CS-01 A Telegram channel, hardened like a production banking gateway.

Eighteen controls in five layers: gateway, identity, session isolation, behavioural rules and operations. The same hardening pattern bank procurement committees ask architects to apply to third-party chat channels.

CS-02 Agentic KYC - unravelling corporate UBO across jurisdictions.

Enhanced CDD, adverse-media screening, and beneficial-ownership unwind under AMLR Article 42 and the BORIS register. Research swarms and vision agents as proof-of-build components - the AFC transformation shape banks are budgeting for in 2026.

CS-03 Multi-model orchestration without vendor lock-in.

Nexus routes across GLM, MiniMax, Birch, Gemma, and Claude with a fallback chain that survives a provider outage mid-task. The vendor-independence pattern DORA Article 28 now asks banks to design for.

CS-04 Agentic AI across the consumer-lending lifecycle.

Origination through servicing - PSD2/3 data aggregation, document ingestion at application time, affordability beyond traditional credit scoring, real-time decisioning, back-book repricing. Same component-level proof-of-build anchoring under PSD3 and AI Act Annex III.

CS-05 Cron-Driven Autonomy

The operational layer that keeps a multi-agent system honest while nobody is watching - the upgrade pipeline, the verification discipline, and the guardrails under DORA Art. 17.

CS-06 When the watcher couldn't be trusted.

A model-failover watcher that flipped a healthy system onto a fallback in a tight loop - because the cloud was rate-limiting, not failing. The boundary between monitoring and decision-making under AI Act Article 14.

CS-07 The bleed - AI compute as a treasury function.

Two paid-API leaks caught by a balance poller on a daily timer. The forensics, the two rules that fell out, the observer-based circuit breaker that enforces them, and the case for treating production agentic compute as a treasury function.
