The routing table

Five workloads, each with its own rule. Overrides are allowed, but logged with a reason.

• Visibility checks, run constantlymonitoringFast, small modelsFrontier models are forbidden on this path - at scale the cost ceiling breaks immediately. A premium plan buys more samples and more engines, never a bigger monitoring model.
• Judging what an engine got rightfidelityMid-weight · frontier at premiumAccuracy adjudication runs a mid-weight model; premium tiers escalate to frontier.
• High-volume short-form copypin_copyFast, small models · every tierA batch of 75 pins times several calls each cannot afford a frontier model, and short brand-voiced copy does not need one.
• Long-form strategy documentsdeliverableWorkhorse to frontier, by roleNarrative sections run the workhorse class many times per document; synthesis-heavy documents and the point-of-view letter escalate to the most capable model available. On an upstream error the call falls one tier with a logged warning - never a silent substitution.
• Strategy briefsbriefAlways frontierRegardless of tier - opt-in and low volume, so the ceiling holds.

When a vendor ships a new model family, the swap is one table entry - shipped to every product at once.
