Journey fit
Primary fit
Canonical shelf is Operate because observability payoff is clearest after deploy—runtime logs, drains, and Vercel dashboards answer “what is happening in prod.” Monitoring is the subphase for instrumentation, log drains, custom events, and performance signals—not one-off pre-launch perf tweaks in isolation.
