    "evidence": "v2.2.1\n\nOctober 22, 2026 SECURITY: containers/alpine: Upgrade ca-certificates-bundle to 20261020-r0 to distrust eMudhra intermediate chains. containers/UBI: explicitly disallow emSign Root CA and Comodo AAA Services in the CA trust store to distrust eMudhra intermediate chains. core/policy: Fixed a cache-key collision vulnerability that could cause policy-name aliases to resolve to the immutable root policy. Root-policy aliases are now explicitly rejected at entity, group, token, authentication-response, and agent-registry policy assignment boundaries. Previously accepted root-equivalent policy aliases (e.g., \"./root\", \"a/../root\") are now rejected. CHANGES: core: Bump Go version to 1.27.3 to resolve CVE-2026-111943.",
