Summary

SystemStatusIndicator drove its spinning gear with Timer.publish(every: 1/60) that never stopped, so the main thread woke 60 times a second for as long as the indicator existed, long after validation finished.

The angle is now a function of time inside TimelineView(.animation(paused: animationPhase == .stopped)):

• spinning: 180°/s from the angle where the spin started
• decelerating: the integral of the old (1 - t)^2 speed curve over 0.6 s
• stopped: the timeline pauses; a .task(id:) moves the phase to stopped when the slowdown ends

Unused state (isAnimating, rotationSpeedDegPerSec) and import Combine are removed.

From the architecture review's next tier ("60 Hz timer never stops").

Testing

• swift build passes; swiftformat --lint (0.61.1) is clean.
• Not checked visually. KeyPath is uninstalled on the Air, so the spin and the slowdown have not been watched in the running app.

Review: no actionable findings.

I checked the new time-derived rotation in SystemStatusIndicator.swift:

• The deceleration integral is correct: v·D·(1−(1−t)³)/3 is the integral of the (1−t)² speed curve.
• The angle stays continuous across phase changes, because phaseBaseDegrees is re-based at each transition.
• Interrupting a slowdown with a new .checking state is safe. startSpinning changes phaseStart, which cancels the old .task, and the animationPhase == .decelerating guards cover any task that is already running.
• Pausing TimelineView once the phase is .stopped removes the always-on 60 Hz Timer, as intended.

Minor, non-blocking: there is no automated coverage for the phase math. If it's cheap, pull rotationDegrees(at:) into a pure static function so it can be unit-tested. Please also confirm the spin-to-stop transition by eye in a deployed build.
