Performance team fixed iOS size reporting to measure only distributable packages, while runtime clamped down on RFC 9112 compliance for chunked encoding.

The iOS SizeOnDisk measurement now reports exactly one file instead of dragging in publish artifacts and debug symbols [1], mirroring an earlier Android fix that's already shipped. This cleanup matters because you can't trust your bundle size metrics if they're counting binlogs and dSYM bundles alongside your actual IPA. On the runtime side, SocketsHttpHandler tightened HTTP/1.1 chunk parsing to strictly require CRLF terminators per RFC 9112 instead of accepting lenient lone-LF sequences [7], closing a potential interop gap with stricter servers. The dotnet maestro pipeline hummed overnight, pulling source updates from nuget.client [2], the SDK [3], vstest [4], msbuild [5], and fsharp [6] into main. Android's MAUI integration added support for full ReadyToRun opt-in via MauiEnableFullReadyToRun [8], letting teams escape partial compilation when they need the performance ceiling.

Action items

→ Review iOS bundle size reports to ensure you're seeing clean IPA measurements without artifacts dotnet/performance [plan]
→ Test HTTP client code against stricter servers if you rely on chunk parsing edge cases dotnet/runtime [monitor]
→ Check MAUI Android builds for ReadyToRun configuration if targeting CoreCLR release perf dotnet/android [plan]
