The final record should let the buyer distinguish demonstrated behavior from proof scaffolding and commission production work without treating the estimate as assurance.
Package the demonstrated workflow
Include the approved workflow, architecture diagram, source and target interfaces, schema mappings, code revision, environment definition, fixture register, acceptance criteria, run evidence, failure evidence, and known-limits register. Mark proof-only elements such as hard-coded identifiers, sandbox credentials, simplified roles, manual setup, limited data volume, or recorded stubs. Identify reusable modules separately from scaffolding that should not enter production.
The OpenAPI description and generated clients can document HTTP operations, but the handoff also needs business mapping and target-state semantics. State which fields are copied, transformed, defaulted, rejected, or omitted, and which system owns each identifier. Preserve example requests and responses with secrets and unnecessary data removed. Link each acceptance result to the exact code and environment used for the run.
Demonstrate reset and fallback
Run the reset from a completed proof and verify both systems return to the defined starting state. Then demonstrate the agreed fallback for one unavailable dependency or rejected operation. The fallback may queue a record, create a review item, use a recorded stub, or stop with a traceable error. It should not silently claim success or perform an unapproved external action.
Record who can operate reset and fallback, the permissions required, the expected artifacts, and the observed duration. A proof fallback is evidence for one scenario, not a resilience, disaster-recovery, or uptime assurance. Production design may require queues, replay controls, rate limiting, monitoring, support ownership, data recovery, and provider agreements that are deliberately absent from the evaluation environment.
Estimate production work from named assumptions
Break the estimate into production identity, connectivity, workflow implementation, data mapping, observability, testing, deployment, documentation, support handoff, and buyer-managed review. State assumed systems, roles, volumes, environments, regions, criteria, and dependencies. Give a range and list decisions that could change it. Keep security, privacy, compliance, procurement, and platform licensing work outside the estimate unless separately scoped by qualified owners.
Reality Contact, LLC prepares this handoff through Integration Proof Record for the buyer's prospect review. The buyer and prospect decide whether the proof meets the agreed evaluation criteria and whether to commission production implementation. The estimate is a bounded planning artifact based on current proof facts. It is not a fixed production quote, architecture approval, security or compliance assurance, or promise of implementation or business outcomes.
Where the service stops
Reality Contact, LLC builds a one-workflow evaluation artifact but does not certify security, privacy, compliance, reliability, scalability, production readiness, procurement fit, or business outcomes; approve enterprise architecture; operate production; or represent the prospect's acceptance decision. The buyer and prospect approve the workflow, claims, sanitized data, constraints, target-system actions, and acceptance criteria; control credentials and access; attend the evidence review; and decide whether to commission a separately scoped production implementation. The service is software implementation and document preparation for one evaluation workflow, and it does not replace security, privacy, compliance, architecture, procurement, reliability, or production review. The buyer and prospect approve the workflow, data, claims, access, and acceptance criteria and retain every production, procurement, architecture, and commissioning decision.
