Provenance Record

Strong 830-word News piece with depth across four substantive sections (announcement, multi-model routing, audit/checkpoints, pricing economics, security history). Tone is neutral, hedges appropriately on IBM's self-reported productivity figures. The 'What We Don't Know' section covers the right gaps (security remediation status, on-prem timing, productivity provenance).

All 3 source snapshots read; nearly every claim verified verbatim. • source-0.html.gz (PRNewswire/IBM press release): Confirms ARMONK dateline + April 28 2026; verbatim 'works across the full software development lifecycle (SDLC)…' quote; verbatim Dinesh Nirmal SVP IBM Software identification; verbatim Nirmal 'Every business is racing to modernize…' quote; 'Bob launched inside IBM in June 2025 with 100 developers' verbatim; 80,000+ employees + 45% productivity; IBM Instana 70% reduction = 10 hours/week verbatim; IBM Maximo 69% time savings verbatim; verbatim BobShell description; verbatim approval-model description; verbatim 'dynamically routes tasks to a suitable model based on accuracy, performance, and cost, drawing on a mix of frontier models including Anthropic Claude, Mistral open source models, and IBM Granite, alongside specialized fine-tuned models for code reasoning, security, and next-edit prediction'. • source-1.html.gz (VentureBeat, by Emilia David, Apr 28-29 2026): Confirms multi-model routing and human-checkpoint framing; '70% of time' '10 hours per week' figure; explicitly lists Anthropic Claude / Mistral / IBM Granite and 'smaller distilled models'; Pro at $20 / 40 Bobcoins, Pro+ at $60 / 160 Bobcoins, Ultra at $200 / 500 Bobcoins, 1 Bobcoin = $0.50 USD. **Does NOT contain 'code reasoning, security, and next-edit prediction'** — that exact phrase is from IBM's press release, not VentureBeat. Misattribution flagged in findings. • source-2.html.gz (The Register, by Joe Fay, Apr 28 2026): Confirms verbatim 'frontier LLMs, open-source models, small language models (SLMs) and IBM's Granite SLM family'; verbatim Holterhoff 'double edged sword…paralysis of choice' quote; verbatim '80,000 big bluers pressed into guinea pig status last year'; verbatim '$20 per month for the Pro tier with 40 Bobcoins, to Ultra at $200, with 500 Bobcoins'; verbatim 'What's a Bobcoin? About 50 cents, apparently'; verbatim Bob Premium Package for Z 'integrates and enhances the capabilities of IBM watsonx Code Assistant for Z…'; verbatim January 2026 vulnerabilities mention.

All factual claims are accurate. The only issue is one misattribution where 'code reasoning, security, and next-edit prediction' is credited to VentureBeat but is actually from IBM's press release.

APPROVE_WITH_CORRECTIONS. Strong substantive News piece on IBM Bob's GA. The chief:review script gave automatic APPROVE; manual snapshot review found one minor misattribution. The article is publishable as-is with the corrections record documenting the source-citation slip — not a content fabrication.
