2. ✅ Merge ready PRs — #5655 (CLI perf), #7535 (reflection cache), and #7597 (Polyfill removal) appear close to ready.

3. 🔬 Review Assert.Scope() — PR #7355 introduces soft assertions, a frequently requested feature. Early review feedback would help shape the API.

4. 🧹 Triage Assert.That issues — Issues #6690 and #6691 both touch Assert.That correctness and could affect user trust in assertions.
