F1 2026: Upgrade-Package Calendar Against Remaining Circuit Archetypes

A weekly join of two schedules that teams manage against each other and that are rarely published together: when each constructor is bringing developments, and what the remaining calendar actually demands. The upgrade side tracks declared packages by event, split between aerodynamic and power-unit-side work, alongside each team's current aerodynamic testing allocation — the sliding scale that hands wind tunnel and CFD time to teams by inverse championship position and resets mid-season, so a team's development rate is partly a function of where it already sits — and its remaining cost-cap headroom. The circuit side classifies every remaining round by archetype in terms that matter under the current regulations: low-drag power circuits, high-downforce corner circuits, traction-limited exits, high-altitude rounds, and the energy-limited layouts where the fifty-fifty split between internal combustion and electrical deployment plus the removal of the heat-recovery unit makes battery management, not peak downforce, the binding constraint. Joining them gives an archetype-fit index per constructor: whether the developments arriving are aimed at the circuits still left. Method: package declarations are collected from the documentation teams submit at each event and from technical-media reporting on those submissions, testing allocations derived from published championship standings against the regulated sliding scale, cost-cap headroom estimated from published financial filings and reported spend, and circuit archetypes coded from lap-telemetry characteristics such as full-throttle percentage, average corner speed, and elevation.
