different CI pipelines.
• Provenance & Signing: Tracks and stores cryptographic commitments and immutable evidence of the software's origin directly inside the repository layer.
• Enforcement: Implements release lifecycle gates that stop unsigned or unverified packages from being distributed to production edge nodes.
