rdmbair15m5-changelog-20260822-0416-darwinscope-macos27-xcode-insights

Created comprehensive platform insights catalog, architectural guide, and interactive DarwinScope visual studio exploring macOS 27.0 (Darwin 27), Swift 6.4 concurrency safety, Swift Testing framework, on-device Core ML 4-bit ANE pipelines, and native macOS CLI power tools.

Scope

• Host: rdmbair15m5 (macOS 27.0 · Apple M5 · Swift 6.4)
• Projects: DarwinScope platform intelligence catalog

Exact files created on ~/Desktop/

• ~/Desktop/macos_xcode_novel_insights_and_features_v822.md (Technical catalog covering macOS 27, Swift 6.4, Swift Testing, CLI tools, Core ML ANE)
• ~/Desktop/macos_xcode_novel_insights_studio_v822.html (Interactive macOS Liquid Glass window render, feature navigator, CLI runner table, and code inspector)

Key Technical Systems Highlighted

1. macOS 27.0 Platform Features: Liquid Glass Material Pipeline, AppIntents v3, FileProvider v4, and asynchronous MetricKit.
2. Swift 6.4 Toolchain: Complete compile-time data race safety (Sendable, nonisolated), non-copyable types (~Copyable), and macro-driven package:Testing (@Suite, @Test, #expect).
3. Hidden Power CLIs: powermetrics, memory_pressure, brctl, fs_usage, ktrace, and scutil.

Verification Evidence

• Verified valid Markdown and interactive HTML5 studio files created on ~/Desktop/.
