Summary

Works primarily in JavaScriptCore — Wasm (validation, JIT callee publication, calling-convention register handling) and DFG OSR availability — with a secondary line in CMake and build configuration, including warning enablement across the Cocoa ports. The security-relevant commits split into two themes: GC lifetime correctness (a missing write barrier in `Array.unshift`, weak-reference handling for DeferredWorkTimer tickets and swapped JSString impls under `GCOwnedDataScope`, JSDOMException stack-trace reconciliation) and Wasm validator type widening, where same-day fixes covered block types, `delegate`, and unreachable `end` ops. Systematic-variant candidate: the widening cluster reads as a sweep of the unreachable-code path in Wasm validation rather than a one-off patch, so remaining opcodes that terminate or rethread control flow are the natural place to keep pulling.
