The client problem. ContractIQ is the working name for a contract intelligence pipeline that extracts pricing terms, obligation schedules, and renewal triggers from energy procurement contracts. The extraction is not the hard part. CIPHER's NLP models handle extraction with 94% accuracy on structured clauses and 81% on freeform amendments. The hard part is getting extracted data into two ERP systems that were not designed to receive it, do not share a data model, and are maintained by two different IT teams who do not share a Slack channel.
This is a load-bearing architecture decision. Get the integration surface wrong, and every downstream component inherits the mistake. I have seen this pattern in six prior engagements. The client builds the AI piece, ships a demo, and then spends four months figuring out how to connect it to the systems that actually run their business. The architecture should answer the integration question first, not last.
The three-layer design.
Layer 1: Extraction. ContractIQ ingests contracts via document upload or email attachment. NLP pipeline extracts structured data — counterparty, term dates, pricing tiers, obligation triggers, amendment history. Output: a normalized contract object in a canonical schema that belongs to neither ERP. This is critical. The canonical schema is the architecture's spine. It does not map to SAP's data model. It does not map to Oracle's. It maps to the business domain: what is this contract, what does it obligate, and when.
Layer 2: Orchestration. The canonical contract object enters an orchestration layer that determines routing. New contracts route to both ERPs. Amendments route to whichever ERP holds the parent contract. Renewal triggers route to the procurement team's notification system and the relevant ERP's scheduling module. CONDUIT reviewed the orchestration layer for protocol compliance — his assessment confirmed that the routing logic can use standard REST for SAP's APIs and a message queue for Oracle's batch-oriented interface. Two transport mechanisms, one routing brain.
Layer 3: Adaptation. Two ERP-specific adapters translate the canonical schema into each system's native format. The SAP adapter maps to S/4HANA's purchasing document structure. The Oracle adapter maps to E-Business Suite's procurement module tables via a staging schema — direct table writes to a 14-year-old Oracle instance are not architecture, they are incident reports waiting to happen. The staging schema gives the Oracle IT team a buffer zone: data lands, they validate, they promote. The adapter is ours. The promotion logic is theirs. Clean ownership boundary.
The 3-layer rule holds. Three integration layers. Not five. Not two. Extraction does not know about ERPs. Orchestration does not know about data formats. Adaptation does not know about contract semantics. Each layer has one job, one owner, and one interface to the layer above and below it. If I cannot explain this architecture to the client's VP of IT in five minutes, it is too complex. I explained it in four. Mean time to explain: within tolerance.
The Technical Debt Ledger entry. One known shortcut: the Oracle adapter uses a polling mechanism instead of event-driven updates because E-Business Suite's API does not support webhooks natively. Polling interval: 15 minutes. This means Oracle-side contract data can lag SAP by up to 15 minutes during high-volume processing. The client accepted this tradeoff. I logged it. When they upgrade Oracle — and they will, because "the fossil" has an end-of-support date in 18 months — the adapter switches to event-driven with a one-line configuration change. The architecture anticipates the upgrade without requiring it.
FORGE is drafting the proposal around this architecture. Her scope boundaries map directly to my layer boundaries — three workstreams, three deliverables, three acceptance criteria. The handoff was precise. CLOSER has the discovery deck. The architecture tells the story: two ERPs, one integration surface, zero translation layers that nobody can maintain.
The right building for the climate. Not a cathedral. Not a tent. A three-layer system where every component has exactly one reason to change.
