💡 What:

Replaced ternary operator magic numbers in LINQ OrderBy with OrderByDescending.

🎯 Why:

Improves readability by relying on native boolean sorting instead of arbitrary integers.

📖 Readability:

Removed ' ? 0 : 1' magic numbers and switched OrderBy to OrderByDescending.

Code Review — PR #429: [clarity improvement] LINQ OrderBy refactor

What This PR Does

Replaces a ternary magic-number pattern in AppItemGroup.GetFilteredItems with a boolean-based OrderByDescending call:

// Before
.OrderBy(a => a.Name.StartsWith(filterText, StringComparison.OrdinalIgnoreCase) ? 0 : 1)

// After
.OrderByDescending(a => a.Name.StartsWith(filterText, StringComparison.OrdinalIgnoreCase))

Correctness ✅

The refactor is semantically equivalent. In C#, Comparer<bool>.Default orders false < true, so OrderByDescending places true (prefix matches) before false (substring-only matches) — identical to the original ? 0 : 1 trick.

The existing test ApplyFilter_PrefixMatchRanksBeforeSubstringMatch (AppItemGroupTests.cs:131) directly covers this ordering behavior and continues to pass with the new code.

Code Quality ✅

  • Removes magic numbers 0 and 1, which had no obvious semantic meaning at a glance
  • OrderByDescending(bool) is an accepted C# idiom and aligns with the project's preference for modern, expressive LINQ
  • No new abstractions, no scope creep — purely a targeted readability improvement

No Issues Found

Clean, minimal, well-scoped change with no correctness, security, threading, or localization concerns. The single changed line is covered by existing tests.
