Architecture case-study blueprint: no deployment results, customer endorsement, or measured improvements are claimed.
Data and operating scope
Gather release versions, error signals, dependency status, and the approved rollback runbook.
Deterministic solution
Evaluate configured thresholds and release checks, then route the incident to the service owner.
Agentic solution
Correlate changes with symptoms and prepare investigation or rollback proposals.
Acceptance evidence
Time-aligned evidence, alternative hypotheses, permission checks, and verified recovery criteria.
Decision boundary
A plausible root-cause hypothesis is not a confirmed diagnosis. Production changes require explicit authority, bounded actions, tested rollback, and accountable operators.
