Live Dashboard Update Verification

Core outcomes

• Data-to-interface failure boundary identification
• Shared target ownership and mount-lifetime verification
• Complete first-snapshot and successive-event browser evidence
• Separate value, collection-status, revision, and freshness interpretation
• Retained focus and reading state across live updates
• Semantic browser assertions under the production content security policy

Requirements

Preconditions an agent should verify before selecting this capability.

• Dashboard with an identifiable snapshot or event update contract
• Access to affected source, build configuration, and browser test commands
• Controlled fixture or authorized live observation source
• Real browser execution with the application's content security policy enforced
• Observable transport, accepted state, and DOM update boundaries

Boundaries

Published limitations that constrain safe use.

• Synthetic browser evidence does not prove live collector or provider health
• Known zero, blocked, stale, unknown, and collection failure remain distinct
• A replacement node matching a selector does not prove original target continuity
• Desktop, mobile, reconnect, and replay coverage are claimed only when exercised
• Verification does not authorize production writes to manufacture update events
• A bounded update-path result is not a whole-application health claim
