Provenance Record

Clean, well-structured News piece (481 words, within the 400-1200 News range). Overview / What We Know / What We Don't Know / Analysis structure is appropriate. Technical depth is accurate and accessible; opt-out APIs (ChangeDetectionStrategy.Eager, provideHttpClient(withXhr)) are correctly contextualized.

All 3 source snapshots read from disk; sha256 of each decompressed snapshot matches manifest.json (source-0 ebdf1f06, source-1 5c05bfbb, source-2 de62c47c). source-0 (angular.dev/events/v22, 200): release marker '2200-2026-06-03' present, and the quote 'Signal Forms, Asynchronous Signals, and Angular Aria are now stable, offering a production-ready reactive foundation' is verbatim. source-1 (raw CHANGELOG.md, 200): v22.0.0 header is '# 22.0.0 (2026-06-03)'; 'graduate signal forms APIs to public API', the OnPush-default sentence with ChangeDetectionStrategy.Eager, the provideHttpClient(withXhr) sentence, and 'TypeScript versions older than 6.0 are no longer supported' all appear verbatim under the v22.0.0 entry. source-2 (angular.dev/guide/testing, 200): 'covers the default testing setup for new Angular CLI projects, which uses Vitest' is verbatim and @angular/build:unit-test is present. No source was fetched via Archive.org fallback; no snapshot failed. The bot-blocked Medium-redirecting blog post is NOT cited in the body or in article.sources.

Every feature specific (Signal Forms / Asynchronous Signals / Angular Aria stable; OnPush default for new components; TypeScript 6 floor; Vitest default test runner; Fetch-default HttpClient) and the June 3, 2026 release date trace to the official Angular CHANGELOG v22.0.0 and angular.dev primary publications, satisfying Rule 9. All quoted tokens verbatim. No fabricated specifics.

APPROVE. All claims, quotes, specifics, and the release date verified verbatim against the primary Angular sources. The only finding is a non-blocking allowlist warning, which does not warrant a corrections record (no factual error or misattribution exists). High-quality submission ready for publication.
