Live Holtburg at 2560x1440: the Low preset needed 67,368,164 resident bytes (screen-sized HDR/depth/ray targets are 44 MB of that) against an absolute 64 MiB ceiling that had only been validated at 1080p, so Options -> Apply fell back to the default path; every later Apply was then refused by the controller's failure memo, which treated the user's deliberate choice like automatic re-activation. RenderPackResidentBudget.Effective scales the declared 1080p figure by the viewport's pixel-count ratio (never below 1), still capped by the hardware MaxPackResidentBytes; both pack graphs use it and the performance-matrix tool judges its resident column by the same rule (contract test updated). RenderPackController.Request gains explicitUserChoice, which clears the memo for that selection; RenderPackSelectionBinding passes it on every display edge (Apply, including resolution changes) and keeps the memo for the startup request. Tests: RenderPackResidentBudgetTests (1080p/720p keep the declared ceiling, 1440p = 16/9x, 4K = 4x, hardware cap wins, zero extent rejected); controller explicit-retry; the binding test now proves the user's next Apply activates once the cause is gone. App hermetic lane 6,068/0 (Release). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
