v1.5.2

CK.Lib.Js — latest published artifacts

One publishable surface ships from this repo: the OCI static bundle (ckp:static designation) — the CKP concept-kernel JS client (dispatch-only) shipped as a Shape A filesystem-layer OCI image per SPEC.OCI.BUNDLE.v0.4. The npm package @conceptkernel/cklib is staged in package.json but not yet released. See Repo packages view for the full version history.

CK.Lib.Js OCI bundle — v1.5.2

Per PROVENANCE.md, every digest below verifies under gh attestation verify oci://… --repo ConceptKernel/CK.Lib.Js. Versions before v1.3.9 predate the attestation wiring and never appear here — re-publishing them would change digests and break the immutability promise.

docker pull ghcr.io/conceptkernel/ck-lib-js:1.5.2 → declare as a static_web (routed) or layer_sources (additive merge) entry in your bundle.yaml per SPEC.OCI.BUNDLE.v0.4. The bundle lands the facade + transport + cache at image root (/ck.js, /ck-client.js, /ck-store.js, /vendor/) ready for spec-standard COPY --from=cklib_source / dest/.

Verifying any artifact above

# Multi-arch index (Docker's manifest negotiation picks the right arch)
gh attestation verify oci://ghcr.io/conceptkernel/ck-lib-js:1.5.2 \
  --repo ConceptKernel/CK.Lib.Js

# A specific per-arch leaf
gh attestation verify oci://ghcr.io/conceptkernel/ck-lib-js@sha256:bcd4328ff6513f6df7f93918d8ad42b9e231281c860a5f4d640c9635ab4428fe \
  --repo ConceptKernel/CK.Lib.Js

A successful verify means: signed by GitHub's Fulcio CA against the OIDC token of the v1.5.2 oci-publish workflow run, recorded in Sigstore's Rekor transparency log, subject digest matches the pulled artifact.

Use as static layer

In your bundle.yaml (per SPEC.OCI.BUNDLE.v0.3):

spec_version: 0.3
# Shape A — routed mount under a path the FastAPI/static server exposes:
static_web:
  - source_image: ghcr.io/conceptkernel/ck-lib-js:1.5.2
    route: /cklib
    attestation_repo: ConceptKernel/CK.Lib.Js
# …or additive filesystem merge into the final image:
layer_sources:
  - source_image: ghcr.io/conceptkernel/ck-lib-js:1.5.2
    into: /app/cklib/
    attestation_repo: ConceptKernel/CK.Lib.Js

The build MUST run gh attestation verify oci://ghcr.io/conceptkernel/ck-lib-js:1.5.2 --repo ConceptKernel/CK.Lib.Js before the consuming image is pushed (SPEC.OCI.BUNDLE.v0.3 §4 build-time gate).

Browser consumption (after the bundle is mounted at /cklib/):

<script type="module">
  import { CKClient } from '/cklib/ck-client.js';
  const ck = new CKClient({ kernel: 'pgCK.Task' });
  await ck.connect();
</script>

Pin policy

• latest tracks the most recent attested CK.Lib.Js tag on the multi-arch image index. Both arches resolve transparently via Docker's manifest negotiation — no latest-amd64 / latest-arm64 split.
• Tagged versions are immutable on GHCR. Pin by version (1.5.2) in production bundles; use latest only for development.
• The OCI bundle is anonymous public pull — no GHCR auth required.
• Per PROVENANCE.md Rule 2: do not consider an artifact "shipped" if its digest does not verify under gh attestation verify.

See CHANGELOG.md for what changed per version, COMPLIANCE.md for the transport contract, README.md for the CK concept-kernel API.
