Verify the signatures

All three artifacts are signed keylessly through Sigstore. Each certificate identity is this
workflow at the ref that performed the release, so a signature from any other workflow,
ref or repository fails:

cosign verify \
  --certificate-identity https://github.com/beyond10x/substrate/.github/workflows/release.yml@refs/tags/0.5.0 \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com \

What this release does not claim

• The published wire contract remains a development bundle.
  ghcr.io/beyond10x/b10x-substrate-wire:0.15.0 remains a development bundle; OCI publication,
  digest pinning and a verified signature do not make it a stable contract. A
  stable-contract decision is its own ADR under atlas ADR 0019
  (architecture/adr/0019-substrate-contract-release-and-conformance.md).
• The image's default posture is development, not hosted. Its EXPOSE 8080 and
  VOLUME describe the static-bearer TCP posture that design 06, section 1, marks
  development_only. The binary also implements the production TLS/Identity profile,
  but a hosted deployment must explicitly supply that profile's certificates, trust
  roots and authority settings; the default container command does not do so.
• The MCP image is local test tooling, not production ingress. It has no listener,
  authentication or remote transport and is intended for an attached stdio harness with
  --network=none. Its tool surface is not a stable contract independent of Substrate.
• The binary is not bit-for-bit reproducible. The digest above is recorded;
  reproducing it from source independently is a later milestone.
• The delegated execution lane is not exercised by CI. A host without a delegated
  cgroup v2 subtree answers exec.sandbox-unavailable rather than running unconfined.
