Report #45386

[frontier] Deploying agent updates risks production stability; A/B testing is too coarse for agent behavior validation

Run shadow agents in production that receive live traffic but execute in dry-run mode \(observing but not acting\); compare shadow outputs to production agent via semantic diff to validate before cutover

Journey Context:
Agent behavior is non-deterministic; unit tests insufficient. Shadowing validates against real user distributions without user impact. Enables safe iteration on prompts, models, and tool chains.
