- Around line 17-27: Validate all dimensions at the HistoryTableColumnLayout
model boundary: update width(for:viewportWidth:minimumWidth:) to require a valid
layout, finite positive viewportWidth, and finite nonnegative minimumWidth,
returning a safe fallback otherwise; update resizeColumn(_:to:viewportWidth:) to
reject invalid layouts, non-finite or nonpositive width, and non-finite or
nonpositive viewportWidth before scaling, preserving the existing layout on
invalid input.

Validate dimensions before scaling.
The coordinator rejects zero and negative viewport widths, but its > 0 checks allow +∞. width(for:viewportWidth:minimumWidth:) can then return a non-finite width. resizeColumn(_:to:viewportWidth:) can also write non-finite scaled widths and an invalid reference viewport. Validate these dimensions at the model boundary and preserve the layout when resize input is invalid.
Proposed validation
func width(for column: String, viewportWidth: Double, minimumWidth: Double) -> Double {
+ guard isValid,
+ viewportWidth.isFinite, viewportWidth > 0,
+ minimumWidth.isFinite, minimumWidth >= 0 else {
+ return minimumWidth.isFinite ? max(0, minimumWidth) : 0
+ }
max(minimumWidth, (widths[column] ?? minimumWidth) * viewportWidth / self.viewportWidth)
}
mutating func resizeColumn(_ column: String, to width: Double, viewportWidth: Double) {
+ guard isValid,
+ width.isFinite, width > 0,
+ viewportWidth.isFinite, viewportWidth > 0 else { return }

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
