Retrofitting Observability Costs 10x — What 'Day One' Actually Means
We cut service onboarding from three days to thirty minutes, but only for services that adopt the template on day one. The three days is where retrofit lives: reverse-engineering what to instrument, adding correlation IDs to a printf codebase, backfilling resource attributes, and finding cardinality bombs in production. Day one is a concrete checklist, not a good intention.
