Document processing pipeline architecture
Files land in storage, an agent extracts structured fields, a person approves anything low-confidence, and the result is written to the database.
Every resource, and what it costs.
Projections from August 2026 list prices for always-on resources. Connect an account and these become the figures your provider actually bills.
| Node | Type | What it is | Projected |
|---|---|---|---|
| Upload bucket | Storage | 100 GB standard | $3.00/mo |
| Extraction queue | Messaging | 5M requests | $2.00/mo |
| Records database | Database | db.t4g.large · single-AZ · 100 GB | $105/mo |
| Processed archive | Storage | 1 TB deep archive | from $4.00/mo |
| New object | Trigger | S3 event notification | — |
| Extract fields | Agent step | Structured extraction against a schema | billed per token |
| Resolve mismatches | Agent step | Only when confidence is low | billed per token |
| Approval gate | Guardrail | Low-confidence extractions need review | enforced at runtime |
| erp_write | Tool | Writes the record to the ERP | — |
| Budget cap | Guardrail | Halts runs over $250/mo | enforced at runtime |
| ArcFoundry runtime | Runtime | — | — |
Agent steps are priced from provider-reported token usage once the agent runs, not estimated. Guardrails cost nothing and are the reason a runaway agent cannot. One row shows from because those services bill by usage, so the total is a scenario at the stated volumes, not a quote.

Support agent on live systems
A support agent that reads the orders database and writes back through an approval gate. Agent steps and the systems they touch on one graph.
Agent with enforced write control
The pattern for letting an agent touch production: every write passes an approval gate, every action lands in a hash-chained evidence log.
Retrieval service (RAG)
An answer endpoint over your own documents: vector store, retrieval step, generation step, cached responses.
