Implementations
Systems in production, with the numbers they produced and a named failure mode. Where those are missing the note says so instead of estimating.
Two separate things are reported here and they are easy to confuse.
State is the system: whether it runs in production, is complete, or is retired.
Note not written is this site's problem rather than the system's, and it means the
figures and the named failure mode have not been supplied for publication. A system can be
in production for years with nothing written about it here, and several are.
Principle 4.8 refuses an architecture without a named failure mode, so those pages carry
front matter and an explanation rather than an estimate.
| § | System | Result | State |
|---|---|---|---|
| 3.1 | Mevrik: agentic customer experience platform Multi-tenant conversational automation for banks and telecom operators. One image ships to public cloud and to air-gapped estates, and configuration alone decides which. Go · Python · TypeScript / Next.js · Flutter · gRPC + protobuf · PostgreSQL + pgvector · ClickHouse · Redis · NATS JetStream · MinIO / S3 · Docker · Kubernetes · Helm · OpenTelemetry | 3M+ conversations/month 99.9% against contracted SLAs | production |
| 3.2 | Sovereign LLM gateway One control plane over several model backends, the self-hosted ones running on two GPUs we own. Redaction runs before routing, fallback is deterministic and stamped, quotas are per tenant and per model. Python (FastAPI) · Redis · OpenSearch · PostgreSQL · Ollama · Qwen · open-weight models only · 2 GPUs, self-hosted inference | no figures supplied | production |
| 3.3 | Webhook ingestion with delivery guarantees A shared receiver for API and social media callbacks. Every event is accepted once, replayable forever, and never lost because a downstream service was having a bad afternoon. Rust (tokio) · RabbitMQ · PostgreSQL · MinIO | 100% webhook receipt rate | production |
| 3.4 | Analytics migration to ClickHouse Moving analytical workload off a row store onto a columnar one without downtime, under dual writes, with the rollback built before the cutover rather than after it. ClickHouse · Kafka Connect · Airflow | no figures supplied | complete |
| 3.5 | Air-gapped delivery pipeline Shipping software into estates with no network path back, as one complete signed artifact, installed by an operator who cannot ask you a question. OCI bundles · cosign · Helm · offline registry | no figures supplied | production |
| 3.6 | Audit evidence programme Evidence generated by the pipeline that does the work, not assembled by a person the month before an audit. Built for ISO 27001, GDPR and BNM RMiT, and for the client security reviews that decide contracts. ISO 27001 · GDPR · BNM RMiT · SOC 2 Trust Services Criteria · DevSecOps · CI release gating · vendor risk | no figures supplied | production |
| 3.7 | Voice AI for customer service Inbound and outbound voice agents on the Omazy CX platform, with Bangla and Banglish speech in production and live handoff to a human under SLA routing. streaming STT · TTS · telephony · retrieval grounding · Bangla / Banglish | no figures supplied | production |
| 3.8 | Custom LLM training and hosting Open weight models fine tuned and served on self managed GPU infrastructure for clients whose data cannot reach a public API, with promotion gated on evaluation. LoRA / PEFT · self-managed GPU · quantisation · model registry · private cloud / on-prem | no figures supplied | production |
| 3.9 | A constant tool surface over an unbounded API surface An MCP server that lets an agent operate any API with an OpenAPI description, through a fixed handful of tools rather than one tool per endpoint, with multi-step recipes and credentials that never reach the model. TypeScript · Model Context Protocol · Astro SSR · Cloudflare D1 · Cloudflare KV / R2 · JSONPath · Server-Sent Events | no figures supplied | production |
| 3.10 | Attendance as a ledger, and the line it eventually bills One append-only record of who was where, projected into payroll truth, a dispatch estimate and a liveness indicator, and carried through to the invoice line it justifies. append-only ledger · projections · mobile capture · geofencing · payroll export · revenue attribution | no figures supplied | production |
