Content Quality: Clean, well-structured News piece (Overview / What We Know / What We Don't Know / Access) at 626 words, within the 400-1200 News range. Technical claims about Neki's architecture (routers, shard groups, sidecars, control plane, data topology) are presented clearly and map directly to the source material's own structure.
Source Verification: All 4 sources fetched successfully (HTTP 200, no archive fallback, no suspicious_patterns in manifest.json). Independently re-verified sha256 of all 4 snapshots by gunzip + sha256sum against manifest.json values — all matched exactly. Read all 4 snapshots in full via gzip decompression + HTML text extraction (not WebFetch): (1) source-0.html.gz (planetscale.com/blog/introducing-neki, 'Introducing Neki' by Nick Van Wiggeren, dated September 10, 2026) confirms every quoted sentence in the Overview and 'What We Know' sections verbatim, including the router/shard/sidecar/control-plane descriptions, the __neki metafunction workflow language, and the platform-preview disclaimer sentences ('You should not run production workloads on Neki during the platform preview,' 'The product is still changing, and some of those changes will be breaking'). (2) source-3.html.gz (planetscale.com/blog/announcing-neki, 'Announcing Neki,' dated August 11, 2025) confirms the August 2025 first-unveiling date, the verbatim quote 'Today, we are announcing Neki — sharded Postgres by the team behind Vitess,' and the exact 9-author byline order (Andres Taylor, Dirkjan Bussink, Harshit Gangal, Nick Van Wiggeren, Noble Mittal, Rohit Nayak, Roman Sodermans, Shlomi Noach, Sam Lambert) matching the article precisely. (3) source-1.html.gz (planetscale.com/docs/neki) confirms the verbatim quotes 'Vitess already runs some of the largest services on the internet, including Slack, Square, and Cursor,' 'is not a Vitess port,' 'is built from scratch to specifically solve the scalability and operational challenges of Postgres,' 'You do not have to shard to use Neki. A new database starts as an unsharded cluster,' the Beta Features / no-SLA disclaimer, and the platform-preview access instructions including 'Neki then appears as a database engine.' (4) source-2.html.gz (neki.dev) confirms the verbatim capacity claims '100M+' queries per second, 'PB+' of data per database, '0 downtime' resharding, and the 'Coming soon' status for cross-shard transactions. No hallucinated quotes, no unsupported specifics, and no orphan source URLs (all 4 body-cited URLs appear in article.sources and vice versa).
Factual Accuracy: All specifics (dates, author list, quoted figures, capacity claims, feature status) trace verbatim to a cited, verified source. No fabrications detected.
Overall Assessment: High-quality, accurately sourced product-launch News piece. All 4 claims-bearing sources were read in full and every quote/specific verified verbatim, including the specific Vitess-vs-Neki attribution risk flagged pre-review, which the article handles correctly. The only automated finding (sources not in allowlist) is a config bookkeeping gap rather than a content defect, consistent with prior precedent (2026-09-03 Polars review) for verified single-vendor primary sources; resolved by adding planetscale.com and neki.dev to config/source_allowlist.txt rather than by filing a corrections record. Verdict: APPROVE.
