One revised LDL-C result shows where custody of clinical trial data breaks: at the handovers between laboratory, CRO, and sponsor. What 21 CFR Part 11, ICH E6(R3), and EMA guidance expect at each handover, and how to engineer a record of it.

A modernised government system can work perfectly and still leave its auditors short of evidence, because the history the old system kept was lost in the move.

API Governance Done Properly, we follow one eligibility API through a public sector programme twice: first governed by a review board and a spreadsheet, then by the platform it runs on.

A sovereign cloud contract usually covers the platform, while keys, identity, data rules, telemetry, and testable contract terms decide whether sovereignty holds. Five decisions that procurement and engineering should make them together, early.

Agents absorb much of the work junior engineers used to learn judgement on.

Which leaves a career ladder built on senior judgement sitting on a pipeline that no longer produces it.

Faros Research, 10,000+ developers: teams with high AI adoption merged 98% more PRs. Review time up 91%.

The second number is what decides whether the programme pays for itself.

Part 2 does the arithmetic.

New white paper: The CTO Playbook for Agentic Systems. 71 pages on running an engineering organisation whose software has started writing itself.

Nine parts, nine deliverables, one 28-question readiness assessment.

The CTO Playbook for Agentic Systems

A 71-page operating manual for engineering leaders whose software has started to reason, decide, and write the software that carries out those decisions. Written by our CTO, Andrew Stevens.

Tollgate v0.2.3: What Long-Context Pricing Does to a Spend Cap Some models bill the whole request at a higher rate above a size threshold. What that does to a spend cap, and what changed in Tollgate between v0.1.1 and v0.2.3.

GATE v1.5 Roadmap

Preview the next GATE release: per-control ISO/IEC 42001 mapping, streaming-aware output validation, an end-to-end ADK reference implementation, a public playground, and the fuzzing work that v1.4 deferred.

Tollgate: Open-Source Hard Limits for LLM Spend

It prices every LLM request by token, reserves budget before the call, and refuses over-budget requests with a 402 before they reach the provider. Rust, MIT, Anthropic and Vertex, deploying to Cloud Run.

GATE v1.4 is out.

Adds C20, formalises break-glass as a signed contract, adds informative mappings to OWASP AISVS, MITRE ATLAS and NIST SSDF, and ships three new repositories: gate-rust, gate-fuzz, and gate-knowledge.

Protecting the IP in a Generative World

A studio can find its back catalogue inside a public model’s training data and discover it cannot prove, from its own systems, when the work was made or that anyone ever ingested it.

Your System Prompt Is Not a Trust Boundary

A text-to-SQL agent’s system prompt cannot enforce a data rule. sql-guard v0.2.0 puts the rule in a parser instead, and closes eight bypasses found in our own guard.

AI declared a strategic priority + no named executive owner + no success metrics = a science project with a budget line.

The Executive AI Playbook on why ownership comes first.

Read the first edition of the Executive AI Playbook? You don't need to reread 65 pages. The what's-new page lists every v1.1.1 addition with deep links. The diff is the news. https://t.co/joCS2Ua6tD

Arkhe: An Ontology Language for AI Systems

Arkhe v0.2 is out: entities, relationships, and guarded actions in one YAML file, compiled into the artifacts AI systems consume. Here is what it is, who it is for, and what it deliberately refuses to be.

[Sakura Sky @sakuraskycom]

The first Executive AI Playbook assumed a model that suggested and a human that decided. That assumption no longer holds. v1.1.1 covers what changed: agents that act, costs falling 10x a year, new sourcing paths.

Fraud, financial crime, KYC, and customer experience have collapsed into a single engineering question about who the customer is. A unified identity layer is the foundation a modern bank runs on.

Sovereign cloud commitments are usually scoped as a hosting decision, while a bank’s real exposure sits in the data flows that cross the boundary. This second post in Financial Services Engineering series.
