quick-bounce-assessor
Assesses macOS/SwiftUI app launch and runtime performance. Evaluates first-frame ('quick bounce') readiness by finding synchronous main-actor I/O on the launch path, Swift strict-concurrency posture, view-model vs business-logic separation, and steady-state render budget (high-frequency @Published timers, per-body allocations). Produces a PASS/WARNING/FAIL report with file:line evidence and phased fixes. Use when reviewing a macOS/SwiftUI or AppKit app for launch responsiveness, concurrency safety, or UI smoothness.
