The through-line across yesterday's work is boundary correctness. Six focused fixes landed, and each corrects a case where React quietly returned the wrong file, the wrong value, or missed an event entirely.
First, debugging accuracy in DevTools. Two changes tighten how stack frames resolve through source maps. One, in pull request 38238, fixes lookups at the end of a generated line, where the wrong mapping could point you to the wrong source file and misclassify app code as vendor code. The other, in 38239, fixes…
Second, Flight data fidelity. Two changes keep server-to-client values intact. Pull request 38241 preserves invalid dates instead of turning them into null during serialization, in both directions. Pull request 38242 prevents unpaired surrogates from being corrupted when strings move through UTF-8 text chunks. If…
