Provenance Record

Well-structured Briefing (597 words, within the 100-1000 range) using the standard Overview / What We Know / What We Don't Know / Analysis format. Prose is clear, technically precise (hub-and-spoke topology, conflict resolution policy, sync agent requirement for on-prem members), and appropriately scoped for a briefing-length piece. The Analysis section reasonably characterizes the retirement as following a familiar Azure end-of-life pattern without overstating what is known.

All 3 sources read directly from gzipped snapshots on disk (not re-fetched) and sha256-verified against manifest.json (source-0.html.gz: 297f6f4d..., source-1.html.gz: 139e51d3..., source-2.html.gz: efd8a00b... — all matched). source-0.html.gz (The Register, Richard Speed, published Thu 10 Sep 2026 15:47 UTC): confirms the Sept 9 restriction date, Sept 30 2027 shutdown, hub-and-spoke model with sync agent requirement for on-prem members, conflict resolution policy, hybrid/distributed/globally-distributed use cases, the 'operational, security, and compliance requirements' quote, the alternatives list (Azure Data Factory, Azure Functions, read replicas, linked servers, mirroring, availability groups, transactional replication), the 'there is no single replacement that maps to every SQL Data Sync configuration' quote, and the 'announced two years ago' claim. source-1.html.gz (Microsoft Learn, 'What is SQL Data Sync for Azure?'): confirms the verbatim quoted passage 'As part of the retirement process, you can't create new sync groups in Azure subscriptions that didn't previously use SQL Data Sync. Existing sync groups can continue operating until the retirement date,' the hub-and-spoke/'sync occurs only between the hub and individual members' architecture, and the Hub wins/Member wins conflict resolution policy. source-2.html.gz (Microsoft Learn, 'SQL Data Sync retirement migration'): confirms the Sept 30, 2027 retirement date, the three named scenarios (Hybrid data synchronization, Distributed applications, Globally-distributed applications) attributed correctly to this page rather than to source-1, and the identical alternatives list organized by use case. No misattribution found; every direct quote in the article appears verbatim in its cited snapshot; no orphan source URLs (all 3 sources array entries are cited in the body and vice versa).

Every specific claim (dates, percentages n/a, the hub-and-spoke architecture, the conflict-resolution options, the two Microsoft doc quotes, and the alternatives list) traces directly to a cited source and was independently confirmed against the raw snapshot text. No hallucinated or unsupported specifics detected.

Clean, well-sourced Briefing with all claims and quotes verified against the underlying snapshots. No corrections needed. Approved.
