001Operating problem

Connecting a model to an API is a small part of systems integration. Production value depends on authoritative data, stable semantics, identity, policy enforcement, recoverable messaging, lineage, and acceptance evidence across every participating system.

P01

Two systems may exchange valid JSON while disagreeing about identifiers, timestamps, units, state, confidence, or who owns the record.

Decision question

Which contract defines meaning, authority, freshness, validation, and change for every exchanged field and event?

P02

Service credentials, user delegation, device identity, and model tool calls create different access paths that must be evaluated continuously.

Decision question

Which subject may access which resource for which purpose, and how is that decision enforced and audited at each boundary?

P03

Retries, duplicates, partial writes, late events, back pressure, unavailable dependencies, and incompatible releases can silently corrupt a workflow.

Decision question

What are the timeout, retry, idempotency, queue, reconciliation, rollback, and dead-letter behaviours for each interface?

P04

When a decision is challenged, teams need to connect the source record, transformation, policy, model version, approval, and downstream write.

Decision question

Can an operator reconstruct what happened without relying on logs that use unrelated identifiers or omit the decisive context?

Contract framing

Integration discovery follows the operating record across every producer and consumer, asking which system owns an identifier, timestamp, state, confidence value, or approval. Valid transport is not enough when participants interpret the same field differently, so canonical semantics and change ownership are settled before adapters make those disagreements harder to see.

The same pass defines the transaction boundary. Identity delegation, validation, idempotency, ordering, retries, reconciliation, and dead-letter handling are designed around the consequence of an incomplete workflow. This turns failure behavior into part of the interface contract rather than an operational surprise left to unrelated support teams.

002Evidence-bounded work packages

Data, Platform & Systems Integration is delivered as inspectable engineering work. Each package states what enters the process, what leaves it, and what the evidence does not prove.

W01Assessment

Map systems of record, producers, consumers, owners, protocols, classifications, transaction boundaries, interface versions, and known failure history.

Inputs
Architecture diagrams, API and event schemas, data catalogues, identity model, network zones, sample payloads, logs, and change records.
Outputs
Integration inventory, authority map, data-flow model, trust boundaries, dependency graph, risk register, and prioritised interface backlog.
Boundary
The discovery represents the systems and evidence made available; undocumented shadow interfaces remain an explicit unknown until observed or supplied.
W02Engineering

Define canonical identifiers, schemas, event semantics, validation, lineage, ownership, versioning, and reconciliation around the required operating workflow.

Inputs
Representative records, source-of-truth decisions, business rules, quality constraints, event ordering needs, and retention requirements.
Outputs
Versioned contracts, validation rules, mapping specifications, lineage design, test fixtures, compatibility policy, and data-quality signals.
Boundary
Canonical contracts do not repair source-data quality by themselves; remediation ownership and acceptable-use decisions remain with the responsible data owners.
W03Engineering

Apply explicit identity, least privilege, resource policy, service authentication, secrets handling, network segmentation, and audit at every interface.

Inputs
Identity providers, service accounts, device identities, resource policies, classifications, secrets platform, and security architecture.
Outputs
Authentication and authorisation flows, policy decisions, credential lifecycle, service boundaries, negative tests, and access evidence.
Boundary
Alignment to Zero Trust principles is an architecture and engineering activity, not a declaration that the environment is certified or risk-free.
W04Prototype

Exercise the complete workflow under normal, delayed, duplicated, malformed, unauthorised, and unavailable conditions while preserving correlated evidence.

Inputs
Test environment, representative payloads, failure scenarios, performance budgets, security cases, trace identifiers, and acceptance criteria.
Outputs
Contract test suite, failure-injection results, trace map, dashboard specification, residual issues, cutover plan, and rollback evidence.
Boundary
Tests demonstrate behaviour for the agreed cases and environment; they do not guarantee every external dependency or future version.
003Reference architecture

This is a scoping architecture, not a claim that every product or environment uses the same stack. Interfaces and owners are confirmed against the actual deployment.

01

Layer 01

Establish source authority, ownership, identity, classification, freshness, and interface state for enterprise platforms, sensors, devices, and partner systems.

Typical elements

ERP, CRM, document repository, data platform, sensor gateway, mission system, identity provider, and vendor API.

02

Layer 02

Move validated records and events through versioned interfaces with explicit delivery, ordering, idempotency, lineage, and reconciliation rules.

Typical elements

API gateway, event bus, schema registry, stream processor, data product, dead-letter queue, and canonical identifier service.

03

Layer 03

Compose workflow state, model or agent calls, deterministic rules, resource policy, and human approvals without bypassing source-system controls.

Typical elements

Workflow engine, model gateway, policy decision point, tool adapter, approval service, and transaction coordinator.

04

Layer 04

Correlate source, transformation, policy, model, approval, write, release, error, and recovery evidence across service boundaries.

Typical elements

Distributed trace, audit event, data lineage, service-level signal, contract-test result, release manifest, and incident timeline.

Cutover journey

The architecture carries correlated identity from the authoritative source through transformation, policy, AI or workflow processing, human approval, and the destination write. Contract tests and failure injection then show whether delayed, duplicated, malformed, unauthorised, and unavailable conditions produce the declared response without losing decisive context.

Handover records interface owners, supported versions, observability signals, unresolved dependencies, cutover sequence, and rollback authority. A sampled outcome should be explainable across system boundaries by the receiving team, including which evidence came from a third party and which behavior remains outside the organisation's control.

004Operating profiles

These profiles show how the service changes by operating context. They are examples for scoping—not customer case studies or pre-approved outcomes.

U01

A programme must combine sensor observations, platform state, reference data, analytics, and operator approval across different timing and classification boundaries.

Primary user
Mission operator, systems engineer, data owner, security architect, and test lead.
Decision
Which observation is authoritative and fresh enough to support a recommendation, and which path applies when sources conflict or disappear?
Evidence
Timestamp and source identity, transformation lineage, model and policy versions, confidence state, operator action, and downstream disposition.

U02

Business units need governed access to sensitive data and AI services without creating duplicate pipelines or broad standing credentials.

Primary user
Data product owner, platform engineer, security team, risk owner, and application team.
Decision
Which reusable data and AI services can be exposed, under what policy, and how are access and derived outputs retained and reviewed?
Evidence
Data contract, policy decision, delegated identity, lineage, quality result, use-purpose record, and access audit.

U03

An agentic workflow needs controlled access to documents, tickets, customer records, messaging, and approval systems.

Primary user
Operations owner, application engineer, identity team, compliance reviewer, and service desk.
Decision
Which tool calls may be read-only, prepared, approval-gated, or prohibited, and how is a partial workflow recovered?
Evidence
Tool schema, permission decision, input and output validation, approval, idempotency key, write result, and correlated trace.
