Compatibility

What CI/lock is built for, tested against, and known to interoperate with.

Sources: rookery/cilock/go.mod, rookery/.github/workflows/release.yml, rookery/cilock/cmd/cilock/main.go.

Toolchain

	Version
Go (build)	1.26.0+ (per go.mod)
Build flags	CGO_ENABLED=0, GOWORK=off, -trimpath
FIPS mode	On by default (//go:debug fips140=on in main.go)

Released platforms

The official rookery release pipeline produces static binaries for:

OS	Architectures	Notes
Linux	amd64, arm64	Full feature set including --trace (ptrace)
macOS (Darwin)	amd64, arm64	All attestors except --trace (ptrace is Linux-only)
Windows	(not shipped)	Not shipped: the omnitrail attestor has linux/darwin-only build constraints (per release.yml comment).

To build a Windows binary anyway, fork cilock/cmd/cilock/main.go and remove the omnitrail import.

Container image

Registry	ghcr.io/aflock-ai/cilock
Tags	<version> (current: v1.1.0) and latest
Built with	Chainguard melange + apko
Architectures	x86_64, aarch64
Signed by	cosign (keyless OIDC)

CI platforms

Tested integrations from the cilock-action ecosystem:

Platform	Integration	Source
GitHub Actions	aflock-ai/[email protected] (also @v1)	cilock-action
GitLab CI	Reusable template at cilock-action/gitlab/cilock.gitlab-ci.yml	Same repo
Jenkins	Via the jenkins attestor + raw cilock binary	rookery/plugins/attestors/jenkins
AWS CodeBuild	Via the aws-codebuild attestor	rookery/plugins/attestors/aws-codebuild

Signers

The default cilock binary blank-imports two signer providers — file and fulcio (verified from cilock/cmd/cilock/main.go):

Signer	Module	In default binary?
Sigstore Fulcio	plugins/signers/fulcio	✅ default
File (PEM)	plugins/signers/file	✅ default
KMS (--signer-kms-ref: awskms://, gcpkms://, azurekms://, hashivault://)	plugins/signers/kms/{aws,gcp,azure}	⚙️ flag present, provider opt-in
debug-signer	plugins/signers/debug-signer	builder opt-in
SPIFFE/SPIRE	plugins/signers/spiffe	builder opt-in
HashiCorp Vault	plugins/signers/vault, vault-transit	builder opt-in

The --signer-kms-ref flag is present in the default binary, but no KMS provider is compiled in — passing it errors with no kms provider found until you build a variant that imports plugins/signers/kms/{aws,gcp,azure}. The other "builder opt-in" signers likewise exist as Go modules in rookery but aren't blank-imported by default. Add the import to cilock/cmd/cilock/main.go (or use rookery-builder --with …) and rebuild — see build a custom CI/lock.

Timestamp authorities

RFC 3161 compatible TSAs. Tested against:

• Sigstore TSA (Sigstore-operated public TSA, the cilock-action default)
• Self-hosted TSAs reachable over HTTPS

URL pattern: TSAs are passed via --timestamp-servers <url> (repeatable) or under run.timestamp-servers in the config file.

Evidence storage

Sink	Notes
File output	Default; via --outfile.
OCI registry	Via the oci attestor + downstream cosign/oras push.
Archivista	Tested against the in-toto/archivista reference server. URL pattern <platform-url>/archivista; auth via static --archivista-headers or OIDC (--archivista-oidc + --archivista-audience).

Witness compatibility

CI/lock shares witness's DSSE + in-toto envelope format, but interop is asymmetric — witness → CI/lock, not fully the reverse:

• CI/lock attestation type URLs use the https://aflock.ai/attestations/<name>/v0.1 namespace.
• Legacy witness URLs (https://witness.dev/attestations/<name>/v0.1) are accepted via aliases registered in attestation/legacy.go, called from main.go at startup via attestation.RegisterLegacyAliases().
• Witness-signed policies (DSSE payload type https://witness.testifysec.com/policy/v0.1) work with cilock verify.
• Witness-produced attestations verify under cilock verify.
• The reverse holds only for the shared base attestors. CI/lock's v0.3 Merkle-tree product/material attestations (tree:products root + inline leaves), standalone inclusion proofs, and trace records use predicates and verification logic witness doesn't implement, so witness verify cannot validate most CI/lock attestations.

Predicate types in scope

Predicate	Notes
in-toto Statement v1 (with versioned predicate URLs)	Native format for all CI/lock attestations.
DSSE envelope	Wraps every signed attestation.
SLSA Provenance v1	Emitted by the slsa attestor.
CycloneDX, SPDX	Embedded by the sbom attestor when found in products.
SARIF	Embedded by the sarif attestor when found in products.
VEX	Emitted by the vex attestor.

Version pinning recommendations

Dependency	Pin to
aflock-ai/cilock-action in workflows	A commit SHA (not a floating tag like @v1), see the defending-against-supply-chain-attacks tutorial for why.
cilock binary	A specific release version, not :latest, in any production-bound workflow.
Custom binaries built via the rookery builder	Pin every plugin module to a path-prefixed tag.

What's not covered

• Real-time network egress monitoring. CI/lock observes file/syscall activity, not network traffic. Pair with StepSecurity Harden-Runner for that gap.
• Developer laptop or production server protection. CI/lock operates in CI/CD only.
• Windows attestor coverage. Until the omnitrail build constraint is relaxed or made conditional, Windows requires a custom build.
