Every published Sencho Docker image is now signed with Sigstore cosign
using GitHub Actions keyless OIDC, and ships with an embedded SBOM plus
SLSA provenance attestation attached as OCI referrers on the image.
Users can verify the signature and inspect the attestations themselves
before pulling an image into production.
cosign verify saelix/sencho:<tag> \
--certificate-identity-regexp "https://github.com/AnsoCode/Sencho/.*" \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
The release pipeline now also publishes a new moving minor tag
(saelix/sencho:X.Y, e.g. 0.42) alongside the existing latest and
immutable X.Y.Z tags, so operators who want the latest patch on a given
minor line can pin without chasing every release. Since every 0.x minor
is potentially breaking, the {{major}}-only tag is deferred until 1.0.
cosign is installed via the sigstore/cosign-installer action pinned to
a full commit SHA. The signing step batches every tag produced by
metadata-action into a single cosign invocation pinned to the built
digest, so all tags resolve to the same manifest and we save N-1
Rekor/Fulcio round trips. The job declares id-token: write so the
ambient OIDC token can be minted.
A new docs page (docs/reference/verifying-images.mdx) walks users
through installing cosign, verifying an image, and inspecting the SBOM
and provenance with docker buildx imagetools. A note calls out that
signatures start shipping with v0.43.0, so older images failing
verification is expected behavior and not tampering.
