Provenance Record

Clean, well-structured News piece (507 words, within the 400-1200 range). Overview/What We Know/What We Don't Know/Analysis format, appropriate technical depth, every sentence carries an inline 'according to' attribution. Paraphrase throughout; no direct quotes are placed in quotation marks (the only quoted string is the code literal new KVStore(scope, 'todos'), which matches InfoQ verbatim).

All three source snapshots read from disk (sources/2026-07/aws-releases-blocks-in-preview-an-open-source-typescript-framework-that-bundles-application-code-and-cloud-infrastructure-for-ai-agents/). source-0.html.gz (AWS what's-new, HTTP 200) CONFIRMED: 'Jun 16, 2026' announcement date, open-source TypeScript framework framing, local Postgres/auth/real-time environment with no AWS account, same code runs on production AWS with zero changes, drop into AWS CDK, built-in guidance for AI coding tools, end-to-end type safety without a code-generation step, no additional charge / pay only for AWS services, deploys to all commercial AWS regions, npx @aws-blocks/create-blocks-app. source-1.html.gz (InfoQ, HTTP 200) CONFIRMED: 'approximately 20 Blocks', full service mapping (Postgres via Aurora, DynamoDB, Cognito, Bedrock knowledge bases, S3, real-time messaging, background jobs, scheduled tasks, SES), steering files, KVStore in-memory/DynamoDB/Lambda SDK progression, frontend list (Next.js, Nuxt, Astro, React, Vue, Svelte, Angular) and native clients (Swift, Kotlin, Dart/Flutter), Amplify vs Blocks distinction (hosting/CI/CD/managed vs type-safe infrastructure-from-code, local-first), and the 'Designed for AI Agents to Build Backends' headline. source-2.html.gz (GitHub aws-devtools-labs/aws-blocks, HTTP 200) CONFIRMED: Apache-2.0 license and the repo description 'Composable building blocks for full-stack AWS apps - define infrastructure and runtime code together with end-to-end type safety using TypeScript'. All three sources are on the allowlist.

Every specific traces to the source that actually carries it, per the review brief: framework name (Blocks) and Apache-2.0 licensing to GitHub; the ~20 Blocks figure and service mapping to InfoQ; the June 16 2026 date, pricing (no additional charge), commercial-regions availability and scaffold command to AWS. No hallucinated figures or misattributions detected.

High-quality, fully-sourced submission. All integrity checks pass, all three snapshots personally read and each claim confirmed against the source that carries it. Approved for publication as-is.
